Description

PCB wiring terminal

Technical Field

The utility model relates to an electric spare part field, in particular to PCB binding post.

Background

The existing wiring terminal for the PCB has three wiring forms: a pin type, a wire stripping locking type or a screw fixing type. The contact pin type wiring terminal can only be applied to the conditions of small voltage and current and thin wire diameter generally; compared with a pin type wiring terminal, the wire stripping locking type wiring terminal has relatively improved voltage and current, but can only connect 10 square millimeters at most, and cannot meet the wiring requirement of larger wire diameter; the requirement of bigger voltage electric current or line footpath can be satisfied to the screw fixation formula binding post, but more or less all can produce the dust and get into, and these dusts can bring very big threat for PCB and electrical components, for example the dust can produce in the electrical system operation and switch on the short circuit scheduling problem to damage components and parts or PCB board, make the product normally work, make the product scrap even.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art's the aforesaid, the utility model provides a PCB binding post, its simple structure, easy production increases protective device, guarantees the assembly environment of PCB board, can dismantle that the performance is good, convenient to use, low in production cost can protect formula PCB binding post structure.

In order to achieve the above object, the utility model adopts the following technical scheme:

a PCB terminal, comprising: the bolt fixing device comprises an insulating shell, wherein the upper end and the lower end of the insulating shell are respectively inserted with a screw combination and a nut in a threaded manner, the screw combination and the nut are connected through a conducting strip arranged on the inner side of the insulating shell, the two sides of the insulating shell are fixed through bolts, the base is hinged to an arc-shaped retaining cover I and an arc-shaped retaining cover II which are covered above the screw combination through hinge pins, and the insulating shell is provided with a plurality of radiating holes along the length direction.

Furthermore, the number of the screw combinations and the number of the nuts are respectively provided with a plurality of blocking pieces which are integrally formed and connected with the insulating shell body between the adjacent screw combinations and the adjacent nuts.

Further, the radius of the first arc-shaped blocking cover is larger than that of the second arc-shaped blocking cover.

The utility model has the advantages that:

the protective PCB wiring terminal structure is compact in structure, good in detachability, convenient to use and low in production cost, is additionally provided with a protective device, ensures the assembly environment of a PCB (printed Circuit Board), and has the advantages of good detachability

Detailed Description

The following describes the present invention with reference to the accompanying drawings. In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

In order to make the content of the present invention more clearly understood, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the attached drawings in the embodiment of the present invention.

As shown in fig. 1 to 4, a PCB connection terminal includes: the insulation shell body 1, screw combination 3 and nut 4 are inserted to the upper and lower end of insulation shell body 1 respectively screw thread, screw combination 3 and nut 4 are connected through setting up at the inboard conducting strip 2 of insulation shell body 1, bolt fastening base 6 is passed through to insulation shell body 1 both sides, base 6 keeps off lid one 8 and arc fender lid two 9 at the arc of screw combination 3 top through round pin 7 articulated lid, insulation shell body 1 is equipped with a plurality of louvre 5 along length direction.

The number of the screw assemblies 3 and the number of the nuts 4 are respectively provided with a plurality of baffle plates, and the baffle plates are integrally formed and connected with the insulating shell 1 between the adjacent screw assemblies and the adjacent nuts. The radius of the first arc-shaped blocking cover 8 is larger than that of the second arc-shaped blocking cover 9.

In the device use, its simple structure, easy production increases protective device, and arc fender lid one and arc fender lid two guarantee the assembly environment and the service environment of PCB board, but dustproof effectual, can dismantle protection formula PCB binding post structure that the performance is good, convenient to use, low in production cost.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and all modifications, equivalents, improvements and the like that are made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
