Detailed Description
In the description of the present invention, it should be understood that the directions or positional relationships indicated by the terms "left", "right", "upper", "lower", "front", "rear", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.
In the following, the present invention will be described in further detail with reference to the specific embodiment, and fig. 2 shows an assembly schematic diagram of the coaxial connector of the present invention, where the male socket 1 is inserted into the female socket 2, and the core shaft thereof is always abutted against the female socket terminal, so as to realize transmission of power or signals.
Fig. 3 and 4 are perspective views of a circular conductive socket according to the present invention, which mainly include a socket insulator 21, a socket cover 22, a socket terminal 23, and a shield case 24, wherein the socket insulator 21 has a cavity structure. The shielding shell 24 is a sheet metal structure and wraps the periphery of the female base insulator 21. The female terminal 23 is composed of a conduction portion 231, a support portion 232, and an elastic connection portion 233 in this order from top to bottom. The elastic connection portion 233 is fixed directly under the support portion 232 (as shown in fig. 9). The conductive portion 231 includes a plurality of conductive claws 2311 extending upward from the side wall of the supporting portion 232 and uniformly distributed in the circumferential direction (as shown in fig. 10), and accordingly, a receiving cavity 221 (as shown in fig. 8) for receiving the conductive claws 2311 is provided on the base cover 22. The female cap 22 is not in contact with the female insulator 21 at all, and is supported only by the female terminal 23. The conducting claw 2311 is elastically abutted against the side wall of the accommodating cavity 221 all the time, and is provided with a circular arc-shaped conducting surface consistent with the outer diameter of the pre-insertion mandrel. In this way, the conductive portion 231 of the female terminal 23 and the mandrel are in a linear contact relationship (as shown in fig. 5), so that the reliability and stability of contact are greatly improved, and the stability of power and signal transmission is ensured.
It should be noted that, in the technical scheme disclosed in the present invention, the number of the conducting claws 2311 is set to 3, and circumferential uniform distribution is performed at intervals of 120 °. Of course, the specific number of the conductive claws 2311 may be selected according to the actual situation.
As a further optimization of the annular conductive female socket, the following specific arrangement may be made for the elastic connection portion 233: which is composed of one connecting arm 2331 and two free arms 2332 (as shown in fig. 10) distributed around the lower end of the support 232. Wherein, the upper end of the connecting arm 2331 is fixed on the supporting part 232, and the lower end is fixed on the female base insulator 21; the upper end of the free arm 2332 is also fixed to the support 232, while the lower end thereof is horizontally disposed and not fixed to the female insulator 21. In this way, when the male socket 1 is inserted into the female socket 2, the female socket cover 22 can be finely adjusted in position in the X direction, the Y direction, and/or the Z direction with respect to the female socket insulator 21 by means of the elastic connection portion 233, so that the mandrel has a correct insertion position with respect to the conductive portion 231.
The floating principle of the annular conduction master seat is as follows: when the male socket 1 of the coaxial connector and the female socket 2 of the coaxial connector are inserted, the mandrel fixed on the male socket 1 applies force to the female socket terminal 23, and at the same time, the elastic connection portion 233 is adaptively deformed or tilted, so that the female socket cover 22 can be finely adjusted in position along the X direction, the Y direction and/or the Z direction, and the mandrel has a correct insertion position with respect to the conductive portion 231 of the female socket terminal 23. Therefore, the coaxial connector matching piece is effectively prevented from being damaged due to rigid assembly, and the signal transmission stability is further affected. In addition, the influence of vibration, impact and the like on the connection reliability of the coaxial connector can be eliminated to a certain extent.
In order to reduce the number of welding positions and reduce the manufacturing cost, the connecting arm 2331 and the free arm 2332 are formed by extending the side wall of the supporting portion downward, and may be formed by bending.
In order to enhance the connection strength of the female terminal 23 to the female insulator 21, a slot 211 (as shown in fig. 6) may be formed in the inner wall of the cavity of the female insulator 21 for inserting and fixing the connecting arm 2331, and a recess 23311 may be formed in the connecting arm 2331.
Moreover, in order to improve the connection strength between the female cover 22 and the female terminal 23 and to facilitate the detachment, the side wall of the supporting portion 232 may be provided with a bayonet 2421 (as shown in fig. 10), and the corresponding side wall of the female cover 22 may be provided with a slot 222 (as shown in fig. 7) adapted to the bayonet 2421.
Furthermore, the stopper 223 (as shown in fig. 7) may be further disposed on the female base cover 22, and the number of stoppers is preferably 2, and the stoppers are formed by extending the bottom wall of the female base cover 22 along the left and right directions, so as to effectively prevent the female base terminal 23 from being damaged due to the excessive inserting force of the male base 1 (i.e. the elastic connection portion 233 of the female base terminal 23 will generate excessive deformation when receiving excessive inserting force, thereby causing the elastic connection portion to lose itself).
In addition, as shown in fig. 11, in order to make the male housing 1 perform the insertion of the female housing 2 more smoothly, elastic guide plates 241 may be provided at both sides of the female housing 2 to provide a guiding function for the downward movement of the male housing 1. The preferred embodiments are: the two elastic guide plates 241 are formed by extending upward from the left and right side walls of the shield case 24, respectively, and are each provided with an inward curved guide surface 2411 at the free ends thereof.
In view of the structural weight reduction, the weight reduction grooves 2412 may be provided in both the elastic guide plates 241 to reduce the weight of the female seat 2 as much as possible.
Finally, it should be emphasized that, in the process of actually performing the insertion of the male socket 1 into the female socket 2, it is found that when the inclination angle of the mandrel exceeds a certain range, the stability of the female socket terminal 23 may be drastically reduced, so as to affect the floating effect, and for this purpose, the two elastic guide plates 241 may be provided with press-shaped limiting protrusions 2413, where the number of the press-shaped limiting protrusions 2413 is not less than 2 for a single elastic guide plate 241, and are uniformly distributed along the front-rear direction of the above-mentioned arc-shaped guide surface 2411. In this way, the existence of the press-shaped limiting protrusion 2413 can effectively control the insertion angle of the male base 1 relative to the female base 2, and improve the stability of the female base terminal 23 in the floating process.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
