[0017] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings.

Specific Embodiments

[0018] Refer Figures 1 - 8 As shown, the present invention is a coaxial connector 100 mounted on a circuit board. In this embodiment, the coaxial connector is of a vertical type, that is, the docking connector can be inserted in a vertical direction perpendicular to the circuit board. In other embodiments, the coaxial connector can be of a right-angle type, that is, the docking connector can be inserted in a horizontal direction parallel to the circuit board. For convenience of description, the docking face of the coaxial connector is defined as the front face hereinafter.

[0019] Refer Figure 7 As shown, the coaxial connector 100 includes an inner conductor 10, an outer conductor 20, and an insulating jacket 30. The inner conductor 10 includes a docking portion 11 and a connecting portion 12. The outer conductor 20 includes a base portion 21 and a tubular portion 22 extending forward from the base portion 21. The base portion is in a rectangular shape. Refer Figures 4 - 5 As shown, the docking portion 11 of the inner conductor is located inside the tubular portion 22 and forms a coaxial relationship; the insulating jacket 30 is fixed to the base portion 21 of the outer conductor and surrounds the tubular portion 22 to form a forward-penetrating insertion space 31. The insulating jacket is provided with a fastening opening 32 for fastening a locking elastic arm provided on a docking connector.

[0020] Refer Figures 1 - 7 As shown, the coaxial connector 100 further includes a protective cover 40. The protective cover is detachably covered on the front opening of the insertion space 31. The protective cover 40 can effectively prevent foreign objects from entering the insertion space of the coaxial connector, especially into the tubular portion, to avoid causing adverse consequences. In combination with Figure 6As shown, the protective cover 40 includes a cover plate portion 41 and elastic arms 42, and the elastic arms are provided with a fastening portion 421. When the protective cover is installed on the insulating jacket 30, the cover plate portion 41 covers the front opening of the insertion space 31, and the fastening portion 421 of the elastic arm is locked in the fastening opening 32; the user can directly press the elastic arm 42 to release the fastening portion 421 from the fastening opening. Combining Figure 6 , the protective cover 40 includes an insertion portion 43 extending rearward from the cover plate portion 41, the elastic portion 42 is formed by extending forward from the rear end of the insertion portion 43, and the elastic arm 42 is further provided with an operation portion 422 located at the front end of the fastening portion 421. The cover plate portion 41 is provided with a notch 411, and the operation portion 422 is received in the notch 411 or passes through the notch 411. In this embodiment, the operation portion 422 and the cover plate portion 41 are in the same plane, so as to play a protective role without additional space. The outer conductor is provided with two tubular portions 22, and a matching space 431 for accommodating the two tubular portions 22 is formed in the insertion portion 43 of the protective cover. The elastic arm 42 is provided with a rib 423 on its outer side surface, and the front end surface of the rib 423 is spaced from one end of the operation portion 422 to form the fastening portion. In a specific embodiment, the rearward-facing wall surface in the fastening opening 32 constitutes a fastening surface that cooperates with the fastening portion.

[0021] When the protective cover 40 is installed on the insulating jacket 30, the insertion portion 43 is inserted into the insertion space 31, the cover plate portion covers the front opening of the insertion space, and the fastening portion 421 of the elastic arm is locked in the fastening opening 32. The user directly presses the operation portion 422, and the elastic arm 42 deflects to cause the fastening portion 421 to disengage from the fastening opening. In this embodiment, the fastening opening of the insulating jacket is not only used for the elastic arm of the docking connector to be fastened, but also for the fastening portion of the protective cover to be fastened. In this way, the electrical connector does not need to additionally add a fastening structure for matching the protective cover. In this embodiment, when the protective cover is inserted, the fastening portion of the elastic arm directly completes the self-locking work, and directly pressing the elastic arm can unlock the reverse buckle to achieve quick disassembly and assembly.

[0022] Refer Figures 7 - 9 As shown, the electrical connector 100 includes an insulating base 50, combining Figure 5As shown, the inner conductor 10 is fixed to the insulating base 50, and its butt joint portion 11 and the lead portion 12 respectively extend out of the insulating base 50. In this embodiment, the insulating jacket 30 and the insulating base 50 are integrally injection-molded from an insulating material. More specifically, the base portion 21 of the outer conductor 2 is provided with a fixing hole 231 communicating with its tubular portion 22, a ring groove 232 around the outer periphery of the base portion 21, and a connection channel 233 connecting the ring groove 232 and the fixing hole 231. The connection channel 233 penetrates backward through the bottom surface of the base portion 21 to facilitate the injection of the insulating material. After the inner conductor 10 is positioned in the fixing hole 231 and the tubular portion 22, the insulating material is injected from the bottom surface of the base portion 21, enters the fixing hole, the ring groove, and the cavity formed by the mold. The insulating material fills the fixing hole 231 to form the insulating base 50, and fills the ring groove 232, the connection channel 233, and the cavity to form the insulating jacket 30. The integral injection molding of the insulating jacket 30 and the insulating base 50 increases the holding force between the two and the inner and outer conductors, avoids the risk of detachment, and the integral molding process can reduce the assembly process and lower the product assembly cost.

[0023] In summary, the above is only the preferred embodiment of the present invention, and should not be used to limit the scope of the present invention. That is, all simple equivalent changes and modifications made according to the claims and the content of the specification of the present invention should still be within the scope covered by the patent of the present invention.
