The utility model content
The purpose of this utility model is to overcome existing defective, a kind of simple in structure, cable reliable clamping and the low coaxial cable bent radio-frequency coaxial connector of cost is provided, and has had good electric property.
The utility model is to realize like this, a kind of bent radio-frequency coaxial connector, comprise bent angle shape outer conductor always, described outer conductor center offers a cavity, be provided with an inner wire that can be connected in this cavity with cable, between described inner wire and described outer conductor, be provided with one and be used for the insulating part that described inner wire supports is isolated and be can be used as to inner wire and outer conductor; The end that described outer conductor is provided with inner wire also is connected with a rear thread sleeve, and described rear thread sleeve front end places in the described outer conductor cavity, which is provided with a flexible clamp piece that is used for fixing cable.
Particularly, offer a groove in the cavity of described outer conductor, described insulating part places in this groove.
Particularly, described rear thread sleeve front end offers an annular opening groove, and described flexible clamp piece places in the described open slot.
Particularly, described outer conductor inner chamber is provided with a stop surface, and described flexible clamp piece is positioned at the annular cavity of this stop surface and open slot formation.
Further, described stop surface is an inclined-plane.
Preferably, described flexible clamp piece is a wound spring.
The utility model is used for the insulating part that described inner wire supports is isolated and be can be used for to inner wire and outer conductor by be provided with one in the outer conductor cavity, one flexible clamp piece that is used for fixing cable is set simultaneously, can replace the wire clamp in the prior art structure, flexible clamp piece is not only simple in structure, manufacturing cost is also cheap than wire clamp, can meet the need of market, can also reduce the waste of copper material resource, shared space is also very little, can shorten the length of outer conductor, thereby make the structure of whole connector compact more, and alleviated its weight, provide cost savings.And flexible clamp piece compares to the easier assembling of wire clamp, and the quality of production is stable, be connected simple and reliablely with cable, the clamping performance is good, and good electric property is arranged, its return loss has reached 27.3dB by original 20.8dB, has improved the competitiveness of product on market.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram.
Fig. 2 is the schematic diagram that the utility model is connected with feeder line.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The utility model embodiment provides a kind of bent radio-frequency coaxial connector.Referring to Fig. 1, it comprises bent angle shape outer conductor 2 always, and described outer conductor 2 centers offer a cavity, and this cavity connects whole elbow, in the cavity of described outer conductor 2, be provided with an inner wire 3, these inner wire 3 front ends place outer conductor 2 near the elbow center position, and the rear end is connected with cable, between described inner wire 3 and described outer conductor 2, be provided with an insulating part 1, this insulating part 1 can also can be used as the positioning support of inner wire 3 with inner wire 3 and outer conductor 2 isolated insulations on the one hand; The end that described outer conductor 2 of while is provided with inner wire 3 also is connected with a rear thread sleeve 6, these rear thread sleeve 6 front ends offer screw thread, can screw and place in described outer conductor 2 cavitys, and by a seal 5 sealings, described rear thread sleeve 6 front ends, also be provided with a flexible clamp piece 4 that is used for fixing cable, constitute with inner wire 3 that cable is connected and fixed structure.Like this, by in outer conductor 2 cavitys, insulating part 1 being set, one flexible clamp piece 4 is set simultaneously, just can replaces the wire clamp in the prior art structure to fix cable, because flexible clamp piece 4 is simple in structure, and manufacturing cost is lower than wire clamp, so can reduce the waste of copper material resource, can shorten the length of outer conductor, thereby make the structure of whole connector compact more, alleviate its weight, saved processing cost.And flexible clamp piece 4 is to be arranged on the rear thread sleeve 6, compares to the easier assembling of wire clamp, owing to have certain elasticity, and therefore very simple with being connected of cable, and can guarantee reliable clamping.
In the utility model concrete structure design, offer a groove in the cavity of described outer conductor 2, described insulating part 1 places in this groove, can guarantee that insulating part 1 installs accurately and fix.
Preferably, flexible clamp piece 4 described in the utility model is a wound spring, also can adopt shell fragment shape fastener, and described wound spring internal diameter is consistent with the groove external diameter of cable outer conductor, wales the groove difficult drop-off of cable outer conductor.Adopt wound spring on the one hand because the elasticity that it had can guarantee the cable firm grip, on the other hand,, help cutting down finished cost because wound spring is generally standard component.
