Abstract
The utility model discloses a relay housing structure capable of limiting a movable spring assembly. A place, which is inside the relay housing structure and opposite to the movable spring assembly, is provided with one or two limit ribs. The limit ribs enable the movable spring assembly of a relay to obtain a support force provided by the housing when the movable spring assembly is deformed caused by mechanical shock, thereby preventing plastic deformation of the movable spring assembly and ensuring that the relay does not become invalid when an automobile withstands the mechanical shock.
Description
Technical field
The utility model relates to a kind of electromagnetic relay, espespecially a kind of relay1 case structure that can be spacing to movable spring assembly.
Background technology
Electromagnetic relay is a kind of electronic control device, is comprised of coil, yoke, armature, movable contact spring, sound contact, pedestal and shell etc., and its operating circuit principle is to complete large electric current (high power) break-make by low current (small-power) control signal.
Except shell, generally as shown in Figure 2, it comprises pedestal 1, is arranged on yoke 2, movable spring assembly 3 and coil block 4 on pedestal 1 internal structure of relay.This movable spring assembly 3 is by armature 32 with movable contact spring 31 riveted joints and be integral, and this movable contact spring 31 is provided with moving contact 33 and, and to be fixed therein the fixed contact 34 on lead-out terminal 5 relative.Described coil block 4 is positioned at a side of movable spring assembly 3, coordinates shown in Figure 3ly, and it comprises bobbin 41, coil 42, two signal input control terminals 43 and unshakable in one's determination 44, formation control inputs loop after this coil 42 is connected with two signal input control terminals 43.This relay also is provided with three lead-out terminals 5 in addition.
The operating principle of this relay is: after the input control signal of described control inputs loop, coil 42 produces magnetic field by electric current, under magnetic fields, makes movable spring assembly 3 to 44 direction motions unshakable in one's determination, makes fixed contact 34 and moving contact 33 adhesives.After the control signal of control inputs loop input was cancelled, movable spring assembly 3 was because the restoring force of movable contact spring 31 turns back to original position.
Yet, when movable spring assembly 3 turns back in the process of origin-location, if there is the overbump situation to produce, movable spring assembly 3 can be because crossing momentum effect so, exceed original position, cause movable spring assembly 3 distortion, after control inputs signal next time, movable spring assembly 3 can not complete normal action, causes product failure or quality to descend.
But; the relay1 case internal structure of existing design is very simple; its inner movable spring assembly position relatively is a simple planar structure; when automobile overbump (suddenly stopping the states such as anxious startup), shell does not have one to movable spring assembly and supports or protective effect like this; just may cause the distortion of movable spring assembly in the relay internal structure; and after the movable spring assembly distortion, relay can't be realized basic on-off function again, or reduce its life-span or quality.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of relay1 case structure that can be spacing to movable spring assembly, it is intended to not adopt the parameter that changes electromagnetic relay, and comprise under structure situation such as not changing armature, coil, yoke, movable contact spring, contact, pedestal, by simple shell mechanism change, reach and prevent that overbump from causing the new construction design of movable spring assembly distortion.
For solving the problems of the technologies described above, technical solution of the present utility model is:
A kind of relay1 case structure that can be spacing to movable spring assembly, this enclosure place corresponding with the movable contact spring of described movable spring assembly is provided with limit ribs.
Described limit ribs is provided with parallel two.
After adopting such scheme, due to the utility model, increased outstanding rib in the enclosure of the relay place corresponding with the movable contact spring of relay movable spring assembly, when the relay movable spring assembly is out of shape because of mechanical shock, the support force provided by shell is provided, thereby can stop the plastic deformation of relay movable spring assembly, guarantee that relay can not lose efficacy during because of mechanical shock at automobile.
The accompanying drawing explanation
Fig. 1 is the structural representation of relay1 case described in the utility model;
Fig. 2 is the inside basic structure schematic diagram of relay except shell;
Fig. 3 is the structural representation of relay coil assembly;
Fig. 4 is relay1 case described in the utility model and internal structure assembling schematic diagram.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
What the utility model disclosed is a kind of relay1 case structure that can be spacing to movable spring assembly, as shown in Fig. 1,4, coordinates simultaneously Fig. 2,3.Described relay is identical with existing relay, comprises equally pedestal 1, yoke 2, movable spring assembly 3 and coil block 4, also is provided with three lead-out terminals 5, comprises simultaneously the shell 6 of protecting said structure and reaching functions such as preventing.Except described shell 6, said structure is all identical with existing structure.
Key of the present utility model is: be provided with limit ribs 61 in the inner place corresponding with the movable contact spring 31 of described movable spring assembly 3 of described shell 6, in order to increase spacing area, can reduce the use of material again, this limit ribs 61 can arrange parallel two or three.
Setting due to described limit ribs 61, extreme position that can spacing described movable spring assembly 3, working as like this this movable spring assembly 3 turns back in the process of origin-location, while having the overbump situation to produce and when movable spring assembly is deformed, this movable spring assembly 3, due to the position-limiting action of limit ribs 61, can obtain a support force provided by shell, can not exceed because backwashing origin-location, thereby can prevent the plastic deformation of movable spring assembly, guarantee that relay can not lose efficacy when the mechanical shock because of automobile.
The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, thus variation or the modification in every case according to claim of the present utility model and specification, done, within all should belonging to the scope that the utility model patent contains.
Claims (2)
- One kind can be spacing to movable spring assembly the relay1 case structure, it is characterized in that: this enclosure place corresponding with the movable contact spring of described movable spring assembly is provided with limit ribs.
- 2. a kind of relay1 case structure that can be spacing to movable spring assembly according to claim 1, it is characterized in that: described limit ribs is provided with parallel two.
