The insulating bracket 15 also serves as an insulating base that prevents the center conductor 13b of the coaxial cable 3 from coming into contact with the earth clamp 14.

[0009]

[Problems to be solved by the device]

 However, in such a conventional coaxial connector 4, since the insulating cylindrical portion 8 of the coaxial connector main body 5 is formed to project corresponding to the length of the coaxial connector terminal 2, the coaxial connector from the bottom plate of the insulating housing 6 is formed. The main body 5 has a large protrusion length, the coaxial connector 4 has a large thickness, and when it is connected to the coaxial connector terminal 2, the protrusion degree becomes large, which is an obstacle.

[0010]

[Means for Solving the Problems]

 As a specific means for solving the above-mentioned problems, the present invention provides an insulating housing in which an insulating cylindrical portion of a coaxial connector main body is formed to project so that its connection port is opened to the outside, and the coaxial housing of the coaxial connector main body is provided in the insulating housing. A terminal portion provided at the rear end of the center conductor for electrically connecting to the center conductor of the coaxial cable, an outer conductor inserted into the coaxial connector body and prevented from coming off by a locking piece provided on the side surface, and the outer conductor A coaxial connector connected to a conductor and provided with an earth clamp for gripping an outer conductor of the coaxial cable, wherein a part of an insulating cylinder portion of the coaxial connector body is formed in the insulating housing. The coaxial connector is characterized in that the locking piece is positioned at a portion to be fitted with a mating coaxial connector terminal.

[0011]

[Action]

 In this way, by forming a part of the insulating tubular part of the coaxial connector body by being inserted into the insulating housing, and by locating the locking piece at the part that fits with the mating coaxial connector terminal, It is possible to shorten the protrusion length that protrudes to the outside of the connector body. Therefore, according to the present invention, it is possible to reduce the thickness of the coaxial connector.

[0012]

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. It should be noted that the same or corresponding parts as those in FIGS. 5 to 9 described above are designated by the same reference numerals and detailed description thereof will be omitted.

In the coaxial connector 4 of the present embodiment, the insulating cylindrical portion 8 of the coaxial connector body 5 is provided so that about 1/2 of its length is inserted into the insulating housing 6. Then, in order to maintain the insertion stroke of the counterpart coaxial connector terminal 2, the insulating bottom plate portion 9 is also retracted into the insulating housing 6 by the same size. The outer conductor 10 is fitted to the inner circumference of the insulating tubular portion 8 formed by being digged in this way to form a pair of legs 10a penetrating the insulating bottom plate portion 9 and side surfaces of the outer conductor 10. The locking piece 10b formed in the above is used to prevent it from coming off and being fixed. The locking piece 10b is located at a fitting portion with the mating coaxial connector terminal 2. For this reason, the protruding length of the insulating tubular portion 8 and the outer conductor 10 from the insulating housing 6 is shortened by the length of the protrusion into the insulating housing 6.

Further, the slit 11e provided on the terminal portion 11c of the central conductor 11 of the coaxial connector main body 5 enables electrical connection with the central conductor 13b of the coaxial cable 3 at the position of the locking protrusion 11d. It is deeply provided to the position between the left and right locking projections 11d. Therefore, the locking plate portion 11b and the terminal portion 11c are located at the same position, which is different from the conventional arrangement in which the positions are shifted in the longitudinal direction. Of the coaxial connector 4 can be shortened, and the thickness of the coaxial connector 4 can be reduced accordingly. The center conductor 11 of the coaxial connector body 5 can be fixed to the insulating boss 12 by insert molding.

In this embodiment, since the insulating tubular portion 8 is fitted in the window 14a of the earth clamp 14, the insulating bracket 15 is not necessary and is omitted.

[0016]

[Effect of the device]

 As described above, the coaxial connector according to the present invention is formed by inserting a part of the insulating cylindrical portion of the coaxial connector body into the insulating housing, and at the same time, engaging the engaging portion with the mating coaxial connector terminal. Since the one piece is positioned, the protruding length protruding outside the coaxial connector main body can be shortened by the amount by which the insulating cylinder portion is inserted. Therefore, according to the present invention, the thickness of the entire coaxial connector can be reduced.
