DETAILED DESCRIPTION

[0035] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0036] In order to solve the problems existing in the prior art such as inconvenient wire connection, low strength of connecting springs, insufficient convenience of plugging and the like, the present invention provides a plug-in connection terminal with a female end spring clip of higher strength and a positional relationship that is more conducive to plugging, so as to achieve a more stable plugging effect and connection performance.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the plug-in connection terminal described in the present invention includes a male terminal connector 1 and a female terminal connector 2 that are plugged into each other, a male terminal spring piece 10 is arranged in the male terminal connector 1, and a female terminal spring piece 20 is arranged in the female terminal connector 2, the wires at both ends are respectively fixed to the male terminal connector 1 and the female terminal connector 2, and the male terminal connector 1 and the female terminal connector 2 are plugged in, so that the male terminal spring piece 10 is in contact with the female terminal spring piece 20, thereby realizing conductive connection between the wires at both ends.

[0038] like Fig. 9 , Fig.10 As shown, the male end spring piece 10 includes a male end wiring portion 101 and a male end connecting portion 102. The male end connecting portion 102 includes a flat surface at the front section and an arched surface 1021 at the end; Fig.12 , Fig.13 As shown, the female end spring piece 20 includes a female end wiring portion 201 and a female end connecting portion 202, and the female end connecting portion 202 is a straight flat plate; Figure 6 As shown, when the male terminal connector 1 and the female terminal connector 2 are plugged in, in a state where the female end connection part 202 is not in contact with the male end connection part 102, the end of the female end connection part 202 is biased toward the bottom surface of the arched surface 1021 and is displaced in height with the end of the arched surface 1021, and then the plugging continues, the female end connection part 202 presses against and squeezes the arched surface 1021, forcing the arched surface 1021 to shift in position, thereby driving the male end connection part 102 to undergo elastic deformation, and the female end connection part 202 enters the bottom surface position of the arched surface 1021. Under the elastic resetting action of the male end connection part 102, the female end connection part 202 is tightly against the bottom surface of the arched surface 1021 connected to the male end connection part 102, as shown in FIG. Figure 7 As shown, it is ensured that the male terminal connector 1 and the female terminal connector 2 are conductive.

[0039] like Figure 3 , Figure 4 , Figure 5As shown, the male terminal connector 1 includes a male terminal socket 11 and a plug-in pin 12, and the female terminal connector 2 includes a female terminal socket 21 and a plug-in socket 22; the female end connecting portion 202 of the female end spring clip 20 is arranged in the plug-in socket 22, and the male end connecting portion 102 of the male end spring clip 10 corresponds to the female end connecting portion 202 and is arranged in the plug-in pin 12.

[0040] Since the common incoming and outgoing lines are two-phase incoming and outgoing lines or three-phase incoming and outgoing lines, the corresponding male terminal connector 1 includes a plurality of plug-in pins 12 arranged horizontally, such as two plug-in pins 12, or three plug-in pins 12, and the male terminal connector 11 corresponds to the male terminal spring piece 10, that is, corresponds to the plug-in pin 12, and sets mutually separated male terminal connector slots 111. This embodiment takes the two-phase incoming and outgoing lines as an example, that is, the male terminal connector 1 is provided with two plug-in pins 12 and two male terminal connector slots 111.

[0041] In order to facilitate quick assembly and prevent short circuit caused by reverse connection, an anti-fool mechanism is provided between the socket 22 and the plug-in pin 12 to ensure that the socket 22 and the plug-in pin 12 are only allowed to be plugged in one direction. In this embodiment, the anti-fool mechanism includes an anti-fool rib 221 protruding inward from the inner wall of the socket 22, and an anti-fool groove 122 on the plug-in pin 12 corresponding to the anti-fool rib 221. That is, the top surface of each plug-in pin 12 is provided with an anti-fool groove 122 along the length direction, and the top and bottom surfaces between adjacent plug-in pins 12 are provided with anti-fool grooves 122 along the length direction; the anti-fool rib 221 is provided corresponding to the anti-fool groove 122. Among them, the anti-fool groove 122 arranged on the bottom surface is wider than the anti-fool groove 122 arranged on the top surface. Since the number and position of the fool-proofing grooves 122 and fool-proofing ribs 221 on the top and bottom surfaces are different, plugging can only be performed in the correct direction; otherwise, the fool-proofing grooves 122 and fool-proofing ribs 221 will not match each other and will cause jamming, making plugging impossible.

[0042] Furthermore, the foolproof mechanism also includes round chamfers 222 on both sides of the bottom surface of the socket 22, and clearance grooves 123 on both sides of the bottom surface of the plug-in pin 12 corresponding to the round chamfers 222. That is, the inner contour of the socket 22 is a "D"-shaped cross section; correspondingly, in order to smoothly plug in, the two sides of the bottom surface of the plug-in pin 12 are provided with clearance grooves 123 corresponding to the round chamfers 222, and then the plug-in pin 12 is formed as a whole to form a "D"-shaped cross section to adapt to the foolproof structure of the socket 22.

[0043] Corresponding to the foolproof mechanism, the plug-in pin 12 is provided with a "convex" channel 121 along the length direction, which is used to accommodate the male end connection part 102; wherein the narrow end of the "convex" channel 121 faces the bottom surface of the plug-in pin 12, and the wide end of the "convex" channel 121 faces the top surface of the plug-in pin 12. In addition, the wide end of the "convex" channel 121 is provided with a foolproof groove 122, and the width of the wide end of the "convex" channel 121 can be adapted to the width setting of the male end connection part 102.

[0044] The male terminal connection seat 11 corresponds to the male terminal spring clip 10, and is provided with mutually separated male terminal connection slots 111, which are communicated with the corresponding plug-in tube pin 12. The male terminal spring clip 10 is inserted from the male terminal connection slot 111 and penetrates the "convex" channel 121 of the plug-in tube pin 12. In order to limit the installation of the male terminal spring clip 10, a male "convex" groove 1111 is provided in the male terminal connection slot 111 along the length direction, such as Figure 6 , Figure 7 As shown, a sunken step 112 is formed between the male end "convex" groove 1111 and the plug-in pin 12; in this embodiment, the "convex" channel 121 of the plug-in pin 12 is misaligned in height with the male end wiring groove 111, thereby forming the step 112. The outer contour of the narrow end of the "convex" channel 121 protrudes from the plug-in pin 12, and the foolproof groove 122 opened on the bottom surface of the plug-in pin 12 is formed by the interval between the outer contours of the narrow ends of the parallel "convex" channel 121. Fig. 9 , Fig.10 As shown, the male end connection part 102 extends a male end limiting wing 1023 toward both sides from one end of the male end wiring part 101, and a male end elastic buckle 1022 with a protrusion is provided toward the bottom surface. The male end limiting wing 1023 and the male end elastic buckle 1022 are arranged in the male end "convex" groove 1111 corresponding to the outline of the male end "convex" groove 1111. In this embodiment, the male end "convex" groove 1111 is surrounded by ribs extending laterally from the inner walls on both sides of the male end wiring groove 111, and the groove on the bottom surface. During assembly, the male end limiting wing 1023 is located in the wide end of the male end "convex" groove 1111 to form upper and lower limits, and the narrow end of the male end "convex" groove 1111 is used to form a certain space for the male end elastic buckle 1022 to make way for the male end spring piece 10 to slide smoothly and easily into the male end "convex" groove 1111. During the assembly process, when the male elastic buckle 1022 passes over the step 112, it elastically resets, that is, it unfolds to a natural state, forming a reverse limit with the step 112 to prevent the male spring piece 10 from detaching in the opposite direction of the sliding installation.

[0045] Similar to the principle of the male terminal connector 1, the female terminal connection seat 21 corresponds to the female terminal spring clip 20, and is provided with mutually separated female terminal connection slots 211, which are communicated with the plug seat 22, and the female terminal spring clip 20 is inserted from the female terminal connection slot 211 and penetrated into the plug seat 22. In order to separate the female terminal spring clips 20, the anti-foolproof ribs 221 corresponding to the anti-foolproof slots 122 between adjacent plug-in pins 12 extend inwardly longer than the anti-foolproof ribs 221 corresponding to the anti-foolproof slots 122 of the plug-in pins 12. In this way, the anti-foolproof function is realized, and it can also be used to isolate adjacent female terminal spring clips 20.

[0046] In order to limit the installation of the female end spring piece 20, a female end "convex" groove 2111 is provided in the female end wiring groove 211 along the length direction, such as Figure 6 , Figure 7 As shown, the female end "convex" groove 2111 is provided with a sinking card platform 212 at one end facing the plug socket 22; Fig.12 , Fig.13 As shown, the female end connection part 202 extends female end limiting wings 2022 toward both sides from one end of the female end wiring part 201, and a raised female end elastic buckle 2021 is provided toward the bottom surface. The female end limiting wings 2022 and the female end elastic buckle 2021 are arranged in the female end "convex" groove 2111 corresponding to the contour of the female end "convex" groove 2111. In this embodiment, the structure of the female end "convex" groove 2111 is the same as the male end "convex" groove 1111, and the principle and function are also the same, and thus the installation process of the female end spring clip 20 is also the same. During assembly, the female end elastic buckle 2021 elastically resets after passing over the clamping platform 212, unfolds to a natural state, and forms a reverse limit with the clamping platform 212.

[0047] like Figure 8 As shown, the outer contour of the male terminal wiring slot 111 protrudes from the male terminal wiring seat 11 and extends toward the plug-in pin 12, and a male terminal wiring blind hole 1112 is formed in the male terminal wiring slot 111 for plugging in the wire; the male terminal wiring portion 101 is bent toward the male terminal wiring blind hole 1112 for contacting and connecting with the wire. In this embodiment, the male terminal wiring portion 101 and the male terminal connecting portion 102 are bent to form an acute angle, that is, the end of the male terminal wiring portion 101 faces the male terminal wiring blind hole 1112, so when the wire is inserted, the male terminal wiring portion 101 forms an inclined surface to facilitate easy insertion of the wire, and forms a top resistance to the withdrawal of the wire from the opposite direction, thereby ensuring the connection strength of the wire and realizing screw-free installation.

[0048] Same as male terminal connector 1, such as Fig.11As shown, the outer contour of the female terminal wiring slot 211 protrudes from the female terminal wiring seat 21 and extends toward the plug seat 22, and a female terminal wiring blind hole 2112 is formed in the female terminal wiring slot 211 for plugging in the wire; the female terminal wiring part 201 is bent toward the direction of the female terminal wiring blind hole 2112 for contacting and connecting with the wire and realizing screw-free installation of the wire.

[0049] At the same time, if Figure 1 As shown, the outer contour of the male terminal blind hole 1112 forms a limit block 113. When plugged in place, the end face of the socket 22 abuts against the limit block 113. In order to ensure the connection strength between the male terminal connector 1 and the female terminal connector 2, raised clamping blocks 13 are provided on both sides of the male terminal connector 1, and the plug-in pin 12 is interference-fitted with the socket 22 through the clamping blocks 13.

[0050] The above embodiments are only used to illustrate the present invention, and are not used to limit the present invention. As long as they are based on the technical essence of the present invention, changes and modifications to the above embodiments will fall within the scope of the claims of the present invention.
