Description

A kind of binding post that is used for the connection PCB plate

Technical field

The utility model relates to the technical field of binding post, especially refers to a kind of binding post that is used for connection PCB plate (being printed circuit board (PCB)).

Background technology

At present, generally on the market be used for the (abbreviation of Printed Circuie Board of connection PCB plate, mean the epoxy printed circuit board (PCB)) binding post, include the plastic cement body of band pcb board jack and wire jack, be arranged on the conducting strip in the plastic cement body pcb board jack, be plugged in the terminal clamp body of intrinsic screw of plastic cement and band center through hole, wherein, the wire jack of plastic cement body communicates with the center through hole of terminal clamp body, conducting strip bottom in the pcb board jack extends downwardly in the center through hole of terminal clamp body, and, orthogonal being threaded of sidewall of screw and terminal clamp body, and make the terminal clamp body can be along this screw move left and right, like this, conducting terminal on the pcb board is inserted in the pcb board jack of plastic cement body, lead then is inserted in the wire jack of plastic cement body accordingly, and rotary screw makes terminal clamp body be moved to the left along this screw, thereby conducting strip and lead are fitted tightly, realize pcb board, conducting strip, lead the three be electrically connected mutually.

Because only need being communicated with the center through hole of pcb board jack and terminal clamp body, conducting strip wherein gets final product, its general making in the form of sheets, like this, the pcb board jack still is a circular hole substantially, during actual the use, loosening easily between the conducting terminal of pcb board and this pcb board jack, the good electrical that can not guarantee both connects, sometimes in order to prevent that pcb board from loosing from binding post, the conducting terminal of pcb board and the conducting strip in this pcb board jack need be welded, very trouble is not only time-consuming but also require great effort, therefore, need further improvement.

Summary of the invention

Technical problem to be solved in the utility model is that the present situation at prior art provides a kind of binding post that is used for the connection PCB plate that operation is more convenient, guarantee electric good conducting that plugs that makes pcb board.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this is used for the binding post of connection PCB plate, include the insulating body of band pcb board jack and wire jack, conducting strip, be plugged in screw and the terminal clamp body of being with center through hole in the insulating body, wherein, the wire jack of described insulating body communicates with the center through hole of terminal clamp body, described conducting strip comprises the top that is positioned at the pcb board jack and is positioned at the lower part of terminal clamp body center through hole, and, orthogonal being threaded togather of sidewall of screw and terminal clamp body, it is characterized in that: the top of described conducting strip has relative a pair of shell fragment, this adapts to the spacing of shell fragment and the size of described pcb board jack, and the lower part of described conducting strip is the L type, the lateral part of this L type lower part links to each other with the bottom of described shell fragment, and vertically part then is applied in the center through hole of described terminal clamp body.

Because after lead is inserted in the center through hole of terminal clamp body, lead just is folded between the center through hole sidewall of the vertical part of conducting strip L type lower part and terminal clamp body, it is tight more that the lower part of conducting strip and lead are fitted, just can guarantee the good conducting of conducting strip and lead more, therefore, vertically can be provided with a plurality of grooves on the medial surface of part in the L type lower part of described conducting strip, like this, on the one hand by strengthening the friction between conducting strip and the lead, can prevent that lead from coming out from slippage between the center through hole sidewall of the vertical part of this L type lower part and terminal clamp body, on the other hand, guaranteed the good conducting of conducting strip and lead.

Pcb board sometimes has fixing lug boss, and the insulating body smooth outer surface of present existing binding post, can not utilize the fixing lug boss on the pcb board and pcb board is buckled on the insulating body, for preventing that further this pcb board from getting loose from binding post, can be provided with L type trip on the described insulating body outer surface, during actual the use, just match with fixing lug boss on the pcb board in the lateral part on L type trip top, and make the mutual buckle of fixing lug boss that trip can be on pcb board, so in use, run into adverse circumstances such as multidirectional vibrations, the assurance binding post also can be realized being electrically connected reliably, has improved the reliability of binding post.

In addition, buckle binding post is together disassembled from pcb board for convenient, the top of described trip can be provided with breach, like this, when needs are changed binding post, only need with supporting instrument, stretch in the breach of this trip and stir trip, just can be easily the fixing lug boss of pcb board be separated from trip, makes disassembling section become convenient, flexible.

Compared with prior art, advantage of the present utility model is: by particular design to conducting strip, the elastic force folder that forms on conducting strip top, make pcb board to plug operation more convenient, the user can fast binding post be assembled on the pcb board, and guarantee electric good conducting; Simultaneously, the design of L type trip on the binding post outer surface makes the fixed installation of the pcb board of band fixing lug boss become firm more, reliable; The utility model is simple in structure, uses efficient and conveniently, and is easy to processing and manufacturing.
