Abstract
The utility model relates to a coaxial cable connector used for connecting two cable terminals in microwave transmission equipment. The connector comprises a hollow conductive shell, wherein through an annular insulator, the inner wall of the shell is connected with a contact pin positioned at the center of the shell, the insulator is positioned on the middle section of the shell, the external diameter of the rear end of the insulator is small, an annular solder bath is formed between the rear end of the outer wall of the insulator and the inner wall of the shell, and the rear section of the shell is a connection section of which the inner wall is provided with a helical flute matched with ripples of an outer conductor of a coaxial cable. The utility model can greatly enhance the strength and the electric contact performance of the connection of the connector and the terminal of the coaxial cable, and has the advantages of simple connection structure and connection technology, convenient processing and reduced manufacturing cost.
Description
Technical field
The utility model relates to a kind of coaxial cable connector that two sections cable sockets are connected of being used in microwave transport equipment.
Background technology
In microwave transport equipment, the quality of connection of coaxial cable termination is to the electrical property important influence of whole transmission system, and the key of quality of connection is the bonding strength and the contact reliability of connector and cable segment connector.Common coaxial cable connector generally comprises a hollow external conductive casing, outer casing inner wall is connected with the contact pin that is positioned at the center by the insulator of annular, the leading portion of shell is provided with and is used for the external screw thread or the internal thread that are connected with other coaxial cable connector, and the back segment of shell then is connected with the coaxial cable termination by a cover mechanical clamp gripping member.Because this class formation mainly is connected with the termination of coaxial cable by the mode of machine mechanical grip, its coupling part parts are more, structure is complicated, therefore not only improve difficulty of processing, increased cost, and the bonding strength that electricity touches part reliability lower, contact is relatively poor, in use take place to connect easily touch bad, thereby influence the reliability of whole microwave transmission system.
Summary of the invention
Technical problem to be solved in the utility model is a kind of simple in structure, easily manufactured coaxial cable connector to be provided, but to make it be easier to obtain higher bonding strength height and electrically contact performance preferably when being connected with the coaxial cable termination.
Coaxial cable connector of the present utility model comprises the shell of a hollow conduction, outer casing inner wall is connected with the contact pin that is positioned at the center by the insulator of annular, the leading portion of shell is provided with and is used for the external screw thread or the internal thread that are connected with other coaxial cable connector, the insulator of described annular is positioned at the shell stage casing, the rear end external diameter of insulator is less, thereby between insulator outer wall rear end and outer casing inner wall, constitute an annular welds molten tin bath that is used for laying solder stick, the back segment of shell is to be used for the linkage section that coaxial cable connects, and is having one section helicla flute that matches with ripple on the coaxial cable outer conductor on the inwall of linkage section.In addition, on the outer wall of shell, also can have an aperture that communicates with above-mentioned helicla flute, be used in helicla flute, replenishing scolding tin.
The utility model has improved the intensity and the electrical contact performance that connect greatly owing to can realize being connected of connector and coaxial cable termination by welding manner, and its syndeton of while has reduced manufacturing cost with to be connected technology simple, easy to process.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model and coaxial cable termination connection status.
Embodiment
As shown in Figure 1, the leading portion of the shell 1 of coaxial cable connector of the present utility model is identical with common coaxial cable connector structure, is provided with to be used for the external screw thread that is connected with other connector or internal thread (being shown in the figure internal thread 8).Shell 1 is fixing by exhausted edge 3 separations of annular with the contact pin 2 at center, contracts in the external diameter of insulator rear end, constitutes the solder bath 4 of an annular.The shell back segment is the linkage section 5 that is connected with the coaxial cable termination, with one section linkage section inwall of above-mentioned solder bath next-door neighbour on have helicla flute 6.
As shown in Figure 2, when connector is connected with the termination of coaxial cable 9, the termination of coaxial cable is inserted the linkage section 5 of connector, the center conductor 91 of coaxial cable passes insulator 3 centers and is connected with the contact pin 2 of connector, 92 of the outer conductors of coaxial cable are screwed in the helicla flute by its outside ripple, then by welding equipment in the shell external heat, make 10 fusings of the solder stick that is placed in advance in the solder bath 4 and flow in the gap between helicla flute and the coaxial cable outer conductor, realize that welding is fixing.In this process, also can in helicla flute, replenish scolding tin by opening at the aperture on the shell 7.
Claims (2)
1, a kind of coaxial cable connector, comprise a hollow external conductive casing (1), outer casing inner wall is connected with the contact pin that is positioned at the center (2) by the insulator (3) of annular, it is characterized in that: insulator is positioned at the shell stage casing, the rear end external diameter of insulator is less, constitute the solder bath (4) of an annular between insulator outer wall rear end and outer casing inner wall, the back segment of shell is linkage section (5), has one section helicla flute (6) on the inwall of linkage section.
2, coaxial cable connector according to claim 1 is characterized in that: have an aperture (7) that communicates with helicla flute (6) on the outer wall of shell (1).
