Referring to Figures 1 to 3, the joint connector 100 according to an embodiment of the present invention includes a wire terminal 110 coupled to an end of a wire 111 and a connector housing in which a plurality of wire terminals 110 are coupled ( 120), a holder 130 that is inserted into the connector housing 120 and fixes the wire terminal 110, and a connection terminal 140 that protrudes downward on the holder 130 and electrically connects the wire terminal 110. Includes.

The connector housing 120 can be either a male connector or a female connector, and in this embodiment, the one applied to the male connector will be described as an example.

As shown in FIG. 1, a plurality of wires 111 are coupled to one side of the connector housing 120 of the male connector. The wire 111 is coupled with the wire terminal 110 coupled to the end, and when the wire terminal 110 is inserted into the connector housing 120, as shown in FIG. 2, the holder 130 As the is fastened, the connector housing 120 and the wire terminal 110 are coupled.

Here, the holder 130 is coupled to the connector housing 120 and functions to prevent the wire terminals 110 from being removed from the connector housing 120, and at the same time connects the wire terminals 110 in a set pattern to the existing It carries the function of joint busbar.

The holder 130 is provided with a first interference member 131 protruding from the bottom so as to interfere with each wire terminal 110 coupled to the connector housing 120.

The first interference member 131 is located between the wire 111 and the wire terminal 110, so that interference occurs in the direction in which the wire terminal 110 is removed, and the interference is released when the holder 130 is removed. .

In addition, second interference members 132 are provided on both sides of the holder 130, which are coupled to the connector housing 120 and interfere with each other between the holder 130 and the connector housing 120.

The second interference member 132 provides a function of preventing the holder 130 from being removed from the connector housing 120, and has a protrusion protruding from one of the holder 130 and the connector housing 120 and the other. It may be provided in a structure where a groove is formed in one. In this embodiment, the second interference member 132 protrudes from both sides of the holder as an example.

FIG. 4 is a perspective view showing the connection terminal of the holder shown in FIG. 3, FIG. 5 is a combined perspective view showing the connection terminal shown in FIG. 4 coupled to a wire terminal, and FIG. 6 is a connection terminal shown in FIG. 5 and the connection terminal shown in FIG. This is a cross-sectional view showing the connection state of the wire terminal.

4 to 6, the connection terminal 140 includes a body 141 that protrudes from the bottom of the holder 130 and is inserted into the coupling hole 112 formed on the wire terminal 110, and the body 141 ) It includes a contact member 145 that protrudes further outward from the top and contacts the inner peripheral surface of the coupling hole 112 to become a contact point.

In one embodiment, the body 141 has a square cross-section, and the coupling hole 112 is also formed on the wire terminal 110 to have a square cross-section.

A through hole 142 is formed on each side of the body 141, and the contact member 145 is disposed in each through hole 142 from the inside to the outside. Therefore, when the connection terminal 140 is inserted into the coupling hole 112, the contact member 145 and the wire terminal 110 come into direct contact and are electrically connected.

At this time, although not shown in the drawing, the coupling hole 112 is formed by partially bending the upper surface or side surface of the wire terminal 110, and the bent upper surface or side surface contacts the contact member 145 inside the coupling hole 112. It may have a function of elastically pressurizing while doing so.

In addition, since each of the four sides of the contact member 145 is in contact with the inner surface of the coupling hole 112, it is possible to prevent instantaneous contact failure even if an external force such as strong vibration is transmitted to the connector housing 120 from any direction. You can. That is, since each side of the contact member 145 on the inner peripheral surface of the coupling hole 112 is in contact (multiple contact points), the contact member 145 on at least one side serves as a contact point in response to impact from all directions. This can significantly reduce the occurrence of contact defects compared to the case where the contact point was maintained in one direction or up and down.

And each connection terminal 140 is connected in a set pattern inside the holder 130. In this case, the connection terminals 140 can be selectively plated to form a circuit for electrical connection.

First, the connection terminal 250 includes a body 251 protruding from the bottom of the holder 130 and an elastic member 255 flexibly disposed on the body 251.

Here, the body 251 has a circular cross-section, and the elastic member 255 has a structure that bends or moves inward when pressed on the body 251.

As shown in Figure 8, when the connection terminal 250 is coupled to the wire terminal 110, contact is made between the body 251 and the coupling hole 112 of the wire terminal 110 as shown in Figure 9. At this time, The elastic member 255 is deformed on the body 251 due to a predetermined pressing force due to contact. Here, the deformation may be an external deformation due to the elastic restoring force of the elastic member 255, or the elastic member 255 may slide into the body 251 through a separate elastic part (not shown) on the body 251. It can also be a moving transformation.

As shown in FIG. 10 , the elastic member 255 includes a third interference member 256 that protrudes outward to interfere with the coupling groove 113 formed on the inner peripheral surface of the coupling hole 112.

The third interference member 256 can increase the coupling force between the connection terminal 250 and the wire terminal 110 and prevent contact failure from occurring due to external forces such as vibration.

As such, according to the joint connector 100 according to the present invention, the assembly process can be reduced because the wires are electrically connected through the connection terminal provided in the holder, and the connection terminal can function as a joint bus bar. Therefore, costs can be reduced, the number of contact points between the connection terminal and the wire terminal is increased, and the effect of preventing contact defects is expected because the contact is elastic.
