にしてある。
For example, a cigarette lighter A installed in an automobile instrument panel has a rectangular arrangement in which two tab-shaped connection terminals A 1 and A 2 are orthogonal to each other, as shown in FIG.
Therefore, the housing B of the connector also has a rectangular structure in which the horizontal axis planes of the two terminal accommodating chambers 1 and 1' intersect. Moreover, as is clear from FIG. 7, the insertion opening 2, which is the front end face of each storage chamber,
2' are formed at different levels (step d), and tapered guide grooves 3, 3' are provided for the tab-type connecting terminals A 1 and A 2 to facilitate the fitting operation.

溝３′に入る案内作用も果たす。 For the mating work, insert the two terminals A 1 and A 2 into each insertion slot 2,
The correct method is to firmly insert the guide grooves 3, 3' in the insertion slots 2, 3', and then press firmly.
The step d of 2' also serves to guide when one terminal A 1 enters the guide groove 3, the other terminal A 2 enters the other guide groove 3'.

しうる構造としたことを特徴とする。Structure of the invention [Means for solving the problem] To explain with reference to the drawings, the two-pole connector housing of the invention has mating terminals A 1 and A 2 as shown in FIGS. 1 to 3. Correspondingly, the horizontal axis planes of the two terminal accommodating chambers 1 and 1' intersect and are arranged in a square shape, and the insertion openings 2 and 2' for the mating terminals A 1 and A 2 on the front end surface of each accommodating chamber are formed at different levels. Along with being
In a two-pole connector housing in which each insertion opening 2, 2' is provided with a tapered guide groove 3, 3', the insertion opening 2 Projecting walls 4, 4' are provided to protrude forward from the front end surfaces of the terminals A1 and A2 to prevent incorrect fitting, and when the mating terminal A1 or A2 is inserted into the tapered guide groove 3 or 3' It is characterized by a structure in which rotation can be prevented by engagement between the protruding wall 4' or 4 and the mating terminal A2 or A1 .
各突出壁４，４′の挿入口前端面からの突出長

きるだけ長くする。突出壁４，４′の内面にはそ
れぞれガイド溝３，３′に臨んでテーパガイド４
ａ，４a′を形成して、相手端子の挿入を一層容易
にできるようにするのが好ましい。 The protruding length of each of the protruding walls 4, 4' from the front end surface of the insertion port is made as long as possible within a range that does not interfere with connection with electrical equipment. Tapered guides 4 are provided on the inner surfaces of the protruding walls 4, 4' facing the guide grooves 3, 3', respectively.
It is preferable to form the terminals a and 4a' so that the mating terminal can be inserted more easily.
また、一方の端子収容室１または１′に相手端
子が挿入されずに嵌合するのを確実に防止するう
えで、各収容室前面の挿入口２，２′の下壁部１
ｂ，１b′に、それぞれ壁面から突き出た誤嵌合防
止用の突起５，５′を形成するのが望ましい。 In addition, in order to reliably prevent the mating terminal from being inserted into one of the terminal accommodating chambers 1 or 1', the lower wall portion of the insertion opening 2, 2' on the front surface of each accommodating chamber is
It is desirable to form protrusions 5, 5' protruding from the wall surface, respectively, on b, 1b' to prevent incorrect fitting.
第４図および第５図は本考案の２極コネクタハ
ウジングＣと相手端子A1，A2との嵌合時の状態

FIGS. 4 and 5 show the state in which the two-pole connector housing C of the present invention and mating terminals A 1 and A 2 are fitted.
即ち、コネクタハウジングＣを外挿して、相手

タハウジングＣが回るのを防止できる。同様に逆
方向Ｑの回りも起こらない。 That is, when inserting the connector housing C and inserting the mating terminals A 1 and A 2 into the respective insertion openings 2 and 2',
When only one terminal A 2 enters the insertion slot 2',
Even if the connector housing C is rotated in the P direction using this as a fulcrum, the protruding wall 4 formed protruding from the front end surface of the other insertion port 2 interferes with the remaining terminal A1 , so the connector housing C cannot be rotated. It can be prevented. Similarly, rotation in the opposite direction Q does not occur.
また、第６図に示すように、一方の端子A2を

きない。逆も同様である。 In addition, as shown in FIG. 6, with one terminal A 2 half-inserted into the insertion opening 2', the other terminal housing chamber 1 is forcibly twisted in the opposite direction R to remove the terminal A 1 and its guide groove 3. If misalignment occurs, the protrusion 5 will obstruct the insertion of the terminal A1 , making it impossible to fit it. The same is true vice versa.
更に、本考案の２極コネクタハウジングは、２

る。 Furthermore, the two-pole connector housing of the present invention has two
Since the two protruding walls 4 and 4' form guide walls of the mold, when the housing is placed over the two mating terminals A 1 and A 2 from an oblique direction, the tapered guides 4 a and 4 a' are compatible with each other. This allows for smooth fitting.
