る。[Detailed description of the invention] Purpose of the invention [Field of industrial application] The present invention relates to a connector for connecting an electric circuit, and in particular, the present invention aims to miniaturize the connector by improving the terminal locking structure in the terminal housing chamber. This is what I did.
電気接続用端子をハウジング内の端子収容室内

ようにしたコネクタは公知である。
The electrical connection terminal is inserted from the rear into the terminal accommodating chamber in the housing, and the forward movement of the terminal is stopped by a stopper provided near the front end of the terminal accommodating chamber, and the terminal is provided diagonally protruding forward from the side wall surface of the terminal accommodating chamber. Connectors are known in which terminal retraction is prevented by flexible terminal locking arms.

などの故障を生ずることがあつた。 Although connectors have the advantage of being simple in structure and easy to assemble, it is not easy to check whether the terminals are inserted sufficiently, and some parts are not fully engaged during assembly. As a result, failures such as terminals falling off may occur after assembly into devices.
そこで、米国特許第3601760号には、第５図に

ストが嵩むという問題が残されていた。 However, in this case, since the flexure space S for the locking arm d is provided separately from the spaces for the terminal accommodating chambers b and b', the size of the insulating housing a is unavoidable, and the Separate parts are required, and the problem remains that the cost increases due to an increase in the number of parts and the number of man-hours for assembling them.
このようなわけで、本考案はスペーサのような

うに構成されていることを特徴とする。 Structure of the Invention [Means for Solving Problems] To explain with reference to the drawings, the present invention has partition walls 1a, 1b, . . . as shown in FIGS. 1 to 4.
A plurality of terminal storage chambers 2a, 2b partitioned by
... in parallel, and a terminal T that can be locked by flexible locking arms 3a, 3b provided on a part of the partition wall, the locking arm 3a , 3b... have locking steps 4a, 4b on the front side that engage with the terminals T in the accommodation chamber.

Since it is formed by providing two slits 5 parallel to the axial direction of the storage chamber, both upper and lower surfaces are flush with the partition walls 1a, 1b, etc., and the cut end of the slit 5 is the fulcrum. It's starting to bend. Each locking arm 3a, 3b... is connected to its front side (in the figure, each accommodation chamber side 2a, 2b...
side) are provided with locking step portions 4a, 4b, . . . that engage with the rear end portion of the receiving portion T1 of the terminal T.

止めるストツパである。 In the figure, there are two terminal accommodating chambers 2a and 2c on the outermost side of the insulating housing H.
Since there is no terminal accommodating chamber adjacent to the lowermost terminal accommodating chamber 2c, it is preferable to provide a space S' in this portion for the locking arm 3c to temporarily bend. The other (top) terminal housing chamber 2
The locking arm 3a of a is unnecessary because the adjacent storage chamber 2b also serves as a bending space. 6 is a stopper that stops the terminal from moving forward.

As shown in FIG. 4, when the terminal T is inserted from the rear of the uppermost terminal accommodating chamber 2a in the insulating housing H, its receiving portion T1 comes into contact with the rear taper 4a1 of the locking step portion 4a and is engaged. When the stop arm 3a is bent downward (to the side of the adjacent storage chamber 2b) and entered (state A), and further advanced and climbed over the stepped portion 4a,
The locking arm 3a elastically returns to the storage chamber 2a side, the locking step portion 4a engages with the rear end of the receiving portion T1 , and the front end of the receiving portion T1 is stopped from advancing by the stopper 6. Thus, the terminal T is locked in the housing chamber 2a.
以下、同様にして上から順に収容室２ｂ，２ｃ
に端子を挿入、係止する（第３図）。 Thereafter, in the same manner, the accommodation chambers 2b and 2c are sequentially placed from the top.
Insert and lock the terminal in (Figure 3).

スペーサを使用する必要もなくなる。 In this way, by sharing the temporary space of the locking arm 3a with the storage chamber 2b, incomplete insertion of the terminal can be easily confirmed and prevented. By replacing the flexing space of the locking arm with the adjacent storage chamber, the flexing space S (see Fig. 5) dedicated to the locking arm, as in the past, is no longer necessary, so the insulating housing H can be reduced by that amount. In addition to being downsized, the locked terminals mutually prevent the locking arm from deflecting.
There is no need to use a spacer.

ネクタの小型化に役立つ。 Effects of the Invention As explained above, in the multi-pin connector of the present invention, the flexible locking arm that locks the terminal shares a space with the adjacent terminal accommodating chamber for temporarily bending when the terminal is inserted. Separate parts such as conventional spacers are no longer required, reducing the number of parts and assembly man-hours, contributing to cost reduction, as well as preventing incomplete insertion of terminals, ensuring secure locking, and reducing the size of the connector.
