Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted connection, in particular to a novel high-tolerance vehicle-mounted socket. Background Art

[0002] In electrical connections, especially in the field of new energy vehicles, vehicle-mounted sockets are widely used. Currently, vehicle-mounted sockets are symmetrical gap connections, and their defects are: after the plug end is inserted, there is an insertion position deviation or position tolerance, and it is difficult to ensure that the tolerance is met. When the unilateral extreme displacement continues and exceeds a certain size, the spring sheet on one side will be severely compressed, and the other side will not contact. Therefore, if the tolerance is not met, contact failure is likely to occur, and a good electrical connection cannot be achieved. Utility Model Content

[0007] The matching plug-in is inserted between the two rows of spring sheets in the center or offset on one side, and the cantilever contact body is elastically deformed and pressed to fit the two side surfaces of the matching plug-in.

[0012] In some embodiments, the upper end of the vertical sheet body of the elastic sheet is integrally connected to the lower part of the spring body, and the lower end is integrally connected to the upper surface of the shell wall of the seat body.

[0013] In some embodiments, the cantilever contacts of one row of spring sheets are located in the middle of the coordination gaps of another row of spring sheets.

[0014] Or the front end surface of the cantilever contact is at least flush with the front end surface of the coordination gap.

[0032] Figures 1 to 5 A new high-tolerance vehicle-mounted socket according to an embodiment of the utility model is schematically shown. As shown in the figure, the new high-tolerance vehicle-mounted socket comprises: a socket body 1, a spring sheet 2 and a lateral limit plate 3;

[0033] The seat body 1 is a shell body with upper and lower openings, and the seat body 1 can preferably be a rectangular shell body; two rows of spring plates 2 are connected to two opposite walls of the seat body 1, and two side limit plates 3 are symmetrically connected to the other two opposite walls;

[0034] Two rows of spring pieces 2 are arranged at equal intervals and are relatively cross-set, and coordination gaps 200 are formed between adjacent spring pieces 2 or between the end spring pieces 2 and the lateral limit plates 3. The cantilever contact 21 under the inner end of the spring piece 2 is located in the coordination gap 200. Preferably, one arc end of the arc-shaped spring body 20 of the spring piece 2 is integrally connected to the upper surface of the shell wall of the seat body 1 and the other arc end is integrally connected to the cantilever contact 21. The cantilever contact 21 can preferably be an outwardly curved arc sheet.

[0035] The matching plug-in unit 01 is inserted between the two rows of spring sheets 2 in a centered or unilateral manner, and the cantilever contact body 21 is elastically deformed and pressed tightly against the two side surfaces of the matching plug-in unit 01 .

[0036] like Figure 4As shown, the vehicle-mounted socket is in an ideal state, and the matching plug-in 01 is inserted in the center. At this time, the spring pieces 2 on both sides of the matching plug-in 01 are symmetrical, and expand and press tightly to fit the two sides of the matching plug-in 01 to achieve good contact;

[0037] like Figure 5 As shown, when the vehicle-mounted socket is in extreme unilateral displacement, the spring pieces 2 in the left row are in compression contact, and the spring pieces 1 in the right row are in tangential contact, and good contact is still achieved.

[0038] The beneficial effects of the new high-tolerance vehicle-mounted socket are as follows: first, the two rows of spring pieces 2 are cross-arranged, and the cantilever contact body 21 is located in the matching gap 200. By inserting the matching plug-in 01 in the center or offset, the two rows of spring pieces 2 can be displaced as required, and the spacing between the two spring pieces can be adjusted flexibly. The tolerance can meet the matching contact under any displacement, so it has a large tolerance and can still meet the effective contact under the extreme displacement state, and can achieve good electrical connection; second, the structure can be used in a variety of scenarios, especially scenarios that require effective contact under conditions with large tolerances, such as automated installation of matching ends, with large displacement tolerance, and this structure has a large tolerance, which just meets the requirements; third, the structure is simple, easy to form and produce, and has good cost; fourth, the spring pieces 2 of this structure have good elasticity, and at the same time, the setting of the cantilever contact body 21 and the matching gap 200 can achieve effective compression on both sides without left and right deviation.

The beneficial effects are: the structure is simple, convenient for processing and molding, and low cost.

[0041] Preferably, a rounded corner is provided at the connection between the cantilever contact body 21 and the spring body 20. The beneficial effect is that the structure can effectively improve the strength of the connection.

The beneficial effect is that the structure is simple, convenient for processing and molding, and low in cost.

[0043] Furthermore, the intervals between the two rows of spring sheets 2 are the same, and the cantilever contacts 21 of one row of spring sheets 2 are located in the middle of the coordination gaps 200 of the other row of spring sheets 2, that is, the center line of the spring sheet 2 is the same as the symmetry line of the two spring sheets 2 in the other row.

[0044] Or the front end surface of the cantilever contact 21 is at least flush with the front end surface of the coordination gap 200.

[0045] Furthermore, the upper ends of the two lateral limiting plates 3 are also formed with outward turning guides 31. The beneficial effect is that the outward turning guides 31 have a good limiting effect.

[0046] Furthermore, a group of opposite wall lower surfaces of the seat body 1 are symmetrically connected to a plurality of pins 4, and the lower ends of the pins 4 are fixed on the PCB board 02; preferably, the lower ends of the pins 4 are provided with elastic ends 41 bent outward, and the elastic ends 41 are pre-installed and connected to the fixing holes 021 on the PCB board 02 by expansion and interference, and then the two are welded into one. Its beneficial effect is that the structure can achieve accurate fixed connection.

[0047] Furthermore, a plurality of positioning blocks 5 are symmetrically arranged on the lower surface of another set of opposite walls of the seat body 1, and the positioning blocks 5 are fitted with the upper surface or positioning groove of the PCB board 02. The beneficial effect is that the positioning blocks 5 can improve the positioning accuracy.

[0048] Preferably, the seat body 1 is a flat sheet material with features punched out, which is then relatively bent to form an integral body, and the joint of the seat body 1 is provided with matching recesses and protrusions.

[0049] Furthermore, the base body 1 and the associated PCB board 02 are installed in the housing. The beneficial effect is that the housing can effectively protect the product.
