Description

[Detailed Description of the Invention] The present invention relates to a clip used to temporarily contact and hold electrical parts, etc., and is particularly used when the connecting part is a rod-shaped protrusion such as a check pin or part of a screw.

Electrical circuit clips are commonly used to obtain temporary contact and retention when checking electrical circuits and making various electrical measurements.There are many types of electrical circuit clips, such as bagworm clips and IC clips. There is something like that. However, all of these devices were designed so that they could only perform the simple holding action of "scissing" or "biting" in order to temporarily contact and hold the object.

For this reason, in the case of conventional devices, if some external force was applied during use, they would easily come off from the object being held, often making it impossible to check electrical circuits or make electrical measurements.

The present invention has been devised in view of the above points, and an object of the present invention is to provide a clip that has significantly improved holding power for an object to be held.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 2 is an upper jaw, and 3 is a lower jaw, both of which are made of a material with excellent electrical conductivity, such as a cold-rolled steel plate, and are mutually rotatable about a pin 9 as a pivot point. These jaws 2 and 3 extend further from the pivot point to form gripping parts 2' and 3', and the outer peripheries of the gripping parts 2' and 3' are covered with an electrically insulating cover 5 made of vinyl. . 4 is a spring that biases both jaws 2 and 3 with a predetermined set pressure in the direction of closing; 6 is electrically connected to the tip of the grip part 3' on the lower jaw 3 side by soldering, screwing, etc.;
This is a lead wire that conducts electricity to the lower jaw 3.

1 is a ring serving as a locking member fixed to the side of the tip of the upper jaw 2 by soldering or brazing,
It is made by forming a cold rolled steel plate into a ring shape. The hole 1a of this ring 1 has a size (for example, about 5 mm in diameter) that allows the protrusion 7 to be held, such as a check pin or screw, to pass through the hole 1a. When the jaws 2 and 3 are open, this hole 1a is located between the jaws 2 and 3.

The clip constructed as described above is first opened between the jaws 2 and 3 by pressing the gripping parts 2' and 3' (in the state shown in FIG. Insert the object (for example, the negative terminal of an automobile ignition coil) into the hole 1a of the ring 1, and then release the pressure on the grips 2' and 3' to release the spring 4.
It is used by closing both jaws 2 and 3 with a set load of 2 and clamping the protrusion (as shown in Fig. 3).

Therefore, according to the clip of the present invention, both jaws 2 and 3
When the protruding object 7 is being held between the two, the protruding object 7 is securely held by the ring 1 forming the locking member, and in the unlikely event that an external force is applied to the lead wire 6 or the gripping parts 2' and 3'. Even if the jaws 2 and 3 are pressed together, they will not fall off the protrusion 7.

In other words, the clip of the present invention not only has the function of clamping the clip between the upper and lower jaws, but also has the function of locking the protrusion to be held by the locking member. It has an effect.

Of course, the locking member 1 does not have to be completely ring-shaped, and may have a partially open shape such as a partially open U-shape (partially open ring shape). This is convenient because the work of passing the protrusion 7 through it becomes easy.

As described above, according to the present invention, in addition to the function of clamping the object to be clamped, the clip has a locking function using the ring-shaped locking member at the tip of the clip, so that the clip has a strong grip in the direction of the clip lead wire. When tensile force or twisting of the clamping portion is applied, the above-mentioned locking function has an excellent effect of reliably preventing the clip from coming off.
