Abstract

The utility model provides a connection structure for a wire and a binding post. The connection structure comprises a wire, a binding post and a connection component, wherein the binding post is connected with a battery cover body through glass in a sealed manner; a thread is turned on the upper part of the binding post; a contact platform is arranged at the sealing root of the battery cover body; the wire is connected with the binding post through the connection component; the connection component sequentially comprises a flat gasket, a wiring terminal, a spring gasket and a self-locking nut from bottom to top; and the wiring terminal is connected with the wire in a cold-pressing manner. The connection structure has the advantages that the shortcomings of the conventional welding method under a high temperature environment are overcome; the reliability of long-time work of a thermal battery in a high-temperature environment and a severe dynamic condition is effectively guaranteed; and a requirement on long-time reliable work of the battery in the environment with temperature of 400 DEG C and under the severe dynamic condition is met.

Description

The syndeton of a kind of wire and binding post

Technical field

The utility model relates to the thermal cell technical field, particularly relates to the syndeton of a kind of wire and binding post.

Background technology

The hot environment working temperature of thermal cell generally is no more than 70 ℃, and the battery binding post is at binding post with being connected of wire and punches traditionally, and wire penetrates rear employing soldering mode and connects (seeing Fig. 1), can satisfy long electric current output fully.And present development along with the thermal cell technology, the range of application of thermal cell is also in continuous expansion, the requirement that the hot environment working temperature is existing 400 ℃, because common scolding tin fusing point is about 180 ℃, high temperature scolding tin fusing point does not all satisfy 400 ℃ high temperature requirement about 220 ℃, if binding post is connected the soldering mode that still adopts with wire, just do not satisfy the requirement of long-time hot operation, must change the conventional method of attachment of wire and binding post this moment, adopts mechanical system to connect.

Summary of the invention

The utility model embodiment generally is no more than 70 ℃ defective for the hot environment working temperature that solves thermal cell in the prior art, the syndeton of a kind of wire and binding post is provided, comprise wire, binding post and coupling assembling, described binding post is connected by glass sealing with battery cover, described binding post top car has screw thread, with have one to contact platform on the root of battery cover sealing-in, described wire is connected coupling assembling with binding post and connects, described coupling assembling is followed successively by plain washer from bottom to up, binding post, spring washer and self-locking nut connect described wire on the described binding post.

Described binding post adopts to cold pressing with described wire and is connected.

Described contact podium level scope is 2mm-4mm.

The present invention's beneficial effect compared with prior art:

The utility model changes binding post into special-shaped binding post by design, machining screw on binding post, and keep the contact platform of certain altitude at root, binding post with holes wire termination crimping and the binding post diameter of thread are complementary tightens together binding post and binding post again with self-locking nut, plain washer and spring washer.The contact platform guarantees and the good contact on binding post plane on the one hand, makes on the other hand binding post and battery cover surface that certain distance is arranged, and guarantees insulating properties between each binding post.Wire adopts the mode of colding pressing to be connected with binding post simultaneously, but the job requirement of withstand high temperatures environment and harsh mechanical condition.This structure is general, simple, avoided the defective of former welding manner in hot environment, effectively guarantee the reliability that thermal cell works long hours under hot environment and harsh mechanical condition, can satisfy the requirement of long-time reliably working under 400 ℃ of hot environments of battery and the harsh mechanical condition.

Embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.

Be illustrated in figure 3 as the syndeton schematic diagram of a kind of wire of the utility model and binding post, comprise wire 5, binding post 1 and coupling assembling, described binding post 1 is connected by glass sealing 2 with battery cover 3, the structural representation of described binding post 1 as shown in Figure 2, described binding post 1 top car has screw thread, with have one to contact platform 6 on the root of battery cover 3 sealing-ins, described contact platform 6 altitude ranges are 2mm-4mm.Described wire 5 is connected with binding post and is connected by coupling assembling, described coupling assembling is followed successively by plain washer 9, binding post 7 from bottom to up, spring washer 8 and self-locking nut 10, connect described wire 5 on the described binding post 7, the two is owing to connecting by the mode of colding pressing, by the actual verification examination, can satisfy the requirement of long-time reliably working under 400 ℃ of hot environments of battery and the harsh mechanical condition.

Above-described embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is embodiment of the present utility model; and be not used in and limit protection range of the present utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
