Description

[Detailed description of the invention] "Field of industrial application" This invention relates to a pin jack used in combination with a pin plug.

``Prior Art'' A pin jack has contacts housed within a cylindrical body made of insulating material, and a metal cover is attached to the outside of the body. Conventional metal covers have a cylindrical structure that covers the entire circumference of the body. As a result, material costs were high, plating costs were high, and the molds were also expensive because they were made by squeezing.

"Means for Solving the Problem" According to this invention, a shallow recess is formed in the circumferential surface of a cylindrical body made of an insulating material, and an arc-shaped metal cover is fitted into the shallow recess. Further, grooves extending along the axial direction are formed on both sides of the shallow recess, and both side edges of the cover are bent and inserted into these grooves. Furthermore, the collar formed on the body and the cut-and-raised piece formed on the cover are engaged to prevent the cover from coming off.

"Embodiment" FIGS. 1 and 2 show an embodiment of this invention. A cylindrical body 11 made of an insulating material is integrally formed with a collar 12 at its rear end, and a shallow recess 13 is formed in a part of the circumferential surface of the body 11. An arcuate hole 14 is formed in the collar 12 in communication with the rear end of the shallow recess 13.

A metal arc-shaped cover 15 is fitted into a shallow recess 13 of the body 11. As shown in FIG. 3, axial grooves 16 are formed on both sides of the shallow recess 13, and both side edges 17 of the cover 15 are bent and inserted into these grooves 16. In other words, cover 15
from the rear side of the body 11 to the front edge 1
7 is inserted into the groove 16 and fitted into the shallow recess 13 through the arcuate hole 14. In this case, the edge of the edge 17 may be in contact with the bottom of the groove 16, and the inner circumferential surface of the cover 15 may not be in contact with the bottom of the shallow recess 13 to form a gap 18, as shown in FIG. preferable. The circumferential length of the cover 15 is the body 11
It is recommended that the angle be approximately 120° with respect to the axis of the A terminal 19 is integrally formed at the rear end of the cover 15. A cut-and-raised piece 21 is cut and raised on the cover 15,
When the cover 15 is inserted into the shallow recess 13, the cut and raised piece 21 engages with the collar 12 to prevent the cover 15 from coming off. A circumferential rib 22 protrudes from the cover 15.

As shown in FIG. 2, for example, a hawk-shaped contact 23 is inserted and held in the body 11 along the axial direction. A terminal 24 is integrally formed with the contact 23.

As shown in FIG. 4, the cover 15 may be inserted into the shallow recess 13 of the body 11 from the front. Further, the terminals 19 and 24 may extend parallel to the axis instead of extending in a direction perpendicular to the axis.

``Effect of the invention'' As mentioned above, in this invention, Cover 1
5 covers not the entire circumferential surface of the body 11 but a part of the circumferential surface, so the material cost of the cover 15 is cheaper than before, the plating cost is also cheaper, and the cover is not made by squeezing. It can be easily made using a press mold.

Both side edges 17 of the cover 15 are bent inward,
The both side edges 17 are fitted into the grooves 16 of the body 11, and the cover 15 is effectively attached to the body 11.

There is a gap of 1 on the circumferential surface of the body 11 and the cover 15.
8, when inserting and removing the plug, cover 15
elasticity is obtained. The cut and raised pieces 21 of the cover 15 can stop the cover 15 from moving backward or forward. When the rib 22 is provided, it is possible to provide stability in contact with the plug.

If the cover 15 is further extended over 120°, the fifth
As shown in the figure, the cover 15 can be in contact with the cover 25 of the plug at two or more points, as shown in FIG. 6, with respect to the plug.
