`
`
`
`[Scope of Claims]
`[Claim 1] In the context of a coaxial plug wherein a ring shaped
`connecting part fitted to the head part of a coaxial plug nut is
`rotatably connected to a connecting groove provided in the outer
`periphery of the distal end portion of a coaxial plug sleeve, and a
`coaxial connector is attached by means of a threaded groove formed
`on the inside of the aforementioned nut, a coaxial plug for
`electronic equipment characterized by being equipped with a
`connecting protrusion provided along the inner peripheral surface of
`the connecting portion of the aforementioned nut, which makes
`sliding contact with the peripheral surface of the connecting groove
`that is formed in the aforementioned sleeve, an extension portion
`that is formed by the extension of the attachment port of the coaxial
`connector, a groove that is provided on the inside of this extension
`portion, a contact spring that is provided inside this groove and
`presses against the aforementioned coaxial connector, and a
`retaining ring fitted to the aforementioned sleeve that fixes the
`position of the coaxial cable.
`[Detailed Description of the Invention]
`[0001]
`[Technical Field of the Invention] The present invention relates to a
`coaxial plug for electronic equipment that minimizes ingress noise
`when the connector is connected to, for instance, a CATV device.
`[0002]
`[Prior Art] Previously, for instance in the context of a CATV system,
`etc, the coaxial plug that is attached to the coaxial connector of an
`electronic device has been constituted as shown in Figure 3. Figure
`3 is a drawing that shows a partial cutaway of an existing coaxial
`plug 1. The aforementioned coaxial plug 1 comprises coaxial plug
`nut 2, coaxial plug sleeve 3 and retaining ring 4. The
`aforementioned coaxial plug nut 2 has formed on its inside a
`threaded groove 5 that screws together with a coaxial connector, and
`is open at its head part, and the peripheral edge of this opening is
`formed in a ring shape to serve as a connecting part 6 to sleeve 3.
`Meanwhile, coaxial plug sleeve 3 protrudes at the end portion of the
`side which connects to coaxial plug nut 2 to form connecting groove
`7, and the ring shaped connecting part 6 of the aforementioned
`coaxial plug nut 2 is positioned from the outside of this connecting
`groove 7 to connect it with coaxial plug nut 2. In this case, the ring
`shaped connecting part 6 of coaxial plug nut 2 is provided slidably
`within the connecting groove 7 of coaxial plug sleeve 3. That is to
`say, coaxial plug nut 2 is connected rotatably with respect to coaxial
`plug sleeve 3.
`[0003] And, coaxial cable 11 is attached to the aforementioned
`coaxial plug 1. This coaxial cable 11 comprises skin 12, outer
`conductor (braided wire) 13, insulator 14 and central conductor 15.
`[0004] In the case that coaxial cable 11 is connected to the
`aforementioned coaxial plug 1, the distal end of coaxial plug sleeve
`3 is inserted between outer conductor 13 and insulator 14 of coaxial
`cable 11, and is fixed by crimping from the outside of skin 12 with
`retaining ring 4. In this manner, a ground connection is made with
`outer conductor 13 of coaxial cable 11.
`[0005] To connect the coaxial plug 1 constituted as above to the
`coaxial connector of a device, the threaded part of the coaxial
`connector is inserted into the threaded groove 5 of coaxial plug nut
`2, and coaxial plug nut 2 is rotated to affix the two together. At this
`time, the central conductor 15 of the coaxial cable 11 electrically
`connected by pressing it against the center contact of the coaxial
`connector.
`[0006] [Problems to be Solved by the Invention] When the above
`existing coaxial plug 1 is attached to the coaxial connector of an
`electronic device, while rotating coaxial plug nut 2 to fasten the
`
`JP2000-40564A
`
`threaded part of the coaxial connector, the contact between the
`external shells which are the grounding parts is not made reliably,
`and is in an extremely unstable state. That is to say, under the above
`existing coaxial plug 1, when tightening has not been completed
`during connection with a coaxial connector, the contacts between
`coaxial plug nut 2 and coaxial plug sleeve 3, and between coaxial
`plug nut 2 and the coaxial connector are not made reliably. When
`the aforementioned coaxial plug 1 is attached to the coaxial
`connector of an electronic device, in particular the coaxial
`connector of an electronic device in the context of a CATV system,
`the problem exists that if contact between the outer shells which are
`the grounding parts is in a state which is not sufficient, the
`connector will be in an open condition, resulting in the influx of
`external noise becoming extremely high, and causing interference in
`the form of ingress noise to the CATV system.
`[0007] The present invention has been made in order to resolve the
`above problem, and aims to provide a coaxial plug for electronic
`equipment that allows reliable contact between the outer shells that
`are the grounding parts even while being attached to a coaxial
`connector, reliably preventing contamination with ingress noise.
`[0008] [Means of Resolving the Problems] In the context of a
`coaxial plug wherein a ring shaped connecting part fitted to the head
`part of a coaxial plug nut is rotatably connected to a connecting
`groove provided in the outer periphery of the distal end portion of a
`coaxial plug sleeve, and a coaxial connector is attached by means of
`a threaded groove formed on the inside of the aforementioned nut,
`the present invention is characterized by being equipped with a
`connecting protrusion provided along the inner peripheral surface of
`the connecting portion of the aforementioned nut, which makes
`sliding contact with the peripheral surface of the connecting groove
`that is formed in the aforementioned sleeve, an extension portion
`that is formed by the extension of the attachment port of the coaxial
`connector, a groove that is provided on the inside of this extension
`portion, a contact spring that is provided inside this groove and
`presses against the aforementioned coaxial connector, and a
`retaining ring fitted to the aforementioned sleeve that fixes the
`position of the coaxial cable.
`Invention] Hereinafter, one
`the
`[0009]
`[Embodiments of
`embodiment of the present invention is explained with reference to
`the drawings.
`[0010] Figure 1 is a partial cross sectional view that shows the
`construction of the coaxial plug for electronic equipment of one
`embodiment of the present invention, while Figure 2 is a partial
`cross sectional view that shows the state of the coaxial plug of the
`said embodiment in the state of being connected to a coaxial
`connector.
`[0011] Coaxial plug 1 comprises coaxial plug nut 2, coaxial plug
`sleeve 3 and retaining ring 4. The aforementioned coaxial plug nut 2
`has formed on its inside a threaded groove 5 that screws together
`with a coaxial connector, and is open at its head part, and the
`peripheral edge of this opening is formed in a ring shape to serve as
`a connecting part 6 to sleeve 3. This ring shaped connecting part 6 is
`further provided with a connecting protrusion 8 along its inner
`peripheral surface. In addition, the aforementioned coaxial plug nut
`2 is formed by extension of the attachment side of the coaxial
`connector, and groove 9 is formed along the inside peripheral
`surface of this extended part 2a, and contact spring 10 is provided
`inside this groove 9. This contact spring 10 protrudes slightly from
`the inner peripheral surface of the aforementioned extended part 2a,
`such that upon attachment with a coaxial connector, it abuts with the
`said coaxial connector.
`
`

`
`
`
`[0012] Meanwhile, coaxial plug sleeve 3 protrudes at the end
`portion of the side which connects to coaxial plug nut 2 to form
`connecting groove 7, and the ring shaped connecting part 6 of the
`aforementioned coaxial plug nut 2 is positioned from the outside of
`this connecting groove 7 to rotatably connect it with coaxial plug
`nut 2. In this case, each dimension of the connecting protrusion 8
`provided to ring shaped connecting part 6 is set such that it makes
`sliding contact with the peripheral surface of the connecting groove
`7 of coaxial plug sleeve 3, in order that coaxial plug nut 2 and
`coaxial plug sleeve 3 are continuously electrically connected.
`Moreover, in the case that the aforementioned coaxial plug sleeve 3
`is connected to coaxial plug nut 2, the outer diameter of the end
`portion on the side that connects with coaxial plug nut 2 of coaxial
`plug sleeve 3 is formed to match the diameter of ring shaped
`connecting protrusion 8 of coaxial plug nut 2, such that after the
`distal end portion thereof is inserted into ring shaped connecting
`protrusion 8, a tapered fixture is pressed into and expands in this
`inserted end portion from the front end opening of coaxial plug nut
`2 in order to connect it to coaxial plug nut 2.
`[0013] And, coaxial cable 11 is attached to the aforementioned
`coaxial plug 1. This coaxial cable 11 comprises skin 12, outer
`conductor (braided wire) 13, insulator 14 and central conductor 15.
`[0014] In the case that coaxial cable 11 is connected to the
`aforementioned coaxial plug 1, the distal end of coaxial plug sleeve
`3 is inserted between outer conductor 13 and insulator 14 of coaxial
`cable 11, and is fixed by crimping from the outside of skin 12 with
`retaining ring 4. In this manner, a ground connection is made with
`outer conductor 13 of coaxial cable 11. In addition, although central
`conductor 15 of coaxial cable 11 is inserted within coaxial plug 1,
`the position of its tip is set to be sited slightly inwards from contact
`spring 10.
`[0015] And, as shown in Figure 2, the aforementioned coaxial plug
`1 is attached to coaxial connector 21. This coaxial connector 21 has
`a threaded part 23 that screws together with the threaded groove 5
`of the aforementioned coaxial plug nut 2 on the outside of shell 22.
`Furthermore, the central section of the aforementioned shell 22 is
`provided with a female center contact 24 that makes contact with
`the central conductor 15 of coaxial cable 11.
`[0016] In the case that the coaxial plug 1 constituted as above is
`attached to the coaxial connector 21 of an electronic device, when
`extended part 2a of coaxial plug nut 2 is inserted into coaxial
`connector 21, firstly, contact spring 10 presses against threaded part
`23 of coaxial connector 21, and coaxial plug nut 2 and coaxial
`connector 21 are electrically connected. In addition, coaxial plug
`nut 2 and coaxial plug sleeve 3 are electrically connected by the
`connecting protrusion 8 provided to the ring shaped connecting part
`6 of coaxial plug nut 2. Accordingly, when coaxial plug 1 is
`connected to coaxial connector 21, the outer shells that are the
`grounding parts maintain a reliably connected state.
`
`
`
`(3)
`
`JP2000-40564A
`
`[0017] In the above state, coaxial connector 21 is further inserted
`into coaxial plug nut 2, and threaded part 23 of coaxial connector 21
`is brought into contact with threaded groove 5 while coaxial plug
`nut 2 is rotated, in order to fix the two together by fastening. At this
`time, the central conductor 15 of the coaxial cable 11 electrically
`connected by pressing it against the female center contact 24 of the
`coaxial connector. In addition, even in the state wherein the
`aforementioned coaxial plug nut 2 is being rotated to fasten it to
`coaxial connector 21, the external shells are maintained in a state of
`reliable contact by means of the connecting protrusion 8 and contact
`spring 10 provided to the aforementioned ring shaped connecting
`part 6. Consequently, even when coaxial plug 1 and coaxial
`connector 21 are connected, the influx of external noise from
`between coaxial plug nut 2 and shell 22 of coaxial connector 21,
`and between coaxial plug nut 2 and coaxial plug sleeve 3 is able to
`be prevented, and even when used in, for instance, a CATV system,
`interference caused by ingress noise is able to be reliably prevented.
`[0018] [Effects of the Invention] Under the present invention as
`explained in detail above, in the context of a coaxial plug in which a
`coaxial plug nut is combined with a coaxial plug sleeve, a
`connecting protrusion is provided to the connecting part of the nut
`combined with the aforementioned sleeve to make it constantly
`contact the aforementioned sleeve, and, the aforementioned nut
`extends from the attachment port of the coaxial connector, and a
`contact spring is provided to this attachment port such that it abuts
`the outer peripheral surface of a coaxial connector, and thereby,
`when connecting the coaxial plug to a coaxial connector, reliable
`contact is able to be made between the external shells which are the
`grounding parts, and contamination with ingress noise is able to be
`reliably prevented.
