[0042] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0043] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0044] Example 1

[0045] refer to Figures 1 to 5 The relay adapter connector provided in this embodiment includes a first housing 11, a mounting seat 12 and a transfer terminal 13. The mounting seat 12 is disposed in the first housing 11, and the transfer terminals 13 are arranged in two rows at equal intervals and mounted on the mounting seat 12. In some embodiments, the first housing 11 and the mounting seat 12 can be an integrated molding structure.

[0046] The first housing 11 includes a first end 111 and a second end 112, and the adapter terminal 13 includes a cable terminal 131 and a pin terminal 132 for plugging and connecting. The cable terminal 131 faces the first end 111 and is used to electrically connect with the cable connector; the pin terminal 132 faces the second end 112 and is used to electrically connect with the cable connector. It can be understood that the relay adapter connector 1 is connected to the cable connector and the cable connector through the first end 111 and the second end 112, respectively, and the cable connector and the relay adapter connector 1, and the cable connector and the relay adapter connector 1 are all detachably connected, thereby allowing the free combination and installation of cable connectors of different specifications and cable connectors of different specifications, and the assembly flexibility is strong.

[0047] The plug-in connected flat cable terminal 131 and the pin terminal 132 are used as transfer terminals to connect the flat cable connector and the cable connector respectively. Users can replace the flat cable terminal 131 or the pin terminal 132 of different shapes and sizes according to different usage needs, so as to meet diverse usage needs and have strong versatility. In some embodiments, the flat cable terminal 131 has a double-arm double-contact structure, thereby enhancing contact reliability and improving connection stability.

[0048] As a further optimization, the end where the cable terminal 131 is connected to the pin terminal 132 is provided with a first fork tine 133, and the end where the pin terminal 132 is connected to the cable terminal 131 is formed with a second fork tine 134, and the first fork tine 133 and the second fork tine 134 are plugged and connected with each other. It can be understood that the first fork tine 133 and the second fork tine 134 each have two fork claws, and when the first fork tine 133 and the second fork tine 134 are plugged, the two fork claws of the first fork tine 133 respectively abut the opposite sides of the body of the second fork tine 134, and the two fork claws of the second fork tine 134 respectively abut the opposite sides of the body of the first fork tine 133. In this way, a stable connection between the cable terminal 131 and the pin terminal 132 is achieved, which is conducive to ensuring the stability of signal transmission.

[0049] As a further optimization, a first contact 135 is formed on the first fork tine 133 at a contact position corresponding to the pin terminal 132, and a second contact 136 is formed on the second fork tine 134 at a contact position corresponding to the cable terminal 131. As one embodiment, there are two first contacts 135, which are respectively located at the ends of the two fork claws of the first fork tine 133 and facing each other; there are two second contacts 136, which are respectively located at the ends of the two fork claws of the second fork tine 134 and facing each other. The cable terminal 131 and the pin terminal 132 are electrically contacted through the first contact 135 and the second contact 136, which reduces the contact area, increases the contact pressure, effectively improves the contact stability between the cable terminal 131 and the pin terminal 132, and has strong contact reliability.

[0050] In some embodiments, the thickness of the cable terminal 131 is different from the thickness of the pin terminal 132. Preferably, the thickness of the cable terminal 131 is less than the thickness of the pin terminal 132. Since the cable terminal 131 is electrically connected to the cable connector, and the cable connector usually electrically contacts the cable terminal 131 through the contact strip on the cable, reducing the thickness of the cable terminal 131 is conducive to increasing the contact pressure and improving the reliability and stability of the contact; the pin terminal 132 is electrically connected to the cable connector, and the cable connector usually electrically contacts the pin terminal 132 through the jack terminal. Increasing the thickness of the pin terminal 132 can increase the contact area and ensure transmission efficiency and connection stability. As one embodiment, the thickness of the cable terminal 131 is 0.2mm, and the thickness of the pin terminal 132 is 0.4-0.5mm.

[0051] The relay adapter connector of this embodiment connects the cable connector and the cable connector respectively through the first end and the second end, has high flexibility and is easy to combine and install; the cable terminal and the pin terminal of plug-in connection are used as the adapter terminal, and the cable terminal and the pin terminal of different shapes and sizes can be replaced according to different usage requirements, and it has strong versatility; the connection between the cable terminal and the pin terminal is achieved by the cross-matching of the first fork tine and the second fork tine, and the connection method is stable and reliable, which is conducive to ensuring the stability of signal transmission; the electrical contact between the cable terminal and the pin terminal is achieved by setting the first contact point and the second contact, and the contact stability and reliability are strong; by setting the cable terminal and the pin terminal to different thicknesses, different contact performance requirements can be met, thereby improving the contact reliability and stability of the connector and ensuring the transmission efficiency of the connector.

[0052] Example 2

[0053] As a further optimization of Example 1, Figures 1 to 5 Based on the reference Figures 6 to 11A limiting protrusion 137 for limiting the installation depth of the cable terminal 131 is formed on one side of the cable terminal 131, and a limiting groove 121 matching the limiting protrusion 137 is formed on the installation position of the cable terminal 131 corresponding to the mounting seat 12. The limiting protrusion 137 is located at one end of the cable terminal 131 close to the first fork 133, and the limiting protrusion 137 protrudes from the side wall of the cable terminal 131 in a direction perpendicular to the side wall. When the cable terminal 131 is inserted into the mounting seat 12, the limiting protrusion 137 abuts against the inner wall of the limiting groove 121 to limit the cable terminal 131, preventing the cable terminal 131 from being inserted too much and affecting the normal and stable electrical connection between the cable terminal 131 and the cable connector. At the same time, it can also ensure the consistency of the insertion depth of each cable terminal 131, thereby improving product quality.

[0054] The mounting base 12 is formed with a plurality of bosses 122 toward the second end 112, and each boss 122 is located between two adjacent pin terminals 132. It can be understood that the pin terminals 132 are arranged in two rows at equal intervals, and a boss 122 is provided between two adjacent pin terminals 132 in each row of pin terminals 132. Providing a boss 122 between two adjacent pin terminals 132 can increase the creepage distance between the two pin terminals 132, thereby improving the electrical performance of the connector.

[0055] In some embodiments, a snap connection position 113 and a screw connection position 114 are provided on the outside of the first housing 11. As one embodiment, the snap connection position 113 and the screw connection position 114 are respectively provided on different sides of the first housing 11. Providing both the snap connection position 113 and the screw connection position 114 on the first housing 11 can realize different installation and fixing methods to meet different installation and fixing requirements of users.

[0056] The relay adapter connector of this embodiment effectively avoids over-insertion of the cable terminals by providing a limiting protrusion, while ensuring the consistency of the insertion depth of the cable terminals; by providing a boss, the creepage distance between the pin terminals is increased, thereby improving the electrical performance of the product; by providing both a snap connection position and a screw connection position on the first shell, it can meet the different installation and fixing requirements of users and has strong versatility.

[0060] The cable connector 3 includes a third shell 31 and a jack terminal 32 installed in the third shell 31 . The jack terminals 32 are arranged in two rows at equal intervals. The head of the jack terminal 32 is electrically connected to the pin terminal 132 , and the tail of the jack terminal 32 is riveted with a cable 33 .

[0061] The cable connector 2 is also provided with an FPA component 24 for locking and fixing the cable 22. The FPA component 24 is connected to the second housing 21 and abuts against the cable 22. The FPA component 24 can improve the connection stability between the cable 22 and the second housing 21, thereby ensuring the contact stability between the cable 22 and the cable terminal 131, which is beneficial to improving the overall connection stability of the connector.

[0062] The cable connector 3 is also provided with a TPA member 34 for locking and fixing the socket terminal 32. The TPA member 34 is engaged and connected to the third housing 31 and abuts against the socket terminal 32. The TPA member 34 improves the connection stability between the socket terminal 32 and the third housing 31, and can maintain the electrical contact stability between the socket terminal 32 and the pin terminal 132, thereby further improving the overall connection stability of the connector.

[0063] An elastic snap-fit ​​structure 211 is provided on the outside of the second housing 21, and a hook 115 is formed inside the first housing 11 to snap-fit ​​with the elastic snap-fit ​​structure 211. The elastic snap-fit ​​structure 211 can be inserted into the first housing 11 by the first housing 11 pressing and deforming the elastic snap-fit ​​structure 211, and then the elastic snap-fit ​​structure 211 is released to make it rebound naturally and reset, thereby realizing snap-fit ​​connection with the hook 115.
