Description

A kind of binding post that is applied to the PCB circuit board

Technical field

The utility model relates to a kind of binding post, particularly a kind of binding post that is applied to the PCB circuit board.

Background technology

Common binding post is after inserting conductor wire, can realize that circuit communication uses by the bolt binding post, but the binding post in being applied to PCB wiring board, surface-mounted integrated circuit then leaves leg, binding post need be welded on the circuit board by leg during use.So the someone has designed a kind of binding post that can adapt to printed substrate, relate to the connector of circuit as Chinese utility model ZL90225748.X " binding post ", the binding post that is electrically connected with printed circuit board (PCB) especially for external circuit.Form by plastics terminal, lug plate, lug plate plane groove, pad, spring washer and screw etc., it is characterized in that having on the plastics terminal protruding pullover, have shape similarly and can hold protruding pullover groove, the groove that can hold the lug plate plane is arranged again and can hold the groove of lug plate leg, and have an aperture to communicate between two grooves.The binding post volume is small and exquisite, can be in a row by the single-piece combination in any as required, be widely used in various electronic instruments, Machine Tool Electric Appliance, controller, Digit Control Machine Tool and automation equipment.But, it all is by manual the terminal leg to be welded among the circuit that general this terminal connects, the efficient of this manual welding mode in integrated circuit manufacturing or monster chip production process is too low, does not fit into automated production, awaits to do further improvement.

Summary of the invention

Technical problem to be solved in the utility model is that a kind of binding post that is applied to the PCB circuit board that can be convenient to the automation assembling is provided at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this is applied to the binding post of PCB circuit board, include housing and the weld tabs that is arranged in this housing, wherein, described housing includes the lead patchhole, it is characterized in that: also include one and can be plugged on the automatic assembling cover plate that described lead inserts in the hole, this is assembled cover plate automatically and has and suitable pin of described lead patchhole and and the adsorption plane that is connected together of this pin.

In order to allow pin have certain elasticity and tension force, make that the assembling cover plate has fixedlying connected property preferably with terminal shell automatically, described pin has the U-shaped open slot, this pin is two free ends with elasticity distance at the U-shaped opening part, thus, two free ends of pin can be close because be squeezed after inserting the conduction patchhole, also can produce a bounce simultaneously and pin inserted in the hole at lead strut, and prevents that pin from becoming flexible and drop out the lead patchhole.

Described housing can have one, the lead patchhole of two or more, can be plugged on the pin that arbitrary described lead inserts in the hole as long as described automatic assembling cover plate includes at least one, just can realize assembling automatically being connected of cover plate and housing.

Compared with prior art, advantage of the present utility model is: the concrete structure of mating terminals housing, set up an automatic assembling cover plate that can plug with the housing lead patchhole of this terminal, automatically the assembling cover plate has the pin that can insert the lead patchhole, and pin has is with flexible U-shaped open slot, can realize assembling automatically the connection compactness between cover plate and the housing preferably, so, when the PCB circuit board terminals connects, automatically the pin of assembling cover plate can be inserted in the lead patchhole of terminal shell, hold the adsorption plane of automatic assembling cover plate by the automatic assembling suction nozzle, just whole terminal shell can be mentioned, and be welded on the circuit board, thereby the binding post of realizing automation is assembled.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Embodiment, referring to Fig. 1～Fig. 6:

The utility model relates to a kind of binding post of the PCB of being applied to circuit board, comprise the housing of forming by a plurality of connecting portions that can independently splice 11 1, one side of housing 1 is a closed end cap 2, have lead patchhole 111 in each connecting portion 11 upper end, be provided with conduction weld tabs 3 in each connecting portion 11, the end of weld tabs 3 is stretched out and is formed leg 31 outside the housing 1, as shown in Figure 1, each connecting portion 11 also has the button 5 that offsets with weld tabs 3, presses this button 5 and the lead of being lived by weld tabs 3 compactings can be extracted from lead patchhole 111 again.The mounting means of this binding post concrete structure and weld tabs is a prior art, is not summary of the invention of the present utility model, does not do detailed argumentation at this.

In order to realize the automation assembling of binding post when the PCB circuit board connects in the present embodiment, replace original manual welding mode of using to realize the assembling of terminal on circuit board, present embodiment has designed an automatic assembling cover plate 4 in the lead patchhole 111 that can be plugged on any one connecting portion, automatically assembling cover plate 4 have with the suitable pin 41 of lead patchhole 111 and and the adsorption plane 42 that is connected together of this pin 41, as shown in Figure 2.

Wherein, described housing 1 can have one, the lead patchhole 111 of two or more, how much relevant the connecting portion 11 of the quantity of lead patchhole 111 and binding post combination itself is, as long as include at least one and can be plugged on pin 41 in arbitrary described lead patchhole 111 and assemble cover plate 4 automatically, just can realize assembling automatically being connected of cover plate 4 and housing 1, binding post as present embodiment has four lead patchholes 111, so automatically, assemble cover plate 4 and can have one, two, three or four can with the suitable pin 41 of the lead patchhole 111 on the housing 1, automatic assembling cover plate in the present embodiment has two pins 41 that are provided with at interval, referring to Fig. 4, Fig. 6.

In order to allow pin 41 have certain elasticity and tension force, make that assembling cover plate 4 has fixedlying connected property preferably with terminal shell 1 automatically, each pin 41 all has the open slot 411 of U-shaped, as Fig. 3, shown in Figure 5, each pin 41 is two free ends 412 with elasticity distance at U-shaped open slot 411 places, in U-shaped open slot 411, also be provided with reinforcement 413, thus, two free ends 412 of pin 41 can be close because be squeezed after inserting conduction patchhole 111, simultaneously also can be because of the supporting role of reinforcement 413, produce a bounce and pin 41 is strutted in lead patchhole 111, prevent that pin 41 is loosening and drop out lead patchhole 111.

During use, can on terminal shell 1, install automatic assembling cover plate 4 earlier, automatically the pin 41 of assembling cover plate 4 is inserted in the lead patchhole 111 of housing 1 upper end, can hold the adsorption plane 42 of automatic assembling cover plate 4 then by the automatic assembling suction nozzle, just whole terminal shell 1 can be picked up, can binding post be put on the PCB circuit board automatically by manipulator like this, thereby realize the automation assembling, improve production efficiency greatly.
