Description

Technical Field

[0001] This invention relates to the field of connector technology, and more particularly to an electrical connector that facilitates cable assembly. Background Technology

[0002] Chinese invention patent CN105391231B discloses a female connector for an electric motor. The electric motor includes a circuit board for connecting a coil to a stator, a male connector formed on a portion of the outer periphery of the circuit board, and a housing for housing the circuit board. The male connector protrudes from an opening formed in the housing, and the female connector connected to a cable can be fitted into the male connector. The connector is characterized by having a female contact member connected to the cable and fitted into the male connector member, a connector housing for housing the female contact member, and a cover for housing the connector housing and fixed to the housing of the electric motor. The connector housing is held in the cover in a manner movable along a plane orthogonal to the direction of fitting with the male connector member.

[0003] In this female connector structure, the direction in which the female contact connects to the cable is perpendicular to the direction in which the female contact engages with the male connector. When connecting the cable to this female connector, the cable must first be passed through the cylindrical part of the connector housing and connected to the female contact. As the female contact is installed into the connector housing, the cable needs to be pulled outwards and straightened. The cable pulling and straightening operations during assembly are cumbersome and can easily lead to electrical connection failure due to pulling. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and to propose an electrical connector that facilitates cable assembly.

[0005] The technical solution adopted in this invention is as follows: An electrical connector, comprising:

[0006] A terminal module includes an insulating base and a plurality of conductive terminals fixed on the insulating base, each conductive terminal including a mating portion and a tail portion;

[0007] A cable, which is electrically connected to the tail of the conductive terminal;

[0008] An outer casing includes an upper casing and a lower casing joined together vertically. The upper casing includes a first main body and an upper half of the cable outlet extending rearward from the first main body. The interior of the first main body has a receiving cavity for accommodating the insulating base. The lower surface of the first main body and the lower surface of the upper half of the cable outlet form a first mating surface surrounding the receiving cavity. The lower casing includes a second main body and a lower half of the cable outlet extending rearward from the second main body. The interior of the second main body has a vertically penetrating opening. The upper surface of the second main body and the upper surface of the lower half of the cable outlet form a second mating surface surrounding the opening. A sealing ring is provided between the first mating surface and the second mating surface. The upper half of the cable outlet and the lower half of the cable outlet form a cable outlet through which the cable passes. The mating portion of the conductive terminal is exposed outward through the opening, wherein the mating direction of the mating portion is set at 90 degrees to the cable outlet.

[0009] Compared with the prior art, the present invention has at least the following advantages: In the electrical connector of the present invention, the outer shell adopts a combined structure of an upper shell and a lower shell spliced ​​together, which allows the cable to be connected to the conductive terminal module and then installed into the upper shell first, and then the lower shell to be assembled into the upper shell. For the electrical connector of the present invention, where the mating direction of the mating part is set at 90 degrees to the cable passing direction, this combined structure of the present invention eliminates the need to pull the cable during the assembly process, thus eliminating the pulling and threading process during the assembly of traditional electrical connector structures and fundamentally improving assembly efficiency. At the same time, the sealing ring provided between the mating surfaces of the upper shell and the lower shell can prevent external water droplets from entering the interior of the outer shell through the mating surface between the upper shell and the lower shell, thus playing a role in waterproof sealing.

[0028] The preferred embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] See Figure 1 In this preferred embodiment, the electrical connector 100 can be mated with another mating connector 200. The mating connector 200 can be fixed to a motor (not shown), and the electrical connector 100 is connected to a cable 2. The electrical connector 100, as an electrical connector at the end of a wire harness, can be detachably connected to the mating connector 200 to transmit power and signals. Preferably, the mating connector 200 has an upwardly protruding locking piece 201 on each side, and each locking piece 201 has a locking protrusion 2011 at its center, protruding outwards from the vertical plane of the locking piece 201. The horizontal sides of the locking protrusion 2011 bridge the locking piece 201. The electrical connector 100 preferably has a locking structure 4 for correspondingly locking with the locking protrusion 2011 of the mating connector 200.

[0030] For ease of description, the direction in which the electrical connector 100 mates with the mating connector 200 is defined as the up-down direction, wherein the mating connector 200 is located below the electrical connector 100; the direction in which the cable 2 exits is defined as the front-back direction.

[0031] See next Figures 2 to 5 The preferred embodiment of the electrical connector 100 mainly includes a terminal module 1, a cable 2 electrically connected to the terminal module 1, a housing 3 for housing the terminal module 1, a locking structure 4 movably pivotally connected to the housing 3, a locking member 5 sleeved on the cable 2, and a cap 6 sleeved on the outer periphery of the cable 2 and screwed together with the housing 3.

[0032] like Figure 5As shown, the terminal module 1 mainly includes an insulating base 11 and a plurality of conductive terminals 12 fixed on the insulating base 11. The insulating base 11 is preferably integrally injection molded from insulating material. The insulating base 11 has a plurality of terminal cavities 111 extending in the vertical direction. The plurality of conductive terminals 12 are respectively fixed in the terminal cavities 111 of the insulating base 11. Figure 4 Each conductive terminal 12 includes a mating portion 121 at the lower end and a tail portion 122 at the upper end.

[0033] Continue reading Figure 4 and Figure 5 The cable 2 includes multiple conductors 21 and an outer sheath 22 covering these conductors 21. The front ends of these conductors 21 extend from the outer sheath 22 and are electrically connected to the tail 122 of the conductive terminal 12. A circumferentially protruding retaining ring 23 is injection molded onto the outer sheath 22. The number of these conductors 21 can be adapted to the number of conductive terminals 12 in the terminal module 1.

[0034] See also Figures 4 to 8 The outer casing 3 comprises an upper casing 31 and a lower casing 32 joined together. The upper casing 31 and the lower casing 32 are first molded separately, and then joined together to form the complete outer casing 3. In this preferred embodiment, the upper casing 31 and the lower casing 32 are fastened together by a plurality of screws 33. A sealing ring 34 is also provided between the upper casing 31 and the lower casing 32 to form a sealed connection.

[0035] Main references Figures 5 to 7 The upper housing 31 includes a first body 311 and an upper half cable outlet tube 312 extending rearward from the first body 311. The upper housing 31 is preferably integrally injection molded from plastic.

[0036] The first main body 311 is generally a rectangular structure with an open bottom and a hollow interior. The first main body 311 has a pivot structure 3115 on each side for the locking structure 4 to pivotally connect. In this embodiment, the pivot structure 3115 is specifically a pivot groove that is recessed inward. The front outer surface of the first main body 311 has two locking protrusions 3116 that protrude forward.

[0037] The first main body 311 has a receiving cavity 3111 recessed from the lower surface. The receiving cavity 3111 is used to receive the insulating base 11 of the terminal module 1. The receiving cavity 3111 is provided with a latching arm 3112 for securing the insulating base 11. The latching arm 3112 extends elastically downward from the top surface of the receiving cavity 3111 near the two sides.

[0038] Preferably, the lower surface of the first body 311 is further provided with a plurality of downwardly protruding positioning posts 3113, which are distributed around the periphery of the receiving cavity 3111. In addition, the lower surface of the first body 311 is also provided with a first screw hole 3114 for the screw 33 to be locked.

[0039] The vertical cross-section of the upper half of the cable outlet 312 along the vertical direction is preferably semi-circular, and its arc opening is set downward. The upper half of the cable outlet 312 extends rearward from the rear side wall of the first body 311, and the interior of the upper half of the cable outlet 312 is connected to the receiving cavity 3111 inside the first body 311.

[0040] The lower surfaces of the first main body 311 and the upper half of the cable outlet tube 312 are preferably flush, forming a first mating surface 310. The first mating surface 310 surrounds the receiving cavity 3111 in the portion of the first main body 311 and extends in the front-rear direction in the portion of the upper half of the cable outlet tube 312, forming a first opening 3102 at its rear end. Preferably, a channel 3104 is formed on the first mating surface 310 surrounding the receiving cavity 3111 within it.

[0041] In this preferred embodiment, the sealing ring 34 is made of liquid silicone and is formed in the groove 3104 of the first mating surface 310 of the upper housing 31 by liquid silicone injection molding. Therefore, the sealing ring 34 can be tightly bonded to the upper housing 31 without relative positional displacement. The sealing ring 34 extends slightly downward beyond the groove 3104.

[0042] The sealing ring 34 extends continuously along the first mating surface 310. The sealing ring 34 includes a surrounding section 341 located on the lower surface of the first body 311 and enclosing the receiving cavity 3111 therein, and two straight extension sections 342 extending rearward from the surrounding section 341 and spaced apart by a distance. The two straight extension sections 342 are located on the lower surface of the upper half of the cable outlet 312 and extend along the length of the upper half of the cable outlet 312 to the first opening 3102 at the rear end of the upper half of the cable outlet 312. The surrounding section 341 and the straight extension sections 342 extend continuously in the horizontal direction in an uninterrupted structure.

[0043] Furthermore, in this preferred embodiment, the inner wall of the upper half of the cable outlet 312 is also provided with a first sealing member 35. The first sealing member 35 is preferably located near the rear end of the upper half of the cable outlet 312 (in this preferred embodiment, at the rear end). The first sealing member 35 extends circumferentially along the inner wall of the upper half of the cable outlet 312, forming a vertically placed semi-circular arc. The front sides of both ends of the first sealing member 35 are respectively connected to the two straight extension segments 342 of the sealing ring 34, thereby forming a closed structure with the sealing ring 34.

[0044] The first seal 35 is preferably formed together with the sealing ring 34 on the upper housing 31 by a liquid silicone injection molding process.

[0045] See Figure 5 , Figure 6 and Figure 8 The lower housing 32 includes a second body 321 and a lower half cable outlet tube 322 extending rearward from the second body 321. The lower housing 32 is preferably integrally injection molded from plastic.

[0046] The second main body 321 is generally rectangular in shape, with a through opening 3211 inside. The upper surface of the second main body 321 has multiple positioning holes 3212, distributed around the periphery of the opening 3211, corresponding to positioning posts 3113 on the first main body 311. The second main body 321 also has multiple through second screw holes 3213, through which screws 33 are inserted.

[0047] Combination Figure 3 The second main body 321 is provided with a locking groove 3214 that runs vertically through each side of the opening 3211. The locking groove 3214 allows the locking structure 4 to extend into it and rotate.

[0048] Continue reading Figure 5 , Figure 6 and Figure 8 The vertical cross-section of the lower half of the cable outlet 322 is approximately semi-circular, with its arc opening facing upwards. The lower half of the cable outlet 322 extends rearward from the rear side wall of the second main body 321, and the interior of the lower half of the cable outlet 322 is connected to the opening 3211 inside the second main body 321.

[0049] Preferably, the inner wall of the lower half of the cable outlet 322 is further provided with a second sealing member 36. The second sealing member 36 is disposed near the rear end of the lower half of the cable outlet 322 (in this preferred embodiment, at the rear end). The second sealing member 36 extends circumferentially along the inner wall of the lower half of the cable outlet 322 and is in the shape of a vertically placed semi-circular arc. The second sealing member 36 is preferably symmetrically arranged with the first sealing member 35. The second sealing member 36 can also be made of liquid silicone and formed on the lower half of the cable outlet 322 of the lower housing 32 by liquid silicone injection molding process.

[0050] In this preferred embodiment, the upper surface of the second body 321 and the upper surface of the lower half of the cable outlet tube 322 form a second mating surface 320 surrounding the opening 3211 therein, and the rear end has a second opening 3202, and the second sealing member 36 is disposed along the second opening 3202.

[0051] based on Figures 5 to 8 The structure shown, combined with Figure 4 When the upper housing 31 and the lower housing 32 are joined together, the screws 33 pass through the second screw hole 3213 of the lower housing 32 and are locked to the first screw hole 3114 of the upper housing 31, thus locking the lower housing 32 and the upper housing 31 together.

[0052] At this time, the first body 311 of the upper housing 31 and the second body 321 of the lower housing 32 are spliced ​​together. The receiving cavity 3111 of the first body 311 communicates with the opening 3211 of the second body 321 to jointly accommodate the terminal module 1. The mating portion 121 of the conductive terminal 12 of the terminal module 1 is exposed to the outside through the opening 3211 for connection with the mating connector 200. The mating direction of the mating portion 121 is along the vertical direction.

[0053] The upper half of the cable outlet tube 312 of the upper housing 31 and the lower half of the cable outlet tube 322 of the lower housing 32 are joined together, forming an outlet 302 through which the cable 2 passes. The outlet 302 extends in the front-to-back direction and is set at a 90-degree angle to the docking direction of the docking part 121. The outer surface of the combined structure of the upper half of the cable outlet tube 312 and the lower half of the cable outlet tube 322 is also provided with an external thread 306 for engaging with the cap 6.

[0054] The first mating surface 310 of the upper housing 31 faces the second mating surface 320 of the lower housing 32. Through the tightening action of three screws 33, the sealing ring 34 is pressed between the first mating surface 310 and the second mating surface 320 to form a seal. Since the sealing ring 34 extends continuously around the receiving cavity 3111 and is only open near the outlet 302, it effectively prevents external water droplets from entering the receiving cavity 3111 and the opening 3211 through the mating surface between the upper housing 31 and the lower housing 32, thus achieving a waterproof seal.

[0055] The first seal 35 inside the upper housing 31 and the second seal 36 inside the lower housing 32 can be correspondingly fitted together to tightly seal the outlet 302 of the cable 2, forming a waterproof seal on the outer periphery of the cable 2 and preventing external water droplets from entering the interior of the housing 3 through the outlet 302. Since the first seal 35 and the sealing ring 34 form a closed structure, a circumferentially closed waterproof structure is formed between the upper housing 31 and the lower housing 32, resulting in a better waterproof sealing effect. It is worth mentioning that in some embodiments not shown, the sealing ring 34 can also be formed on the second mating surface 320 and connected to the second seal 36; while the first seal 35 is a separate entity.

[0056] When the upper housing 31 and the lower housing 32 are joined together, the plurality of positioning pins 3113 of the upper housing 31 extend into the positioning holes 3212 of the lower housing 32, providing a positioning function during the joining of the upper housing 31 and the lower housing 32, which helps to reduce the misalignment of the sealing ring 34 and improve the reliability of the seal. In other embodiments not shown, positioning holes may be provided on the upper housing 31, and matching positioning pins may be provided on the lower housing 32; alternatively, positioning holes and positioning pins may be provided on both the upper housing 31 and the lower housing 32, with the positioning holes and positioning pins correspondingly matched.

[0057] In some embodiments not shown, the upper housing 31 and the lower housing 32 are not limited to being fastened by screws 33, but can also be spliced ​​together by other structural cooperation methods, such as snap-fit ​​structure cooperation.

[0058] Based on the above structural description, the assembly process of the electrical connector 100 is roughly as follows: Each wire 21 of the cable 2, which is fitted with the locking member 5 and the cap 6, is connected to the tail 122 of each conductive terminal 12 of the terminal module 1; then, the cable 2 is aligned with the upper half of the cable outlet tube 312 of the upper housing 31, and the terminal module 1 is installed and fixed in the receiving cavity 3111 of the upper housing 31. In this preferred embodiment, the latching arm 3112 within the receiving cavity 3111 can be used to secure the insulating base 11 of the terminal module 1. At this time, the cable 2 and the terminal module 1 are integrally installed into the upper housing 31, and the limiting ring 23 of the cable 2 can be limited to the rear of the upper half of the cable outlet tube 312. The lower housing 32 is then attached to the lower part of the upper housing 31 and secured to the upper housing 31 with three screws 33. At this time, the sealing ring 34 is squeezed between the upper housing 31 and the lower housing 32 to provide a waterproof seal. Next, the cap 6 is fitted onto the cable outlet 302 of the outer housing 3. The cap 6 is locked in place with the external thread 306 and the locking member 5 located inside is squeezed to fix the cable 2. At this time, the first sealing member 35 and the second sealing member 36 surround the outer periphery of the cable 2 and are squeezed to prevent water droplets from seeping in from the cable outlet 302. Finally, the locking structure 4 is installed onto the first body 311 of the upper housing 31.

[0059] In this embodiment, the electrical connector 100, where the mating direction of the mating part 121 is set at a 90-degree angle to the outgoing direction of the cable 2, adopts a structure in which the outer shell 3 is composed of an upper shell 31 and a lower shell 32 joined together. This eliminates the need to pull the cable 2 during the assembly process of the electrical connector 100, thus eliminating the pulling and threading process required in traditional electrical connector assembly and fundamentally improving assembly efficiency. Furthermore, compared to traditional designs, this embodiment allows for the connection of each wire 21 to the conductive terminal 12 of the terminal module 1 before the entire assembly is inserted into the upper shell 31. This makes operation less constrained by space limitations and extremely convenient.

[0060] Combination Figure 1 , Figure 3 , Figures 5 to 7 The electrical connector 100 can be locked to the mating connector 200 by means of the locking structure 4 which is pivotally connected to both sides of the upper housing 31.

[0061] Specifically, such as Figure 5 and Figure 6 As shown, the locking structure 4 mainly includes a body 41, two locking arms 42 extending from both sides of the body 41, and two locking spring pieces 43 protruding inward from the middle of the body 41. The upper part of each locking arm 42 has a pivot portion 421 protruding towards the other locking arm 42. The lower part of each locking arm 42 has a locking notch 422 on the end side away from the body 41. At the end of the locking notch 422, a reinforcing connecting piece 423 bends outward from the plane of the locking arm 42. The reinforcing connecting piece 423 bridges both sides of the locking notch 422 to strengthen its strength and prevent it from opening under force during locking, thus causing locking failure.

[0062] The pivot portion 421 of the locking structure 4 can be inserted into the corresponding pivot portion 3115 on the first body 311, so that the locking structure 4 is pivotally connected to the upper housing 31. The locking spring piece 43 can be correspondingly engaged with the locking protrusion 3116 of the first body 311 to lock the locking structure 4 and prevent it from rotating improperly relative to the first body 311 in the locked state.

[0063] When the electrical connector 100 mates with the mating connector 200, the locking piece 201 of the mating connector 200 can extend into the locking groove 3214 of the lower housing 32, and the locking structure 4 can rotate downward so that the lower end of its locking arm 42 extends into the locking groove 3214, so that the locking notch 422 of the locking arm 42 corresponds to the locking protrusion 2011 of the locking piece 201 and locks it, thereby locking the electrical connector 100 and the mating connector 200.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the implementation of the present invention. Those skilled in the art can easily make corresponding modifications or alterations based on the main concept and spirit of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of protection claimed in the claims.
