[0003] At present, the means of electrical connection between the wire and the terminal block mainly adopt welding and plug-in. Welding requires the use of welding technology, which is not only complicated to operate, but also inconvenient to operate due to the space limitation of the device, and welding is also inconvenient to disassemble and install later; plug-in mainly realizes the fixation of the wire and the terminal block by setting a locking structure, and the need to set an additional locking structure makes the overall structure complicated. Due to the setting of the locking structure, the current plug-in terminal block is a one-way plug-in structure. Therefore, the wire needs to be plugged into the terminal block in a specific direction for conductivity, and the terminal block has limitations in use, which makes it inconvenient to use.

[0004] As can be seen from the above, the current wiring terminals have a complex structure and limitations in use, which leads to inconvenience in use. Utility Model Content

[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0034] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0035] In order to solve the problem that the connection terminal in the prior art has a complex structure and has limitations in use, which leads to inconvenience in use, the utility model provides a connection terminal. In this embodiment, the connection terminal is arranged on a substrate for achieving electrical conduction.

[0036] Embodiment 1

[0037] like Figures 1 to 8 As shown, the terminal block 20 includes a shell and an elastic arm 40, and through holes are respectively provided on two parallel plate segments on the shell. The two through holes cooperate to form a plug-in channel for the conductive member 10 to pass through. The first end of the elastic arm 40 is provided on at least one of the two plate segments, and the second end of the elastic arm 40 is bent toward the inside of the shell and at least a portion extends into the inside of the plug-in channel. The second end of the elastic arm 40 can clamp the conductive member 10 inside the plug-in channel through elastic deformation.

[0038] Among them, the elastic arm 40 is a structure that can undergo elastic deformation. When the conductive part 10 extends into the interior of the plug-in channel, it will abut the second end of the elastic arm 40 to drive the elastic arm 40 to undergo elastic deformation. At the same time, the second end of the elastic arm 40 is offset under the elastic deformation to avoid the conductive part 10. At the same time, the second end of the elastic arm 40 abuts on the conductive part 10 to fix the conductive part 10.

[0039] In this embodiment, the elastic arms 40 are arranged in pairs, and the two elastic arms 40 arranged in pairs are arranged on the same plate segment at intervals along the length direction of the plate segment. The two elastic arms 40 are bent toward the inside of the shell and extend in directions facing each other. An elastically deformable clamping gap 50 is formed between the ends of the two elastic arms 40 facing each other. The clamping gap 50 and the through holes on the two plate segments form a plug-in channel. The clamping gap 50 clamps the conductive part 10 through elastic deformation.

[0040] Specifically, the terminal block 20 used in the present application is provided with a pair of elastic arms 40 on at least one of the two parallel plate sections on the housing, so that the two elastic arms 40 can clamp and abut the conductive member 10 passing through the clamping gap 50 through the feature that the elastic arms 40 can undergo elastic deformation, thereby fixing the conductive member 10 and improving the stability of conduction. The pair of elastic arms 40 used in the present application cooperates with the conductive member 10 to clamp and fix the conductive member 10, wherein the restoring force of the elastic arms 40 provides the clamping force for clamping the conductive member 10, and there is no need to provide an additional locking structure. The conductive member 10 itself is a part of the fixing structure, and the overall structure is simple and easy to operate.

[0041] The clamping gap 50 becomes larger and elastically deformed as the conductive member 10 passes through the clamping gap 50 due to the elastic deformation of the elastic arm 40 .

[0042] It is understandable that after the elastic arm 40 undergoes elastic deformation, the elastic arm 40 has a restoring force to restore the original position. The restoring force of the elastic arm 40 of the present application provides a clamping force for clamping the conductive member 10. Under the action of the clamping force, the elastic arm 40 and the conductive member 10 are engaged and fixed with each other. When the conductive member 10 is subjected to a force and tends to retreat, the clamping gap 50 tends to shrink. At this time, the force of the elastic arm 40 clamping the conductive member 10 becomes larger, and the bite force between the elastic arm 40 and the conductive member 10 becomes larger, thereby improving the stability of the clamping, so as to achieve the phenomenon that the conductive member 10 will not retreat and fall off.

[0043] It should be noted that the elastic arms 40 are not limited to being arranged in pairs. The elastic arm 40 may be only one of the two arranged in a pair. It is also possible to clamp the conductive member 10 by deforming a single elastic arm 40 .

[0044] like Figure 2 The X direction shown is the length direction of the plate segment, such as Figure 2 The Y direction shown is the width direction of the plate segment, such as Figure 2 The Z direction shown is the height direction of the connection terminal 20 .

[0045] Furthermore, the elastic arm 40 and the housing are integrally formed, which is conducive to increasing the stability of the connection between the elastic arm 40 and the housing. Of course, the elastic arm 40 and the housing can also be welded and fixed, which is based on the ability to achieve a stable arrangement of the elastic arm 40 on the housing.

[0046] Furthermore, the specific size of the clamping gap 50 is not greater than the diameter of the conductive member 10. When the conductive member 10 passes through the clamping gap 50, the conductive member 10 pushes the elastic arm 40 to undergo elastic deformation, and then the elastic arm 40 abuts against the outer surface of the conductive member 10 to achieve fixed clamping.

[0047] In this embodiment, the conductive member 10 is a wire or other electronic component having a wire, and one end of the conductive member 10 that is plugged into the wiring terminal 20 is the connecting end 11 , and the connecting end 11 is electrically connected to the wiring terminal 20 .

[0048] Before the connection terminal 20 of this embodiment is used, the distance of the clamping gap 50 formed between the two elastic arms 40 is Figure 4 As shown in A, during the use of the wiring terminal 20 of this embodiment, when it needs to cooperate with the conductive member 10, the wiring terminal 20 is directly inserted through the via hole. After passing through the via hole, the conductive member 10 drives the elastic arm 40 to elastically deform, even if the clamping gap 50 is elastically deformed, the distance of the clamping gap 50 is Figure 4 As shown in B, the size of B is larger than the size of A, and the clamping gap 50 becomes larger, making it easier for the elastic arm 40 to clamp and fix the conductive member 10.

[0049] In this embodiment, the elastic arm 40 includes at least a clamping arm section 410, and one end of the clamping arm section 410 facing each other is a clamping end, and the two clamping ends form a clamping gap 50. When the conductive member 10 passes through the clamping gap 50, the conductive member 10 provides a driving force for the two clamping ends to elastically deform toward the side away from each other, and the two clamping ends abut against the outer surface of the conductive member 10. The extension direction of the clamping arm section 410 is set at an angle to the extension direction of the conductive member 10.

[0050] The clamping end is the second end of the elastic arm 40 and is used to clamp the conductive member 10. When the terminal block 20 is matched with the conductive member 10, after the conductive member 10 passes through the through hole on one of the plate segments, the conductive member 10 drives the clamping ends of the two elastic arms 40 to deviate toward one side of the other plate segment. At this time, the clamping gap 50 becomes larger to allow the conductive member 10 to pass through, and the clamping end abuts against the outer surface of the conductive member 10 to clamp the conductive member 10. Since the clamping arm segment 410 undergoes elastic deformation under the drive of the conductive member 10, the extension direction of the elastically deformed clamping arm segment 410 is set at an angle to the conductive member 10, thereby enhancing the stability of the elastic arm 40 clamping the conductive member 10.

[0051] In this embodiment, the following two implementation modes are provided according to the different structures of the elastic arm 40 .

[0052] like Figure 8 In the specific embodiment shown, the elastic arm 40 includes and only includes a clamping arm segment 410, that is, the elastic arm 40 is a clamping arm segment 410, at which time the first end of the clamping arm segment 410 is connected to the plate segment, and the second end of the clamping arm segment 410 extends in a direction at an angle to the length direction of the plate segment.

[0053] like Figures 2 to 4 In the specific embodiment shown, the elastic arm 40 also includes a bending arm segment 420, one end of the bending arm segment 420 is connected to the plate segment, and the other end of the bending arm segment 420 is bent and connected to the clamping arm segment 410, and the clamping arm segment 410 is arranged parallel to or at an angle to the plate segment.

[0054] Among them, the bending arm section 420 is used to form a bend toward the inner side of the shell, and the clamping arm section 410 is arranged on the bending arm section 420. The extension direction of the clamping arm section 410 can be parallel to the length direction of the plate section, or the extension direction of the clamping arm section 410 can be parallel to the extension direction of the plate section, so as to form a clamping gap 50 between the clamping ends of the two elastic arms 40.

[0055] In this embodiment, the bent arm segment 420 is an arc-shaped arm segment.

[0056] In this embodiment, the two elastic arms 40 arranged in pairs are symmetrically arranged about the via hole, so that the two elastic arms 40 clamp the conductive member 10 with the same force, which is beneficial to improving the stability of the elastic arms 40 clamping the conductive member 10.

[0057] In this embodiment, two elastic arms 40 arranged in pairs form an elastic arm group, and one or more elastic arm groups are provided. When one elastic arm group is provided, the elastic arm group is provided on one of the two plate segments; when multiple elastic arm groups are provided, the multiple elastic arm groups are arranged at intervals along the length direction of the plate segment, and the multiple elastic arm groups are provided on the same plate segment or are respectively provided on two plate segments.

[0058] Specifically, an elastic arm 40 segment is used to clamp a conductive member 10. According to the number of matches between the conductive member 10 and the terminal block 20, the elastic arm 40 segment can be adaptively set as needed, and one or more elastic arm 40 segments can be set on each plate segment along the length direction of the plate segment.

[0059] Furthermore, a plurality of elastic arm groups are provided on one plate segment, so that a plurality of conductive members 10 can be electrically connected to the connection terminals 20 on the same side.

[0060] Furthermore, elastic arm groups are respectively arranged on the two plate sections, so that a plurality of conductive members 10 arranged on opposite sides can be electrically connected to the wiring terminals 20 .

[0061] like Figures 2 to 4 As shown, the housing of this embodiment includes a top plate segment 21 and a bottom plate segment 22, and the top plate segment 21 and the bottom plate segment 22 are arranged in parallel. One of the two parallel plate segments is the top plate segment 21 and the other is the bottom plate segment 22. Two elastic arms 40 arranged in pairs are respectively arranged at both ends of the length direction of the top plate segment 21 or the bottom plate segment 22. Vias are respectively provided on the top plate segment 21 and the bottom plate segment 22, and the vias are used for the conductive member 10 to pass through.

[0062] Specifically, via holes are provided on the top plate segment 21 and the bottom plate segment 22 to enable the conductive member 10 to be inserted into the connecting terminal 20 up and down along the height direction of the connecting terminal 20 .

[0063] It should be noted that the through holes on the top plate segment 21 and the bottom plate segment 22 can be insertion holes or avoidance holes.

[0064] In one specific implementation of this embodiment, the elastic arm 40 is disposed on the top plate segment 21 .

[0065] When the conductive part 10 extends through the through hole on the top plate section 21, the conductive part 10 extending into the interior of the outer shell drives the clamping end of the clamping arm section 410 of the elastic arm 40 to move toward the side of the bottom plate section 22, so that the clamping arm section 410 and the conductive part 10 are set at an angle, thereby achieving the conductive part 10 being clamped by the elastic arm 40.

[0066] Furthermore, when the conductive part 10 extends through the through hole on the bottom plate section 22, the conductive part 10 extending into the interior of the housing drives the clamping end of the clamping arm section 410 of the elastic arm 40 to move toward the top plate section 21, so that the clamping arm section 410 and the conductive part 10 are set at an angle, thereby achieving the conductive part 10 being clamped by the elastic arm 40.

[0067] The elastic arm 40 of the present embodiment can undergo elastic deformation in both directions, which facilitates the insertion of the conductive member 10 on both sides, and is beneficial to improving the application range of the connecting terminal 20 and increasing the diversity of usage scenarios.

[0068] Preferably, two elastic arms 40 are arranged in pairs and are respectively arranged at two ends of the top plate section 21 in the length direction.

[0069] In another specific implementation of this embodiment, the elastic arm 40 is disposed on the bottom plate segment 22 .

[0070] When the conductive part 10 extends through the through hole on the top plate section 21, the conductive part 10 extending into the interior of the outer shell drives the clamping end of the clamping arm section 410 of the elastic arm 40 to move toward the side of the bottom plate section 22, so that the clamping arm section 410 and the conductive part 10 are set at an angle, thereby achieving the conductive part 10 being clamped by the elastic arm 40.

[0071] Furthermore, when the conductive part 10 extends through the through hole on the bottom plate section 22, the conductive part 10 extending into the interior of the housing drives the clamping end of the clamping arm section 410 of the elastic arm 40 to move toward the top plate section 21, so that the clamping arm section 410 and the conductive part 10 are set at an angle, thereby achieving the conductive part 10 being clamped by the elastic arm 40.

[0072] The elastic arm 40 of the present embodiment can undergo elastic deformation in both directions, which facilitates the insertion of the conductive member 10 on both sides, and is beneficial to improving the application range of the connecting terminal 20 and increasing the diversity of usage scenarios.

[0073] The two elastic arms 40 are preferably arranged in pairs and are respectively arranged at two ends of the bottom plate section 22 in the length direction.

[0074] In this embodiment, the housing further includes a connecting plate segment 23 disposed between the top plate segment 21 and the bottom plate segment 22 . The connecting plate segment 23 is used to support the top plate segment 21 and the bottom plate segment 22 , thereby improving the strength of the housing.

[0075] In this embodiment, the bottom plate section 22 has a protruding structure 221 bent toward the side away from the top plate section 21 , and the side of the protruding structure 221 away from the top plate section 21 is used to connect with the base plate 30 , wherein the protruding structure 221 is fixed to the base plate 30 by welding.

[0076] Embodiment 2

[0077] Different from the first embodiment, Figures 5 to 8 As shown, in this embodiment, one of the two plate segments arranged in parallel is the first side plate segment 24 and the other is the second side plate segment 25 .

[0078] Specifically, the via holes of the present application are arranged on the first side plate segment 24 and the second side plate segment 25 , so that the conductive member 10 is electrically connected to the connection terminal 20 through the via holes on the first side plate segment 24 and the second side plate segment 25 .

[0079] Furthermore, when multiple elastic arm groups are provided on one of the first side panel segment 24 and the second side panel segment 25, multiple conductive members 10 on a single side can be electrically connected to the connecting terminal 20; when elastic arm groups are provided on both the first side panel segment 24 and the second side panel segment 25, conductive members 10 on both sides can be electrically connected to the connecting terminal 20.

[0080] In a specific implementation of the present embodiment, two elastic arms 40 arranged in pairs are provided on the first side panel segment 24 and the second side panel segment 25. Along the length direction of the panel segment, the elastic arms 40 arranged on the first side panel segment 24 are spaced apart from the elastic arms 40 arranged on the second side panel segment 25.

[0081] It should be noted that the elastic arms 40 are arranged at intervals in the length direction of the plate segment to achieve interference after the wall elastic arms 40 undergo elastic deformation.

[0082] Further, when a group of two elastic arms 40 arranged in pairs are provided on the first side panel segment 24 and the second side panel segment 25, the first side panel segment 24 has two through holes arranged at intervals along the length direction, one of which is the insertion hole of the first side panel segment 24, and the other is a avoidance hole corresponding to the insertion hole on the second side panel segment 25; similarly, the second side panel segment 25 has two through holes arranged at intervals along the length direction, one of which is the insertion hole of the second side panel segment 25, and the other is a avoidance hole corresponding to the insertion hole on the first side panel segment 24.

[0083] In this embodiment, the housing further includes a top plate 26 and a bottom plate 27. The top plate 26, the first side plate segment 24, the bottom plate 27 and the second side plate segment 25 form a housing. The bottom plate 27 has a connecting portion 271 extending toward a side away from the top plate 26. The side of the connecting portion 271 away from the top plate 26 is used to connect with the base plate 30. The top plate 26 and the bottom plate 27 are used to support and fix the housing to improve the strength of the housing. The connecting portion 271 is fixed to the base plate 30 by welding.
