Abstract

(57) [Summary] [Purpose] When inserting a male terminal consisting of a tab into the female terminal housed in the connector, if the tab is slightly deformed, the female terminal can be displaced along the tab. As a result, the female terminal can be prevented from being deformed in advance, while the tab cannot be inserted when the deformation amount of the tab is large. [Structure] The terminal 14 is formed by the inclined surfaces 15d and 15e formed on the inner surface of the cavity 15a of the second housing 15.
Restricts the swinging on the front side and allows the swinging on the rear side. Even if the tab 12 is deformed within a predetermined angle θ1, the rear side of the terminal 14 naturally swings so as to match the deformation angle of the tab 12 during insertion. The diameter of the insertion port 15f of the second housing 15 is specified so that the tab 12 has a predetermined angle θ1.
When it is deformed more than once, it cannot be inserted from the insertion port 15f.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connector for connecting a terminal, and more particularly to a connector suitable for inserting a male terminal, which is a charging tab for an automobile battery, into a female terminal crimped to a wire harness.

[0002]

[Prior Art]

 Conventionally, as such a connector, a male terminal (tongue tab) protruding from the first housing of an automobile battery is crimped with a wire harness housed in a cavity (container) of the second housing. A female terminal is provided which is adapted to be inserted through the insertion port of the second housing. In the connector described above, the cavity of the second housing is normally positioned and accommodated so that the female terminal does not rattle.

[0003]

[Problems to be solved by the device]

 However, there is no problem when the angle of the tab of the first housing is not deformed, but when the angle of the tab is deformed, the insertion into the female terminal cannot be performed smoothly, and it is forcibly inserted. Then, there is a problem that the female terminal itself is also deformed, resulting in poor contact.

Therefore, an object of the present invention is to prevent deformation of the terminal accommodated in the accommodating chamber of the connector by itself and to prevent insertion of the tab when deformation of the tab is large. The purpose is to provide a connector that can detect deformation.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a male terminal, which is a tab-like tab protruding from a first housing, to a female terminal crimped with a wire harness housed in a cavity of a second housing. In a connector which is adapted to be inserted through an insertion port of a housing, an inclined surface is formed on an inner surface of a cavity of the second housing so as to restrict swinging of the front side of the terminal and allow swinging of the rear side. It provides a connector that is characterized by the fact that

Further, it is preferable that the insertion port of the second housing is formed to have a diameter that allows the tab to be inserted within a predetermined deformation angle.

[0007]

[Action]

 According to the connector of the present invention, the inclined surface formed on the inner surface of the cavity of the second housing restricts the rocking of the front side of the terminal housed in the cavity and allows the rocking of the rear side. As a result, even if the tab is deformed within a predetermined angle, the rear side of the terminal naturally swings so as to match the deformation angle of the tab during insertion, so that the terminal can be inserted smoothly. Therefore, even if the tab is deformed, the terminal is not deformed, so that contact failure does not occur and the quality is stable.

Further, by specifying the diameter of the insertion port of the second housing, when the tab is deformed by a predetermined angle or more, the tab cannot be inserted from the insertion port. As a result, it is possible to prevent the tab from being forcedly inserted that is deformed at an angle that cannot be absorbed by the swing of the terminal, and detect the deformation of the tab.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. As shown in FIG. 3, the first housing 11 of the automobile battery 10 is provided with tongue-shaped charging tabs 12 and 12 that project laterally. The tabs 12 constituting these male terminals normally project horizontally as shown by the chain double-dashed lines in FIGS. 1 and 2, but due to manufacturing errors, external forces during storage, etc., the tabs shown in FIG. It may be deformed at a small angle θ1 (for example, 3 degrees) as shown by the solid line, or at a large angle θ2 (for example, 8 degrees) as shown by the solid line in FIG.

On the other hand, female terminals 14 are attached by crimping to the tips of the electric wires 13 a of the wire harness 13. As shown in FIGS. 1 and 2, each female terminal 14 includes a barrel portion 14a that is crimped to the electric wire 13a and a spring tongue piece that extends from the bottom side of the barrel portion 14a to the tip side and is folded back in a U shape. The spring tongue portion 14b and the pressing piece portion 14c extending from the side surface portion to the tip end side of the barrel portion 14a to form a space for inserting the tab 12 between the spring tongue piece portion 14b. The piece portion 14b and the holding piece portion 14c form an electric contact portion.

Cavities (accommodation portions) 15a, 15a for accommodating and accommodating the female terminals 14 from the rear are provided in the second housing 15 accommodating the female terminals 14 crimped to the electric wires 13a of the wire harness 13. Are formed.

As shown in FIGS. 1 and 2, each of the cavities 15a is not an inner surface shape for accommodating and accommodating the female terminal 14 so that the female terminal 14 does not rattle, as in the conventional cavity. It is formed to have an inner surface shape having a height H2 higher than the height H1. Therefore, if this is left as it is, the female terminal 14 will rattle upward and downward.

Therefore, the inclined surfaces 15d and 15e of the ridge, which are gradually inclined from the front to the rear, are integrally formed at the widthwise intermediate portions of the upper surface 15b and the lower surface 15c of the inner surface of the cavity 15a. ing. By providing the inclined surfaces 15d and 15e, the front side of the surface terminal 14 is regulated so as not to rattle in the vertical direction between the front portions of the inclined surfaces 15d and 15e projecting in the directions in which they approach each other. On the other hand, the rear side of the female terminal 14 is allowed to swing up and down within a range where it abuts on the inclined surfaces 15d and 15e.

An insertion port 15f for inserting the tab 12 into the terminal 14 in the cavity 15a is provided in the front portion of the second housing 15, and the insertion port 15f is shown by a solid line in FIG. Only the tab 12 within the shown small deformation angle θ1 is formed to have a diameter capable of being inserted.

With the above configuration, when the tab 12 of the first housing 11 is horizontal, the female terminal 14 in the cavity 15a is inserted into the tab 12 through the insertion port 15f of the second housing 15. Can be inserted smoothly.

When the tab 12 is deformed at a large angle θ2 as shown by the solid line in FIG. 2, the tab 12 comes into contact with the outer surface 15g of the insertion port 15f of the second housing 15, so that the difference I can't get into it. As a result, it is possible to prevent the tab 12 from being unreasonably inserted and to detect the deformation of the tab 12.

When the tab 12 is deformed at a small angle θ1 such as 3 ° or less as shown by the solid line in FIG. 1, the tab 12 should be inserted into the insertion port 15f of the second housing 15. You can Then, when the tab 12 is inserted into the female terminal 14, the rear side of the female terminal 14 is naturally swung so as to match the deformation angle θ1 of the tab 12 by the inclined surfaces 15d and 15e during the insertion. Therefore, the female terminal 14 can be smoothly inserted. As a result, the terminal 14 is not deformed and contact failure does not occur, so that the quality becomes stable.

[0018]

[Effect of the device]

 As is clear from the above description, the connector of the present invention has the inclined surface formed on the inner surface of the cavity of the second housing to restrict the swing of the front side of the terminal and allow the swing of the rear side. It was done like this. Therefore, even if the tab is deformed within the specified angle, the rear side of the terminal will swing naturally to match the deformation angle of the tab during insertion, so that the terminal can be inserted smoothly and the terminal will not deform. Therefore, contact failure does not occur and the quality becomes stable.

Further, by specifying the diameter of the insertion port of the second housing, when the tab is deformed by a predetermined angle or more, it cannot be inserted from the insertion port, so it is absorbed by the swing of the terminal. It is possible to prevent the tab that is deformed at an unbreakable angle from being inserted unreasonably. In addition, when the tab cannot be inserted, the deformation of the tab can be detected.
