Detailed Description

In the description of the present invention, it is to be understood that the terms "left", "right", "front", "rear", "upper", "lower", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

In the following, the contents of the present invention will be further described in detail with reference to specific embodiments, and fig. 1 and fig. 2 respectively show an explosion diagram and an assembly perspective diagram of an assembly structure of a dual-interface high-speed transmission electrical connector according to the present invention, and it can be understood that the assembly structure mainly includes a male base portion 1, a female base portion 2, a first PCB 3 and a second PCB 4. Wherein, the male seat part 1 and the female seat part 2 are inserted and combined along the front and back direction. The male seat part 1 and the female seat part 2 are respectively fixed with the first PCB board 3 and the second PCB board 4 in a one-to-one correspondence manner and are electrically connected. As shown in fig. 5-11, the male socket portion 1 includes a male insulating plastic body 11 and a tongue assembly 12. The tongue assembly 12 at least includes a first tongue 121 and a second tongue 122, and correspondingly, the male insulating plastic body 11 is provided with a first accommodating cavity 111 and a second accommodating cavity 112 arranged along the left-right direction for respectively accommodating the first tongue 121 and the second tongue 122. The female socket 2 includes a female insulating plastic body 21 and a socket assembly 22. The socket assembly 22 includes at least a first socket 221 and a second socket 222. The first socket 221 and the second socket 222 are respectively corresponding to and inserted into the first insertion tongue 121 and the second insertion tongue 122, and are both embedded into the female insulating plastic body 21. In this way, a dual interface design of the electrical connector is realized, so that the electrical connector has the function of simultaneously transmitting different types of signals. For example: the USB TYPE-C interface and the PCIE interface are taken as examples for explanation: the USB TYPE-C interface and the PCIE interface are combined in parallel for use, wherein the USB TYPE-C interface can provide functions of charging, image output, audio, data transmission and the like; the synchronous PCIE can provide functions of an external memory, a wireless network card, a display card and the like. The USB TYPE-C interface and the PCIE interface can work synchronously or separately. In addition, by adopting the technical scheme for arrangement, the design size of the dual-interface high-speed transmission electric connector assembling structure can be effectively reduced, the cost advantage is good, and the required assembling space can be effectively reduced.

In practical applications, the first socket 221 and the second socket 222 are inserted into the first receiving cavity 111 and the second receiving cavity 112, respectively, and have shapes matched with the first receiving cavity 111 and the second receiving cavity 112. In order to ensure that the male socket 1 and the female socket 2 have high stability after being plugged, and further ensure the stability of signal transmission, as a further optimization of the assembly structure of the dual-interface high-speed transmission electrical connector, the fit clearance between the male socket 1 and the female socket 2 needs to be limited, specifically as follows: after the female seat portion 2 is completely inserted into the male seat portion 1, the single-sided gaps between the first socket 221 and the first tongue 121 and between the second socket 222 and the second tongue 122 are controlled within 0.1mm in the left-right direction. Along the up-down direction, the unilateral gaps between the first socket 221 and the first insertion tongue 121 and between the second socket 222 and the second insertion tongue 122 are controlled within 0.08 mm.

As a further optimization of the above technical solution, the female seat 2 may further include a first guide arm 23 and a second guide arm 24 according to actual conditions. The first guide arm 23 and the second guide arm 24 are formed by extending the rear sidewall of the female insulating plastic body 21 backward, are symmetrically arranged along the left-right direction, and exceed the socket assembly 22 by a predetermined distance. Correspondingly, a first slot 113 adapted to the first guiding arm 23 and a second slot 114 adapted to the second guiding arm 24 extend from the front side wall of the male insulating plastic body 11 backward (as shown in fig. 7-10). Therefore, when the male seat portion 1 and the female seat portion 2 are inserted and closed, the first guide arm 23 and the second guide arm 24 first contact the male insulating plastic body 11, and then the first insertion tongue 121 and the second insertion tongue 122 respectively enter the insertion and closing stage with the first socket 221 and the second socket 222, thereby effectively avoiding the occurrence of the phenomena of collision or abrasion caused by misalignment of the male seat portion 1 and the female seat portion 2.

In order to ensure that the first guide arm 23 and the second guide arm 24 enter the first slot 113 and the second slot 114 more smoothly and improve the insertion efficiency of the electrical connector as much as possible, a guide inclined surface 231 (as shown in fig. 9) may be further formed around the free end of the first guide arm 23. The second guide arm 24 is implemented with reference to the structural form of the first guide arm 23 described above.

In the practical application process of the electrical connector, it is known that the excitation force or the external pulling force is inevitably applied to the electrical connector, so that the male seat portion 1 is easily separated from the female seat portion 2. Specific embodiments are recommended as follows: the female seat 2 is additionally provided with a first elastic clamping piece 25 and a second elastic clamping piece 26. The first elastic clip 25 includes a first fixing section 251, a first elastic section 252 and a first clip hook 253 connected in sequence. A first assembly cavity 211 is formed in the female insulating plastic body 21 and extends to the first guide arm 23. The first fixed segment 251 and the first elastic segment 252 are disposed in the first assembly cavity 211, and the first elastic segment 252 can freely swing in the first assembly cavity 211. The first snap hook 26 is formed by extending the free end of the first elastic section 25 and is exposed a distance outside the side wall of the first assembly cavity 211. A first clamping slot 1131 adapted to the first clamping hook 253 is formed on the inner side wall of the first slot 113. The second elastic clamping member 26 includes a second fixing section 261, a second elastic section 262 and a second clamping hook 263 connected in sequence. A second assembly cavity 212 is formed in the female insulating plastic body 21 and extends to the second guide arm 24. The second fixed section 261 and the second elastic section 262 are disposed in the second assembling cavity 212, and the second elastic section 262 can freely swing in the second assembling cavity 212. The second clamping hook 263 is formed by extending the free end of the second elastic segment 262 and is exposed out of the sidewall of the second assembling cavity 212 for a distance. A second clamping notch 1141 matched with the second clamping hook 263 is formed on the inner side wall of the second slot 114. Corresponding to the first elastic section 252 and the second elastic section 262, a first pressing notch 213 and a second pressing notch 214 (as shown in fig. 9-15) are formed on the sidewall of the female insulating plastic body 21. In this way, in the process of performing the insertion and assembly of the female seat 2 and the male seat 1, the first guide arm 23 and the second guide arm 24 respectively slide along the first slot 113 and the second slot 114, and in this process, the first clamping hook 253 and the second clamping hook 263 move back inward under the action of the pushing force of the side walls of the first slot 113 and the second slot 114 until entering the first clamping notch 1131 and the second clamping notch 1141 adapted thereto one by one (the first clamping hook 253 and the second clamping hook 263 elastically deform in a recovery manner), so as to realize the locking of the female seat 2 and the male seat 1; when the unlocking operation needs to be performed, the user holds the tool piece and applies force to the first elastic section 252 and the second elastic section 262 through the first pressing notch 213 and the second pressing notch 214 at the same time, so as to force the first snap-fit hook 253 and the second snap-fit hook 263 to move back inwards until the first snap-fit notch 1131 and the second snap-fit notch 1141 are completely disengaged.

However, the following difficulties exist in implementing the above technical solution: 1) the proper tool piece is not easy to find, and the unlocking operation of the electric connector is very inconvenient; 2) the first elastic section 252 and the second elastic section 262 are easily permanently plastically deformed due to improper force application by an operator. In view of this, the first elastic clip member 25 is additionally provided with a first pressing section 254. The first pressing section 254 is formed by extending and bending the sidewall of the first elastic section 252 and extends beyond the first pressing notch 213. The second elastic clip member 26 is additionally provided with a second pressing section 264. The second pressing portion 264 is formed by extending and bending the sidewall of the second elastic portion 262 beyond the second pressing notch 214 (as shown in fig. 9, 10, 14 and 15).

As shown in fig. 5 and 6, the male socket 1 is further provided with a metal shell 13 according to actual conditions. The metal shell 13 is connected between the male socket insulator 11 and the tongue assembly 12, and is in contact with the ground. Therefore, on one hand, the connection strength between the plugging component 12 and the male seat insulator 11 is effectively improved, and the phenomenon of shaking during plugging and actual application is avoided; on the other hand, the existence of metal shell 13 still makes public seat portion 1 self be in good shielding state all the time in practical application to can reduce the influence that external electromagnetic interference caused the signal transmission process effectively, ensure signal transmission's reliability and stability.

Generally, the metal shell 13 is also preferably laser welded to achieve the fixation with the male insulator 11. A series of laser welds (as shown in fig. 5) are distributed on the metal shell 13.
