Description

[0002] With the rapid development of new energy industry, the working voltage of vehicle electrical system is continuously improved, prompting the use amount and thickness of the conducting busbar such as copper bar or aluminum bar for connection to increase significantly. In order to ensure the electrical performance of the product and take into account the safety of the vehicle, the plastic coated conducting busbar becomes the mainstream scheme in the industry, but in the injection molding process, although the conducting busbar has certain rigidity, it is easy to bend and deform under the high pressure impact of molten plastic, resulting in the reduction of the distance between adjacent conducting busbars, causing insufficient electrical clearance or local filling defects, which poses a safety hazard of insulation failure leading to short circuit.
[0003] The traditional solution generally uses mold positioning pins or positioning blocks to mechanically position the conducting busbar, but such rigid positioning structure is easy to cause uneven thickness of the coating layer, resulting in incomplete plastic coverage in the local area of the conducting busbar and forming exposed parts. To make up for this defect, manual dispensing is still needed to fill the exposed area to ensure the insulation performance, but the dispensing process is limited by the curing time of the glue (usually 0.5-1 hour), which seriously restricts the production rhythm efficiency, and there is a risk of adhesive detachment due to insufficient adhesive adhesion, which further affects the long-term reliability of the product.

The cooperation of multiple side plates can make the conducting busbar maintain a stable posture under high pressure flow impact, without the need for additional openings, which can eliminate the risk of exposure caused by process holes and eliminate the restriction of subsequent dispensing process on production rhythm.

[0037] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the first aspect of the embodiment of the utility model provides a limiting clamp 20 for a conductive busbar, for the convenience of explanation, hereinafter, the limiting clamp 20 is abbreviated as a simple term; the limiting clamp 20 comprises a first side plate 100, a second side plate 200 and a third side plate 300, one side of the first side plate 100 is used for abutting to an injection mold (not shown in the figure), the other side of the first side plate 100 is used for abutting to one side of the conductive busbar 10.
[0038] The second side plate 200 is arranged opposite to the first side plate 100, one side of the second side plate 200 away from the first side plate 100 is used for abutting to the injection mold, the other side of the second side plate 200 is used for abutting to the other side of the conductive busbar 10; the third side plate 300 is arranged on the same side of the first side plate 100 and the second side plate 200 and is connected with the first side plate 100 and the second side plate 200 respectively, one side of the third side plate 300 towards the first side plate 100 is used for abutting to the conductive busbar 10, the other side of the third side plate 300 is used for abutting to the injection mold.
[0039] In use, first, the limiting clamp 20 is pressed into the conductive busbar 10 from one side of the conductive busbar 10, so that the two form a temporary whole, then the injection mold is sleeved on the outside of the limiting clamp 20 and the conductive busbar 10, and finally injection molding and waiting for cooling demolding can be carried out; the limiting clamp 20 after manufacturing will form a whole with the conductive busbar 10 and the injection material wrapped on the outside, and then the next process of the product is carried out, for example, the whole is used as part of the filter or high-voltage connector for assembly, specifically, adaptive design can be made according to actual needs.
[0040] Referring to Figure 1 , Figure 2 and Figure 3 It can be understood that, in the limiting clamp 20 provided by the embodiment of the utility model, the limiting clamp 20 is combined by the first side plate 100, the second side plate 200 and the third side plate 300, which can form multidirectional abutment constraints between the conductive busbar 10 and the mold during injection molding: the first side plate 100 and the second side plate 200 abut the two sides of the conductive busbar 10 respectively, and contact the mold cavity through the outside thereof, thereby inhibiting the lateral displacement of the conductive busbar 10; the third side plate 300 limits the longitudinal displacement of the conductive busbar 10. The cooperation of the multiple side plates can make the conductive busbar 10 maintain a stable posture under the impact of high-pressure flow, thereby avoiding the problem of reduced spacing or insufficient filling between adjacent conductive busbars 10 due to displacement.
[0041] Compared with the traditional mold positioning needle or positioning block which needs to open a process hole on the conductive busbar 10, causing the defect of incomplete local coating, the embodiment of the utility model forms a temporary whole by preassembling the limiting clamp 20 and the conductive busbar 10 and then directly injection molding, without the need for additional hole opening, which not only eliminates the risk of exposure caused by the process hole, but also saves the restriction of subsequent dispensing process on the production rhythm. At the same time, the integrated packaging of the limiting clamp 20 and the injection material also avoids the hidden danger of the adhesive layer falling off in the traditional dispensing process, and the standardized design of the limiting clamp 20 can simplify the mold adaptation complexity, which can effectively improve the production efficiency and product consistency.
[0042] Continuing to refer to Figure 1 and Figure 2 In the optional embodiment of the utility model, the limiting clamp 20 further comprises at least one creepage resistance separating component 600, which is arranged between the first side plate 100 and the second side plate 200 and connected with the third side plate 300; in the case that the conductive busbar 10 is provided with two or more than two, the creepage resistance separating component 600 is used to increase the creepage distance between the conductive busbar 10 and the adjacent conductive busbar 10.
[0043] Specifically, the conductive busbar 10 can be provided with one, two, three or more, that is, the utility model embodiment is aimed at the situation that two and more conductive busbars 10 are arranged side by side, in this case, the adjacent two conductive busbars 10 need to be provided with the creepage resistance separation component 600, and the specific number of the creepage resistance separation component 600 needs to be designed according to the actual design number of the conductive copper bar, for example, when the conductive busbar 10 is two, the creepage resistance separation component 600 needs to be provided with one, when the conductive busbar 10 is three, the creepage resistance separation component 600 needs to be provided with two, from another angle, the limiting clamp 20 provided by the utility model embodiment has different models, for example, the limiting clamp 20 including a single creepage resistance separation component 600, the limiting clamp 20 including two creepage resistance separation components 600 and the like, in use, the limiting clamp 20 of a suitable model can be selected according to the structure of the actual conductive busbar 10.
[0044] It can be understood that the creepage resistance separation component 600 added in the utility model embodiment extends from the gap between the conductive busbars 10 to both sides when the plurality of conductive busbars 10 are arranged side by side, can force the current to bypass along the surface of the insulating material of the creepage resistance separation component 600, thereby prolonging the effective creep path between the conductive busbars 10 and reducing the risk of breakdown caused by insufficient electrical gap.
[0045] Continuing to refer to Figure 1 and Figure 2 In the optional embodiment of the utility model, the creepage resistance separation component 600 includes at least one blocking piece 610, the blocking piece 610 is arranged between the first side plate 100 and the second side plate 200 and is connected with the third side plate 300, in the case that the creepage resistance separation component 600 includes a plurality of blocking pieces 610, the plurality of blocking pieces 610 are arranged at intervals along the length direction of the third side plate 300, Figure 1 As shown in the figure, the creepage resistance separation component 600 includes two blocking pieces 610.
[0046] It can be understood that in the utility model embodiment, the creepage resistance separation component 600 is arranged at intervals by a plurality of blocking pieces 610 between the first side plate 100 and the second side plate 200, and is distributed along the length direction of the third side plate 300, which can form a multi-point physical separation of the conductive busbar 10, and can break the limitation of the distance between the conductive busbar 10 and the adjacent conductive busbar 10 on the creepage distance.
[0047] Specifically, each barrier 610 independently acts in the extension direction of the conductive busbar 10, and can force the current to bypass the barrier 610 to form a stepped path along the surface of the insulating material, thereby further extending the effective creepage path between adjacent conductive busbars 10, and reducing the risk of breakdown caused by local electric field concentration. When a plurality of barriers 610 are used, the interval distribution can cover a larger area of the conductive busbar 10 to strengthen the overall insulation barrier effect, and can also avoid the problem of material redundancy or injection filling difficulty caused by continuous barriers.
[0048] In an optional embodiment of the utility model, the surface of the barrier 610 is provided with a groove, and in other optional embodiments of the utility model, the surface of the barrier 610 can also be provided with a protrusion, or the groove and the protrusion are provided together. It can be understood that the groove or the protrusion provided on the surface of the barrier 610 can change the geometric shape of the surface of the barrier 610, and force the current to bypass along the inner wall of the groove or the outer edge of the protrusion, thereby further extending the effective creepage path between the conductive busbars 10.
[0049] In addition, when the groove and the protrusion are combined, the staggered distribution of the undulating structure can form a multiple circuitous creepage path, effectively increasing the current bypass distance on the surface of the insulating medium in a limited space, thereby strengthening the anti-tracking ability of the local area.
[0050] Continuing to refer to Figure 1 In an optional embodiment of the utility model, the side surface of the third side plate 300 is provided with a creepage barrier 310, the position of the creepage barrier 310 corresponds to the position of the creepage barrier 600 one by one, and the creepage barrier 310 is used to increase the creepage distance between the conductive busbar 10 and the adjacent conductive busbar 10. In other words, the creepage barrier 310 is arranged between any two adjacent conductive busbars 10. Specifically, the creepage barrier 310 can include at least one of a groove and a protrusion.
[0051] It can be understood that in this way, when the creepage barrier 310 adopts a groove or a protrusion structure, the surface undulation can force the current to bypass along the inner wall of the groove or the outer edge of the protrusions, thereby extending the creepage path length between the conductive busbars 10. If the groove and the protrusion are combined, the staggered distribution of the geometric features can further increase the circuitous degree of the surface of the insulating medium, effectively increasing the current bypass distance in a limited space to suppress local electric field concentration.
[0052] Continuing to refer to Figure 1 and Figure 2 In an optional embodiment of the utility model, at least one of the side of the first side plate 100 away from the second side plate 200, the side of the second side plate 200 away from the first side plate 100, and the side of the third side plate 300 away from the first side plate 100 is provided with a protrusion 400, and the protrusion 400 is used to abut to an injection mold. Figure 1The first side plate 100, the second side plate 200 and the third side plate 300 are all provided with the protruding part 400. It should be noted that the position of the protruding part 400 needs to be adaptively designed according to the distribution of the limiting clamps 20, for example, the protruding part 400 is arranged at the center of the first side plate 100, so that the unbalanced stress can be avoided.
[0053] It can be understood that, in the embodiment of the utility model, the protruding part 400 arranged outside the side plate forms multi-point positioning support through abutting with the mold cavity, so that the clamp can still maintain a stable posture when being impacted by the flow during the injection molding process, and the deflection or displacement caused by uneven local stress can be avoided; at the same time, the area (thinning area) outside the protruding part 400 can form a space difference with the surface of the protruding part 400, so that sufficient gap can exist between the first side plate 100, the second side plate 200 and the third side plate 300 and the injection mold, so that a suitable flow channel can be provided for the molten plastic during the injection molding process, the flowability of the molten plastic in the area is enhanced, and then it can be ensured that the injection material can fully fill the gap between the clamp and the mold during the plastic wrapping, and problems such as insufficient filling, air gap remaining or plastic wrapping sectional gap caused by sudden change of wall thickness can be avoided.
[0054] Secondly, the cooperative design of the protruding part 400 and the thinning area can not only constrain the displacement of the conductive busbar 10 through the rigid contact of the protruding part 400, but also realize dense coverage of the plastic wrapping layer by using the material flowability of the thinning area, so that the positioning accuracy of the conductive busbar 10 and the insulation integrity of the plastic wrapping layer can be simultaneously improved without additional process adjustment, the mold adaptation complexity is simplified, and then the consistency of the appearance and performance of the conductive busbar 10 after plastic wrapping and molding is ensured.
[0055] Continuously referring to Figure 1 and Figure 2 In the optional embodiment of the utility model, the side of the first side plate 100 facing the second side plate 200 is provided with a clamping part 500, and in the another optional embodiment of the utility model, the side of the second side plate 200 facing the first side plate 100 can also be provided with the clamping part 500, and the specific shape of the clamping part 500 can be protrusion or groove, and the corresponding recess or protrusion is arranged on the conductive busbar 10.
[0056] When the limiting clamp 20 is pressed into the conductive busbar 10, the clamping part 500 on the first side plate 100 or the clamping part 500 on the second side plate 200 can be clamped with the corresponding clamping structure on the conductive busbar 10, and then the interlocking limiting of the two is realized.
[0057] It can be understood that the clamping part 500 provided in the embodiment of the utility model can be interlocked with the corresponding structure on the conductive busbar 10 through the protrusion or the groove, and mechanical engagement is formed when the limiting clamp 20 is pressed into the conductive busbar 10, so that the two can still be relatively fixed when they withstand the material flow impact in the injection molding process, avoiding the clamp slipping or falling off due to external force.
[0058] Referring to Figure 3 and Figure 4 , the second aspect of the embodiment of the utility model provides a conductive busbar structure, which comprises a conductive busbar 10 and the limiting clamp 20 described in any of the preceding embodiments, and the limiting clamp 20 is arranged on the conductive busbar 10 and is used for limiting the position of the conductive busbar 10. It can be understood that the conductive busbar structure provided in the embodiment of the utility model also has the technical effects of the limiting clamp 20 in any of the preceding embodiments because it comprises the limiting clamp 20 in any of the preceding embodiments. Specifically, reference can be made to the foregoing description, which will not be repeated here.
[0059] Continuing to refer to Figure 3 , the limiting clamps 20 are arranged on both sides of the conductive busbar 10 in pairs in the optional embodiment of the utility model. Specifically, they can be arranged symmetrically along the same line, as shown in Figure 3 ; in some optional examples, they can also be arranged staggeredly, for example, the limiting clamps 20 can be arranged according to the distribution of the peaks and valleys of a sine curve, and can be adaptively arranged according to the actual situation. It should be noted that when arranged staggeredly, there can be one limiting clamp 20 left, in which case, another limiting clamp 20 is added to form a "pin" shape assembly. From another point of view, staggered arrangement can also be understood as "pin" distribution, that is, every three limiting clamps 20 form a group, and specifically, they can be adaptively arranged according to the actual situation.
[0060] It can be understood that the pair arrangement of the limiting clamps 20 in the embodiment of the utility model forms multidirectional constraint through symmetric or staggered arrangement. When symmetrically distributed along the same line, the abutting forces of the clamps on both sides are balanced, so that the conductive busbar 10 can withstand uniform transverse constraint force in the injection molding process, thereby avoiding deflection or torsion caused by unilateral force; and the staggered arrangement (such as the distribution of the peaks and valleys of a sine curve) disperses the flow impact energy through the asymmetric distribution of contact points, so that progressive buffering is formed under dynamic injection pressure, and local deformation or vibration of the conductive busbar 10 is inhibited.
[0061] Whether symmetrically or staggeredly arranged, the multidirectional action of the clamps can cover a larger area of the conductive busbar 10, so that the positioning stability can be ensured, and the layout mode can be flexibly adapted (such as adjusting the clamp spacing according to the bending degree of the conductive busbar 10 or the characteristics of the mold cavity) to meet the plastic packaging requirements under different working conditions.
[0062] It should be noted that in some optional embodiments, the limiting clamp 20 can also be arranged on one side of the conductive busbar 10, and when arranged in this way, the first side plate 100 and the second side plate 200 of the conductive busbar 10 need to be lengthened, and the abutting center of the injection mold is located at the center of the conductive busbar 10, so as to avoid force imbalance, and specifically, the actual situation can be adapted.
[0063] It should be noted that the technical solutions in each embodiment of the utility model can be combined with each other, but the basis for mutual combination is that it can be realized by ordinary skilled personnel in the art; when the combination of technical solutions is contradictory or cannot be realized, it should be considered that the combination of technical solutions does not exist, that is, it does not belong to the protection scope of the utility model.
[0064] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of each embodiment of the utility model.
