Abstract

A direct insert type connection terminal comprises an insulating seat (1) provided with a jack (11) and a conducting sheet metal (2) arranged inside the insulating seat (1), wherein, one end of the conducting sheet metal (2) is provided with a pair of opposite spring plates (21) which extend into the jack (11) of the insulating seat (1); moreover, the tops of the spring plates (21) are provided with opposite flanges (21a); the other end (22) of the conducting sheet metal (2) is inserted with a screw (3) to fasten an external conducting wire. Compared with the prior art, the shrinking openings formed at the tops of the spring plates prevent the PCB board inserted between the spring plates from breaking off easily; therefore, the insertion between the PCB board and the utility model is firmer so as to prevent the PCB board from separating from the connection terminal; meanwhile, the PCB board can be inserted into the connection terminal more conveniently; moreover, the utility model ensures excellent electric conduction of the conducting terminal of the PCB board and the conducting sheet metal.

Description

A kind of direct insertion binding post

Technical field

The utility model relates to the technical field of binding post, especially refers to a kind of direct insertion binding post.

Background technology

At present, have the various connection PCB plate (abbreviations of Printed Circuie Board that are used on the market, mean the epoxy printed circuit board (PCB)) direct insertion binding post, be that the Chinese utility model patent " fixed connection terminal " of ZL200520013342.3 (publication number is CN2821904Y) discloses a kind of comparatively general binding post as the patent No..It includes pedestal, pedestal is provided with the equidistant parallel partition, forms insulating base between two partitions, and conductive metal sheet is installed in the insulating base, one end of this conductive metal sheet is connected with the screw of fastening outer lead, and the other end is provided with the inserted sheet that cooperates with the inner lead end.Because the inserted sheet on its conductive metal sheet is simple sheet, during actual the use, after the conducting terminal of pcb board is inserted in the insulating base, loosening phenomenon takes place in this pcb board jack easy and insulating base, even separate with the inserted sheet of this sheet and spin off from binding post, therefore, this conductive metal sheet can not guarantee that the good of its inserted sheet of conducting terminal and this of pcb board contacts, thereby guarantee the electrical connection that both are good, sometimes in order to prevent that pcb board from loosing from binding post, the conducting terminal of pcb board and the conductive metal sheet in this insulating base need be welded, very trouble is not only time-consuming but also require great effort.

On the other hand, existing direct insertion binding post, the binding post that comprises above-mentioned patent, only simple at the two ends of insulating base and relatively this insulating base is vertical offers fixing hole, binding post wears fixing hole by screw and can only take place to fix at direction and the pcb board that insulating base is vertical relatively, and in actual use, multi-faceted vibrations can make pcb board loose from binding post, therefore, this binding post needs 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 direct insertion binding post, make pcb board thereon to plug operation more convenient, can guarantee electric good conducting, and the grafting of pcb board and this direct insertion binding post is more firm.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this direct insertion binding post, include the insulating base of band jack and be arranged on the interior conductive metal sheet of insulating base, wherein, this conductive metal sheet one end extend in the jack of described insulating base, the other end then is equipped with the screw of fastening outer lead, it is characterized in that: that end that extend on the described conductive metal sheet in the insulating base jack is provided with relative a pair of shell fragment, the relative flange that is provided with on this top to shell fragment.

For strengthening this to the clamping action of shell fragment to conducting terminal on the pcb board, the external diameter at the described shell fragment top external diameter than its bottom slightly is little, also be that this top to shell fragment is drawn close slightly mutually, leave the space that expands outwardly between this jack like this to the top of shell fragment and insulating base, in the conducting terminal on the pcb board is inserted into this insulating base jack this to shell fragment in the time, this can expand outwardly in jack slightly to shell fragment, and when pcb board on this binding post, plug finish after, this top to shell fragment just reverts to original state, promptly draw close slightly mutually and form a less reducing, the buckle of conducting terminal on the pcb board and binding post is just more firm like this, be not easy to take place the situation that both arbitrarily break away from, and pcb board to plug operation also more convenient.

On the general binding post, the direction of vertically insulated seat offers first fixing hole at the two ends of insulating base, for preventing in multi-faceted vibrations process, pcb board looses from binding post, the two ends of the described insulating base direction vertical with described first fixing hole can also offer second fixing hole, further strengthens the fix tightly soundness of binding post on pcb board.

Compared with prior art, advantage of the present utility model is: by to carry out the design of shell fragment of symmetry on the conductive metal sheet with the coupling part of pcb board conducting terminal, and flange is set and forms a reducing relatively at the top of shell fragment, make and be inserted into this and can not spin off easily the pcb board between the shell fragment, make the grafting of pcb board and this direct insertion binding post more firm, thereby preventing that pcb board from getting loose with this binding post separate; Simultaneously, by on the conductive metal sheet this to shell fragment, make pcb board on binding post to plug operation also more convenient, and can guarantee the conducting terminal and the good electrically conducting of this conductive metal sheet of pcb board; The utility model is simple in structure, uses efficient and conveniently, and is easy to processing and manufacturing.
