It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0053] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0055] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0056] like Figure 1 to Figure 2 As shown, the X direction shown in the figure refers to the first direction. This embodiment provides a connector, which includes a connection shell 1, a terminal 10, a needle seat 2, a first seal 3 and a locking member 4. The connection shell 1 is provided with a through hole 11, and the terminal 10 is arranged in the through hole 11. The terminal 10 is used for connection with the connection member to be connected. The needle seat 2 is provided with a groove 21 and a connecting needle 22, and the connecting needle 22 is at least partially arranged in the groove 21. When the connection shell 1 is connected to the needle seat 2, the connection shell 1 is at least partially inserted into the groove 21, and the terminal 10 is electrically connected to the connecting needle 22. The first seal 3 is sealed and connected between the outer wall of the connection shell 1 and the inner wall of the groove 21, that is, the thickness of the first seal 3 is greater than the distance between the outer wall of the connection shell 1 and the inner wall of the groove 21. The locking member 4 is detachably connected to the connection shell 1, and the first seal 3 is sandwiched between the connection shell 1 and the locking member 4. When the connection shell 1 is connected to the needle seat 2, the first seal 3 and the locking member 4 are located in the groove 21. The locking member 4 and the connecting shell 1 can clamp the first sealing member 3 in the first direction, thereby reducing the movement of the first sealing member 3 in the first direction and maintaining the sealing performance of the first sealing member 3. The first sealing member 3 and the locking member 4 can also provide support for the connecting shell 1 and reduce the vibration of the connecting shell 1.

[0057] The first seal 3 has a certain height. The first seal 3 is sandwiched between the outer wall of the connecting shell 1 and the inner wall of the groove 21 and between the connecting shell 1 and the locking piece 4, which can stabilize the position of the connecting shell and the needle seat and make the connecting shell 1 and the groove 21 fit tightly. The surface of the first seal 3 forms a large-scale surface seal with the outer wall of the connecting shell 1 or the inner wall of the groove 21, forming good air tightness, effectively preventing impurities such as rainwater or dust from entering the interior of the connecting shell 1 and the needle seat 2, reducing the damage of impurities such as rainwater or dust to the electrical connection state of the terminal 10 and the connecting needle 22, reducing the occurrence of circuit short circuits, improving the waterproof effect, and solving the problem of easy water ingress in the connector in the related art.

[0058] In this embodiment, Figure 1-2 The X direction shown in the figure refers to the first direction, and the connecting shell 1 can be installed in the groove 21 of the needle seat 2 along the first direction. The first sealing member 3 can be made of elastic material or non-elastic material. Optionally, the first sealing member 3 can be made of elastic material so that the first sealing member 3 can elastically abut between the outer wall of the connecting shell 1 and the inner wall of the groove 21, thereby improving the sealing and shock resistance between the connecting shell 1 and the needle seat 2. The height of the first sealing member 3 can be equal to or greater than one quarter of the depth of the groove 21.

[0059] The through holes 11, the terminals 10 and the connecting pins 22 may be arranged in groups corresponding to each other, and multiple groups of through holes 11, terminals 10 and connecting pins 22 may be arranged in a matrix, so that multiple groups of electronic components can be electrically connected respectively.

[0060] like Figure 2 As shown, in some embodiments, the connector also includes a second seal 8, which is sealed and connected in the through hole 11, and the second seal 8 is arranged at the end of the terminal 10 connected to the part to be connected, that is, the second seal 8 can seal the through hole 11 to form good air tightness, improve the waterproof effect of the end position of the terminal 10, reduce the contact between water in the external environment and the connection point between the terminal 10 and the part to be connected, and reduce the circuit short circuit.

[0061] In this embodiment, the terminal 10 and the connection shell 1 are detachably connected, and the connection method may be, but is not limited to, snap connection, bonding, magnetic connection or threaded connection.

[0062] like Figures 2 to 3 As shown, in some embodiments, the first seal 3 and the second seal 8 may include an elastic tube and a plurality of protrusions, each protrusion is arranged along the circumference of the elastic tube, and the plurality of protrusions are arranged in sequence along the axial direction of the elastic tube.

[0063] Specifically, the first sealing member 3 includes a first elastic tube 31 and a plurality of first protrusions 32. The first elastic tube 31 is sleeved on the outer wall of the connecting shell 1. The first protrusions 32 are arranged on the outer wall and / or inner wall of the first elastic tube 31, that is, the first protrusions 32 can be arranged only on the outer wall or inner wall of the first elastic tube 31, or can be arranged on both the inner and outer walls of the first elastic tube 31. The top of the first protrusion 32 is used to abut against the inner wall of the groove 21 or the outer wall of the connecting shell 1. Each first protrusion 32 is arranged along the circumference of the first elastic tube 31 so that the first protrusion 32 forms an annular protrusion, and the first protrusion 32 seals the circumference of the first elastic tube 31. The plurality of first protrusions 32 are arranged in sequence along the axial direction of the first elastic tube 31, and can form a multi-layer seal from the opening of the groove 21 to the bottom of the groove 21, and form a plurality of reinforced sealing positions within the sealing range, further improving the waterproof effect.

[0064] Moreover, the first elastic tube 31 and the first protrusion 32 can both be made of elastic material and can be integrally formed. The first elastic tube 31 can undergo elastic deformation to a certain extent and can perform buffering and vibration reduction between the outer wall of the connecting shell 1 and the inner wall of the groove 21, thereby improving the damping and anti-vibration effects between the connecting shell 1 and the needle seat 2, reducing the influence of bumpy road conditions on the connection state between the connecting shell 1 and the needle seat 2, and improving the connection performance between the connecting shell 1 and the needle seat 2.

[0065] like Figure 2 and Fig.11 As shown, in some embodiments, the second sealing member 8 includes a second elastic tube 81 and a plurality of second protrusions 82, the second elastic tube 81 is arranged in the through hole 11, the part to be connected can be passed through the second elastic tube 81 and connected to the terminal 10, and the second elastic tube 81 can be sealed and connected between the outer wall of the part to be connected and the inner wall of the through hole 11.

[0066] The second protrusion 82 is arranged on the outer wall and / or inner wall of the second elastic tube 81, that is, the second protrusion 82 can be only arranged on the outer wall of the second elastic tube 81 or only arranged on the inner wall of the second elastic tube 81, or can be simultaneously arranged on the outer wall or the inner wall of the second elastic tube 81, and the top of the second protrusion 82 is used to abut against the inner wall of the through hole 11 or the outer wall of the part to be connected, and each second protrusion 82 is arranged along the circumference of the second elastic tube 81 to form a seal on the circumference of the second elastic tube 81. Multiple second protrusions 82 are arranged in sequence along the axial direction of the second elastic tube 81, and can form a multi-layer seal from the opening position of the through hole 11 to the position of the terminal 10, forming multiple reinforced sealing positions, and further improving the waterproof effect.

[0067] Moreover, the second elastic tube 81 and the second protrusion 82 can both be made of elastic material and can be integrally formed. The second elastic tube 81 can undergo elastic deformation to a certain extent, and can form a buffer and vibration reduction between the part to be connected and the inner wall of the through hole 11 of the connecting shell 1, thereby improving the damping and anti-vibration effects between the part to be connected and the connecting shell 1, reducing the influence of bumpy road conditions on the connection state between the part to be connected and the connecting shell 1, and improving the connection performance between the part to be connected and the connecting shell 1.

[0068] like Figure 1 to Figure 2 As shown, in some embodiments, a detachable connection mechanism is provided between the connection shell 1 and the needle seat 2, and the connection method of the detachable connection mechanism can be, but is not limited to, snap connection, magnetic connection, bonding or bolt connection. Optionally, the detachable connection mechanism includes a hook 13 and a clamp 23, one of which is provided on the side of the connection shell 1, and the other is provided on the side of the needle seat 2. When the connection shell 1 is connected to the needle seat 2, the hook 13 is connected to the clamp 23, so that the connection shell 1 and the needle seat 2 can be firmly snapped and fixed, and the connection shell 1 and the needle seat 2 are prevented from being separated. For example, the hook 13 can be provided on the side of the connection shell 1, and the clamp 23 can be provided on the side of the needle seat 2. The thickness of the hook 13 can be greater than the thickness of the connection shell 1, and the width of the hook 13 can be equal to or greater than one quarter of the length of the connection shell 1, so as to improve the stability of the connection between the connection shell 1 and the needle seat 2.

[0069] like Figures 4 to 5 As shown, in some embodiments, a limiting portion 12 is provided on the outer wall of the connection shell 1. The limiting portion 12 may be, but is not limited to, an annular groove or an annular protrusion, and is used to abut and limit the end of the first sealing member 3. When the locking member 4 is connected to the connection shell 1, the first sealing member 3 is clamped between the limiting portion 12 and the end of the locking member 4. The limiting portion 12 and the locking member 4 can clamp the first sealing member 3 in the first direction, which can not only reduce the movement of the first sealing member 3 in the first direction and maintain the sealing performance of the first sealing member 3, but also enable the first sealing member 3 to provide support for the connection shell 1 and reduce the vibration of the connection shell 1.

[0070] In this embodiment, the locking member 4 is detachably connected to the outer wall of the connecting shell 1, and the locking member 4 can directly abut and limit the first sealing member 3 through its own end, or the end or side of the locking member 4 can also be provided with an annular groove or an annular protrusion to limit the end of the first sealing member 3.

[0071] like Figures 6 to 8 As shown, in some embodiments, the connector further includes a plurality of first foolproofing mechanisms 5, and the first foolproofing mechanisms 5 are clamped between the locking member 4 and the connection shell 1, that is, the locking member 4 and the connection shell 1 are clamped through the first foolproofing mechanisms 5. The plurality of first foolproofing mechanisms 5 are disposed on both sides of the locking member 4, and the sizes or quantities of the first foolproofing mechanisms 5 on both sides of the locking member 4 are different.

[0072] With such a configuration, the first anti-foolproofing mechanism 5 can clamp and fix the locking piece 4 and the connecting shell 1, and the first anti-foolproofing mechanisms 5 located on both sides of the locking piece 4 can form an anti-foolproofing structure due to different sizes or numbers, so that the locking piece 4 can only be connected and fixed to the connecting shell 1 in one installation method. If the locking piece 4 is misplaced or installed in reverse, the locking piece 4 cannot complete the connection with the connecting shell 1, thereby reducing the situation where the operator installs the piece in reverse or incorrectly during the installation process.

[0073] In this embodiment, the first anti-mistake mechanism 5 includes a connected card slot 51 and a card block 52, one of the card slot 51 and the card block 52 is set on the locking member 4, and the other is set on the connecting shell 1. When the locking member 4 is connected to the connecting shell 1, the card block 52 is clamped in the card slot 51 for locking and fixing.

[0074] The different sizes of the first foolproof mechanism 5 on both sides of the locking member 4 means that the card slots 51 on both sides of the locking member 4 can be set to different shapes or different widths or depths, and the card block 52 has the same cross-sectional profile size as the card slot 51, and the card slot 51 can only be connected with the card block 52 of the same size, such as Figures 6 to 8 The first foolproofing mechanism 5a and the first foolproofing mechanism 5b are shown. The different numbers of the first foolproofing mechanisms 5 on both sides of the locking member 4 means that the card slots 51 on both sides of the locking member 4 can be set to different numbers, and the card blocks 52 are the same in number and position as the card slots 51. In this case, the sizes of the card slots 51 on both sides of the locking member 4 can be the same or different. For example, one card slot 51 can be set on one side of the locking member 4, and two card slots 51 can be set on the other side. The two card slots 51 can only be connected with two card blocks 52 of the same number.

[0075] like Figures 9 and 10 As shown, in some embodiments, the connector further includes a plurality of second foolproofing mechanisms 6, which are connected between the locking member 4 and the needle seat 2, and each second foolproofing mechanism 6 can be arranged along the first direction, and a plurality of second foolproofing mechanisms 6 are arranged on both sides of the locking member 4, and the sizes or numbers of the second foolproofing mechanisms 6 on both sides of the locking member 4 are different, and the foolproofing principle thereof can refer to the first foolproofing mechanism 5 mentioned above, and in this way, after the locking member 4 is connected to the connecting shell 1, the combination of the two can be inserted into the groove 21 of the needle seat 2 through the second foolproofing mechanism 6, and the second foolproofing mechanism 6 can guide the installation of the locking member 4, and the second foolproofing mechanisms 6 on both sides of the locking member 4 can form a foolproofing structure due to the different sizes or numbers, so that the locking member 4 can only be installed in the groove 21 of the needle seat 2 in one installation mode. If the locking member 4 is misplaced or reversely installed, the locking member 4 cannot be connected to the needle seat 2, reducing the situation of reverse installation or misinstallation by the operator during the installation process.

[0076] like Figures 9 and 10As shown, in this embodiment, the second anti-mistake mechanism 6 includes a guide groove 61 and a slider 62 that are connected to each other. One of the guide groove 61 and the slider 62 is arranged on the locking member 4, and the other is arranged on the needle seat 2. When the locking member 4 is connected to the needle seat 2, the slider 62 extends into the guide groove 61 to guide and limit the installation of the locking member 4 and the needle seat 2.

[0077] Among them, when the first foolproofing mechanism 5 and the second foolproofing mechanism 6 are provided together, the first foolproofing mechanism 5 and the second foolproofing mechanism 6 can be provided on different sides of the locking member 4, so that the first foolproofing mechanism 5 and the second foolproofing mechanism 6 can have a larger layout range and reduce position interference. For example, the locking member 4 can be configured as a rectangular shell structure, the cross section of the locking member 4 can be rectangular, the locking member 4 has two pairs of side walls, the first foolproofing mechanism 5 can be provided on a pair of side walls of the locking member 4, and the second foolproofing mechanism 6 can be provided on the other pair of side walls of the locking member 4.

[0078] like Figures 5 to 7 As shown, in some embodiments, the connector also includes a third anti-fool mechanism 9, which is clamped between the terminal 10 and the connecting shell 1. When the terminal 10 and the connecting shell 1 are not connected in place, the size of the connecting shell 1 is larger than the size of the locking piece 4, that is, when the terminal 10 and the connecting shell 1 are not connected in place, the locking piece 4 cannot be assembled with the connecting shell 1. Only when the terminal 10 and the connecting shell 1 are installed in place, the size of the connecting shell 1 can be restored for the locking piece 4 to connect. The third anti-fool mechanism 9 is clamped to lock and fix the terminal 10 and the connecting shell 1, so that the operator can perform self-inspection and reduce the situation where the terminal 10 is installed upside down or not in place.

[0079] like Figures 5 and 6 As shown, in this embodiment, the third foolproof mechanism 9 may include a card plate 91 and a hook 92. The card plate 91 may be arranged on one side of the through hole 11, and the hook 92 may be arranged on the side of the terminal 10. For example, the hook 92 may be arranged on the side of the second end of the terminal 10, and the sum of the sizes of the second end of the terminal 10 and the hook 92 may be slightly larger than the size of the through hole 11 where the card plate 91 is located. When the terminal 10 is not connected to the connection shell 1 in place, that is, when the terminal 10 is inserted into the through hole 11, the hook 92 squeezes the card plate 91, and the card plate 91 will form a certain degree of elastic deformation. When the terminal 10 is connected to the connection shell 1 in place, that is, when the terminal 10 is inserted into the through hole 11 to a preset position, the hook 92 extends out of the position of the card plate 91, the card plate 91 recovers its deformation, and the hook 92 is hooked on the end of the card plate 91, so that the terminal 10 is locked with the connection shell 1.

[0080] When the locking piece 4 is connected to the connecting shell 1, the locking piece 4 is sleeved on the outer wall of the connecting shell 1. Specifically, the locking piece 4 is sleeved on the outer side of the clamping plate 91. If the terminal 10 is reversed or the terminal 10 is not inserted properly into the through hole 11, the clamping plate 91 will remain deformed and tilted, and the locking piece 4 cannot be assembled with the connecting shell 1. Therefore, by setting the third anti-mistake mechanism 9, the installation status of the terminal 10 can be self-checked, which reduces the situation where the terminal 10 is reversed or not installed properly, and avoids the situation where noisy environments such as production workshops or operators are tired of assembling and only judge by the clamping sound of the terminal 10, which is easy to cause installation errors.

[0081] Among them, a sliding groove can be set in the through hole 11, and the sliding groove and the clamping plate 91 are located on the opposite side walls of the through hole 11. The sliding groove is set along the axial direction of the through hole 11, and the side wall of the terminal 10 is slidingly connected to the sliding groove. The terminal 10 can be slidably connected to the through hole 11 along the sliding groove, so that the connection between the two is smoother and the terminal 10 is installed in a straight direction.

[0082] like Figure 2 and Fig.11 As shown, in some embodiments, the terminal 10 has a first end and a second end that are relatively arranged, and the first end of the terminal 10 is used to connect with the part to be connected. Specifically, the first end of the terminal 10 may be provided with at least two connecting holes, and the part to be connected can be connected to one connecting hole of the terminal 10 so that the part to be connected is locked and fixed to the terminal 10, and the second elastic tube 81 can be connected to the other connecting hole of the terminal 10 so that the second sealing member 8 is locked and fixed to the terminal 10.

[0083] A slot 101 is provided at the second end of the terminal 10, and a connecting pin 22 is provided on the needle seat 2. The connecting pin 22 is at least partially provided in the groove 21, and the connecting pin 22 is plugged into the slot 101. When the combination of the connecting shell 1, the terminal 10 and the locking piece 4 is connected to the groove 21, the connecting shell 1 and the needle seat 2 are firmly connected, and the terminal 10 and the connecting pin 22 are electrically connected and firmly connected, so that the connector can be used for electrical connection between two parts to be connected.

[0084] In this embodiment, when the locking member 4 is connected to the connection shell 1, the terminal 10 can be located in the inner cavity of the locking member 4, and the locking member 4 can limit the second end of the terminal 10, thereby reducing the separation of the terminal 10 from the connection shell 1. The bottom of the locking member 4 or the bottom of the connection shell 1 can be provided with a boss 41 arranged along the radial direction of the through hole 11 and facing the inner cavity of the through hole 11. The boss 41 can be a block-shaped protrusion or an annular flange, which can not only limit the second end of the terminal 10, but also guide and limit the connection needle 22 when it is inserted into the slot 101, so that the combination of the locking member 4, the terminal 10 and the connection shell 1 is easier to connect with the needle seat 2, thereby reducing the displacement of the needle seat 2 or the locking member 4.

[0085] like Figure 5 and Fig.11 As shown, in some embodiments, an elastic sheet 102 is provided on the inner wall of the slot 101, one end of the elastic sheet 102 is connected to the inner wall of the slot 101, and the other end is used to abut against the connecting pin 22, so that an elastic connection is formed between the connecting pin 22 and the slot 101, and the contact electrical connection is formed. The elastic sheet 102 can be made of metal or non-metal material, and the elastic sheet 102 can be a thin sheet structure, which can be elastically deformed after being compressed, and the elastic sheet 102 can be a flat plate or a curved plate.

[0086] like Figure 1 to Figure 2 As shown, the connector of the utility model can be applied to a connection assembly, which includes a first part to be connected, a second part to be connected and the above-mentioned connector. One of the first part to be connected and the second part to be connected is electrically connected to the terminal 10, and the other is electrically connected to the connection needle 22. When the connection shell 1 is connected to the needle seat 2, the terminal 10 is electrically connected to the connection needle 22 to achieve electrical connection between the first part to be connected and the second part to be connected. In addition, by providing a first sealing member 3 between the connection shell 1 and the needle seat 2, the connector can make the connection shell 1 and the groove 21 of the needle seat 2 fit tightly to perform a wide range of surface sealing, thereby improving the waterproof effect.

[0087] Specifically, the first part to be connected can be connected to the needle seat 2, so that the first part to be connected is electrically connected to the connecting needle 22 on the needle seat 2, and the second part to be connected can be connected to the through hole 11 of the connection shell 1, so that the second part to be connected is electrically connected to the terminal 10. The first part to be connected can be configured as a wiring harness, and the second part to be connected can be configured as a controller. The controller and the wiring harness can be connected through a connector, which improves the waterproof effect of the connection position between the controller and the wiring harness.

[0088] like Fig.12 As shown, in some embodiments, a fourth fool-proofing mechanism 7 may be provided at the bottom of the needle seat 2. The fourth fool-proofing mechanism 7 may include a plurality of connecting columns 71 of different sizes, for example, Fig.12 The two connecting columns 71a and 71b of different sizes are shown in the figure. When the needle seat 2 is connected to the first part to be connected, the fourth anti-mistake mechanism 7 is connected between the needle seat 2 and the first part to be connected, which can avoid the situation where the needle seat 2 and the first part to be connected are reversed or misinstalled.

[0089] See also Figure 1-11 , taking the connection between the connector and the wiring harness and the controller as an example, the installation steps of the connection assembly are explained:

[0090] First, the wiring harness can be fixedly connected to the first end of the terminal 10 and then inserted into the through hole 11 of the connecting shell 1 along the first direction. The terminal 10 and the connecting shell 1 are locked by the third anti-foolproofing mechanism 9, and the third anti-foolproofing mechanism 9 can reduce the misassembly of the terminal 10 and the connecting shell 1. The second sealing ring is sealed and connected between the wiring harness and the inner wall of the through hole 11, and the needle seat 2 is connected to the controller.

[0091] Then the first sealing member 3 is sleeved on the outer wall of the connecting shell 1, and the locking member 4 and the connecting shell 1 are locked by snap-fitting through the first anti-foolproofing mechanism 5. The first sealing member 3 is clamped between the end of the locking member 4 and the limiting portion 12. The first anti-foolproofing mechanism 5 can reduce the misassembly of the locking member 4 and the connecting shell 1.

[0092] Finally, the combination of the connection shell 1 and the locking member 4 can be installed into the groove 21 of the needle seat 2, so that the connection needle 22 is plugged into the slot 101, so that the controller is electrically connected to the wiring harness. The elastic sheet 102 in the slot 101 can keep the force value of multiple plugging and unplugging within the elastic force range, thereby improving the connection reliability. The side of the connection shell 1 and the needle seat 2 can be clamped and fixed by the hook 13 and the clamp head 23. The first sealing member 3 is sealed and connected between the connection shell 1 and the inner wall of the groove 21, thereby improving the waterproof effect between the connection shell 1 and the needle seat 2, and the first sealing member 3 can be made of elastic material to improve the shock resistance between the connection shell 1 and the needle seat 2.

[0093] The connector of the utility model can be applied to vehicles, and the vehicle may include the above-mentioned connection assembly, which can be used to connect the vehicle's controller and wiring harness, instrument panel and wiring harness, lamp and wiring harness, or anti-theft device and wiring harness, etc., to effectively prevent impurities such as rainwater or dust from entering the connection position, and improve the waterproof level of the connection position of the vehicle's electrical components. In a high humidity environment or a dusty environment, the connection assembly can reduce the impact of rainwater or dust on electronic components such as controllers and instruments, and reduce soaking and splashing on flooded roads. When the vehicle is transported in coastal areas or at sea, the connection assembly can protect the electronic components on the vehicle from the corrosion of moisture and coastal alkaline salt environments, and improve the reliability and durability of the electronic components. Under harsh environmental conditions, the connection assembly can protect the vehicle from stable operation. Facing bumpy roads, the first seal 3 has the function of adsorption and shock absorption, and improves the damping and anti-seismic effects between the connection shell 1 and the needle seat 2.

[0094] Among them, the vehicle can be configured as an electric two-wheeled vehicle.
