CN205248476U - Circuit board constructs with external device's fast tying of circuit - Google Patents

Abstract

The utility model provides a circuit board constructs with external device's fast tying of circuit, this structure includes that it holds to set up public affairs on the circuit board, sets up female end on external device, public end can insert female end and form good contact, the circuit of equipment separately is connected respectively with female end to public end. Because public end and the connected mode of female end for pegging graft only need insert or extract female end to the public affairs end, can realize circuit board and external device's high -speed joint or dismantlement, so the installation, dismantle and maintain simple and efficient, reduce work hours, reduced working hour cost.

Description

The fast connecting structure of circuit of a kind of wiring board and external equipment

Technical field

The utility model relates to the fast connecting structure of a kind of circuit wiring board and external equipment.

Background technology

Existing wiring board is all connected by electric wire or winding displacement etc. with external equipment, and this class connected mode is because instituteMore with wire, installing and keeping in repair needs connect or disassemble compared with polylinker, and therefore installation and maintenance man-hours are longer, and cost is higher.

Utility model content

The utility model, for addressing the above problem, provides the circuit connection structure of a kind of wiring board and external equipment, subtractsLack the use of wire, can make the installation of wiring board and dismantle easy.

The utility model provides following solution: the fast connecting structure of circuit of a kind of wiring board and external equipment, itsBe characterised in that: male end is set in the circuit board, and male end is the prism that cross section is rectangle; Female end is set on external equipment, motherThe hollow prism that end is rectangle for cross section is provided with shell fragment on two faces on long limit, hollow prism cross section; Male end can be insertedEnter female end and form good contact; Male end is connected respectively the circuit of equipment separately with female end.

The beneficial effects of the utility model are, only male end need to be inserted to female end, can realize fast wiring board and externalThe connection of equipment, installation and dismounting are very quick, have reduced time cost.

Fig. 2 is the front view of the fast connecting structure of circuit of wiring board of the present utility model and external equipment.

Fig. 3 is the female end A-A cutaway view of the fast connecting structure of circuit of wiring board of the present utility model and external equipment.

Detailed description of the invention

As shown in Fig. 1 ~ 3, the fast connecting structure of the circuit of wiring board of the present utility model and external equipment, at wiring board 1 circuitOn interface, weld the male end 2 that the good metal of conduction is made as copper, aluminium etc., on the circuit interface on external equipment 4, weldThe female end that the good metal of upper conduction is made as copper, aluminium etc. The external dimensions of male end 2 is equal to or slightly less than the female end 3 that matchesInside dimension, makes in the time that male end 2 is inserted female end 3, at least can realize local good contact between the two. When needs are wiring board 1While being installed on external equipment 4, only male end 2 need be inserted to female end 3 can realize good and firm connection. When needs are circuitPlate 1, only need be extracted male end 2 when disassembling 4 is set from external from female end 3.

As a kind of frame mode, male end 2 can be made the prism that cross section is rectangle, and female end 3 is made cross section and is rectangularThe hollow prism of shape, the prism sectional dimension of male end 2 is equal to or slightly less than the sectional dimension of female end 3; Long in hollow prism cross sectionOn two faces on limit, be provided with shell fragment 31. In the time that male end 2 is inserted female end 3, shell fragment 3 is pressed in male end 2, realizes male end 2 with femaleGood contact between end 3.

By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited toState embodiment, as male end being arranged on external equipment, female end setting in the circuit board; Male end can make cylindrical orHollow cylinder, female end is made hollow cylinder matching with male end etc. What possess those of ordinary skill in the art knowsWithin the scope of knowledge, can also under the prerequisite that does not depart from the utility model aim, make a variety of changes, all belong to of the present utility modelProtection domain.
