Abstract
An elastic pin contact in an electric connector comprises an elastic pin and a sleeve at one end of the elastic pin. The elastic pin is integrated with the sleeve. The middle of the elastic pin is a projecting cylinder. A plurality of grooves are made from the head of the elastic pin to the inside, and the head of elastic pin is chamfered. The diameter of the projecting excircle of the middle of the elastic pin is larger than the inner diameter of a hole used with the elastic pin. Preferably, the head of the elastic pin is welded. The elastic pin and the sleeve are integrally processed, so that parts in the pin and the sleeve are integrated, the middle stage of crimping the contact is omitted and size uniformity of parts is increased. The elastic pin can be directly made of a metal wire by equipment such as numerical control lathe. The metal wire of the novel pin is higher in mechanical strength and better in uniformity than a stranded pin of multiple metal wires. The contradiction between high reliability and small size of the contact in the electric connector is overcome.
Description
Technical field
The present invention relates to technical field of electric connectors, be specifically related to a kind of electric connector elastic contact pin contact.
Background technology
Electric connector is generally by shell, insulator, and contact three parts form, 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 littlely 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 and jack form Multi-contact, and many elasticity copper cash consist of parallel systems, 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 one side twisted wire contact pin more complicated cost in production and processing is higher, the twisted wire contact pin is to form with sprung copper skein silk system, and the similar Compress Spring of its structure so its rigidity is not high, the shortening phenomenon occurs 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 crimping are comprised of two parts like this, make the parts after the contact crimping exist axiality poor, the problem such as axial dimension is long, and the crimping point reliability is poor.
Project team of the present invention is on the internet with regard to this theme, and at home and abroad patent documentation and the journal article retrieval of publishing, not yet find report or the document closely related and the same with the present invention.
Summary of the invention
For solving above-mentioned problems of the prior art, order of the present invention is to provide a kind of electric connector elastic contact pin contact, the problem such as overcome poor rigidity, easily shortening that existing resilient strand contact pin contacting piece exists, axiality is poor, axial dimension is long and dimensional uniformity is poor; 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 elastic contact pin contact, 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 in conjunction with.
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.
Compared to the prior art the present invention has following advantage:
1, novel structure of the present invention, elastic contact pin and sleeve pipe are processed as a whole, realized that two parts of contact pin and sleeve pipe are integrated, save contact crimping intermediate link, reduce the part length size, eliminated the impact of crimping on parts reliability and axiality.
2, elastic contact pin of the present invention can directly process by equipment such as numerically controlled lathe, milling machines with metal wire rod, easily realizes batch production processing, has improved part productivity ratio, has reduced cost.
3, structural rigidity of the present invention is good, has thoroughly solved the shortening phenomenon that existing electric connector twisted wire contact pin contacting piece exists.
