Abstract

The utility model discloses a low-pass intermodulation jack connector, comprising an inner conductor, a jack, an insulator and an outer conductor, wherein a sealing ring is arranged between the inner conductor and the insulator, and an outer wall of the inner conductor is provided with two holes having the same direction, the same aperture and different depths. Advantages of the low-pass intermodulation jack connector are that the sealing ring can guarantee that waterproof and dustproof grade of the low-pass intermodulation jack connector can reach IP68, and the two holes arranged at the outer wall of the inner conductor can guarantee that the connector can be welded with other components to realize a device function.

Description

A kind of low pass intermodulation receptacle connector

Technical field

The utility model relates to a kind of electric elements, is a kind of 7/16 type low pass intermodulation receptacle connector specifically.

Background technology

7/16 type low pass intermodulation receptacle connector is mainly used in all kinds of filters, is used for the signal screening of all kinds of GSMs, digital microwave communication system, military microwave system (radar and electronic countermeasures).As output and being connected of input port, have characteristics such as bandwidth, the insertion loss is low, power capacity is big.Filter be a kind of in microwave device indispensable microwave device, therefore, be of the all-round opening of the supporting radio frequency (RF) coaxial connector of filter along with 3G market, its market prospects are very wide.Because filter cavity structural reason; Such radio frequency (RF) coaxial connector in the market; The moulding of its inner wire is to be welded to form the inner wire of a resonant rod (inner wire) with connector after being made into shape by connector device again; Owing to the reason of weld jig precision and part carry out the negative effect that high-temperature soldering causes quality of coating after electroplating, between the inner wire of connector and the resonant rod coupling discrete excessive, increased filter install, difficulty in the debug process; Cause filter assembly period long, qualification rate is on the low side, corresponding filter manufacturing cost is higher.

The utility model content

Goal of the invention: in order to overcome the deficiency of prior art, the purpose of the utility model be to provide a kind of rational in infrastructure, can improve the low pass intermodulation receptacle connector of outer conductor mechanical strength and electrical property transmission.

Technical scheme: in order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of low pass intermodulation receptacle connector, comprise inner wire, jack, insulator, outer conductor, and be provided with sealing ring between inner wire and the insulator.

On the outer wall of said inner wire, be provided with the hole of two same in the same way footpath different depths.

In order to make the minimum torsional moment of being born between inner wire and the outer conductor is 15Ncm, said inner wire and said insulator interference fit.Said insulator and said outer conductor interference fit.On the outer wall of the inwall of said outer conductor and inner wire, be provided with the hangnail structure of anti-spline.

For economical with materials, said jack and said inner wire are for dividing body structure.

Beneficial effect: the utility model compared with prior art has the following advantages: between inner wire and insulator, adopt the sealing ring design, the water proof and dust proof grade that can guarantee product is IP68; On the outer wall of inner wire, be provided with two in the same way with the hole of footpath different depth, can this connector and other components and parts be welded back realization device function through these two holes.Become the mode of two inner wires that originally need welding through mechanical connection integrated, made consistency of product be guaranteed, and can stop high temperature the ⑶ complete machine qualification rate that influences of part quality of coating is obviously promoted.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Embodiment

Below in conjunction with accompanying drawing, the utility model is done further to specify, but the protection range of the utility model is not limited to said embodiment.

As shown in Figure 1, a kind of low pass intermodulation of the utility model receptacle connector comprises inner wire 1, jack 2, insulator 3, outer conductor 4, is provided with sealing ring 5 between inner wire 1 and the insulator 3.On the outer wall of inner wire 1, be provided with two in the same way with the hole 6 of footpath different depth, these two holes 6 mainly are to weld the back with other components and parts to realize device function.

Inner wire 1 and insulator 3 interference fit, insulator 3 and outer conductor 4 interference fit are provided with the hangnail structure of preventing spline on the outer wall of the inwall of outer conductor 4 and inner wire 1, and can make the minimum torsional moment of being born between inner wire 1 and the outer conductor 4 like this is 15Ncm.

Jack 2 materials are beryllium-bronze in the utility model, and inner wire 1 material is a brass, and split-type structural is taked in connection between the two, can save material like this.

The processing of above-mentioned inner wire 1 adopts Digit Control Machine Tool one preface to accomplish, and is regardless of preface, thereby can guarantees the precision of product, realizes the device function of product LPF.

As stated, although represented and explained the utility model that with reference to specific preferred embodiment it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the utility model that does not break away from the accompanying claims definition, can make various variations in form with on the details to it.
