Abstract

The utility model discloses a mounting structure for a relay housing. The relay housing is an approximate rectangular housing, and covers a relay assembly. Ribs are respectively arranged at four corners of the inner wall of the relay housing, and a sharp projection is arranged at the lower end surface of each rib. According to the utility model, by the ribs with sharp projections, the housing can be engaged with a base of a base assembly, such that the relay assembly is in gapless fit with the housing, and the vibration noise of the housing is eliminated. The mounting structure provided by the utility model enables the noise generated by the vibration of the housing to be eliminated without additional components and assembly steps. Besides, the mounting of the housing can be automatically completed in an assembly line without additional investment of equipment or personnel and without changing the original mounting method.

Description

The installing mechanism of relay1 case

Technical field

The utility model, about a kind of relay construction, refers to the installing mechanism that a kind of relay1 case coordinates with relay assembly especially.

Background technology

AUTOMOTIVE RELAY is a kind ofly at control end, to drive with very little electric current the device that the break-make that can bear the switch of very large electric current is controlled the break-make of vehicle-mounted load, can reach the effect of control end in the protection automobile.

At present, along with the fast development of automobile industry, automobile in use comfortableness also has increasing requirement, wherein just comprises the noise control of mobile unit.General for certain dust protection waterproof ability is provided to relay, need to a plastic casing be installed to relay.Current producer is on the market just used an easy casing on relay, to complete its dust protection water-proof function.

The shortcoming of this kind shell is to reckon without shell with relay, to coordinate while closely not having space, can, along with the generation noise that jolts of automobile, then affect passenger's comfortableness.

The utility model content

The purpose of this utility model is to provide a kind of installing mechanism of relay machine shell, its can do not increase additional parts condition under, relay is coordinated with the shell gapless, the vibrating noise of shell is eliminated.

For achieving the above object, solution of the present utility model is:

A kind of installing mechanism of relay1 case, this relay1 case are the housing of a nearly rectangle, and its cover is placed on relay assembly, and wherein four corners at the relay1 case inwall are respectively equipped with rib, and are formed with sharp salient angle on the lower surface of each rib.

Described each rib is that the below to relay1 case arranges from the top of relay1 case.

After adopting such scheme, the utility model is by arranging the rib with sharp salient angle in four corners of section in the enclosure, can with the base of base assembly between realize setting coordinating, make relay assembly and shell realize that gapless coordinates, the vibrating noise of shell is eliminated.Structural design of the present utility model, can, under the condition that does not increase additional parts and assembly process, eliminate the noise that the shell vibrations produce; And do not need extra equipment and personnel to drop into, do not need to change original mounting means yet, can on streamline, automatically complete the installation of shell.

Embodiment

Below in conjunction with accompanying drawing, explain execution mode of the present utility model:

As shown in Fig. 1 to Fig. 3 A, the utility model has disclosed a kind of installing mechanism of relay1 case, this relay1 case 1 is the housing of a nearly rectangle, its cover is placed on relay assembly, its key is: four corners at relay1 case 1 inwall are respectively equipped with rib 11, this rib 11 is that the below to relay1 case 1 arranges from the top of relay1 case 1, and on the lower surface of each rib 11, is formed with sharp salient angle 12.Shell 1 adopts engineering plastics, make it have certain intensity, and shape can be very complicated, meets matching requirements.In relay assembly directly with the base 40 employing engineering plastics of housing contacts, make it have certain intensity and complicated shape.

Coordinate shown in 4, when relay1 case of the present utility model was implemented on relay, the critical piece of this relay comprised shell 1, movable spring assembly 2, iron core 3, base assembly 4, coil block 5 and yoke 6.At first the base assembly 4 of coil block 5 being packed into from top to bottom, secondly the base assembly 4 of yoke 6 being packed into from top to bottom, just iron core 3 inserts coil block 5 from left to right subsequently, then the base assembly 4 of movable spring assembly 2 being packed into from top to bottom, finally be inserted in shell 1 from top to bottom, the relay finished product has assembled.

Because four corners in shell 1 inside increase respectively rib 11, and on rib 11, grow the sharp salient angle 12 that intensity is not high, sharp salient angle 12 on rib 11 can be flattened by relay base 40 after shell 1 is seated, thereby shell 1 and relay assembly are closely cooperated.And in the useful life of shell 1, the sharp salient angle 12 of flattening can provide certain elastic force, make shell 1 and closely cooperating of relay assembly obtain dual assurance.

As can be seen here, the utility model is by arranging the rib 11 with sharp salient angle 12 in four corners of shell 1 inside, can with the base 40 of base assembly 4 between realize setting coordinating, make relay assembly and shell 1 realize that gapless coordinates, the vibrating noise of shell 1 is eliminated.Structural design of the present utility model, can, under the condition that does not increase additional parts and assembly process, eliminate the noise that the shell vibrations produce; And do not need extra equipment and personnel to drop into, do not need to change original mounting means yet, can on streamline, automatically complete the installation of shell.

These are only preferred embodiment of the present utility model, be not limited to the utility model.In the above-described embodiments, the utility model can have various modifications and variations.Within the method and principle of all modularized designs in the utility model, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.

Claims
