Abstract
The utility model discloses a locking ejector half electromagnetic relay's quiet terminal structure, including the conductive metal piece, the lower terminal surface of conductive metal piece is equipped with integrated into one piece's terminal pin, the preceding terminal surface of terminal pin is equipped with a plurality of interval distribution's blind gluey hole from last between, the preceding terminal surface and the rear end face symmetry of conductive metal piece are equipped with the location strip, half conical column of location strip for diminishing gradually downwards from conductive metal piece up end, be equipped with the toper filler opening on the conductive metal piece that two were fixed a position between the strip, the intussuseption of toper filler opening is filled with the inflation filler, evenly set up the through -hole that a plurality of and toper filler opening are linked together on the strip outer wall of location. The utility model discloses structural design is novel, through the rational design of the back -off on the terminal pin, blind gluey hole, location strip, inflation filler isotructure for fastness and stability get a promotion after whole quiet terminal and the base installation, have prolonged life.
Description
Technical field
The utility model relates to electromagnetic relay field, particularly relates to a kind of static terminal structure of locking ejector half electromagnetic relay.
Background technology
Existing market the static terminal of electromagnetic relay relative with the structural strength between pedestal on the weak side, in the long-time course of normal operation of relay, static terminal can because movable contact spring and static contact spring piece reciprocating collision, bond strength between static contact spring piece and pedestal is reduced, cause static terminal to loosen from pedestal, even come off.
Utility model content
The purpose of this utility model is to provide a kind of static terminal structure of locking ejector half electromagnetic relay, and the stability after its installation and anti-loosening performance are obviously promoted, and extend useful life.
The technical solution of the utility model is as follows:
The static terminal structure of locking ejector half electromagnetic relay, it is characterized in that: comprise conductive metal sheet, the lower surface of conductive metal sheet is provided with integrated terminal pins, the front end face of terminal pins is provided with several blind glue holes spaced apart between upper, front end face and the rear end face of conductive metal sheet are arranged with positioning strip, positioning strip is the half-cone post diminished gradually downwards from conductive metal sheet upper surface, conductive metal sheet between two positioning strips is provided with taper filler opening, intumescent filler thing is filled with in taper filler opening, positioning strip outer wall evenly offers several through holes be connected with taper filler opening, the conductive metal sheet of the side of described positioning strip is also provided with contact holes
The static terminal structure of described locking ejector half electromagnetic relay, is characterized in that: the front-rear side walls that described terminal pins is relative is arranged with back-off, and back-off is near the afterbody of terminal pins.
The static terminal structure of described locking ejector half electromagnetic relay, is characterized in that: the position of described taper filler opening is corresponding with positioning strip, and the degree of depth is not less than positioning strip length.
Advantage of the present utility model:
The utility model novel in structural design, by the back-off in terminal pins, blind glue hole, positioning strip, the isostructural appropriate design of intumescent filler thing, after making overall static terminal and pedestal installation, fastness and stability get a promotion, and extend useful life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
See Fig. 1:
The static terminal structure of locking ejector half electromagnetic relay, comprise conductive metal sheet 1, the lower surface of conductive metal sheet 1 is provided with integrated terminal pins 2, the front end face of terminal pins 2 is provided with several blind glue holes 3 spaced apart between upper, can prior drop part glue in a pre-installation, raising intercalation is arranged on compactness and the fastness of the contact after pedestal, the front end face of conductive metal sheet 1 and rear end face are arranged with positioning strip 4, positioning strip 4 is the half-cone post diminished gradually downwards from conductive metal sheet upper surface, conductive metal sheet 1 between two positioning strips 4 is provided with taper filler opening 5, intumescent filler thing 6 is filled with in taper filler opening 5, positioning strip 4 outer wall evenly offers the through hole 7 that several are connected with taper filler opening, intumescent filler thing 6 can part be escaped out after expanded by heating from through hole 7, compactness between pedestal is improved, the conductive metal sheet of the side of positioning strip 4 is also provided with contact holes 8.
The front-rear side walls that terminal pins 2 is relative is arranged with back-off 9, and back-off, near the afterbody of terminal pins, can effectively prevent from coming off after installation.
The position of taper filler opening 5 is corresponding with positioning strip 3, and the degree of depth is not less than positioning strip 3 length.
