Abstract

PURPOSE:To surely lock housings each other and also strongly fix connection terminals in the housings each other by providing the housings with a locking member for locking the housings each other by inserting the locking member from the outside of the housings and fix the connection terminals each other by inserting the locking member into inserting openings provided in the connection terminals. CONSTITUTION:When the first and second housings 1 and 2 attached with connection terminals 3 and 4 are made in insertion relation, the connection terminal 4 is inserted into the connection terminal 3 to be in electrically connectable state and also a claw member 1c of the first housing 1 is hooked with a hooking opening 2d of the second housing 2 to lock the housings 1 and 2 each other. Furthermore, when a locking member 7 is inserted into the housings 1 and 2 from the outside, leg portions 7a and 7b of the locking member 7 are inserted into the housings 1 and 2, respectively and also inserted into inserting openings 3b and 4b of the connection terminals 3 and 4 to reach the opposite sides of the housings 1 and 2 to lock the housings 1 and 2. Accordingly, the connection terminals 3 and 4 are strongly fixed to each other and its reliability is improved.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a connector housing that reliably maintains the fitting of connector housings together and also fixes connecting terminals housed within the housing. be.

[Prior art] Conventionally, there is no special means for fixing the connecting terminals housed in a pair of housings after they are mated, and the connecting terminals move after mating, making the electrical characteristics of the connection unstable. There is a problem.

[Object of the Invention] An object of the present invention is to eliminate the above-mentioned drawbacks, and to provide a connector housing that can reliably lock the housings together without rattling and firmly fix the connection terminals in the housing. It's about doing.

[Summary of the Invention 1 The gist of the present invention for achieving the above-mentioned object is to consist of a pair of housings each accommodating a connecting terminal, and when the two housings are fitted together, the housings are inserted from the outside of the two housings to This connector housing is characterized in that it includes a bar-shaped locking member that locks and locks both housings together and that is inserted into an insertion hole provided in the connection terminal to fix the connection terminals together.

[Embodiments of the invention] The present invention will be explained in detail based on illustrated embodiments.

FIG. 1 is a perspective view of the housing 1.2 before they are fitted together, and FIG. 2 is a longitudinal cross-sectional view of the housings 1 and 2 in the fitted state. The housings 1.2 are molded from synthetic resin, the first housing 1 being a male housing and the second housing 2 being a female housing. A required number of connection terminals 3, 4, for example, two in the embodiment, are housed in the housings 1, 2, respectively, and are connected by locking pieces 1a, 2a provided on the housing 1.2, as shown in FIG. The rear portions of the connecting portions 3a, 4a of the connecting terminal 3.4 are locked, and the connecting terminal 3.4 is held so that it cannot be pulled out from the housings 1, 2, especially when mated. Note that electric wires 5.6 are connected to the rear ends of the connection terminals 3.4, respectively. Also, 1st. The second housings l and 2 both have window portions 1b and 2b on the upper and lower surfaces.
The same number of connection terminals 3.4 as the number of pairs of connection terminals 3.4 are provided, and the window portions tb and 2b are positioned to match when the first housing 1 and the second housing 2 are fitted together. A locking member 7 is inserted into these windows 1b and 2b when the housings 1 and 2 are fitted together,
The lock member 7 includes, for example, two insert portions 7a made of a metal body,
7b, and are connected by a base 7C made of synthetic resin.

The insertion parts 7a and 7b of the locking member 7 each have a window part tb,
2b into the interior of the housing 1.2, and then the third
As shown in the figure, the connecting terminals 3.4 are inserted into insertion holes 3b and 4b provided in the connecting portions 3a and 4a, respectively. Then, the locking member 7 is connected to the first locking member 7. When inserted into the second housing 2, both ends of the base 7c are engaged with the retaining grooves 2C of the second housing 2. Note that the first housing l is provided with claws 1c on both sides, and the second housing 2 is provided with a locking hole 2d into which the claws 1c enter, to assist in locking the housings 1 and 2 together. It is designed to be carried out in a specific manner.

Therefore, when the first and second housings 1.2 each having a connecting terminal 3.4 attached thereto are fitted together as shown in FIG. At the same time, the claw portion 1c of the first housing 1 fits into the locking hole 2d of the second housing 2, and the housing 1.2
Comrade's locking is done auxiliary. When the locking member 7 is inserted from the outside, the insertion portions 7a, 7 of the locking member 7
b are inserted into the first and second housings l and 2, respectively, and further passed through the insertion holes 3b and 4b of the connection terminals 3.4 to the opposite surface of the housings l and 2, and then inserted into the housing 1. .2 In addition to locking the comrades, the connection terminal 3.4
We will be fixing our comrades. Therefore, unless the first locking member 7 is removed, the housings 1 and 2 will not be accidentally separated. Note that locking by this locking member 7 can be easily confirmed from the outside, and the housing 1,
The locking of the two terminals and the fixing of the connecting terminals 3 and 4 are ensured.

FIG. 4 shows another embodiment, in which the locking member 7 is integrally formed with the first housing 2 and has a flexible hinge portion 2.
When inserting the 0-lock 1F member 7 connected via e, it is sufficient to bend the hinge portion 2e and insert the insertion portions 7a and 7b, eliminating the risk of losing the locking member 7.

In FIG. 5, the insertion parts 7a and 7b of the locking member 7 are integrated,
An example is shown in which the housing 1.2 is made of a conductive material, so that the two sets of connection terminals in the housing 1.2 are electrically connected. Further, in FIG. 6, a circuit element 7C such as a diode is interposed between the insertion portions 7a and 7b of the locking member 7, and two
A predetermined electrical operation can be performed between the set of connection terminals.

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

[Effects of the Invention] As explained above, the connector housing according to the present invention securely locks the housings together, and also fixes the connecting terminals together extremely firmly without play. Its mechanical and electrical reliability is extremely high, and since circuit elements can be interposed between the connection terminals using a plurality of insertion parts, various functions can be easily realized.
