Can be attached to However, if only the above-described structure is used, the lock body 28 may come off. Therefore, in the case of the present embodiment, as shown in FIG. 2B, when the projection 44 is formed behind the partition wall 20 of the body 11 and the cover 12 to which the lock body 28 is temporarily fixed is attached to the body 11, The lower portion of the fixing piece 33 is sandwiched between the protrusion 44 and the partition 43 of the cover 12 corresponding to the partition 20 of the body 11 to lock the lock body 2.
8 is permanently fixed. That is, in the case of the present embodiment, the holding piece 32 and the fixing piece 33 serve as a fixing portion of the lock body 28, and the mounting recess 37 and the insertion hole 39 elastically connect the locking body 28 with the fixing section. Lock body 2 with uneven fitting
8 is temporarily fixed, and the partition 43 and the projection 44 function as a holding portion for holding the fixing portion of the lock body 28 when the body 11 and the cover 12 are combined.

Thus, the harness plug A is prevented from coming off. At this time, since the locking piece 42 is provided in the present embodiment, the locking piece 42 is locked to the opening edge on the front side of the hole 36, and the harness plug A is connected to the harness connector as in the related art. There is no loss of connection to B. In other words, the amount of protrusion of the claw 30 into the recess 13 is regulated by the locking piece 42, so that the claw 30 can face the recess 13 in a constant state,
For this reason, the connection portion 40 of the harness connector B is different from the conventional one.
Does not push down the claw 30 portion by the front surface, so that the harness plug A cannot be connected.

Therefore, in the present embodiment, the shape of the lock body 28 is formed in a state in which a force for elastically returning downward is exerted in the state shown in FIG. 1 (excess pressure is exerted on the tip of the lock body 28 where the claw 30 is formed). The locking piece 42 is brought into close contact with the opening edge of the hole 36 of the cover 12. Moreover, when the locking piece 42 is brought into close contact with the opening edge of the hole 36 of the cover 12 in this manner, the amount of hook between the concave streak 41 and the claw 30 becomes constant, and the connection between the harness plug A and the harness connector B is ensured. Can be retained. In the case of this embodiment, the opening edge of the hole 36 of the cover 12 in which the locking piece 42 is locked is recessed to prevent the locking piece 42 from protruding to improve the appearance.

方にハーネスプラグＡを取り付ければよい。When the harness plug A is detached from the harness connector B, when the rear end of the lock body 28 is pushed into the recess 38, the lock body 28 rotates about the base end of the elastic piece 32 as a fulcrum. The locking state of the claw 30 with the concave streak 41 is released. At this time, the harness plug A can be detached from the harness connector B by pulling the harness plug A backward. This kind of harness plug A is used, for example, in the following floor wiring system. In this floor wiring system, as shown in FIG. 4, floors are formed at regular intervals on a slab of a building, and floor wiring is performed using a space between the slab and the floor, so-called free access. This is called a floor. In this free access floor, a plurality of outlets C are buried on the floor, and wiring appliances H and I such as a plurality of outlets are placed on the floor.
Place. Here, the power cords of the wiring devices H and I are drawn under the floor in the demarcation box D. The outlet C and wiring accessories H, the tip of the power cord I is attached to the harness plug A according to the present embodiment, the jointers B 'for further branching the branch circuit that branches the trunk L 0 in the joint box J Connect the harness plug A,

It has a plurality of connecting portions 40 having the same structure as in FIG. When simply connecting the power supply line to the wiring devices H and I or extending the power supply line, the harness connector B may be attached to the power supply side, and the harness plug A may be attached to the other end.

The state of protrusion into the recess becomes constant, and the claw portion of the lock body is caught between the front surface of the connection portion and the inner surface of the recess in the insertion direction of the connection portion, so that the harness plug cannot be connected to the harness connector. Connection can be made well, and the locking piece is elastically locked to the opening edge of the hole formed in the housing. Thus, it is elastically engaged with the concave streak of the connection portion, and can be reliably prevented from falling off.

When the body and the cover are combined with each other and the holding portion for holding the fixing portion of the lock body is formed on the body and the cover, the cover and the body are temporarily fixed by fitting the lock body into and out of the housing. When the lock body is combined, the lock body is permanently fixed, so that troublesome operations such as welding and bonding are not required, and the lock body can be easily fixed.
