[0059] As described in the background art, when wiring on-site for existing explosion-proof connectors, the junction box needs to be opened. Wiring personnel need to wind the wires around the terminal posts inside the junction box to complete the wiring, resulting in low on-site wiring efficiency. Moreover, the on-site wiring is in an explosive gas environment, and an explosion transmission phenomenon will occur in the case of live misoperation. In addition, when replacing the load, the entire junction box needs to be replaced, resulting in a relatively high maintenance cost.

[0060] Based on this, an embodiment of the present application provides an explosion-proof connector, which includes a plug, a socket, a first connection component, and a second connection component: The plug includes a housing and a first core assembly; the socket includes a mounting base and a second core assembly; the first connection component includes a boosting member, the boosting member is rotatably connected to the housing, and the boosting member is also slidably connected to the mounting base; when connecting, only the boosting member needs to be rotated relative to the housing to drive the housing and the mounting base to be plugged together, so that the first core assembly and the second core assembly are correspondingly electrically connected, and the plug and the socket can be plugged together. There is no need to open the junction box, nor to wind the wire on the terminal post, which has the effects of convenient installation and high operation efficiency, and improves the operation safety; and the second connection component includes a clamping member and a blocking member, the clamping member can be clamped with the blocking member, and can limit the connection state of the housing and the mounting base when the first core assembly and the second core assembly are correspondingly electrically connected, so as to prevent the plug and the socket from coming off. Therefore, the explosion-proof connector provided by the present application can solve the problems of complex wiring process, inconvenient wiring operation, and low wiring efficiency of the explosion-proof connector.

[0061] The technical solutions of the embodiments of the present application will be described in detail below with specific embodiments in conjunction with the accompanying drawings. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0062] Combined Figures 1 to 5 As shown, an embodiment of the present application provides an explosion-proof connector, which includes a plug 100, a socket 200, a first connection component 300, and a second connection component 400; the plug 100 includes a housing 110 and a first core assembly 120, and the first core assembly 120 is connected inside the housing 110; the socket 200 includes a mounting base 210 and a second core assembly 220, and the second core assembly 220 is connected inside the mounting base 210; the first connection component 300 includes a boosting member 310, the boosting member 310 is rotatably connected to the housing 110, and the boosting member 310 is also slidably connected to the mounting base 210; the boosting member 310 is configured to rotate relative to the housing 110 to switch between a first connection position and a second connection position; when in the first connection position, the boosting member 310 drives the housing 110 to move towards the mounting base 210 to be plugged with the mounting base 210, so that the first core assembly 120 and the second core assembly 220 are correspondingly electrically connected; when in the second connection position, the boosting member 310 drives the housing 110 to move away from the mounting base 210 to be disengaged from the mounting base 210, so that the first core assembly 120 and the second core assembly 220 are correspondingly disconnected from the electrical connection; the second connection component 400 includes a clamping member 410 and a blocking member 420, one of the clamping member 410 and the blocking member 420 is arranged on the housing 110, and the other is arranged on the mounting base 210; the clamping member 410 is configured to be clamped with the blocking member 420 when the first core assembly 120 and the second core assembly 220 are correspondingly electrically connected, so as to limit the housing 110 and the mounting base 210 from being disengaged.

[0063] In specific implementation, the boosting member 310 is rotated relative to the housing 110 to the second connection position to connect the mounting base 210 to the boosting member 310, and then the boosting member 310 is rotated from the second connection position to the first connection position to drive the relative movement of the housing 110 and the mounting base 210 for insertion, so as to drive the corresponding insertion of the first core assembly 120 inside the housing 110 and the second core assembly 220 inside the mounting base 210 to achieve electrical connection, thereby realizing the insertion connection between the plug 100 and the socket 200, which can solve the problems of complex wiring process and inconvenient operation in the wiring process of the explosion-proof connector, and improve the wiring efficiency of on-site operators.

[0064] The explosion-proof connector has relatively high requirements for contact pressure and sealing, and is in the form of multi-point contact insertion. Therefore, the plugging and unplugging operations during the installation of the explosion-proof connector are relatively laborious, and the installation difficulty is also relatively large when the operating space is limited. In the embodiment of the present application, by providing the boosting member 310 on the plug 100, during the installation process of the explosion-proof connector, only by operating the boosting member 310 to rotate relative to the housing 110, the housing 110 and the mounting base 210 can be driven to be inserted, so that the first core assembly 120 and the second core assembly 220 are correspondingly electrically connected, having the effect of convenient installation.

[0065] When the boosting member 310 is in the first connection position, the operator needs to maintain the current position of the boosting member 310 to prevent the boosting member 310 from rebounding to the second connection position, resulting in the disconnection of the plug 100 and the socket 200. Through the provided clamping member 410 and the blocking member 420, the plug 100 and the socket 200 can be clamped to each other when the plug 100 and the socket 200 are inserted in place, so as to limit the connection state of the plug 100 and the socket 200 and avoid the accidental disconnection of the plug 100 and the socket 200.

[0066] It can be seen that for the connector provided in the embodiment of the present application, by providing the boosting member 310 on the plug 100, when the plug 100 and the socket 200 are inserted, the operator does not need to open the junction box for wiring operation, nor directly contact the wire and the connection terminal. Only by operating the boosting member 310 to rotate relative to the housing 110, the plug 100 and the socket 200 can be driven to be inserted or disengaged, improving the operation safety and having the effect of convenient installation.

[0067] Moreover, when inserted in place, the clamping member 410 can be engaged with the blocking member 420, which can automatically limit the connection state of the housing 110 and the mounting base 210, avoid the accidental disconnection of the plug 100 and the socket 200, and improve the connection stability between the plug 100 and the socket 200.

[0068] When it is necessary to replace the load, there is no need to replace the entire junction box. It is only necessary to reconnect the plug 100 and the socket 200, that is, only to reconnect the plug 100 on the replaced device to the socket 200, which improves the convenience of maintenance and can reduce the maintenance cost.

[0069] Combined with Figure 2 As shown, in some embodiments, the boosting member 310 includes an operating rod 311 and at least one swing arm 312. The operating rod 311 is connected to the swing arm 312; a first connecting portion 111 is provided on the housing 110, and the swing arm 312 is rotatably connected to the first connecting portion 111; a second connecting portion 211 is provided on the mounting base 210, and the swing arm 312 is also slidably connected to the second connecting portion 211.

[0070] Wherein, one end of the swing arm 312 is connected to the first connecting portion 111, and the other end of the swing arm 312 is connected to the operating rod 311. The first connecting portion 111 is provided on the outer side wall of the housing 110, and a first connecting hole 3123 is correspondingly provided on the swing arm 312. The first connecting portion 111 is inserted into the first connecting hole 3123, and the swing arm 312 can rotate around Figure 1 the Y direction in it to rotate relative to the housing 110.

[0071] When it is necessary to disassemble the plug 100 from the socket 200, it is only necessary to switch the boosting member 310 from the first connection position to the second connection position. By rotating the operating rod 311 to move away from the housing 110, driving the swing arm 312 to rotate, the housing 110 can be driven to move away from the mounting base 210 and be disengaged from the plug-in connection with the mounting base 210.

[0072] When it is necessary to install the plug 100 onto the socket 200, it is only necessary to switch the boosting member 310 from the second connection position to the first connection position. By rotating the operating rod 311 to move towards the housing 110, driving the swing arm 312 to rotate, the housing 110 can be driven to move towards the mounting base 210 and be plugged into the mounting base 210.

[0073] It can be seen that by providing the boosting member 310, there is no need to strongly pull out the plug 100. It is only necessary to rotate the boosting member 310 to achieve the installation and disassembly of the plug 100 and the socket 200, reducing the operation difficulty and improving the convenience of installing the plug 100.

[0074] Combined with Figure 2 and Figure 4 As shown, in some embodiments, the first connecting portion 111 is a pivot; the second connecting portion 211 is a convex block, and a sliding groove 3121 is formed on the swing arm 312, and the convex block is embedded in the sliding groove 3121.

[0075] Wherein, the sliding groove 3121 is arc-shaped, and an entrance and exit 3122 is provided at one end of the sliding groove 3121.

[0076] In specific implementation, when the boosting member 310 rotates to the second connection position, the inlet / outlet 3122 faces the socket 200, and the bump can enter the chute 3121 through the inlet / outlet 3122.

[0077] When the boosting member 310 rotates from the second connection position to the first connection position, the swing arm 312 rotates to move the chute 3121, so that the bump slides in the chute 3121, and can drive the housing 110 to approach the mounting base 210 and insert into the mounting base 210.

[0078] By providing the arc-shaped chute 3121, during the rotation of the swing arm 312, the bump can be driven to linearly move along the insertion direction of the plug 100 and the socket 200 (i.e., Figure 1 the X direction in

[0079] In some embodiments, the first connection assembly 300 further includes a connecting member 320. The connecting member 320 is used to connect the boosting member 310 and the housing 110 when the first core assembly 120 and the second core assembly 220 are correspondingly electrically connected, so as to limit the rotation of the boosting member 310 relative to the housing 110.

[0080] Wherein, the connecting member 320 is a structure capable of fixing the boosting member 310 and the housing 110. The specific structure of the connecting member 320 in the embodiments of the present application is not limited in any way, as long as it can achieve the stable connection of the boosting member 310 and the housing 110, so that the boosting member 310 is maintained at the first connection position, that is, it is within the protection scope of the embodiments of the present application.

[0081] Combined with Figure 2 shown, exemplarily, the connecting member 320 is a threaded fastener, such as a screw.

[0082] Wherein, a first mounting hole 3111 is provided on the operating rod 311 of the boosting member 310, and a second mounting hole 115 is provided on the housing 110. In specific implementation, the connecting member 320 is inserted into the second mounting hole 115 through the first mounting hole 3111 and is connected to the second mounting hole 115 by thread fitting to fixedly connect the boosting member 310 and the housing 110, and limit the rotation of the boosting member 310 relative to the housing 110, so that the boosting member 310 is maintained at the first connection position to maintain the stable connection of the plug 100 and the socket 200.

[0083] Combined with Figure 3 shown, in some other embodiments, the connecting member 320 can also be a sliding member, such as a plug block.

[0084] Among them, a first slot is provided on the operating rod 311 of the boosting member 310, and a second slot is provided on the housing 110. In a specific implementation, when the boosting member 310 is in the first connection position, the positions of the first slot and the second slot correspond, and their extending directions are the same. The insertion block can slide in the first slot and the second slot to be inserted into both the first slot and the second slot simultaneously, so as to fixedly connect the boosting member 310 to the housing 110, restrict the rotation of the boosting member 310 relative to the housing 110, keep the boosting member 310 in the first connection position, and maintain the stable connection between the plug 100 and the socket 200.

[0085] Furthermore, the cross-sectional shape of the insertion block is adapted to the cross-sectional shapes of the first slot and the second slot. Exemplarily, the cross-section of the insertion block can be dovetail-shaped, arc-shaped, I-shaped, etc., so that the insertion block can slide along the extending direction of the first slot and the second slot, and restrict the insertion block from disengaging from the first slot and the second slot in a direction perpendicular to the extending direction of the first slot and the second slot.

[0086] In some other embodiments, the connecting member 320 can also be a plug pin.

[0087] Correspondingly, a first insertion hole is formed in the boosting member 310, and a second insertion hole is formed in the housing 110. In a specific implementation, when the boosting member 310 is in the first connection position, the positions of the first insertion hole and the second insertion hole correspond, and the connecting member 320 is inserted into the second insertion hole through the first insertion hole.

[0088] Combined with Figure 3 As shown in the figure, in some embodiments, the clamping member 410 is a first convex, and the blocking member 420 is a clamping groove, and the first convex is clamped in the clamping groove.

[0089] It should be noted that the housing 110 is located on the outer surface of the plug 100 and can be made of an insulating material (such as plastic, ceramic) or a metal material (such as aluminum). When the housing 110 is made of an insulating material, the corresponding mounting seat 210 is also made of an insulating material; when the housing 110 is made of a metal material, the outer shell of the corresponding socket 200 is also made of a metal material to provide effective mechanical strength and electrical insulation.

[0090] Exemplarily, when both the housing 110 and the mounting seat 210 are made of an insulating material (such as plastic), the first convex can be provided on the housing 110, and the clamping groove can be provided on the mounting seat 210.

[0091] Among them, a clamping block is provided on the outer side of the housing 110. One end of the clamping block is a fixed end, and the fixed end is connected to the housing 110. The other end of the clamping block is a movable end, and the first convex is provided on the surface of the clamping block facing away from the housing 110. An abutting block 411 slidably connected to the housing 110 is also provided on the outer side of the housing 110, and the abutting block 411 is located at the movable end of the clamping block.

[0092] An abutting portion 214 is provided on the outer side of the mounting base 210, and the card slot is formed on the abutting portion 214.

[0093] When the housing 110 is inserted into the mounting base 210, the position of the abutting portion 214 on the mounting base 210 corresponds to that of the clamping block on the housing 110, and the abutting portion 214 is located on the side of the clamping block away from the housing 110, and the first convex can be embedded in the card slot.

[0094] When the first plug-in core assembly 120 and the second plug-in core assembly 220 are correspondingly electrically connected, the abutting block 411 is slid towards the clamping block, so that the abutting block 411 moves to between the clamping block and the housing 110 through the movable end of the clamping block. The abutting block 411 can lift the movable end of the clamping block, so that the clamping block abuts against the abutting portion 214, so as to lift the first convex.

[0095] When the housing 110 and the mounting base 210 tend to be separated, the first convex can be blocked at the end of the card slot to limit the separation of the housing 110 and the mounting base 210, thereby avoiding accidental disconnection of the plug 100 and the socket 200.

[0096] Combined Figure 1 、 Figure 2 and Figure 4 As shown in, in some other embodiments, the clamping member 410 is an elastic hook, and the blocking member 420 is a second convex, and the elastic hook is clamped on the second convex.

[0097] Exemplarily, when both the housing 110 and the mounting base 210 are made of a metal material (such as aluminum), the second convex can be provided on the housing 110, and the elastic hook can be provided on the mounting base 210.

[0098] Wherein, an abutting portion 214 is provided on the outer side of the mounting base 210, and the elastic hook is connected to the side of the abutting portion 214 facing the mounting base 210.

[0099] When the housing 110 is inserted into the mounting base 210, the positions of the elastic hook and the second convex correspond to each other, and the two move towards each other along with the insertion action of the mounting base 210 and the housing 110. When the first plug-in core assembly 120 and the second plug-in core assembly 220 are correspondingly electrically connected, the hook head of the elastic hook can be clamped on the side of the second convex away from the mounting base 210. After the elastic hook and the second convex are clamped, the plug and the socket cannot be separated without using a tool to lift the elastic hook.

[0100] When the housing 110 and the mounting base 210 tend to be separated, under the connection action of the elastic hook and the second convex, the separation of the housing 110 and the mounting base 210 can be restricted, thereby avoiding accidental disconnection of the plug 100 and the socket 200.

[0101] Specifically, after the plug 100 and the socket 200 are inserted in place under the drive of the boosting member 310, the second connection component 400 can initially lock the connection between the plug 100 and the socket 200, avoiding accidental opening of the boosting member 310, which is convenient for the operator to install the connection member 320.

[0102] Combined with the connection member 320 in the first connection component 300, it can connect the boosting member 310 and the housing 110, hold the boosting member 310 in the first connection position, and further lock the connection between the plug 100 and the socket 200, further improving the connection stability between the plug 100 and the socket 200.

[0103] It can be seen that in the embodiment of the present application, by setting the first connection component 300 and the second connection component 400, the plug 100 and the socket 200 are fixed in a double-locking manner, and the anti-disconnection effect is good, which helps to ensure the electrical contact of the explosion-proof connector and improve the use safety.

[0104] Combined Figure 5 and Figure 6 As shown, in some embodiments, the first core component 120 includes a first connection base 121, a first core 122, and a first protective sleeve 123; the first connection base 121 is detachably installed in the housing 110; the first core 122 is connected in the first connection base 121; the first protective sleeve 123 is sleeved outside the first connection base 121; the first protective sleeve 123 and the first connection base 121 are of an integral structure.

[0105] By detachably installing the first connection base 121 in the housing 110, when the first core component 120 is damaged or fails, it is not necessary to replace the entire plug 100 or perform relatively complex repairs. It only needs to replace the first core component 120, which reduces the maintenance difficulty. In addition, the replacement of the male core component and the female core component can also be realized, improving the flexibility and applicability.

[0106] Furthermore, the first core 122 includes at least one pin. When the first core 122 is a male core, the pin is a male pin; when the first core 122 is a female core, the pin is a female pin.

[0107] The pin with the riveted elastic piece is pressed into the first connection base 121 by a press, so that the pin and the first connection base 121 are in interference fit. When the wire is inserted into the first connection base 121, the elastic piece is squeezed to deform, and under the pressing action of the elastic piece, the wire can be kept connected with the pin.

[0108] The first insert component 120 further includes a first end cap 124. The first end cap 124 is connected to one end of the first connection base 121 where the wire is connected. At least one first driving member 125 is further disposed in the first connection base 121. The first driving members 125 correspond to the pins one by one and are connected to the first end cap 124.

[0109] When the first driving member 125 moves towards the pin, it can abut against the elastic piece riveted on the pin to drive the elastic piece away from the pin, so as to release the pressing effect on the wire. At this time, the wire can be taken out from the first connection base 121.

[0110] When the first driving member 125 moves away from the pin, it can be disengaged from abutting against the elastic piece riveted on the pin, and the elastic piece rebounds to press the wire again, so that the wire is connected to the pin again. By providing the first driving member 125, it is convenient to replace the wire connected to the first insert component 120.

[0111] Exemplarily, the first protective sleeve 123 is a copper ring, and the copper ring is connected to the first connection base 121 by means of overmolding or glue bonding to form an integral structure.

[0112] Combined Figure 7 As shown, in some embodiments, the second insert component 220 includes a second connection base 221, a second insert 222 and a second protective sleeve 223; the second connection base 221 is detachably installed in the mounting base 210; the second insert 222 is connected in the second connection base 221; the second protective sleeve 223 is sleeved outside the second connection base 221; the second protective sleeve 223 and the second connection base 221 are of an integral structure.

[0113] By detachably installing the second connection base 221 in the housing 110, when the second insert component 220 is damaged or fails, it is not necessary to replace the entire socket 200 or perform relatively complex repairs. Only the second insert component 220 needs to be replaced, which reduces the maintenance difficulty. In addition, the replacement of the male insert component and the female insert component can also be realized, improving flexibility and applicability.

[0114] Further, the second insert 222 also includes at least one pin. The pins of the second insert 222 correspond to the pins of the first insert 122 one by one. When the second insert 222 is a male insert, the pins are male pins; when the second insert 222 is a female insert, the pins are female pins.

[0115] The pins with the elastic pieces already riveted are pressed into the second connection base 221 by a press so that the pins are in interference fit with the second connection base 221. When the wire is inserted into the second connection base 221, the elastic piece is squeezed to deform, and under the pressing action of the elastic piece, the wire can be kept connected to the pin.

[0116] The second core assembly 220 also includes a second end cover 224 , which is connected to one end of the second connection base 221 connected to the wire. At least one second driving member 225 is also provided in the second connection base 221 . The second driving member 225 corresponds to the pin one by one and is connected to the second end cover 224 .

[0117] When the second driving member 225 moves toward the plug pin, it can abut against the spring sheet riveted on the plug pin to drive the spring sheet away from the plug pin to release the pressing effect on the wire. At this time, the wire can be taken out from the second connecting seat 221.

[0118] When the second driving member 225 moves away from the plug pin, it can be disengaged from the spring sheet riveted on the plug pin, and the spring sheet rebounds and re-compresses the cable to reconnect the wire to the plug pin. The second driving member 225 can be easily replaced with the wire connected to the second plug assembly 220.

[0119] Exemplarily, the second protective sleeve 223 is a copper ring, which is connected to the second connecting seat 221 by means of overmolding or gluing to form an integrated structure.

[0120] In some embodiments, one of the first ferrule 122 and the second ferrule 222 is a male ferrule and the other is a female ferrule, and the male ferrule and the female ferrule can be interchanged; when the housing 110 and the mounting base 210 are plugged in, the first ferrule 122 is electrically connected to the second ferrule 222, and the first protective sleeve 123 is plugged in to the second protective sleeve 223.

[0121] By providing the first protection sleeve 123 and the second protection sleeve 223 , explosion-proof protection can be provided for the first ferrule 122 and the second ferrule 222 inside.

[0122] In addition, after the first protective sleeve 123 and the second protective sleeve 223 are correspondingly plugged in, it is equivalent to providing two layers of protective sleeves outside the first plug core 122 and the second plug core 222, which greatly improves the flameproof protection effect.

[0123] Combination Figure 1 and Figure 2 As shown, in some embodiments, the housing 110 has a plug-in end 112 , and the plug-in end 112 is provided with an engaging groove 113 for accommodating the mounting seat 210 , and a sealing member 114 is provided on the side wall of the engaging groove 113 .

[0124] One end of the first ferrule 122 and the second ferrule 222 are both wiring terminals, which are used to connect wires. The ends of the first ferrule 122 and the second ferrule 222 facing away from the wiring terminals are used to be plugged into each other to achieve electrical connection.

[0125] The connection end of the first ferrule 122 is disposed toward an end of the housing 110 away from the plug-in end 112 , and the end of the first ferrule 122 away from the connection end is disposed toward the plug-in end 112 of the housing 110 .

[0126] The shape of the end of the mounting seat 210 is adapted to the fitting groove 113 , and the end of the mounting seat 210 can be inserted into the fitting groove 113 . When the mounting seat 210 is inserted into the fitting groove 113 , the sealing member 114 abuts against the inner wall of the mounting seat 210 .

[0127] The sealing member 114 can be provided to seal the plug-in connection portion between the housing 110 and the mounting seat 210 , thereby providing a better waterproof and anti-fouling effect to the first plug core 122 and the second plug core 222 inside.

[0128] In addition, by arranging the sealing member 114 at the plug-in end 112 of the housing 110, the housing 110 can provide an effective sealing effect when it is initially plugged into the mounting seat 210 until it is disconnected from the mounting seat 210, thereby improving the protective effect.

[0129] The flameproof connector provided in the embodiment of the present application has a flameproof function realized by the internal first protective sleeve 123 and the second protective sleeve 223, and a sealing function realized by the housing 110, the mounting seat 210 and the sealing member 114. This flameproof and sealing are realized independently, which helps to reduce the plugging and unplugging force of the plug 100 and the socket 200 during the plugging and unplugging process, and reduces the installation difficulty of the flameproof connector. In addition, when the internal first plug 122 and the second plug 222 are not fully connected or not fully disconnected, the external housing 110 and the mounting seat 210 can both achieve sealing, thereby improving the protection effect.

[0130] Furthermore, one end of the housing 110 away from the plug-in end 112 is connected to a cable connector 130 , and the wire enters the housing 110 through the cable connector 130 .

[0131] Among them, the cable connector 130 includes a gland head 131, a gland sealing ring 132 and a sealing ring claw 133. An installation connector is provided on the end face of the shell 110 away from the plug-in end 112. The gland sealing ring 132 is installed in the sealing ring claw 133, and the sealing ring claw 133 is installed in the gland head 131. The gland head 131 is connected to the installation connector through threaded matching.

[0132] Before the plug 100 is plugged into the socket 200, the wires to be connected to the junction box are preset on the plug 100. The wires enter the housing 110 through the cable connector 130 to be connected to the first ferrule assembly 120. By setting the cable connector 130, the wires can be protected.

[0134] Specifically, the distribution terminal block 510 is connected to the pins of the second insert component 220 through wires.

[0135] The output end of the distribution terminal block 510 can have one, two or three, etc., so as to form a layout form such as one-in-one-out, one-in-two-out or one-in-three-out.

[0136] The socket 200 connected to the input end of the distribution terminal block 510 is the input end, which is used to connect to the plug 100 corresponding to the device at the input end; the socket 200 connected to the output end of the distribution terminal block 510 is the output end, which is used to connect to the plug 100 corresponding to the device at the output end.

[0137] Exemplarily, different color or shape marks can be set at the input end and output end of the distribution terminal block 510 to distinguish different electrodes; correspondingly, the sockets 200 located outside the distribution box 500 can distinguish the input end and output end by the male and female of the pins. For example, the socket 200 with female pins is the output end, and the socket with male pins is the input end.

[0138] Among them, the distribution box 500 includes a box body 520 and a box cover 530. A first installation opening 521 for the distribution terminal block 510 to enter and exit is provided on the box body 520. A sealing groove 522 is provided on the periphery of the first installation opening 521, and a first sealing ring 523 is arranged in the sealing groove 522. The box cover 530 is covered at the first installation opening 521, the box cover 530 abuts against the first sealing ring 523, and the box cover 530 is connected to the box body 520 through a first fastening screw 540.
