DETAILED DESCRIPTION

[0030] The embodiments of the present invention provide a multi-contact point high-reliability connector terminal and an electrical connector, which are used to solve the technical problem that in the prior art, the electrical connection between plugs is generally achieved by connecting electrode terminals, and the connection of electrode terminals is mainly achieved by coaxial connection. This connection method has poor overcurrent capability and low stability. At the same time, it is necessary to distinguish between male and female heads, which is inconvenient to use.

[0031] The overall idea of the technical solution provided by the present invention is as follows:

[0032] The multi-contact point high-reliability connector terminal comprises: a first connection terminal 100, a first end of the first connection terminal 100 is provided with a first elastic clamping portion 110, and a first connection portion 120 is provided between the second end of the first connection terminal 100 and the first elastic clamping portion 110; a second connection terminal 200, a first end of the second connection terminal 200 is provided with a second elastic clamping portion 210, and a second connection portion 220 is provided between the second end of the second connection terminal 200 and the second elastic clamping portion 210; wherein the first elastic clamping portion 110 is used to clamp the second connection portion 220, and the second elastic clamping portion 210 is used to clamp the first connection portion 120, and both the first connection terminal 100 and the second connection terminal 200 have a connection portion and an elastic clamping portion, that is, the shapes of the first connection terminal 100 and the second connection terminal 200 can be consistent, thereby achieving the effect of not distinguishing between male and female terminals, That is, the terminals are used without distinguishing between positive and negative poles and are non-polar terminals. The first connection terminal 100 and the second connection terminal 200 are arranged oppositely in the vertical direction. Specifically, the positions of the first elastic clamping part 110 and the first connection part 120 of the first connection terminal 100 in the vertical direction are opposite to the positions of the second elastic clamping part 210 and the second connection part 220 of the second connection terminal 200 in the vertical direction. Then the first connection terminal 100 and the second connection terminal 200 are continuously approached to each other, and finally the first elastic clamping part 110 clamps the second connection part 220, and the second elastic clamping part 210 clamps the first connection part 120 to achieve the connection between the first connection terminal 100 and the second connection terminal 200. This connection method enables the two electrode terminals to have at least two pairs of contact points, which is stronger in current carrying capacity and higher in stability than the traditional method of only one pair of contact points.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figure 1 and Figure 3 , both the first connecting portion 120 and the second connecting portion 220 include at least one protruding inserting piece structure 500, and the inserting piece structure 500 is used to enter the first elastic clamping portion 110 or the second elastic clamping portion 210 so as to be clamped by the first elastic clamping portion 110 or the second elastic clamping portion 210.

[0035] Preferably, the inserting piece structure 500 is an arc structure. Because in actual use, the first connecting terminal 100 and the second connecting terminal 200 approach and connect to each other along the circumferential direction, in order to make the connection smoother, the inserting piece structure 500 is set as an arc, so that during the rotational connection process of the first connecting terminal 100 and the second connecting terminal 200, the inserting piece structure 500 can more conveniently enter the first elastic clamping portion 110 or the second elastic clamping portion 210 and be clamped.

[0036] Further, please refer to Figure 1 , a first limiting portion 600 is provided between the first elastic clamping portion 110 and the first connecting portion 120, and a second limiting portion 700 is provided between the second elastic clamping portion 210 and the second connecting portion 220. The first limiting portion 600 and the second limiting portion 700 are used to limit the axial movement of the inserting piece structure 500 when the first connecting terminal 100 and the second connecting terminal 200 are connected. In one implementation, after the first connecting terminal 100 and the second connecting terminal 200 are connected, the first elastic clamping portion 110 will clamp the second connecting portion 220, and the second elastic clamping portion 210 will clamp the first connecting portion 120. If there is no first limiting portion 600 and second limiting portion 700, when pulling the first connecting terminal 100 or the second connecting terminal 200 along the axis, the two will separate from each other, resulting in the problem of unstable connection between the first connecting terminal 100 and the second connecting terminal 200. After setting the first limiting portion 600 and the second limiting portion 700, when pulling the first connecting terminal 100 or the second connecting terminal 200 along the axis, the inserting piece structure 500 will be resisted by the first limiting portion 600 or the second limiting portion 700, thereby preventing the first connecting terminal 100 and the second connecting terminal 200 from disengaging along the axis, and making their connection more stable even when they form an interlock.

[0037] In another implementation, please refer toFigure 9 The first limiting portion 600 and the second limiting portion 700 are both arranged in a Z shape. When the two are close to each other and connected, the axial movement will be locked. When the first connecting terminal 100 and the second connecting terminal 200 are connected, the first limiting portion 600 is connected to the second limiting portion 700. When the first connecting terminal 100 or the second connecting terminal 200 is pulled axially, the first limiting portion 600 and the second limiting portion 700 will lock each other, thereby preventing the first connecting terminal 100 and the second connecting terminal 200 from detaching along the axial direction.

[0038] Specifically, the first limiting portion 600 and the second limiting portion 700 may be inclined surfaces or horizontal surfaces perpendicular to the axial direction.

[0039] See also Figure 4 and Figure 5 The first connection terminal 100 and the second connection terminal 200 each include: at least one pair of elastic sheets 300 spaced apart from each other, the first ends of the at least one pair of elastic sheets 300 are combined with each other to form the first elastic clamping portion 110 or the second elastic clamping portion 210, and the second ends of the at least one pair of elastic sheets 300 are relatively fixed. For example, the first connection terminal 100 and the second connection terminal 200 each include a pair of elastic sheets 300. Since the second ends of the pair of elastic sheets 300 are relatively fixed, when the connecting portion stretches the first ends of the pair of elastic sheets 300, it will be clamped by the first ends of the pair of elastic sheets 300, thereby playing a role of elastic clamping. More specifically, the first ends of the pair of elastic sheets 300 relatively form a guide portion that is gradually narrowed from wide, so that the connecting portion can enter between the first ends of the pair of elastic sheets 300 more easily.

[0040] See also Figure 3 The first elastic clamping portion 110 and the second elastic clamping portion 210 each include at least one clamping portion 400. More specifically, the clamping portion 400 is provided with a guide opening 410 which is gradually narrowed from wide to narrow. The connecting portion enters the clamping portion 400 from the guide opening 410 and is clamped by the clamping portion 400. The guide opening 410 which is gradually narrowed from wide to narrow makes it easier for the external connecting portion to enter the clamping portion 400. The number of the clamping portions 400 may be multiple, such as Figure 1 and Figure 3 As shown, three clamping parts 400 are provided. The more the number of the clamping parts 400 is, the more contact points there are between the first connection terminal 100 and the second connection terminal 200, so that the overcurrent capacity after the two terminals are connected is stronger.

[0041] Preferably, the number of the first connection terminals 100 and the second connection terminals 200 may also be multiple, wherein the number of the first connection terminals 100 should match the number of the second connection terminals 200, such as Figure 2As shown, there are three first connection terminals 100 and also three second connection terminals 200. Optionally, the number of first connection terminals 100 and the number of second connection terminals 200 can match the number of wires.

[0042] An embodiment of the present invention also provides an electrical connector, including a multi-contact high-reliability connector terminal as in the foregoing embodiment. The various change modes and specific embodiments in the foregoing embodiment are equally applicable to the electrical connector in this embodiment. Through the detailed description of the multi-contact high-reliability connector terminal above, those skilled in the art can clearly know the implementation method of the electrical connector in this embodiment. For the sake of simplicity of the specification, it will not be elaborated here.

[0043] Further, please refer to Figures 6 to 8 , the electrical connector includes a plug 800 and a socket 900. The first connection terminal 100 is disposed in the plug 800, and the second connection terminal 200 is disposed in the socket 900. The plug 800 is used to be inserted into the socket 900 and rotate to connect the first connection terminal 100 and the second connection terminal 200. Specifically, compared with the coaxial connection method of terminals in the prior art, in this embodiment, the first connection terminal 100 and the second connection terminal 200 are connected by rotating the plug 800 and the socket 900, that is, the first elastic clamping portion 110 clamps the second connection portion 220, and the second elastic clamping portion 210 clamps the first connection portion 120. Such a connection method enables at least two pairs of contact points between the two electrode terminals, compared with only one pair of contact points in the traditional coaxial connection. This connection method realizes multi-point connection, making the current-carrying capacity stronger and the stability higher after the first connection terminal 100 and the second connection terminal 200 are connected. It can be understood that multiple first connection terminals 100 can be disposed in the plug 800, and multiple second connection terminals 200 can be disposed in the socket 900 to match the number of wires in the cable.

[0044] Specifically, please refer to Figures 6 to 8, the plug 800 and the socket 900 are connected by the cooperation of the boss 910 and the locking groove 810. For example, the boss 910 is provided on the inner side wall of the socket 900, and the locking groove 810 is provided on the outer side wall of the plug 800. Insert the plug 800 into the socket 900, the boss 910 enters the locking groove 810, and rotate the plug 800 so that the boss 910 is locked by the locking groove 810, thereby completing the connection between the plug 800 and the socket 900. More specifically, the locking groove 810 may include a communicating guiding groove and a locking groove, wherein the locking groove is horizontally arranged. The boss 910 enters the locking groove from the guiding groove, and then rotates the boss 910 to rotate into the locking groove and be locked. Through the connection structure of the cooperation between the boss 910 and the locking groove 810, the locking force is strong and the locking process is short. Only a little rotation process is required to lock, and it does not need to rotate many circles like a threaded connection. It can be understood that when the plug 800 and the socket 900 are rotationally fixed, the first connection terminal 100 and the second connection terminal 200 are connected, that is, the first elastic clamping portion 110 clamps the second connection portion 220, and the second elastic clamping portion 210 clamps the first connection portion 120.

[0045] In summary, one or more of the above technical solutions in the embodiments of the present application have at least one or more of the following technical effects:

[0046] In a multi-contact high-reliability connector terminal and an electrical connector provided in an embodiment of the present invention, the multi-contact high-reliability connector terminal includes: a first connection terminal 100, a first elastic clamping portion 110 is provided at the first end of the first connection terminal 100, and a first connection portion 120 is provided between the second end of the first connection terminal 100 and the first elastic clamping portion 110; a second connection terminal 200, a second elastic clamping portion 210 is provided at the first end of the second connection terminal 200, and a second connection portion 220 is provided between the second end of the second connection terminal 200 and the second elastic clamping portion 210; wherein, the first elastic clamping portion 110 is used to clamp the second connection portion 220, the second elastic clamping portion 210 is used to clamp the first connection portion 120, and both the first connection terminal 100 and the second connection terminal 200 have a connection portion and an elastic clamping portion, that is, the shapes of the first connection terminal 100 and the second connection terminal 200 can be the same, so as to achieve the effect of not distinguishing between male and female terminals, that is, the terminals can be used without distinguishing between anode and cathode, belonging to non-polar terminals. The first connection terminal 100 and the second connection terminal 200 are arranged in opposite directions along the vertical direction, and then the first connection terminal 100 and the second connection terminal 200 are continuously close to each other, and finally the first elastic clamping portion 110 clamps the second connection portion 220, and the second elastic clamping portion 210 clamps the first connection portion 120 to realize the connection between the first connection terminal 100 and the second connection terminal 200. Such a connection method enables the two electrode terminals to have at least two pairs of contact points, which has a stronger current-carrying capacity and higher stability than the traditional one with only one pair of contact points in contact.
