Abstract

<P>PROBLEM TO BE SOLVED: To aim at common use of a male/female terminal so as to reduce size. <P>SOLUTION: A tab of a connection terminal with a connection part formed by extending a pair of gutter-shaped tabs adhered back-to-back from a base part continuously formed at a wire connection part, is inserted into a gap of a pair of tabs of a counter part connection terminal having the same shaped tab, so as to aim at connection by crimping with each other with the use of a spring property of the tabs. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a male / female shared terminal that does not require separate use of a male terminal and a female terminal.

  The normal electrical connection terminal is composed of a male terminal and a female terminal. For this reason, when connecting an electric wire, it was necessary to attach a male terminal to one electric wire, and to attach a female terminal to the other electric wire, and the proper use of a male terminal and a female terminal was troublesome. In order to solve this problem, a male / female shared terminal is proposed in which a male terminal and a female terminal are formed side by side so that their central axes are parallel to each other.

  In this proposed male / female shared terminal, the tip surface of the male terminal part and the tip surface of the female terminal part are in the same position in the axial direction. Since there is no meaning unless male and female are shared, in order to fit the male terminal part and female terminal part of one terminal with the female terminal part and male terminal part of the other terminal, respectively, It is necessary to make it uneven so that the terminal portion is exposed and the female terminal portion is hidden. This complicates the shape of the connector housing, leading to increased costs and insufficient strength.

The thing described in the patent document shown below as a male-female common terminal which enabled simplification of the front end surface shape of a connector housing was proposed. This conventional example is a male-female common terminal in which a male terminal part and a female terminal part are integrally formed with their respective central axes parallel to each other. The male terminal part and the female terminal part are the male terminal part is the tip of the female terminal part. It is formed by shifting in the axial direction so as to protrude more. Then, such a male / female common terminal is connected to a connector housing having a flat front end surface or a slight unevenness on the front end surface, and only the male terminal portion protrudes from the front end surface of the connector housing. It is incorporated so as to be located in

  The male / female common terminal described in the patent document is a combination of the structure of the conventional male terminal and female terminal, and therefore, the size is large and the miniaturization is difficult.

  It is an object of the present invention to provide a male / female shared terminal that can be miniaturized.

  In order to achieve the above-mentioned object, the present invention provides a tab having the same shape as a tab of a connection terminal in which a pair of hook-like tabs are extended back to back from a base portion coupled to the connection portion to form a connection portion. Are inserted into a gap between a pair of tabs of a pair of connection terminals of the other party, and are brought into pressure contact with each other by utilizing the spring property of the tabs.

  The present invention provides a connection terminal tab having a tab having the same shape as the connection terminal tab formed by extending two pairs of hook-shaped tabs back to back from the base portion coupled to the wire connection portion. Since it is inserted into the gap between a pair of two tabs and brought into pressure contact with each other using the spring property of the tabs, the male and female terminals can be shared and the size can be reduced, and connection reliability can be achieved. Will also improve.

  Embodiments of the present invention will be described below with reference to the drawings.

  The connection terminal 1 shown in FIG. 1 has a box-shaped base part 3 coupled to a wire connection part 2 to which an unillustrated electric wire is connected, and two connecting terminals 1 from opposite corners of the rectangular opening of the base part 3. A pair of tabs 4 and 5 are formed to extend. The entire connection terminal 1 is formed of a conductive material, and the electric wire connecting portion 2 is constituted by a barrel portion 2A for fixing the covering portion of the electric wire and a barrel portion 2B for fixing the wire portion. The tabs 4 and 5 constitute a connecting portion, and these tabs 4 and 5 have a hook-like (or shovel or spatula-like) spring property in which a central portion along the longitudinal direction is recessed in a U shape. When the barrel portions 2A and 2B of the connection terminal 1 are the upper surface, they are extended and formed at a position inclined by 45 degrees from a perpendicular perpendicular to the upper surface (see FIG. 2).

  FIG. 3 shows a plan view of the connection terminal 1. In order to connect the connection terminals having the same structure as this, the other connection terminal is rotated by 180 degrees about the axis in the connection direction between the terminals, and the other tab 4 In FIG. 2, the other tabs 4 and 5 are arranged on the right side of the tab 4 and on the left side of the tab 5 so that 5 is located in the gap between the other tabs 4 and 5. At this time, the connection reliability is also improved by bringing the tabs 4 and 5 into pressure contact with each other due to the spring property of the tabs 4 and 5.

  FIGS. 4 and 5 show a variation in the extension positions (arrangements) of the tabs 4 ′ and 5 ′ of the connection terminal 1 ′ of the counterpart to be connected. In this connection terminal 1 ′, a case where the terminals 1 and 1 ′ are connected while the barrels 2 </ b> A ′ and 2 </ b> B ′ are kept on the upper surface in the same manner as one connection terminal 1 is shown. In this connection terminal 1 ′, the arrangement of the tabs 4 ′ and 5 ′ is different from that of the tabs 4 and 5 (see FIG. 5).

  Connection terminals 1 (or 1 ') having the same structure can be connected to each other, or two types of connection terminals 1 and 1' having different arrangements of tabs 4 and 5 (4 'and 5') can be connected. It is. In any connection, the tabs 4 and 5 and the tabs 4 ′ and 5 ′ can be partially (or all) inserted into the inside of the mating base part 3 ′ and the base part 3. By doing in this way, size reduction in a connected state can also be achieved.

Claims (2)

  Two pairs of hook-like tabs extending back to back from the base portion coupled to the wire connecting portion are connected to each other to form a pair of connecting terminal tabs having the same shape. A male / female common terminal that can be inserted into the gap between tabs and pressed against each other using the spring property of the tab.   The male / female common terminal according to claim 1, wherein at least a part of the tab is inserted into a box-shaped base portion of the other connection terminal.
