According to the present invention, an elastic material is added to the outside of the fork pin to have repulsive power to prevent a coupling force from being weakened due to even a change of a vibration condition, a temperature condition and the like after the fork pin is coupled, thereby preventing a problem such as a product operation defect and the like.

Description

Fork pin for connecting terminal}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a terminal connecting fork pin, and more particularly to a terminal connecting fork pin having improved fastening force.

In general, a terminal is a part electrically connected to various external devices, and is provided inside a joint box, a fuse box, a junction box, etc. used in a car. A plurality of terminals are provided inside the joint box, the fuse box, the junction box, and the like, and are electrically connected to the tab terminals provided in the relay, the fuse, and the like. Accordingly, it is possible to prevent an overcurrent from flowing to various electric devices provided in the vehicle.

Normally, a fork pin is formed by cutting a plate-like metal to form a terminal portion and a slit therebetween, and a terminal such as a tap terminal can be inserted into the slit portion. Since the terminal portion is substantially the same as a fork, It says. Korean Patent Laid-Open Publication No. 2009-0098475 discloses a shape of a fork pin that is conventional.

However, in such a conventional fork pin, when a force greater than the elastic force of the supporting piece supporting both sides of the terminal is applied in the state where the terminal is inserted, or when vibration occurs due to an external force or a force greater than the clamping force, . Therefore, a new form of fork pin is needed to solve this problem.

Korean Patent Publication No. 2009-0098475 (published on September 17, 2009)

An object of the present invention is to provide a fork pin for terminal connection improved in fastening force.

A terminal connecting fork pin according to the present invention includes a pin body having a slit into which a terminal is inserted, a pin support portion to which the pin body is inserted and supported, and an elastic member inserted between the pin body and the pin support portion, As shown in Fig.

The pin body may include a pair of support pieces spaced apart from each other to form the slit and into which the terminal is inserted, and a contact portion protruding from one end of the support piece and contacting the terminal.

And the slit is characterized in that a distance between the contact portions corresponds to a thickness of the terminal.

And the slit gradually narrows from the lower side of the contact portion toward the lower portion of the pin body.

The pin support portion may include an insertion portion into which a part of the pin body is inserted, and a support wall extending to one side of the insertion portion and covering the support piece, the support wall being spaced apart from the support piece.

And the support wall is spaced apart from the support piece in a direction in which the support piece is deformed when the terminal is inserted.

And the resilient supporting portion is inserted between the supporting wall and the supporting piece.

And the resilient supporting portion provides a repulsive force in a direction opposite to a direction in which the supporting piece is deformed when the terminal is inserted.

And the resilient supporting portion is configured to surround a part of the supporting piece.

The support wall may include an open portion corresponding to the position of the slit.

The terminal connecting fork pin according to an embodiment of the present invention may be provided with an elastic material to the outside of the fork pin to have a repulsive force so that the fastening force can be prevented from being weakened even when the fork pin is subjected to a change in vibration, It is possible to prevent problems such as malfunction of the product.

Hereinafter, a terminal connecting fork pin according to an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view illustrating a fork pin according to an embodiment of the present invention. FIG. 2 is a plan view illustrating a fork pin according to an embodiment of the present invention. Sectional view showing a connection state of a pin and a terminal.

1 and 2, a fork pin 100 according to an embodiment of the present invention includes a pin body 110 having a slit 114 into which a terminal 200 is inserted, And an elastic supporter 150 interposed between the pin body 110 and the pin supporter 130 to provide an elastic force to the pin body 110. [

In electric parts such as EPS (Power pack), EPB, etc., motor and ECU are assembled. In order to make electrical connection when assembling various parts, connect the two parts through welding process or use the mass-production connector manufactured by the connector manufacturer.

However, the welding process is limited because of the structure of parts that can be welded and the structure that does not, which causes the increase in cost due to addition of welding processes.

In addition, when a mass-production connector is used, it is possible to directly connect the components, thereby facilitating the connection between the components and ensuring the product performance. However, there is a problem that the product structure can not be used in a product structure in which the mass-

The pin body 110 is formed with a support piece 112 spaced apart from each other by machining a metal plate at one end thereof and the other end is inserted into the pin support portion 130 at a predetermined depth and supported. The spaced apart portion of the support piece 112 corresponds to the slit 114 described above, and the terminal 200 is inserted into the slit 114.

Each support piece 112 has a contact portion 112a which is in contact with both surfaces of the terminal 200 and the contact portion 112a is formed in a circular shape protruding toward the terminal 200. [ However, the contact portion 112a is an approximate circle rather than a complete circle, and a surface contacting the terminal 200 is formed flat to improve the contact force with the terminal 200. [

The slit 114 is connected from the upper end of the support piece 112 to the portion where the pin body 110 is inserted into the pin support portion 130. The slit 114 has the narrowest width between the contact portions 112a, The width again widen. Further, the slit 114 is gradually narrowed toward the bottom of the pin body 110. When the shape of the slit 114 is gradually narrowed toward the bottom of the pin body 110, the width of the support piece 112 increases toward the bottom of the pin body 110. Therefore, even if the support piece 112 is extended by the insertion of the terminal 200, the width of the support piece 112 increases toward the lower portion of the support piece 112, so that the repulsive force against deformation increases and the fastening force can be improved.

The pin supporting portion 130 includes an insertion portion 132 into which the pin body 110 is inserted and a supporting wall 134 extending upward from the insertion portion 132 to cover the remaining portion except for a part of the end portion of the supporting piece 112 And an elastic supporting part 150 inserted between the insertion part 132 and the supporting wall 134. [

The pin supporting portion 130 has a tetrahedron shape and supports the pin body 110 in a state where the pin body 110 is inserted to a predetermined depth on one surface. A support wall 134 is formed along one edge of the pin support 130 where the pin body 110 is inserted.

The support wall 134 is formed to have a length covering the remaining part except the part of the support piece 112, and is formed to be spaced apart from the support piece 112 by a predetermined distance. An opening 134a is formed in the support wall 134 in correspondence with the position of the slit 114 and the opening 134a is aligned with the slit 114. [ That is, the support wall 134 has a shape in which the terminal 200 is inserted between the support pieces 112 to cover the direction in which the support pieces 112 are extended.

The elastic supporting portion 150 is inserted between the supporting wall 134 and the supporting piece 112 in the form of a block having a predetermined thickness and elastically presses the supporting piece 112. The resilient supporting portion 150 has an elastic force and thus acts to provide a repulsive force to the supporting piece 112 when the supporting piece 112 is deformed to the outside (see arrow direction). To this end, the resilient support portion 150 preferably has a length sufficient to support at least 50% of the length of the support piece 112.

2 and 3, the elastic supporting part 150 may be inserted into the outer side of the supporting piece 112 in a direction in which the supporting piece 112 is deformed, or may be formed to surround the supporting piece 112. [

4 is a plan view showing a fork pin according to another embodiment of the present invention (for the sake of simplicity, detailed description of the same configuration as that of the above-described embodiment will be omitted).

4, the fork pin 100 'according to another embodiment of the present invention is configured such that the elastic support 150' is inserted between the support piece 112 and the support wall 134 in a block form, And is inserted outside the direction in which the piece 112 is deformed. Further, the elastic supporting portion 150 'has a shape to cover a part of the supporting piece 112.

The resilient supporting portion 150 'may have a shape to cover a lower portion of the supporting piece 112 and may preferably cover a lower portion of the supporting piece 112 with a width not covering the slit 114. The elastic supporting portion 150 'may be formed so as to surround a lower part of the supporting piece 112 and be spaced apart from the supporting piece 112 or may be formed in a state of being closely attached to the lower side of the supporting piece 112 .

In the above-described embodiment, the elastic supporting part is in the form of a block, and the elastic supporting part is formed in a semicircular shape instead of the block shape, and may be inserted between the supporting part and the supporting part . That is, any form capable of providing a repulsive force in a direction opposite to the direction of deformation of the support piece is included in the scope of the present invention.

One embodiment of the present invention described above and shown in the drawings should not be construed as limiting the technical spirit of the present invention. The scope of the present invention is limited only by the matters described in the claims, and those skilled in the art can improve and modify the technical spirit of the present invention in various forms. Accordingly, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
