Abstract

The invention discloses a wire connecting terminal preventing a wire clamping end from rotating, and is characterized in that a cross-teeth nut and a convex platform are arranged on the wire connecting end surface of a conducting strip, and the cross-teeth nut and the conducting strip are connected in a riveting manner; the convex platform is arranged at the two ends or the middle of one side of the conducting strip, and is shaped together with the conducting strip during punching; the wire clamping end is a wire beezer provided with a square through-hole; the wire clamping end is sleeved in the convex platform at the two ends of the conducting strip or the convex platform in the middle of the conducting strip is sleeved in the square through-hole; the wire clamping end is fixedly contacted with the conducting strip via the threaded connection between a screw component and the cross-teeth nut; and the convex platform is used for limiting the rotation of the wire clamping end on the conducting strip. Compared with the prior art, the wire connecting terminal provided by the invention is simple in structure and convenient to mount, can effectively prevent an OT terminal from rotating, greatly lowers invalidation of the connecting of cables, and improves the safety and the reliability of the transmission of a circuit.

Description

The binding post that a kind of anti-sticking line end rotates

Technical field

The present invention relates to electric components interconnection technique field, especially a kind of binding post that is applicable to the anti-sticking line end rotation of OT terminal.

Background technology

At present; In the interconnection of electronic circuit, there is considerable occasion to realize compiling of electric current or shunt with binding post, but along with the development of device miniaturization; The integrated degree of the last components and parts of PCB is increasingly high; This just makes and can cable be fastenedly connected after the binding post wiring that prevent that effectively the rotation of OT terminal from just seeming particularly important, it will directly influence the final performance of whole transmission circuit.

The binding post of prior art relies on and strengthens torsion when installing, and OT terminal is not rotated, and realizes that the OT terminal installation is firm; The initial stage performance after installation of this fastening means is reliable; But along with the growth of service time, promptly under the effect of gravity or external force, cable can destroy device on every side along moved by force direction; Exist cable and connect the hidden danger that lost efficacy, influence the safety and the reliable transmission of circuit.

Summary of the invention

The binding post that a kind of anti-sticking line end that the objective of the invention is to design to the deficiency of prior art rotates, the boss that its adopts conducting strip drawing be with fixing OT terminal, can cable be fastenedly connected after making terminal connections; Effectively prevent the rotation of OT terminal; Realize the function of protection peripheral devices, simple in structure, easy for installation; Can satisfy the on-the-spot needs of installing easily and fast, improve the fail safe and the reliability of circuit transmission greatly.

The objective of the invention is to realize like this: the binding post that a kind of anti-sticking line end rotates; Comprise that card line end, screw assembly, nut and cross section are the conducting strip of " U "; The wiring end face that is characterized in conducting strip is provided with colored teeth nut and boss; The flower teeth nut is that riveting is connected with conducting strip, and boss is arranged on the two ends of conducting strip one side or the centre of a side, and boss is shaped when being the conducting strip punching press; Block the line nose that line end is or establishes square through hole; The card line end is sleeved in the boss at conducting strip two ends or the boss in the middle of the conducting strip is set in the square through hole, and being threaded by screw assembly and flower teeth nut contacts card line end and conducting strip are fastening, and boss limits and blocks line end and on conducting strip, rotate.

The present invention compared with prior art has simple in structure, and is easy for installation, can effectively prevent the rotation of OT terminal, reduces the inefficacy that cable connects greatly, improves the fail safe and the reliability of circuit transmission.

Embodiment

Consult accompanying drawing 1～accompanying drawing 3; The present invention includes card line end 2, screw assembly 3, nut 5 and cross section and be the conducting strip 4 of " U "; The wiring end face of conducting strip 4 is provided with colored teeth nut 5 and boss 6; Flower teeth nut 5 and conducting strip 4 are for riveting is connected, and boss 6 is arranged on the two ends of conducting strip 4 one sides or the centre of a side, and boss 6 is shaped when being conducting strip 4 punching presses; Block the line nose that line end 2 is or establishes square through hole 8; Boss 6 boss 6 interior or conducting strip 4 centres that card line end 2 is sleeved on conducting strip 4 two ends are set in the square through hole 8; Be threaded card line end 2 and conducting strip 4 fastening contacts with flower teeth nut 5 by screw assembly 3, boss 6 restriction card line ends 2 rotate on conducting strip 4.

Consult accompanying drawing 4～accompanying drawing 6; The wiring end face of conducting strip 4 is provided with boss 6 and screw 7; Boss 6 is arranged on the two ends of conducting strip 4 wiring end faces one side; Once-forming when boss 6 is punching press with conducting strip 4, two boss 6 form a gap on the wiring end face of conducting strip 4, with the left-right rotation of restriction card line end 2 on conducting strip 4.

Consult accompanying drawing 7, card line end 2 is for establishing the line nose of square through hole 8 and connecting hole 10.

Consult accompanying drawing 8; The present invention uses like this: the wiring handle of cable 1 heart yearn with card line end 2 is fixedly connected; The wiring handle that will block line end 2 then is fastened in the gap of 6 formation of two boss, is threaded with flower teeth nut 5 by screw assembly 3, will block line end 2 and conducting strip 4 fastening contacts; The wiring handle of card line end 2 is fastened in the gap in the middle of two boss 6; Limit the left-right rotation of card line end 2 on conducting strip 4, can not cause the connection of cable 1 to lose efficacy because of the rotation of card line end 2, reached reliable purpose of connecting.The pin 9 of conducting strip 4 flows into conducting strip 4 with PCB welding, electric current through cable 1, is diverted to PCB by the pin 9 of conducting strip 4 and goes up and realize shunting, otherwise realize confluxing.

Consult accompanying drawing 9～accompanying drawing 10; Conducting strip 4 is for the centre of wiring end face one side is provided with boss 6, and once-forming when boss 6 is punching press with conducting strip 4 is set in boss 6 in the square through hole 8 on the card line end 2; Be threaded with flower teeth nut 5 by screw assembly 3; With the card line end 2 and conducting strip 4 fastening contacts that are fixedly connected cable 1, the wiring handle of card line end 2 is fastened in the boss 6, the left-right rotation of restriction card line end 2 on conducting strip 4; Can not cause the connection of cable 1 to lose efficacy because of the rotation of card line end 2, reach reliable purpose of connecting.The pin 9 of conducting strip 4 flows into conducting strip 4 with PCB welding, electric current through cable 1, is diverted to PCB by the pin 9 of conducting strip 4 and goes up and realize shunting, otherwise realize confluxing.
