Abstract

A radio frequency coaxial connector comprises a male connector and a female connector which can be inserted into the male connector. A recess (7) is provided on the housing (1) of the female connector. A through slot (18) is provided on the housing (16) of the male connector. A spring piece (10) is mounted in the through slot (18) so as to cooperate with the recess (7) by locking when the female connector is inserted into the male connector. A sliding block (9) is provided between the housing (16) and the pressing sleeve (8) and can slide on the axial direction. When the disconnection of the connectors is desirable, the sliding block (9) contacts with the spring piece (10) to release the locking cooperation between the spring piece (10) and the recess (7). The spring piece (10) is locked into the recess (7) to achieve self-locking when the female connector is inserted into the male connector. When unlocking is desirable, the pressing sleeve (8) is pushed so as to force the sliding block (9). The inclined planes of the sliding block (9) force and open the spring piece (10), so the female connector can be pulled out from the male connector.

Description

RF coaxial connector

The invention relates to a radio frequency coaxial connector. Background technique

It has strong shock resistance, high reliability, excellent mechanical and electrical properties, and is widely used. Connect RF coaxial cables to radios, communications equipment and instruments. However, since the interface of the product is a threaded connection, rapid insertion and removal is not possible, and special tools are required in the assembly process, which wastes time and cannot be rotated arbitrarily after installation. Summary of the invention

The technical problem to be solved by the present invention is to provide a radio frequency coaxial connector with high reliability, excellent mechanical and electrical performance, and fast plug-in self-locking function in order to overcome the shortcomings in the prior art.

The technical solution of the present invention is: an RF coaxial connector comprising a male connector and a female connector insertable into the male connector, the female connector having four slots on the housing; The outer casing of the male connector is provided with a through groove, and the reed is snapped into the through groove to be snap-fitted with the groove when the female connector is inserted into the male connector; The space between the sleeve and the sleeve is provided with a slider that is axially slidable to release the snap fit of the spring and the groove when the connector is required to be separated.

The positive effects produced by the technical solution of the present invention are: The connector is improved on the basis of the threaded connector structure, and retains the advantages of high power, good shock resistance, high reliability, excellent mechanical and electrical performance. It can also realize fast plugging and self-locking functions, save time, reduce assembly space and reduce assembly cost during assembly. It can be widely used in radio equipment, communication equipment and instruments to connect RF coaxial cable.

The RF coaxial connector includes a male connector and a female connector. As shown in Figure 1, when the female connector is inserted into the male connector, the connection between the two is established. When the female connector is pulled out of the male connector, disconnect the two.

As shown in Fig. 2, the female connector of the present invention includes a housing 1, and the housing 1 has an end face 5. In the casing 1, an insulator 2 is provided along the inner wall of the casing 1. A socket 3 is also provided in the housing 1. On the outer surface of the casing 1, a circumferentially extending groove 凸 and a boss 6 are provided, and the groove 7 and the boss 6 are connected by a joint face 4.

Referring to Figure 3, the male connector includes a tubular outer casing 16, and a compression sleeve 8 is provided at the end of the outer casing to form an axial space between the outer casing 16 and the compression sleeve 8. The pressure sleeve is slidably coupled to the outer casing. Sealing rings 11 and 13 are provided on the inner surface of the outer casing. In addition, the male connector includes other conventional structures such as the insulator 12 and the pin 14. In the axial space between the press sleeve 8 of the male connector and the outer casing 16, a slider 9 is provided which is slidable along the axial direction of the outer casing 16, and the slider 9 is restrained by the pressure sleeve 8 on the outer wall of the outer casing 16. The slider 9 abuts against the axial inner surface of the press sleeve 8. This slider 9 is curved and has two sides with slopes 17, 17' (see Figure 4). Of course, those skilled in the art can also envision other shapes of the slider 9 that can achieve the object of the present invention.

Referring to Fig. 5, rectangular through grooves 18 are symmetrically provided on the outer surface of the tubular outer casing 16. Those skilled in the art can also design other through grooves according to actual needs. The two side edges 21, 21' of a U-shaped reed 10 are snap-fitted into the two through grooves 18 (see Fig. 8). The front end of the reed 10 is provided with two oblique fins 11, 22'. When the slider 9 is moved, the two inclined faces 17, 17' of the slider 9 can be in contact with the oblique fins 22, 22', when the movement is slippery Block 9, so that the two sides can be stretched to the sides Open. The reed 10 is also provided with a projection 20 which abuts against the radially inner surface of the compression sleeve 8 to prevent the reed 10 from sliding out of the radial direction when subjected to a force to increase the degree of engagement with the slider 9.

A circular ring coil with an intermediate opening is also placed at the inner bottom of the outer casing. Referring to Figs. 6, 7, the coil spring 15 is provided with a flange in the middle thereof, and its radial cross section is a figure-eight shape. When the female connector is inserted, the end face 5 directly presses the coil 15 to ensure the electrical connection performance of the connector.

The operation of the connector of the present invention will now be described with reference to FIG. When the female and male connectors are inserted, the two side edges 21, 2 of the reed 10 are pressed by the boss 6 on the female connector housing 1 to be flared to the sides. When the insertion is continued, the snap-fit is achieved by snapping into the recess 7 by the elastic action of the reed 10 to achieve the locking function. The reed 10 abuts against the connecting surface 4 to prevent the male and female connectors from being accidentally disengaged. To unlock, simply apply a small amount of force in the axial direction of the compression sleeve 8 and push the slider 9 to move the slider axially. The two inclined faces 17, 17' of the slider in turn press the two flaps 22, 22' on the reed 10, causing the reed 10 to open to the sides and out of the recess 7 on the female connector, thereby allowing the female The connector is pulled out of the male connector. As a result, the unlocking function is realized, the insertion and removal is very convenient, and the connection is very reliable.
