Description

[Detailed description of the invention] [Industrial field of application] The present invention is a connector for electrically connecting and separating devices, and in particular protects the lead-out portion of a cable connected to the contact of the connector. Regarding the structure of the connector cover.

[Conventional technology]

Connectors that facilitate electrical connection and separation between devices and between devices and units/components are composed of electrically conductive contacts and insulators that protect them. Some of these devices are equipped with a cover to protect the lead-out portion of the cable connected to the contact.

FIG. 6 is a perspective view showing a conventional connector with a cover, particularly the relationship between the insulator housing the contacts and the cover.

In FIG. 6, 1 is an insulator (connector body) containing a plurality of contacts, 2 is a flat cable in which the tip of each core wire 3 is connected to each of the contacts, and 4 is the connection of the flat cable 2. A pair of covers 4
is inserted so as to surround the upper part of the insulator 1 by suitable locking means or screwing means.

That is, the width dimension W _-1 of the pair of inserted covers 4
and depth dimension B _-1 are both width dimension W _-2 of insulator 1
and the depth dimension B _-2 , and the space for mounting the insulator 1 or the mating connector to which the insulator 1 is inserted on a printed wiring board, etc. is determined by the dimensions required for the pair of covers 4. Ru.

[Problem that the invention attempts to solve]

Therefore, in conventional covered connectors, the cover, which does not have the essential function of electrically connecting and separating devices, determines the connector installation space, especially when multiple connectors are installed in parallel. When doing so, there was a problem in that the efficiency of the mounting space was significantly impaired.

[Means for solving problems]

The above problem is solved by having a molded body made of insulating resin in which a plurality of contacts are housed, and a pair of covers supporting the lead-out portions of a plurality of covered wires, one end of which is connected to each of the contacts. The molded body has one opposing side surface.
The cover has a pair of semicircular protrusions on the lower side and a square protrusion in the middle, and the cover is supported by sandwiching opposite sides of the molded body with the pair of U-shaped abutments. The cover has a protrusion on one side and a recess on the other side to be mutually locked, and each of the covers has a recess that fits into a semicircular protrusion on the opposite side. and a recess that fits into a rectangular protrusion, and the cover is provided with a connector configured such that each of the pair of recesses is rotatably supported on the protrusion. It will be resolved.

[Effect]

According to the above means, it is possible to form one side surface of the cover in alignment with the side surface of the insulating molded body that is not provided with a protrusion for fitting and supporting the cover, so that the cover does not protrude in the direction of the side surface. As a result, the mounting space for the connector can be made smaller than before.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1 is a perspective view showing the appearance of a connector according to an embodiment of the present invention, Fig. 2 is a side view with the cover of the connector opened, and Fig. 3 is a perspective view showing the appearance of the molded insulator of the connector. , FIG. 4 is a perspective view showing the appearance of the cover of the connector.

In FIGS. 1 and 2, 11 is a molded body (insulator) of insulating resin containing a plurality of contacts, 12 is a cover formed by molding insulating resin, and 13 is a plurality of covered wires arranged in parallel. The integrated flat cable 14 is a core wire of the coated wire, and the tip of each core wire 14 is connected to the opposing contact.

In addition, W _-3 is the width dimension of the main body part of the insulating molded body 11, B _-3 is the depth dimension of the insulating molded body 11, W _-4 is the width dimension of the cover 12, and B _-4 is the sum of the pair of covers 12. The depth dimension is B _-3 =B _-4 because the pair of covers 12 are configured to meet on opposite sides and on the upper part of the mold body 11.

In FIG. 3, a molded body 11 having a through hole 11e into which a plurality of contacts are inserted has a pair of semicircular cross sections in the middle part on one opposing side, that is, on each opposing side surface 11a in the width W _-3 direction. The opposing protrusions 11b and 11c are integrally formed with a protrusion 11d having a rectangular cross section on the upper part.

In FIG. 4, the cover 12, which is substantially U-shaped when viewed from the front, has a recess 12a that fits into the semicircular projection 11b, and a square projection 1 on each of the opposing U-shaped pieces.
A recess 12b that fits into the mold body 1d is formed, and a tongue-like piece 12c that projects in the depth B _-3 direction of the mold body 11 projects from one side, and a recess 12d is formed at the other side.

Note that FIG. 5A is a cross-sectional view showing the shape of the tongue 12c, and FIG. 5B is a cross-sectional view showing the shape of the recess 12d. Although the projection 12e protrudes, a recess 12f having substantially the same shape as the protrusion 12e is formed in the recess 12d.

Therefore, when a pair of covers 12 are inserted facing each other as shown in FIG. 1, so that each recess 12a is fitted with a semicircular projection 11b, each cover 12 is inserted into an appropriate position with the projection 11b as an axis. It can be rotated by an angle. Therefore, a pair of covers 12 are fitted and inserted.
When both of them are rotated in opposite directions, one of the tongues 12c is inserted into the other recess 12d, and the opposing protrusion 12e and recess 12f are engaged.
A flat cable 13 is clamped.

When _the connector configured in this way _is applied to the conventional connector described using FIG. W _-2 ,
Although it is formed in the same manner as B _-2 , the overall width of the molded body 11 is the same as the width W _-4 of the cover 12, which is twice as large as the length of the semicircular projection 11b.

The width dimension W _-4 of the cover 12 is almost the same as the width dimension W _-1 of the conventional cover 2, and
Depth dimension B _-4 of 2 is the depth dimension of mold body 1
Since they are formed to have the same dimensions as B _-1 , when comparing the pair of covers 12 and the pair of covers 2, W _-4 =
W _-1 , B _-4 < B _-1 .

In the above embodiment, the cover 1 is rotatably supported on the semicircular projections 11b and 11c.
2, when the cover 12 is closed, the recess 12b holds the corner protrusion 11d from both sides. Therefore,
When the pair of covers 12 are engaged, the center of the dimension in the depth direction coincides with the center of the molded body 11.

Further, in the above embodiment, the pair of covers 12 are engaged with each other by the protrusion 12e and the recess 12f, but the present invention is not limited to such engagement means; for example, a hemispherical boss and a hemispherical concave It should be noted that this can be implemented by other means such as fitting with a place.

[Effect of idea]

As explained above, the present invention has a remarkable practical effect in that the mounting space for the covered connector can be narrowed and the mounting efficiency can be increased compared to the conventional method.
