Abstract
The utility model discloses a plug pin connector with a boss structure, wherein the plug pin connector with the boss structure comprises a swivel nut, an outer shell, an insulator and a plug pin. The plug pin connector with the boss structure is characterized in that the outer shell is a casing pipe which is provided with a boss hole and a groove; the insulator is a connector assembly seat which is provided with a through hole and bosses at two ends; the plug pin is sleeved in the central through hole and is in interference fit with the insulator; the insulator is sleeved in the outer shell and is in interference fit; the swivel nut is sleeved and clamped on the outer shell through a clamping ring arranged in the groove; and the port of an 'O'-shaped seal ring between the swivel nut and the outer shell is sealed. Compared with the prior art, the plug pin connector with the boss structure provided by the utility model is simple in structure and high in reliability, can increase the wall thickness of the shell at the mutual matched part in the mutual matching and meshing process of the connector, and effectively lowers the product invalidity and mounting and maintain expense caused by shell deformation for the moment is over great in mutual match.
Description
Technical field
The utility model relates to components and parts and electrically connects technical field, especially a kind of contact pin connector of boss structure.
Background technology
In the communications industry, use the radio frequency connector of serial screw-threaded couplings such as SMA and SSMA in a large number at present.Such connector is made up of a pair of contact pin connector of joining mutually and receptacle connector, and matching model generally all adopts the screw-threaded coupling form.Because connector good anti-vibration reliability is high after the screw-threaded coupling, so such connector is widely used.
The radio frequency connector of prior art is the connector of immobile interface size, that is to say that the contact pin connector of joining mutually and the interface dimensions of its cooperation place of receptacle connector provide.Shell interface size like contact pin connector in application process is thinner, exists the potential safety hazard of easy deformation in mutual timing, when assembling connects if the torque spanner that not strict usefulness has certain numerical value goes operation to be easy to cause housing distortion to cause product rejection.
The utility model content
The purpose of the utility model is the contact pin connector of a kind of boss structure of designing to the deficiency of prior art; Adopt the shell of boss structure; Make connector in the engagement process of joining mutually; Can increase the housing wall thickness of joining the place mutually, effectively reduce that mutual timing moment is excessive to be caused product failure that housing distortion causes and scrap, further improve the reliability of connector.
The purpose of the utility model is achieved in that a kind of contact pin connector of boss structure, comprises swivel nut, shell, insulator and contact pin, is characterized in that said shell is the sleeve pipe that port is provided with boss hole, and its shell is provided with annular groove; Said insulator is the connector seat that is provided with central through hole, and its two ends are provided with boss; Contact pin is sleeved in the central through hole and insulator is an interference fit; The insulator suit is interference fit in the enclosure, the boss of one of which end and boss hole clamping, and the boss of the other end is fastened on the contact pin; Be provided with snap ring in the annular groove of shell, swivel nut is sleeved on the shell by snap ring, is provided with the port sealing of " O " shape sealing ring between swivel nut and shell.
Said insulator is the connector seat that elastomeric material is made.
The utility model compared with prior art has simple in structure; Reliability is high; Make connector in the engagement process of joining mutually, increase the housing wall thickness join the place mutually, effectively reduced the excessive expense that causes product failure that housing distortion causes and installation, maintenance of mutual timing moment.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the shell mechanism sketch map;
Fig. 3 insulator structure sketch map.
Embodiment
With specific embodiment, the utility model is done further elaboration below:
The utility model is assembling like this and uses: contact pin 4 is sleeved in the central through hole 31 and is interference fit with insulator 3; Insulator 3 is sleeved on and is interference fit in the shell 2; The boss 32 and boss hole 22 clampings of insulator 3 one ends, the boss 32 of its other end is fastened on the contact pin 4; Swivel nut 1 is sleeved on the shell 2 by the snap ring 5 that is arranged in the annular groove 21, and 2 on swivel nut 1 and shell are provided with the port sealing of " O " shape sealing ring 5.In the engagement process that the utility model and receptacle connector are joined mutually, can increase the housing wall thickness of joining the place mutually, effectively reduce the excessive product failure that causes housing distortion to cause of mutual timing moment.And integral body has formed a radio frequency path on the end face at receptacle connector when the end face of the boss hole 22 of contact pin 4 and shell 2 holds out against, and further improves the reliability of connector.
More than just the utility model being further described, is not in order to the restriction this patent, and all is that the utility model equivalence is implemented, and all should be contained within the claim scope of this patent.
