Description

Technical Field

[0001] This utility model relates to the field of transmission connector technology, and in particular to a high-definition transmission connector. Background Technology

[0002] According to the Chinese utility model patent application number CN202513386U, "High-speed transmission connector with multiple grounding terminals", "Currently, common high-speed transmission connectors, such as USB 3.0 connectors, contain 9 terminals, of which 4 terminals are USB 2.0 terminals, used for functional signal transmission and compatible with traditional USB 2.0 connectors; of the other 5 terminals, four are high-speed transmission terminals used in USB 3.0 transmission, and the other is a grounding terminal."

[0003] The USB 3.0 high-definition transmission connector is a connector specifically designed for high-definition video signal transmission. It features high bandwidth, low latency, and stable performance, and is widely used in high-end color printers, various PLC compilers, industrial robots, scanners, multi-functional docking stations, and other electronic products and equipment.

[0004] However, the current connector structure requires a lot of manual intervention during assembly. Excessive manual intervention can lead to a series of problems. First, manual operation is slow and inefficient, making it difficult to meet the pace and demands of large-scale production. Second, manual assembly makes it difficult to ensure the positional accuracy of each component, which may result in poor contact or reduced signal transmission performance. Furthermore, a large amount of manual labor will increase labor costs, leading to a significant increase in manufacturing costs.

[0005] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-definition transmission connector, comprising a core, 4P terminals, 5P terminals, a housing, and a back plug;

[0008] The core has an insertion interface at one end and a back plug at the other end. A core post is formed inside the insertion interface. The 4P terminal is inserted into the core and is distributed on both sides of the core post. The 5P terminal is inserted into the core and is fixed to one side of the inner wall of the insertion interface.

[0009] The two ends of the rubber core are interlocked with the two sides of the inner wall of the outer shell;

[0010] The rear plug has through holes corresponding to the pins of the 4P terminal and the 5P terminal. The upper and lower ends of the rear plug are provided with snap-fit ​​blocks. The upper and lower ends of the outer shell are provided with snap-fit ​​interfaces. The snap-fit ​​interfaces and snap-fit ​​blocks are engaged with each other.

[0011] The core and the rear plug are both integrally molded structures.

[0012] As a further embodiment of this utility model: both sides of the rubber core have clearance channels, and fastening protrusions are formed on the clearance channels. A slope is formed on one side of the fastening protrusions. Fastening plates are provided on both sides of the outer shell. The two fastening plates are arranged inwardly at an angle, and the angle of inclination is the same as the angle of the slope.

[0013] As a further embodiment of this utility model: the rear plug has multiple flared openings corresponding to the through holes on the side facing the rubber core, and the flared openings are in the shape of a four-sided pyramid, gradually narrowing from the side facing the rubber core to the other side.

[0014] As a further embodiment of this utility model: the edge of one side of the outer shell is processed with a cover edge by bending technology, and the bending of the cover edge makes one side of the outer shell form an opening that is consistent with the shape of the plug interface.

[0015] As a further embodiment of this utility model: the left and right sides of the outer shell away from the rear plug are bent inward with clamping pieces, and the clamping pieces have arc-shaped protrusions.

[0016] As a further embodiment of this utility model: the rubber core also has notches on both sides corresponding to the two clamping pieces.

[0017] As a further embodiment of this utility model: the outer shell is provided with fasteners on both sides near the rear plug end.

[0018] Compared with existing technologies, the beneficial effects of this technical solution are as follows:

[0019] During assembly, first insert the 4P and 5P terminals into the core, then push the outer shell into the core from the direction of the insertion interface and cover the core. During this process, the two sides of the outer shell and the core are interlocked. Finally, assemble the back plug with the core, and splice the back plug opening of the core with the back plug opening. The pins of the 4P and 5P terminals are inserted into the through holes on the back plug, and the snap-fit ​​blocks at the upper and lower ends of the back plug are interlocked with the snap-fit ​​interface of the outer shell, thereby fixing the core, outer shell and back plug assembly.

[0020] The overall assembly process of this utility model is simple and quick, with few steps. At the same time, the core and the rear plug are both integrally molded structures, which makes the assembly of this utility model better adaptable to automated equipment production, helps to improve production efficiency, meet the needs of large-scale production, improve the production precision and uniformity of products, and reduce manufacturing costs.

[0021] Meanwhile, the integrated rear plug design can improve the sealing of the rubber core and combine with the outer shell to achieve a dustproof effect, improving the dustproof performance of the product while adapting to automated equipment production.

[0022] Furthermore, considering that in the actual production process, the position of the pins of the 4P and 5P terminals after assembly with the core is difficult to guarantee to be the same every time, there will be cases where the pins and the through holes of the back plug are not aligned. Therefore, a flared opening in the shape of a four-sided pyramid is designed to connect with the through hole. The four-sided pyramid shape means that there are four inclined surfaces that taper towards the middle inside the flared opening. When the position of the terminal pins and the through holes are not aligned, the inclined surfaces of the flared opening can guide the pins so that the pins and the through holes can be interlocked.

[0023] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-4 A high-definition transmission connector includes a core 1, a 4P terminal 2, a 5P terminal 3, a housing 4, and a back plug 5;

[0033] One end of the core 1 has an insertion interface 11 and the other end has a rear plug 12. A core post 13 is formed inside the insertion interface 11. A 4P terminal 2 is inserted into the core 1, and the 4P terminals 4 are distributed on both sides of the core post 13. A 5P terminal 3 is inserted into the core 1, and the 5P terminal 3 is fixed to one side of the inner wall of the insertion interface 11.

[0034] The two ends of the core 1 are interlocked with the two sides of the inner wall of the outer shell 4;

[0035] The rear plug 5 has through holes 51 corresponding to the pins of the 4P terminal 2 and the 5P terminal 3. The upper and lower ends of the rear plug 5 are provided with snap-fit ​​blocks 52. The upper and lower ends of the outer shell 4 are provided with snap-fit ​​interfaces 41. The snap-fit ​​interfaces 41 and snap-fit ​​blocks 52 are engaged with each other.

[0036] Both the rubber core 1 and the rear plug 5 are integrally molded structures.

[0037] Specifically, during assembly, the 4P terminal 2 and 5P terminal 3 are first inserted into the core 1. Then, the outer shell 4 is pushed into the core 1 from the direction of the insertion interface 11 and covers the core 1. During this process, the two sides of the outer shell 4 are interlocked with the core 1. Finally, the rear plug 5 is assembled with the core 1. The rear plug 5 and the rear plug opening 12 of the core 1 are spliced ​​together. The pins of the 4P terminal 2 and 5P terminal 3 are inserted and engaged with the through holes 51 on the rear plug 5. The snap-fit ​​blocks 52 at the upper and lower ends of the rear plug 5 are snapped together with the snap-fit ​​interface 41 of the outer shell 4, thereby assembling and fixing the core 1, the outer shell 4 and the rear plug 5.

[0038] The overall assembly process of this utility model is simple and quick with few steps. At the same time, the core 1 and the rear plug 5 are both integrally molded structures, which makes the assembly of this utility model better adaptable to automated equipment production, helps to improve production efficiency, meet the needs of large-scale production, improve the production precision and uniformity of products, and reduce manufacturing costs.

[0039] Meanwhile, the integrated rear plug design can improve the sealing of the rear end of the rubber core 1 and combine with the outer shell 4 to achieve a dustproof effect, improving the dustproof performance of the product while adapting to automated equipment production.

[0040] In this embodiment, reference Figure 4 Furthermore, it is proposed that both ends of the core 1 have clearance channels 14, and fastening protrusions 15 are formed on the clearance channels 14. A slope 16 is formed on one side of the fastening protrusions 15. Fastening plates 42 are provided on both ends of the outer shell 4. The two fastening plates 42 are set inwardly at an angle, and the angle of inclination is the same as the angle of the slope 16.

[0041] Specifically, during the assembly of the outer shell 4, the clearance channel 14 on the side of the core 1 provides space for the snap-fit ​​plate 42 inside the outer shell 4. When the snap-fit ​​plate 42 abuts against the inclined surface 16 of the snap-fit ​​protrusion 15, the interaction force causes the snap-fit ​​plate 42 to deform and pass over the snap-fit ​​protrusion 15. After the snap-fit ​​plate 42 passes over the snap-fit ​​protrusion 15, it elastically recovers, so that the snap-fit ​​plate 42 and the other side of the snap-fit ​​protrusion 15 snap together, thereby assembling and fixing the outer shell 4 and the core 1 together.

[0042] In this embodiment, reference Figure 3 Furthermore, it is proposed that the rear plug 5 has multiple flared openings 53 corresponding to the through holes 51 on the side facing the rubber core 1. The flared openings 53 are in the shape of a four-sided pyramid, gradually narrowing from the side facing the rubber core 1 to the other side.

[0043] Specifically, considering that in the actual production process, after the 4P terminal 2 and 5P terminal 3 are assembled with the core 1, it is difficult to ensure that the position of their pins is the same every time. Therefore, there will be cases where the pins are not aligned with the through hole 51 of the back plug 5. Therefore, a flared opening 53 in the shape of a four-sided pyramid is designed to connect with the through hole 51. The four-sided pyramid shape means that the flared opening 53 has four inclined surfaces that taper towards the middle. When the terminal pins are not aligned with the through hole 51, the inclined surfaces of the flared opening 53 can guide the pins so that the pins can be inserted and matched with the through hole 51.

[0044] In this embodiment, reference Figure 3 Furthermore, it is proposed that the edge of one side of the outer shell 4 is processed with a cover edge 43 by bending technology, and the bending of the cover edge 43 makes one side of the outer shell 4 form an opening that is consistent with the shape of the insertion interface 11.

[0045] Specifically, after assembling the outer shell 4 and fastening the fastening plate 42 and the fastening protrusion 15, the cover edge 43 formed by the bending technology of the outer shell 4 abuts against the core 1 to improve the tightness of the outer shell 4 to the core 1 and prevent the core 1 from loosening. At the same time, after bending the cover edge 43, an opening with the same shape as the insertion interface 11 is formed on one side of the outer shell 4. While tightening the core 1 to the maximum extent, it does not affect the normal use of the insertion interface 11.

[0046] In this embodiment, reference Figure 3 Furthermore, it is proposed that the left and right sides of the outer shell 4, which are away from the rear plug 5, are bent inward and have clamping pieces 44, which have arc-shaped protrusions.

[0047] Specifically, after the connector is assembled, the two clamping pieces 44 are located on both sides inside the insertion interface 11 of the core 1. When the male connector is inserted into the insertion interface 11, the two clamping pieces 44 deform under pressure using the arc-shaped protrusion structure, which has a similar effect to the spring. The clamping force when the clamping pieces 44 recover their elasticity improves the tightness of the insertion between the male connector and the insertion interface 11, preventing the male connector from accidentally loosening.

[0048] Preferably, the core 1 also has notches 17 on both sides corresponding to the two clamping tabs 44.

[0049] Specifically, the two notches 17 provide space for the deformation of the clamping piece 44, allowing the male connector to be inserted into the interface 11 more smoothly.

[0050] In this embodiment, reference Figure 2 Furthermore, it is proposed that the outer shell 4 has fasteners 6 on both sides near the rear plug 5.

[0051] Specifically, when the connector is assembled and put into use, the pins of 4P terminal 2 and 5P terminal 3 are led out from the rear plug 5, and the pins are soldered to the circuit board or connected to the wires. The rear latch 6 can be fastened into the opening on the circuit board, providing an additional connection point for the connector, thereby improving the connector's robustness.

[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
