Description

[Detailed description of the invention] "Industrial application field" This invention is compressed and contracted by the locking claws on the edge of the locking window when inserted into the space of the locking window provided on the mounting board. The present invention relates to a clamp configured to lock the locking wings to the locking window by expanding the locking wings after the locking blades are inserted through the space of the locking window.

"Prior art and its problems" Conventionally, a clamp as shown in FIG. Stop wing 3'
is locked in the locking window by the locking claw, and when a force as shown by arrow F1 is applied to the wire harness W to which the clamp is attached, the locking wing 3
Since a force as indicated by F2 is applied to the clamp, there have been problems such as the connecting portion C connecting the locking wing 3 and the support portion 4' breaking or the clamp coming off from the locking window.

``Means for Solving the Problems'' The present invention achieves the above-mentioned object. After being compressed and reduced in diameter by the locking claws 2 on both sides of the window, the locking wings 3, which elastically restore and expand after passing through the space of the locking window, expand. In a clamp configured to lock a locking wing to the locking window, an upper clamping piece 5 is provided on the upper surface of the support part 4 that supports the locking wing, and a lower part is provided on the lower surface of the support part. Clamping piece 6
The solution is to provide a structure in which the locking column is held between the two holding pieces.

"First Embodiment" Hereinafter, an embodiment of the present invention shown in FIGS. 1 and 2 will be described. The locking pawl 2 shown in FIG. 1 is provided facing the tips of a pair of locking posts 1 implanted in the mounting board 7, and has a locking window between both of the locking pawls 2. ing. Although the wire harness that is locked to this locking post 1 is not shown, it is tied together with an upper clamping piece 5 that is integrated with the clamp using adhesive tape or the like. This wire harness is assembled into an electrical circuit in advance and attached to the inner wall of the electrical equipment in order to provide electrical wiring between the electrical parts of the electrical equipment.

The clamp of this embodiment is integrally molded by injection molding, and at the tip of the support part 4, locking wings 3 connected by a connecting part made of a thin plate and having improved flexibility are provided on both sides in the shape of an arrowhead. It is being Since there is a gap between the upper surface of these locking wings 3 and the lower surface of the upper holding piece 5, the structure is such that the diameter of the locking blades can be reduced, that is, the opening angle can be made acute.

Therefore, when trying to insert the tip of the locking blade 3 into the locking window 2, the opening angle of the locking blade is made acute and the diameter is reduced by the compression of both slopes of the locking blade 3, and the insertion is prevented. After that, it elastically restores itself and expands, and the opening angle becomes obtuse. The base of the support part 4 is slightly raised and connected to the lower surface of the upper clamping piece 5. The upper clamping piece may be flat, but
To save material, ribs 8 are provided along the entire length along the edges. Also, from the lower surface of both sides of the upper clamping piece, the legs 9
hangs down, and its tips are bent in opposite directions to form a lower clamping piece 6. The distance between these legs 9 and the support part 4 is equal, and
The inner surface spacing between the legs 9 is selected to be slightly larger than the outer surface spacing L of the locking posts. Further, the distance between the lower surface of the upper clamping piece 5 and the upper surface of the lower clamping piece 6 is selected to be larger than the vertical thickness of the locking column 1. Therefore, after the clamp is locked to the locking window, it will involuntarily move in the vertical and horizontal directions (left and right directions in Figure 1).
This prevents them from moving.

“Second Embodiment” This embodiment differs from the first embodiment in that the lower clamping piece 6 is directly provided on the support portion 4. The upper clamping piece 5 and the lower clamping piece 6 in FIG. When inserted into a space, the effect of vertical guidance with respect to the support column 1 is increased.
