Description
Technical field
The utility model relates to contactor technical field, refers in particular to a kind of contactor and reduces friction buffer structure.
Background technology
In prior art, contactor generally includes the body, fixed contact, contact support and moving contact; Fixed contact is arranged on the body, and moving contact is arranged in contact support, and contact support activities is arranged in the body, at the move under influence of electromagnet, makes moving contact contact with fixed contact or separate; For installing armature, usually in contact support, establishing pin-and-hole, being provided with pin-and-hole accordingly at armature, then, inserting in two pin-and-holes successively by steady pin, armature is arranged on contact and supports, its defect is:
One, armature release time, contact resets under being supported in the effect of reaction spring, and contact support and the body are collided, and due to contact support comparatively fragile, contact support is easily damaged.
Two, when contact is supported in electromagnet move under influence, contact supports that side and the body rub, and this friction is the friction of face, face, makes the wearing and tearing of contact support and the body larger.
Three, for preventing steady pin from coming off, often need to design comparatively complicated fixed structure, steady pin is spacing, complex structure and increase cost.
Utility model content
The purpose of this utility model is to provide a kind of contactor to reduce friction buffer structure, to cushion the collision between contact support and the body, reduces the friction between contact support and the body.
For reaching above-mentioned purpose, solution of the present utility model is:
A kind of contactor reduces friction buffer structure, comprises contact support, the impingement area that contact support contacts with the body installs bolster, described bolster is formed elastic buffer face.
Further, described contact support installs armature by steady pin; Described bolster forms by cushioning main body and cushioning the radial capping extended to form of main body; Buffering main body is arranged on the impingement area that contact support contacts with the body, and elastic buffer face is formed in be cushioned in main body, and capping is resisted against steady pin end.
Further, described capping forms containing cavity, steady pin end be placed in containing cavity and with capping against.
Further, the contact of described capping and the body is the localized contact of point cantact, linear contact lay and face contact form.
Further, described buffering main body arranges the first grab, and contact support is arranged the first draw-in groove, bolster is installed contact support by being coordinated of the first grab and the first draw-in groove.
Further, described contact support is arranged buffering main body mounting groove, mounting groove at least one end forms block, and buffering main body at least forms the breach mated with block in one end, buffering main body is arranged in mounting groove, and block is stuck in breach and limits the disengaging of bolster horizontal direction.
Further, described contact support arranges the second draw-in groove, capping is arranged the second grab, bolster is arranged on contact and supports, the second grab snaps in the second draw-in groove and limits the disengaging of bolster vertical direction.
Further, described elastic buffer face is the elastic buffer face of concavo-convex setting.
After adopting such scheme, the impingement area that the utility model contacts with the body in contact support installs bolster, described bolster is formed elastic buffer face, when contact support and the body collide, due to the elastic buffer effect in elastic buffer face, contact is supported stressed less, be not easy damaged, save use cost.
The capping that buffering main body radial direction extends to form, this capping is resisted against steady pin end, thus restriction steady pin is deviate from, and its structure is comparatively simple, saves use cost.
Capping contacts one end with the body and is set to sphere, is point cantact with the body, makes contact support and the body rub less, and then makes contact support and the body wear and tear less.

Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in detail.
Consult shown in Fig. 1 to Fig. 7, a kind of contactor that the utility model discloses reduces friction buffer structure, comprise contact and support 1, the impingement area that contact support 1 contacts with body (not shown) installs bolster 2, described bolster 2 forms elastic buffer face 20, when contact support 1 and the body collide, due to the elastic buffer effect in elastic buffer face 20, contact is supported, and 1 is stressed less, is not easy damaged, saves use cost.
Described contact support 1 installs armature 4 by steady pin 3, is specially and arranges pin-and-hole 11 in contact support 1, as shown in Figure 5, pin-and-hole 41 is provided with accordingly at armature 4, then, inserted successively in two pin-and-holes (11,41) by steady pin 3, armature 4 is arranged on contact and supports on 1.
The capping 22 that described bolster 2 is extended to form by buffering main body 21 and buffering main body 21 radial direction forms.Buffering main body 21 is arranged on contact and supports that, on 1 impingement area contacted with the body, elastic buffer face 20 is formed in buffering main body 21, and capping 22 is resisted against steady pin 3 end, thus restriction steady pin 3 is deviate from, and its structure is comparatively simple, saves use cost.In the present embodiment, described capping 22 forms containing cavity, steady pin 3 end be placed in containing cavity and with capping 22 against.
Described capping 22 and the contact of the body are the localized contact of point cantact, linear contact lay and face contact form.Described capping 22 contacts one end with the body can be set to sphere, be point cantact with the body, as shown in Fig. 4 and Fig. 4 a, also can be set to cylinder, be linear contact lay with the body, as shown in Fig. 5 and Fig. 5 a, also can contact for partial face, as shown in Fig. 6 and Fig. 6 a, make contact support 1 and the body rub less, and then make contact support 1 and the body wear and tear less, save use cost.
In the present embodiment, when installing bolster 2, buffering main body 21 arranges the first grab 211, and contact support 1 is arranged the first draw-in groove 12, bolster 2 is installed contact support on 1 by being coordinated of the first grab 211 and the first draw-in groove 12.
Described contact support 1 is arranged buffering main body 21 mounting groove 13, mounting groove 13 at least one end forms block 131, buffering main body 21 at least forms the breach 212 mated with block 131 in one end, buffering main body 21 is arranged in mounting groove 13, and block 131 is stuck in breach 212 and limits the disengaging of bolster 2 horizontal direction.
Described contact support 1 is arranged the second draw-in groove 14, capping 22 is arranged the second grab 221, bolster 2 is arranged on contact and supports on 1, and the second grab 221 snaps in the second draw-in groove 14 and limits the disengaging of bolster 2 vertical direction.
For strengthening the elastic buffer effect of bolster 2 further, described elastic buffer face 20 is the elastic buffer face of concavo-convex setting, and buffering main body 21 two ends are set to thinner thickness, namely be set to thinner away from capping 22 position, and be set to thicker near capping 22 position, make its elasticity better, and intensity is enough.
The foregoing is only preferred embodiment of the present utility model, not to the restriction of this case design, all equivalent variations done according to the design key of this case, all fall into the protection range of this case.
