Description

Terminals {TERMINAL}

The present invention relates to a terminal for realizing a stable connection structure through a mating terminal.

Japanese Patent Application Laid-Open No. 2000-150041 discloses a terminal having a box portion into which a mating terminal is to be inserted, an elastic bending portion disposed inside the box portion, and an opposite contact portion disposed on the opposite side of the elastic bending portion, as shown in Fig. . The indent portions 23 and 16a protruding toward each other are provided at positions opposite to each other on the elastic bending portion and the opposite contact portion. The mating terminal inserted into this terminal is brought into contact with the terminal at two points by the indent portions 23 and 16a.

Japanese Patent Application Laid-Open No. 2002-063961 discloses a protruding female terminal 100 having first contacts A10 and A20 protruding from a plate portion 80 (substrate) as shown in Fig. 12 . The mating terminal inserted into the protruding female terminal 100 comes into contact with the protruding female terminal 100 at the third point by the upper contacts of the first contacts A10 and A20 and the protruding female terminal 100. [ Since the protruding female terminal 100 has the first contacts A10 and A20, the size of the protruding female terminal 100 itself increases in the height direction.

When the tab portion of the mating terminal is inserted into the terminal, it is necessary to insert the tab portion by bending the elastic bending portion. On the other hand, at the insertion completion position, the bending restoring force of the elastic bending portion is used as the contact load. Therefore, it is difficult to insert with low insertion force in the terminal insertion process, and it is difficult to obtain a strong contact load at the insertion completion position. In addition, since the contact is formed in the two indent portions, there is a disadvantage that the contact state becomes unstable, the contact resistance becomes unstable, and the resistance to vibration is poor.

In addition, it is necessary to reduce the insertion force in the process of inserting a plurality of tabs (connector fitting) without increasing the height, and it is necessary to prepare a connector terminal with stable contact.

Accordingly, it is an object of the present invention to provide a terminal capable of inserting a mating terminal by a low insertion force in the terminal inserting process, and to obtain a strong contact load at the insertion completion position while suppressing the height of the terminal itself . In addition, the present invention also aims to provide a terminal having a stable contact state, stable contact resistance, and excellent resistance to vibration.

The present invention has been made in view of the above disadvantages. According to one embodiment of the present invention, there is provided a connector comprising a terminal as a terminal, a box portion into which a mating terminal is to be inserted, an elastic bending portion disposed inside the box portion, and an opposite contact portion disposed on the opposite side of the elastic bending portion, The tab portion of the mating terminal inserted through the elastic bending portion is inserted by the bending deformation of the elastic bending portion and the tab portion is brought into contact with the opposite contact portion by using the elastic restoring force of the elastic bending portion as the contact load. The elastic bending portion includes an indent portion protruding toward the side of the opposite contact portion. The opposite contact portion is provided on the elastic bending portion side thereof, upstream of the indent portion position with respect to the insertion direction of the tab portion of the mating terminal, And the space between the front projecting portion and the rear projecting portion is made to have a size allowing the insertion of the tab portion of the mating terminal. The opposite contact portion includes a concave surface formed on the elastic bending portion side surface of the opposite contact portion and between the front projection portion and the rear projection portion.

In the terminal according to one embodiment of the present invention, the concave surface connected to the rear protrusion may be formed as a curved surface.

In the terminal according to one embodiment of the present invention, the concave surface connected to the rear protrusion may be formed as a tapered surface.

[Description of First Embodiment]

A first embodiment of the present invention will be described with reference to Figs. 1 to 8B. As shown in Fig. 1, a terminal for ensuring stable contact includes a box portion 1 and a rubber stopper 1A for ensuring the sealing characteristics of the electric wire. In addition, as shown in Fig. 2, the terminal is housed in the housing 1B to ensure insulation from the outside, and is formed to allow insertion of the mating terminal.

3, the terminal according to the present embodiment includes a box portion 1 to which a mating terminal is to be inserted, an elastic bending portion 2 disposed inside the box portion 1, an elastic bending portion 2 disposed on the opposite side of the elastic bending portion 2, And an opposing contact portion 3 arranged thereon. The tab portion 11 of the mating terminal is inserted between the elastic bending portion 2 and the facing portion 3 and the elastic bending portion 2 is bent and deformed. In this case, by using the bending restoring force of the elastic bending portion 2 as a contact load, stable contact between the tab portion 11 of the mating terminal and the terminal is ensured through the elastic bending portion 2 and the opposing contact portion 3.

The elastic bending portion (2) includes an indent portion (4) protruding toward the side of the contact portion (3). The opposite contact portion 3 is provided on the side of the elastic bending portion 2 at the position upstream of the position of the indent portion 4 and the position downstream of the position of the indent portion 4 with respect to the inserting direction of the tab portion 11 of the mating terminal And includes a front projection 5 and a rear projection 6 provided. The space between the front projecting portion 5 and the rear projecting portion 6 has a length d that is a length allowing the tab portion 11 of the mating terminal to enter. The opposing abutment portion 3 includes a concave surface 7 formed on the side surface of the elastic bending portion 2 thereof and between the front projection portion 5 and the rear projection portion 6. The front projections 5 and the rear projections 6 located on the front side and the rear side of the concave surface 7 serve as a contact portion to be brought into contact with the tab portion 11. [

Here, "upstream of the position of the indent portion 4" means a side closer to the insertion port of the box portion 1 into which the tab portion 11 is to be inserted than the position of the indent portion 4. That is, this means the side located on the front side of the position of the indent portion 4 along the inserting direction of the tab portion 11 of the mating terminal.

In addition, the term "downstream of the position of the indent portion 4" means a side farther from the insertion port of the box portion 1 into which the tab portion 11 is to be inserted than the position of the indent portion 4. That is, this means a side located behind the position of the indent portion 4 along the inserting direction of the tab portion 11 of the mating terminal.

Next, as a comparative example of the first embodiment, reference is made to Fig. 4 showing a state in which insertion of the mating terminal is completed. Unlike the first embodiment of the present invention, the opposite contact portion 13 is formed flat.

In contrast to the comparative example of Fig. 4, in the first embodiment shown in Figs. 5 and 6, the opposing abutting portion 3 is not formed flat but formed in a concave curved shape.

In the first embodiment, the position corresponding to the concave surface 7 connected to the rear projection 6 is composed of a curved surface 7a. That is, the concave surface 7 has a concave curved shape, has an R shape in the vicinity of the contact portion, and is formed continuously in one curved line. These curved surfaces are formed by embossing. This makes it possible to smoothly insert the tab portion 11 and insert the tab portion 11 so as not to be caught on the edge, so that peeling of the plating can be prevented, and therefore, reliability of energization can be ensured.

7A and 7B, the operation in which the tab portion 11 of the mating terminal is inserted into the terminal along the curved surface 7a will be described. The leading end side of the tab portion 11 enters the space in the concave surface 7 even when the pressing force is applied to the elastic bending portion 2 when the male and female connectors are fitted to each other. Therefore, an advantageous effect that the fitting force is reduced in the insertion process is obtained.

Reference is now made to Figs. 8A and 8B showing a comparative example for the first embodiment. Unlike the comparative example shown in Figs. 7A and 7B, the pressing force applied when the male and female connectors are fitted to each other is still applied to the elastic bending portion 2 during the insertion of the tab portion 11. However, since the surface of the opposed contact portion 13 is flat, the fitting force is not changed during the insertion process. In this comparative example, since the fitting force does not change during the inserting process, it is difficult to smoothly insert the tab portion 11 as compared with the terminal according to the present embodiment.

As described above, in the terminal according to the first embodiment, the concave surface 7 is formed in the side surface of the elastic bending portion 2 of the opposed contact portion 3 and between the front projection 5 and the rear projection 6. Therefore, even if a pressing force is applied to the elastic bending portion 2 when the male and female connectors are fitted to each other, the leading end side of the tab portion 11 enters the space in the concave surface 7, and the fitting force is reduced in the insertion process. Therefore, the terminal according to the present invention has an advantageous effect that it is possible to facilitate the insertion of the tab portion 11. [

[Description of the Second Embodiment]

Reference is now made to Figures 9 and 10. The concave surface 7 connected to the rear projection 6a is formed by a tapered surface 7b. The tapered surface 7b is formed by embossing.

The terminal according to the second embodiment has the same advantageous effect as the terminal according to the first embodiment. That is, the tapered surface 7b constituting the concave surface 7 is formed on the side of the elastic bending portion 2 of the contact portion 3 and between the front projection 5a and the rear projection 6a. Therefore, even if a pressing force is applied to the elastic bending portion 2 when the male and female connectors are fitted to each other, the leading end side of the tab portion 11 enters the space in the concave surface 7, and therefore, the fitting force is reduced in the insertion process. Therefore, the terminal according to the second embodiment has an advantageous effect that it is possible to facilitate the insertion of the tab portion 11.

In addition, in the terminal according to the second embodiment, in the terminal inserting process, when the tip of the tab portion 11 of the mating terminal is to be inserted while sliding on the concave surface, the tip of the tab portion 11 is inserted into the concave surface 7, So as to slide smoothly over the rear protruding portion 6 without colliding with the rear protruding portion 6a, and inserted into the insertion completion position. As a result, the tab portion 11 can be smoothly inserted.

While embodiments of the invention have been described above, it is to be understood that these embodiments are merely illustrative and are not intended to limit the scope of the present invention. The technical scope of the present invention is not limited to the specific technical contents disclosed in these embodiments, and includes various modifications, alterations, and alternative techniques that can be easily understood from the description.

This patent application claims priority based on Japanese Patent Application No. 2014-082544, filed April 14, 2014, the contents of which are incorporated herein by reference.

According to the embodiment of the present invention, in the process of inserting the tab portion of the mating terminal into the box portion, insertion into the space on the concave surface side of the tip end of the tab portion can be performed and the bending deformation of the elastic bending portion is minimized And the terminal comes into contact with the tab portion at three points of the indent portion, the front protruding portion, and the rear protruding portion at the insertion completion position. From the above description, insertion of the mating terminal in the terminal inserting process becomes possible by a low insertion force, and it becomes possible to obtain a strong contact load at the insertion completion position. Further, the advantageous effect is obtained that the contact state is stabilized, the contact resistance is stabilized, and the resistance to vibration is improved.
