Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and in particular relates to a signal transmission connector. Background Art

[0002] As a circuit transmission device, connectors are widely used in various electronic products. Connectors include wire-to-wire connectors, wire-to-board connectors, and board-to-board connectors. Among them, some connectors use the combination of jack terminals and pin terminals to achieve current or signal transmission. During the use of connectors, when in a vibrating environment, the connection between the jack terminal and the jack socket, or the pin terminal and the pin socket is prone to loosening, and the jack terminal and the pin terminal are also prone to popping off, which cannot ensure stable contact, seriously affecting the normal use of the connector.

[0003] In the prior art, the position of the jack terminal is fixed by installing a TPA component on the jack socket. Although this solves the connection stability problem between the jack terminal and the jack socket to a certain extent, the contact stability problem between the jack terminal and the pin terminal is still not well solved. Utility Model Content

[0012] A second elastic arm structure is formed on the inner wall of the socket housing at the installation position corresponding to each of the pin terminals along the installation direction of the pin terminals, and a second limit structure engaged with the second elastic arm structure is formed on the pin terminals. The second elastic arm structure further limits the movement of the pin terminals in the installation direction, making it difficult for the pin terminals to fall out in a vibration environment, and further improving the connection stability.

DETAILED DESCRIPTION

[0036] 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.

[0037] 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.

[0038] Example 1

[0039] refer to Figures 1 to 5 The signal transmission connector provided by the utility model includes a plug end 1 and a socket end 2 for plug-in connection. The plug end 1 includes a plug housing 11, a plurality of socket terminals 12 installed inside the plug housing 11, and a plug end TPA component 13 for locking and fixing the plurality of socket terminals 12. The socket end 2 includes a socket housing 21, a plurality of pin terminals 22 installed inside the socket housing 21, and a socket end TPA component 23 for locking and fixing the plurality of pin terminals 22.

[0040] A contact spring 121 for electrically connecting to the pin terminal 22 is provided inside the socket terminal 12. The contact spring 121 is arranged along the length direction of the socket terminal 12, and the end away from the pin terminal 22 is fixedly connected to the inner wall of the socket terminal 12, and the end close to the pin terminal 22 is suspended. When the pin terminal 22 is inserted into the socket terminal 12, the suspended end of the contact spring 121 will abut against the surface of the pin terminal 22, thereby achieving electrical connection between the socket terminal 12 and the pin terminal 22. Since the contact portion of the contact spring 121 and the pin terminal 22 generates a positive elastic force under the abutment of the pin terminal 22, stable contact can be achieved.

[0041] Furthermore, the jack terminal 12 is also formed with a reinforcing sheet 122, which abuts against the elastic arm of the contact spring sheet 121 to strengthen the positive elastic force of the contact spring sheet 121. In some embodiments, the reinforcing sheet 122 is formed by bending the side wall of the jack terminal 12. The reinforcing sheet 122 abuts against the contact spring sheet 121, limiting the reverse deformation of the contact spring sheet 121, thereby enhancing the positive elastic force of the contact spring sheet 121 and further improving the contact stability between the contact spring sheet 121 and the pin terminal 22. In some embodiments, an observation hole can also be opened on the side wall of the jack terminal 12 to observe the contact state between the contact spring sheet 121 and the pin terminal 22.

[0042] As a further optimization, a first convex bump 123 is provided on the contact portion between the contact spring 121 and the pin terminal 22, and a second convex bump 124 for contacting the pin terminal 22 is provided on the inner side wall of the socket terminal 12 facing the contact spring 121. It should be noted that the suspended end of the contact spring 121 will bend toward the inner side wall of the socket terminal 12, and when the pin terminal 22 is inserted into the socket terminal 12, the pin terminal 22 is located between the contact spring 121 and the inner side wall of the socket terminal 12 facing the contact spring 121.

[0043] As one implementation method, a first convex bump 123 is provided on the contact spring 121, and two second convex bumps 124 are provided on the inner wall of the socket terminal 12. The first convex bump 123 and the second convex bump 124 are provided. On the one hand, the contact points between the socket terminal 12 and the pin terminal 22 are increased, which can improve the signal transmission rate between the terminals; on the other hand, the positive force between the socket terminal 12 and the pin terminal 22 is increased, making the electrical connection more stable.

[0044] As one embodiment, a plurality of jack terminals 12 are arranged in two rows at equal intervals, a first installation groove 111 for the plug-end TPA component 13 to be engaged is provided in the plug housing 11 along the arrangement direction of the jack terminals 12, a first boss 131 is provided on the plug-end TPA component 13 at a position corresponding to each jack terminal 12, and a first limiting groove 125 matching the first boss 131 is provided on the jack terminal 12. Each pin terminal 22 is electrically connected to a corresponding jack terminal 12, a second installation groove 211 for the socket-end TPA component 23 to be engaged is provided in the socket housing 21 along the arrangement direction of the pin terminals 22, a second boss 231 is provided on the socket-end TPA component 23 at a position corresponding to each pin terminal 22, and a second limiting groove 221 matching the second boss 231 is provided on the pin terminal 22.

[0045] In some embodiments, mounting buckles are provided at both ends of the plug-end TPA component 13, and mounting grooves for the mounting buckles to engage are provided at corresponding positions on the two side walls of the plug housing 11; a convex buckle is provided on the top surface of the plug-end TPA component 13, and a groove for the convex buckle to engage is provided at corresponding positions of the plug housing 11. During installation, the plug-end TPA component 13 first enters a pre-installed state, at which time the convex buckle abuts against the surface of the plug housing 11 to limit the position of the plug-end TPA component 13; then the jack terminals 12 are installed one by one into the plug housing 11, at which time the first boss 131 is located above the first limiting groove 125; then the plug-end TPA component 13 is pressed to make the convex buckle engage in the groove and the mounting buckle engage in the mounting groove, completing the installation of the plug-end TPA component 13, at which time the first boss 131 engages in the first limiting groove 125 to achieve locking and fixing of the jack terminal. The structure and installation principle of the socket-end TPA component 23 are the same as those of the plug-end TPA component 13.

[0046] By engaging the first boss 131 with the first limiting groove 125, each socket terminal 12 is locked in position in the horizontal and vertical directions; by engaging the second boss 231 with the second limiting groove 221, each pin terminal 22 is locked in position in the horizontal and vertical directions, thereby improving the connection stability of the connector.

[0047] In some embodiments, a first elastic arm structure 112 is formed on the inner wall of the plug housing 11 at a mounting position corresponding to each socket terminal 12 along the mounting direction of the socket terminal 12, and a first limiting structure 126 engaged with the first elastic arm structure 112 is formed on the socket terminal 12. A second elastic arm structure 212 is formed on the inner wall of the socket housing 21 at a mounting position corresponding to each pin terminal 22 along the mounting direction of the pin terminal 22, and a second limiting structure 222 engaged with the second elastic arm structure 212 is formed on the pin terminal 22.

[0048] In some embodiments, the plug housing 11 is a plastic shell, and a mounting cavity is formed inside the plug housing 11 corresponding to the mounting position of each jack terminal 12. The first elastic arm structure 112 is formed by extending from the inner wall of the mounting cavity toward the mounting direction of the jack terminal 12, and the fixed end of the first elastic arm structure 112 is away from the pin terminal 22, and the elastic end is close to the pin terminal 22. When the jack terminal 12 is installed in the corresponding mounting cavity, the first limiting structure 126 first passes through the fixed end of the first elastic arm structure 112, and then presses against the elastic end of the first elastic arm structure 112 to deform it. When the first limiting structure 126 leaves the first elastic arm structure 112, the elastic end of the first elastic arm structure 112 rebounds under the action of the elastic force and is engaged with the end of the first limiting structure 126, thereby fixing the jack terminal 12. The first elastic arm structure 112 further limits the movement of the jack terminal 12 in the installation direction, making it difficult for the jack terminal 12 to fall out in a vibration environment, and further improving the connection stability between the jack terminal 12 and the plug housing 11. The structure and fixing principle of the second elastic arm structure 212 are similar to those of the first elastic arm structure 112, so they will not be described in detail.

[0049] As a further optimization, the minimum distance d1 between two adjacent jack terminals 12 is 0.45±0.05mm, preferably 0.45mm. The minimum distance d2 between the jack terminal 12 and the outer wall of the socket housing 21 is 5.87±0.5mm, preferably 5.87mm. The minimum distance between the jack terminals 12 meets the withstand voltage requirement of 1000VAC in the IEC60664-1 standard, and the minimum distance between the jack terminal 12 and the outer wall of the socket housing 21 meets the withstand voltage requirement of 6000VAC in the IEC60664-1 standard, thereby achieving the high-voltage resistance of the signal transmission connector.

It should be noted that a spring structure is formed on the outer wall of the plug housing 11, one end of the spring structure is fixedly connected to the outer wall of the plug housing 11, and the other end is in a suspended state, and the elastic hook 113 is located on the spring structure. During installation, the fixed end of the spring structure first enters the interior of the socket housing 21, and then the elastic hook 113 is engaged and locked with the slot 213 to complete the installation. At this time, the suspended end of the spring structure is located outside the socket housing 21; during disassembly, the elastic hook 113 can be released from the slot 213 by pressing the suspended end of the spring structure, and the loading and unloading process is convenient and efficient.

[0052] In some embodiments, the angle between the elastic hook 113 and the spring structure is less than 90 degrees, preferably 85 degrees, so as to improve the fastening of the elastic hook 113 and the slot 213, and further improve the connection stability between the plug housing 11 and the socket housing 21. In some embodiments, the elastic hook 113 is arranged on a side away from the first mounting slot 111.

[0053] As a further optimization, a foolproof guide groove 214 is provided on the inner side wall of the socket housing 21 along the insertion direction of the plug housing 11, and a foolproof convex strip 114 matching the foolproof guide groove 214 is provided on the corresponding position of the outer side wall of the plug housing 11. In some embodiments, the number of foolproof guide grooves 214 is set according to actual needs, and the number of foolproof convex strips 114 matches the number of foolproof guide grooves 214. Preferably, four foolproof guide grooves 214 are provided. With the cooperation of the foolproof guide grooves 214 and the foolproof convex strips 114, the plug end 1 and the socket end 2 can be installed in alignment, effectively preventing the damage of the jack terminal 12 or the pin terminal 22 caused by mis-insertion during insertion.
