Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a waterproof connector and a motor. Background Technology

[0002] An electrical connector is a key component used to connect electrical devices. Its core function is to transmit current, signals, or data, ensuring reliable communication and energy exchange between components. It typically consists of a plug, a socket, and internal conductors, establishing a conductive path through tight contacts and using insulating materials to isolate different circuits. Electrical connectors are widely used in electronic equipment, communication systems, industrial machinery, automotive electronics, and aerospace, possessing characteristics such as waterproofing, dustproofing, vibration resistance, and electromagnetic interference resistance to adapt to complex environments.

[0003] A waterproof connector for an electric motor is a connector device that is sealed to the motor housing for electrical connection to the internal circuitry of the motor. It mainly consists of an insulating housing sealed to the motor housing by a sealing ring, conductive terminals inserted into the insulating housing, and a grounding terminal. Traditionally, the grounding terminal is typically inserted directly into the insulating housing at one end, while the other end remains suspended for contact with mating components. When the insulating housing is connected to the motor housing on the side facing the motor housing, only the tip of the grounding terminal inserted into the insulating housing contacts the motor housing to improve stability. However, the suspension of the other end of the grounding terminal and the limited positioning of the grounding terminal by the insulating housing mean that the grounding terminal can easily loosen under slight pressure, reducing reliability. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention provides a waterproof connector comprising an insulating shell having an insertion portion, a conductive terminal disposed within the insertion portion, and a grounding terminal. The insulating shell is provided with a fastener for connecting to an electrical device. The grounding terminal comprises an embedded section embedded within the insulating shell, a fastening end connected to the embedded section and exposed on the surface of the insulating shell, and a mating end connected to the embedded section and extending into the insertion portion. The fastening end is electrically connected to the fastener.

[0006] Furthermore, the fastening end has a first through hole through which the fastener passes, and the insulating housing has a second through hole through which the fastener passes; after the fastener passes through the first through hole and the second through hole in sequence, it is fixed to the electrical equipment and electrically connected to the grounding terminal and the electrical equipment.

[0007] Furthermore, the insulating housing has a first surface facing the electrical equipment and a second surface opposite to it, and the fastening end is embedded on the second surface.

[0008] Furthermore, the embedded section includes a straight section extending horizontally from the fastening end; the straight section includes a first section extending from the fastening end in a first direction and a second section extending from the first section in a second direction perpendicular to it.

[0010] Furthermore, the mating end includes an embedding section extending from the fifth section along the insertion direction and used for embedding within the insulating housing, and a mating section extending from the embedding section along the insertion direction into the insertion portion.

[0011] Furthermore, the embedded section protrudes backwards on both sides of its width to form a shoulder.

[0012] Furthermore, a through hole connecting to the fourth segment is provided on the first surface at the position corresponding to the fourth segment along the insertion direction.

[0013] Furthermore, a sealing area is formed on the first surface inside the fastener by a sealing ring, and a first mounting area and a second mounting area are formed on the insulating housing corresponding to the sealing area; the conductive terminal includes a first terminal inserted into the first mounting area along the insertion direction and a second terminal inserted into the second mounting area along the insertion direction, and a water-blocking portion is provided on the first surface along the insertion direction toward the side away from the second surface, surrounding the second mounting area.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] Please see Figures 2 to 10 The waterproof connector of this utility model includes an insulating shell 1, conductive terminals 2 disposed within the insulating shell 1, grounding terminals 3 disposed within the insulating shell 1, and fasteners 4 disposed on the insulating shell 1. The insulating shell 1 is used to support and protect the conductive terminals 2 and the grounding terminals 3. The conductive terminals 2 are used for transmitting electrical signals with a complementary connector, and the grounding terminals 3 are used to allow current to flow into the ground to ensure electrical safety. The fasteners 4 are used to connect the insulating shell 1 to the electrical equipment. It should be noted that the electrical equipment includes various electronic devices such as motors.

[0031] Please see Figures 2 to 5 , Figure 7 In this embodiment, the insulating shell 1 is made of insulating material such as plastic. The insulating shell 1 includes a main body 11 and an insertion part 12. For ease of installation, both the main body 11 and the insertion part 12 are rectangular parallelepiped structures, and the length of the insertion part 12 is less than the length of the main body 11 and the width of the insertion part 12 is less than the width of the main body 11.

[0032] In this embodiment, the main body 11 has a first surface 131 facing the electrical equipment and a second surface 132 distributed opposite to the first surface 131. The first surface 131 and the second surface 132 are distributed on both sides of the main body 11 along its thickness direction. A sealing ring 19 is connected to the first surface 131, inside the fastener 4. The sealing ring 19 forms a sealing area 14 on the first surface 131. When the first surface 131 is attached to the electrical equipment, the sealing ring 19 is used to tightly adhere to the electrical equipment and maintain the sealing of the sealing area 14. A first mounting area 141 and a second mounting area 142 are formed on the main body 11 at positions corresponding to the sealing area 14, along the thickness direction of the main body 11. In this embodiment, the thickness direction of the main body 11 is defined as the insertion direction, the width direction of the main body 11 is defined as the first direction, and the length direction of the main body 11 is defined as the second direction, wherein both the first and second directions are horizontal. The conductive terminal 2 is divided into two parts. One part is inserted into the first mounting area 141 along the insertion direction, and the other part is inserted into the second mounting area 142 along the insertion direction. During assembly, the conductive terminal 2 can be integrally injection molded into the insulating housing 1 during the injection molding process, thereby improving the bonding strength and stability between the conductive terminal 2 and the insulating housing 1. In this embodiment, the electrical device has a structure corresponding to the second mounting area 142 that connects to the internal cavity of the electrical device. The portion of the first surface 131 other than the second mounting area 142 is all fitted to the outer shell of the electrical device. The sealing ring 19 ensures that external moisture and dust do not enter the internal cavity of the electrical device. To further improve the installability of the electrical equipment's internal cavity, a water-blocking portion 15 is provided on the first surface 131, located around the periphery of the second mounting area 142, extending away from the second surface 132 along the insertion direction. The water-blocking portion 15 is arranged around the second mounting area 142 and is used to penetrate into the internal cavity of the electrical equipment. The cooperation between the water-blocking portion 15 and the internal cavity wall of the electrical equipment forms a second layer of water-blocking structure to enhance the waterproof effect. The cavity surrounded by the water-blocking portion 15 is filled with glue to fix the conductive terminal 2 and ensure sealing.

[0033] In this embodiment, the insertion portion 12 extends from the middle of the second surface 132 of the main body 11 along the thickness direction of the main body 11 toward the side away from the first surface 131. The insertion portion 12 is adapted to the structure of the complementary connector so that it can be inserted into the complementary connector for complementarity. Threaded holes 161 are provided on both sides of the main body 11, and copper nuts 162 are screwed into the threaded holes 161 to provide low-voltage protection for the entire waterproof connector. This allows for rapid and stable current cutoff in the event of a short circuit or overload in the waterproof connector, thus providing important safety protection for the electrical system.

[0034] Please see Figures 2 to 5 , Figures 7 to 10 In this embodiment, the conductive terminal 2 is made of a conductive material such as copper. The conductive terminal 2 includes a first terminal 21 inserted in the first mounting area 141 along the insertion direction and a second terminal 22 inserted in the second mounting area 142 along the insertion direction. The first terminal 21 and the second terminal 22 are respectively used to connect with different complementary terminals and cables. The first terminal 21 and the second terminal 22 can be used to transmit large current and small current respectively, or the first terminal 21 and the second terminal 22 can be used to connect power lines and control lines respectively to realize current transmission and electrical signal transmission.

[0035] In this embodiment, the first terminal 21 includes an arc-shaped first wire-holding segment 211, a first connecting segment 212 bent from the side of the arched portion of the first wire-holding segment 211, a first fastening segment 213 extending from the first connecting segment 212 along the insertion direction, and a first plug-in segment 214 extending from the first fastening segment 213 along the insertion direction toward the side away from the first connecting segment 212. The two sides of the first wire-holding segment 211 are curved toward the side away from the first plug-in segment 214 for connection with the corresponding cable of the electrical equipment; the opposite two sides of the first fastening segment 213 are each provided with a first protrusion 215 for passing through the body 11 and abutting against the inner wall of the body 11. A first insertion cavity 17 is formed in the first installation area 141 along the insertion direction, penetrating the main body 11. The first insertion cavity 17 has a first cavity segment 171 penetrating the first surface 131 and the second surface 132, a second cavity segment 172 connecting the first cavity segment 171 and penetrating the second surface 132, and a third cavity segment 173 penetrating the insertion part 12 and connecting the second cavity segment 172. The first wire-holding segment 211 and the first connecting segment 212 are located in the first cavity segment 171, and there is a large gap between the first cavity segment 171 and the first wire-holding segment 211 and the first connecting segment 212, so that glue can be filled into the first cavity segment 171 if needed, or the cavity can be kept empty as needed. The first fastening segment 213 and the second cavity segment 172 are adapted to each other, and the first fastening segment 213 is inserted and abutted in the second cavity segment 172. The first insertion segment 214 is located within the third cavity segment 173 and has a large gap between it and the inner wall of the third cavity segment 173, so that the corresponding structure of the complementary fastener 4 can be inserted into the third cavity segment 173. In this embodiment, at least one first terminal 21 is provided, and the first insertion cavities 17 are arranged to match it one by one. When two first terminals 21 are provided, two corresponding second insertion cavities 18 are also provided, both located within the first mounting area 141.

[0036] In this embodiment, the second terminal 22 includes an arc-shaped second wire-holding segment 221, a second connecting segment 222 extending from one side of the first wire-holding segment 211 along the insertion direction, a second fastening segment 223 extending from the second connecting segment 222 along the insertion direction away from the second wire-holding segment 221, and a second insertion segment 224 extending from the second fastening segment 223 along the insertion direction away from the second connecting segment 222. The two sides of the second wire-holding segment 221 are curved in a second direction. The second fastening segment 223 is wider than the second connecting segment 222 and the second insertion segment 224, and the second fastening segment 223 and the second insertion segment 224 form an L-shape. On opposite sides of the second fastening segment 223, a second protrusion is provided facing away to abut against the inner wall of the body 11 after insertion into the body 11. The second insertion segment 224 is used to cooperate with the complementary terminal to achieve electrical connection. A second insertion cavity 18 is formed in the second mounting area 142 at a position corresponding to the second terminal 22, extending along the insertion direction. The second insertion cavity 18 penetrates the main body 11 and the insertion part 12 along the insertion direction. The second insertion cavity 18 includes a fourth cavity segment 181 extending through the first surface 131 along the insertion direction, a fifth cavity segment 182 connecting the fourth cavity segment 181 and extending through the second surface 132 along the insertion direction, and a sixth cavity segment 183 connecting the fifth cavity segment 182 and extending through the insertion part 12 along the insertion direction. The number of second insertion cavities 18 is the same as the number of second terminals 22. The second terminals 22 are set to at least one, and in this embodiment, three. The corresponding second insertion cavities 18 are set to three. The sixth cavity segments 183 are interconnected. The second wire-holding segment 221 and the second connecting segment 222 are both located outside the insulating housing 1 for extending into the internal cavity of the electrical equipment. The second fastening segment 223 is inserted into the fourth cavity segment 181 and abuts against the inner wall of the fourth cavity segment 181 through the second protrusion. The second insertion segment 224 passes through the fifth cavity segment 182 and is located in the sixth cavity segment 183, and there is a gap between the inner wall of the sixth cavity segment 183 and the second insertion segment 224 to allow the corresponding structure of the complementary connector to pass through it. The second connecting segment 222 and part of the second wire-holding segment 221 are located in the internal cavity of the water-blocking part 15 and are sealed therein with glue. It should be noted that, in order to make the complementary connector more stable when it is inserted into each of the third cavity 173 and the sixth cavity 183, a shallow groove 121 is provided on the side of the insertion part 12 away from the main body 11, which connects the third cavity 173 and the sixth cavity 183. The shallow groove 121 forms a flush plane outside the groove of each of the third cavity 173 and the sixth cavity 183, so as to increase the contact surface and limit the insertion depth when the corresponding structure of the complementary connector is inserted therein.

[0037] Please see Figures 4 to 7 and Figure 10In this embodiment, the grounding terminal 3 includes a recessed section 31 embedded in the insulating housing 1, a fastening end 32 connected to the recessed section 31 and exposed on the surface of the insulating housing 1, and a mating end 33 connected to the recessed section 31 and extending into the insertion portion 12. The fastening end 32 is electrically connected to the fastener 4, and the fastening end 32 is fixed when the fastener is fastened to the insulating housing 1, so that the fastening end 32 is locked and more secure. The fastener 4 ensures stability between the equipment housing. The recessed section 31 cannot shake because it is embedded inside the insulating housing 1, and the stability is greatly improved. The mating end 33 extends into the insertion portion 12 and into the sixth cavity section 183. After the complementary connector mates with the insertion portion 12, the corresponding part of the complementary connector can easily mate with the mating end 33.

[0038] In this embodiment, the embedded section 31 includes a straight section 31a extending horizontally from the fastening end 32 and a bent section 31b bending from the second section 312. The mating end 33 is connected to the end of the bent section 31b away from the fastening end 32. The straight section 31a includes a first section 311 extending from the fastening end 32 in a first direction and a second section 312 extending from the first section 311 in a second direction. The first section 311 lengthens the straight section 31a, and at the same time, the force exerted on the bent section 31b and the mating end 33 during use is dispersed by the first section 311, greatly reducing the pressure acting on the fastening end 32, thereby improving the stability of the service life of the fastening end 32. The second section 312 maintains a basic connection with the bent section 31b. The bent section 31b includes a third section 313 extending from the second section 312 along the insertion direction toward the first surface 131, a fourth section 314 extending from the third section 313 along the second direction toward the side away from the straight section 31a, and a fifth section 315 extending from the fourth section 314 toward the second surface 132, so that the bent section 31b has an overall U-shaped structure. By bending, the width of the entire grounding terminal 3 embedded section 31 in the insertion direction is reduced, which allows the insulating shell 1 to be thinned during injection molding, thereby reducing the material used in the insulating shell 1 and reducing costs. The entire embedded section 31 is located within the main body 11, and the mating end 33 is connected to the fifth section 315.

[0039] In this embodiment, the fastening end 32 has a ring-shaped structure with a first through hole 321 through which the fastener 4 passes. After passing through the first through hole 321, the fastener 4 cooperates with the main body 11 and the electrical equipment housing to connect the insulating housing 1 and the electrical equipment, and to fix the fastening end 32 to the insulating housing 1 and the electrical equipment, thereby fixing the grounding terminal 3 to the electrical equipment. A through groove 112 is recessed on the second surface 132 of the main body 11 at the position corresponding to the fastener 4. The through groove 112 is circular and its depth is the same as the thickness of the fastening end 32. Therefore, the fastening end 32 is located in the through groove 112 and is embedded in the second surface 132 after the insulating housing 1 is injection molded.

[0040] In this embodiment, the mating end 33 includes an embedding section 331 extending from the fifth section 315 along the insertion direction and for being embedded in the insulating housing 1, and a mating section 332 extending from the embedding section 331 along the insertion direction into the insertion portion 12. The embedding section 331 has shoulders 333 protruding backwards along its two sides to increase the bonding force between the mating end 33 and the insulating housing 1. The embedding section 331 is located within the main body 11. In this embodiment, the mating section 332 faces the sixth cavity section 183 along the insertion direction and penetrates into the sixth cavity section 183. Therefore, the grounding terminal 3 is also located within the second mounting area 142.

[0041] It should be noted that, in order to ensure that the grounding terminal 3 remains stable and does not float with the injection liquid during the integral injection molding process of the insulating housing 1, a process hole is reserved on the injection mold at the position corresponding to the grounding terminal 3. A ejector pin-like structure is inserted into the process hole to hold the grounding terminal 3 in place, preventing the lower limit of the grounding terminal 3 from moving during the injection molding process. After the insulating housing 1 is formed, the ejector pin is removed, and a through hole 111 is formed on the first surface 131 at the position corresponding to the ejector pin. The through hole 111 corresponds to the position of the fourth section 314 and connects to the fourth section 314 along the insertion direction.

[0042] Please see Figures 1 to 7The fastener 4 is provided in at least two locations; in this embodiment, four fasteners 4 are provided and located at the four corners of the main body 11. At each of the four corners of the main body 11 of the insulating housing 1, corresponding to the four fasteners 4, a second through hole 113 is provided for the fastener 4 to pass through. Each second through hole 113 penetrates the first surface 131 and the second surface 132 of the main body 11 along the insertion direction. After the fastener 4 passes through the first through hole 321 of the fastening end 32 and the second through hole 113 on the main body 11, it connects to the electrical equipment, and the fastener 4 presses the fastening end 32 against the insulating housing 1 to lock the grounding terminal 3. In this embodiment, the fastener 4 includes a bolt 41, a washer 42, and a gasket 43. A groove 114 is provided on the second surface 132 of the main body 11 at the position corresponding to the washer 43 and the washer 42. The groove 114 is connected to the through slot 112. The bolt 41 passes through the washer 43, the washer 42, the first through hole 321, and the second through hole 113 in sequence to fasten the main body 11 and realize the connection between the insulating shell 1 and the electrical equipment.

[0043] Please see Figure 1 In this utility model, an electric motor is provided, which includes an electric motor housing 511 and a waterproof connector connected to the electric motor housing 511.

[0044] The assembly and operation of one embodiment of the waterproof connector and motor of this utility model are as follows: During assembly, the first terminal 21, the second terminal 22, and the grounding terminal 3 are all inserted into the mold using in-mold injection molding. The sealing ring 19 can also be inserted into the mold. Liquid plastic is injected into the mold until it cools and solidifies. After this process, the first terminal 21, the second terminal 22, and the contact piece have stronger bonding force, and the holding force and waterproof effect are improved. Then, the copper nut 162 and the fastener 4 are sequentially connected to the main body 11, so that the first wire segment 211 and the second wire segment 221 are connected to the corresponding cables. After the surface 131 and the inner cavity of the water-blocking part 15 are filled with glue, the insulating shell 1 is connected to the motor housing by the fastener 4, thereby achieving the waterproof effect of the sealing area 14 through the glue and the sealing ring 19. In use, the insertion part 12 is oriented towards the complementary connector, so that the corresponding structure of the complementary connector is sleeved on the insertion part 12 and the corresponding structure is inserted into the third cavity section 173 and the sixth cavity section 183. The corresponding complementary terminals of the complementary connector are respectively inserted and cooperated with the first insertion section 214 and the second insertion section 224 to realize the transmission of electrical signals. The grounding terminal 3 is also connected to the corresponding structure of the complementary connector.

[0045] Compared with the prior art, the waterproof connector and motor of this utility model improve the stability of the bonding force by integrally injection molding the grounding terminal 3 and the insulating shell 1, and improve the reliability and firmness by cooperating with the fastener 4 and the grounding terminal 3 to prevent the grounding terminal 3 from shaking; the fastening end 32 embedded on the second surface 132 ensures that it cooperates with the fastener 4 while avoiding affecting the use of the insulating shell 1; the straight section 31a and the bent section 31b increase the contact area between the grounding terminal 3 and the insulating shell 1 to improve the bonding force, reduce the negative impact of the fastening end 32 and the thickness of the entire waterproof connector, and save costs and insulation material.
