本考案は、相手タブとの間に錠止機構を有する
雌端子と、これを収容するハウジングとから構成
されるコネクタの解錠構造の改良に関する。[Detailed description of the invention] [Field of industrial application] The present invention is an improvement in the unlocking structure of a connector that is composed of a female terminal having a locking mechanism between it and a mating tab, and a housing that accommodates the female terminal. Regarding.

Japanese Patent Publication No. 55-42467 discloses a housing that accommodates a female terminal having a locking mechanism between it and a mating tab, in which a flexible arm is provided on the wall of the housing, and by pushing down the arm, the female terminal can be opened. A device is disclosed in which a tongue piece (elastic contact piece) is pushed down and separated from a mating tab.

の解錠アームｆが形成されている。 To explain this in detail with reference to the drawings, in Fig. 5, a is a female terminal, the free end c of the tongue piece b thereof extends beyond the rear end of the receiver part d relative to the mating tab, and the terminal The housing e is bent to protrude higher than the height H 1 to form a release member c, and the housing e is formed with a flexible unlocking arm f for the release member c.

コストが高くなるという問題があつた。 According to the above structure, since the unlocking arm f is formed to protrude one step higher than the upper wall h of the terminal storage chamber g, when it is hooked on an electric wire or the like and bends upward, the release member c is exposed. There was a risk of insulation failure or short-circuiting.
In addition, when assembling a wire harness, there is a step in which the worker takes out the necessary wires W one by one from the bundle W of wires with female terminals A attached, as shown in Figure 6. There was a drawback that the protruding portions c became tangled with each other, resulting in poor workability. On the other hand, Japanese Patent Application Laid-Open No. 18097/1983 proposes a female terminal with an improved release part, but this is because the unlocking arm f is formed to protrude inside the housing. There were problems in that the molding die was extremely complicated, resulting in an enlarged housing and increased manufacturing costs.

とする。[Means for Solving the Problems] In order to achieve the above object, the present invention has a locking mechanism between the mating tab and a release member for controlling the locked state of the female terminal by locking the connector housing. In the connector, the locking/unlocking arm is pushed down and the release member is pushed down to unlock the connector, wherein the locking/unlocking arm is formed separately from the housing and is inserted into the housing. The locking arm is formed integrally with a member having a second locking mechanism that prevents the female terminal from coming off, and the unlocking arm faces the release member when the member is inserted into the housing. Features.

As shown in FIG. 3, the female terminal 1 is connected to the substrate portion 1a
The free edges of the upstanding side walls 1b on both sides are bent above the base plate part 1a, and these bent parts are further bent towards the base plate part 1'a side to form a receiving part 1c for the mating tab together with the base plate part 1a. Ru. A folded elastic tongue piece 1d is formed from the base plate part 1a at the tab entrance part of the base plate part 1a, and the elastic tongue piece 1d
A locking piece 1e that engages with the corresponding hole or recess of the mating tab is cut and raised in the middle part of the mating tab, and the free edge 1f of the elastic tongue piece 1d extends from the base plate inside the rear part of the receiving part 1c. It is bent away so as to form a release member 1f. The height H 3 of the release member 1f is the height H 2 of the receiving portion 1c and H 3 ≦
It is formed to satisfy the relationship H 2 . Also,
A locking hole 1g that engages with locking pieces 5a and 5a' constituting a first locking mechanism, which will be described later, is formed in the base plate portion 1a.

あり、安価に製造することができる。 As is clear from this example, in the connector of the present invention, the locking and unlocking arm of the female terminal is formed separately from the housing (main body), so the internal structure of the housing is the locking mechanism with the mating tab. There are no changes other than the normal housing and the cutout, and it is easy to manufacture. The cover with the locking/unlocking arm and the second stopper piece projecting thereon also has a simple structure and can be manufactured at low cost.
