[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] like Figure 2-6 As shown, a new type of holding and sealing structure camera includes a metal back shell 1, an outer conductor 2, an insulator 3 and an inner conductor 4 from the outside to the inside.

[0024] like Figure 3As shown, the metal back shell 1 is provided with an inserting cavity 11 at the front end and a cavity 12 at the rear end, and the inserting cavity 11 and the cavity 12 are connected through an accommodating cavity 13 .

[0025] like Figure 4-6 As shown, the outer conductor 2 is tubular, has a simple structure and is easy to process.

[0026] The outer conductor 2 is axially inserted into the accommodating cavity 13 from the front end of the metal rear shell 1 , that is, from the plug-in cavity 11 , and the inner wall of the accommodating cavity 13 is adapted to the outer wall of the outer conductor 2 .

[0027] In the first embodiment, Figure 4 As shown, the diameter of the upper end of the outer conductor 2 is shrunk to adapt to the plug-in mating end of the corresponding caliber.

[0028] A metal sleeve 5 is fixed to the outer upper end of the outer conductor 2, and the contact surfaces of the two are fixed by welding or riveting.

[0029] The outer diameter of the metal sleeve 5 is consistent with the outer diameter of the lower end of the outer conductor 2. When the plug-in mating end is inserted into the plug-in cavity 11, the plug-in mating end just fits with the plug-in cavity 11, and the plug-in is stable and not easy to loosen.

[0030] In the second embodiment, as shown in FIG. 5 , a metal sleeve 5 is fixed to the inner wall of the upper end of the outer conductor 2, and the contact surfaces of the two are fixed by welding or riveting, so that the inner diameter of the upper end of the outer conductor 2 is reduced to adapt to the plug-in mating end of the corresponding caliber.

[0031] The inner wall of the accommodating cavity 13 is provided with a circle of shoulders 131 , which abut against the lower end of the outer conductor 2 , thereby limiting the insertion stroke of the outer conductor 2 .

[0032] like Figure 4 As shown in FIG. 5 , after the outer conductor 2 is matched with the accommodating cavity 13 in the metal rear shell 1 , the staff places a circle of tin wire 6 at the bottom of the plug-in cavity 11 for welding the metal rear shell 1 and the outer conductor 2 .

[0033] After welding is completed Figure 6 As shown, the outer periphery of the outer conductor 2 and a circle of connection at the bottom of the plug-in cavity 11 are fixedly connected by soldering, and the tin wire 6 melts and fills the gap between the metal rear shell 1 and the outer conductor 2, and forms a seal after cooling and solidification.

[0034] The connection between the cavity 12 and the accommodating cavity 13 is a bell mouth 132. The purpose of changing the shape of the back shell is that in the prior art, the lower end of the outer conductor 2 is in a bell shape to facilitate the matching of the internal connector with the inner conductor. After the inventor simplifies the structure of the outer conductor 2, although the outer conductor loses the function of facilitating the matching and plugging of the internal connector with the inner conductor, the metal back shell 1 compensates for this function by changing the structure of the metal back shell 1. In the prior art, the metal back shell 1 is formed by stamping, so the change in the structure of the metal back shell 1 will not complicate the processing technology of the metal back shell 1.

[0035] The inner conductor 4 is fixed in the outer conductor 2 by the insulator 3. The insulator 3 is formed by sintering glass or ceramics, and has good sealing effect and reliability.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
