Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector housing that securely holds the mating of the housings of a connector and fixes the connection terminals housed in the housing. is there.

[Prior Art] Conventionally, there is no special means for fixing the connection terminals, which are respectively housed in a pair of housings, after fitting, and the connection terminals move after fitting to make the connection electrical characteristics unstable. There is a problem.

[Object of the Invention] An object of the present invention is to solve the above-mentioned drawbacks and to reliably lock the housings without rattling them by a locking member provided with a circuit element, and to connect the connection terminals in the housing. The object of the present invention is to provide a connector housing that can firmly fix the connector and realize a predetermined circuit configuration.

[Summary of the Invention] The gist of the present invention for achieving the above-mentioned object is composed of a pair of housings respectively accommodating a plurality of connection terminals each having an insertion hole. A connector housing for locking both housings by externally inserting a locking member, wherein the locking member has a circuit element interposed between a plurality of conductive rod-shaped insertion portions, The connector housing is characterized in that these insertion portions are inserted into the overlapping portion of the housing and also inserted into the insertion holes provided in the connection terminals, and the locking member is locked to the one housing. Is.

Embodiments of the Invention The present invention will be described in detail based on the illustrated embodiments.

FIG. 1 is a perspective view of the housings 1 and 2 before being fitted together, and FIG. 2 is a vertical cross-sectional view in the fitted state. The housings 1 and 2 are made of synthetic resin, the first housing 1 is a male housing, and the second housing 2 is a female housing. The housings 1 and 2 accommodate a required number, for example, two connecting terminals 3 and 4, respectively, in the embodiment, and by the locking pieces 1a and 2a provided on the housings 1 and 2 as shown in FIG. Connection portion 3a of the connection terminals 3 and 4,
The rear part of 4a is locked so that the connecting terminal 3,
4 is held so as not to slip out from the housings 1 and 2. The electric wires 5 and 6 are connected to the rear ends of the connection terminals 3 and 4, respectively.

Further, the first and second housings 1 and 2 are each provided with two windows 1b and 2b on the upper and lower surfaces, which are the same in number as the number of sets of the connection terminals 3 and 4, and the windows 1b and 2b are the first. The housing 1 and the second housing 2 are in a matched position in a fitted state. These windows 1b and 2b have housings 1 and 2
The locking member 7 is inserted when they are fitted to each other. The locking member 7 has two insertion portions 7a and 7b made of a metal body, and is made of synthetic resin and has a circuit element therein. They are connected by the base 7c. The insertion portions 7a and 7b of the locking member 7 enter the inside of the housings 1 and 2 through the window portions 1b and 2b, respectively, and further, as shown in FIG.
It is adapted to be inserted into insertion holes 3b and 4b provided in a and 4a, respectively.

Then, both ends of the base portion 7c are adapted to engage with the engagement grooves 2c of the second housing 2 in a state in which the locking member 7 is inserted and attached to the first and second housings 1 and 2. In addition,
The first housing 1 is provided with a claw portion 1c on both side surfaces thereof, and the second housing 2 is provided with a locking hole 2d into which the claw portion 1c is inserted to assist in locking the housings 1 and 2 together. I am supposed to do it.

Therefore, when the first and second housings 1 and 2 to which the connection terminals 3 and 4 are attached are fitted together as shown in FIG. 2, the connection terminal 4 fits inside the connection terminal 3 and can be energized. At the same time, the claw portion 1c of the first housing 1 is fitted into the locking hole 2d of the second housing 2 so that the housings 1 and 2 are locked together.

Then, when the lock member 7 is inserted from the outside, the insertion portions 7a and 7b of the lock member 7 are inserted into the first and second housings 1 and 2, respectively, and the connection terminals 3 and 4 are connected. Insertion hole 3
Insert b and 4b to the surface opposite to the housings 1 and 2, and lock the housings 1 and 2 together.
The connection terminals 3 and 4 will be fixed together. Therefore,
Unless the locking member 7 is pulled out, the housing 1,
The two will never be separated. The lock by the lock member 7 can be easily confirmed from the outside,
The housings 1 and 2 are locked together, and the connection terminals 3 and 4 are fixed together. In addition, the insertion portions 7a and 7b of the locking member 7
Since the circuit element is interposed therebetween, a circuit can be formed between the connection terminals as needed.

FIG. 4 shows another embodiment in which the locking member 7 is formed integrally with the first housing 2 and has a flexible hinge portion 2e.
Are connected via. When inserting the locking member 7, the hinge portion 2e may be bent and the insertion portions 7a and 7b may be inserted.
There is no risk of losing the locking member 7.

FIG. 5 shows an example in which the insertion portions 7a and 7b of the locking member 7 are integrated, and two sets of connection terminals in the housings 1 and 2 are electrically connected. Further, in FIG. 6, a circuit element 7d such as a diode is interposed between the insertion portions 7a and 7b of the locking member 7, and if necessary, a predetermined electrical operation is performed between the two sets of connection terminals. Can be done.

In the above-mentioned embodiment, it goes without saying that the locking member 7 must be pulled out in order to separate the first and second housings 1 and 2 from each other.

[Effects of the Invention] As described above, in the connector housing according to the present invention, the housings can be locked together securely, and the connection terminals can be fixed extremely firmly and without rattling. Its mechanical and electrical reliability is extremely high. In addition, various functions can be easily realized by interposing the circuit element between the connection terminals using the plurality of insertion portions.
