Description

Tab terminal {Tab terminal}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tap terminal, and more particularly to a tap terminal having a reinforced rigidity at a connection portion between a connection portion electrically connected to a mating terminal and a main body portion.

The terminal is made of a conductive material to perform an electrical connection, and the tap terminal and the receptacle terminal are coupled to each other to perform an electrical connection. Wherein the tab terminal is connected to the connecting portion of the distal end portion by being inserted into the coupling portion of the receptacle terminal.

For this purpose, the connections of the tap terminals are made relatively small or high in height compared to the other parts of the tap terminals. In recent years, miniaturization of various electronic apparatuses has been demanded, and a connector in which a tap terminal is used is also required to be miniaturized. In order to miniaturize the connector, the tap terminal also has to be miniaturized. However, there is a problem that the small coupling portion becomes smaller and its rigidity is weakened.

Particularly, in the conventional tap terminal as disclosed in the prior art document, stress is concentrated only at the portion where the intermediate portion and the terminal connecting portion are connected, and plastic deformation mainly occurs at the portion where the intermediate portion and the terminal connecting portion are connected. This is because the cross-sectional area changes discontinuously at the portion where the intermediate portion and the terminal connecting portion are connected. Particularly, since the shape and size of the quadrangle are rapidly changed in the connecting portion between the intermediate portion and the terminal connecting portion in the prior art, the stress is concentrated on the portion, But it is plastic-deformed and severely severed.

According to the drawings, the terminal of this embodiment is made of a conductive metal material. The terminal of the present embodiment is formed by folding a metal plate as shown in Fig. 6, and includes a body portion 10, a connection portion 20, and a barrel portion 30. The main body 10 is a central part of the terminal, and the connection part 20 is integrally connected to the tip end, and the barrel part 30 is integrally connected to the rear end. The connection portion 20 is a portion electrically and electrically connected to a receptacle terminal which is a partner terminal. The barrel portion 30 is a portion to which a wire is connected.

The body portion 10 has a square pillar shape and extends in the longitudinal direction and has a rectangular cross section. The main body portion 10 includes a main body bottom plate 11 and a first main body side plate 12 and a second main body side plate 12 which are connected to both sides of the bottom plate 11 in the width direction, A first main body floating plate 13 extending from the first main body side plate 12 and facing the main body bottom plate 11 and a second main body floating plate 13 extending from the second main body side plate 12 ' And a second body floating plate 13 'facing the sub floor plate 11.

A through hole 14 is formed at a longitudinal middle portion of the main body bottom plate 11 of the main body 10 so that the inside and the outside of the main body 10 communicate with each other. A lance hanger protrusion 15 is formed at one side edge of the through-hole 14. The lance hook protrusion 15 is hooked by a lance in a housing (not shown). Reference numeral 16 denotes a stabilizer.

The first and second main body side plates 12 and 12 'and the first and second main flotation plates 13 and 13' are narrowed at the leading end portion connected to the connecting portion 20, The cross sectional area of the front end portion of the main body portion 10 gradually becomes narrow. This portion will be referred to as a connecting portion 17 for the sake of convenience.

The connecting portion (20) extends integrally from the connecting portion (17). The portion where the connection portion (17) and the connection portion (20) are connected to each other at a sudden change in dimension is the upper and lower surface side transition portion (18) and the side side transition portion (19). The upper and lower surface transition portions 18 are formed by a portion where the bottom plate 11 of the main body portion of the main body portion 10 and the connecting portion bottom plate 21 of the connecting portion 20 are connected with each other at a predetermined angle, The first and second main body floating plates 13 and 13 'of the first and second connecting portions 20 and 20 are connected to the first and second connecting portion upper plates 23 and 23' of the connecting portion 20 at a predetermined angle. Since the bottom plate 11 of the main body portion and the first and second main flotation plates 13 and 13 'are positioned opposite to each other, the top and bottom transition portions 18 are also disposed on the main body portion 10 or the connecting portion 20 They are in positions facing each other in a rectangular cross section.

The side surface portion 19 of the main body portion 10 is connected to the first main body side panel 12 of the main body portion 10 and the first connecting portion side panel 22 of the connecting portion 20, The second main body side plate 12 of the main body portion 10 and the second connecting portion side plate 22 'of the connecting portion 20 are connected to each other at a predetermined angle.

Here, the positions of the upper and lower surface transition portions 18 and the side surface transition portions 19 are different from each other. That is, in this embodiment, the upper and lower surface transition portions 18 are farther from the tip end of the connection portion 20 than the side surface transition portion 19. When the stress due to the external force is generated due to the different positions of the upper and lower surface side transition portions 18 and the side side transition portions 19, a portion where stress is concentrated is applied to the upper and lower surfaces of the main body portion 10 and the connection portion 20, And that they are different from each other.

The concrete structure of the connection portion 20 is as follows. The bottom plate 21, the first and second connecting part side plates 22 and 22 ', and the first and second connecting part upper plates 23 and 23' constituting the connecting part 20 are connected to the main body part 10 The first and second main body floating plates 13 and 13 'are extended from the main body bottom plate 11, the first and second main body side plates 12 and 12' and the first and second main body floating plates 13 and 13 ' 20 are smaller in size than the main body 10. Particularly, when the cross-sectional area of the main body 10 is compared with that of the connecting portion 20, the size of the connecting portion 20 is much smaller than that of the main body 10.

In the connecting portion 20, the second connecting portion upper plate 23 'exists together with the first connecting portion upper plate 23 only in a partial section, and only the first connecting portion upper plate 23 exists in the remaining portion. This is because the dimensions of the connecting portion 20 are relatively small so that the first main floating plate 23 and the second main floating plate 23 ' To form a top plate.

The first distal end slanting piece 25 and the second leading end slanting piece 26 are provided at the front end of the connecting portion 20 so as to face each other and are inclined so as to be closer to each other toward the front end. This is to facilitate coupling with the receptacle terminal which is an opponent terminal. The first end inclined piece 25 extends from the first connecting part upper plate 23 and the second leading end inclined piece 26 extends from the connecting part bottom plate 21.

The barrel 30 is composed of an insulation barrel 32 and a wire barrel 34. The insulation barrel 32 surrounds the outer surface of the wire, and the wire barrel 34 surrounds the core wire inside the wire with the insulation removed.

On the other hand, although not shown in the drawing, the connecting portion 20 may be formed of a relatively thick metal plate without folding the metal plate. Even in such a case, the portion to which the main body portion 10 and the connection portion 20 are connected is disposed at a position where the mutually adjacent portions 18 and 19 are located at mutually different positions on the outer surface adjacent to the main body portion 10 and the connection portion 20, So that stress concentration can be avoided. This is also the case when the connection portion 20 is welded to the main body portion 10 or when the main body portion 10 is integrated with the connection portion 20 to form a tab terminal.

Hereinafter, a tap terminal according to the present invention will be described in detail.

In the embodiment shown in the drawing, the metal plate is cut in a state as shown in FIG. 6, and the metal plate is folded to make the tab terminals shown in FIG. 1 and FIG. 6, the first main body floating plate 13 of the main body part 10 and the first connection part upper plate 23, the second main body floating plate 13 ', and the connection part 20 of the connection part 20, The first main body side plate 12 is connected to the first connecting portion side plate 22 of the connecting portion 20 and the second main body side panel 12 'Are connected to the second connecting portion side plate 22' of the connecting portion 20. The bottom plate 11 of the main body 10 and the bottom plate 21 of the connecting portion 20 are connected to each other.

The tapping terminal shown in FIGS. 1 and 2 is made by folding the base material having the above-described structure while passing through the progressive die. In the process of forming the tab terminal, the upper and lower surface side transition portions 18 and the side side transition portions 19 may not be clearly bounded to the periphery. That is, as shown in the drawings, the top and bottom side portions 18 and the side side portions 19 are not formed in a clear line, but can be formed into a round shape.

The upper and lower surface transition portions 18 and the side surface transition portions 19 which are the boundary between the main body portion 10 and the connection portion 20 are located at different positions from each other and the applied stress is dispersed. For example, when the upper and lower surface transition portions 18 and the side surface transition portions 19 are located at the same position, the stress due to the external force is concentrated at the same position with respect to the four surfaces of the connection portion 20, It is possible to greatly reduce stress concentration.

By designing the boundary between the connecting portion 20 and the main body 10 as described above, the stress concentration is reduced and the rigidity of the connecting portion 20 is relatively increased, so that the durability of the tap terminal is relatively improved.

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The scope of protection of the present invention should be construed according to the following claims, and all technical ideas within the scope of equivalents should be construed as falling within the scope of the present invention.
