Description

Technical Field

[0001] This application relates to a USB socket connector. Background Art

[0002] The USB Type C interface is a standard interface applicable to the consumer electronics field, with high-speed transmission and large-current transmission capabilities, and supports the function of plugging in either direction, solving the defects of low transmission rate and non-support for plugging in either direction in existing traditional USBs. However, due to the small size of the USB Type C and the fact that the number of transmission terminals in the standard version reaches 24, the 24 transmission terminals are arranged in two rows corresponding to each other one by one, and a partition is provided between the two rows of transmission terminals. During injection molding, it is necessary to fix the transmission terminals and the partition. Therefore, multiple injection moldings are required to complete the manufacture of the product. Traditional USB Type C socket connectors generally require three injection moldings, that is, after fixing one row of transmission terminals and the partition, the first injection molding is carried out, the other row of transmission terminals is injection molded separately, and then the two are stacked and injection molded again to complete.

[0003] In some special products, through the optimized design of the product, it is also possible to achieve two injection moldings by reducing the number of some transmission terminals. For example, after removing 8 high-speed transmission terminals, there is more space at the rear of the docking tongue. The two rows of transmission terminals are fixed simultaneously by a dislocation method and then the first injection molding is carried out. However, there is still a problem that during the second injection molding, the plastic flow is not smooth, resulting in air bubbles. Therefore, during the first injection molding, a through hole that penetrates up and down is formed at the position of the plastic tongue of the first injection molding. Through this through hole, on the one hand, the flow performance of the plastic during the second injection molding can be improved, and on the other hand, the two rows of transmission terminals can be positioned and fixed through the position where the through hole is formed during the first injection molding. Since the two rows of transmission terminals of the USB Type C are arranged corresponding to each other in the up and down direction, the side edges in the thickness direction of the two corresponding terminals in the up and down direction are generally flush. Therefore, after the second injection molding, a plastic bonding seam that extends linearly in the up and down direction is formed at the side position of the two terminals in the up and down direction. During use, due to the liquid accidentally remaining on the tongue surface, it will penetrate along the plastic bonding seam in the up and down direction, thereby causing the risk of short circuit between the up and down transmission terminals.

[0004] Therefore, it is necessary to design a new USB socket connector to solve the above technical problems. Summary of the Invention

Apparently, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0069] In the description of the present application, it should be understood that the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those clearly listed steps or units, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0070] In addition, for the accuracy of the full text description of the present application, all directions involved in the full text of the present application shall be uniformly referred to Figure 1 Specifically, the direction where the X-axis is located is defined as the left-right direction; the direction where the Y-axis is located is defined as the up-down direction, where the positive direction of the Y-axis is up; the direction where the Z-axis is located is defined as the plugging and unplugging direction (the insertion and extraction direction of the docking module).

[0071] Please refer to Figures 1 to 15As shown, a USB socket connector disclosed in the present application includes a terminal module 100 and a metal housing 2 surrounding the terminal module 100. The terminal module 100 includes an insulating body 1 and a plurality of conductive terminals fixed on the insulating body 1. The insulating body 1 is sequentially provided with a tongue end portion 101 (the portion marked L2 in the attached drawing), a tongue root portion 102 (the portion marked L1 in the attached drawing), and a base portion 103 along the insertion and extraction direction of the docking module (not shown). The metal housing 2 is sleeved and fixed around the base portion 103 of the insulating body 1. The metal housing 2 and the terminal module 100 jointly form a docking space 1001 that is open at one end in the insertion and extraction direction. The tongue end portion 101 and the tongue root portion 102 jointly form a tongue portion and protrude forward in a cantilever shape from the front end surface of the base portion 103 toward the side where the docking space 1001 is located.

[0072] The plurality of conductive terminals are divided into an upper row terminal group 3 in a row and a lower row terminal group 4 in a row. Among them, the upper row terminal group 3 in a row is composed of a plurality of upper terminals 31. Each upper terminal 31 includes an upper fixing section 311 buried and fixed in the tongue root portion 102 and the base portion 103, an upper contact section 312 extending forward from the upper fixing section 311 and fixed in the tongue end portion 101, and an upper docking section 313 extending backward from the upper fixing section 311 and exposed outside the base portion 103. The lower row terminal group 4 in a row is composed of a plurality of lower terminals 41. Each lower terminal 41 includes a lower fixing section 411 buried and fixed in the tongue root portion 102 and the base portion 103, a lower contact section 412 extending forward from the lower fixing section 411 and fixed in the tongue end portion 101, and a lower docking section 413 extending backward from the lower fixing section 411 and exposed outside the base portion 103.

[0073] Among them: at least part of each upper contact section 312 is exposed upward from the upper surface of the tongue end portion 101 to form an upper contact portion 3121. At least part of each lower contact section 412 is exposed downward from the lower surface of the tongue end portion 101 to form a lower contact portion 4121. The upper contact portion 3121 and the lower contact portion 4121 are arranged in a one-to-one mirror symmetry along the up and down direction.

[0074] Please refer to Figures 2 to 8As shown, the insulating body 1 includes a first insulator 11 and a second insulator 12. The first insulator 11 is fixed with the upper terminal group 3 and the lower terminal group 4 by the first injection molding and together form a first assembly 110. The second insulator 12 is fixed with the first assembly 110 by the second injection molding. On the first assembly 110, a plurality of through holes 5 are formed at the tongue end 101 of the first insulator 11 in the up-down direction. In the left-right direction, the through hole 5 is located between two adjacent upper terminals 31. A barrier 51 is filled between the inner side wall of the through hole 5 and the side surface of the adjacent upper terminal 31 and the lower terminal 41. The barrier 51 is a part of the first insulator 11. The second insulator 12 fills and closes the through hole 5. The through hole 5 is used to improve the fluidity of the second insulator 12 during the second injection molding of the second insulator 12, and can also strengthen the bonding force between the molded second insulator 12 and the first assembly 110.

[0075] Please refer to Figures 2 to 4 As shown, after the second insulator 12 is fixedly combined with the first assembly 110 by the second injection molding, a plurality of joint seams 120 extending from top to bottom are formed between the second insulator 12 and the first assembly 110. The joint seams 120 are formed at the positions of the through holes 5. The setting of the blocking portion 51 can make the joint seams 120 at the corresponding positions extend in a non-linear path in the up-down direction. Therefore, during the use of the USB socket connector of the present application, even if a small amount of liquid infiltrates the surface of the tongue end 101, it is difficult to penetrate through the joint seams 120 in the up-down direction to conduct the upper terminal 31 and the lower terminal 41 to cause a short circuit risk.

[0076] Please refer to Figure 3 , Figure 7 , Figure 9 , Figure 12 and Figure 15 As shown, a plurality of through holes 5 are formed on the first insulator 11 between the upper contact portions 3121 of two adjacent upper terminals 31. Preferably, the through holes 5 are arranged in two rows along the plugging and unplugging direction. Since the thickness of the insulating body 1 at the tongue end 101 is thinner overall, the plastic fluidity at this position is the worst during injection molding. Therefore, the design of the plurality of through holes 5 can effectively improve the plastic fluidity and enhance the bonding force between the first insulator 11, the second insulator 12 and the conductive terminal.

[0077] Further, in a preferred embodiment of the present application, the barrier portion 51 is formed by a part of the first insulator 11 and fits on the plane where the side surfaces of the upper terminal 31 and / or the lower terminal 41 are located. Along the insertion and extraction direction, the barrier portion 51 extends and covers the entire length region of the side surfaces of the upper terminal 31 and / or the lower terminal 41 in the through-hole 5 region. In a preferred embodiment, the barrier portion 51 is located in the interval region between the upper terminal 31 and the lower terminal 41 corresponding to the upper terminal 31 in the up-and-down direction. In a preferred embodiment, the barrier portion 51 extends in the up-and-down direction and covers the interval region between the upper terminal 31 and the lower terminal 41. In a preferred embodiment, the barrier portion 51 covers at least a partial position in the up-and-down direction of the side surfaces of the upper terminal 31 and / or the lower terminal 41.

[0078] Please refer to Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, in a preferred embodiment of the present application, along the insertion and extraction direction, the upper contact portion 3121 is formed at the middle position of the upper contact section 312, and both ends of the upper contact section 312 except the upper contact portion 3121 are buried in the second insulator 12 at the tongue end portion 101. Along the insertion and extraction direction, the lower contact portion 4121 is formed at the middle position of the lower contact section 412, and both ends of the lower contact section 412 except the lower contact portion 4121 are buried in the second insulator 12 at the tongue end portion 101. The free end of the upper contact section 312 of the upper terminal 31 further extends forward along the insertion and extraction direction out of the first insulator 11 to form an upper terminal positioning portion 3120. The free end of the lower contact section 412 of the lower terminal 41 further extends forward along the insertion and extraction direction out of the first insulator 11 to form a lower terminal positioning portion 4120. The upper terminal positioning portion 3120 and the lower terminal positioning portion 4120 are arranged at intervals in the left-right direction, and the upper and lower surfaces of the upper terminal positioning portion 3120 and the lower terminal positioning portion 4120 are exposed outside the first insulator 11 for positioning a plurality of the upper terminals 31 and a plurality of the lower terminals 41 during the first injection molding of the first insulator 11. In addition, in an embodiment of the present application, the rear end positions of the upper fixing section 311 of the upper terminal 31 and the rear end positions of the lower fixing section 411 of the lower terminal 41 are also arranged to be misaligned or partially misaligned in the left-right direction (which can be combined with Figure 3 , Figure 7 and Figure 8 As shown), which is also used for positioning a plurality of the upper terminals 31 and a plurality of the lower terminals 41 during the first injection molding of the first insulator 11.

[0079] Furthermore, along the insertion and extraction direction, each of the upper terminals 31 defines an upper bonding section (not shown, which refers to the part where the upper terminal 31 and the first insulator 11 are integrally bonded and fixed in this embodiment, including parts of the upper fixing section 311 and the upper contact section 312) integrally bonded with the first insulator 11. Each of the lower terminals 41 defines a lower bonding section (not shown, which refers to the part where the lower terminal 41 and the first insulator 11 are integrally bonded and fixed in this embodiment, including parts of the lower fixing section 411 and the lower contact section 412) integrally bonded with the first insulator 11. In a preferred embodiment of the present application, the barrier portion 51 extends along the insertion and extraction direction and covers the entire length region of the upper bonding section and / or the lower bonding section.

[0080] In the USB socket connector of the present application, several upper terminals 31 include upper signal terminals, upper ground terminals, and upper power terminals. Several lower terminals 41 include lower signal terminals, lower ground terminals, and lower power terminals. Specifically, several upper terminals 31 are arranged in sequence in the left-right direction as: one upper ground terminal, one upper power terminal, four upper signal terminals, one upper power terminal, and one upper ground terminal. Several lower terminals 41 are arranged in sequence in the left-right direction as: one lower ground terminal, one lower power terminal, four lower signal terminals, one lower power terminal, and one lower ground terminal. The USB socket connector of the present application is a non-full Pin architecture USB Type C connector. The barrier portion 51 is at least provided between the planes where the side surfaces of any two adjacent upper terminals 31 are located and / or between the planes where the side surfaces of any two adjacent lower terminals 41 are located. Among them, the extension paths in the up-down direction of the bonding seams 120 corresponding to the side surfaces of any one of the upper signal terminals and / or upper power terminals are all non-linear.

[0081] In a preferred embodiment of the present application, the barrier portion 51 is at least provided in the region of the tongue end portion 101. The first insulator 11 does not expose the second insulator 12 in the region of the tongue end portion 101. The first insulator 11 forms a plurality of positioning portions 1012 exposed outside the second insulator 12 in the region of the tongue root portion 101.

[0082] Please refer to Figure 3 、 Figure 9 and Figure 12As shown, it mainly shows the structure of the through hole 5 provided on the tongue end portion 101. Blocking portions 51 are formed at the positions of the two upper terminals 31 and the two lower terminals 41 on both sides of the position of the through hole 5. The blocking portions 51 combined on the same side of the upper terminal 31 and the lower terminal 41 corresponding up and down cover a part of one side of the upper terminal 31, a part of one side of the lower terminal 41, and all areas between the upper terminal 31 and the lower terminal 41 in the vertical direction. Of course, in other embodiments, the blocking portions 51 combined on the same side of the upper terminal 31 and the lower terminal 41 corresponding up and down cover at least a partial area between the upper terminal 31 and the lower terminal 41 in the vertical direction. In a preferred embodiment, blocking portions 51 are provided on both sides of the through hole 5.

[0083] Please refer to Figure 3 、 Figure 10 and Figure 13 As shown, it mainly shows the structure at the position on the tongue end portion 101 where the through hole 5 is not provided. In a preferred embodiment, blocking portions 51 are also provided between two adjacent upper terminals 31 and two adjacent lower terminals 41 at the position where the through hole 5 is not provided (as shown in Figure 13 ), so as to achieve an overall extension with the blocking portions 51 at the position where the through hole 5 is formed. Of course, in other embodiments, blocking portions 51 may not be provided at the position on the tongue end portion 101 where the through hole 5 is not provided, and the first insulator that blocks the upper terminal 31 and the lower terminal 41 in the vertical direction is regarded as the blocking portion 51.

[0084] Please refer to Figure 3 、 Figure 11 and Figure 14 As shown, it mainly shows the structure of the through hole 5 provided on the tongue root portion 102. The upper terminal 31 and the lower terminal 41 on any one side of the position of the through hole 5 are arranged in a dislocation manner in the left-right direction. A blocking portion 51 is provided on one side of the upper terminal 31, and the blocking portion 51 extends downward to the upper surface of the lower terminal 41. The bonding seam 120 formed between the upper terminal 31 and the corresponding lower terminal 41 at the inner wall surface position of the through hole 5 (the through hole 5 is filled with the second insulator 12) has a non-linear extension path in the vertical direction. Of course, in other embodiments, a blocking portion 51 may also be formed on the inner side surface of the lower terminal 41. It only needs to satisfy that the extension path of the bonding seam 120 at the corresponding position is non-linear in the vertical direction.

[0085] By implementing the USB socket connector of the present application, during use, even if a small amount of liquid infiltrates the surface of the tongue end portion 101, it is very difficult to penetrate along the vertical direction through the bonding seam 120 to conduct the upper terminal 31 and the lower terminal 41, resulting in a risk of short circuit.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention.
