Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a connector housing, and more particularly, to a connector housing that accommodates contacts as coupling members used to connect electronic circuits between devices.

[Prior Art] There have been many proposals and many technologies have been disclosed for a device that inserts a contact to which a conductor is connected to a connector housing and locks the contact so as not to be separated.

Now, raising the main ones of the prior art, the actual development 55-
9228, JP-A-58-212082, JP-A-59-117079 and JP-A-59-117080. However, the means for loading and locking the contact terminals in the connector housings described in these publications have some disadvantages.

As a solution to these problems of the prior art,
There are the techniques described in 61-168575 and 62-99177.

When examining the technical contents disclosed in both of these publications,
Together, they eliminate the drawbacks of the earlier prior art. However, in both cases, a member for locking the terminal accommodated in the housing is formed outside the connector housing, and the extremely important engaging portion is exposed to the outside of the connector housing.

Therefore, if some external force is applied to the connector housing, there is a risk of damaging the important locking member and engaging portion.

Further, since the locking member is projected to the outside of the connector housing, there is a problem that the outer dimensions of the connector body are increased.

[Object of the Invention] In view of the above-mentioned problems of the prior art, the main object of the present invention is to properly lock the contacts in the connector housing without exposing the locking portions to the outside. An object of the present invention is to provide a connector housing in which the stop member is not damaged by an external force.

[Structure of Device] The preferred embodiment of the device will be described. As shown in FIG. 1, the connector housing 10 of the present invention is a rectangular block made of an insulator. This housing 10 is a third
As shown in the figure, a plurality of socket contacts 12 each having a conventionally used conductor M attached to a holding portion H and a tip portion configured as a connection portion C for receiving a pin contact (not shown in the drawing) One is inserted by inserting it from one end of the housing 10, and the other is connected by inserting a pin contact from the other end.

To accommodate each socket contact 12 in the housing 10, the housing 10 is separated by a side wall 14, a top wall 16 and a bottom wall 18.
A contact accommodating chamber 20 partitioned by and is formed extending in the longitudinal direction of the housing 10.

The accommodation chamber 20 is formed with an inward projection 21 for supporting the holding portion H of the inserted contact 12 in cooperation therewith.

On the other hand, the top wall 16 is slightly higher than the remaining portion from the end on the side where the contact 12 is inserted to a predetermined distance, and the top wall 16 on the high side and the top wall 17 on the low side with a slight step. It is said that.

From this part of the top wall 16 on the high side to the part of the top wall 17 on the lower side, an opening 2 having a width slightly narrower than the space between the side walls 14, 14.
2 is formed.

A strip member 24, which is slightly narrower than the opening 22, extends from the end of the opening 22 of the top wall 16 on the higher side along the opening 22. The strip-shaped member 24 is integral with the top wall 16 and is slightly longer than the length of the opening 22 of the top wall on the higher side, and has a desired flexibility due to its material. The other end of each belt-shaped member 24 ends in an independent locking member 26 and cantilevers it.

The end of the locking member 26 on the side of the belt-shaped member 24 has the top wall on the higher side.
The step between 16 and the lower top wall 17 forms a slight rear protrusion 28 that allows it to mate with the backside of the higher top wall 16.

The locking member 26 is provided with an operating ridge 30 for operating the contact 12 after inserting the contact 12 into the accommodation chamber 20, and the front protrusion 32 is provided at the front end thereof so as to come into contact with the back surface of the lower top wall 17 and has a comb tooth. It is formed into a shape.

A portion between the roots of the rear protrusion 28 and the front protrusion 32 of the locking member 26, that is, the base of the raised portion 30 is sized so as to close the opening 22 in the portion of the lower top wall 17.

FIG. 5 shows an embodiment of the connector housing of the present invention which is applied to a form in which the contact accommodating chambers 20 are arranged in two rows in the vertical direction. The structure is substantially the same as that described with reference to FIGS. 1 to 3.

[Operation and Effect of the Invention] Since the connector housing 10 of the present invention is constructed as described above, first, the contact 12 in which the conductor M is connected is inserted into the contact accommodating chamber 20 of the housing 10. Then, the projecting end of the conductor holding portion H of the contact 12 passes through the inward projecting portion 21 of the accommodation chamber 20, and the contact 12 is accommodated
Can be installed within 20.

Therefore, as shown in FIG. 4, the locking member 26 that has been lifted up to that time is operated so that the forward protrusion 32 at the tip of the operation protrusion 30 is moved to the opening 22 of the top wall 17 on the lower side. Through protrusion 32
Under the top wall 17 on the lower side. Next, when the finger-hanging ridge 30 is pushed further forward and the ridge 30 is pushed toward the top wall 16, the rear protrusion 28 of the locking member 26 passes through the opening 22 and reaches the lower surface of the top wall 16 on the higher side. Engage and lock (Fig. 4).

As will be apparent from the above description, after inserting the socket contact 12 into the accommodation chamber 20 of the housing 10, the protrusions 28 and 32 at both ends of the operating ridge 30 of the locking member 26 are provided on the upper side of the upper wall. The locking member 26 closes the opening 22 and is securely fixed at that position by locking the back surface of each of the lower wall 16 and the top wall 17 on the lower side, so that the locking member 26 does not come off even if external force is applied later. .

Further, the front protruding portion 32 of the locking member 26 is a connector housing 10
The socket contact (12) positioned behind the inward protruding portion (21) of the housing chamber (20) and inserted into the housing chamber (20) is properly prevented.

Further, the strip-shaped member 24 connecting the locking member 24 to the upper side top wall 16 of the housing 10 is housed in the corresponding portion of the opening 22 at the closed position of the locking member 26 and is not exposed to the outside. .
