Compared with the prior art, the utility model has the advantages that the structure is simple, and the wire locking force is big; various specifications of wires can be connected or exchanged according to requirements without special tools, the operation is extremely convenient, and the wire is quickly and reliably connected; the structure has excellent current loading capacity and large use flexibility and universality.
Description
Technical field
The utility model relates to the electrical connector technical field, especially a kind of quick locking mechanism of lead that is used for binding post.
Background technology
The binding post of prior art is connected with lead, main soldering, melting welding, crimping, solderless wrapped connection and insulation displacement (IDC) connected mode of adopting, wherein soldering is the modal terminating method of most convenient, it does not need special tooling, but the workman that requirement is skilled in technique ability guaranteed efficiency and quality, but be not suitable for less at interval occasion, welding manner relies on its advantage such as with low cost, easy to use to be extensive use of by people, but welding has certain requirement to operative skill, and in producing the rosin joint phenomenon takes place easily; The melting welding scope of application enlarges, and is commonly considered as the bonder terminal of " semipermanent "; The crimping widespread usage is in the cylindrical connector and rack-and-panel connector of detachable contact, and is easy to operate, connect reliably, but cost is higher relatively, needs special-purpose crimping tool just can carry out, but lower to operator's specification requirement, can obtain the result of high conformity; Solderless wrapped connection be with plain conductor tightly around the metal terminal tail end, the shape of terminal is generally square or rectangle, is applicable to the high density contact, produces operation inconvenience in enormous quantities, the scope of application is less; Insulation displacement (IDC) connected mode is used in electronic product extensively, and it is easy to operate, can form good air-tightness between terminal and the lead and contact, but this kind connected mode is not generally being used aspect the big current delivery.
Along with technical development and user's request, people have invented new side connecting conductor formula, by a locking spring coil lead is connected fast with metal terminal, and Fast Installation simple, the scene of can realizing is made, assembled to part easily.But Problem of Failure often takes place in this connected mode when connecting than heavy gauge wire, after lead locking, takes place that lead breaks away from or lead such as pulls out easily at phenomenon.
The utility model content
The purpose of this utility model is the quick locking mechanism of a kind of lead that designs at the deficiencies in the prior art, it adopts the lead locking mechanism of tension disc and stage clip, realize that binding post is quick with lead, reliably be connected, and it is simple in structure, easy to operate, have good current carrying capacity, do not need special tooling, have greater flexibility and popularity in use.
The purpose of this utility model is achieved in that the quick locking mechanism of a kind of lead, comprises the metal terminal that is provided with the locking wire spring coil, is characterized in that metal terminal is the butt joint that front end is made up of two contact chips, and its tail end is the tension disc that is provided with convex closure and bending; The locking wire spring coil is by locking wire window, top circular arc, connecting wall, rotation wall and support " Q " shape stage clip that planomural constitutes, and is provided with auxiliary bullet circle in the locking wire spring coil; Auxiliary bullet circle is " U " shape, is fastened on the inwall of connecting wall and rotation wall; The locking wire spring coil is installed on the tension disc, its rotation wall and support planomural and be close to bending part, and tension disc is set on the locking wire window, is held and is locked lead by the line ball section between convex closure and the bending.
Described locking wire spring coil connects locking wire window and connecting wall by the top circular arc, and connecting wall connects the rotation wall successively and supports planomural formation " Q " shape spring coil.
Described auxiliary bullet circle connects the upper support wall by circular arc wall and the lower support wall constitutes " U " shape spring coil, and it is circular-arc identical with the locking wire spring coil.
The utility model compared with prior art has simple in structure, the coupling mechanism force of lead is big, do not need special tooling, just can carry out the connection of different size lead as required or change, easy to operate, and the connection of lead is quick, reliable, and good current carrying capacity is arranged, and has greater flexibility and popularity in use.

Embodiment
Consult accompanying drawing 4, auxiliary bullet circle 3 connects upper support wall 30 by circular arc wall 31 and lower support wall 32 constitutes, by the steel band punching press, roll into " U " shape spring coil, circular-arc and the locking wire spring coil 2 of auxiliary bullet circle 3 circular-arc identical, auxiliary bullet circle 3 is positioned on the inwall of locking wire spring coil 2, its upper and lower supporting walls 30,32 and support planomural 25 and connecting wall 23 is adjacent to, upper and lower supporting walls 30,32 can deform and produces certain elastic force to center position around circular arc wall 31.
Consult accompanying drawing 5, the utility model is to use like this: before lead 4 is packed into, because the pretightning force effect of locking wire spring coil 2 itself makes locking wire window 20 on the tail end of metal terminal 1.When external force F does the time spent downwards, the distortion of locking wire spring coil 2 radial compression, locking window 20 be supports with supporting walls 25, radially rotates around rotation wall 24, is positioned at tension disc 11 lower ends at this moment and locks the open degree of window 20 and increase gradually; When locking window 20 moves down into certain displacement, when the open degree of tension disc 11 lower ends locking window 20 is enough to hold lead, lead 4 is penetrated this locking window 20, discharge external force F then, locking wire spring coil 2 radial drawing under the effect of self elastic force, make on the locking wire window 20 and move, tension disc 11 is pressed in lead 4 on the line ball section between convex closure 112 and the bending 110 tightly.Simultaneously, auxiliary bullet circle 3 has increased the coupling mechanism force of locking wire spring coil 2 under upper and lower supporting walls 30,32 common flexible supporting roles, realize the quick locking of lead 4.Repeat aforesaid operations with regard to fast changable lead 4,, just cable can be locked fast or changed fast, realize connecting reliably big current delivery in the situation that does not need special tooling.
More than just the utility model being further described, is not in order to the restriction this patent, and all is that the utility model equivalence is implemented, and all should be contained within the claim scope of this patent.
