Abstract
Description
The present invention relates to a fork terminal, and more particularly, to a fork terminal assembly having a terminal shield for protecting a fork terminal and a junction box including the fork terminal assembly.
The junction box located in the vehicle engine room mainly performs functions such as power supply and distribution and wire protection. In addition, the junction box stores and protects electronic devices (fuses, relays, etc.) , And maintenance of operating efficiency through rapid heat dissipation.
These junction boxes can be classified into Conventional, Bus-Bar, Cylindrical, PCB (Printed CircuitBoard) according to their types. Among them, the PCB type junction box can be classified into a flat insertion type And vertical insertion type.
Due to the addition and refinement of various convenience features of the vehicle, it is required to accommodate more electronic devices inside the junction box, so that a more compact and integrated junction box is required to be developed. Therefore, the PCB type junction box is required to be flat It is being developed as a vertical insertion type rather than an insertion type.
1, a conventional vertically-insertable PCB type junction box includes a PCB 1, which is a kind of bottom-most circuit board, and a terminal assembly that covers the top of the PCB 1, And includes a fork terminal (3) and a housing (5) coupled to the top of the fork terminal (3).
An electronic component such as a
The
Such conventional techniques have the following problems.
There is a problem that the fork terminal 3 is easily deformed by an external force in the moving process for the next assembly or the assembling process of other parts in a state where the fork terminal 3 is installed in the junction box. Particularly, before the
The fork terminal 3 is formed in a relatively small size so that the allowable current is very limited. In the case where a current equal to or higher than the allowable reference is applied, the fork terminal 3 is overheated and dissolves parts of the synthetic resin material around the
It is an object of the present invention to prevent deformation of a fork terminal due to an external force.
Another object of the present invention is to increase the allowable current of the fork terminal assembly by using a terminal shield surrounding the fork terminal.
According to an aspect of the present invention for achieving the above-mentioned object, the present invention provides a connector comprising: a fork terminal having a pair of terminal arms coupled with terminals of a counterpart and an inserting portion inserted into the through hole of the PCB substrate; And a terminal shield coupled to the fork terminal to surround the side surfaces of the pair of terminal arms in a state that the terminal arms are exposed upward.
Wherein the terminal shield is formed to be open upward and the center of the terminal shield is formed with a relative insertion portion being opened along a direction in which the fork terminal is coupled with a pair of arm shield portions Respectively.
The outer surface of the fork terminal and the inner surface of the terminal shield facing the outer surface of the fork terminal are provided with moving slits and hooking protrusions corresponding to each other, and the moving slit extends in the elastic deformation direction of the arm shield portion of the terminal shield.
The outer surfaces of the fork terminals and the inner surfaces of the terminal shields facing the outer surfaces of the fork terminals are provided with coupling grooves and coupling protrusions corresponding to each other to prevent separation of the fork terminals and the terminal shield.
The terminal shield is made of aluminum or an aluminum alloy.
A deformed slit is formed between the pair of female shield portions of the terminal shield so as to extend in the direction of joining the terminal shield and the fork terminal.
And an extension portion is formed at one end of the arm shield portion so as to extend in a direction corresponding to a direction in which the pair of terminal arms are apart from each other.
According to another aspect of the present invention, there is provided a junction box comprising: a junction box body; a PCB substrate mounted on the junction box body; a fork terminal having a pair of terminal arms, And a terminal shield which is coupled to the fork terminal so as to surround the pair of terminal arms while exposing the inserting portion downwardly, and a terminal shield which is fixed to the junction box body so as to expose the fork terminal, .
The housing includes an actuator protruding thereon, and an arm shield portion of the terminal shield is provided with an inclined portion corresponding to the actuator. When the housing is coupled to the junction box body, the actuator contacts the arm shield portion of the terminal shield And elastically deforms in a direction away from the terminal arm.
A pair of arm shield portions corresponding to the terminal arms are provided on both sides of the relative insertion portion, and the pair of arm shield portions are provided at both sides of the arm shield portion, A deformed slit is formed between the arm shield portions so as to extend in the direction of joining the terminal shield and the fork terminal.
In the fork terminal assembly according to the present invention as described above and the junction box having the same, the following effects can be expected.
In the present invention, since the fork terminal is held in a state surrounded by the terminal shield, it is possible to prevent the fork terminal from being deformed or damaged by an external force, and thus the durability of the fork terminal assembly and the convenience of assembling the junction box can be improved have.
In the present invention, since the terminal shield is made of a metal material such as aluminum and is coupled to the fork terminal so as to perform the function of current transfer, the allowable current of the fork terminal assembly is increased. As a result, Durability and compatibility are also improved.
In addition, in the present invention, since the fork terminal is wrapped by the terminal shield, the fork terminal is prevented from being excessively deformed outwardly so that the terminal inserting force of the fork terminal is maintained at a certain level or more, Level, and as a result, the operation reliability of the junction box is improved.
According to the present invention, in the course of coupling the housing to the fork terminal assembly, the actuator shield of the housing is opened naturally to the outside, thereby ensuring a sufficient space for elastically deforming the fork terminal, So that the assembling property of the junction box can be improved.
