They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0039] Please refer to the following: Figures 1 to 26 The switch provided by the present invention will now be described. The switch includes a lower housing 2 having a receiving cavity 21, an upper housing 11 detachably covering the lower housing 2 and having a receiving cavity 111, a plug 12 disposed in the receiving cavity 111, and a female terminal 3 disposed in the receiving cavity 21 and engaging with the plug 12; when the upper housing 11 covers the lower housing 2, the plug 12 is connected to the female terminal 3, and the upper housing 11 and the lower housing 2 enclose a sealed space; a tensioning system for tightening the upper housing 11 and the lower housing 2 is provided between the upper housing 11 and the lower housing 2.

[0040] Thus, when the upper housing 11 is closed onto the lower housing 2, the plug 12 and the female terminal 3 are connected, and current can flow through the plug 12 and the female terminal 3; when the upper housing 11 is separated from the lower housing 2, the plug 12 and the female terminal 3 are disconnected, breaking the circuit; the plug 12 is located in the receiving cavity 111 of the upper housing 11, and the female terminal 3 is located in the receiving cavity 21 of the lower housing 2, reducing the impact of external dust / moisture on the plug 12 and the female terminal 3; the upper housing 11 covers the lower housing 2 to form a sealed space (optionally, the sealed space is a sealed space), and the plug 12 and the female terminal 3 are both located in the sealed space, reducing the impact of dust / moisture on the plug 12 and the female terminal 3; the housings 2 are tightened by a tensioning system, ensuring the firmness between the upper housing 11 and the lower housing 2 and preventing loosening, that is, reducing the entry of external dust / moisture into the sealed space enclosed by the upper housing 11 and the lower housing 2.

[0041] Further, please refer to Figures 1 to 26As a specific embodiment of the switch provided by the present invention, the tensioning system includes a handle 51 pivotally connected to the upper housing 11 via a pivot 7, a first fastening component disposed between the upper housing 11 and the lower housing 2 for tensioning the upper housing 11 onto the lower housing 2, and a second fastening component disposed between the handle 51 and the lower housing 2 for fixing the handle 51 onto the lower housing 2. Thus, the user can easily open the upper housing 11 by gripping the handle 51; after closing the upper housing 11 and the lower housing 2, the upper housing 11 is fixed to the lower housing 2 by the first fastening component, ensuring the stability between the upper housing 11 and the lower housing 2; then, the handle 51 is fixed to the lower housing 2 by the second fastening component, ensuring the stability of the handle 51; and the upper housing 11 is fixed to the lower housing 2 by the handle 51, further enhancing the stability of the connection between the upper housing 11 and the lower housing 2.

[0042] Further, please refer to Figures 1 to 26 As a specific embodiment of the switch provided by the present invention, the first fastening assembly includes a first slide groove 511 formed on the handle 51 and a rod 8 disposed on the lower housing 2 for sliding into the first slide groove 511 and sliding along the first slide groove 511; one end of the first slide groove 511 is an inlet 5111, and on the sliding path of the rod 8 entering from the inlet 5111 of the first slide groove 511 and sliding along the first slide groove 511, the distance of the sliding path from the pivot 7 gradually decreases. Thus, after the upper housing 11 is placed on the lower housing 2, the rod 8 first engages with the inlet 5111 of the first sliding groove 511, and then rotates the handle 51 around the pivot 7, allowing the rod 8 to move along the first sliding groove 511. Since the distance between the sliding path and the pivot 7 is reduced along the sliding path of the rod 8 along the first sliding groove 511, the distance between the pivot 7 and the rod 8 is shortened, so that when the rod 8 slides along the first sliding groove 511, it can press the upper housing 11 tightly onto the lower housing 2, ensuring the firmness between the lower housing 2 and the upper housing 11.

[0043] Furthermore, in one embodiment, the first groove 511 is a slotted hole formed on the handle 51. This makes the slotted hole easy to manufacture, and the rod 8 easy to slide along the slotted hole.

[0044] Furthermore, in one embodiment, the rod 8 passes through the slotted hole. This prevents the rod 8 from easily coming out.

[0045] Furthermore, in one embodiment, the diameter of the rod 8 is the same as the width of the slot. This prevents the rod 8 from easily wobbling when sliding along the slot.

[0046] Further, please refer to Figures 1 to 26As a specific embodiment of the switch provided by the present invention, the inner wall of the first slide groove 511 has a recessed locking position protruding towards the pivot 7 and for the rod 8 to be engaged. In this way, when the rod 8 is engaged in the recessed locking position, the rod 8 can be positioned in the recessed locking position, preventing the rod 8 from sliding backward along the first slide groove 511; in addition, when the rod 8 is engaged in the recessed locking position, the rod 8 hits the recessed locking position and produces a sound, which the user can use to determine whether the rod 8 has been engaged.

[0047] Furthermore, in one embodiment, a reinforcing member 5112 is provided on the handle 51 on the outer side of the inlet 5111, and the two ends of the reinforcing member 5112 are respectively connected to the handles 51 on both sides of the first slide groove 511. In this way, the reinforcing member 5112 can reduce the deformation at the inlet 5111 of the first slide groove 511.

[0048] Furthermore, in one embodiment, a third reinforcing rib 5113 is provided at the edge of the first groove 511. In this way, the third reinforcing rib 5113 can reduce the deformation of the first groove 511 itself.

[0049] Further, please refer to Figures 1 to 26 As a specific embodiment of the switch provided by the present invention, the second fastening assembly includes a locking position 64 disposed on the lower housing 2 and an elastic plate 52 disposed on the handle 51; the elastic plate 52 is provided with a hook 521 for engaging with the locking position 64, and the handle 51 is provided with a pressing mechanism 6 for pressing the hook 521 hooked on the locking position 64 against the locking position 64. Thus, the lower housing 2 is provided with the locking position 64, and the upper housing 11 is provided with the handle 51, which can rotate around the pivot 7; the handle 51 is provided with the elastic plate 52, and the elastic plate 52 has a hook 521. When the hook 521 is engaged with the locking position 64, the handle 51 is fixed; the pressing mechanism 6 then presses the hook 521 against the locking position 64, greatly enhancing the firmness between the hook 521 and the locking position 64 and preventing the handle 51 from loosening.

[0050] Alternatively, in one embodiment, the elastic plate 52 is a plastic plate.

[0051] Optionally, in one embodiment, the locking position 64 is a protrusion for the locking hook 521 to engage. In another embodiment, the locking position 64 is a first recessed space for the locking hook 521 to engage.

[0052] Further, please refer to Figures 1 to 26As a specific embodiment of the switch provided by the present invention, the pressing mechanism 6 includes a second slide groove 61, a sliding plate 62, and an elastic plate 52 formed on the handle 51. The elastic plate 52 is disposed on the side wall of the second slide groove 61, and the elastic plate 52 is spaced apart from the bottom wall of the second slide groove 61, and a slide track for the sliding plate 62 to slide is formed between the elastic plate 52 and the bottom wall of the second slide groove 61. A first protrusion 522 extending into the slide track is provided on the elastic plate 52, and the hook 521 and the sliding plate 62 are respectively located on opposite sides of the elastic plate 52. Thus, a slide track is formed between the elastic plate 52 and the bottom wall of the second slide groove 61, and the sliding plate 62 slides in the slide track. Since the first protrusion 522 extends into the slide track, when the sliding plate 62 touches the first protrusion 522, the sliding plate 62 bends the elastic plate 52 toward the side where the hook 521 is located through the first protrusion 522, and the bent elastic plate 52 presses the hook 521 onto the locking position 64.

[0053] Furthermore, in one embodiment, the sliding plate 62 is provided with a second protrusion 621 protruding towards the elastic plate 52. In this way, the second protrusion 621 can more easily contact the first protrusion 522 and push the elastic plate 52 to bend.

[0054] Furthermore, in one embodiment, a strip groove 611 is provided on the bottom wall of the second slide groove 61, and a hook 622 for engaging with the strip groove 611 is provided on the sliding plate 62. In this way, the hook 622, constrained by the strip groove 611, prevents the sliding plate 62 from detaching from the slide.

[0055] Furthermore, in one embodiment, the hook 622 has a second guide surface for guiding the hook 622 to slide along the bottom wall of the strip groove 611. Thus, when the sliding plate 62 moves the hook 622 along the strip groove 611, the second guide surface can guide the hook 622 to slide.

[0056] Furthermore, in one embodiment, a boss 6111 is provided in the strip groove 611. In this way, when the hook 622 encounters the boss 6111, it can limit the hook 622; when the sliding plate 62 is disassembled, the hook 622 can slide out of the strip groove 611 through the boss 6111.

[0057] Furthermore, in one embodiment, the sliding plate 62 is provided with a push plate 63 for the user to push. In this way, the user can easily push the sliding plate 62 to slide using the push plate 63.

[0058] Furthermore, in one embodiment, the sliding direction of the push plate 63 is perpendicular to that of the sliding plate 62. This allows the user to easily move the push plate 63 when pushing the sliding plate 62.

[0059] Furthermore, in one embodiment, the upper housing 11 is provided with a positioning groove, and the handle 51 is provided with a protrusion; when the handle 51 is rotated to a predetermined angle, the protrusion is engaged in the positioning groove and abuts against the inner wall of the positioning groove. In this way, the handle 51 rotates via the pivot 7, and when the handle 51 is rotated to the predetermined angle, the protrusion is engaged in the positioning groove, and the positioning groove can provide a good limiting effect for the protrusion, making it less prone to damage; the protrusion is relatively firm after abutting against the inner wall of the positioning groove.

[0060] Furthermore, in one embodiment, the upper housing 11 is provided with a first rib and a second rib spaced apart, and a positioning groove is formed between the first rib and the second rib. In this way, using ribs to form the positioning groove saves material and reduces weight.

[0061] Furthermore, in one embodiment, the positioning groove is located on the top wall of the upper housing 11, and the pivot 7 is located on the side wall of the upper housing 11. In this way, the positioning groove is formed on the top wall, which makes production easier, and when the positioning groove is subjected to pressure, the pressure is distributed to the upper housing 11, making it less likely to be damaged; the pivot 7 is located on the side wall, which reduces the space occupied.

[0062] Furthermore, in one embodiment, a first reinforcing rib disposed on the upper housing 11 is connected to the second rib. In this way, the first reinforcing rib can increase the strength of the second rib.

[0063] Furthermore, in one embodiment, a second reinforcing rib is connected to the protrusion and disposed on the handle 51. In this way, the second reinforcing rib can increase the strength of the protrusion.

[0064] Furthermore, in one embodiment, the pivot 7 includes two coaxially arranged shafts; the two shafts are located at opposite ends of the upper housing 11, one end of the handle 51 is hinged to one shaft, and the other end of the handle 51 is pivotally connected to the other shaft. In this way, the external force of the handle 51's rotation is distributed between the two shafts, which helps to maintain the stability of the handle 51's rotation.

[0065] Further, please refer to Figures 1 to 26As a specific embodiment of the switch provided by the present invention, it also includes a dust cover 4; a guide mechanism for guiding the dust cover 4 to slide in a predetermined direction to cover the lower housing 2 is provided between the lower housing 2 and the dust cover 4; a snap-fit ​​mechanism is provided between the lower housing 2 and the dust cover 4; when the dust cover 4 is covered on the lower housing 2, the dust cover 4 is detachably snapped onto the lower housing 2 by the snap-fit ​​mechanism. Thus, when an output cable passes through / throughs the lower housing 2 and makes a conductive connection with the female terminal 3, the dust cover 4 can effectively reduce the impact of dust / moisture on the connection. During the process of placing the dust cover 4 on the lower housing 2, the dust cover 4 slides in a predetermined direction under the guidance of the guide mechanism and covers the lower housing 2, reducing the difficulty of placing the dust cover 4. Under the guidance of the guide mechanism, the dust cover 4 maintains a stable covering direction in the predetermined direction, avoiding the difficulty of covering due to directional disorder during the covering process. At the same time, the guide mechanism also prevents the dust cover 4 from being placed incorrectly. After the dust cover 4 is placed on the lower housing 2, the snap-fit ​​mechanism can prevent the dust cover 4 from becoming loose and also facilitates disassembly.

[0066] Further, please refer to Figures 1 to 26 As a specific embodiment of the switch provided by the present invention, the latching mechanism includes a recess on the outer side wall of the lower housing 2 and a protrusion on the inner side wall of the dust cover 4 for engaging with the recess. The recess has a first flat inner wall, and the protrusion has a flat outer stop wall for abutting against the first inner wall. The first inner wall is located on the movement path of the outer stop wall when the dust cover 4 is removed. Thus, to install the dust cover 4, it is only necessary to place the dust cover 4 on the lower housing 2 and engage the protrusion with the recess. When the protrusion is engaged with the recess, if the dust cover 4 needs to be removed, since the first inner wall on the recess is located on the movement path of the outer stop wall on the protrusion, the flat outer stop wall and the first inner wall can make close contact, and the first inner wall can effectively obstruct the protrusion, thereby improving the firmness of the dust cover 4.

[0067] Optionally, in one embodiment, the guide surface and the outer wall of the stop are connected by an arc-shaped transition surface. Thus, during the process of the guide surface guiding the protrusion into the recess, the arc-shaped transition surface makes it less likely for the protrusion to get stuck.

[0068] Optionally, in one embodiment, the first inner wall and the outer wall of the stop are perpendicular to the disassembly direction of the dust cover 4. Thus, when disassembling the dust cover 4, the outer wall of the stop abuts against the first inner wall, making it less likely for the dust cover 4 to be removed, thereby improving the stability of the dust cover 4.

[0069] Optionally, in one embodiment, the recess further includes a second inner wall, a third inner wall, and a fourth inner wall that are respectively planar; the first inner wall and the second inner wall are arranged parallel to each other; the first inner wall, the second inner wall, the third inner wall, and the fourth inner wall surround to form the recess; the third inner wall and the fourth inner wall form a predetermined angle. Thus, the parallel first inner wall and the second inner wall are easy to process; and the parallel first inner wall and the second inner wall facilitate the confinement of the protrusion between the first inner wall and the second inner wall; the planar first inner wall, the second inner wall, the third inner wall, and the fourth inner wall are easy to process; and the protrusion is less likely to be scratched when in contact with the first inner wall, the second inner wall, the third inner wall, and the fourth inner wall.

[0070] Optionally, in one embodiment, the dust cover 4 has an injection molding hole. This allows the dust cover 4 to be positioned by means of the injection molding hole when the protrusion on the inner side of the dust cover 4 is injection molded.

[0071] Optionally, in one embodiment, the guiding mechanism includes a protrusion and a groove; the outer surface of the lower housing 2 is provided with a protrusion extending in a predetermined direction, and the inner wall of the dust cover 4 is recessed to form a groove that matches the protrusion; a notch 3234 is provided at the edge of the bottom wall of the groove. Thus, when installing the dust cover 4, it is only necessary to place the dust cover 4 on the lower housing 2 in the predetermined direction, the protrusion is inserted into the groove, and the dust cover 4 is pushed in the predetermined direction under the guidance of the protrusion, which is very convenient; since the protrusion and the groove are correspondingly matched, the situation of the dust cover 4 being installed backwards or incorrectly is avoided; the notch 3234 is provided on the bottom wall of the groove, which can release the tension on the groove when the protrusion is inserted into the groove, making the installation of the dust cover 4 more convenient.

[0072] Optionally, in one embodiment, the notch 3234 extends in a predetermined direction. This facilitates the dust cover 4 being placed on the lower housing 2 in the predetermined direction.

[0073] Optionally, in one embodiment, the width of the notch 3234 gradually increases in a predetermined direction. This facilitates the release of stress on the bottom wall of the groove when the notch 3234 is opened under external force.

[0074] Optionally, in one embodiment, the notch 3234 includes a planar left side wall, a planar right side wall, and a curved bottom side wall; the left side wall, right side wall, and bottom side wall enclose and form the notch 3234. In this way, the curved bottom side wall can easily recover from tensile deformation.

[0075] Optionally, in one embodiment, a waterproof gasket is further included. The waterproof gasket includes an elastic waterproof sheet with an assembly hole. The lower housing 2 passes through the assembly hole. The two sides of the waterproof sheet are a first side and a second side, respectively. A plurality of first recesses are formed in the recess of the first side of the waterproof sheet, and a first water-stopping rib is formed between any two adjacent first recesses. A second water-stopping rib is formed around the edge of the first side. Thus, when the user clamps the waterproof sheet of the waterproof gasket between the lower housing 2 and the outer wall of the external equipment, the lower housing 2 can pass through the assembly hole and electrically connect with the external equipment. The cavity space of the first recess can buffer the deformation of the waterproof sheet after being squeezed, which helps the waterproof sheet maintain its elasticity after being squeezed, improves the sealing ability, and reduces water penetration. In addition, when the user clamps the waterproof sheet of the waterproof gasket between the lower housing 2 and the outer wall of the external equipment, the clamping force between the lower housing 2 and the outer wall of the external equipment is borne on the first and second water-stop ribs, which have smaller force-bearing surfaces. This increases the pressure between the first and second water-stop ribs and the lower housing 2 / outer wall of the external equipment, respectively, improving the waterproof sealing performance and reducing water penetration. Furthermore, the second water-stop rib is arranged around the edge of the first side, effectively preventing water from seeping out from the edge of the first side.

[0076] Optionally, in one embodiment, the waterproof gasket has a waterproof rating of IPX to IPX.

[0077] Optionally, in one embodiment, the waterproof sheet has a locking hole, and a fifth water-stop rib is formed around the locking hole on the first side. Thus, screws or other fasteners pass through the locking hole to secure the lower housing 2 and the external equipment. The fifth water-stop rib surrounding the locking hole, in a clamped state, prevents water from seeping from the first side through the fifth water-stop rib to other areas.

[0078] Optionally, in one embodiment, a sixth water-stop rib is formed on the second side surface, which is surrounded by a locking hole. In this way, when the lower housing 2 passes through the locking hole, the sixth water-stop rib surrounding the locking hole can prevent water in the locking hole from seeping from the second side surface through the sixth water-stop rib to other places when clamped.

[0079] Alternatively, in one embodiment, the waterproof sheet is a one-piece molded part made of silicone. In this way, silicone has good waterproof properties.

[0080] Optionally, in one embodiment, the waterproof sheet is an oil-permeable silicone component. Thus, the inclusion of grease in the silicone facilitates a more secure contact between the waterproof sheet and the lower housing 2 or external equipment during installation and clamping.

[0081] Optionally, in one embodiment, a plurality of second recesses, third water-stop ribs, and fourth water-stop ribs are formed on the second side surface; each first recess is symmetrical to each second recess, the first water-stop rib is symmetrical to the third water-stop rib, and the second water-stop rib is symmetrical to the fourth water-stop rib. Thus, when the first and second sides of the waterproof gasket are relatively compressed, the force on the first and second sides is more even.

[0082] Further, please refer to Figures 1 to 26 As a specific embodiment of the switch provided by the present invention, it further includes a male core 13 detachably fixed to the inner wall of the receiving cavity 111, and two female terminals 3; the plug 12 includes a first male terminal 121 for cooperating with one female terminal 3, a second male terminal 122 for cooperating with the other female terminal 3, and a conductive connection portion 123 connecting the first male terminal 121 and the second male terminal 122; the conductive connection portion 123 is confined between the male core 13 and the inner wall of the receiving cavity 111. Thus, when the upper housing 11 and the lower housing 2 are closed, the upper housing 11 can protect the plug 12 located in the receiving cavity 111, and the lower housing 2 can protect the female terminal 3 located in the receiving cavity 21, avoiding loosening caused by external environmental interference with the plug 12 or the female terminal 3, thereby improving safety and reliability; the current sequentially passes through a female terminal 3, a first male terminal 121 (optionally, the first male terminal 121 transmits the current to the second male terminal 122 through the conductive connection part 123), a second male terminal 122, and another female terminal 3 to form a current path. If the above path is to be disconnected, it is only necessary to... The upper housing 11 is removed from the lower housing 2 to separate the male end (male end: first male end 121 and / or second male end 122) from the female end 3; the conductive connection part 123 is confined between the male core 13 and the inner wall of the receiving cavity 111, preventing the conductive connection part 123 from shaking around, thereby reducing the shaking of the first male end 121 / second male end 122 and improving safety and reliability; the first male end 121 is connected to the second male end 122 through the conductive connection part 123, so that the first male end 121 and the second male end 122 can be fixed to each other, reducing loosening and improving safety and reliability.

[0083] Furthermore, in one embodiment, the first male end 121 is inserted into the first mounting hole 131 on the male core 13, reducing the loosening of the first male end 121; the second male end 122 is inserted into another first mounting hole 131 on the male core 13, reducing the loosening of the second male end 122.

[0084] Furthermore, in one embodiment, the male core 13 is secured to the inner wall of the receiving cavity 111 via a snap-fit ​​mechanism. This allows for easy installation and removal of the male core 13.

[0085] Furthermore, in one embodiment, the snap-fit ​​mechanism includes a protrusion on the male core 13 and a recess on the inner wall of the receiving cavity 111; the protrusion is engaged within the recess. Thus, the male core 13 can be easily secured to the outer casing by engaging the protrusion within the recess.

[0086] Furthermore, in one embodiment, the cross-section of the first mounting hole 131 is the same as the cross-section of the first male end 121; and / or the cross-section of the first mounting hole 131 is the same as the cross-section of the second male end 122. Thus, when the first male end 121 is inserted into the first mounting hole 131, it is less prone to wobbling; similarly, when the second male end 122 is inserted into the first mounting hole 131, it is less prone to wobbling.

[0087] Furthermore, in one embodiment, a positioning post is provided on the inner wall of the receiving cavity 111, and a hole is formed on the male rubber core 13 to cooperate with the positioning post; the positioning post is inserted into the hole. In this way, the positioning post passing through the hole can restrict the position of the male rubber core 13 and play a positioning role for the male rubber core 13.

[0088] Furthermore, in one embodiment, the first male terminal 121 and the second male terminal 122 are respectively flat and parallel to each other. In this way, the first male terminal 121 and the second male terminal 122 can simultaneously mate with other female terminals 3.

[0089] Furthermore, in one embodiment, the first male end 121 is perpendicular to the conductive connection portion 123, and / or the second male end 122 is perpendicular to the conductive connection portion 123. Thus, when the first male end 121 is inserted into the female terminal 3, the first male end 121 is less likely to bend; similarly, when the second male end 122 is inserted into the female terminal 3, the second male end 122 is less likely to bend.

[0090] Further, please refer to Figures 1 to 26 As a specific embodiment of the switch provided by the present invention, it further includes a bolt 151 and a nut seat 152 for threaded connection with the bolt 151; a locking hole is provided on the conductive connection part 123, and a mounting hole 132 adapted to the shape of the nut seat 152 is provided on the male rubber core 13, and the nut seat 152 is embedded in the mounting hole 132; the bolt 151 passes through the locking hole and is threadedly connected to the nut seat 152. Thus, the first male end 121 and the second male end 122 are located on the conductive connection part 123. When installing the first male end 121 or the second male end 122, the bolt 151 passes through the locking hole on the conductive connection part 123 and is threadedly connected to the nut seat 152 on the male rubber core 13; the nut seat 152 embedded in the mounting hole 132 can maintain a firm connection with the male rubber core 13, and the first male end 121 is fixed to the nut seat 152 by the bolt 151, which makes the connection between the first male end 121 and the male rubber core 13 very firm.

[0091] Optionally, mounting hole 132 can be a blind hole / channel.

[0092] Furthermore, in one embodiment, the conductive connection portion 123, the first male terminal 121, and the second male terminal 122 are integrally molded copper parts.

[0093] Furthermore, in one embodiment, there are two first male ends 121 and two first mounting holes 131; the two first male ends 121 correspond one-to-one with the two first mounting holes 131.

[0094] Furthermore, in one embodiment, the keyhole is located in the central region of the conductive connection portion 123. Thus, when the bolt 151 passes through the keyhole to fix the conductive connection portion 123 to the male core 13, the external force on the conductive connection portion 123 is transmitted to the bolt 151 passing through the keyhole, making it less prone to deformation.

[0095] Furthermore, in one embodiment, the first male end 121 has a rectangular cross-section. This facilitates processing.

[0096] Furthermore, in one embodiment, a strip groove 611 is formed on the outer surface of the nut seat 152, and a protrusion that mates with the strip groove 611 is formed on the inner wall of the mounting hole 132. In this way, when the nut seat 152 is engaged in the mounting hole 132, the engagement of the strip groove 611 and the protrusion makes it less likely for the nut seat 152 to slip in the mounting hole 132.

[0097] Furthermore, in one embodiment, both the first male terminal 121 and the second male terminal 122 are flat. Thus, the flat first male terminal 121 and the flat second male terminal 122 can easily mate with the female terminal 3, and are easy to process and have low cost.

[0098] Furthermore, in one embodiment, the thickness of the first male end 121 is the same as the thickness of the second male end 122. This makes it easy to manufacture and reduces costs.

[0099] Furthermore, in one embodiment, the inner wall of the first male end 121 is smoothly connected to the inner wall of the conductive connection portion 123. This makes the inner walls of the first male end 121 and the conductive connection portion 123 easier to process, and facilitates the transfer of deformation of the first male end 121 under external force to the conductive connection portion 123.

[0100] Furthermore, in one embodiment, the inner wall of the second male end 122 is smoothly connected to the inner wall of the conductive connection portion 123. This makes the inner walls of the second male end 122 and the conductive connection portion 123 easier to process, and facilitates the transfer of deformation of the second male end 122 under external force to the conductive connection portion 123.

[0101] Furthermore, in one embodiment, the edge of the first male terminal 121 facing away from the conductive connection portion 123 is chamfered, and / or the edge of the second male terminal 122 facing away from the conductive connection portion 123 is chamfered. Thus, the first male terminal 121 is more easily inserted into the female socket with the guidance of the chamfer, and similarly, the second male terminal 122 is more easily inserted into the female socket with the guidance of the chamfer.

[0102] Furthermore, in one embodiment, the first male terminal 121, the second male terminal 122, and the conductive connection portion 123 are integrally formed parts.

[0103] Furthermore, in one embodiment, the conductive connection portion 123 is provided with a bolt 151 for fixing the conductive connection portion 123 to the upper housing 11. In this way, the bolt 151 facilitates the installation and removal of the male terminal.

[0104] Furthermore, in one embodiment, bolt 151 is a screw. This makes screw tightening very convenient.

[0105] Furthermore, in one embodiment, each female terminal 3 includes a conductive base 31 and a conductive spring 32 disposed on the conductive base 31 for contacting the first male terminal 121 / second male terminal 122.

[0106] Further, in one embodiment, the conductive base 31 includes a first conductive sheet 311 and a second conductive sheet 312; the first conductive sheet 311 includes a first base plate 3111 and a first side plate 3112 fixedly connected to each other, and the second conductive sheet 312 includes a second base plate 3121 and a second side plate 3122 fixedly connected to each other; the bottom surface of the second base plate 3121 abuts against the top surface of the first base plate 3111; a receiving cavity 324 with an opening 3241 is formed between the first side plate 3112 and the second side plate 3122, and the conductive spring sheet 32 ​​is disposed in the receiving cavity 324. Thus, the second base plate 3121 abuts against the first base plate 3111. When the first base plate 3111 and the second base plate 3121 are squeezed, they are not easily separated from each other. Moreover, the first base plate 3111 and the second base plate 3121 share the pressure and are not easily deformed. The conductive spring 32 is housed in the accommodating cavity 324 formed between the first side plate 3112 and the second side plate 3122. External objects (such as male terminals) can enter the accommodating cavity 324 through the opening 3241 and come into contact with the conductive spring 32, saving the space occupied by the conductive spring 32. Furthermore, the first side plate 3112 and the second side plate 3122 protect the conductive spring 32 from the influence of external objects.

[0107] Optionally, in one embodiment, the first side plate 3112 and the second side plate 3122 are fixedly connected.

[0108] Optionally, in one embodiment, the conductive spring 32 is fixed on the first side plate 3112 or the second side plate 3122.

[0109] Optionally, in one embodiment, the first base plate 3111, the first side plate 3112, the second base plate 3121, the second side plate 3122, and the conductive spring 32 are all made of copper.

[0110] Furthermore, in one embodiment, the first base plate 3111 and the first side plate 3112 are arranged perpendicularly. In this way, the first base plate 3111 and the first side plate 3112 are easier to bend and form; and when the first side plate 3112 is subjected to a pushing / pulling force from the conductive spring 32 toward the first side plate 3112, the first side plate 3112 is less likely to deform during the process of the first base plate 3111 supporting the first side plate 3112.

[0111] Furthermore, in one embodiment, the first base plate 3111 and the first side plate 3112 are smoothly connected. This prevents breakage during stress transfer between the first base plate 3111 and the first side plate 3112.

[0112] Furthermore, in one embodiment, the second base plate 3121 is perpendicular to the second side plate 3122. This makes it easier to bend and form the second base plate 3121 and the second side plate 3122; and when the second side plate 3122 is subjected to a pushing / pulling force from the conductive spring 32 in the direction of the second side plate 3122, the second side plate 3122 is less prone to deformation during the process of the second base plate 3121 supporting the second side plate 3122.

[0113] Furthermore, in one embodiment, the second base plate 3121 and the second side plate 3122 are smoothly connected. This prevents breakage during stress transfer between the first base plate 3111 and the first side plate 3112.

[0114] Furthermore, in one embodiment, the thickness of the first base plate 3111 is the same as the thickness of the second base plate 3121. In this way, the first base plate 3111 and the second base plate 3121 can maintain more consistent deformation when subjected to external forces.

[0115] Furthermore, in one embodiment, the thickness of the first side plate 3112 is the same as the thickness of the second side plate 3122. In this way, the first side plate 3112 and the second side plate 3122 can maintain more consistent deformation when subjected to external forces.

[0116] Furthermore, in one embodiment, a protrusion 3251 is provided on the first side plate 3112, and a positioning hole 3252 is provided on the second side plate 3122, with the protrusion 3251 being engaged within the positioning hole 3252. Thus, the protrusion 3251 being engaged within the positioning hole 3252 maintains the stability of the relative position between the first side plate 3112 and the second side plate 3122.

[0117] Furthermore, in one embodiment, the protrusion 3251 and the positioning hole 3252 have the same cross-section, and the cross-sections of the protrusion 3251 and the positioning hole 3252 are rectangular. Thus, the rectangular protrusion 3251, when engaged within the positioning hole 3252, is less prone to rotation.

[0118] Furthermore, in one embodiment, the first conductive sheet 311 and the second conductive sheet 312 are integrally formed. Thus, the first conductive sheet 311 and the second conductive sheet 312 have stronger resistance to bending.

[0119] Further, in one embodiment, the conductive spring sheet 32 ​​includes a first mounting plate 321, a second mounting plate 322 spaced apart from the first mounting plate 321, and a sheet body 323 located between the first mounting plate 321 and the second mounting plate 322. One end of the sheet body 323 is connected to the first mounting plate 321, and the other end of the sheet body 323 is connected to the second mounting plate 322. The sheet body 323 has a first side surface 3231 and a second side surface 3232 facing each other. The sheet body 323 protrudes in the direction of the first side surface 3231 so that the second side surface 3232 is recessed to form a buffer cavity 3233. Thus, the sheet 323 can be easily installed in the required position via the first mounting plate 321 and the second mounting plate 322. The first mounting plate 321 and the second mounting plate 322 provide support for the sheet 323, and the external force on the sheet 323 is distributed to the first mounting plate 321 and the second mounting plate 322. The sheet 323 is easy to recover after bending under the action of external force. When an external object (such as the male terminal of the plug 12) comes into contact with the sheet 323, the sheet 323 is in a raised state, and the second side surface 3232 is recessed to form a buffer cavity 3233. The buffer cavity 3233 can release the deformation of the sheet 323, which is conducive to the sheet 323 recovering its shape.

[0120] Furthermore, in one embodiment, the first side surface 3231 is curved. This makes it less likely for external objects to be obstructed when they come into contact with the first side surface 3231.

[0121] Furthermore, in one embodiment, a notch 3234 is provided on the sheet 323. In this way, the notch 3234 can release the stress that occurs when the sheet 323 deforms, and the notch 3234 can also buffer the deformation of the sheet 323.

[0122] Furthermore, in one embodiment, the first mounting plate 321, the second mounting plate 322, and the sheet 323 are integrally molded copper components. This ensures that copper has good electrical conductivity.

[0123] Furthermore, in one embodiment, a rivet 33 is also included. The conductive spring 32 is attached to the inner wall of the accommodating cavity 324. The conductive spring 32 has a first through hole, and the conductive base 31 has a second through hole. The rivet 33 passes through the first through hole and the second through hole in sequence and fixes the conductive spring 32 and the conductive base 31 together. In this way, the rivet 33 passes through the first through hole and the second through hole in sequence, and the rivet 33 fixes the conductive spring 32 to the conductive base 31. The installation process is very convenient and quick, and the conductive spring 32 can also be firmly fixed to the conductive base 31. The conductive spring 32 is attached to the inner wall of the accommodating cavity 324. When an external object (such as the male terminal of the plug 12) is inserted into the accommodating cavity 324 through the opening 3241 and makes conductive contact with the conductive spring 32, the conductive spring 32 is pressed against the inner wall of the accommodating cavity 324, and the conductive spring 32 is not easy to move or loosen.

[0124] Furthermore, in one embodiment, the conductive spring 32 includes a first mounting plate 321 attached to the inner wall of the accommodating cavity 324 and a sheet 323 disposed on the first mounting plate 321 and protruding into the accommodating cavity 324, with each first through hole respectively formed on the first mounting plate 321. Thus, the first mounting plate 321 is attached to the inner wall of the accommodating cavity 324, facilitating the stability of the positions of the first mounting plate 321 and the conductive spring 32 relative to the inner wall of the accommodating cavity 324; the sheet 323 protruding into the accommodating cavity 324 facilitates contact with objects inserted into or outside the accommodating cavity 324 through the opening 3241.

[0125] Furthermore, in one embodiment, a recess 211 is provided on the bottom wall of the accommodating cavity 21, and the bottom end of the conductive base 31 is engaged in the recess 211. In this way, the female terminal 3 can be fixed on the conductive base 31, and the conductive base 31 provides support for the female terminal 3; the bottom end of the conductive base 31 is engaged in the recess 211, and when the conductive base 31 vibrates, the conductive base 31 is not easily loosened due to the restriction of the inner wall of the recess 211.

[0126] Furthermore, in one embodiment, a through hole 2111 is provided on the bottom wall of the recess 211, and a screw is provided on the conductive base 31, with the screw passing through the through hole 2111. In this way, an external cable can be electrically connected to the conductive base 31 through the screw.

[0127] Furthermore, in one embodiment, the conductive base 31 is provided with a protrusion 34, and a groove 212 communicating with the recess 211 is recessed in the bottom wall of the receiving cavity 21, with the protrusion 34 engaged in the groove 212. Thus, the protrusion 34 being engaged in the groove 212 allows the conductive base 31 to be more firmly fixed within the receiving cavity 21, reducing the shaking of the conductive base 31.

[0128] Furthermore, in one embodiment, there are two protrusions 34 and two slots 212, with each protrusion 34 corresponding to one slot 212. Thus, the cooperation between the two protrusions 34 and the two slots 212 enhances the stability of the conductive base 31.

[0129] Furthermore, in one embodiment, the two protrusions 34 are located at opposite ends of the conductive base 31. Thus, with the two protrusions 34 located at opposite ends of the conductive base 31, the two protrusions 34 can more evenly constrain the conductive base 31.

[0130] Furthermore, in one embodiment, the cross-section of each protrusion 34 is rectangular. This makes it less likely for relative rotation to occur when the rectangular protrusion 34 engages with the slot 212.

[0131] Furthermore, in one embodiment, it also includes a female rubber core 22 inserted into the receiving cavity 21; a conductive base 31 is clamped between the female rubber core 22 and the bottom wall of the receiving cavity 21; a buckle 35 is provided on the inner wall of the receiving cavity 21, and a latch 36 for the buckle 35 to be caught on the outer surface of the female rubber core 22. In this way, the conductive spring 32 is disposed on the conductive base 31, and the female rubber core 22 is inserted into the receiving cavity 21. The conductive base 31 is clamped and positioned by the female rubber core 22 and the inner wall of the receiving cavity 21 to reduce the loosening of the female terminal 3; during the process of inserting the female rubber core 22 into the receiving cavity 21, the buckle 35 on the female rubber core 22 is caught on the latch 36 on the inner wall of the receiving cavity 21 to prevent the female rubber core 22 from loosening, further reducing the loosening of the female terminal 3.

[0132] Furthermore, in one embodiment, a second mounting hole 221 is provided on the female core 22, and the female terminal 3 is inserted into the second mounting hole 221. In this way, the female terminal 3 passes through the second mounting hole 221, and the second mounting hole 221 can limit the position of the female terminal 3, which is beneficial to the stability of the female terminal 3.

[0133] Furthermore, in one embodiment, the conductive base 31 is flat. Thus, the flat conductive base 31 facilitates clamping between the mother core 22 and the inner wall of the accommodating cavity 21.

[0134] Furthermore, in one embodiment, the conductive base 31 is perpendicular to the insertion direction of the mother core 22. Thus, the abutment force exerted by the mother core 22 on the conductive base 31 is perpendicular to the conductive base 31, reducing the likelihood of bending of the conductive base 31.

[0135] Furthermore, in one embodiment, the inverted buckle 35 is a protrusion provided on the inner wall of the accommodating cavity 21, and the buckle position 36 is a recessed portion 211 formed by the recess on the outer surface of the female core 22; the protrusion is engaged in the recessed portion 211. In this way, positioning can be completed simply by engaging the protrusion in the recessed portion 211, which is very convenient.
