Detailed Embodiments

[0031] Embodiments of the present utility model will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present utility model will be described in detail below.

[0032] Next, refer to Figures 1-4 to describe the port assembly 1 of a battery according to an embodiment of the present utility model. The port assembly 1 of the battery can be used for the connection and assembly of a blade battery cover assembly.

[0033] As Figure 1 and Figure 2 shown, for the port assembly 1 of a battery according to an embodiment of the present utility model, the port assembly 1 is disposed inside the battery. The battery includes a pole core, and the port assembly 1 is located at the end of the pole core and includes: a top spacer 10 and an inner spacer 20. The port assembly 1 is disposed inside the battery, a pole core is disposed inside the battery, and the port assembly 1 is disposed at the end of the pole core. In this way, the functions that the port assembly 1 can play are: on the one hand, the edge mounts the cover assembly 1 and is insulated from the cover, and on the other hand, it is used to fix the pole core and the pole ear, making the battery structure more stable. The top spacer 10 and the inner spacer 20 are components of the port assembly 1. The top spacer 10 and the inner spacer 20 are snap-connected to form the port assembly 1.

[0034] As Figure 3 and Figure 4 shown, the top spacer 10 includes: a first main body portion 100 and a first snap-connection portion 101. The first snap-connection portion 101 is disposed on the side surface of the first main body portion 100. The first main body portion 100 is the main part of the top spacer 10 and can be used to connect and set other components. The first snap-connection portion 101 is a component of the top spacer 10. The first snap-connection portion 101 mainly plays the role of snap-connection and fixation. The first snap-connection portion 101 is disposed on the side surface of the first main body portion 100. In this way, the first snap-connection portion 101 and the first main body portion 100 form an integral body, facilitating the installation and setting of the top spacer 10.

[0035] As Figure 3 and Figure 4As shown in the figure, the internal spacer ring 20 includes: a second main body portion 200 and a second clamping portion 201. The second clamping portion 201 is provided on the side surface of the second main body portion 200, and the first clamping portion 101 is in clamping cooperation with the second clamping portion 201. The second main body portion 200 is the main part of the internal spacer ring 20 and can be used to connect and arrange other components. The second clamping portion 201 is a component of the internal spacer ring 20, and the second clamping portion 201 mainly plays a role in clamping and fixing connections. The second clamping portion 201 is provided on the side surface of the second main body portion 200, so that the second clamping portion 201 and the second main body portion 200 form a whole, which is convenient for the installation and setting of the internal spacer ring 20. The first clamping portion 101 is in clamping cooperation with the second clamping portion 201. The clamping connection method is simple and convenient, and can make the connection between the top spacer ring 10 and the internal spacer ring 20 firm and reliable.

[0036] Therefore, the first clamping portion 101 is arranged on the side surface of the first main body portion 100, and the second clamping portion 201 is arranged on the side surface of the second main body portion 200. In this way, the first clamping portion 101 can be adjusted within the maximum outer shape of the port assembly 1, which can prevent the first clamping portion 101 from protruding independently, thus avoiding the situation that the port assemblies 1 are squeezed and deformed during packaging and transportation, improving the qualified rate of products, and avoiding the impact on production capacity. In addition, the thin iron piercing position of the mold can be reduced, thereby reducing the abnormal situation of the mold caused by the deformation or fracture of the thin iron, and improving the service life and production efficiency of the mold.

[0037] Specifically, as Figure 3 shown, the first clamping portion 101 is configured as a clamping groove, and the second clamping portion 201 is configured as a clamping buckle. Both the clamping groove and the clamping buckle can play a role in clamping and fixing connections. The first clamping portion 101 is configured as a clamping groove, and the second clamping portion 201 is configured as a clamping buckle. In this way, the clamping cooperation between the first clamping portion 101 and the second clamping portion 201 is realized through the clamping cooperation between the clamping groove and the clamping buckle. The structures of the clamping groove and the clamping buckle are simple and convenient for processing and manufacturing. Moreover, the connection method of clamping between the clamping groove and the clamping buckle is simple and convenient, and can make the connection between the top spacer ring 10 and the internal spacer ring 20 firm and reliable.

[0038] Among them, as Figure 3 shown, the clamping buckle is an elastic structural member. The elastic structural member has elastic properties. The clamping buckle is set as an elastic structural member, so that the clamping buckle can undergo elastic deformation. When the clamping buckle is in clamping cooperation with the clamping groove, the clamping buckle can adjust its shape structure through its own elastic deformation and be more conveniently clamped in the clamping groove. In addition, this can also avoid the damage of the clamping buckle caused by the hard cooperation between the clamping buckle and the clamping groove.

[0039] In addition, as Figure 4As shown, the internal spacer ring 20 further includes: an adhesive portion 202, which is adhesively connected to the connection between the buckle and the second main body portion 200, or a chamfer structure is provided at the connection between the buckle and the second main body portion 200. The adhesive portion 202 mainly functions to bond and connect. The adhesive portion 202 is adhesively connected to the connection between the buckle and the second main body portion 200, which can increase the connection strength between the buckle and the second main body portion 200. Or a chamfer structure is provided at the connection between the buckle and the second main body portion 200, which can also increase the connection strength between the buckle and the second main body portion 200. In this way, the safety of the buckle can be improved, the durability of the buckle can be increased, and the connection performance between the buckle and the second main body portion 200 can be improved, so as to ensure that the buckle is not easily damaged during the snap-fit process.

[0040] Of course, as Figure 2 shown, the force direction of the buckle is the first direction, and the snap-together direction of the top spacer ring 10 and the internal spacer ring 20 is the second direction, and the first direction and the second direction are perpendicular to each other. The force direction of the buckle is the first direction, that is, the force direction after the buckle is snap-fitted into the card slot. The first direction refers to the horizontal direction. The snap-together direction of the top spacer ring 10 and the internal spacer ring 20 is the second direction, and the second direction refers to the vertical direction. The first direction and the second direction are perpendicular to each other, which can prevent the snap-together direction of the top spacer ring 10 and the internal spacer ring 20 from being the same as the force direction of the internal spacer ring 20 when installing the top spacer ring 10, resulting in the situation where the buckle of the internal spacer ring 20 is popped open.

[0041] Furthermore, as Figure 3 shown, the top spacer ring 10 is further provided with a first guiding portion 102, and the first guiding portion 102 is provided at one end of the first snap portion 101 adjacent to the internal spacer ring 20. The first guiding portion 102 is a component of the top spacer ring 10. The first guiding portion 102 mainly functions to position and guide, and can also bear a certain amount of lateral pressure to a certain extent, reduce friction and wear, improve the movement smoothness and keep the gap uniformity. The first guiding portion 102 is provided at one end of the first snap portion 101 adjacent to the internal spacer ring 20, so that when the top spacer ring 10 and the internal spacer ring 20 are snap-fitted together, it is convenient for the buckle to better snap into the card slot.

[0042] In addition, as Figure 4 shown, the internal spacer ring 20 is further provided with a second guiding portion 203, and the second guiding portion 203 is provided at one end of the second snap portion 201 adjacent to the top spacer ring 10. The second guiding portion 203 is a component of the internal spacer ring 20. Similarly, the second guiding portion 203 mainly functions to position and guide, and can also bear a certain amount of lateral pressure to a certain extent, reduce friction and wear, improve the movement smoothness and keep the gap uniformity. The second guiding portion 203 is provided at one end of the second snap portion 201 adjacent to the top spacer ring 10, so that when the top spacer ring 10 and the internal spacer ring 20 are snap-fitted together, it is convenient for the buckle to better snap into the card slot.

[0043] It should be noted that, as Figure 3 and Figure 4 shown, the first guiding portion 102 is configured as a chamfer structure, and the second guiding portion 203 is configured as a chamfer structure. Both the first guiding portion 102 and the second guiding portion 203 are configured as chamfer structures, which is convenient for processing and setting. Moreover, the first guiding portion 102 and the second guiding portion 203 can better play the roles of positioning and guiding. When the top spacer 10 and the inner spacer 20 are buckled, it is convenient for the buckle to better snap into the card slot.

[0044] In addition, as Figure 4 shown, the inner spacer 20 includes: a first inner spacer 204 and a second inner spacer 205.

[0046] Optionally, as Figure 4 shown, one of the first installation portion 206 and the second installation portion 207 is an installation protrusion, and the other of the first installation portion 206 and the second installation portion 207 is an installation groove. The installation protrusion is fitted in the installation groove. Both the installation protrusion and the installation groove can play the role of installation and fixation. One of the first installation portion 206 and the second installation portion 207 is an installation protrusion, and the other of the first installation portion 206 and the second installation portion 207 is an installation groove. The installation protrusion is fitted in the installation groove, so that the first installation portion 206 and the second installation portion 207 are installed and matched by setting the installation protrusion in the installation groove, which is convenient for the installation and setting of the first inner spacer 204 and the second inner spacer 205, and can make the setting of the inner spacer 20 more firm and reliable.

[0047] It should be noted that, as Figure 3As shown, an assembly groove 103 is provided on one side surface of the top spacer 10 facing the inner spacer 20.
