Abstract

The utility model discloses a connection structure of a lamp holder and a contact element base. The connection structure mainly comprises the lamp holder, a contact base, a contact cover and a contact pin, wherein the contact element is formed by the contact base, the contact cover and the contact pin. The connection structure is characterized in that four lock hooks stretch out on the upper plane of the contact base; the outer side edge and the two adjacent edges of the top surface of each lock hook are provided with chamfers; the distance between the outer ends of the two lock hooks at the opposite edges is more than the distance between the opposite edges of the inner cavity of the lamp holder; and four shallow slots are arranged at the corresponding positions of the periphery of the inner wall of the lamp holder. The lamp holder is connected with the contact base in a way that the four lock hooks stretching out on the contact base are hooked with the four slots at the periphery of the inner wall of the lamp holder, namely, the two parts are fixedly connected with each other and can not be easy to disconnect. The utility model has the advantages that the connection structure of the lamp holder and the contact element base is simple; no connection trace exists on the surface; the appearance is beautiful; the connection structure can be assembled and disassembled conveniently; and the manufacturing, maintenance and element replacement are very convenient.

Description

The syndeton of a kind of lamp socket and contact base member

Technical field

This paper relates to the syndeton of a kind of display part with the push-button switch signal lamp, particularly a kind of lamp socket and contact base member.

Background technology

Band push-button switch signal lamp is to be used for all kinds of needs light signal and problem prompting function are provided, and the product of circuit function operation can be provided simultaneously.We have the mint-mark character at it, and shift knob and for parts such as light source provide the lamp socket of installing space effect and is equipped with electric contact piece and supporting member, has for igniting light source and carries the connected mode of the contact base member of required electric energy effect.At present the lamp socket of this kind signal lamp display part is connected with the contact base parts mostly that employing glue coheres connection or screw is fixedly coupled mode, the former produces mounting or dismounting inconvenience and can occur cohering inefficacy service time after the length and causes two isolation of components, then there is the structure relative complex in the connection that is screwed, the not attractive in appearance and defective such as mounting or dismounting inconvenience etc. of profile.

Summary of the invention

The purpose of this utility model is to solve existing the problems referred to above of band push-button switch signal lamp in the prior art, and the syndeton of a kind of lamp socket and contact base member is provided.

To achieve these goals, the technical solution of the utility model is: the syndeton of a kind of lamp socket and contact base member, mainly include lampholder part and form the contact base member contact base, contact lid, contact pin, it is characterized in that: stretch out 4 lock hooks on the last plane of contact base, all there is chamfering on the outer side edges of every lock hook end face and adjacent both sides, apart from the opposite side size of size greater than the lamp socket inner chamber, the correspondence position in 4 weeks of lamp socket part inwall has 4 shallow slots between the outer end of opposite side two lock hooks.

Lamp socket is to utilize 4 lock hooks that stretch out on the contact base to catch on inboard wall of lamp holder four grooves all around with being connected of contact base parts, can make two parts fixedly connected, is difficult for throwing off.The advantage of this utility model is; Make the bindiny mechanism of lamp socket and contact base two parts simple, the surface does not have the vestige of connection, good looking appearance, and it is convenient to install and remove, and gives and makes, and maintenance and replacing parts have brought convenience.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing and example the utility model is elaborated.

Mainly include lamp socket 101 among the figure and form contact base member 300 contact base 109, contact cover 106, contact pin 104, screening dust hood 107, rubber blanket 108 and lock parts such as guiding principle silk 105.It is characterized in that; Stretch out 4 lock hooks 102 on the last plane of contact base 109 parts, all there is chamfering on the outer side edges and the adjacent both sides of every lock hook 102 end faces, the outer end of opposite side two lock hooks is apart from the opposite side size of size greater than the lamp socket inner chamber, and the correspondence position in 4 weeks of lamp socket part inwall has 4 shallow slots 103.The material of lamp socket 101 and contact base 109 parts adopts promptly sufficient intensity, has certain flexible engineering plastics injection molded again.

In the assembling, utilize the chamfering of stretching out 4 lock hook end faces outsides on the strain of lamp socket 101 and 109 two kinds of part materials of contact base and contact base 109 parts on the plane, make the inner chamber that can be pressed into lamp socket 101 greater than 2 pairs of lock hooks 102 on the contact base 109 of lamp socket 101 inner chamber opposite side sizes, and catch on 4 shallow slots 103 of correspondence of inner chamber, contact base member 300 is radially fixed.Be provided with dust cover 107 and rubber blanket 108 between lamp socket 101 and the contact base 109, form caulking groove 111 between the last plane of contact base 109 and lock hook 102 lower planes, lamp socket 101 inwall oral areas are provided with boss 110, behind contacted rubber blanket 108 compressive deformations of lamp socket 101 oral area end faces, boss 110, dust cover 107 and the rubber blanket 108 of inboard wall of lamp holder oral area can be embedded on the contact base in 109 the caulking groove 111, contact base member 300 is axially fixed.

Only needing during dismounting that finger is inserted on contact base 109 parts one has in the groove of groove side and firmly breaks off with the fingers and thumb, two parts can be taken apart.
