Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] To dissipate heat, automotive components located inside the car have corresponding oil pipes or oil chambers installed on their exteriors. The medium flowing through these oil pipes or chambers carries away the heat generated by the automotive components during operation.

[0030] However, when automotive components are encased in oil lines or oil chambers, electrical connectors are needed to connect the internal and external circuitry of these components. Current electrical connectors use a mating male and female connector configuration. To ensure the sealing performance of these connectors, their complex structure and difficulty in installing them into the internal and external wiring of automotive components make them problematic.

[0031] To address the aforementioned problems, this specification provides an electrical connector that aims to provide a novel electrical connector capable of solving the problems described above. Please refer to... Figures 1 to 6 The electrical connector includes:

[0032] The main housing 10 is arranged radially. The two ends of the main housing 10 in the radial direction are respectively provided with a first port 11 and a second port 12. An internal space through the main housing is formed between the first port 11 and the second port 12. A connecting wing plate 20 is integrally formed on the main housing 10. The connecting wing plate 20 protrudes from the outer surface of the main housing 10 in the radial direction and is used to dock with the connection position.

[0033] In this embodiment, the main housing 10, which is the main body of the electrical connector, can be made of materials such as plastic, which ensures the structural strength of the main housing 10 while also giving it a certain degree of deformability.

[0034] The main housing 10 is a radially arranged housing structure. Specifically, the radial cross-section of the main housing 10 can be cylindrical, conical, rectangular, etc. In this application, the specific shape of the radial cross-section of the main housing 10 is not limited. In this embodiment, the radial cross-section of the main housing 10 is rectangular, which facilitates the forming and manufacturing of the main housing 10.

[0035] In this embodiment, a connecting wing plate 20 protrudes from the outer surface of the main housing 10. The connecting wing plate 20 is integrally formed on the main housing 10 and protrudes along the radial direction of the main housing 10. The connecting wing plate 20 is used to mate with the connection position. For example, the connecting wing plate 20 is mated with the gearbox housing to realize the installation and positioning of the electrical connector. The connecting wing plate 20 is provided with mounting holes, through which the connecting wing plate 20 can be mated with the corresponding connection position.

[0036] In this embodiment, a bushing 30 is provided at the mounting hole of the connecting wing plate 20. The bushing 30 protects the mounting hole and prevents it from being damaged. Specifically, the bushing 30 can be made of materials such as stainless steel to ensure that the bushing 30 has sufficient structural strength.

[0037] In this embodiment, the main housing 10 is also provided with a positioning protrusion 16 for assisting in the installation of the electrical connector. The positioning protrusion 16 can assist in positioning the electrical connector during the docking of the connecting wing plate 20.

[0038] The first port 11 and the second port 12 are two ports arranged opposite to each other in the inner space. A wire can be placed through these two ports. The wire includes a first wire and a second wire. The first wire is the external wire part, and the second wire can be the internal wire part of the motor. There are several crimp terminals 40 in the inner space for connecting the second wire and the first wire. Each crimp terminal 40 is used to connect one first wire and one second wire. The first wire extends out of the first port, and the second wire extends out of the second port.

[0039] The inner space is provided with a seal 50 and a sealing sleeve 60 to block the first port 11 and the second port 12. The seal 50 is filled into the inner space, and the sealing sleeve 60 is inserted into the inner space. The seal 50 and the sealing sleeve 60 are in contact with each other. All the crimp terminals 40 are located at the sealing sleeve 60. The seal 50 is used to seal the first wire, and the sealing sleeve 60 is used to seal the first wire, the crimp terminals 40, and the second wire. The seal 50 can be made of a material with excellent sealing performance, such as epoxy resin.

[0040] With the sealing cooperation of seal 50 and sealing sleeve 60, the leakage of internal oil from components such as the gearbox to the outside and the entry of external water, oil, and other impurities into the components can be prevented.

[0041] Specifically, the inner space includes a first inner space 13 and a second inner space 14 that are interconnected. The first inner space 13 is located near the first port 11, and the second inner space 14 is located near the second port 12. The sealing element 50 is filled into the interior of the first inner space 13, and the sealing sleeve 60 is inserted into the second inner space 14.

[0042] In this embodiment, the sealing sleeve 60 is provided with a plurality of placement slots 61. The first wire and the second wire are both placed in the placement slots. That is, each placement slot 61 is a space for placing a wire. Each placement slot 61 has a first fixing protrusion 62 and a third fixing protrusion 64 protruding from the placement slot 61 at both ends. A second fixing protrusion 63 protruding from the placement slot 61 is provided between the first fixing protrusion 62 and the third fixing protrusion 64. The crimp terminal 40 is located between the first fixing protrusion 62 and the second fixing protrusion 63.

[0043] In this embodiment, the main housing 10 is provided with an auxiliary hole 17 on the side near the second port 12. The auxiliary hole 17 can also assist in the installation of the electrical connector.

[0044] In this embodiment, the outer surface of the main housing 10 is provided with a sealing ring mounting groove that surrounds the main housing 10 in the radial direction, and a sealing ring 70 is installed in the sealing ring mounting groove.

[0045] The sealing ring 70 further prevents the oil inside the gearbox and other components from flowing out to the outside, and prevents external water, oil and other impurities from entering the components.

[0046] Preferably, the sealing ring 70 is made of AEM rubber, a black solid rubber with good elasticity and mechanical strength. At room temperature, its hardness is typically 60-90 Shore A, and it gradually softens as the temperature increases. AME rubber exhibits excellent oil and corrosion resistance, and can operate stably in various oil, solvent, and acid / alkali environments.

[0047] In this embodiment, a plurality of limiting holes 16 are arranged in an array on the outer surface of the main housing 10 and along the radial direction of the main housing 10. The limiting holes 16 are located on both sides of the sealing ring 70, that is, two rings of limiting holes 16 are provided on the outer surface of the main housing 10. When the electrical connector is installed, the limiting holes 16 can be used to position and cooperate with various installation limiting components provided at the installation position. With the cooperation of the connecting wing plate 20 and the limiting holes 16, the electrical connector is prevented from detaching.

[0048] During assembly, the insulating shells at the ends of the first and second wires are first peeled off. Then, the connection between the first and second wires is completed through the crimp terminal 40. Next, the wires and the crimp terminal 40 are installed on the sealing sleeve 60 through the placement groove 61, the first fixing protrusion 62, and the second fixing protrusion 62. The sealing sleeve 60 can both place each wire and stably support the wires. Then, the first wire is passed through the second port 12 and the first port 11 in sequence, and the sealing sleeve 60 is fixed by the insertion and engagement between the second inner space 14 and the sealing sleeve 60. In this way, the sealing sleeve 60 can seal the first wire, the crimp terminal 40, and the second wire. Immediately afterwards, the sealing element 60 is directly potted to seal the entire first inner space. In this way, the sealing element 50 can seal the first wire. Then, the sealing ring 70 is installed on the main housing 10. After confirming that the electrical connector can pass the airtightness test, the electrical connector assembly is completed.

[0049] In this embodiment, the electrical connector further includes a connector 80 that engages with the sealing sleeve 60. The connector 80 includes a cover 81, a pressing protrusion 83 disposed on the cover 81 that engages with the placement groove 61 and is used to press the second wire, and a buckle 82 disposed on the cover 81. The sealing sleeve 60 has a groove 65 that engages with the buckle 82 at one end near the third fixing protrusion 64.

[0050] Specifically, there are two connectors 80 that mate with the sealing sleeve 60, so that the sealing sleeve 60 can be clamped by the connectors 80 from both directions. Unlike electrical connectors in the prior art, this electrical connector first passes the wire through the inner space of the main housing 10, and then directly fills the first inner space 13 with the sealing element 50 to seal and fix the first wire. There is no need to leave a hole in the sealing element 50 for the wire to pass through. The second wire and the crimp terminal 40 used to connect the first and second wires are sealed and fixed by the sealing sleeve 60 that mates with the second inner space 14. The sealing sleeve 60 can not only hold each wire, but also stably support the wire. The electrical connector 80 can prevent the wire from easily sliding or shifting, and the wire will not fall off the electrical connector.

[0051] To address the aforementioned problems, this specification provides a connecting device comprising a first wire, a second wire, and as described above. Figures 1 to 6 The described electrical connector has a first wire that is electrically connected to a second wire. The first wire is an external wire, and the second wire can be an internal wire on a motor. This connection device enables quick connection of internal and external wires of automotive components. At the same time, the electrical connector in this connection device can prevent oil from flowing out of the automotive components or water, liquids, and other impurities from entering the automotive components, thus providing good sealing performance.

[0052] The present invention relates to an electrical connector and a connecting device. The connector first allows the wire to pass through the inner space of the main housing 10, and then directly seals and fixes the first wire by filling the first inner space 13 with a sealing element 50. This eliminates the need to pre-leave a hole in the sealing element 50 for the wire to pass through. The second wire and the crimp terminal 40 for connecting the first and second wires are sealed and fixed by a sealing sleeve 60 that inserts into the second inner space 14. The sealing sleeve 60 not only accommodates the wires but also stably supports them. The electrical connector 80 prevents the wires from... The cable can slide and shift easily without falling off the electrical connector. With the sealing cooperation of the seal 50 and the sealing sleeve 60, it can prevent the oil inside the gearbox and other components from flowing out to the outside and prevent external water, oil and other impurities from entering the components. The electrical connector and the connecting device that uses the electrical connector can quickly connect the internal and external cables of the automotive components. At the same time, the electrical connector in the connecting device can prevent the oil inside the automotive components from flowing out to the outside or the water, liquid and other impurities from entering the automotive components, providing good sealing performance.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
