Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage protection equipment, in particular to an insulation protection component of a conductive plug-in. Background Art

[0002] The battery system includes a battery box, a battery cell and a conductive plug-in. The battery cell is arranged in the battery box, the conductive plug-in is installed on the side wall of the battery box, and one end of the conductive plug-in is connected to the battery cell, and the other end of the conductive plug-in passes through the side wall of the battery box and extends outside the battery box. The conductive plug-in includes a positive electrode plug-in protruding from the inside of the battery box and a negative electrode plug-in spaced from the positive electrode plug-in. The positive electrode plug-in is electrically connected to the positive electrode of the battery cell, and the negative electrode plug-in is electrically connected to the negative electrode of the battery cell.

[0003] Generally, for battery systems with voltages higher than 50V, there are certain requirements for the electrical clearance and creepage clearance between the two poles. However, for highly integrated and standardized electrical conductive plug-ins, the spacing between the positive plug-in and the negative plug-in is small. After the positive plug-in is connected to the positive pole of the battery cell and the negative plug-in is connected to the negative pole of the battery cell, the electrical clearance and creepage clearance between the two poles are too small to meet the requirements. Therefore, protective measures are required for the electrical plug-ins.

[0004] The protective measures for the conductive plug-in in the related art are usually to manually use a soft silicone sleeve to wrap the connection part between the positive electrode of the battery cell and the positive electrode plug-in and the connection part between the negative electrode of the battery cell and the negative electrode plug-in after connecting the positive electrode plug-in to the positive electrode of the battery cell and the negative electrode plug-in. However, this protective measure has the following shortcomings:

[0005] 1. The soft silicone cover has poor wrapping and is not tightly wrapped, so it is easy to fall off when impacted;

[0006] 2. When wrapping the soft silicone sleeve, the space between the positive and negative plug-ins is limited, which is not conducive to operation;

[0007] 3. If your fingers touch the positive and negative electrodes at the same time while wrapping the soft silicone cover, it will cause a short circuit in the battery system, posing a safety hazard. Utility Model Content

[0039] In order to make the technical problems solved by the utility model, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the utility model will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0042] like Figures 1 to 8 As shown, the utility model provides an insulating protection component of a conductive plug (hereinafter referred to as insulating protection component 100). The insulating protection component 100 and the conductive plug 300 are generally used in high-voltage equipment, such as a battery device. The specific structure of the insulating protection component 100 is described in detail below by taking the application of the insulating protection component 100 and the conductive plug 300 in a battery device as an example.

[0043] The battery device includes a battery box 200, a battery cell, a conductive plug-in 300 and an insulating protective component. The battery cell is arranged inside the battery box 200. The side wall of the battery box 200 is provided with a plug hole, which runs through the inside and outside of the battery box 200. The conductive plug-in 300 is inserted into the plug hole, and the insulating protective component is arranged inside the battery box 200. The conductive plug-in 300 is installed on the battery box 200 (i.e., a carrier). In this embodiment, the battery box 200 is a battery box (i.e., a carrier). The conductive plug-in 300 includes a positive plug-in 400 and a negative plug-in 500 spaced apart along a first direction (the first direction is the X direction shown in the figure). The positive plug-in 400 is connected to the positive conductive member 600 of the battery cell, and the negative plug-in 500 is connected to the negative conductive member 700 of the battery cell. The insulating protection assembly 100 includes an insulating support 1 and an insulating partition 2. The insulating support 1 is arranged on the battery box 200 (i.e., the carrier) and is located on one side of the conductive plug-in 300 along the second direction (the second direction is the Y direction shown in the figure). The second direction is arranged at an angle with the first direction. Along the second direction, the insulating support 1 has a first side surface 15 close to the conductive plug-in 300. The first side surface 15 is provided with an insulating partition 2, and the insulating partition 2 is inserted between the negative plug-in 500 and the positive plug-in 400 to separate the negative plug-in 500 from the positive plug-in 400. In this embodiment, the first direction is arranged perpendicular to the second direction. When the battery device is in use, the second direction can be a vertical direction parallel to the gravity direction, and at this time, the insulating support 1 can be arranged above the positive plug-in 400 and the negative plug-in 500. The insulating support 1 and the insulating partition 2 are both plastic parts. Of course, in other examples, the insulating support 1 and the insulating partition 2 can also be wood or insulating silica gel, etc., and the materials of the insulating support 1 and the insulating partition 2 are not specifically limited here.

[0044] An insulating partition 2 is provided between the positive electrode plug-in 400 and the negative electrode plug-in 500. The positive electrode plug-in 400 and the negative electrode plug-in 500 are separated by the insulating partition 2, so that the two poles form an effective barrier insulation, thereby effectively increasing the electrical gap and creepage distance between the two poles, reducing the possibility of short circuit between the two poles, and improving safety.

[0045] Reference Figure 7 and Figure 8 Before the insulating protection component 100 is used to protect the conductive plug-in 300 (i.e., when no insulating partition 2 is provided between the positive plug-in 400 and the negative plug-in 500), the electrical gap between the two poles is L1, and the creepage distance between the two poles is H1; when the insulating protection component 100 is used to protect the conductive plug-in 300 (i.e., when an insulating partition 2 is provided between the positive plug-in 400 and the negative plug-in 500), the electrical gap between the two poles is L2=a1+a2+a3, and the creepage distance between the two poles is H2=b1+b2+b3+b4+b5. It can be seen that this insulating protection component 100 can effectively increase the electrical gap and creepage distance between the two poles.

[0046] In actual implementation, in order to facilitate the insertion of the conductive plug 300 into the socket, the cross-sectional dimension of the socket is usually set to be larger than the cross-sectional dimension of the conductive plug 300. Based on this, the battery box 200 (i.e., the carrier) is provided with a socket for the conductive plug 300 to be inserted, and the socket runs through two opposite sides of the battery box (i.e., the carrier). Along the second direction, the insulating bracket 1 has a second side 16 away from the conductive plug 300. The insulating protection component 100 also includes a shielding plate 4, which is protruding from the second side 16, i.e., a side of the insulating bracket 1 away from the positive plug 400 or the negative plug 500. The shielding plate 4 is used to block the gap between the conductive plug 300 and the hole wall of the socket. Through the shielding of the shielding plate 4, water vapor, dust, etc. can be blocked from entering the battery box 200, so that the battery device meets the IPXXB protection (i.e., contact protection) requirements.

[0047] In this example, the shielding plate 4 is a plastic part. Preferably, the shielding plate 4 and the insulating bracket 1 are integrally formed.

[0048] Reference Figure 1 and Figure 5 The second side surface 16 is also provided with a first reinforcing rib 11 protruding therefrom. Figure 6 The first side surface 15 is protrudingly provided with a second reinforcing rib 12 , and the overall structural strength of the insulating bracket 1 can be enhanced by the reinforcing rib.

[0049] In another example, the first reinforcing rib 11 may be protrudingly provided only on the second side surface 16 , or the second reinforcing rib 12 may be protrudingly provided only on the first side surface 15 .

[0050] Preferably, the first reinforcing rib 11 includes a first reinforcing portion 111, two second reinforcing portions 112 and a plurality of third reinforcing portions 113, the baffle plate 4 and the first reinforcing portion 111 are arranged on the second side surface 16 and are respectively close to the two sides of the insulating bracket 1 along the third direction (the third direction is the Z direction shown in the figure), the two sides of the baffle plate 4 along the first direction are respectively connected to the first reinforcing portion 111 through a second reinforcing portion 112, all the third reinforcing portions 113 are arranged between the two second reinforcing portions 112, and the length of the third reinforcing portion 113 extends along the third direction, and the two ends of the third reinforcing portion 113 along the third direction are respectively connected to the first reinforcing portion 111 and the baffle plate 4, wherein the first direction, the second direction and the third direction are arranged at angles to each other. In this embodiment, the first direction, the second direction and the third direction are arranged perpendicular to each other. It can be understood that the two ends of the baffle plate 4 along the first direction are respectively connected to the two ends of the first reinforcement part 111 through a second reinforcement part 112, and the second reinforcement part 112 extends along the outer edge of the second side surface 16. Through the setting of the second reinforcement part 112, the structural strength of the baffle plate along the first direction can be strengthened. Through the combined action of multiple third reinforcement parts 113 on the baffle plate 4, the connection strength between the baffle plate 4 and the insulating bracket 1 is effectively improved.

[0051] When the first side surface 15 has the second reinforcing rib 12 , the insulating partition 2 is connected to the second reinforcing rib 12 . This design can utilize the second reinforcing rib 12 to strengthen the connection structure between the insulating partition 2 and the insulating bracket 1 .

[0052] Preferably, at least one of the two sides of the insulating partition 2 along the first direction is provided with a reinforcing rib group, and each reinforcing rib group includes at least two second reinforcing ribs 12 arranged at intervals along the third direction, the length of the second reinforcing ribs 12 extends along the first direction, and at least two adjacent second reinforcing ribs 12 in each group of second reinforcing ribs 12 are connected to each other, further strengthening the connection strength and connection stability between the insulating partition 12 and the insulating bracket 1. In this embodiment, the insulating partition 2 is provided with a reinforcing rib group on both sides along the first direction, and each group is respectively provided with three second reinforcing ribs 12 arranged at intervals along the third direction, and the three second reinforcing ribs 12 are connected to each other in pairs, and the structure is connected stably.

[0053] In one embodiment, referring to Figures 1 to 6The insulating protection assembly also includes a support member 3, one end of which is connected to the insulating bracket 1, and the other end of the support member 3 is arranged on the bearing member, and the support member 3 is arranged to facilitate the connection of the insulating bracket 1. Preferably, the insulating protection assembly also includes a connector and a fastener 6, one end of the support member 3 is detachably connected to the insulating bracket 1 through the connector, and the other end of the support member 3 is detachably arranged on the bearing member through the fastener 6, and the insulating bracket 1 is provided with a first connecting hole, and the first connecting hole passes through both sides of the insulating bracket 1 along the second direction, and one end of the support member 3 is provided with a second connecting hole, and the first connecting hole and the second connecting hole are both provided for the connector to pass through. The insulating bracket 1 is detachably connected to the support member 3 through the connector, which facilitates the assembly of the insulating protection assembly 100. In this example, the connecting member is a connecting bolt 5, which includes a connecting nut 52 and a connecting screw 51 threadedly connected to the connecting nut 52. The connecting nut 52 is fixed on the support member 3, and the axis line of the connecting nut 52 coincides with the axis line of the second connecting hole. The connecting screw 51 passes through the first connecting hole and the second connecting hole and is tightened in the connecting nut 52, thereby realizing a detachable connection between the support member 3 and the insulating bracket 1.

[0054] The support member 3 mainly plays the role of supporting the insulation protection component 100 as a whole. One end of the support member 3 is connected to the insulation bracket 1, and the other end of the support member 3 is fastened to the supporting member through the fastener 6. With this design, the insulation protection component 100 will not be restricted by the space between the positive plug-in 400 and the negative plug-in 500 when being installed, which is convenient for installation. It can also make the insulation bracket 1 firmly locked on the battery box 200 to prevent the insulation partition 2 from falling off from between the positive plug-in 400 and the negative plug-in 500, thereby improving the reliability of the insulation protection component 100. In addition, during use, the insulation bracket 1 is not easy to move relative to the positive plug-in 400 or the negative plug-in 500, thereby avoiding the insulation bracket 1 from colliding with the positive and negative plug-ins to generate noise.

[0055] Specifically, the support member 3 includes a first support plate 31 and a second support plate 32 connected to the first support plate 31 at an angle, the second connection hole is provided on the first support plate 31, the first support plate 31 is connected to the insulating bracket 1, and the second support plate 32 is connected to the battery box (i.e., the carrier) through a fastener 6. In this example, the fastener 6 is a fastening screw.

[0056] In this example, the first support plate 31 is perpendicular to the second support plate 32, so that the support member is in an L-shaped structure. In other examples, the angle between the first support plate 31 and the second support plate 32 can be flexibly adjusted as needed.

[0057] Preferably, at least two support members 3 are provided, and all the support members 3 are arranged on the insulating bracket 1 at intervals along the first direction. The insulating bracket 1 is supported by two support members 3, so that the insulating protection assembly 100 is effectively connected to the battery box (i.e., the carrier), thereby reducing the possibility of the insulating protection assembly 100 falling off the battery box 200.

[0058] In this example, three support members 3 are provided, two support members 3 are provided at opposite ends of the length direction of the insulating support 1 (the length direction of the insulating support 1 is the first direction), and the remaining one is provided in the middle of the insulating support member 3. The battery box 200 includes a first box side wall 201 and a second box side wall 202 connected to the first box side wall 201 at an angle, the support member 3 at one end of the length direction of the insulating space and the support member 3 in the middle are fastened to the first box side wall 201, and the support member 3 at one end of the length direction of the insulating space is fastened to the second box side wall 202, so that the insulating protection assembly 100 can be fixed by two different box side walls of the battery box 200.

[0059] When a reinforcing beam is provided on the inner wall of the battery box 200 , the support member 3 may be connected to the reinforcing beam via the fastener 6 .

[0060] As a preferred embodiment, at least two insulating separators 2 are provided, and all insulating separators 2 are spaced apart along the length direction of the insulating support 1. By providing at least two insulating separators 2, at least two conductive plug-ins 300 can share one insulating protection assembly 100. In this embodiment, each conductive plug-in 300 includes a negative electrode plug-in 500 and a positive electrode plug-in 400, and the negative electrode plug-in 500 corresponds to the negative electrode conductive member 700 one by one, and the positive electrode plug-in 400 corresponds to the positive electrode conductive member 600 one by one.

[0061] In this example, the battery device includes two conductive plug-ins 300, and two sockets are provided on the same side wall of the battery box 200, and a conductive plug-in 300 is inserted into each socket. Two insulating partitions 2 are provided, and the insulating partitions 2 correspond to the conductive plug-ins 300 one by one, that is, an insulating partition 2 is provided between the negative electrode plug-in 500 and the positive electrode plug-in 400 in each conductive plug-in 300. By sharing an insulating protection component 100 with the two conductive plug-ins 300, the internal structure of the battery box 200 is made more compact, which is particularly suitable for two adjacent conductive plug-ins 300.

[0062] Optionally, the positive electrode plug-in 400 is fixed to the positive electrode conductive member 600 of the battery cell through a first fixing member, one end of the first fixing member protrudes toward the insulating bracket 1 to form a first protrusion, and the first side surface 15 is provided with a plurality of first grooves 13, and the first protrusion is inserted into the first groove 13. Specifically, the first fixing member is a first fixing bolt 800, and the first fixing bolt 800 includes a first fixing nut 802 and a first fixing screw 801 threadedly connected to the first fixing nut 802. The end of the positive electrode conductive member 600 away from the battery cell is the positive electrode connecting portion 602, and the positive electrode connecting portion 602 is a bare metal conductor. The portion of the positive electrode conductive member 600 between the positive electrode connecting portion 602 and the battery cell is wrapped with a first insulating layer 601. The positive electrode plug-in 400 is provided with a first fixing hole, and the first fixing nut 802 is fixed to the lower side of the positive electrode plug-in 400, and the axis of the first fixing nut 802 is aligned with the center of the first fixing hole. The center lines coincide, and the positive electrode connection part 602 is provided with a second fixing hole. After the positive electrode connection part 602 is overlapped on the upper side of the positive electrode plug-in 400, the lower end of the first fixing screw 801 is passed through the second fixing hole and the first fixing hole and then tightened in the first fixing nut 802. The nut of the first fixing screw 801 protrudes from the top of the positive electrode connection part 602 (that is, protrudes toward the insulating bracket 1) to form a first protrusion. During the assembly of the insulating protection bracket and the battery box 200, the first protrusion can be inserted into the first groove 13 to preliminarily position the protective insulating bracket 1 and the battery box 200, which is beneficial to improve the installation speed of the insulating protection component 100.

[0063] In order to ensure the structural strength of the support member 3, the support member 3 is made of steel or aluminum alloy.

[0064] Optionally, the negative electrode plug-in 500 is fixed to the negative electrode conductive member 700 of the battery cell through a second fixing member, one end of the second fixing member protrudes toward the insulating bracket 1 to form a second protrusion, the first side surface 15 is provided with a second groove 14, and the second protrusion is inserted into the second groove 14. Specifically, the second fixing member is a second fixing bolt 900, and the second fixing bolt 900 includes a second fixing nut 902 and a second fixing screw 901 threadedly connected to the second fixing nut 902. The end of the negative electrode conductive member 700 away from the battery cell is the negative electrode connection part, and the negative electrode connection part is a bare metal conductor. The part of the negative electrode conductive member 700 located between the negative electrode connection part and the battery cell is wrapped with a second insulating layer. The negative electrode plug-in 500 is provided with a third fixing hole, and the second fixing nut 902 is fixed to the lower side of the negative electrode plug-in 500, and the axis of the second fixing nut 902 is aligned with the center of the third fixing hole. The lines overlap, and the negative electrode connecting part is provided with a fourth fixing hole. After the negative electrode connecting part is overlapped on the upper side of the negative electrode plug-in 500, the lower end of the second fixing screw 901 is passed through the fourth fixing hole and the third fixing hole and then tightened in the second fixing nut 902. The nut of the second fixing screw 901 protrudes from the top of the negative electrode connecting part (that is, protrudes toward the insulating bracket 1) to form a second convex portion.
