Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an electrical connection clip for electrically connecting a terminal provided on the side of an electric device or a conductor to another electric device.

[Background of the invention]

Generally, a so-called alligator clip is known as the above-mentioned clip for electrical connection. This alligator clip has a base body provided with a terminal plate on the upper surface and a movable body provided with the terminal plate on the lower surface. It has a structure in which a cord-wound spring is arranged around its shaft to constantly urge it to a closed state, a cord is connected to the above-mentioned terminal plate, and a jack or the like is provided at the end of the cord. . At the time of use, the movable body is pressed with a finger to spread it from the side of the base body, and a terminal provided in an electric device or the like is sandwiched to make a connection.

However, this work may be difficult to carry while holding it with your finger, such as when the terminal position on the electrical device side is near the housing or casing, and the connection state is simply that of the string spring. Since it was clamped by the urging force, it could easily come off.

[Purpose of device]

Therefore, the present invention has been made by paying attention to the above-mentioned problems of the conventional technology. For solving the problems, the operability is good, the handling is easy, and the connection state is strong. Intended to serve clips.

[Means for Solving the Problems]

In order to achieve this object, the clip for electrical connection according to the present invention has a terminal plate with a cord connected to the rear end on the upper surface, and an opposed standing wall formed by exposing the front of the terminal plate. And a slide member fitted between the opposing upright walls of the substrate and having a downward box portion at least at its front end, and an upward bending portion at its rear end, and a pin at the front end between the opposing upright walls of said substrate. The base end of the bent portion is pivotally supported, and the bent portion is engaged with the downward box portion of the slide member to cover the exposed portion of the terminal plate in the previous term.

[Action]

With the above-described configuration, the pivot member is opened with the slide member being slid backward, and the exposed terminal plate of the base body is brought into contact with the target terminal to move the slide member forward. Since it can be pinched by pushing work, no force is required to maintain the state in which the pivot member is opened, and connecting work is very easy by pushing the slide member,
Further, since the pivot member is pressed by the slide member, the holding force is strong and there is little risk that it will come off.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of an electrical connection clip embodying the present invention, and FIG. 2 is a sectional view showing the same connection state.

In these figures, 1 is a clip body for electrical connection configured for connecting a conductor for low frequency treatment, and the clip body 1 has a base body 2. The base 2 is made of plastic, and a metal terminal plate 3 is arranged on the upper surface thereof. Further, standing walls 4 and 4 facing each other are integrally formed on both edges along the longitudinal direction of the base body 2, and the standing walls 4 and 4 are connected at the rear end portion of the base body 2 to form a tubular portion 4a. A cord 5 joined to the terminal plate 3 in the tubular portion 4a
Is inserted, and the other end of the cord 5 is provided with an insertion portion 6 into which the jack of the device is inserted.

Further, a slide member 7 is fitted between the standing walls 4 of the base body 2, and on the upper surface of the slide member 7, protrusions 8 8 8 for assisting operation are sequentially formed with a height difference. . A stopper die 9 is formed on the lower surface of the slide member 7 near the rear end thereof.
Is to come into contact with the cylindrical portion 4a when it is moved rearward. Further, a downward box-shaped portion 10 is formed below the front end of the slide member 7.

On the other hand, reference numeral 11 in the figure denotes a pivot member, and the pivot member 11 has a bent portion 12 formed at a rear end thereof and bent upward at a substantially right angle. The bent portion 12 is a downward box-shaped portion of the slide member 7. The base end of the bent portion 12 is pivotally supported by a pin 13 between the front ends of the standing walls 4 and 4 of the base body 2. The pivot member 11 covers the exposed portion of the terminal plate 3. A tapered surface 11a is formed on the upper surface of which the front edge of the downward box-shaped portion 10 of the slide member 7 rides, and a stopper projection 14 is formed at the end of the tapered surface 11a.
Further, a terminal plate 15 is provided on the lower surface of the pivot member 11, and the terminal plate 15 has three projections 16 and 16.
... are provided in a protruding manner, and holes corresponding to the projections 16 are provided in the exposed portion of the terminal plate 3.

The clip for electrical connection of the low-frequency therapeutic conductor according to the above-mentioned embodiment is, for example, affixed on the skin of a human body on a part of the lower surface of a slightly hard conductive film such as silver chloride, and thus conductive such as potassium chloride. It is suitable for connecting a conductor coated with an adhesive gel, and as shown in FIG. 2, first, when the slide member 7 is moved backward as shown by an imaginary line, the slide member 7 is moved backward. The inner surface of the front edge of the downward box-shaped portion 10 pushes the bent portion 12 of the pivot member 11, and the pivot member 11 moves to the pin 13
Can be rotated and lifted with the fulcrum as a fulcrum. When the end portion of the conductive film A is placed on the exposed terminal plate 3 on the base body 2 and then the slide member 7 is pushed back forward, the front edge of the downward box-shaped portion 10 pushes the pivot member 11 to pivot. Moving member 1
1 covers the conductive film A, and the terminal plate 15 thereof contacts the conductive film A. Here, when the slide member 7 is further pushed forward, the front edge of the downward box-shaped portion 10 is tapered.
Ascends to a and the projections 16 are pierced and fixed to the conductive film A by the pressure, and the connection work is completed.
In addition, when removing, the slide member 7 may be pushed backward again and the pivot member 11 may be lifted.

Due to the above-described operation, the electrical connecting clip according to the present embodiment has a strong connecting force, is hard to come off, and has good operability.

[Effect of device]

As described above, according to the electrical connection clip of the present invention, work is performed by operating the slide member, and since the slide member has no biasing means such as a spring, workability and operability are improved. In addition, the connection state can be made not only to be clamped but also to be strong since pressure can be applied after the clamping.
