Abstract
The utility model discloses an elastic trip support with positioning holes, and aims at providing an elastic trip support with the positioning hole, which has simple structure and high positioning accuracy of elastic trips. The elastic trip support comprises a plastic support, and two elastic trips are fixed on the support. The elastic trip support is characterized in that the tail end of each elastic trip is extended with a positioning piece, each positioning piece is provided with a positioning hole, an injection mold can be provided with positioning pins when in injection molding of the support, and the positioning pins are inserted in the positioning holes for injection, thus guaranteeing accurate relative positions of the two elastic trips and the support, and the positioning pieces are removed after molding. The elastic trip support with positioning holes has the advantages of high positioning accuracy, uniform extension dimension of the elastic trips.
Description
Technical field
The utility model relates to receiver, relates in particular to a kind of flexure strip support that has location hole.
Background technology
It includes support common receiver, is fixed with two flexure strips, T iron on the support, is fixed with the ring-type magnet steel on the T iron, the outer ring of T iron is equipped with voice coil loudspeaker voice coil, voice coil loudspeaker voice coil links to each other with vibrating membrane, and the perimeter bond of vibrating membrane is fixed on the support, and two wiring of voice coil loudspeaker voice coil link to each other with two flexure strips respectively.In order to make receiver keep excellent contact and fixing reliable when mounted, requirement two relative supports of flexure strip when the support injection moulding have identical position, are meant that mainly the length of stretching out is identical.Because injected plastic need put into flexure strip earlier when injection moulding after because the injection of plastics makes prepositioned flexure strip be subjected to displacement, and can not guarantee the positional precision of two flexure strips and relative support, influences the accuracy of manufacture and the quality of part.
The utility model content
The purpose of this utility model provides a kind of simple in structure, flexure strip support that has location hole that the flexure strip positioning accuracy is high.
In order to reach above-mentioned requirements, the flexure strip support that has location hole is achieved through the following technical solutions: it includes the support of plastics, be fixed with two flexure strips on the support, it is characterized in that the tail end prolongation of described flexure strip has spacer, on spacer, be shaped on location hole.
Between spacer and flexure strip, be shaped on recessed impression.
The flexure strip support that has location hole according to the such scheme manufacturing, by tail end prolongation spacer is arranged at flexure strip, on spacer, be shaped on location hole, when making, the support injection moulding can on injection mold, be shaped on alignment pin, alignment pin is inserted in injection moulding in the location hole, guarantee the relative positional accuracy of two flexure strips and support, can remove spacer again after the moulding.This structure has the positioning accuracy height, and flexure strip stretches out the unified advantage of size.
Description of drawings
Fig. 1 is the flexure strip support front view that has location hole;
Fig. 2 is the flexure strip front view that has spacer, location hole;
Fig. 3 is the flexure strip support front view that has location hole after the removal spacer.
Wherein: 1, support; 2, flexure strip; 3, spacer; 4, location hole; 5, impression.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation that has the flexure strip support of location hole.It includes the support 1 of plastics as seen from the figure, is fixed with two flexure strips 2 on the support, and the tail end of described flexure strip 2 prolongs spacer 3, is shaped on location hole 4 on spacer 3, is shaped on recessed impression 5 as shown in Figure 2 between spacer 3 and flexure strip 2.Can utilize again after this support 1 moulding that the defective of impression 5 is curved goes after the spacer 3 as shown in Figure 3.
Claims (2)
1. have the flexure strip support of location hole, it includes the support of plastics, is fixed with two flexure strips on the support, it is characterized in that the tail end prolongation of described flexure strip has spacer, is shaped on location hole on spacer.
2. the flexure strip support that has location hole according to claim 1 is characterized in that being shaped on recessed impression between spacer and flexure strip.
