Abstract

A relay pushing card limiting structure comprises an armature disposed in a casing of a relay, and a shrapnel. The armature and the shrapnel are connected via a pushing card, a top surface of which extends with a limiting protrusion. A front side and a rear side of an inner top surface of the casing corresponding to the limiting protrusion are respectively provided with a front limiting plate and a rear limiting plate. A left side and a right side of the pushing car are also equipped with a baffle block. A middle limiting plate is disposed between the front limiting plate and the rear limiting plate in such a manner to be corresponding to the baffle block. The relay pushing card limiting structure of the utility model is characterized in that the baffle block is arranged at left and right sides of the pushing card, the middle limiting plate is disposed above the casing corresponding to the two baffle blocks, and meanwhile bottoms of the front limiting plate, the rear limiting plate and the middle limiting plate are aligned. During the movement of the pushing card, due to the limiting effect of the middle limiting plate on the pushing card baffle blocks, the failure phenomenon caused by the disability of the pushing card to be back in place does not occur. The arrangement of the middle limiting plate enables to offer protection during the whole movement process of the pushing card. The relay pushing card limiting structure is simple and reasonable and puts an end to the quality problem of the disengagement of the pushing card of the relay, enhancing the product quality and reducing the maintenance cost.

Description

Relay push card position limiting structure

Technical field

The utility model relates to a kind of relay, particularly relay push card position limiting structure.

Background technology

Present a part of power relay, the location of its push card 2 is: an end is fixed in the aperture of shell fragment 4, and the other end is enclosed within the top of armature 3; The push card end face extends spacing preiection 2.1, and the both sides, front and back of the corresponding spacing preiection of shell 1 ' inner top surface are provided with respectively and prevent front limit muscle 1.1 that push card is deviate from and the rear position margining plate 1.2 ' that limits the push card movement travel, as depicted in figs. 1 and 2.This kind design; just at relay position-limiting action of having deviate to push card under static state; but under dynamically; push card will lose protection, the end as push card and armature socket, and (seeing C arrow place among Fig. 3) easily is upturned; make in the rearward end immigration front limit muscle 1.1 ' and the groove position between the rear position margining plate 1.2 ' of push card; blocked by front limit muscle 1.1 ' when causing the push card return, have back phenomenon not in place, as shown in Figure 3 and Figure 4.

The utility model content

The purpose of this utility model aims to provide a kind of simple and reasonable, and the relay push card position limiting structure that push card can not return under the anti-dynamic is to overcome weak point of the prior art.

A kind of relay push card position limiting structure by this purpose design, comprise the armature and the shell fragment that are arranged in the relay1 case, armature is connected by push card with shell fragment, the push card end face extends spacing preiection, the front and back side of the corresponding spacing preiection of shell inner top surface is respectively arranged with front limit plate and rear position margining plate, its architectural feature is that the push card left and right sides also is provided with block, limiting plate in the middle of corresponding block is provided with between the forward and backward limiting plate.

Described front limit plate and rear position margining plate vertically are arranged on the shell inner top surface; Middle limiting plate is provided with two, is horizontally installed between the forward and backward limiting plate, and two blocks top about laying respectively at.

Described front limit plate, rear position margining plate are indulged and the bottom surface of middle limiting plate maintains an equal level.

The top socket of described push card front end and armature, rear end and shell fragment join; Shell fragment is provided with the contact.

The utility model is by being provided with block in the push card left and right sides, and the top of corresponding two blocks of shell be provided with in the middle of limiting plate, simultaneously, the front limit plate, rear position margining plate is vertical and the bottom surface of middle limiting plate maintains an equal level; In the push card course of action, because middle limiting plate is to the position-limiting action of push card block, push card can not take place back not in place and failure phenomenon that cause, and the setting of middle limiting plate can be moved whole process to push card and be played a protective role.It is simple and reasonable, has stopped the quality problems that the relay push card is deviate from, and has promoted product quality and has reduced maintenance cost.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described.

Referring to Fig. 5, Fig. 6, this relay push card position limiting structure comprises the armature 3, push card 2 and the shell fragment 4 that are arranged in the relay1 case 1, the top socket of push card 2 front ends and armature 3, and rear end and shell fragment 4 join; Shell fragment is provided with contact 5.

Push card 2 end faces extend spacing preiection 2.1, and the front and back side of the corresponding spacing preiection of shell 1 inner top surface is vertically arranged with front limit plate 1.1 and rear position margining plate 1.2 respectively.The push card left and right sides also is provided with block 2.2, limiting plate 1.3 in the middle of corresponding two blocks are horizontally arranged with between the forward and backward limiting plate.The bottom surface of front limit plate 1.1, rear position margining plate vertical 1.2 and middle limiting plate 1.3 maintains an equal level.
