下をきたすおそれがあつた。(Problem to be solved by the invention) However, in the case of the former housing A', in order to double-lock the terminal T in the housing, a rear holder d made of a separate member is required, and the assembly operation is difficult. In addition to being complicated, there are also problems such as troublesome parts management and high costs. On the other hand, in the case of the latter housing A'', the rear part a1 ' of the housing outer wall for doubly locking the terminal T is formed integrally with the housing body a' via the hinge h, so parts management is difficult. Although it is not complicated in terms of, it requires a secondary operation to perform double locking after the terminal T is first locked in the housing body a',
The complexity of assembly operations cannot necessarily be resolved. or,
In both cases, the double locking state of the terminal cannot be visually confirmed, and therefore, especially in the case of a multi-pole housing, incomplete insertion of the terminal may not be noticed, leading to a risk of deterioration in the reliability of terminal locking.

It is an object of the present invention to provide a housing that can prevent incomplete insertion by allowing the locking state to be visually confirmed.
（問題点を解決するための手段）
以下に本考案を、実施例を示す図面に基づいて
詳細に説明する。(Means for Solving the Problems) The present invention will be described in detail below based on drawings showing embodiments.

後部５ａに端子係止突起６並びに電線押え突起７
をそれぞれ対向して形成した構成を有する。 In the figure, a housing A of the present invention has a wall 1 facing a terminal locking arm 3 protruding into a terminal accommodating chamber 2, which is slanted outward from the vicinity of the center in the terminal insertion direction toward the rear. A terminal insertion opening 4 is provided at the rear end 1b of the wall 1a that extends, and a terminal locking projection 6 and a wire holding projection 7 are provided at the rear portion 5a of the side wall 5 in a direction perpendicular to the wall 1.
It has a configuration in which these are formed facing each other.

に形成される。 Further, the terminal locking protrusions 6 are each formed in a plate shape on the opposing inner wall surfaces of the rear side wall 5a, and the position of the front end surface 6a facing the terminal accommodating chamber 2 is such that the terminal locking projections 6 are properly inserted into the terminal accommodating chamber 2. The rear end portion of the attached terminal T, for example, the rear end portion of the wire insulation coating crimping portion 8, is formed so that it can be locked, and the opposing interval of the terminal locking protrusions 6 is set so that the rear end portion of the wire insulation coating crimping portion 8 of the terminal T can be locked. It is formed to be slightly smaller than the width of the tightening part 8.

It is formed so that it can be inserted into the space 9 between 6 and 6. Further, it is desirable to provide the upper surface of the wire holding projection 7 with a taper 7b that is inclined downward toward the end surface 7a.

(in the direction of the arrow in FIG. 1), and at the same time push the wire insulation coating crimping portion 8 into the front end surface 6a of the opposing terminal locking projection 6. Also, electric wire W
is pushed into the space 9 through the gap between the opposing end surfaces 7a of the wire holding projection 7.

により認できるので確実に行なうことができる。 Through the above operations, the terminal T is attached to the locking hole 1 provided in the base plate of the electrical contact section 10, as shown in FIG.
0a is primarily locked to the locking protrusion 3a of the terminal locking arm 3, and at the same time, the rear end portion of the wire insulation coating crimp portion 8 is locked to the front end surface 6a of the terminal locking protrusion 6. A double lock to housing A is achieved. Since this double locking can be visually recognized from the terminal insertion opening 4, it can be performed reliably.

み合いが防止される。 Further, the electric wire W connected to the terminal T is held down by the electric wire holding protrusion 7 in the space 9 between the terminal locking protrusions 6, and its movement in the direction perpendicular to the electric wire axis direction is restricted, and its movement in the same direction is restricted. The external force load is reduced and the electric wires drawn out from the housing A are prevented from becoming entangled with each other.

利点が得られる。(Effects of the invention) Since the housing of the invention is as explained in detail above, it is possible to easily double lock the terminal to the housing by only the primary terminal insertion operation, which is different from the conventional housing. In this way, there is no need for a secondary operation of performing double locking after the terminal is first locked, and work efficiency can be significantly improved. In addition, since the locking status of the terminal can be visually checked, incomplete insertion can be completely prevented.Furthermore, there is no need for separate parts for double locking, such as a rear holder, so parts management is not complicated and costs are reduced. This provides advantages such as being able to reduce the amount of water used.
