The utility model content
The utility model technical problem to be solved is: a kind of binding post is provided, and this binding post is difficult for causing loosening or loose contact problem.
For solving the problems of the technologies described above, the utility model adopts following technical scheme.
A kind of binding post comprises wiring construction, fixed structure, Welding Structure; Said wiring construction, fixed structure, Welding Structure are fixedly connected sequentially; Said wiring construction is first cylinder, and the upper bottom surface of said first cylinder is provided with screwed hole, and the side of first cylinder is provided with the wiring hole that penetrates first cylinder; Said fixed structure is the second coarse cylinder of side; Said Welding Structure is the 3rd cylinder that is weldingly connected with pcb board.
As a kind of preferred version of the utility model, said wiring hole is that diameter is the circular hole of 4.5mm.
As the another kind of preferred version of the utility model, said screwed hole is for compressing the M4 screwed hole of wire rod in order to installing M 4 screws.
As another preferred version of the utility model, said first cylinder is square body or cylinder.
As another preferred version of the utility model, the diameter of said second cylinder is 5mm.
As another preferred version of the utility model, the side of said second cylinder is covered with sawtooth.
The beneficial effect of the utility model is: it is simple, fastening firm that installation procedure is lived in the described wiring of the utility model, is difficult for causing loosening or loose contact problem, and it is little to take up room, and can satisfy the requirement of creepage distance simultaneously.

Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further explain.
Embodiment one
Present embodiment provides a kind of binding post, and is as shown in Figure 1, comprises wiring construction 1, fixed structure 2, Welding Structure 3; Said wiring construction 1, fixed structure 2, Welding Structure 3 are fixedly connected sequentially.
Respectively each structure is described in detail below:
[wiring construction 1]
Said wiring construction is first cylinder, and the side that the upper bottom surface of said first cylinder is provided with screwed hole 11, the first cylinders is provided with the wiring hole 12 that penetrates first cylinder.Said wiring hole 12 is that diameter is the circular hole of 4.5mm, and effect is client's wiring hole.The aperture of said wiring hole is all bigger than binding post aperture common on the market, makes things convenient for threading.Said screwed hole 11 is the M4 screwed hole, compresses wire rod in order to installing M 4 screws.Said first cylinder is square body or cylinder.
[fixed structure 2]
Said fixed structure 2 is the second coarse cylinder of side, and the diameter of said second cylinder is 5mm, and the side of said second cylinder is covered with sawtooth.
Said fixed structure 2 can migrate into plastic housing the inside of binding post in use, and the structure similar of the effect that prevents to come off and rotate and general copper insert has been played in coarse side.
Said second cylinder is the cylinder of cylinder or other shapes, and its shape only needs cooperate with the plastic housing of binding post and gets final product.
[Welding Structure 3]
Said Welding Structure 3 is the 3rd cylinder, and said the 3rd cylinder is that to be exposed at the plastic housing of binding post outside, and the bottom surface of the 3rd cylinder is inserted in the welding hole on the pcb board, welds with wave-soldering.
Said the 3rd cylinder is a cylinder, also can be with pcb board on the shape cylinder of welding hole form fit.
Fig. 2 is that 5 said binding posts are installed in the sketch map in the working of plastics;
Fig. 3 is that 7 said binding posts are installed in the sketch map in the working of plastics;
Fig. 4 is that 9 said binding posts are installed in the sketch map in the working of plastics;
Fig. 5 is that 13 said binding posts are installed in the sketch map in the working of plastics.
The described binding post of the utility model has the following advantages:
1) in the advantage that is embedded into aspect the binding post:
Said working of plastics is embedded into binding post in the working of plastics as inserts when injection moulding, no longer needs loaded down with trivial details work as binding post commonly used on the market.
2) advantage aspect withstand voltage:
Common binding post can't be handled the sparking problem that creepage distance causes when distance is too near, so just limited the voltage on the binding post; And the described binding post of the utility model when handling the sparking problem, adopt working of plastics with pcb board on two adjacent terminals with and tie point separate, increased the creepage distance between the sparking point like this; Shown in Fig. 2 to 7, working of plastics passes below pcb board, extends to the PCB front, and binding post penetrates downwards from the circular hole on the pcb board, and the bottom is divided into independently compartment by working of plastics, so increased creepage distance greatly.
3) advantage of construction aspect at the scene:
Common binding post site operation is the knob that directly moves the binding post top with hand-screw mostly; The suffered thrust of lead-in wire is not too big just on the binding post like this; Cause loosening or loose contact problem easily, being applied to above the high-voltage pulse main frame is exactly to cause wrong report easily; And the described binding post of the utility model has screwed hole, is fastening with screwdriver, the jail more fixing than traditional binding post.
In addition, be when binding post is a lot (two defence areas six line system pulse main frames have 13 binding posts) in the advantage that embodies aspect the construction, between the binding post or account for very big space, otherwise between distance too near; And the described binding post of the utility model makes both obtain unified satisfying, and it is little to take up room, and distance also can satisfy the requirement of creepage distance, and operation is also very convenient in addition.
Description of the utility model and application are illustrative, are not to want the scope of the utility model is limited in the above-described embodiments.Here the distortion of the embodiment that is disclosed and change are possible, and the replacement of embodiment is known with the various parts of equivalence for those those of ordinary skill in the art.Those skilled in the art are noted that under the situation of spirit that does not break away from the utility model or substantive characteristics, and the utility model can be with other forms, structure, layout, ratio, and realize with other elements, material and parts.
