Description

Description: TECHNICAL FIELD This invention relates to electrical connectors, and more particularly to an improvement in an electrical connector having an actuator member as one of the means for engaging male and female housings.

BACKGROUND OF THE INVENTION Electrical connectors having male and female housings and an actuator as one of the means for engaging the housings are known, for example, from US Pat. No. 4,512,621.

However, in this connector, the actuator portion is provided in contact with the arrangement direction (longitudinal direction) of the contacts (contacts) #, so the width of the housing (female type) increases accordingly, and the mounting area when attached to a printed circuit board etc. increases. Therefore, it is unsuitable for applications where it is required to mount many parts in as small an area as possible.

OBJECTS OF THE INVENTION An object of the present invention is to eliminate these conventional problems.

A further object of the present invention is to provide a level difference in the arrangement of contacts provided in the housing to disable connection with a plurality of cables, thereby further improving the degree of integration.

SUMMARY OF THE INVENTION The gist of this jaw development is as follows: a male housing, a female housing provided with a storage cavity for accommodating the 73 type housing, and a female housing provided on the male and female housings for engaging the male and female housings. A uC electrical connector comprising an engaging means and a connecting means provided on the male and female housings for four-way connecting the male and female housings, the connecting means provided on the male housing having one end a first contact having a connecting end for connecting at least one cable; and a plurality of first contacts having connecting ends for connecting with a connecting means provided on the female housing; , the first contacts/'i are provided in the male housing at regular intervals, the other end of the first contacts are exposed to the outside at the bottom of the male housing, and The provided connecting means has a connecting end for connecting to the first contact of the male housing at one end, and a connecting end for connecting to an external connected member at the other end, and a second contact provided at the other end. the second contacts are provided at the bottom of the storage cavity of the female housing at the same intervals as the arrangement spacing of the first contacts of the male housing, and one of the engaging means is arranged on the male housing. The electrical connector has an actuator member provided on an upper portion of the electrical connector and an engaging portion provided in the female housing for engaging the actuator member.

A further gist of the present invention is that, in addition to the above-mentioned requirements of the electrical connector cover, the bottom of the male housing comprises a pair of half-bottom surfaces each having a high level and a low level, and the bottom of the female housing on the storage side The electrical connector is characterized in that it consists of a pair of half-bottom surfaces having high and low levels, respectively, corresponding to the levels of the half-bottom surfaces of the male housing.

In FIG. 1, 1 indicates a male housing. As shown in FIG. 6, this male housing consists of two upper and lower housing members IA and IB.

The lower member has a semi-upper surface with two levels, upper and lower;
Contacts 8A and 8B are implanted in two rows on each half-upper surface at an arrangement pitch such that one ends thereof are staggered with respect to each other so as to protrude from the half-upper surface. One end of this protruding contact is a connection end 8JL for pressure welding.

Form 8b.

As can be seen from FIG. 4, the bottom of this lower housing member is a half-bottom surface 1 having a level difference corresponding to the half-top surface.
1 and 11B. And the contact 8A,
The other ends of 8B are bent to be exposed to the outside at the half bottom surfaces 11B and 11A, respectively. The other end of this contact contacts and electrically connects with a spring contact provided in the female housing when the male housing is inserted into and held in the female housing.

The upper member of the male housing has a cable insertion port 1 so that two overlapping flat cables 9 can be connected.
Two rows of 4A and 14B are provided.

Now, from the state shown in FIG. 6, insert the two overlapping flat cables into the cable insertion opening, and fit the upper housing member into the lower housing member 1B from the direction of the arrow shown in the figure. When the cables a and 8b pass through the through hole 1a (which also passes through the cable insertion ports i4A and 14B) drilled in the upper housing in line with the position of the pressure welding ends of the cables, the knife at the pressure welding ends of the cables The sheathing is torn 9 and the conductor of the cable is bitten into the groove at the pressure-connected end to establish an electrical connection.

Returning to FIG. 1, 13 is a member for holding the cable passing under it. Further, 4A is an actuator member, which is composed of a lever 42 and an arm 41. In the illustrated embodiment, this seven-piece worker member is the cable holding member 13.
It is pivoted to. The arm of this actuator member is connected to an engaging portion 4 provided at the upper part of the female housing shown in FIG.
This is for engaging with B. That is, when holding the male housing after inserting it into the female housing, by rotating the lever 42, the 7-mm 41 is engaged with the engaging portion 4B of the female housing.

In the case of the illustrated embodiment, the male housing is inserted diagonally into the storage cavity using guide protrusions 6 provided on the upper inner wall of the storage side 3 of the female housing as a guide. The stored male housing has a pivot shaft 5B provided at the lower part of the cylinder inner wall on the storage side and recesses 5 provided at both bottom corners of the male housing.
A is rotatably engaged. When the male housing is then rotated about the pivot axis, the guide projections 6 of the female housing engage with the steps provided on both sides of the male housing to latch the male housing into the storage cavity. Then, in order to ensure that both housings are locked together, the aforementioned 7 cutter members are operated.

As is clear from FIG. 4, the engagement hole 7 provided on the back side of the male housing on the storage side of the female housing shown in FIG. 2 is clearly visible in FIG.
A protrusion 7A is provided corresponding to B. This is also to securely hold the male and female housings together.

Next, the contacts 10A and 110B of the female housing are provided so as to penetrate from the bottom surface of the housing side to the bottom of the female housing (see FIG. 5).

The arrangement pitch corresponds to that of the contacts of the male housing. Further, the bottom surface of the storage cavity is made to correspond to that of the male housing, and if the bottom of the male housing has a level difference, a level difference is similarly provided.

As can be seen from FIG. 5, the tips of the contacts in the female housing have a substantially hook-shaped cross section. This is to provide the contact portion with the necessary elasticity to support the male housing inserted into the receiving cavity. The tips of these contacts are curved upwards as shown in FIG. 5 so that the tips of the upper contacts do not come into contact with the lower ones when they come into contact with the contacts of the male housing.

Various external ends of the contacts of the female housing can be considered depending on the manner of connection with an external connected member. The illustrated embodiment is intended for mounting on a printed circuit board.

Reference numeral 15 in FIG. 2 is a temporary fixing guide for attaching the main connector (female housing) to the printed circuit board, and is provided with a kick.

The configuration of the present invention has been described above based on the illustrated embodiments. However, the present invention is advantageous in that it is possible to connect only one flat cable without providing a level difference at the bottom of the male housing. It can also be configured with two rows (or - rows are also possible). It is also possible to mount the actuator member directly on the male housing without a cable holding member. Further, in the embodiment, the male housing is inserted obliquely into the storage cavity of the female housing, but the present invention is not limited to this.

Effects of the Invention Since the present invention has the above-described structure and provides seven actuator members in the male housing, there is no need to increase the width of the housing for mounting the actuator, and therefore the mounting area of the connector of the present invention is small. I'll try it.

Furthermore, in the connector of the invention, by providing a difference in the level at which the contacts are installed within the housing, it is possible to improve the actual density of the contacts.
