Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a 20P connector structure. Background Technology

[0002] With the continuous development of society and the electronics industry, connectors, also known domestically as plugs, sockets, and connectors, generally refer to electrical connectors, which are devices that connect two active devices, allowing current or signals to flow from one conductor to another. Simply put, electronic connectors are components used to complete electrical connections between circuits or electronic machines, thus becoming a bridge between them. Connector forms and structures are ever-changing, and various forms of connectors exist depending on the application, frequency, power, and application environment.

[0003] Existing connectors typically include an insulating body and two rows of conductive terminals embedded in the insulating body. The two rows of conductive terminals include a contact portion, a connecting portion, and a soldering portion connected in sequence. The contact portion is exposed on the tongue portion of the insulating body, the connecting portion is fixed to the insulating body, and the soldering portion is exposed outside the insulating body. Furthermore, the connecting portion is usually exposed outside the insulating body, making it difficult to protect the exposed connecting portion. In addition, during the manufacturing process, the exposed connecting portion may be damaged by external objects, making it difficult to guarantee the processing quality.

[0004] Furthermore, the contact heights of the two existing rows of conductive terminals on the insulating base are inconsistent, which can easily lead to poor contact due to uneven force during insertion and removal, affecting the stability of signal transmission.

[0005] Furthermore, this type of connector lacks an effective guiding and positioning structure when inserted into a circuit board or substrate, making it prone to deviations, positional shifts, and loosening during the insertion process.

[0006] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0007] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a 20P connector structure. Through the design of the extension portion, the connecting sections of the second terminal group are all located within the extension portion. In this way, the connecting sections of the second terminal group are hidden within the extension portion, avoiding the exposure of the connecting sections of the second terminal group outside the plastic base, thereby protecting the connecting sections of the second terminal group. Secondly, the design of several raised portions ensures that each contact portion is subjected to force synchronously during insertion and removal, avoiding poor contact caused by height differences and ensuring stable signal and power transmission. Finally, the design of the extension portion, by acting as a pin support structure for the connector, significantly enhances the overall mechanical strength of the connector and stabilizes the connector position when inserted into a circuit board or substrate.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A 20P connector structure includes a plastic base, a first terminal group, and a second terminal group. Both the first terminal group and the second terminal group include a contact section, a connecting section, and a soldering section connected sequentially from top to bottom. The plastic base includes a main body, which includes a front sidewall, a left sidewall, a rear sidewall, and a right sidewall connected to each other. The front sidewall, left sidewall, rear sidewall, and right sidewall form a placement cavity.

[0010] A plurality of raised portions are provided on the left side wall, rear side wall and right side wall, and the raised portions extend from one side of the corresponding side wall toward the placement cavity; at least a portion of the first terminal group is provided on the raised portion, and the welding section of the first terminal group extends outward from the lower end of the connecting section to the outside of the raised portion, so that the contact section of the first terminal group is flush with the contact section of the second terminal group.

[0011] An extension portion is provided on the front sidewall, the connecting sections of the second terminal group are all located within the extension portion, and the welding sections of the second terminal group all extend outward from the lower end of the connecting section to the outside of the plastic base.

[0012] An extension portion is provided on the side of the rear sidewall away from the placement cavity. The lower end of the extension portion is provided with a plug-in portion for subsequent plug-in connection and positioning with external products. The plug-in portion extends beyond the lower end of each welding segment. The plug-in portion includes a main body and several vertical portions extending from one end of the main body. Adjacent vertical portions form a mating groove.

[0013] As a preferred embodiment, the lower ends of the plurality of vertical portions are provided with guide slopes to facilitate subsequent plug-in and plug-out connections.

[0014] As a preferred embodiment, the connecting section of the first terminal group is provided with outwardly extending first extension arms on both sides. The outer end of the first extension arm extends downward to form a first mating arm to form a first fixing arm. The plastic base is provided with a first fixing groove corresponding to the first fixing arm. The first terminal group is inserted into the plastic base so that the first fixing arm fits into the first fixing groove, thereby improving the structural strength of the terminal in the plastic base and preventing the terminal from loosening when the connector is pulled or used for a long time. This ensures the stability of the product, with a clever and reasonable structural design, long service life, good practicality, and wide applicability.

[0015] As a preferred embodiment, the connecting section of the second terminal group is provided with outwardly extending second extension arms on both sides. The outer end of the second extension arm extends downward to form a second mating arm to form a second fixing arm. A second fixing groove is provided in the plastic base corresponding to the second fixing arm. The second terminal group is inserted into the plastic base so that the second fixing arm fits into the second fixing groove, thereby improving the structural strength of the terminal in the plastic base and preventing the terminal from loosening when the connector is pulled or used for a long time. This ensures the stability of the product, with a clever and reasonable structural design, long service life, good practicality, and wide applicability.

[0016] As a preferred embodiment, the diameter of the first fixing groove is larger than the diameter of the first fixing arm to allow for assembly clearance and compensate for machining tolerances.

[0017] As a preferred embodiment, the diameter of the second fixing groove is larger than the diameter of the second fixing arm to allow for assembly clearance and compensate for machining tolerances.

[0018] As a preferred embodiment, the raised portion is further provided with a reinforcing rib on the side near the extension portion. The reinforcing rib includes a connecting portion and a supporting portion. The connecting portion extends upward from the upper edge of the front end of the raised portion, and the supporting portion is connected to the rear end of the connecting portion and the upper end surface of the raised portion, respectively.

[0019] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly achieves this through the design of the extension portion. An extension portion is provided on the front side wall of the plastic base, and the connecting sections of the second terminal group are all located inside the extension portion. In this way, the connecting sections of the second terminal group can be hidden inside the extension portion, avoiding the connecting sections of the second terminal group being exposed outside the plastic base. This can protect the connecting sections of the second terminal group and effectively isolate the first terminal group and the second terminal group, avoiding signal crosstalk and short circuits.

[0020] Secondly, there is the design of several raised parts, which extend from one side of the corresponding sidewall toward the placement cavity; at least part of the first terminal group is disposed on the raised parts, so that the contact section of the first terminal group is flush with the contact section of the second terminal group. In this way, when plugging and unplugging, each contact part is subjected to force synchronously, avoiding poor contact caused by height difference and ensuring stable signal and power transmission.

[0021] The design of the extension section includes a plug-in portion extending from the lower end of the extension section. The plug-in portion extends beyond the lower end of each soldering section. This extension section serves as a pin support structure for the connector, significantly enhancing the overall mechanical strength of the connector. When inserted into a circuit board or substrate, it can stabilize the connector position, effectively resist the effects of insertion and extraction forces and equipment vibration, prevent the connector from loosening or deforming, ensure long-term reliable connection, and assist the soldering portion in accurately inserting into the substrate pad holes or corresponding slots (in conjunction with the plug-in portion), improving the insertion positioning accuracy.

[0045] A 20P connector structure includes a plastic base 1, a first terminal group 2, and a second terminal group 3.

[0046] The first terminal group 2 and the second terminal group 3 each include a contact section 21, a connecting section 22, and a welding section 23 connected sequentially from top to bottom; the plastic base 1 includes a main body 11, which includes a front side wall 111, a left side wall 112, a rear side wall 113, and a right side wall 114 connected to each other, and the front side wall 111, the left side wall 112, the rear side wall 113, and the right side wall 114 form a placement cavity 115; a plurality of raised portions 12 are extended on the left side wall 112, the rear side wall 113, and the right side wall 114, and the plurality of raised portions 12 extend from one side of the corresponding side wall toward the placement cavity 115; at least a portion of the first terminal group 2 is disposed on the raised portion 12, and the welding section 23 of the first terminal group 2 extends outward from the lower end of the connecting section 22 to the outside of the raised portion 12, so that the contact section 21 of the first terminal group 2 is flush with the contact section 21 of the second terminal group 3;

[0047] Preferably, the raised portion 12 is further provided with a reinforcing rib 13 on the side near the extension portion 15. The reinforcing rib 13 includes a connecting portion 131 and a supporting portion 132. The connecting portion 131 extends upward from the upper edge of the front end of the raised portion 12, and the supporting portion 132 is connected to the rear end of the connecting portion 131 and the upper end surface of the raised portion 12 respectively.

[0048] An extension portion 14 extends from the front sidewall 111. The connecting sections 22 of the second terminal group 3 are all located within the extension portion 14. The welding sections 23 of the second terminal group 3 extend outward from the lower end of the connecting section 22 to the outside of the plastic base 1. A shielding portion (not shown in the figure) may also be provided at the plurality of raised portions 12. The connecting portion 131 of the first terminal group 2 is located within the shielding portion, thereby protecting the connecting portion 131 of the second terminal group 3.

[0049] An extension portion 15 extends from the side of the rear sidewall 113 away from the placement cavity 115. The lower end of the extension portion 15 extends to form a plug-in portion 151 for subsequent insertion and connection with external products. The plug-in portion 151 extends beyond the lower ends of each welding segment 23. The plug-in portion 151 includes a main body portion 1511 and several vertical portions 1512 extending from one end of the main body portion 1511. Adjacent vertical portions 1512 form a mating groove 1513. Preferably, the lower ends of the several vertical portions 1512 are provided with guide slopes to facilitate subsequent insertion and connection.

[0050] Preferably, the connecting section 22 of the first terminal group 2 is provided with outwardly extending first extension arms 24 on both sides. The outer end of the first extension arms 24 extends downward to form a first mating arm 25 to form a first fixing arm 26. The plastic base 1 is provided with a first fixing groove 16 corresponding to the first fixing arm 26. The first terminal group 2 is inserted into the plastic base 1 so that the first fixing arm 26 is adapted to the first fixing groove 16, thereby improving the structural strength of the terminal in the plastic base 1 and avoiding the terminal loosening phenomenon when the connector is pulled or used for a long time. This ensures the stability of the product, with a clever and reasonable structural design, long service life, good practicality, and wide applicability.

[0051] Preferably, the diameter of the first fixing groove 16 is larger than the diameter of the first fixing arm 26, leaving an assembly gap and compensating for machining tolerances.

[0052] Preferably, the connecting section 22 of the second terminal group 3 is provided with outwardly extending second extension arms 31 on both sides. The outer end of the second extension arm 31 extends downward to form a second mating arm 32 to form a second fixing arm 33. The plastic base 1 is provided with a second fixing groove 17 corresponding to the second fixing arm 33. The second terminal group 3 is inserted into the plastic base 1 so that the second fixing arm 33 fits into the second fixing groove 17, thereby improving the structural strength of the terminal in the plastic base 1. This avoids the terminal from becoming loose when the connector is pulled or used for a long time, ensuring the stability of the product. The structure is ingenious and reasonable, with a long service life, good practicality, and wide applicability.

[0053] Preferably, the diameter of the second fixing groove 17 is larger than the diameter of the second fixing arm 33, leaving an assembly gap and compensating for machining tolerances. In this embodiment, when the first terminal group 2 and the second terminal group 3 are inserted and removed from the plastic base 1, they are both straight-line terminals. After the first terminal group 2 and the second terminal group 3 are inserted and removed from bottom to top, they are bent by a tooling fixture. The reverse insertion and removal design of the first terminal group 2 and the second terminal group 3 means that the contact section 21 of each terminal is first passed through the bottom of the plastic base 1. Since the depth of the fixing groove is greater than the size of the fixing arm, there will be no interference during the installation process, thus affecting the assembly.

[0054] The key design feature of this utility model is that it is mainly achieved through the design of the extension portion. An extension portion is provided on the front side wall of the plastic base, and the connecting sections of the second terminal group are all located inside the extension portion. In this way, the connecting sections of the second terminal group can be hidden inside the extension portion, avoiding the connecting sections of the second terminal group being exposed outside the plastic base. This can protect the connecting sections of the second terminal group and effectively isolate the first terminal group and the second terminal group, avoiding signal crosstalk and short circuits.

[0055] Secondly, there is the design of several raised parts, which extend from one side of the corresponding sidewall toward the placement cavity; at least part of the first terminal group is disposed on the raised parts, so that the contact section of the first terminal group is flush with the contact section of the second terminal group. In this way, when plugging and unplugging, each contact part is subjected to force synchronously, avoiding poor contact caused by height difference and ensuring stable signal and power transmission.

[0056] The design of the extension section includes a plug-in portion extending from the lower end of the extension section. The plug-in portion extends beyond the lower end of each soldering section. This extension section serves as a pin support structure for the connector, significantly enhancing the overall mechanical strength of the connector. When inserted into a circuit board or substrate, it can stabilize the connector position, effectively resist the effects of insertion and extraction forces and equipment vibration, prevent the connector from loosening or deforming, ensure long-term reliable connection, and assist the soldering portion in accurately inserting into the substrate pad holes or corresponding slots (in conjunction with the plug-in portion), improving the insertion positioning accuracy.

[0057] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
