Abstract

A high power wiring connecting terminal for printed circuit board comprises a bottom support and a top support which are connected via columns. The high power wiring connecting terminal can satisfy the demands of high power, improve the mechanical strength of printed circuit board and improve application safety, with easy manufacture, low cost, high safety and easy usage, which is suitable for the conditions with high current on circuit board and the requirement on high mechanical strength.

Description

The high-power binding post of use in printed circuit board

Technical field

The utility model relates to a kind of termination that is used for printed circuit board (PCB).

Background technology

Sometimes need the big electric current of input or output on the printed circuit board (PCB), current strength may reach dozens or even hundreds of ampere.Existing way is to stay the through hole of a M8 or M10 on printed circuit board (PCB), uses screw bolt and nut that the wiring nose is fixed on the printed circuit board (PCB).Though this way has solved the connection of circuit and has realized that printed circuit board (PCB) ruptures because of the extruding of screw bolt and nut through regular meeting in actual applications, threatens the attachment security of circuit board and cable, stays potential safety hazard.The electric current of termination is big electric current owing to flow through, once because the extruding of screw bolt and nut makes printed circuit board (PCB) produce fracture, will have serious consequences.

Summary of the invention

For avoiding the issuable serious consequence of prior art, the utility model develop a kind of safe, cost is low and the high-power binding post of use in printed circuit board that is easy to make.

Its technology realizes that means are as follows: comprise the bottom support, the top support that are installed in the printed circuit board (PCB) upper and lower surface respectively, six stupefied posts are arranged on the bottom support of printed panel lower surface, six stupefied height of column are greater than the thickness of printed circuit board (PCB), and the bottom carriage center has bottom carriage center through hole; The top support rack type of printed panel upper surface is like bolt, and there is through hole at the center, is provided with cylinder below the support of top, and the cylinder external diameter equals bottom carriage center through-hole diameter, and damaged surface to be processed into vertical bar stupefied.

The beneficial effects of the utility model are: it comprises top support and bottom support composition, has born the pressure of screw bolt and nut fully, and the protection circuit plate is without prejudice, and has improved fail safe.And be easy to make, cost is low, is applicable to connect on printed circuit board (PCB) to draw big electric current.

Description of drawings

Fig. 1 is the structure chart of the utility model bottom support.

Fig. 2 is the structure chart of the utility model top support.

Fig. 3 is an assembling design sketch of the present utility model.

In the drawings: 1, bottom support, 2, the top support, 3, six stupefied posts, 4, vertical bar is stupefied, 5, bottom carriage center through hole.

Embodiment

The utility model comprises bottom support 1, the top support 2 that is installed in the printed circuit board (PCB) upper and lower surface respectively, makes from the pressure of screw bolt and nut and is all born by support; The similar nut of bottom support of printed panel lower surface has six stupefied post 3, six stupefied height of column to be greater than the thickness of printed circuit board (PCB), and top support 2 types of printed panel upper surface are like bolt, and the bottom carriage center has bottom carriage center through hole 5; Top support 2 types of printed panel upper surface are like bolt, and there is the through hole of M10 at the center, are provided with cylinder below the top support 2, and the cylinder external diameter equals bottom carriage center through hole 5 diameters, and damaged surface is processed into vertical bar stupefied 4.

Bottom support 1 is connected and fixed by the six stupefied posts 3 that distribute on the bottom support 1 with printed circuit board (PCB), makes bottom support 1 be fixed on circuit board one side.The existence of six stupefied posts 3 makes bottom support 1 and top support 2 be fixed on the printed circuit board (PCB) firmly; Increase the contact area with printed circuit board (PCB), made the cross-sectional area of electric current increase; Six stupefied posts 3 have supported top support 2 in the process of tight bolt, thereby have born whole pressure of screw bolt and nut, have protected printed circuit board (PCB).Top support 2 does not directly contact with circuit board, and the external diameter of top support 2 cylinders equals the internal diameter of bottom carriage center through hole 5, uses mechanical external force that top support 2 is pressed into bottom carriage center through hole 5, up to closely contacting with bottom support six distracted posts 3.Vertical bar on the support cylinder of top is stupefied 4, makes that the elasticity of metal surface is better.Insert in the process of pressing in external force, destroyed the oxide-film of metal surface, make the bottom support tightr with contacting of top support.

When making printed circuit board (PCB), except the regulation wiring position, outside the bolt specification, also will be for 12 six on the support of bottom stupefied post 3 default via holes, the diameter of via hole will with the equal diameters of six stupefied post circumscribed circles.In the process of installing, at first 12 six on the support of bottom stupefied posts 3 are pressed into from the default via hole of circuit board, make on the stupefied via hole that is stuck in printed circuit board (PCB) tightly of six stupefied posts 3 with external force.And then use external force, with the top support 2 slotting bottom carriage center through holes 5 of compressing into.In use screw is inserted from bottom carriage center through hole 5, the other end inserts wiring nose and nut, tightens to get final product.Safe in utilization, connect reliable.

Claims (1)

1, the high-power binding post of a kind of use in printed circuit board, it is characterized in that: comprise the bottom support (1), the top support (2) that are installed in the printed circuit board (PCB) upper and lower surface respectively, six stupefied posts (3) are arranged on the bottom support (1) of printed panel lower surface, six stupefied height of column are greater than the thickness of printed circuit board (PCB), and there is bottom carriage center through hole (5) at bottom support (1) center; Top support (2) type of printed panel upper surface is like bolt, and there is through hole at the center, and the top support is provided with cylinder below (2), and the cylinder external diameter equals bottom carriage center through hole (5) diameter, and damaged surface is processed with vertical bar stupefied (4).
