Description

The electric connector combination

The utility model relates to a kind of electric connector combination, refers in particular to a kind of electric connector combination that is used for transmitting radio frequency signal.

The technology relevant with this case can be with reference to United States Patent (USP) the 4th, 580, and shown in No. 862, the pin connector butt end of the electric connector of its announcement combination is provided with first housing of hollow, and a plug terminal is installed with therein.The socket connector butt end of butt joint is provided with second housing, and female terminal is housed in second housing, and the second housing periphery is provided with screw thread.When butt joint, second housing of socket connector is plugged in first housing of pin connector, and plug terminal docks with female terminal simultaneously, and the screw thread of the second housing periphery is sealed to guarantee reliable butt joint the between the two with first inner walls.But, because its plug terminal and female terminal are direct grafting at first, and corresponding guiding device is not set therebetween, therefore, plug and socket connector are in docking operation, if one of them has deviation slightly on aspect the butt joint axis, will cause the terminal of another connector to be bent damage.This situation is even more serious in radio frequency connector, because of the radio frequency connector required precision higher, and size is less relatively, the terminal mechanical strength is lower, if therefore the connector of butt joint dimensionally error or when pegging graft the deviation of relative axis direction bigger, terminal is very easily bent, and when serious terminal is fractureed.

Certainly, industry also proposes corresponding solution, related content can be with reference to United States Patent (USP) the 5th, 611, No. 707, the pin connector that it disclosed externally is provided with an elasticity between the insulating body of housing and fixing terminal and inserts tube, elasticity is inserted the tube front end and is provided with a bulge loop, and the blocking of socket connector shielding casing front end has an insulating sleeve, the insulating sleeve end is provided with an inclined-plane and forms the groove of accommodating bulge loop with the inclined-plane with the shielding casing inwall, insert tube by elasticity during grafting and provide the effect of guiding normotopia in advance to docking of terminal, can make reliably butt joint each other between terminal with insulating sleeve; Simultaneously by bulge loop and groove mutually buckle increase the confining force of butt connector.But because its socket connector need be provided with an insulating sleeve separately, and insulating sleeve need be organized and is located on the shielding casing.Less and guarantee under the situation of degree of precision at accessory size, its manufacturing and assembling are all quite difficult and be unfavorable for reducing cost; In addition, the bulge loop of pin connector is located at elasticity and inserts the tube end, to engage with the groove that is located at the insulating sleeve end.Like this, when pin connector is subjected to active force perpendicular to the grafting axis direction, it may make resilient sleeve produce bigger moment of torsion at bulge loop and engage grooves place, so that produces strain, and then may make the relative female terminal skew of plug terminal so that plug or female terminal bending damage.

The purpose of this utility model is to overcome the prior art defective, and a kind of electric connector combination that two electric connectors are firm, safety is docked that makes is provided.
