Abstract
A novel elastic pin contact of an electric connector comprises an elastic pin and a sleeve pipe positioned on one end of the elastic pin. The elastic pin and the sleeve pipe are combined into a whole structure. The elastic pin is cylindrical and the middle of the elastic pin is a protrusion. A plurality of grooves is arranged from the head of the elastic pin to the inside of the elastic pin, and the head of each groove is a chamfer. The diameter of an excircle of the protrusion in the middle of the elastic pin is greater than the internal diameter of a pin hole that matches the elastic pin. Preferably, the head of the elastic pin is welded and processed. The elastic pin and the sleeve pipe are machined as a whole, so that components of the pin and the sleeve pipe are integrated, a compression joint central step for the contact is saved and consistency of sizes of the components is improved. The elastic pin can be machined directly by a metal wire rod through a numerical control lathe and other devices, so that the metal wire rod of the novel pin exhibits higher mechanical strength and good consistency compared with multiple metal wires of a twisted wire pin. Moreover, a contradiction between high reliability and small size of the contact of the electric connector is solved.
Description
Technical field
The utility model relates to technical field of electric connectors, is specifically related to a kind of electric connector novel elastic contact pin contacting piece.
Background technology
Electric connector generally is by shell, insulator, and contact three parts are formed, and resilient contact is the vital part of electric connector, it directly affects the reliability of electric connector.At present, the resilient contact of elastic contact pin electric connector adopts the twisted wire contact pin usually.
Phase at the end of the sixties in last century, Fei Lipu has invented the twisted wire contact pin by moral descendants American scientist Deere, its size can do very for a short time and also reliability still very high, preferably resolve this contradiction of connector miniaturization and high reliability, lay a good foundation also for connector to the miniaturization development.
The twisted wire contact pin is by many copper cash Internal and external cycle reverse strandings, and two ends melting welding forms, the protruding bulge in contact pin middle part, bulge part circumcircle diameter is greater than the jack internal diameter, during work because of stressed generation compression.Many elasticity copper cash of outer ring form multiple spot with jack and contact, and many elasticity copper cash constitute parallel system, so its inherent reliability is very high.
Although the resilient strand contact pin contacting piece has satisfied the demand of state's female connector to miniaturization substantially, along with the raising of instructions for use, the twisted wire contact pin also manifests some defectives.Because twisted wire contact pin more complicated cost in production and processing is higher on the one hand, the twisted wire contact pin is to form with sprung copper skein silk system, and the similar compression spring of its structure so its rigidity is not high, the shortening phenomenon takes place easily.On the other hand, twisted wire contact pin overall dimension is difficult to control in art production process, so the part consistency is relatively poor, and the twisted wire contact pin contacting piece needs to carry out crimping with sleeve pipe in using connector, parts after the crimping are made up of two parts like this, make the parts after the contact crimping exist axiality poor, axial dimension is long, problems such as crimping point reliability difference.
The utility model project team is on the internet with regard to this theme, and at home and abroad patent documentation and the journal article retrieval of publishing are found report or the document closely related and the same with the utility model as yet.
The utility model content
For solving above-mentioned problems of the prior art, order of the present invention is to provide a kind of electric connector novel elastic contact pin contacting piece, has overcome poor rigidity, easily shortening that existing resilient strand contact pin contacting piece exists, axiality is poor, axial dimension is long and problem such as dimensional uniformity difference; Preferably resolve the contradiction of electric connector contact high reliability and miniaturization.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of electric connector novel elastic contact pin contacting piece, comprise elastic contact pin 1 and the sleeve pipe 2 that is positioned at elastic contact pin 1 one ends, described elastic contact pin 1 and sleeve pipe 2 are integrated, described elastic contact pin 1 is the column of mid portion projection, and have a plurality of grooves 3 to inside from the head of elastic contact pin 1, and the head chamfering, the circumcircle diameter of described elastic contact pin mid portion projection greater than with its jack internal diameter that is used.
The head of described elastic contact pin 1 has carried out soldering.
The number of described a plurality of groove 3 is 4,6 or 8.
The material of described elastic contact pin 1 and sleeve pipe 2 is elastic copper alloy.
Described elastic copper alloy is beryllium-bronze.
The utility model is compared with prior art, has following advantage:
1, the utility model novel structure, elastic contact pin and sleeve pipe are processed as a whole, realized that contact pin and two parts of sleeve pipe are integrated, save contact crimping intermediate link, reduce the part length size, eliminated the influence of crimping to parts reliability and axiality.
2, the utility model elastic contact pin can directly process by equipment such as numerically controlled lathe, milling machines with metal wire rod, realizes easily producing processing in batches, has improved part productivity ratio, has reduced cost.
3, the utility model structural rigidity is good, has thoroughly solved the shortening phenomenon that existing electric connector twisted wire contact pin contacting piece exists.
