[0022] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0023] In the prior art, some connectors may have problems such as loose, unstable or insecure connections, and may be disconnected, especially in a vibration environment.
[0024] In view of the above problems, combined with reference Figures 1 to 4 As shown, the medical connector proposed by the utility model includes:
[0025] A male socket 10, the male socket 10 comprising a first base 11 and an insertion wall 12 protruding from one end surface of the first base 11, the insertion wall 12 forming an insertion cavity 121 inside, a tongue plate 122 disposed inside the insertion cavity 121, and upper and lower end surfaces of the tongue plate 122 respectively arranged with wiring terminals 1221 in an alternating manner; and
[0026] The female socket 20 includes a second base 21 and a docking wall 22 protruding from an end face of one side of the second base 21. A receiving cavity 221 is formed inside the docking wall 22. The upper and lower inner walls of the receiving cavity 221 are respectively arranged with elastic sheets 222 alternately. When the plug-in wall 12 is inserted into the outer side of the docking wall 22, the tongue plate 122 is inserted into the receiving cavity 221, and the wiring terminals 1221 are respectively abutted against the elastic sheets 222.
[0027] Combined with reference Figure 1As shown, it can be understood that the first base 11 can be an elliptical, square or rectangular substrate, on which pins can be arranged to connect to an external circuit board or a power cord, and the end surface of the first base 11 on one side away from the pin can be integrally formed with a plug-in wall 12 with a cross-sectional shape of a ring, square or trapezoid, and the plug-in wall 12 is enclosed inside to form a plug-in cavity 121, and a tongue plate 122 can be arranged in the plug-in cavity 121. The tongue plate 122 can be a plate-like structure in a square, trapezoidal or other shape, and the upper and lower surfaces of the tongue plate 122 can be staggered with a plurality of wiring terminals 1221, which can be strip-shaped metal sheets used as connection points for current, signals, data, etc.
[0028] Combined with reference Figure 2 As shown, similarly, the second base 21 can be set with the same shape, size and material as the first base 11, and the end face of the second base 21 on one side away from the plug pin can also be integrally formed with a docking wall 22 with a cross-sectional shape of an annular, square or trapezoidal shape. The inner diameter and circumference of the docking wall 22 are smaller than the inner diameter and circumference of the plug-in wall 12, and a receiving cavity 221 is formed inside the docking wall 22. The cross-sectional shape of the receiving cavity 221 can be annular, square or trapezoidal, and elastic sheets 222 are alternately arranged on the upper and lower inner wall surfaces of the receiving cavity 221 for docking with the wiring terminal 1221 to transmit current, signals, data, etc.
[0029] When the male socket 10 and the female socket 20 are connected, the plug-in wall 12 is inserted into the outer side of the docking wall 22, the tongue plate 122 is inserted into the receiving cavity 221, and the connection terminals 1221 are respectively in contact with the elastic sheet 222, and the elastic sheet 222 is in a compressed state and locked to the connection terminals 1221 under the action of the force of restoring deformation. In this way, the male socket 10 and the female socket 20 have a plug-in fit between the plug-in wall 12 and the docking wall 22, between the tongue plate 122 and the receiving cavity 221, and between the tongue plate 122 and the elastic sheet 222, so that the connection between the male socket 10 and the female socket 20 is more stable and firm, and is not easy to loosen, especially in a vibrating environment.
[0030] Combined with reference Figure 1 and Figure 2 As shown, further, in one embodiment of the present application, the inner wall surface of the plug-in cavity 121 is provided with a limiting rib 123 along its plug-in direction; the outer wall surface of the docking wall 22 is provided with a limiting groove 223, and when the plug-in wall 12 is inserted into the outer side of the docking wall 22, the limiting rib 123 is inserted into the limiting groove 223.
[0031] In order to improve the stability and convenience of the connection between the male socket 10 and the female socket 20, and to prevent the tongue plate 122 from being damaged due to the incorrect plugging method of the male socket 10 and the female socket 20, a limiting rib 123 can be protruded on the inner wall surface of the plug-in cavity 121 along its plug-in direction, and a limiting groove 223 can be provided at a corresponding position on the outer wall surface of the docking wall 22. When the plug-in wall 12 is inserted into the outer side of the docking wall 22, the limiting rib 123 is plugged into the limiting groove 223. In addition to the aforementioned functions, the plug-in cooperation of the limiting rib 123 and the limiting groove 223 can further enhance the stability of the plug-in between the male socket 10 and the female socket 20.
[0032] Combined with reference Figure 2 As shown, in one embodiment of the present application, a sinking groove 224 is provided at the connection between the docking wall 22 and the second base 21 , and when the plug-in wall 12 is inserted into the outer side of the docking wall 22 , the outer edge of the plug-in cavity 121 is embedded in the sinking groove 224 .
[0033] The sinking groove 224 is recessed downward relative to the end surface of the second base 21, forming an annular groove with a shape similar to the periphery of the docking wall 22. When the plug-in wall 12 is inserted into the outer side of the docking wall 22, the outer edge of the plug-in cavity 121 is embedded in the sinking groove 224, which can not only help enhance the stability of the connection between the male seat 10 and the female seat 20, but also play a sealing role at the connection between the male seat 10 and the female seat 20, which can prevent dust and water.
[0034] Combined with reference Figure 2 As shown, in one embodiment of the present application, a baffle 225 is provided on one side of the sinking groove 224, and the baffle 225 and the outer wall surface of the docking wall 22 form a clamping space, and part of the plug-in wall 12 is inserted into the clamping space.
[0035] Furthermore, on one side of the sinking groove 224, for example, a baffle 225 can be integrally formed on one side of the short side of the sinking groove 224, and the baffle 225 and the outer wall surface of the docking wall 22 form a clamping space, so that part of the plug-in wall 12 is inserted into the clamping space, which can further enhance the stability of the connection between the male socket 10 and the female socket 20.
[0036] Combined with reference Figure 4 As shown, in one embodiment of the present application, a portion of the elastic sheet 222 close to the edge of the docking wall 22 has at least three bending points 222 a so that the elastic sheet 222 bulges toward the inside of the receiving cavity 221 .
[0037] It can be understood that the portion of the elastic sheet 222 close to the edge of the receiving cavity 221 has at least three bending points 222a, so that the elastic sheet 222 is partially folded outward and then retracted inward, so that the elastic sheet 222 bulges toward the inside of the receiving cavity 221, thereby increasing the clamping force of the elastic sheet 222 on the tongue plate 122, which can not only enhance the stability of the connection between the elastic sheet 222 and the terminal 1221, but also enhance the stability of the connection between the receiving cavity 221 and the tongue plate 122.
[0038] Combined with reference Figure 3 As shown, in one embodiment of the present application, the elastic sheet 222 is provided with a protrusion 222b, and the two side edges of the protrusion 222b are arranged in mirror symmetry and protrude a plurality of protrusions outward respectively.
[0039] It can be understood that the installation of the elastic sheet 222 can open a plurality of straight grooves inside the receiving cavity 221, and the elastic sheet 222 can be clipped and fixed in the straight grooves. In order to enhance the stability of the connection between the elastic sheet 222 and the straight grooves, a protrusion 222b can be provided on the elastic sheet 222, and the two side edges of the protrusion 222b are arranged in a mirror-symmetrical manner, and a plurality of protrusions protrude outward respectively, so that the elastic sheet 222 can be clipped and fixed on the inner wall of the straight groove, thereby enhancing the stability of the connection between the elastic sheet 222 and the receiving cavity 221, and further enhancing the stability of the connection between the tongue plate 122 and the receiving cavity 221.
