Abstract

The utility model relates to a cable connector combination, comprising a first connector and a second connector. Wherein the first connector comprises a first shell, a first insulator, a first terminal and an elastic sleeve; the front end of the first shell is formed with a periphery wall which is provided with a blocking groove; the place from the elastic sleeve to the free end with a certain distance is extruded with a buckling ring. The second connector comprises a second shell, a second insulator and a second terminal; one end of the second shell is extruded with a guiding sleeve which is extruded with a blocking key; the inner wall of the second shell is provided with a buckling groove which is buckled with the buckling ring. The matching between the blocking key and the blocking groove makes the two connectors not rotate relatively after connecting and positioning so as to prevent the resisting resistance from being unstable.

Description

Cable connector combination

Technical field the utility model relates to a kind of cable connector combination, refers in particular to a kind of cable connector combination that is used for transmitting radio frequency signal.

The technology that background technology is relevant with this case 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 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.In addition, itself and general connector have common shortcoming, i.e. the pin connector of assembly is not aimed at socket connector and the design of location, so that is easy to generate rotation at two connectors after connection, cause the resistance value between the connector to change, influence signal transfer quality.

The summary of the invention the purpose of this utility model is to provide a kind of firm butt joint of two electric connectors and reliable cable connector combination of electric property of making.

The purpose of this utility model is achieved through the following technical solutions: the utility model comprises first and second connector, wherein first connector comprises that first housing, first insulator, group are located at the first terminal in first insulator and group and are located at resilient sleeve between first housing and first insulator, the first housing front end forms a peripheral wall, one draw-in groove is arranged on the peripheral wall, and resilient sleeve protrudes at a distance of a distance of its free terminal and is provided with a snap collar; And second connector comprises that second housing, second insulator, group are located at second terminal in second insulator, and second housing, one end protrudes and be provided with the guiding sleeve, protrudes with the corresponding position of the draw-in groove of first connector on the guiding sleeve to be provided with the card key.In addition, second inner walls is provided with the buckle slot that engages with snap collar.

The utility model makes two connectors be easy to mutual aligning when docking by the cooperation of card key and draw-in groove, and be difficult for producing relative rotation connecting the back, location, thereby the impedance after making two connectors connect remains on and prevents in the fixed range that impedance from producing suddenly big or suddenly small phenomenon.
