Background technology

PCB is the abbreviation of printed circuit board (PCB) (Printed Circuit Board), the PCB electronic equipment that almost we can see all be unable to do without it, little of electronic watch, calculator, general-purpose computer, large to communication apparatus, military armament systems, as long as there are the electronic devices and components such as integrated circuit, between them, electrical interconnection all will be used pcb board, and printed circuit on pcb board is through PCB binding post and the extraneous connection that is electrically connected that is connected wire.

In prior art, on some pcb boards, need to connect a plurality of PCB binding posts, each PCB binding post correspondence is connected with one and connects wire, every connect wire through branch joint be connected bus connection, in said structure, in branch joint, connect wire and the corresponding connection of separated time connecting in bus, concrete connected mode is: 1. connect wire and connect with the separated time in being connected bus through metal joint; 2. connecting wire and the injection mo(u)lding of separated time joint.But there is following some deficiency in this structure:

1. between exposed metal terminal and metal terminal, only has one deck insulating cement, in order to save wiring space and to reduce production costs, distance between adjacent metal terminal can not arrange excessive, electric clearance and creepage distance possibly cannot be guaranteed, easily electric leakage, may cause the components and parts in electrical equipment to damage, security performance is not high;

2. one deck insulating cement is set, easy to wear, cause the harmful effects such as infiltration, electric leakage.

Summary of the invention

The utility model object is to provide a kind of PCB binding post conductor structure, by using this structure, has increased electric clearance and creepage distance between circuit, has improved the fail safe of using.

For achieving the above object, the technical solution adopted in the utility model is: a kind of PCB binding post conductor structure, comprise and connect bus and at least two connection wires that are connected with PCB binding post, every described connection wire is connected with the separated time in being connected bus through metal joint, in described metal joint is provided with the junction that is connected bus, outer two-layer insulating bag glue-line, described primary insulation encapsulate layer is wrapped in outside described connection wire and described separated time, on described primary insulation encapsulate layer, between adjacent described metal joint, be provided with through hole, described outer layer insulation encapsulate layer is wrapped in outside described primary insulation encapsulate layer, and fill in described through hole.

In technique scheme, described outer layer insulation encapsulate layer is wrapped in outside described primary insulation encapsulate layer and described connection bus.

In technique scheme, described outer layer insulation encapsulate layer is provided with a plurality of anti-skidding projections, near with described bus, be connected wire connecting place and be respectively equipped with a plurality of grooves.

In technique scheme, described PCB binding post is provided with a plurality of annular lines, and described annular lines is provided with waterproof encapsulate layer outward, and parcel is to described connection wire.

Because technique scheme is used, the utility model compared with prior art has following advantages:

1. in the utility model, every connection wire is connected with the separated time in being connected bus through metal joint, and in metal joint and the junction that is connected bus, be provided with inside and outside two-layer insulating bag glue-line, on primary insulation encapsulate layer, between adjacent each metal joint, be provided with through hole, between adjacent metal joint, there are like this insulating bag glue-line and air two media, electric clearance and creepage distance have been increased, outer layer insulation encapsulate layer is filled in through hole simultaneously, electric clearance and creepage distance have further been increased, prevent electric leakage, improved the fail safe of using;

2. inside and outside two-layer insulating bag glue-line is set, has improved fastness and the water resistance of wire;

3. on PCB binding post, be provided with a plurality of annular lines, and annular lines is provided with waterproof encapsulate layer outward, and parcel is to described connection wire, annular lines coordinates with waterproof encapsulate layer, effectively increased and connected the fastness being connected between wire and PCB binding post, and promoted the water resistance of binding post;

4. on outer insulating bag glue-line, be provided with a plurality of anti-skidding projections, near with described bus, be connected wire connecting place and be respectively equipped with a plurality of grooves, anti-skidding projection has promoted the non-skid property that wire is used, the setting of groove, can effectively improve the deformation extent of outer insulation, preventing that outer layer insulation encapsulate layer is stressed causes breaking and reduces water resistance, has increased useful life;

5. the utility model is simple in structure, is easy to realize.
