[0001] This utility model relates to the field of electrical component technology, and in particular to a high-voltage connector terminal fixing structure and a high-voltage connector. Background Technology

[0002] High-voltage connectors play a crucial role as key components in the field of new energy electric vehicles. Existing high-voltage connector terminals have the following shortcomings: 1. The connection between the terminal and the housing is not stable enough; 2. The heat dissipation space of the terminal is insufficient, which causes the high-voltage connector to be in a high-temperature state for a long time, affecting its service life.

[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0004] The purpose of this utility model is to provide a high-voltage connector terminal fixing structure, which has the advantages of stable and robust structure and good heat dissipation.

[0005] Another objective of this utility model is to provide a high-voltage connector, which includes the above-mentioned high-voltage connector terminal fixing structure, and has the advantages of stable and robust structure and good heat dissipation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-voltage connector terminal fixing structure includes a housing and a terminal; the housing has a slot for inserting the terminal, and the inner walls on both sides of the slot have inwardly recessed portions, the inner walls of the recesses have hanging tongues, and the ends of the hanging tongues are located outside the recesses; the outer walls on both sides of the terminal have positioning holes corresponding to the ends of the hanging tongues.

[0008] According to one embodiment of the present invention, the top of the hanging tongue is provided with an upwardly protruding ear plate.

[0009] According to one embodiment of the present invention, the hanging tongue extends along the insertion direction of the terminal, so that the two hanging tongues are in a figure-eight shape.

[0010] According to one embodiment of the present invention, the housing is cylindrical, and a first opening and a second opening are respectively provided at both ends of the housing, the first opening and the second opening being arranged along the insertion direction of the terminal.

[0011] According to one embodiment of the present invention, the opening directions of the first opening and the second opening are perpendicular to each other.

[0012] According to one embodiment of the present invention, the terminal is provided with a plurality of plug tabs, the plug tabs corresponding to the second opening.

[0013] According to one embodiment of the present invention, the slot is provided with a limiting ridge at one end near the second opening, and the terminal is provided with a limiting groove corresponding to the limiting ridge.

[0014] According to one embodiment of the present invention, the end of the terminal near the first opening is connected to a cable.

[0015] According to one embodiment of the present invention, there is an installation space between the cable and the housing, and the cross-section of the installation space gradually increases in the direction from the second opening to the first opening.

[0016] This utility model also provides a high-voltage connector, including the above-mentioned high-voltage connector terminal fixing structure.

[0017] Compared with the prior art, the advantages and beneficial effects of the embodiments of this utility model are as follows:

[0018] The high-voltage connector terminal fixing structure and high-voltage connector provided in this embodiment of the invention feature a terminal that, when inserted into the slot of the housing, has elastic tabs on both sides of the slot that remain in contact with the outer wall of the terminal under the action of elasticity until the terminal is fully inserted. At this point, the ends of the tabs then fall into the positioning holes on both sides of the terminal under the action of elasticity, thus securing the terminal firmly. Since both ends of the terminal are fixedly connected to the positioning holes via tabs, the pull-out force of the terminal is increased, greatly improving the stability of the terminal fixation. Furthermore, the recessed portions formed on the inner walls of the slots on both sides of the terminal create a larger heat dissipation space on both sides of the terminal, which is beneficial for heat dissipation during operation, reducing the terminal's operating temperature and extending its service life.

[0029] like Figures 1-5As shown, this embodiment of the utility model provides a high-voltage connector terminal fixing structure, including a housing 1 and a terminal 2. The housing 1 has a slot 11 for inserting the terminal 2. Both sides of the inner wall of the slot 11 have inwardly recessed portions 12. The inner wall of each recess 12 has a hanging tongue 13, the end of which is located outside the recess 12. Both sides of the outer wall of the terminal 2 have positioning holes 21 corresponding to the ends of the hanging tongues 13.

[0030] The high-voltage connector terminal fixing structure provided in this embodiment of the utility model has the following characteristics: When the terminal 2 is inserted into the slot 11 of the housing 1, the hanging tongues 13 on both sides of the slot 11 are elastic and always abut against the outer wall of the terminal 2 under the action of elasticity until the terminal 2 is fully inserted. Then, the ends of the hanging tongues 13 fall into the positioning holes 21 on both sides of the terminal 2 under the action of elasticity, thus fixing the terminal 2 securely. Since both ends of the terminal 2 are fixedly connected to the positioning holes 21 through the hanging tongues 13, the pull-out force of the terminal 2 is increased, greatly improving the stability of the terminal 2. In addition, since the inner walls of the slots 11 on both sides of the terminal 2 have recessed portions 12, a larger heat dissipation space is formed on both sides of the terminal 2, which is beneficial for heat dissipation during operation, reducing the operating temperature of the terminal 2 and extending its service life.

[0031] like Figure 1 , Figure 3 , Figure 4 As shown, in order to facilitate the removal of terminal 2, in one embodiment of this utility model, the top of the hanging tongue 13 is provided with an upwardly protruding ear plate 14. When it is necessary to remove terminal 2, the ear plate 14 can be manually or with a tool pushed away from the positioning hole 21 to remove terminal 2. The removal process is simple and efficient.

[0032] To facilitate the insertion of terminal 2 into housing 1, such as Figures 1-3 As shown, in one embodiment of this utility model, the latch 13 extends along the insertion direction of the terminal 2, so that the two latches 13 are in a figure-eight shape. This allows the two latches 13 to be easily pushed open to both sides during the insertion of the terminal 2 into the slot 11, reducing the resistance when the terminal 2 is inserted.

[0033] like Figure 1 , Figure 4 As shown, in one embodiment of this utility model, the housing 1 is cylindrical, and a first opening 15 and a second opening 16 are respectively provided at both ends of the housing 1. The first opening 15 and the second opening 16 are arranged along the insertion direction of the terminal 2. Further, the opening directions of the first opening 15 and the second opening 16 are perpendicular to each other. In this embodiment, the first opening 15 is provided at one end of the housing 1, and its opening direction is parallel to the axial direction of the housing 1. The second opening 16 is provided on the other side of the housing 1, and its opening direction is perpendicular to the axial direction of the housing 1.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, in one embodiment of the present invention, the terminal 2 is provided with a plurality of plug-in pieces 22 to form a plug-in groove. The plug-in pieces 22 and the formed plug-in groove correspond to the second opening 16 for plugging into the plug of the high-voltage connector.

[0035] like Figures 3-5 As shown, in order to further improve the connection stability between terminal 2 and housing 1, a limiting ridge 17 is provided at one end of the slot 11 near the second opening 16, and terminal 2 is provided with a limiting groove 23 corresponding to the limiting ridge 17. When terminal 2 is inserted into place, the limiting ridge 17 is located in the limiting groove 23, limiting the shaking of terminal 2.

[0036] like Figures 1-3 As shown, in one embodiment of this utility model, the end of the terminal 2 near the first opening 15 is connected to the cable 3. Furthermore, an installation space 18 is provided between the cable 3 and the housing 1, the cross-section of which gradually increases in the direction from the second opening 16 to the first opening 15, facilitating the connection transition between the cable 3 and the terminal 2.

[0037] This utility model also provides a high-voltage connector, including the above-mentioned high-voltage connector terminal fixing structure.

[0038] This utility model provides a high-voltage connector terminal fixing structure and a high-voltage connector, which has the following advantages:

[0039] 1. The double-tongue structure ensures that the terminals are held more stably in the plug position;

[0040] 2. The recesses on both sides of the slot in the housing create a larger heat dissipation space, giving the terminals better heat dissipation.

[0041] 3. The ear plate on the hook makes it easier to remove the terminal;

[0042] 4. The terminals and housings are highly reusable, reducing the production and maintenance costs of the terminals.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
