Hereinafter, preferred embodiments will be described in detail with reference to the accompanying drawings.

The embodiments to be described below are intended to describe in detail enough to be easily implemented by those of ordinary skill in the art to which the present invention pertains, thereby limiting the technical spirit and scope of the present invention. doesn't mean

In addition, the size or shape of the components shown in the drawings may be exaggerated for clarity and convenience of explanation, and the terms specifically defined in consideration of the configuration and operation of the present invention may vary depending on the intention or custom of the user or operator. It should be noted that definitions of these terms should be made based on the content throughout this specification.

Among the accompanying drawings, FIG. 1 is a perspective view of a terminal coupling device for electrode connection according to an embodiment, FIG. 2 is a front view of a terminal coupling device for electrode connection according to an embodiment, FIG. 3 is an electrode connection according to an embodiment 'A-A' line cross-sectional view of the terminal coupling device, Figure 4 is a 'B-B' line cross-sectional view of the terminal coupling device for electrode connection according to the embodiment.

As shown in Figures 1 to 4, the electrode connection terminal coupling device according to the embodiment,

It has a hollow shape and has a cylindrical shape with both ends open,

Rings (100a, 100b) are formed on both sides, respectively,

The arc-shaped body 200 which is formed concave toward the middle and circumscribes the tab terminal 300 is formed.

The arc-shaped body 200 is a grate-shaped and downwardly concave arc-shaped, and a plurality of arc-shaped bodies 200 are arranged in the circumferential direction to have elasticity and are in close contact with the outer circumferential surface of the tab terminal 300 that is fitted inside While exerting a holding force, electricity can flow by contact.

The tap terminal 300 described in the description of the embodiment is defined as a rod-shaped electric plug.

If this embodiment is applied to the connector of the electric plug, it will be possible to stably maintain the electric flow,

If the present embodiment is applied to the coupling port of the signal line plug, a multi-contact structure is formed so as to stably maintain the electronic signal flow.

The arc-shaped body 200 is disposed in the circumferential direction, and a portion is cut to form a spacer 260, so that both ends are spaced apart from each other by a predetermined interval.

By forming the separation portion 260, the arc-shaped body 200 can improve the rate of expansion and contraction of compression and restoration, and function as a buffer space that can prevent fatigue failure.

A plurality of central incision grooves 220 which are perforated in the central portion of the arc-shaped body 200 and are formed to face the openings at both ends are formed at equal intervals in the circumferential direction.

In addition, it is formed between the central incision groove 220 and the central incision groove 220 formed in a plurality, and one end is close to both sides of the

ring

100a, 100b, but the side incision groove 240a is shorter than the

central incision groove

220, 240b) are respectively formed on both sides.

Preferably, the central incision groove 220 is formed in the longitudinal direction up to the intermediate position of the

side incision grooves

240a and 240b on both sides.

Accordingly, the central incision groove 220 and the

side incision grooves

240a and 240b are alternately formed.

That is, the central incision groove 220 is formed and the

side incision grooves

240a and 240b are formed next to it.

Also preferably, both side cut-out

grooves

240a and 240b are formed parallel to the central cut-out groove 220 . Of course, it should be noted that non-parallel shapes can also be implemented.

In this way, the central incision groove 220 is formed to be long, and the

side incision grooves

240a and 240b are formed to have short lengths on both sides thereof.

A portion having an area between the central incision groove 220 and the central incision groove 220 becomes an arc-shaped body 200 that is in contact with the tab terminal 300 as a counterpart, and a plurality of arc-shaped bodies 200 are formed in the circumferential direction. As such, it acts as a multi-contact point.

According to the embodiment, the arc-shaped body 200 having a large area between the two central incision grooves 220 can be formed by forming the central incision grooves 220 on both sides of the

side incision grooves

240a and 240b, respectively. Since the arc-shaped body 200 having such a large contact area is in contact with the tab terminal 300, the contact performance is improved, which is advantageous for the allowable current.

In addition, since the side cut-out

grooves

240a and 240b are respectively formed on both sides, the stress of the arc-shaped body 200 formed in the middle portion thereof can be reduced.

Although described with reference to the preferred embodiment, it will be readily recognized by those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, and all such changes and modifications fall within the scope of the appended claims. is self-evident
