る。 A conventional protective cap for electric wire terminals (hereinafter simply referred to as a protective cap) consists of a bell-shaped body 1 made of a soft insulating material such as rubber, and a rear end of the body 1, as shown in Figures 1 and 2. The lower edge of the body 1 is integrally formed with an annular locking edge 3 that protrudes inward (toward the center of the body 1). The wire terminals are covered by the procedure shown in FIGS. 3A to 3C. That is, the end of the electric wire 5 and the latter half of the electric wire terminal 6 connected to the electric wire 5 are inserted into the wrapping part 2, and the body part 1 is inserted into the terminal 4 on the equipment side.
First, attach the rear end 3' of the locking edge 3 (the rear end of the trunk 1 directly below the junction of the trunk 1 and the envelope part 2),
The lower surface of the engaging portion 7 of the terminal 4 is engaged. continue,
A locking edge 3'' near the front end of the body part 1, where force is easily applied, is engaged with the lower surface of the engaging part 7, and the protective cap is covered over the terminal 4 part so that it does not easily come off.

の覆着作業性が好ましくない。 However, according to the protective cap of the conventional structure described above, the body part 1 and the locking edge 3 are formed concentrically as shown in FIG. Since the protrusion length L in both directions is equal, it becomes difficult to engage the rear end 3' portion, where it is difficult to apply force, with the engaging portion 7 of the terminal 4 during the covering, which reduces the workability of the covering. is not desirable.

本考案は、以上の従来難点を解消し、覆着作業

る。 Embodiments will be described in detail below with reference to drawings. 4 and 5 showing an embodiment thereof, the protective cap according to the present invention has a bell-shaped body 1 and a body 1.
A tubular envelope part 2 that is connected to the rear end and extends laterally.
The body part 1 and the envelope part 2 are integrally molded from a soft insulating material such as rubber, and their hollow parts communicate with each other. Then, as in the conventional structure, the end of the electric wire 5 and the latter half of the electric wire terminal 6 attached to the end of the electric wire 5 are inserted into the wrapping part 2, and the device side terminal 4 is enclosed in the body part 1. It has become like a covering.

最大***代L₁、胴部１の後端部位において最小
***代L₂になつている。 When the lower edge of the body 1 is covered, its peripheral edge is engaged with the lower surface of the engaging portion 7 of the device terminal 4, so that the protective cap can be easily separated from the device terminal 4. When the annular locking edge 8 that encloses and protects the terminal portion without any gaps faces inward, the protrusion length L
The ridge length L is unequal along the periphery, with a maximum ridge length L ₁ at the front end of the body 1 and a minimum ridge L ₂ at the rear end of the body 1. It's summery.

最小L₂の要件を充足させても良い。 That is, in the locking edge 8 of this embodiment, the center O ₂ of the inner circle 9 of the annular locking edge 8 is eccentric by an amount E from the center O ₁ of the inner circle 10 of the lower edge of the body 1. The protrusion length L of the locking edge 8 that protrudes inward from the inside of the body 1 is uneven along the circumference, and the locking edge 8 and the engaging portion 7 come into contact with each other. The total area is such that the necessary locking force is generated during the aforementioned engagement action. Note that the unequal configuration of the upheaval length L is not only due to the eccentric means described above;
The upheaval length L may be made partially the same to satisfy the requirements of the maximum L ₁ and minimum L ₂ described above.

的性能に障害を生ずることはない。 According to the protective cap constructed as described above, when covering the terminal portion on the equipment side by the procedure shown in the third figure, the protrusion of the locking edge 8' at the rear end portion of the body 1 to which it is difficult to apply force is possible. Since _L2 is the minimum, the fitting distance with the engaging portion 7 is minimized, making it extremely easy to fit. Therefore, even if the fitting margin between the locking edge 8'' at the front end portion of the body 1 and the engaging portion 7, which is easy to apply force to, becomes large, the covering work becomes easier as a whole, and the workability improves. Then, the covered protective cap generates the necessary locking force by the entire circumference of the locking edge 8, and securely wraps and protects the terminal part on the device side, thereby reducing the cap function. This will not affect the electrical performance of the part.
