DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0028] Embodiment: please refer to Figures 1 to 7 According to the embodiment of the utility model, a technical scheme is provided: a USB C single-row 24pin high-speed transmission connector, comprising: upper row of terminals 1; lower row of terminals 2; middle clamp 3, the middle clamp 3 can be injection molded into clamp MD semi-finished product 4, the clamp MD semi-finished product 4 both sides correspond to the terminal path both sides of upper row of terminals 1 and lower row of terminals 2 and are fixed with limiting protrusion 5, limiting protrusion 5 forms fixed groove 6 between, upper row of terminals 1 and lower row of terminals 2 can be pressed and embedded into fixed groove 6; connecting piece 7, after upper row of terminals 1 and lower row of terminals 2 are embedded into clamp MD semi-finished product 4, can be embedded into connecting piece 7, one end of connecting piece 7 is socket 8, upper row of terminals 1 and lower row of terminals 2 can partially expose socket 8 and contact with electrical equipment; shell 9, which wraps and protects connecting piece 7.

[0029] The connector with the above structure is assembled by using the upper row of terminals 1 and the lower row of terminals 2 in the fixing groove 6 formed by the limiting protrusion 5 of the clamp MD semi-finished product 4 injection molded by the middle clamp 3, and the overall structure is completed by twice combination (i.e., the first injection molding is performed on the middle clamp 3, and then the second injection molding is performed after the upper row of terminals 1 and the lower row of terminals 2 are embedded in the fixing groove 6). The difference from the three-time molding or multiple-time molding structure on the market is that the process is optimized and the bonding surface caused by injection molding is reduced under the premise of meeting the product structure and functional requirements, which facilitates automatic production and product quality control.

[0030] In order to better connect with other components, conduct current, or realize signal transmission in the future, the lower row of terminals 2 and the upper row of terminals 1 are fixed at one end in the same direction, and the contact plate 10 is provided with a connection hole 11 that overlaps each other. When in use, the corresponding connecting piece 7, pin, or the like can be inserted into the overlapping connection hole 11 to ensure that the connector is better connected with the external electrical equipment to realize stable and effective connection, so as to meet the functional requirements such as high-speed transmission.

[0031] During the machine pressing process, i.e., the automatic assembly machine presses the lower row of terminals 2 and the upper row of terminals 1 into the fixing groove 6 on both sides of the clamp MD semi-finished product 4, the terminal end of the lower row of terminals 2 and the upper row of terminals 1 is prone to bending. At this time, the other end of the lower row of terminals 2 and the upper row of terminals 1 in the same direction is fixed with a disassembling piece 12, which fixes the terminal part of the lower row of terminals 2 and the upper row of terminals 1. After the two injection moldings are completed or after the complete assembly is completed, the disassembling piece 12 is removed. The disassembling piece 12 and the terminal connection part can be provided with a water gap (a certain gap generated when the pouring piece is formed), which can be broken by high-frequency vibration of the water gap knife in the water gap cutting device, or can be cut, broken, etc. Preferably, it is performed after the clamp MD semi-finished product 4 is connected with the connecting piece 7. At this time, the shell 9 does not wrap the connecting piece 7, and it is easier to operate.

[0032] The terminal part of the lower row of terminals 2 and the upper row of terminals 1 is in a Z shape, which is more conducive to arranging the terminal path in a limited space, so that it can better adapt to other components inside the connector, such as the middle clamp 3, the connecting piece 7, etc. Cooperate and install to avoid space conflicts.

[0033] The terminal parts of the lower row of terminals 2 and the upper row of terminals 1 are each a group of four terminals, and the terminal parts of the upper row of terminals 1 and the lower row of terminals 2 are staggered, which can reduce the mutual interference of signals between adjacent terminals, so that the signals can be transmitted more orderly and stably, ensuring the quality of high-speed transmission, and the staggered arrangement can make the terminals more reasonably and compactly distributed in limited space, better adapt to the space structure inside the connector, facilitate the cooperation with other components such as the middle clamping piece 3 and the connecting piece 7, thereby ensuring the compactness and integrity of the entire connector structure, and also facilitating subsequent assembly and other production operation processes.

[0034] The clamping piece MD semi-finished product 4 is fixed with a plurality of limiting blocks 13, and the connecting piece 7 is provided with a plurality of limiting openings 14 matched with the limiting holes, so that when the upper row of terminals 1 and the lower row of terminals 2 are embedded in the clamping piece MD semi-finished product and then assembled with the connecting piece 7, the two can be tightly and accurately combined together through the cooperation of the limiting blocks 13 and the limiting openings 14, avoiding installation position deviation and the like, which helps to improve the accuracy and stability of the entire connector assembly, thereby ensuring the reliability of the overall structure of the connector and the performance in subsequent use.

[0035] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
