The utility model comprises a square shield shell 1 and a radio frequency connector 2. the utility model is characterized in that: the end of the inner conductor 3 is provided with weld line groove 5; the side of the shell 1 is welded with conductor sheath 4 whose outside is provided with a press sheath 8; the cavity 9 goes through the rear head face of the shell 1, the through hole is provided with an insulating body 6 and a shield cover 7 both of which are arranged at the rear head face of the shell 1. The inner conductor 3 of the radio contact element can be connected with the conductor directly, which meets the requirement of directly connect the radio frequency contact element and the inner conductor 3.

Description

A kind of connector body radio frequency contact

Technical field

The utility model relates to the improvement of connector body with the radio frequency contact.

Background technology

Referring to Fig. 1, it is made up of the radio-frequency joint 2 that a square screening can 1, front end with square screening can 1 are connected to integral body with the structure of radio frequency contact for existing connector body.Radio-frequency joint 2 can be jack structure, also can be the contact pin structure.A cavity 9 coaxial with radio-frequency joint 2 is arranged in square screening can 1 inside, and the inner wire 3 of radio-frequency joint 2 puts in the cavity 9 of shell 1 inside.Porose on the rear end face of square screening can 1 or side, the inner wire 3 of radio-frequency joint 2 directly stretches out from the hole of the rear end face of square screening can 1, perhaps bend after 90 ° from square screening can 1 side the hole stretch out.Its shortcoming is: 3 of the inner wires of this structure are suitable for being connected with printed board, are not suitable for being connected with lead.For the occasion that needs directly are connected with lead, the radio frequency contact of existing structure can not meet the demands.

Summary of the invention

The purpose of this utility model is: propose the radio frequency contact that a kind of energy directly is connected with lead, the inner wire 3 of radio frequency contact directly is connected the needs of occasion with lead to satisfy the demand.

The technical solution of the utility model is: a kind of connector body radio frequency contact, it comprises that a square screening can 1, the front end with square screening can 1 are connected to whole radio-frequency joint 2, a cavity 9 coaxial with radio-frequency joint 2 is arranged in square screening can 1 inside, the inner wire 3 of radio-frequency joint 2 puts in the cavity 9 of shell 1 inside, it is characterized in that the bonding wire groove 5 of an indent is arranged in the termination of inner wire 3; On a side of shell 1, a circular hole 10 is arranged, the center of this circular hole 10 is corresponding with the tip position of inner wire 3, have in the outside of circular hole 10 one with the side welding of shell 1, coaxial lead-in wire sleeve pipe 4 with circular hole 10, there is pressure welding case 8 outside at lead-in wire sleeve pipe 4, the diameter of bore of lead-in wire sleeve pipe 4 and the equal diameters of circular hole 10; The cavity 9 of said shell 1 inside connects the rear end face of shell 1, there is a profile insulator 6 identical to fill in the through hole of shell 1 rear end face with the cross sectional shape of cavity 9, the front end face of insulator 6 is close to the termination of inner wire 3, the rear end face of insulator 6 is deep in shell 1 rear end face, a screening cover 7 that profile is identical with the cross sectional shape of cavity 9 is arranged, and its overall dimension and cavity 9 keep interference fit.

The utility model has the advantages that: the inner wire 3 of radio frequency contact can directly be connected with lead, has satisfied the inner wire 3 direct demands that are connected with lead with the radio frequency contact.

Fig. 2 is a structural representation of the present utility model.

Embodiment

Below the utility model is described in further details.Referring to Fig. 2, radio frequency contact of the present utility model, it comprises that a square screening can 1, the front end with square screening can 1 are connected to whole radio-frequency joint 2, a cavity 9 coaxial with radio-frequency joint 2 is arranged in square screening can 1 inside, the inner wire 3 of radio-frequency joint 2 puts in the cavity 9 of shell 1 inside, it is characterized in that the bonding wire groove 5 of an indent is arranged in the termination of inner wire 3; On a side of shell 1, a circular hole 10 is arranged, the center of this circular hole 10 is corresponding with the tip position of inner wire 3, have in the outside of circular hole 10 one with the side welding of shell 1, coaxial lead-in wire sleeve pipe 4 with circular hole 10, there is pressure welding case 8 outside at lead-in wire sleeve pipe 4, the diameter of bore of lead-in wire sleeve pipe 4 and the equal diameters of circular hole 10; The cavity 9 of said shell 1 inside connects the rear end face of shell 1, there is a profile insulator 6 identical to fill in the through hole of shell 1 rear end face with the cross sectional shape of cavity 9, the front end face of insulator 6 is close to the termination of inner wire 3, the rear end face of insulator 6 is deep in shell 1 rear end face, a screening cover 7 that profile is identical with the cross sectional shape of cavity 9 is arranged, and its overall dimension and cavity 9 keep interference fit.

Using method of the present utility model is: screening cover 7 was in released state with shell 1 with insulator 6 before welding.Earlier the inner wire of the radio frequency cable endoporus from lead-in wire sleeve pipe 4 is inserted in the cavity 9, is overlapped on the bonding wire groove 5 of inner wire 3, the through hole from shell 1 rear end face welds then.Again insulator 6 is filled in this through hole, with the port closed of screening cover 7 with this through hole.Because screening cover 7 is an interference fit with this through hole, can not come off.The thickness of screening cover 7 should guarantee that its outer surface flushes with the rear end face of shell 1.With pressure welding case 8 radio frequency cable is fixed at last.
