Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical connector technology, specifically to an anti-loosening power distribution connector. Background Technology
[0002] Power distribution connectors are primarily used for distributing and controlling electrical energy, distributing a single power source to multiple branch circuits to power different devices or areas. Power distribution connectors consist of plugs and sockets. Taking a distribution cabinet with one input and two outputs as an example, one set of input sockets and two sets of output sockets are correspondingly installed on the outer wall of the cabinet. The cabinet contains one main busbar and two branch busbars. The input sockets connect to the main busbar, which in turn connects to the two branch busbars. The two branch busbars connect to the two sets of output sockets. The plug connects to an external power supply unit. After the plug is inserted into the input socket, the two sets of output sockets can supply power to the outside, such as supplying power to two sets of output cables, achieving the effect of one input and two outputs. Therefore, the connection strength between the plug and the input socket directly affects the power supply stability of the distribution cabinet, and anti-loosening structures are usually required for the plug and socket.
[0003] An existing patent discloses a power connector with an anti-loosening function (CN214957619U). As the threaded rod enters the cavity, the spring contracts. Simultaneously, the irregularly shaped sliding plate slides, pushing the trapezoidal sliding plate inside the cavity out of the socket. Under the action of the toothed groove on the side wall of the connecting plate, the arc-shaped toothed plate rotates, causing the fixing rod to rotate with the arc-shaped toothed plate. This results in the fixing rod being tightly fitted into the groove on the side wall of the U-shaped plug, preventing the U-shaped plug from loosening. This patent improves the connection strength between the U-shaped plug and the socket through the cooperation of the fixing rod and the groove on the side wall of the U-shaped plug. However, when the U-shaped plug is subjected to external vibration or accidental contact, it may experience axial and radial forces. While this patent effectively limits axial forces, its effectiveness in limiting radial forces is poor, making it more prone to damaging the gear transmission structure. Furthermore, loosening of the connector increases resistance, affecting power transmission and potentially causing a fire, posing a safety hazard.
[0004] Therefore, there is an urgent need for a non-loosening power distribution connector to ensure the stability of the plug and socket connection. Utility Model Content

[0032] (III) Beneficial Effects
[0033] The beneficial effects of this utility model are:
[0034] During the insertion process, the elastic retaining plate contacts and presses against the hook-shaped plate. The elastic retaining plate is pressed vertically towards the plug until it separates from the hook-shaped plate. The elastic retaining plate extends vertically out of the plug under its own elastic force. Finally, the elastic retaining plate is engaged with the hook-shaped plate.

[0035] In the plugged-in state, both the unlocker and the pair of elastic plates are in an expanded state. The unlocker enhances the elasticity of the elastic plates, thereby further strengthening the connection between the socket and the plug, making it difficult for the elastic plates to detach laterally from the hook plate. In the unlocked state, the unlocker causes the pair of elastic plates to retract, making the elastic plates contact and engage with the hook plate. Then, moving the plug laterally separates the socket and the plug, making unlocking very convenient. Attached Figure Description

[0050] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0051] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0052] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0053] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; "connection" can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0054] See Figures 1 to 4 This utility model provides an anti-loosening power distribution connector, which includes a socket 1, a plug 2, a pair of hook-shaped plates 3, a pair of elastic retaining plates 4, and a pair of unlockers 5. The socket 1 is inserted into the plug 2, and the end of the socket 1 facing the plug 2 is located inside the plug 2. Hook-shaped plates 3 are correspondingly provided at the top and bottom of the socket 1. Elastic retaining plates 4 are correspondingly provided at the top and bottom of the plug 2. The elastic retaining plates 4 can move vertically to engage with the hook-shaped plates 3. Unlockers 5 are fixedly provided on both side walls of the plug 2, and the two free ends of the unlockers 5 are correspondingly connected to the pair of elastic retaining plates 4. The unlockers 5 can extend and retract vertically. Vertically refers to the extension and retraction direction of the unlockers 5, horizontally refers to the insertion direction of the socket 1 and the plug 2, and longitudinally refers to the length direction of the hook-shaped plates 3.
[0055] In this embodiment, socket 1 is installed on the power distribution cabinet. Socket 1 has a built-in first mating block 11, on which multiple pins 111 are provided. The multiple pins 111 are connected to the internal circuit of the power distribution cabinet through a first cable or copper busbar. Plug 2 is a power vehicle plug. Plug 2 has a built-in second mating block 23, on which multiple sockets 231 are provided. The multiple sockets 231 are connected to the internal circuit of the power vehicle through a second cable. When socket 1 and plug 2 are plugged in (plugged-in state), the end face of the first mating block 11 abuts against the end face of the second mating block 23, and simultaneously the multiple pins 111 are inserted into the corresponding sockets 231, realizing the circuit connection between the power distribution cabinet and the power vehicle.
[0056] The hook-shaped plate 3 has a hook at one end facing the elastic locking plate 4. In the plugged-in state, since the socket 1 is partially embedded inside the plug 2, the elastic locking plate 4 can move to the hook. During the plugging process, the elastic locking plate 4 contacts and is pressed against the hook-shaped plate 3. The elastic locking plate 4 is pressed vertically towards the plug 2 until the elastic locking plate 4 separates from the hook-shaped plate 3. The elastic locking plate 4 extends vertically out of the plug 2 under its own elastic force. Finally, the elastic locking plate 4 is locked into the hook-shaped plate 3. The hook-shaped plate 3 limits the elastic locking plate 4, i.e., the plug 2, both horizontally and vertically, thereby enhancing the connection strength between the socket 1 and the plug 2.
[0057] The multiple sockets 231 and multiple pins 111 themselves have a certain vertical limiting capability. By engaging the elastic retaining plate 4 with the hook-shaped plate 3, the vertical connection strength between the socket 1 and the plug 2 is further enhanced, which can basically meet the vertical limiting requirements. Optionally, to further enhance the vertical limiting strength, the outer wall of the socket 1 can partially abut against the inner wall of the plug 2, or the wall of the socket 1 can be partially embedded into the wall of the plug 2.
[0058] The two free ends of the unlocker 5 are connected to a pair of elastic locking plates 4. In the plugged state, both the unlocker 5 and the pair of elastic locking plates 4 are in an expanded state. The unlocker 5 enhances the elasticity of the elastic locking plates 4, thereby further strengthening the connection between the socket 1 and the plug 2, making it difficult for the elastic locking plates 4 to come off the hook plate 3 laterally. In the unlocked state, the unlocker 5 causes the pair of elastic locking plates 4 to retract, so that the elastic locking plates 4 contact and engage with the hook plate 3. Then, moving the plug 2 laterally separates the socket 1 and the plug 2, making unlocking very convenient.
[0059] The unlocker 5 is fixedly mounted on the side wall of the plug 2, and its free end is connected to the elastic locking plate 4. The unlocker 5 can limit the longitudinal movement of the elastic locking plate 4, effectively preventing the elastic locking plate 4 from disengaging from the hook-shaped plate 3 longitudinally. Furthermore, the pair of unlockers 5 and the pair of elastic locking plates 4 form a square frame structure, which can bear force as a whole, effectively ensuring the connection strength after the socket 1 and plug 2 are plugged in, thereby ensuring power transmission efficiency and reducing safety hazards.
[0060] like Figure 5 As shown, the hook-shaped plate 3 includes a vertical plate 31, a horizontal plate 32, and a baffle 33. The two ends of the horizontal plate 32 are perpendicularly arranged to the vertical plate 31 and the baffle 33. The vertical plate 31 is perpendicularly arranged on the top or bottom surface of the socket 1. The vertical plate 31, the horizontal plate 32, and the baffle 33 form a slot 34, and the elastic plate 4 can engage with the slot 34. Specifically, the shape and size of the slot 34 are adapted to the shape and size of the elastic plate 4. An opening is formed between the bottom end of the baffle 33 and the top surface of the socket 1, through which the elastic plate 4 enters the slot 34. During insertion, the baffle 33 presses against the elastic plate 4, causing the elastic plate 4 to contract inwards towards the plug 2. The elastic plate 4 can then enter the slot 34 through the opening. As the baffle 33 disengages from the elastic plate 4, the elastic plate 4 resets due to its own elasticity, expanding outwards towards the plug 2 until the elastic plate 4 and the slot 34 are fully engaged. The engagement process between the elastic plate 4 and the slot 34 is automatically completed during the insertion process, that is, during the lateral movement of the plug 2, making operation convenient.
[0061] See Figure 6 and Figure 7 The bottom surface of the baffle 33 is configured as a first inclined surface 331; the head end of the elastic plate 4 is configured with a second inclined surface 41; when the plug 2 is moved laterally, the first inclined surface 331 and the second inclined surface 41 are in face-to-face contact, and the elastic plate 4 can spring back into the slot 34 after being pressed. Specifically, the first inclined surface 331 and the second inclined surface 41 have a guiding function, so that the elastic plate 4 can slide into the slot 34 more smoothly. In addition, the height of the end of the first inclined surface 331 away from the slot 34 should be higher than the height of the end of the first inclined surface 331 facing the slot 34, and the second inclined surface 41 is correspondingly configured so that after the elastic plate 4 is engaged with the slot 34, the baffle 33 has sufficient vertical dimension to limit the elastic plate 4, effectively preventing the elastic plate 4 from being dislodged from the slot 34 by external force.
[0062] In one embodiment, the elastic locking plate 4 includes a T-shaped locking plate 42 and a first spring 43; the top and bottom ends of the plug 2 are provided with T-shaped mounting grooves 21, and the two ends of the T-shaped mounting grooves 21 are connected to the two side walls of the plug 2 respectively; the tail end of the T-shaped locking plate 42 is slidably connected to the T-shaped mounting groove 21 vertically; the two free ends of the T-shaped locking plate 42 are connected to a pair of unlockers 5 respectively; the first spring 43 is built into the T-shaped mounting groove 21; one end of the first spring 43 is connected to the T-shaped mounting groove 21, and the other end is connected to the T-shaped locking plate 42. Specifically, the T-shaped locking plate 42 cooperates with the T-shaped mounting groove 21, which on the one hand can prevent the T-shaped locking plate 42 from detaching from the T-shaped mounting groove 21 vertically, and on the other hand, the two are slidably connected longitudinally, so that the T-shaped locking plate 42 can be moved out of the T-shaped mounting groove 21 longitudinally, and the first spring 43 is fixedly set on the T-shaped mounting groove 21, which facilitates the maintenance and replacement of the T-shaped locking plate 42. The first spring 43 is used to lift the T-shaped card plate 42, so that the T-shaped card plate 42 can be inserted into the card slot 34.
[0063] In another embodiment, the elastic plate 4 further includes uprights 44 and a base plate 45 built into the T-shaped mounting groove 21; multiple uprights 44 are vertically arranged on the base plate 45; multiple countersunk holes 421 are opened on the tail end of the T-shaped plate 42, and the multiple uprights 44 and the multiple countersunk holes 421 are slidably connected vertically; a first spring 43 is sleeved on the uprights 44; the two ends of the first spring 43 are connected to the base plate 45 and the T-shaped plate 42 respectively; along the length direction of the T-shaped mounting groove 21, the base plate 45 and the T-shaped plate 42 are slidably connected to the T-shaped mounting groove 21. In this embodiment, the multiple uprights 44 are fixedly arranged on the base plate 45, and the uprights 44 and the countersunk holes 421 are slidably connected vertically, so that the elastic plate 4 can be moved out of the T-shaped mounting groove 21 as a whole, which facilitates the overall disassembly and assembly, as well as the maintenance and replacement of each component.
[0064] like Figure 8As shown, the unlocking device 5 includes a double-headed telescopic rod 51, a bolt 52, and a pair of sliders 53; a groove 22 is provided on the side wall of the plug 2; the sliders 53 are slidably connected to the groove 22 in a vertical direction; the double-headed telescopic rod 51 is fixedly installed on the side wall of the plug 2; both ends of the double-headed telescopic rod 51 are connected to the pair of sliders 53 respectively; the free end of the elastic locking plate 4 is connected to the free end of the slider 53 by the bolt 52. Specifically, the two ends of the double-headed telescopic rod 51 can extend and retract independently, thereby driving the pair of elastic locking plates 4 to contract or expand. The bolt 52 detachably connects the sliders 53 and the elastic locking plates 4, facilitating their assembly and disassembly, and at the same time connects the pair of unlocking devices 5 and the pair of elastic locking plates 4 into a square frame structure, effectively enhancing the lateral limiting strength of the square frame structure. The slider 53 and the slide groove 22 are slidably connected in the vertical direction, so that the plug 2 can limit the slider 53 in the longitudinal and lateral directions. The double-headed telescopic rod 51 is fixedly set on the side wall of the plug 2, which further enhances the longitudinal and lateral limiting ability of the plug 2 to the unlocker 5, and can effectively improve the connection strength between the socket 1 and the plug 2.
[0065] Furthermore, the double-headed telescopic rod 51 includes a sleeve 511, a second spring 512, and a pair of push rods 513; the sleeve 511 is embedded in the sliding groove 22; the pair of push rods 513 are mirror images of the two ends of the sleeve 511 and are vertically slidably connected to the sleeve 511; the second spring 512 is built into the sleeve 511; the two ends of the second spring 512 are connected to the pair of push rods 513. Specifically, the sleeve 511 is embedded in the sliding groove 22, which simplifies the connection structure between the sleeve 511 and the side wall of the plug 2 and improves the longitudinal and lateral limiting ability of the plug 2 on the sleeve 511. The push rod 513 is a T-shaped push rod, and the end of the sleeve 511 cooperates with the T-shaped push rod to prevent the push rod 513 from coming out of the sleeve 511. The end of the sleeve 511 can limit the maximum extension distance of the push rod 513, and the second spring 512 supports between the pair of push rods 513. Manually moving a pair of push rods 513 to retract will simultaneously cause a pair of elastic locking plates 4 to retract, thus unlocking the device. The end of the sleeve 511 can be abutted by the slider 53 to limit the maximum retraction distance of the push rods 513.
[0066] Secondly, a handle 54 is provided on the side of the slider 53 facing away from the plug 2. In this embodiment, the handle 54 is an extension of the slider 53 and is L-shaped. When unlocking, the operator's thumb and forefinger press the pair of handles 54 vertically to retract the handles 54 until they abut against the sleeve 511; the operator's thumb and forefinger then come together to pull out the plug 2 horizontally, thus separating the plug 2 from the socket 1. After the operator's fingers are removed from the handles 54, the second spring 512 automatically resets, and the pair of elastic locking plates 4 reset. The next time the plug 2 is inserted into the socket 1, the elastic locking plates 4 can automatically engage in the groove 34 during the horizontal movement, making operation convenient.
[0067] It should be understood that the above description of the specific embodiments of this utility model is only for illustrating the technical route and features of this utility model, and its purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. However, this utility model is not limited to the specific embodiments described above.
