Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connection terminal capable of being plugged in at multiple angles. Background Art

[0002] The connection terminal is arranged in the high-voltage connector, and the high-voltage current is mainly passed smoothly through the internal contact finger structure. The existing high-voltage connectors are mainly divided into two types, one is a 180° plug-in high-voltage connector as disclosed in announcement number CN308674557S, and the other is a 90° plug-in high-voltage connector as disclosed in announcement number CN308674558S. Correspondingly, different matching connection terminals need to be arranged inside the high-voltage connectors with different plug-in methods. The existing connection terminals are also mainly divided into two types, such as the 90° plug-in disclosed in announcement number CN110277679A, or the 180° plug-in disclosed in announcement number CN 213184724 U.

[0003] Conventional high-voltage connectors are internally provided with matching connection terminals. The incompatibility between the 90° connection terminals and the 180° connection terminals requires the preparation of at least two types of connection terminals for plug-in methods, which invisibly increases the manufacturing cost and is not conducive to cost control and processing and assembly.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Moreover, in the description of the scheme, with the operator as a reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0026] like Figures 1 to 5 As shown, the utility model discloses a connection terminal that can be plugged in at multiple angles, including a connection shell 1 and two springs 2. The interior of the connection shell 1 is hollow, and a first card slot 101 and a second card slot 102 are formed at two ends thereof. The opening direction of the first card slot 101 is perpendicular to the opening direction of the second card slot 102. The first card slot 101 and the second card slot 102 are respectively provided with a spring 2 to form a first plug interface and a second plug interface with perpendicular opening directions, respectively.

[0027] In this solution, a first card slot 101 and a second card slot 102 with opening directions perpendicular to each other are formed at both ends of the connection shell 1 to respectively clamp the spring 2 to form a first plug interface and a second plug interface with plugging directions perpendicular to each other, so that one connection terminal can simultaneously meet the different requirements of 90° plugging and 180° plugging.

[0028] Specifically, the connecting shell 1 includes a first plate 103 and a second plate 104 with the same structure and arranged opposite to each other. A connecting plate 105 is provided between the two sides of the first plate 103 and the second plate 104, so that the first plate 103 and the second plate 104 form the first card slot 101 and the second card slot 102 at both ends. The connecting shell 1 is preferably formed by folding and stamping an integral plate to facilitate manufacturing and enhance the integrity of the device. The first card slot 101 and the second card slot 102 are preferably limit slots with openings on three sides. In another feasible embodiment, the first card slot 101 and / or the second card slot 102 can be limit slots with openings on two sides to allow the spring 2 to be inserted respectively.

[0029] Similarly, the spring sheet 2 is an integrated component, which includes a middle portion 201 and elastic contact portions 202 symmetrically arranged on both sides of the middle portion 201. The spring sheet 2 is folded so that the two elastic contact portions 202 are opposite to each other up and down, and the elastic contact portions 202 abut against the inner walls of the first plate body 103 and the second plate body 104 to form the inner surfaces of the first plug interface and the second plug interface.

[0030] Specific as Figure 1 and Figure 2 As shown, the middle part 201 is connected to the elastic contact part 202 via a connecting part 203, and the connecting part 203 is provided with two elastic blocks 204 that tilt outward, and the first plate 103 and the second plate 104 are provided with a bayonet 106 that matches the elastic blocks 204, and the elastic blocks 204 are inserted into the bayonet 106 to limit the position of the spring 2 and prevent it from moving. Such a structure makes it unnecessary to set up other fixing structures in the first slot 101 and the second slot 102, and the limiting structure is formed by the structure of the first slot 101 and the second slot 102, so as to facilitate assembly and save costs.

[0031] Furthermore, a group of limit blocks 109 are respectively arranged on both sides of the inner wall of the first card slot 101 and the second card slot 102, and a group of limit blocks 109 constitute a limit portion adapted to the outer contour of the spring 2. A group of limit blocks 109 has a limiting effect on the position of the spring 2 to prevent it from moving at will, and at the same time, a group of limit blocks 109 also has a guiding effect on the insertion of the spring 2, and a group of limit blocks 109 are relatively arranged to limit the insertion direction of the spring 2.

[0032] In order to further enhance the connection stability between the spring 2 and the first and second slots 101 and 102, the extended end of the spring 2 has a limiting structure that is engaged with the ends of the first and second plates 103 and 104. Specifically, the extended end of the spring 2 has at least two feasible forms.

[0033] like Figure 2 , Figure 3 , Figure 4 As shown, a first embodiment of the spring leaf 2 is shown. In the first embodiment, the extending end of the elastic contact portion 202 has a strip-shaped first abutment portion 205, and the ends of the first plate body 103 and the second plate body 104 are provided with a first limiting recess 107. The first abutment portion 205 is perpendicular to the extension direction of the elastic contact portion 202 and is clamped in the first limiting recess 107.

[0034] like Figure 1 , Figure 5 As shown, a second embodiment of the spring leaf 2 is shown. In the second embodiment, the extending end of the elastic contact portion 202 has a hook-shaped second abutment portion 206, and the opening ends of the first plate body 103 and the second plate body 104 are provided with a second limiting recess 108, and the second abutment portion 206 is snap-connected with the second limiting recess 108.

[0035] The spring piece 2 is further cooperated with the elastic block 204 through the structure of the first abutting portion 205 being engaged with the first limiting recess 107 or the second abutting portion 206 being engaged with the second limiting recess 108, to jointly limit the position of the spring piece 2, thereby ensuring that it maintains a stable position during use, thereby ensuring the effectiveness of the connection.

[0036] Furthermore, the elastic contact portion 202 includes fixed ribs 2021 and elastic ribs 2022 that are arranged at intervals and staggered. Both ends of the fixed ribs 2021 are fixedly connected to the body of the reed 2 and are bent in an M shape. One end of the elastic rib 2022 is fixedly connected to the body of the reed 2 and is bent in an arc shape. The bending points of the fixed ribs 2021 and the elastic ribs 2022 are their contact points, and the contact points of the fixed ribs 2021 and the elastic ribs 2022 are staggered to increase the contact points when the elastic contact portion 202 is plugged in with other connectors (such as copper busbars), thereby increasing the contact area and contact effectiveness.

[0037] The back of the bending point of the elastic rib 2022 is provided with a convex block 2023 to enhance the strength of the bending point of the elastic rib 2022 so that it will not be bent in the reverse direction. Preferably, the convex block 2023 is formed by a concave arrangement of the body of the elastic rib 2022.

[0038] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0039] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
