Abstract

The utility model provides a make things convenient for dismouting keyboard switch, the structure exquisiteness is with low costs, and the firm connector of contact piece welding, including base and a plurality of elastic contact piece, the base includes a plurality of mounting grooves, correspond in every mounting groove and insert an elastic contact piece, elastic contact piece includes the horizontal reference face, and horizontal reference face one end is equipped with U -shaped back bending portion, and the other end is equipped with the leg. The utility model discloses the structure is exquisite, can realize the free dismouting of keyboard switch on the PCB board, and elastic contact piece is with low costs workable, and when the keyboard switch stitch moves downwards, elastic contact piece U shape back bending portion and horizontal reference face directly bear the pressure when pressing keyboard switch, and stabilizing of leg, increase of service life can be guaranteed by leg atress or not not whether.

Description

A kind of adapter

Technical field

This utility model relates to keyboard switch field, is specifically related to a kind of adapter for keyboard switch.

Background technology

Traditional keyboard switch is directly switch pedestal to be arranged on pcb board and welded by contact chip leg, after installing, switch pedestal cannot be changed, once damage and just cannot keep in repair, although there being portion keyboard to use the design of attachment means to make keyboard switch and PCB link together, the whole replacing of keyboard switch that can will damage, but structure is usually relatively complex, production and processing cost is high, if the most insecure leg that can also affect on contact chip consolidates, affect whole keyboard switch service life.

Utility model content

For the problems referred to above, this utility model provides a kind of easy disassembly keyboard switch, the adapter that delicate structure, low cost and contact chip welding are relatively firm, including base and multiple elastic contact chip, base includes multiple mounting groove, one elastic contact chip of corresponding insertion in each mounting groove, and described elastic contact chip includes level reference, level reference one end is provided with U-shaped bent back portion, and the other end is provided with leg.

Preferably, the inner bottom part both sides of described mounting groove have level trough, and the level reference both sides of described elastic contact chip are provided with and sharp teeth, described in sharp teeth and level trough interference fit, make elastic contact chip firmly be inserted in mounting groove.

Further, described leg bends vertically upward from the level reference of elastic contact chip, then horizontal buckling constitutes horizontal segment, then bending constitutes lower horizontal section vertically downward, and lower horizontal section lower end is directly interspersed in the welding hole that pcb board is corresponding.

Further, described base surrounding also includes that multiple hanging platform, described hanging platform are positioned at same level with the horizontal segment of leg.

Preferably, described base center is provided with through hole.

This utility model delicate structure, keyboard switch disassembled and assembled freely on pcb board can be realized, and elastic contact chip low cost, easily processing, when keyboard switch stitch downward actuation, elastic contact chip U-shaped bent back portion and level reference directly bear pressure during pressing keyboard switch, and leg does not stresses, can ensure that the firm of leg, increase the service life.

Detailed description of the invention

For making those skilled in the art be better understood from this utility model, below in conjunction with embodiment and accompanying drawing, this utility model is further described.

Adapter as shown in Figure 1, 2, including base 1 and 5 elastic contact chips 2, base 1 includes 5 mounting grooves 11, and one elastic contact chip 2 of corresponding insertion in each mounting groove 11, base 1 center is provided with through hole 14；Elastic contact chip 2 is as shown in Figure 3, including level reference 21, level reference 21 one end is provided with U-shaped bent back portion 22, the other end is provided with leg, described leg bends vertically upward from the level reference 21 of elastic contact chip 2, horizontal buckling constitutes horizontal segment 23 again, then bending constitutes lower horizontal section 24 vertically downward；The inner bottom part both sides of mounting groove 11 have level trough 12, and level reference 21 both sides of elastic contact chip 2 are provided with and sharp teeth 25, described in sharp teeth 25 with level trough 12 interference fit, make elastic contact chip firmly be inserted in mounting groove.

As shown in Fig. 4,5,6, base 1 surrounding also includes multiple hanging platform 13, described hanging platform 13 is positioned at same level with the horizontal segment 23 of leg, make adapter can insert in pcb board 3 in heavy plate mode, hanging platform 13 and horizontal segment 23 can be attached to pcb board surface, adapter is made to be horizontally positioned on pcb board, the hole that the lower horizontal section 24 of leg is inserted through on pcb board is stretched out on pcb board ground, in order to carry out wave soldering；The stitch of keyboard switch 4 can be pushed down the U-shaped bent back portion 22 of elastic contact chip downward vertically and keep Elastic Contact, the pressing piece 41 of keyboard switch 4 can move up and down in through hole 14, owing to level reference 21 is fixed in level trough, horizontal segment 23 and the lower horizontal section 24 of elastic contact chip 2 is not interfered with after U-shaped bent back portion 22 stress, therefore, during the use of keyboard switch, leg still can very firmly link together with pcb board.

Above-described embodiment generally with the keyboard switch of pin lamp with the use of, be illustrated in figure 7 another embodiment of adapter, including base 1 and 2 elastic contact chips 2, the keyboard switch of usual and SMD lamp with the use of.

Above-described embodiment is only preferred embodiment of the present utility model, and it describes more concrete and detailed, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these obvious alternative forms belong to protection domain of the present utility model.
