Description

[Detailed description of the invention] [Summary] In a connector equipped with a metal case to prevent static electricity and radio waves, the nut used to attach to the device using a machine screw is inserted into a recess in the molded body and used for shielding. The nut can be easily assembled by being covered with a portion of the metal case.

[Industrial application field]

The present invention relates to improvements in connectors, particularly connectors equipped with a metal case to prevent static electricity and radio waves.

[Conventional technology]

FIG. 3 is a perspective view showing an example of the configuration of a conventional connector (plug). A plug 1 configured for static electricity and radio wave countermeasures consists of a molded body 2 made of plastic and having a plurality of contacts 4 implanted therein. and a metal case 3 that covers the part exposed from the device when the molded body 2 is attached to the device,
A contact embedded in a molded body of a jack (not shown) is connected to the contact 4.

Near both longitudinal ends of the molded body 2 are a nut 5 for fixing the jack, a through hole 6 into which a machine screw (not shown) for attaching the molded body 2 to the device is inserted, and a metal case. It has a notch (not shown) for attaching the 3.

The metal case 3, which exposes the jack contacting surface of the molded body 2, has a through hole 8 facing the screw hole of the nut 5, and a tongue piece 9 facing the notch of the molded body 2. The tongue piece 9 is bent along the notch so as to hold the mold body 2.

FIG. 4 is a side view showing another example of the configuration of a conventional connector (plug).

In FIG. 4, which uses the same reference numerals for parts common to those in FIG. 3 and is partially cut away, a plug 11 configured for static electricity and radio wave countermeasures is made of plastic molded and has a plurality of contacts 4 implanted therein. It consists of a molded body 12 and a metal case 3 that covers the portion exposed from the device when the molded body 12 is attached to the device.

Near both ends of the mold body 12 in the length direction,
A through hole 13 through which a machine screw (not shown) for attaching the mold body 12 to the device is inserted, a through hole 14 through which a machine screw (not shown) for fixing the jack to the mold body 12 is inserted, and a metal It has a notch 15 for attaching the case 3.

The through hole 7 of the metal case 3 exposing the jack contact surface of the molded body 12 faces the through hole 14, and the tongue piece 8 is bent into a notch 15.

In order to fix a jack (not shown) to such a plug 11, a machine screw is fitted through the through holes 7 and 14, and a nut is screwed into the machine screw.

[Problem that the invention attempts to solve]

In conventional connectors, the nut is inserted into the molded body as shown in Figure 3.
Since nuts must be placed in the mold prior to mold formation, there is a problem in that the efficiency of the molding operation is low, and as shown in Figure 4, the mold body without nuts requires no work to fix the jack. The problem was that it was inefficient.

[Means for solving problems]

The connector of the present invention, which aims to eliminate the above-mentioned problems, has a molded body 22 in which a plurality of contacts 4 are implanted, and a recess 23 in which the inserted nut 5 is accommodated without rotating. A first through hole 24 through which a screw can be inserted to be inserted into the screw hole of the nut 5 inserted into the mold body 22 is provided. A second through hole 8 is provided in a portion covering the recess 23, into which a screw can be inserted to be screwed into the screw hole of the nut 5 inserted into the recess 23.

[Effect]

According to the above means, by attaching the metal case to the mold body, the nut inserted into the recess of the mold body is supported, so the nut can be inserted to form the mold body, and the through hole of the mold body can be formed by inserting the nut. This eliminates the conventional problem of manually threading a nut onto a machine screw inserted into the machine.

〔Example〕

EMBODIMENT OF THE INVENTION Below, the connector which becomes the Example of this invention is demonstrated using drawing.

FIG. 1 is an exploded perspective view of a connector (plug) according to an embodiment of the present invention, and FIG. 2 is a partially cutaway side view of the connector.

In FIGS. 1 and 2, in which the same reference numerals are used for common parts in FIG. 22, a metal case 3 that covers the part exposed from the device when the molded body 12 is attached to the device, and a pair of nuts 5 that are inserted into the molded body 22 and covered by the metal case 3, and are connected to the contacts 4. The contacts embedded in the molded body of the jack (not shown) are connected.

Near both ends of the mold body 22 in the length direction,
A recess 23 into which the nut 5 for fixing the jack is inserted, a through hole 24 opening in the center of the recess 23, and a machine screw (not shown) for attaching the mold body 22 to the device inserted therethrough. It has a through hole 25 and a notch 26 for mounting the metal case 3. The recess 23 has the same hexagonal shape as the nut 5 as shown in the figure so that the inserted nut 5 can fit therein without rotating.

A through hole 24 faces the through hole 8 of the metal case 3 that exposes the jack contact surface of the molded body 22, and the nut 5 is inserted into the pair of recesses 23 and fitted to the front surface of the molded body 22. The plug 21 is completed by bending the tongue piece 9 of the metal case 3 along the notch 25.

The plug 21, which is constructed in this way and corresponds to the conventional plugs 1 and 11, is fitted with the same jack as the one that is fitted into the plugs 1 and 11, and then the tip of a small screw inserted through the through hole of the jack is inserted. The part comes to be screwed together with the nut 5. As a result, the jack is fixed to the plug 21.

[Effect of idea]

As explained above, according to the present invention, in a connector with a metal case, the conventional problem that the productivity of the molded body cannot be improved by embedding the nut in the molded body with an insert, or that the nut is not supported by the molded body can be solved. The use of nuts has the effect of eliminating the conventional problems that hindered the workability of screwing.
