Abstract

The utility model discloses a bending type radio frequency coaxial connector which comprises a first housing, a second housing, a pin, a pressure sleeve, a pressure cover, an insulator, a clasp, a sealing ring, a thread sleeve and a thermal contraction sleeve. A double step groove is arranged at the mounting position of the clasp on the inner wall of the thread sleeve. The advantage of the utility model is that a knife point R arc left by the processing of the groove is completely eliminated in the area of mounting the elastic part clasp, so that the clasp can fully stretch to be clung in the groove and is not liable to shed.

Description

The bent radio-frequency coaxial connector

Technical field

The utility model relates to a kind of connector, is a kind of bent radio-frequency coaxial connector specifically.

Background technology

Radio frequency (RF) coaxial 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.It belongs to electromechanical integrated product, mainly serves as a connection.

The swivel nut of existing bent radio-frequency coaxial connector makes snap ring come off in use easily, can not satisfy U.S. military connector standard M-C-39012---the minimum endurance square of product 1.7Nm.

The utility model content

Goal of the invention: in order to overcome the deficiency of prior art, the purpose of the utility model is to provide a kind of bent radio-frequency coaxial connector rational in infrastructure.

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 bent radio-frequency coaxial connector; Comprise first shell body, second shell body, contact pin, pressure welding case, gland, insulator, snap ring, sealing ring, swivel nut and heat shrinking sleeve, the position that snap ring is installed on said swivel nut inwall is provided with the double step groove.

Said first shell body and second shell body are Stainless Steel Shell.

Said first shell body and the second shell body vertical fixing.

Beneficial effect: the utility model compared with prior art; Have the following advantages: in the zone that the elastic part snap ring is installed, eliminated the point of a knife R arc of being left over when processing this groove fully, can make the complete spread apart of snap ring reach the purpose of its difficult drop-off to be close in the groove.

Fig. 2 is the structural representation of swivel nut among Fig. 1;

Fig. 3 is the local enlarged diagram at A place among Fig. 2.

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.

Extremely shown in Figure 3 like Fig. 1; A kind of bent radio-frequency coaxial connector of the utility model; Be made up of first shell body 1, second shell body 2, contact pin 3, pressure welding case 4, gland 5, insulator 6, snap ring 7, sealing ring 8, swivel nut 9 and heat shrinking sleeve 10, the position that snap ring 7 is installed on swivel nut 9 inwalls is provided with double step groove 11.

First shell body 1 in the utility model, second shell body 2 are Stainless Steel Shell and both form the shell of an integral body through the welding vertical fixing.

Evidence, the variable quantity of welding back accessory size are satisfied the endurance square that dimension precision requirement welds between back 2 parts fully and can be reached 6Nm in 0.005mm, satisfy the mechanical performance requirement fully.

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.
