DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0033] The rubber cap can be used for the screw-connected positive terminal of the entire vehicle that needs to be separately protected. It is generally used in the connection position of high current in the car, such as the positive pole of the generator and the positive pole of the starter. It is used to protect the positive terminal from short circuit problems caused by foreign objects. However, the existing rubber cap is not waterproof.

[0034] Due to the popularity of new energy hybrid vehicles, new energy hybrid vehicles also include generators and starters. Among them, the generator of new energy hybrid vehicles is located at the rear of the vehicle. The position of the generator is relatively low, which can easily cause the generator to encounter water at the electrode when the vehicle is wading through water, causing a short circuit in the vehicle's power supply line.

[0035] To solve the above technical problems, please refer to Figures 1 to 3 As shown, the first aspect of the present application provides a rubber cap 10 , which can enhance the waterproof capability of the electronic device at the power terminal.

[0036] The rubber cap 10 is applied to electronic equipment with terminal blocks, please refer to Figure 1 As shown, the rubber cap 10 includes a cap head assembly 11 and a cap body 12. The cap head assembly 11 is connected to the electronic device. The cap head assembly 11 has a sealing groove 1111. A sealing ring 1112 is protruded from the groove wall of the sealing groove 1111. The cap body 12 is connected to the cap head assembly 11. The cap body 12 has a wire through hole 121. The wire through hole 121 connects the sealing groove 1111 and the outer space of the cap body 12. The wiring terminal is located in the sealing groove 1111 and is squeezed against the sealing ring 1112.

[0037] It can be understood that the sealing ring 1112 is formed by extending on the groove wall of the sealing groove 1111 along the circumference of the sealing groove 1111. After the sealing ring 1112 and the terminal are squeezed against each other, a closed annular sealing surface is formed between the sealing ring 1112 and the terminal. At this time, the waterproof performance of the electronic device at the terminal is enhanced.

[0038] In addition, it should be understood that the sealing ring 1112 should be supported by elastic material so that the sealing ring 1112 can be deformed and generate elastic potential energy after being squeezed by external force. The elastic potential energy of the sealing ring 1112 ensures the tight fit between the sealing ring 1112 and the terminal.

[0039] Please refer to Figure 1 As shown, in some embodiments of the present application, there are multiple sealing rings 1112, and the multiple sealing rings 1112 are arranged along the depth direction of the sealing groove 1111. The multiple sealing rings 1112 further increase the sealing area between the terminal and the rubber cap 10, that is, further enhance the waterproof performance of the rubber cap 10 on the terminal. The depth direction of the sealing groove 1111 refers to the direction from the notch of the sealing groove 1111 to the bottom of the sealing groove 1111.

[0040] The sealing groove 1111 is used to accommodate the connection terminals of the electronic device. In the embodiment of the present application, there is no limitation on the shape, size, etc. of the sealing groove 1111. The size and shape of the sealing groove 1111 can be set according to the size and shape of the connection terminals.

[0041] The cap body 12 is used to guide and accommodate cables connected to the terminal blocks. In the embodiment of the present application, there is no limitation on the shape, size, and material of the cap body 12, as long as the cap body 12 can accommodate the cables connected to the terminal blocks. For example, the cap body 12 can be set to a tubular structure, and the cables can pass through the cap body 12 and be connected to the terminal blocks.

[0042] Based on the rubber cap 10 of the embodiment of the present application, the cap head assembly 11 is connected to the electronic device. At this time, the wiring terminal of the electronic device is in the sealing groove 1111, and the outer surface of the wiring terminal and the sealing ring 1112 are squeezed against each other to form a sealing surface between the wiring terminal and the sealing ring 1112, thereby enhancing the waterproof performance between the wiring terminal and the sealing ring 1112; the cap body 12 is used to accommodate cables connected to the wiring terminal.

[0043] Please refer to Figure 1 As shown, in some embodiments of the present application, the cap body 12 is at least partially configured as a telescopic structure 122, please refer to Figure 1 As shown, the telescopic structure 122 in the embodiment of the present application is configured as a bellows.

[0044] When the rubber cap 10 is connected to an electronic device, the cable connected to the terminal block needs to be passed through the sealing groove 1111 and the wiring through-hole. At this time, the cap body 12 can shorten its own length through the telescopic mechanism to facilitate the cable to pass through the threading through-hole 121; and the tail end of the cap body 12 is used for fixing and sealing the cable. The cap body 12 can match cables of different lengths through the telescopic structure 122, thereby improving the applicability of the rubber cap 10; wherein, the tail end of the cap body 12 is to the end of the cap body 12 away from the cap head assembly 11.

[0045] Please refer to Figure 1 As shown, in some embodiments of the present application, the cap head assembly 11 includes a cap head 111 and a cap shell 112, the cap head 111 has a sealing groove 1111, and the cap head 111 is connected to the cap body 12; the cap shell 112 is respectively connected to the cap head 111 and the electronic device.

[0046] The cap head 111 has the above-mentioned sealing groove 1111, that is, the cap head 111 is used to accommodate the wiring terminal and form a seal between itself and the wiring terminal. In the embodiments of the present application, there is no limitation on the material, shape and size of the cap head 111. The shape and size of the cap head 111 can be set according to the different adapted wiring terminals; in some embodiments of the present application, the cap head 111 is made of the same material as the cap body 12, and the two are integrally formed.

[0047] The cap shell 112 is used to connect the electronic device to achieve the connection between the rubber cap 10 and the electronic device. It can be understood that the cap shell 112 is made of a hard material, so that the cap shell 112 can have a stable connection with the electronic device.

[0049] In some embodiments of the present application, the cap head 111 includes a main body section and a sealing section that are connected to each other. The outer diameter of the main body section is smaller than the outer diameter of the sealing section to form an axial shoulder between the main body section and the sealing section. The axial shoulder can serve as a force-bearing surface 1113. The sealing groove 1111 is simultaneously opened in the main body section and the sealing section. The sealing groove 1111 is provided with a plurality of sealing rings 1112 on the groove wall of the sealing section, or the sealing single and the main body section are jointly provided with a plurality of sealing rings 1112.

There is a gap between the side wall of the avoidance opening and the side wall of the receiving groove along the radial direction of the receiving groove. The sealing section of the cap head 111 is in the receiving groove, and the main body section of the cap head 111 passes through the avoidance opening and is outside the cap shell 112. The bottom wall of the receiving groove and the force-bearing surface 1113 abut against each other. At this time, after the cap shell 112 is connected to the electronic device, the bottom wall of the receiving groove applies pressure to the force-bearing surface 1113.

[0052] After the first clamping structure and the second clamping structure are connected, the rotation of the cap shell 112 relative to the cap head 111 is restricted, thereby preventing the cap head 111 and the cap body 12 from rotating relative to the cap shell 112 after the cap shell 112 is connected to the electronic device, thereby preventing the cable connected to the terminal from twisting.

[0053] Please refer to Figure 2 as well as Figure 3 As shown, in some embodiments of the present application, the first clamping structure is the first clamping block 1114, the second clamping structure is the first clamping groove 1121, the first clamping block 1114 is in the first clamping groove 1121 and fits into the groove wall of the first clamping groove 1121, the first clamping block 1114 and the second clamping block 1122 have a simple structure, and the limiting effect is reliable after clamping.

[0054] The combined cap head 111 includes a main body section and a sealing section that are interconnected, and the cap shell 112 has a receiving groove and an avoidance opening connected to the bottom wall of the receiving groove. In some embodiments of the present application, a first snap-fit block 1114 is protruding from the surface of the main body section, and the cap shell 112 has a first snap-fit groove 1121, and the first snap-fit groove 1121 is connected to the avoidance opening; it can be understood that the number of the first snap-fit block 1114 and the first snap-fit groove 1121 can be multiple, and the multiple first snap-fit blocks 1114 and the multiple first snap-fit grooves 1121 are evenly spaced along the circumference of the receiving groove.

[0056] Based on the electronic device of the embodiment of the present application, after the rubber cap 10 is connected to the electronic device, the connection terminal of the electronic device is located in the cap head assembly 11, and the outer surface of the connection terminal and the sealing ring 1112 are squeezed against each other to form a sealing surface between the connection terminal and the cap head assembly 11, thereby improving the waterproof performance of the electronic device at the connection terminal.

[0057] The electronic device in the embodiments of the present application can be any electronic device with wiring terminals, such as a generator, a battery, etc.; in particular, for some vehicles with rear-wheel drive motors, due to considerations of the overall structure of the vehicle, the rear-wheel drive motor is positioned below the water-wading surface of the vehicle.

[0061] It can be understood that the number of the card strip and the second card block 1122 can be multiple, and the multiple card strips and the multiple second card blocks 1122 are evenly spaced along the circumference of the sealing groove 1111. When the cap head 111 is connected to the device body, the second card block 1122 pressurizes the card strip to deform the card strip.
