Description

Terminal and connector using same

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal and a connector using the same, and more particularly, to a terminal made to be firmly supported by a terminal itself in a housing and a connector using the terminal.

The terminal is made of a conductive metal material and is installed inside the housing forming the outer appearance and the skeleton of the connector, and is engaged with the terminal of the mating connector to perform electrical connection.

When the terminal is installed inside the housing and is engaged with the mating terminal of the mating connector, it is pushed by the mating terminal, and by this operation, the terminal tries to move in the direction of coming out of the housing. In order to prevent such an operation, a terminal or a housing is provided with a lance so that the terminal is supported by the housing so as not to be pushed by the mating terminal.

However, it is difficult to support the terminal only by the lance due to the problem of miniaturization of the terminal, and the terminal is prevented from being pushed by using the spacer, the front holder, the rear holder, and the like. If a spacer, a front holder, a rear holder or the like is used, the size of the housing becomes large and the number of parts increases.

As shown in the figures, the terminal 10 of the present embodiment is made of a conductive metal material. The terminal 10 is typically made with one metal plate. Of course, a plurality of terminals 10 are sequentially made from one metal plate.

The terminal 10 has a body portion 12 and the body portion 12 has a coupling portion 14 at its tip end. The engaging portion 14 is a portion that engages with the counterpart terminal. Since the present embodiment is a male terminal, the engaging portion 14 is inserted into the inside of the mating terminal. It will be readily apparent to those skilled in the art that the present invention can also be applied to a dark terminal, which is an opponent terminal of a male terminal.

A barrel portion 16 is provided at the rear end of the main body portion 12, that is, on the opposite side of the engaging portion 14. The barrel portion 16 is a portion to be coupled with the wire. In the drawing, the barrel portion 16 is shown in a schematic and omitted form rather than being shown precisely.

A lance hanger hole (18) is formed on an outer surface of one side of the main body (12). In the present invention, the main body portion 12 has a cylindrical shape with a hollow space formed therein. Therefore, the inside and the outside of the main body 12 communicate with each other through the lance hanger hole 18. The lance hanger 18 is provided with a lance 40 in the housing 32, which will be described below. A stabilizer (20) protrudes at one side of the lance hanger hole (18). The stirrer 20 guides the direction in which the terminal 10 is inserted into the terminal space 34.

An interlocking hook hole 22 is provided on the opposite side of the lance hook hole 18. The hooking piece 30 of the lance interlocking hook 24, which will be described later, protrudes to the outside through the interlocking hook hole 22. The interlocking hook hole 22 is formed to have a narrow width and a long length in this embodiment. The lance interlocking hook 24 protrudes from the main body 12 through the interlocking hook hole 22. Of course, the degree of protrusion of the lance interlocking hook 24 to the outside of the main body 12 is not large when the terminal 10 is not inserted into the housing 32 at normal times.

And a lance interlocking hook (24) extending from one side of the interlocking hook hole (22). The lance interlocking hook 24 serves to prevent the terminal 10 from being pushed by the counter terminal by being hooked on the back surface 44 of the housing 32. At the front end of the lance interlocking hook 24, a hooking piece 30 is provided. The hooking piece 30 is made to extend in the direction of the barrel portion 16 of the terminal 10 when the hooking piece 30 is hooked on the back surface 44 of the housing 32.

The lance interlocking hook 24 has a connecting piece 26 extending from the main body 12. The connecting piece 26 is located at a position corresponding to the interlocking hole 22. The connecting piece 26 extends obliquely into the main body 12. And an interlocking piece (28) extending from a distal end of the connecting piece (26). The interlocking piece 28 is interlocked with the hooking jaw 42 in the lance 40 of the housing 32. A portion of the linking piece 28 connected to the linking piece 28 is connected to the lance 40 when the terminal 10 is completely inserted into the housing 32. [ As shown in Fig. The interlocking piece 28 extends substantially in a direction transverse to the main body 12.

A hooking piece 30 is formed at the tip of the interlocking piece 28. The hooking piece 30 is a portion which is hooked on the backing wall 44 of the housing 32. It is preferable that the extending direction of the hook piece 30 is the longitudinal direction of the terminal 10 when the insertion of the terminal 10 is completed. This is to allow the hooking piece 30 to withstand the force in the direction in which the mating terminal is inserted.

The housing 32 forms an outer appearance and a skeleton of the connector. In the drawings, only a few important configurations are presented for convenience of the city. The housing 32 is made of an insulating synthetic resin. A terminal space (34) is formed through the inside of the housing (20). The terminal 10 is located in the terminal cylinder space 34. The terminal space 34 may extend through the housing 32 to form a plurality of terminal spaces.

Inside the terminal space 34 is a terminal outlet 36. The body portion 12 of the terminal 10 in the terminal space 34 protrudes through the terminal outlet 36. There is a jig hole 38 alongside the terminal outlet 36. Through the jig hole 38, a tool for separating the coupling between the lance 40 and the terminal 10, which will be described below, is inserted into the terminal space 34.

Inside the terminal space 34 is a lance 40. The lance 40 is formed in a cantilever shape, and has a hook 42 at its tip end. The hooking jaw 42 is hooked to one side of the lance hooking hole 18 of the terminal 10.

On the opposite side of the inner surface of the terminal space 34 where the lance 40 is located, the back surface 44 is formed. The back surface (44) is formed so as to see the terminal outlet (36) side of the terminal space (34). The hooking piece 30 of the terminal 10 is hooked on the back side 44 of the hook.

Hereinafter, the assembly and use of the terminal and the connector using the terminal according to the present invention will be described in detail.

The lance interlocking hook 24 of the terminal 10 is inserted into the terminal seating space 34 of the housing 32 and the interlocking piece 28 and the connecting piece 26 are inserted through the lance hooking hole 18, The connected part slightly protrudes. The hooking piece 30 is located inside the main body 12.

5, when the end of the interlocking piece 28 is inserted into the terminal seating space 34 of the housing 32 through the lance hanger hole 18, And is in close contact with the inner surface of the terminal seating space 34.

When the terminal 10 is continuously inserted in this state, the lance 40 is elastically deformed while the hooking jaws 42 at the tip of the lance 40 contact the outer surface of the main body 12. Such a state can be seen in FIG. At this time, the hook piece 30 of the lance interlocking hook 24 also moves in a state of being closely attached to the inner surface of the terminal seating space 34.

When the terminal 10 is continuously inserted in a state where the lance 40 is elastically deformed, the hooking jaw 42 at the tip of the lance 40 meets the lance hooking hole 18, The elastic deformation of the lance 40 is restored at the moment when the lance 40 is seated and hooked on the lance hook hole 18.

At the same time, one end of the interlocking piece (28) is pressed by the hooking jaw (42) of the lance (40). When the interlocking piece 28 is pushed by the hooking jaw 42, the hooking piece 30 is hooked on the backing wall 44, and the state shown in FIG. 4 is obtained. As can be seen, the hooking jaw 42 of the lance 40 is hooked on one side of the lance hanger hole 18 so that the terminal 10 is pushed by the mating terminal, 24 are hooked on the back surface 44 of the housing 32 so that the terminal 10 is also prevented from being pushed by the mating terminal.

Particularly, since the terminal 10 is prevented from being pushed by the lance 40 and the back 44 on both sides of the main body 12, the terminal 10 is stably supported as a whole, .

In order to separate the terminal 10 from the terminal seating space 34 of the housing 32, a jig is inserted through the jig hole 38 to hang the tip of the lance 40. By such an operation, the hooking jaws 42 are pulled out of the lance hooking hole 18.

When the latching hook 42 of the lance 40 is disengaged from the lance hooking hole 18, the lance interlocking hook 24 is restored to the elastically deformed state, The hooked state is released. In this state, when the terminal 10 is taken out of the terminal seating space 34, the terminal 10 is disconnected.

As described above, in the present invention, since the lance interlocking hook 22 is operated in conjunction with the lance 40, two configurations for supporting the terminal 10 on the housing 32 are interlocked with each other. Therefore, no additional parts are added, so that the assembling process is not increased, and further operation is not required even in the operation for pulling out the terminal 10 from the housing 32.
