Description

[Detailed description of the invention] (Field of industrial application) The present invention is a locking device that locks the male and female bodies of an electrical equipment connector used to connect a computer main body and an interface, etc. to prevent them from coming off. This is a fastener that can be easily locked and released in a narrow space.

(Prior art) As shown in FIG.
1 and E2 are locked to a locking holder F attached to the male body D to prevent the male body D from coming off the female body C.

The male body D in Fig. 5 is designed so that the cord G can be attached from the lateral direction (orthogonal to the insertion direction of the male body), and therefore the cord insertion part H is protruded to the side in the longitudinal direction. . Therefore, the locking tool E1 on the cord side is as shown in Fig. 5 A and B.
When the distal end I is bent laterally into an L-shape and engaged with the locking holder F, the distal end I does not come into contact with the cord insertion part H as shown in FIG. 5B.

However, in the case of the one in Figure 5, the female body C protrudes outward from the back of electrical equipment A, so when installing electrical equipment A in the place where it will be used, the back of electrical equipment A must be moved that much further away from the wall. However, there is a problem in that indoor space is wasted accordingly.

Therefore, recently, as shown in Fig. 6, a part of the back side of electrical equipment A is lowered to form a mounting part J, and a female body C is attached thereto, which is attached to the main body of the equipment A.
It is designed so that it does not protrude from the back of the

(Problem to be solved by the invention) However, in this way, with the conventional locking tool E1 bent in an L-shape, when it is tilted outward as shown in FIG. There was a problem in that the locking tool E1 did not come off completely from the locking receiver F because it contacted the peripheral wall K of the attachment part J and did not fall any further, and the locking of the locking tool E1 was not completely released.

To overcome this problem, the mounting portion J can be made wider, but if this is done, it will take up more space, making it difficult to downsize the device body A.

(Means for Solving the Problems) Therefore, the connector locking tool of the present invention is designed to allow easy locking and release even in a narrow space.

As shown in FIG. 1, the connector locking tool 1 of the present invention has a mounting part 2 that bends a wire rod and attaches it to either the male body D or the female body C so as to be rotatable, and both bodies D and C. A locking portion 3 that is locked to the other locking receiving portion F, an operating portion 4 that locks and releases the locking portion 3, and a connecting portion 5 that connects both operating portions 4 are formed. The attachment part 2 is formed by expanding both ends of the wire outward, the locking part 3 is formed by narrowing the upper part of the attachment part 2 inward to provide elasticity, and the operating part 4 is formed by expanding the ends of the wire rod outward. The locking portion 3 is formed so as to be located on the outside of both sides 6 and 7 of the cord insertion portion H when the upper part is expanded outward and the locking portion 3 is locked in the locking receiver F, and the connecting portion 5 is located at the tip of the operating portion 4. is folded back toward the locking part 3 side so that the locking part 3 is located under the cord insertion part H when the locking part 3 is locked in the locking receiving part F.

(Function) This connector locking tool 1 is used in place of the conventional locking tool as shown in FIG.

In this case, since the operating part 4 is spread out on both sides so as to be located on the outside of both sides 6 and 7 in the width direction of the male body D, it is latched to the latching holder F as shown in FIG. In this case, the operating part 4 is securely locked to the locking holder F without hitting the cord insertion part H of the male body D. Even when releasing the lock, since the operating part 4 is not bent toward the cord G side, the tip of the operating part 4 does not hit the peripheral wall K of the mounting part J, and can be surely removed as shown in FIG.

(Effects of the invention) The connector locking tool of the invention has the following effects.

(1) Since the operating part 4 of the locking tool is spread out on both sides so as to be located on the outside of both sides 6 and 7 in the width direction of the male body D, it is difficult to lock the locking tool F and release it. It can be carried out reliably in narrow spaces.

(2) It is suitable for use in a narrow space, especially in a mounting part J as shown in Fig. 3, where the part is formed one step lower than other parts.

(3) Since it can be locked and released in a narrow place, the space for attaching the male body D or the female body C to the device main body A is small, and therefore the device main body A can be miniaturized.

(4) Since the operating part 4 of the locking tool is spread out on both sides of the male body D on the outside of both sides 6 and 7 in the width direction, the cord G can be attached from the side as shown in Fig. 3. Male body D or female body C
Suitable for locking.

(5) The locking holder F for the male body D or the female body C can be a conventional one, so it is versatile and easy to put into practical use.
