Abstract

The utility model discloses a terminal, comprising a fixed part, a body part, a connection part, an elasticity part and a contact part. The body part extends for one side of the fixed part; the top end of the body part extends upward to be provided with the connection part; the tail end of the connection part reversely extends upward to be provided with the elasticity part; the contact part is arranged on the tail end of the elasticity part for compressing and contacting abutting electronic components. Compared with prior art, the terminal of the utility model has simple structure and easy manufacture, and the elastic arm of the terminal is longer, which is easy to maintain favorable elasticity, so as to guarantee having better electrical connection with the abutting electronic components.

Description

A kind of terminal

[technical field]

The utility model relates to a kind of terminal, is meant that especially a kind of energy compresses the terminal that contacts mutually with the butt joint electronic building brick.

[background technology]

The connected mode of electric connector and peripheral hardware electronic building brick is varied, and it is the electric connector that adopts compression to contact that a kind of and external electronic building brick is wherein just arranged, and electric connector to contact with the compression of external electronic building brick be to realize by terminal.Under prior art, as shown in Figure 1 and Figure 2, this terminal comprises a fixed part 1, is extended upward the strip linking arm 2 that obtains by fixed part 1; Then bend 180 main bodys 3 that obtain of degree by fixed part 1 downward extension again, main body 3 30 degree that bend inwards obtain elastic arm 4, upwards are the portion of pressing 5 to terminal by elastic arm 4; Extend the not crooked welding ends 6 that obtains downwards by fixed part 1 again.

During installation, earlier terminal is fixed in the insulating body 7, it is fixed in by its fixed part 1 in the holding tank 71 of insulating body 7, and is then that welding ends 6 is fixing with circuit board (not drawing among the figure) welding.During use, will dock electronic building brick (not drawing among the figure) and press from top to bottom, and reach with the portion that presses 5 of contact arm 4 ends and be electrically connected.But this terminal structure is comparatively complicated, is through repeatedly processing, make cost higher, and terminal is when compressing mutually, and elastic arm is shorter, makes it to be easy to fatigue rupture.

Therefore, be necessary to design a kind of novel terminal, to overcome above-mentioned defective.

[summary of the invention]

The purpose of this utility model is to provide a kind of terminal, and it is simple in structure, and elasticity is better, is easy to guarantee and docks electronic building brick electrically connect preferably.

For achieving the above object, the utility model terminal, it comprises fixed part, main part from the extension of fixed part one side, the top of main part is extended obliquely and is provided with connecting portion, the connecting portion end has oppositely to extend upward and is provided with elastic portion, and the elastic portion end is provided with contact site, to compress contact mutually with the butt joint electronic building brick.

Compare with prior art, the utility model terminal structure is simple, be easy to processing, and elastic arm is longer, is easy to keep better elasticity, has guaranteed to electrically connect preferably with the butt joint electronic building brick.

[embodiment]

Below in conjunction with accompanying drawing the utility model terminal is further detailed.

As shown in Figure 3, Figure 4, the utility model terminal comprises fixed part 1, main part 2 from the extension of fixed part 1 one sides, the top of main part 2 is extended obliquely and is provided with connecting portion 3, connecting portion 3 ends oppositely extend upward and are provided with elastic portion 4, elastic portion 4 ends are provided with contact site 5, to compress contact mutually with butt joint electronic building brick (not drawing among the figure).

Wherein, the top of fixed part 1 extends upward and is provided with linking arm 10, and to connect strip (not drawing among the figure), its lower end is provided with weld part 11, to weld mutually with circuit board (not drawing among the figure).

During installation, earlier terminal is fixed in the insulating body 6, it is fixed in by its fixed part 1 in the holding tank 61 of insulating body 6, and is then that terminal and circuit board (not drawing among the figure) welding is fixing.During use, to dock electronic building brick (not drawing among the figure) presses from top to bottom, reach with the contact site 5 of elastic portion 4 ends and to be electrically connected, at this moment, terminal will be subjected to a downward pressure, produce elastic deformation, because this terminal fixed part 1 and main body 3 are roughly at grade, the length of elastic arm is connecting portion 3 and elastic portion 4 length sums, so under the highly certain prerequisite of insulating body 6, the elastic arm of terminal can be very long, so the elasticity of the terminal elastic portion 4 when pressurized produces strain is better, fatigue strength is bigger, be difficult for to produce plastic deformation, makes terminal and to dock the electronic building brick electric connection preferable, guaranteed to be electrically connected preferably performance, simultaneously, this terminal structure is simple, is easy to processing.

Figure 5 shows that another embodiment of the utility model terminal, this terminal elastic portion 4 ' free terminal so that have bigger distance between the terminals of adjacent contact site 5 ', is avoided the phenomenon that is short-circuited towards lopsidedness.
