Abstract

The utility model relates to an engine end sealing ring. The sealing ring is cylindrical, a sealing face is arranged on the periphery of the sealing ring, bosses are arranged on the two sides of the sealing face, and the end face of each boss is a straight face. Due to the arrangement of the bosses and the straight faces, the sealing performance of the sealing ring is improved, and assembly can be conveniently carried out; due to the arrangement of an insertion groove with a rectangular section, end electrode terminals can be effectively prevented from falling off. As is shown in actual use, the sealing ring is significant in implementation effect.

Description

Motor terminal seal ring

Technical field

The utility model relates to a kind of motor car engine terminal zero parts, is specifically related to motor terminal seal ring, belongs to automobile technical field.

Background technique

Existing motor terminal seal ring is shown in shown in Fig. 1 and Fig. 2, and terminal seal ring is cylindrical structure, and its cylindrical is contained on engine framework, and motor terminal electrode terminal is interspersed on seal ring two slot holes; Motor of engine is essential by terminal delivered current, after energising, just runs well.Current domestic similar products, use be General Purpose Rubber material, insulating property are bad, in using process, easily lose efficacy, and cause motor bad connection.Secondly, be illustrated in figure 1 existing terminal ring structure, external cylindrical surface is for facing directly, and assembling effect is bad, easily comes off in actual use; And sealability is also bad, after use a period of time, there is certain interval, dust is easy to enter, thereby affects the working life of part.In addition as shown in Figure 2, existing terminal seal ring, what neutral position adopted conventionally is circle slot hole structure, and this circle slot hole structure locating effect is bad, and metal terminal is easily subjected to displacement, thereby affects the stable of electric conductivity.

Model utility content

The deficiency that the utility model exists for prior art just, provides a kind of motor terminal seal ring.

For addressing the above problem, technical solution adopted in the utility model is as follows:

Motor terminal seal ring, described seal ring is cylindrical, on its circumference, sealing surface is set, and sealing surface both sides arrange boss, and what the end face of boss was level faces directly.

As the improvement of technique scheme, between described boss and sealing surface, the angle of transition is 135 °.

As the improvement of technique scheme, described seal ring central position arranges the slot of two rectangular cross-sections.

Compared with prior art, implementation result of the present utility model is as follows for the utility model:

Motor terminal seal ring described in the utility model, by boss being set and facing directly, improves the sealability of seal ring, and is convenient to assembling; By the slot of rectangular cross-section is set, effectively prevent coming off of terminal electrode terminal.Seal ring is used by reality, and implementation result is remarkable.

Accompanying drawing explanation

Fig. 1 is motor terminal seal ring plan view in prior art;

Fig. 2 is the left view in Fig. 1;

Fig. 3 is motor terminal seal ring plan view described in the utility model;

Fig. 4 is the left view in Fig. 3.

Embodiment

Content of the present utility model is described below in conjunction with specific embodiments.

As shown in Figure 1, be motor terminal seal ring plan view in prior art, Fig. 2 is the left view in Fig. 1.As shown in Figure 3, be motor terminal seal ring plan view described in the utility model, Fig. 4 is the left view in Fig. 3.

In Fig. 3 and Fig. 4, seal ring 10 described in the utility model is cylindrical, and sealing surface 14 is set on its circumference, and sealing surface 14 both sides arrange boss 11, and what the end face of boss 11 was level faces 12 directly.Between boss 11 and sealing surface 14, have the angle β of transition, angle β is 135 °.Boss 11 is in order to strengthen the sealing of seal ring 10, utilizes like this to face 12 directly and directly contact with motor with sealing surface 14, coordinates tightr.End face 12 directly, not only strengthened sealability, and be convenient to assembling.

Seal ring 10 described in the utility model, arranges two slots 13 in central position, slot 13 is rectangular cross-section, the terminal electrode terminal of the interior insertion motor of slot 13.The slot 13 of rectangular cross-section can effectively prevent coming off of terminal electrode terminal.

Seal ring 10 described in the utility model, adopts the Ethylene Propylene Terpolymer glue material of good insulation preformance to make, and has avoided the leaky of using process, effectively evades motor and loses efficacy and other potential safety hazard.
