Abstract
The utility model discloses a knurled screw sleeve of a radio-frequency coaxial connector. The knurled screw sleeve includes a body which is made of a zinc alloy material, and the body is formed through hole boring, thread cutting and slot cutting after die molding. The body is formed through twice hole boring and then thread cutting and slot cutting. The knurled screw sleeve is formed by utilizing a die, so that the processing steps are reduced and the cost is saved. The weight of the knurled screw sleeve is reduced to 7g from 9g in the past, and the material cost is reduced to 0.2 RMB/piece from 0.7 RMB/piece in the past.
Description
Technical field
The utility model relates to a kind of radio frequency (RF) coaxial connector, specifically a kind of annular knurl swivel nut of radio frequency (RF) coaxial connector.
Background technology
Radio frequency (RF) coaxial connector (hereinafter to be referred as the RF connector) is to be installed on the cable or to be installed in a kind of element on the instrument; The element that is electrically connected or separates as transmission line; Be the important component part of electric connector, develop at present to standardization, seriation, generalization direction.
Radio frequency (RF) coaxial connector leans on mechanical structure to guarantee electrical characteristic, and part processing mainly is turning machine processing, and assembling handwork is many, is difficult to carry out the automation assembling, belongs to the labor-intensive product that certain technology content is arranged.
Along with the miniaturization of machine system, the volume of RF connector is more and more littler, frequency is increasingly high, function is more and more.Except that serving as a connection, have the function of processing signals concurrently, like filtering, phase modulation position, mixing, decay, detection, amplitude limit etc.The RF connector requires low standing wave, low-loss to come the needs of sufficient armament systems and accurate measurement.Require big capacity, the high-power development need that adapts to information superhighway simultaneously.
At present, the material of radio frequency (RF) coaxial connector swivel nut is the Hpb59-1 annular knurl rod of Φ 20, and manufacturing procedure is: blanking, plane, car external diameter, 2 bore holes, bolt die, kerve, chamfering.Processing technology is complicated, and cost is high.And weight is 9g greatly, and material cost is also high to be 0.7 yuan/part.
Summary of the invention
In order to practice thrift cost, reduce manufacturing procedure, the purpose of the utility model provides a kind of annular knurl swivel nut of radio frequency (RF) coaxial connector, and this swivel nut uses mould molding, has reduced manufacturing procedure, has practiced thrift cost.
The purpose of the utility model realizes through following technical scheme:
A kind of annular knurl swivel nut of radio frequency (RF) coaxial connector comprises body, it is characterized in that: the body that said zinc alloy material is processed obtains through bore hole and bolt die, kerve after by mould molding.
The said body of the utility model through behind twice bore hole again the flat surface grinding obtain.
Compared with prior art, the utility model uses mould molding by zinc alloy material, reduces difficulty of processing, has reduced by 4 road manufacturing procedures, has practiced thrift cost.It is about 30% to improve production capacity, and product weight further reduces by 22%, makes product lightweight more, reduces material cost simultaneously up to 71%, and the utility model weight is reduced to 7g by original 9g, and material cost is reduced to 0.2 yuan/part by 0.7 yuan original/part.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
The annular knurl swivel nut of the described radio frequency (RF) coaxial connector of a kind of the utility model is seen Fig. 1, and this swivel nut comprises body 1, and the body of being processed by zinc alloy material 1 is through obtain through twice bore hole and bolt die, kerve behind the mould molding again.
The utility model uses mould molding, changes the swivel nut material into kirsite, and manufacturing procedure is than original 4 roads that reduce, and only needs can obtain through 2 bore holes and bolt die, kerve, has practiced thrift cost, has improved production capacity.
Claims (2)
1. the annular knurl swivel nut of a radio frequency (RF) coaxial connector comprises body (1), it is characterized in that: the body that said zinc alloy material is processed (1) is by obtaining through bore hole, bolt die and kerve behind the mould molding.
2. the annular knurl swivel nut of radio frequency (RF) coaxial connector according to claim 1, it is characterized in that: said body (1) obtains through twice bore hole.
