Description

Technical Field

[0001] The present invention relates to the technical field of electrical connection, and more specifically, to an orbital power distribution system. Background Art

[0002] A cabinet power distribution unit (PDU) is a power distribution manager with power distribution and management functions. The PDU power socket is the first and most closely related component for the operation of all devices. The quality of the PDU directly affects each device. The PDU is mainly used on the cabinets in data rooms, data centers, and supercomputer centers. Different specifications and functions of the PDU can be customized according to requirements to provide suitable power distribution solutions for different power environments and meet different standard requirements at home and abroad.

[0003] Currently, the general cabinet power socket is an integrated structure, composed of multiple sockets and multiple functional modules. The sockets can be three-hole or five-hole, and the functional modules such as lightning protection modules, intelligent electricity meters, double-break switches, etc. Each socket and functional module are arranged closely in sequence. Three wires (live wire, neutral wire, ground wire) are connected to three conductive copper bars by soldering, and each socket and functional module are electrically connected through the conductive copper bars. However, defects are likely to occur in the welding joint during the welding process, such as porosity, cracks, and incomplete penetration, and then the welding joint is likely to fall off during use, and poor welding is a major cause of product defects.

[0004] At the same time, since the socket area of the current PDU is an non-detachable structure, usually when one socket is damaged, the entire PDU may need to be replaced, resulting in all connected devices being shut down, and the operation and maintenance cost is relatively high, especially for some servers that cannot stop running. In addition, compared with ordinary socket strips, the PDU socket is thicker and looks more bulky, occupying too much space in the cabinet. To prevent the situation of insufficient sockets, PDUs with more sockets than initially required are often customized, which may cause waste. If the number or position of the sockets is insufficient, the devices need to be disconnected and reconnected, causing many inconveniences in use.

[0005] In addition, for an ordinary detachable socket, there is a fixed rotation direction. However, users often confuse the insertion direction of the socket, resulting in the inability to rotate the socket. Especially for first-time users, they may try to rotate it by brute force, causing damage to the socket, which is not conducive to the installation and use of the socket on the track. The safety lock is mainly set to prevent children from removing the socket. It needs to be pressed to unlock, and then the socket can be rotated and removed. However, it is locked in the form of a pawl buckle connection. Even if the button is not pressed, when rotating it slightly forcefully, it may break through the connection of the pawl. If it is often forced to twist, it may cause complete damage and may also lead to power failure. Moreover, it is in an automatic locking mode. Once the socket is rotated in the power-on direction, it will be automatically locked. However, in the installation site of the PDU, it may not be necessary to lock it every time. When the user is unaware of or forgets the existence of the safety lock, it will cause the situation of forced twisting, which is time-consuming and laborious and reduces work efficiency.

[0044] Such as Figures 1 to 12Shown is an orbital power distribution system, which includes an orbital module 1, a socket module 50, and a functional module 40. The orbital module 1 includes a housing 10, a carrier 20, and a terminal block 30. The housing 10 includes an orbital part 11 and a slide base 12 integrally connected to the orbital part 11. The socket module 50 is detachably connected to the orbital part 11 of the housing 10. The carrier 20 is slidably connected to the slide base 12. The functional module 40 is integrally installed in the carrier 20. The terminal block 30 is installed inside the carrier 20 and extends into the slot 116 in the orbital part 11. A copper sheet conductor 115 is installed in the slot 116. The upper surface of the housing 10 and the upper surface of the carrier 20 are not in the same plane. The height of the housing 10 is less than the height of the carrier 20, so that the orbital module 1 is distributed in a three-dimensional space, which can make more efficient use of space than the two-dimensional plane distribution of traditional PDU, strengthen heat dissipation, and at the same time reduce the occupied space in the cabinet.

[0045] Among them, the height of the orbital part 11 is less than the height of the carrier 20. The height of the orbital part 11 is 20 - 30 mm, and the height of the carrier 20 and the functional module 40 is about 40 mm. The housing 10 is made of aluminum alloy, which is lighter and more beautiful than traditional PDU sockets. The overall thickness of traditional PDU sockets is about 40 mm, and the socket area and the functional module area are of the same height, so heat is likely to accumulate inside. However, due to the small size and low height of the orbital part 11 of the present invention, heat is also more easily dissipated from the lower orbital part 11 chute 111. The assembled structure of the housing 10 and the carrier 20 is also more likely to form an open heat dissipation channel.

[0046] Among them, the slide base 12 is provided with a slideway 121. The carrier 20 is provided with an inner cavity 21, an upper side wall 22, and a lower side wall 23. The upper side wall 22 is provided with an upper guiding groove 221. The functional module 40 is slidably connected to the upper guiding groove 221. The lower side wall 23 is slidably connected to the slideway 121, so that the carrier 20 can slide to the orbital part 11, and the terminal block 30 is inserted into the slot 116 of the orbital part 11 and touches the copper sheet conductor 115.

[0047] Among them, the slide base 12 is further provided with a first guide rail 122 and a second guide rail 123. The first guide rail 122 and the second guide rail 123 are respectively located on both sides of the slide base 12. The lower side wall 23 is provided with a first guide groove 231 and a second guide groove 232. The first guide groove 231 is adapted to the first guide rail 122, and the second guide groove 232 is adapted to the second guide rail 123. The groove width of the first guide groove 231 is greater than that of the second guide groove 232. The first guide rail 122 has a U-shaped structure, and the second guide rail 123 has an L-shaped structure, as Figure 5 shown. This not only facilitates the installation of the slot 116, but also facilitates the correct assembly of the carrier 20 without the occurrence of incorrect installation.

[0048] Among them, the rail part 11 is provided with a chute 111, a receiving cavity 112, a vacant cavity 113 and a limiting groove 114. The chute 111 is axially opened in the rail part 11. The receiving cavity 112 and the vacant cavity 113 are respectively located on both sides of the chute 111. The limiting groove 114 is parallel to the chute 111 and is horizontally opened above the vacant cavity 113.

[0049] Among them, the carrier frame 20 further includes a front cover plate 25 and a rear cover plate 26. The sliding seat 12 is provided with a first screw hole 124, and the upper side wall 22 is provided with a second screw hole 222. The front cover plate 25 and the rear cover plate 26 are respectively located on the front and rear sides of the second screw hole 222. The front cover plate 25 is fixed to the front side of the carrier frame 20 by a screw 125, and the rear cover plate 26 connects the first screw hole 124 and the second screw hole 222 through a screw 125.

[0050] Among them, the upper side wall 22 is provided with two pairs of guiding arms 223. The upper guiding grooves 221 are respectively located between the guiding arms 223. The width of the guiding arms 223 is suitable for the installation of the functional module 40.

[0051] Among them, Figure 11 The shown terminal 30 is provided with a box body 31 and a conductive part 32. The conductive part 32 penetrates through the box body 31. The box body 31 includes a fixing part 311 and a sliding part 312. The fixing part 311 is connected to the bottom frame 24 of the carrier frame 20 by a screw 125. The lower side wall 23 is provided with a lower guiding groove 234 and a lower channel 235. The lower guiding groove 234 is located below the first guiding groove 231. The sliding part 312 is engaged with the lower guiding groove 234. The lower guiding groove 234 and the vacant cavity 113 of the rail part 11 are directly communicated, which is convenient for the heat circulation and dissipation inside the system, avoiding heat accumulation and damaging the functional module 40. Since the rail part 11 is small in volume, it also has a chute 111 communicating with the outside, and the heat is relatively easy to dissipate outward, promoting the internal heat circulation and facilitating the heat in the carrier frame 20 to flow to the rail part 11 and then dissipate outward. Among them, the limiting groove 114 can also communicate the vacant cavity 113 and the outside.

[0052] Among them, the conductive part 32 includes a conductive insert 321, a wire 322 and a compression ring 323. The compression ring 323 is integrally connected to the conductive insert 321. The compression ring 323 is located at the rear end of the conductive insert 321 to connect the inner end of the wire 322. The conductive insert 321 extends towards the rail part 11, and the wire 322 extends towards the functional module 40 in the carrier frame 20, as Figure 12As shown, the outer end of the wire 322 is connected to the adjacent functional module 40, shortening the wiring length, enabling the terminal to be electrically connected to the functional module 40, and reducing the generation of heat in the wire 322. Thus, effectively avoiding the existence of solder joints between the terminal 30 and the copper sheet conductor 115. By adding an installation process for the terminal 30, the wire 322 is routed from the side to connect to the adjacent functional module 40, improving the electrical connection stability between the copper sheet conductor 115 and the functional module 40, making the connection more secure, and also effectively avoiding the electrical connection of the terminal by riveting. Riveting will cause the temperature of the rivet to be too high during use and fail to meet industrial requirements.

[0053] Among them, the housing 10 is provided with a back plate 13. The back plate 13 is located at the bottom of the housing 10. The back plate 13 is provided with a rib 131 and a first positioning groove 132. The rib 131 protrudes axially downward from the back of the back plate 13. The first positioning groove 132 is located in the middle of the rib 131. As Figure 5 shown, among them, a plurality of small holes are spacedly opened on the rib 131, facilitating the connection of the back plate 13 of the housing 10 and the cabinet with screws 125, enhancing the installation firmness, and at the same time facilitating the heat dissipation of the back plate 13 through the small holes, contributing to the heat dissipation of the rail module 1.

[0054] Among them, the chassis 24 is provided with a reinforcing rib 241 and a second positioning groove 242. The reinforcing rib 241 protrudes horizontally upward. The second positioning groove 242 is located in the middle of the reinforcing rib 241. The first positioning groove 132 and the second positioning groove 242 facilitate the positioning and installation of the screw 125 in the vertical direction. The reinforcing rib 241 helps to increase the local thickness of the chassis 24 and prevent the chassis 24 from being damaged during the tightening process of the screw cap and the screw. As Figure 9 shown.

[0055] Among them, an upper channel 225 is formed between the upper side wall 22 of the carrier 20 and the functional module 40, a lower channel 235 is formed between the lower side wall 23 of the carrier 20 and the functional module 40, and a bottom channel 236 is formed between the chassis 24 and the functional module 40. The upper channel 225, the lower channel 235, and the bottom channel 236 form the redundant space of the carrier 20. As Figure 10 shown, it is convenient for the wiring of the terminal 30 and the functional module 40, and at the same time convenient for forming a heat dissipation channel, contributing to the rapid heat dissipation between the carrier 20 and the housing 10, preventing the internal arrangement of the functional module 40 from being too dense and the heat from rising too fast, resulting in the thermal damage of the functional module 40 in the PDU.

[0056] Among them, the housing 10 is provided with a pair of inner chamfers 14 and mounting ears 15. One of the mounting ears 15 is arranged on the outside of the rail part 11, and the other mounting ear 15 is connected to the rear cover plate 26. As Figure 4As shown, the inner chamfer 14 is symmetrically located at the junction between the rail part 11 and the slide base 12, facilitating the carrier 20 to abut against the rail part 11. The thickness of the front cover plate 25 is suitable for covering the inner chamfer 14.

[0057] Among them, the side of the terminal 30 is retracted inward to increase the heat dissipation space. At the same time, the terminal 30 is located inside the carrier 20, which is convenient for improving the use safety of the terminal 30.

[0058] Among them, the channel 116 is selected to use PPO material, which is high-temperature resistant and insulating, and can withstand high temperatures of 110°C to 130°C. Among them, there is no solder joint between the copper sheet conductor 115 and the terminal 30, and at the same time, there is a high-temperature resistant and insulating channel 116, which can carry a larger power than traditional PDU, is high-temperature resistant, and is safer.

[0059] Among them, the rail module 1 can be customized in length, and the rail module 1 and the socket module 50 can be configured according to requirements. The socket module 50 can be plugged in, added or subtracted, and moved on the rail part 11. After rotation, the pin head 516 on the socket module 50 is in close contact with the copper sheet conductor 115 on the rail part 11 to connect the circuit; after reset rotation, the copper sheet on the socket module 50 is separated from the copper sheet conductor 115 on the rail part 11 to disconnect the circuit. In this way, the number of socket modules 50 of the PDU product can be increased or decreased at will, the variety of the socket module 50 of the PDU product can be replaced, the socket module 50 can be moved at will according to the on-site needs, which is more flexible and convenient. There is no need to prepare too many socket ports, and the socket position can be flexibly adjusted according to the computer position, making the wiring more beautiful. At the same time, the number of sockets can be elastically controlled to avoid unnecessary waste of resources and materials. The functional module 40 in the rail module 1 can be increased or decreased according to the specific required functions, which is more economical and reasonable, such as air switch module, lightning protection module, intelligent electric meter, double-break switch, single-P leakage protection module, double-USB module, current and voltage digital display meter, power indicator light, overload protection module and / or external wiring box 41, etc.

[0060] Among them, if the rail module 1, the socket module 50, and the functional module 40 fail individually, only the faulty module needs to be replaced, reducing the operation and maintenance cost, and there is no need to replace the entire PDU. Thus, through the better protection function and heat dissipation function of the carrier 20 for the functional module 40, the carrier 20 can be adapted to more standard intelligent device and sensor placement spaces, realizing flexible installation.

[0061] Since the quantities and sequences of multiple modules in traditional PDUs must be determined in advance, they need to be designed first and then customized. It is very difficult for customers to change the sequence after the products leave the factory. The track-type power distribution system of the present invention allows customers to arrange the quantities and positions of different socket modules 50 at will in the cabinet. Moreover, the functional modules in the carrier can also be customized for easy assembly. This greatly meets the customers' requirements for different quantities and sequences in various standard sockets of PDUs. At the same time, there are variables in the design and on-site situations that require timely adjustment. Even in the face of changes, the track-type power distribution system does not require secondary procurement. Similarly, the track-type power distribution system completely solves the problem of most mismatches of PDUs by customers' technical or procurement personnel, greatly eliminating the capital cost of secondary procurement after customers' mismatches, and at the same time eliminating the waste of time or project delays caused by secondary procurement.

[0062] As Figures 13 to 21 shown, the socket module 50 includes a body 51, a base 52, and a locking assembly 70. The body 51 is provided with a housing 60 and male pins 515. The male pins 515 are received in the housing 60 and the base 52. The housing 60 is provided with an annular groove 64. The base 52 is rotatably connected to the body 51. The base 52 is provided with a rotating base 521 and at least one locking portion 525 extending upward from the rotating base 521. The locking assembly 70 includes a locking member 71 and a switching member 73. The switching member 73 is slidably mounted on one side of the housing 60. The locking member 71 is annularly disposed between the locking portion 525 of the base 52 and the switching member 73. The locking portion 525 is rotatably connected to the annular groove 64 and extends toward the locking member 71. The locking member 71 is provided with at least a pair of locking grooves 712. The locking grooves 712 are spaced apart and opened on the lower side of the locking member 71. One of the locking grooves 712 is adjacent to the switching member 73. The locking portion 525 can selectively rotate between the locking grooves 712. This increases the selectivity of locking of the socket module 50 to meet different usage requirements. At the same time, the locking is safer and more stable, reducing the loss of the socket module 50.

[0063] Among them, the locking grooves 712 include a first locking groove 74 and a second locking groove 75. The first locking groove 74 is adjacent to the switching member 73. The second locking groove 75 is spaced apart from the first locking groove 74. The locking portion 525 can be selectively locked in the first locking groove 74 or the second locking groove 75 by the rotation of the rotating base 521. When the locking portion 525 abuts against the first locking groove 74, the socket module 50 can be locked or unlocked by adjusting the position of the switching member 73.

[0064] Among them, the main body 51 further includes a top cover 511, an inner cover 513 and a protection door 514. The male plug 515 is provided with three plug heads 516 and spring copper sheets 517. The top cover 511 and the inner cover 513 are provided with jacks. The protection door 514 is installed between the top cover 511 and the inner cover 513. The plug head 516 is connected to the spring copper sheet 517. The spring copper sheet 517 is installed between the rotating base 521 and the inner cover 513. The plug head 516 extends downward from the through hole 523 of the rotating base 521. When the main body 51 rotates relative to the base body 52, the male plug 515 contacts the copper sheet conductor 115 of the track, forming a powered-on state.

[0065] Among them, the base body 52 is further provided with a plug end 522. The plug end 522 is integrally connected to the rotating base 521. The plug end 522 is located below the rotating base 521. The side surface of the plug end 522 is adapted to accommodate the plug head 516. When in the normal state, the plug head 516 is accommodated in the plug end 522. When the main body 51 rotates relative to the base body 52, the plug head 516 contacts the copper sheet conductor 115 of the track, so that the male plug 515 forms a powered-on state.

[0066] The locking part 525 is provided with a locking head 526. The locking head 526 is located between the annular groove 64 and the locking member 71. The locking head 526 rotatably abuts against the locking member 71. The two sides of the locking head 526 are provided with a ramp surface 527 and an arc-shaped slope surface 528. The locking groove 712 is provided with an inclined groove surface 713 and / or an arc-shaped groove surface 714. The arc-shaped groove surface 714 of the first locking groove 74 is close to the switch member 73. The inclined groove surface 713 of the first locking groove 74 deviates from the switch member 73. When the locking head 526 turns into the locking groove 712, the ramp surface 527 of the locking member 71 contacts the inclined groove surface 713 of the locking groove 712, as Figure 19 shown.

[0067] Among them, the radian of the arc-shaped slope surface 528 and the arc-shaped groove surface 714 are similar, and the slope of the ramp surface 527 and the inclined groove surface 713 are similar.

[0068] Preferably, the slope α of the ramp surface 527 and the inclined groove surface 713 is 30° - 45°, as Figure 18 shown.

[0069] Further preferably, the slope angle α of the slope surface 527 and the inclined groove surface 713 is 33°. Among them, the slope surface 527 helps the locking head 526 to be selectively locked in the locking groove 712. Even when the switch member 73 is not pushed and the socket module 50 is in the unlocked state, a certain external force is required to rotate the body 51 so that the locking head 526 abuts against the inclined groove surface 713 of the locking groove 712, which plays a role of safety locking in real time. At the same time, when the locking head 526 rotates to the locking groove 712, the inclined groove surface 713 drops and contacts the slope surface 527, making a "click" or "clack" sound, which is convenient to prompt the user that the rotation is in place. Especially when the locking head 526 rotates into the first locking groove 74, the sound is more obvious. If both sides of the locking head 526 are arc slope surfaces 528 and both sides of the locking groove 712 are arc groove surfaces 714, both sides of the locking head 526 and the locking groove 712 are in arc surface contact. Whether the locking head 526 rotates clockwise or counterclockwise, the locking head 526 is too easy to abut against the locking member 71. On the contrary, if both sides of the locking head 526 and the locking groove 712 are connected by inclined surfaces, whether rotating clockwise or counterclockwise, the locking head 526 needs to exert force to abut against the locking member 71. Therefore, in order to increase the safety and installation convenience of the socket module 50, one side of the locking head 526 and the locking groove 712 is an arc surface docking structure, and the other side is an inclined surface docking structure. When installing, rotate the body 51, and the locking head 526 easily abuts against the arc groove surface 714 of the second locking groove 75, and the locking head 526 slides from the second groove to the first locking groove 74. When disassembling, rotate the body 51 in the reverse direction, and the locking head 526 needs to exert a little force to abut against the inclined groove surface 713 of the first locking groove 74, and the locking head 526 slides from the first locking groove 74 to the second locking groove 75. Among them, the slope angle α of the inclined groove surface 713 is adapted to the force for the locking head 526 to abut against the inclined groove surface 713 and the sound prompt for the rotation to be in place.

[0070] Among them, the locking portion 525 is provided with a protruding portion 529. The housing 60 is provided with an inner slide rail 641 and an outer slide rail 642. An annular groove 64 is formed between the inner slide rail 641 and the outer slide rail 642. The protruding portion 529 integrally extends outward from the lower end of the locking head 526. The inner end of the locking head 526 abuts against the inner slide rail 641, and the protruding portion 529 abuts against the outer slide rail 642, so that the locking head 526 can slide stably along the annular groove 64, as Figure 20 shown.

[0071] Among them, the seat body 52 is provided with a pair of locking parts 525, and the locking parts 525 are symmetrically located on the outer ring of the rotating base 521. The locking member 71 is provided with two pairs of locking grooves 712, and the locking grooves 712 are evenly spaced in the locking member 71, so that each locking part 525 can selectively rotate between two adjacent locking grooves 712. By symmetrically rotating the two locking parts 525, it is convenient to disperse the stress distribution on the locking member 71 and facilitate the sliding of the locking part 525 between the annular groove 64 and the locking member 71. Since both the locking part 525 and the locking groove 712 are symmetrically arranged, the other locking part 525 and the other pair of locking grooves 712 will not be separately described. The two locking parts 525 slide between the two corresponding locking grooves 712 respectively.

[0072] Among them, the locking member 71 is provided with a plurality of notches 715 and a plurality of reinforcing strips 716. The notches 715 are arranged between the reinforcing strips 716, and the reinforcing strips 716 are located above the locking grooves 712. The notches 715 help to increase the elasticity of the locking member 71, and the reinforcing strips 716 are beneficial to increasing the strength of the locking member 71, especially the strength at the locking grooves 712, to prevent the locking member 71 from being damaged or broken due to the limited load that the locking member 71 can withstand during the process of the locking head 526 pushing open the locking member 71, as Figure 17 shown.

[0073] The switch member 73 includes a baffle 731, a sliding member 732 and a joint portion 733. One side of the housing 60 is provided with a switch portion 65. The sliding member 732 is slidably joined to the switch portion 65 through the joint portion 733. The baffle 731 extends inward integrally from the sliding member 732, and the baffle 731 is slidably pressed against the reinforcing strip 716 above the first locking groove 74. Among them, when the socket module 50 is in the unlocked state or the preliminary locking state, the baffle 731 deviates from the first locking groove 74. When the socket module 50 is in the fully locked state, the baffle 731 slides above the first locking groove 74, and the baffle 731 is pressed against the reinforcing strip 716 above the first locking groove 74. The pressure of the baffle 731 makes the locking head 526 unable to push open the inclined pressure surface. In the unlocked state, as the baffle 731 slides to the side, the pressure above the first locking groove 74 is released, and the locking head 526 can push open the inclined pressure surface.

[0074] Furthermore, if along the rotation direction of the locking head 526 from the first locking groove 74 to the second locking groove 75, the arc groove surface 714 of the first locking groove 74 is close to the baffle 731, and the inclined groove surface 713 of the first locking groove 74 is far from the baffle 731. The other locking grooves 712 are provided with inclined groove surfaces 713 and arc groove surfaces 714 in the same direction as the first locking groove 74, or only inclined groove surfaces 713 are provided.

[0075] Among them, the locking assembly 70 further includes a plurality of elastic members 72. The locking member 71 is provided with a plurality of connecting lugs 711, and the housing 60 is provided with a plurality of connecting posts 63. The connecting lugs 711 extend radially outward from the locking member 71. The connecting lugs 711 and the elastic members 72 are sleeved on the connecting posts 63. Each elastic member 72 is located above the connecting lug 711, enabling the locking member 71 to be elastically connected to the housing 60, so that the locking portion 525 elastically abuts against the locking member 71. This not only helps to increase the locking firmness of the locking head 526 in the locking groove 712, but also helps to improve the reset efficiency of the locking member 71 after being pushed open by the locking head 526, and increases the prompting sound.

[0076] Among them, the base body 52 is further provided with a positioning portion 520. The positioning portion 520 protrudes horizontally downward from the rotating base 521. The positioning portion 520 is adapted to the limiting groove 114 of the track portion 11, which is convenient for quickly identifying the correct installation direction of the socket module 50, avoiding the wrong installation of the socket module 50, and making the rotary installation of the socket module 50 faster and more reliable, as Figure 16 shown.

[0077] Among them, the second locking groove 75 may also only have an inclined groove surface 713 and no arc groove surface 714. Thus, the first locking groove 74 and the second locking groove 75 may have the same structure or different structures.

[0078] During installation, insert the socket module 50 into the sliding groove 111 of the track portion 11. The positioning portion 520 corresponds to the limiting groove 114 of the track portion 11, and the locking head 526 is located in the second locking groove 75, as Figure 21 shown. Rotate the housing 60 of the rotating body 51. The locking portion 525 pushes open the arc groove surface 714 of the second locking groove 75, and the locking member 71 is elastically pushed upward. The locking portion 525 moves from the second locking groove 75 to the first locking groove 74 along the annular groove 64. When the locking head 526 slides into the first locking groove 74, the locking member 71 falls back, and the inclined groove surface 713 touches the ramp surface 527 of the locking head 526, generating a prompting sound, indicating preliminary locking, as Figure 13 shown. The user can choose to strengthen the locking by operating the switch member 73, or can choose not to slide the switch member 73 and maintain the preliminary locking state to meet different usage requirements.

[0079] When fully locked, the locking portion 525 is located in the first locking groove 74. Slide the switch member 73, slide the baffle 731 of the switch member 73 from the side of the first locking groove 74 to above it, and press the partial reinforcing strip 716 above the first locking groove 74, such as pressing the reinforcing strip 716 above the arc groove surface 714, so that the locking head 526 cannot push open the inclined groove surface 713 of the first locking groove 74, and the socket module 50 is in a fully locked state.

[0080] When unlocking, slide the switch member 73 to the other side. The baffle 731 of the switch member 73 moves away from above the first locking groove 74, relieving the pressure above it, enabling the locking head 526 to push open the inclined groove surface 713 of the first locking groove 74, facilitating the movement towards the second locking groove 75.
