Abstract
A switching contact piece of a miniature electric connector comprises a contact pin contact piece and a jack contact piece, wherein the contact pin contact piece consists of a needle head, a switching needle body and a pin; the jack contact element consists of a switching jack and a pin which are connected in a compression joint mode, and the switching jack and the switching pin body are directly made of pipe section materials with corresponding sizes. The utility model discloses directly adopt the tubular section bar of corresponding internal and external diameter to make switching needle body and switching jack, simplify contact production technology, improve production efficiency. The micro-electric connector is suitable for the micro-electric connector with the contact pitch not greater than 0.635 mm.
Description
One, technical field
The utility model relates to a kind of electric connector contact, relates in particular to a kind of miniature electric connector switching formula contact.
Two, background technology
Along with the develop rapidly of electronic technology, the connector product more and more trends towards miniaturization, microminiaturization.This just makes that small-sized, miniature electric connector processing, production are more and more difficult, the especially processing of contact, the suitable difficulty of production.For the contact center distance is the highly reliable miniature printed board electric connector contact of 0.635mm, and conventional manufacture method is: the printed board contact pin contacting piece is formed by syringe needle and needle body crimping, and jack contact then is an integral structure.Because the printed board micro connector contact jack and the needle body external diameter of 0.635mm spacing are little, diameter of bore is also little, and endoporus depth dimensions big (the dark at least 2.5mm of Socket bore), to making mechanical processing difficulty big, not only working (machining) efficiency is low, and passing rate of processing is not high.
Three, summary of the invention
The purpose of this utility model provides a kind of miniature electric connector switching formula contact piece structure, solves the processing problems of micro connector product contact.
Miniature electric connector switching formula contact described in the utility model comprises contact pin contacting piece, jack contact, and wherein contact pin contacting piece is made up of syringe needle, switching needle body, pin, syringe needle and the one end crimping of switching needle body, other end crimping pin; Jack contact is made up of transfer jack and pin, transfer jack and pin crimping, and spot welding is fixed then.
Described switching needle body and transfer jack directly adopt the pipe profile of corresponding interior external diameter
The utility model miniature electric connector switching formula contact has following advantage:
1, switching needle body and the transfer jack owing to contact can adopt pipe profile processing to get, and need not process endoporus and cylindrical, only cut off with a port part chamfering getting final product, so working (machining) efficiency significantly improves.
2, pin is the part of processing separately, can design different size and structure according to the welding tail end of printed board demand, and transfer jack and switching needle body need not change, and the part universality of contact significantly strengthens.
Four, description of drawings
Fig. 1 is the contact pin contacting piece master cutaway view of the utility model miniature electric connector switching formula contact;
Fig. 2 is the jack contact master cutaway view of the utility model miniature electric connector switching formula contact.
Among the figure: 1-contact pin contacting piece, 2-syringe needle, 3-jack contact, 4-switching needle body, 5-pin, 6-transfer jack.
Five, embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Switching formula contact pin contacting piece described in the utility model comprises contact pin contacting piece 1, jack contact 3, wherein contact pin contacting piece is made up of syringe needle 2, switching needle body 4, pin 5, syringe needle 2 carries out crimping with switching needle body 4 earlier, and then crimping pin 5, for the contact reliability that guarantees switching needle body 4 and pin 5 crimping junctions with obtain than the low pressure connecting resistance, carry out spot welding at switching needle body 4 with pin 5 crimping place, make the crimping position have metal molten mutually, thereby realize reliable the connection; Jack contact is made up of transfer jack 6 and pin 5, and transfer jack 6 and pin 5 crimping spot welding are then fixed,
The transfer jack 6 of the switching needle body 4 of switching formula contact pin contacting piece and switching formula jack contact all adopts through-hole structure, directly adopt corresponding tubing to cut off machine-shaping, the endoporus of switching needle body 4 and transfer jack 6 is consistent with special tubing with external diameter, add and to process endoporus and cylindrical man-hour, only cut off with a port part chamfering getting final product.The utility model is applicable to that the contact spacing is not more than the miniature electric connector of 0.635mm.
