Description

Technical Field

[0001] This utility model relates to the field of quick connector technology, and in particular to a quick connector, wire and socket assembly. Background Technology

[0002] In diverse scenarios such as video shooting, film and television production, and photography, the connectivity needs of various devices are becoming increasingly complex and varied. Among these, the connection between equipment such as set lights and control boxes places specific demands on the cables. For example, waterproof, high-current cables that can be quickly spliced ​​and extended are required to meet the needs of stable power supply and ease of operation in complex environments, while ensuring safety and reliability during use.

[0003] Currently, existing waterproof high-current cables typically employ a structure consisting of a male plug, a male plug sleeve, a female plug, and a female plug sleeve. The male plug sleeve fits over the male plug, and the female plug sleeve fits over the female plug; the plug and sleeve can only rotate, not move axially. When the male plug is inserted into the female socket of a device, the threaded groove inside the male plug sleeve locks in place with the protrusions on the surface of the female socket, preventing the connector from accidentally disengaging. The connection between the female plug and the male socket is handled similarly. While this connection method ensures stability to a certain extent, it presents significant problems in practical applications.

[0004] When the shooting scene changes and the existing cable length is insufficient, cable extension is required. However, due to the presence of locking sleeves, both the male and female plugs are located within their respective sleeves, preventing direct connection. Existing cable extension methods have several limitations. One approach is to install a drop cable at the equipment end, which acts as an adapter. However, this increases the complexity of the equipment and the uncontrollability of the connection. Furthermore, the quality and stability of the drop cable are difficult to guarantee, potentially affecting the reliability of the entire connection system. Another approach is to use custom-made extension cables to meet the extension needs. This not only increases costs but also takes a long time to customize, making it impossible to meet the needs of rapid scene changes on-site and limiting the flexibility and efficiency of shooting operations. Utility Model Content

[0005] The purpose of this invention is to overcome the problem of excessive restrictions on wire expansion in the prior art.

[0006] To achieve the above objectives, this utility model discloses a quick connector, comprising: a plug-in component including a plug and a housing; a locking sleeve fitted onto the housing, the locking sleeve being axially slidable relative to the housing and circumferentially rotatable relative to the housing; and an elastic element disposed between the locking sleeve and the housing. When the locking sleeve is pressed axially, the locking sleeve compresses the elastic element and slides away from the plug, causing the plug to extend from the locking sleeve. When the pressing is released, the elastic element pushes the locking sleeve back to its original position, causing the locking sleeve to cover the plug.

[0007] By adopting the above solution, when cable expansion is needed, the locking sleeve can be moved back to expose the plug, thus enabling rapid expansion of multiple cables. At the same time, this design does not affect the locking effect between the locking sleeve and the device, ensuring the stability and security of the connection. It greatly improves the flexibility and convenience of cable connections, meets the needs of rapid cable expansion in different scenarios, and reduces costs and time consumption during shooting and production, demonstrating significant practical application value.

[0008] Furthermore, a first locking mechanism is provided on the outer surface of the housing, and a second locking mechanism is provided on the inner surface of the lock sleeve. When the lock sleeve is rotated to the locking angle, the first locking mechanism and the second locking mechanism cooperate with each other to restrict the elastic element from resetting.

[0009] By adopting the above solution, in scenarios requiring continuous and stable power supply or signal transmission, such as long-term data acquisition equipment connections, the quick-connect coupling avoids the problem of the locking sleeve moving and the coupling accidentally disconnecting when subjected to external pulling or slight impact, thus ensuring the stability and reliability of the connection. It also enhances the quick-connect coupling's anti-interference capability in complex environments, ensuring that the cable connection remains stable under harsh conditions and will not easily disconnect due to external factors, guaranteeing the normal operation of the equipment.

[0010] Furthermore, the first locking mechanism includes at least two protrusions spaced apart circumferentially along the housing; the second locking mechanism includes a plurality of locking grooves corresponding to the protrusions arranged circumferentially along the locking sleeve.

[0011] By adopting the above scheme, a multi-point locking structure is formed, which can distribute external forces more evenly, so that the quick connector can maintain a stable connection when subjected to external forces such as pulling and twisting in all directions, effectively preventing the plug from accidentally coming off the socket and greatly improving the reliability of the connection.

[0012] Furthermore, the locking groove includes a first sliding groove and a second sliding groove that are vertically connected, the first sliding groove being arranged along the axial direction of the lock sleeve, and the second sliding groove being arranged along the circumferential direction of the lock sleeve.

[0013] By adopting the above scheme, the first slide groove is arranged along the axial direction of the locking sleeve, providing clear axial guidance for the protrusion on the housing. When the protrusion enters the first slide groove, the locking ring is rotated to allow the protrusion to enter the second slide groove arranged circumferentially, thereby achieving locking. This increases the difficulty of accidental unlocking.

[0014] Furthermore, the ratio of the number of protrusions to the number of locking grooves is 1:N, where N≥1.

[0015] By adopting the above solution and increasing the number of locking slots, the success rate of insertion and alignment can be increased, avoiding the need for excessive rotation for alignment; at the same time, the locking ring can be adapted to housings with more protrusions.

[0016] Furthermore, a first abutting portion is provided on the inner surface of the lock sleeve near the plug, a first annular retaining ring is provided on the inner surface of the lock sleeve away from the plug, a second annular retaining ring is provided on the outer surface of the housing, the side of the second annular retaining ring facing the plug is the second abutting portion, the second annular retaining ring is located between the first abutting portion and the first annular retaining ring, one end of the elastic member abuts against the first abutting portion, and the other end abuts against the second abutting portion.

[0017] By adopting the above scheme, the first abutment part and the second abutment part provide a clear and definite installation position for the elastic element.

[0018] Furthermore, the lock sleeve is provided with a rotating groove, and the end of the rotating groove is provided with a locking hole.

[0019] By adopting the above solution, the locking and unlocking operations between the lock sleeve and the equipment can be accurately performed, avoiding operational errors caused by blind rotation and improving the accuracy and efficiency of operation.

[0020] A cable includes a male connector unit, a female connector unit, and a cable body connecting the two, wherein the male connector unit and / or the female connector unit are quick connectors.

[0021] By adopting the above solution, a sliding locking sleeve can be installed in either the male or female plug unit to achieve the desired plug-in effect, making plugging more convenient. With sliding locking sleeves on both, there's no need to identify and search for the sliding sleeve during use; simply pick up either end to operate, improving wiring efficiency.

[0022] Furthermore, when both the male and female connectors are quick-connectors, the locking sleeve of one of the male and female connectors can be rotated and locked to the plug of the other.

[0023] By adopting the above solution, it is ensured that the lock sleeve can cover the connection point and prevent it from being damaged by bumps.

[0024] A socket assembly includes a male socket, a female socket, and at least one wire. When there is only one wire, the male socket is plugged into the female plug unit, and the female socket is plugged into the male plug unit. When there are two or more wires, the male plug units and female plug units of the two or more wires are sequentially and linearly interleaved, with the female plug unit at one end of the linear connection plugged into the male socket, and the male plug unit at the other end of the linear connection plugged into the female socket.

[0025] By adopting the above solution, the connection method, whether using a single cable or multiple cables, can be flexibly adjusted according to the actual usage scenario. In small areas, a single cable connecting the male and female sockets may be sufficient to meet the power supply needs of simple devices. However, in large data centers or outdoor shooting locations, where the space is large and the equipment is complexly distributed, using multiple cables connected in a linear, interlaced manner allows for free adjustment of the cable routing based on the specific location of the equipment, easily bypassing obstacles and enabling the socket assembly to adapt to various complex spatial layouts.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] 1. By fitting a locking sleeve onto the housing and allowing it to slide axially, in conjunction with an elastic element, the locking sleeve moves to expose the plug when the elastic element is compressed. This enables convenient and rapid expansion of multiple wires, greatly improving the efficiency of wire connection. For example, on a film set, when rapid scene changes require extending the wires, staff can quickly operate the quick connector to complete the expansion, avoiding delays in filming due to wire issues.

[0028] 2. Despite enabling rapid expansion, the quick-connect design does not sacrifice the locking function of the locking sleeve itself and the device. During normal use, the elastic element is in its initial state, the locking sleeve is located at one end of the connector, and the plug is located inside the locking sleeve. At this time, after the connector is connected to the device, the locking sleeve can lock with the device in the same way as in the traditional way, preventing the connector from accidentally disengaging from the socket and ensuring the stability and safety of the connection.

[0029] 3. The quick-connect coupling has a simple structure and is easy to operate. Operators only need to compress the elastic element to move the locking sleeve, thus exposing the plug for expansion operations. No complicated tools or cumbersome steps are required, making operation simple and convenient, reducing the technical requirements for operators, and even ordinary workers can easily learn to use it.

[0030] 4. Because the male and / or female connectors in the cable function as quick connectors, the cable can adapt to a wider range of application scenarios with varying length requirements. Whether it's small-scale indoor shooting or large-scale outdoor film and television production, cable expansion can be done quickly and flexibly according to actual needs, eliminating the need to prepare large quantities of custom cables of different lengths in advance, thus reducing costs and inventory pressure.

[0049] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0050] Please refer to Embodiment 1 of this utility model. Figures 1 to 6 A quick connector is provided, including a plug 1, a locking sleeve 2, and an elastic element 3. The plug 1 includes a plug 11 and a housing 12, wherein the plug 11 is not limited to being male or female. The plug 11 is fixedly connected to the housing 12, and the fixed connection method is not limited to welding, threaded connection, snap-fit, or integral connection. The locking sleeve 2 is sleeved on the housing 12. The locking sleeve 2 can slide axially relative to the housing 12 and can rotate circumferentially relative to the housing 12. The elastic element 3 is disposed between the locking sleeve 2 and the housing 12. When the locking sleeve 2 is pressed axially, the locking sleeve 2 compresses the elastic element 3 and slides away from the plug 11, causing the plug 11 to extend out of the locking sleeve 2. The extension length of the locking sleeve 2 must meet the insertion depth. When the pressing is released, the elastic element 3 pushes the locking sleeve 2 back to its original position, so that the locking sleeve 2 covers the plug 11. At the same time, the locking sleeve 2 is provided with a rotating groove 22, and the end of the rotating groove 22 is provided with a locking hole 23. Under normal conditions, the plug 11 with this structure can be directly connected to the male socket 40 or the female socket 50. Simultaneously, the rotating groove 22 on the locking sleeve 2 is aligned with the protrusion 111 on the outer surface of the male socket 40 or the female socket 50 and rotated. When the protrusion 111 aligns with the locking hole 23, a locking effect is achieved, thus protecting the plug 11 from damage by impact. When the cable length needs to be increased, the locking sleeve 2 is unlocked from the male socket 40 or the female socket 50, and the plug 11 is pulled out. Then, the locking sleeve 2 is slid towards the other end of the connector 1, i.e., the end away from the plug 11, thereby compressing the elastic element 3 and exposing the plug 11. At this point, the exposed plug 11 can be directly connected to a plug 11 of the same type of cable, requiring a male-female match, thus achieving rapid cable expansion and wiring.

[0051] In this embodiment 1, by moving the locking sleeve 2 back to expose the plug 11, multiple wires can be quickly connected. Simultaneously, this design does not affect the locking effect of the locking sleeve 2 on the device, ensuring the stability and security of the connection. This significantly improves the flexibility and convenience of wire connections, meeting the needs for rapid wire expansion in different scenarios, reducing costs and time consumption during shooting and production, and has significant practical application value. It should be noted that the elastic element 3 includes, but is not limited to, a spring.

[0052] To further improve the stability of the plug 11 during cable expansion, it is necessary to temporarily fix the locking sleeve 2, which is affected by the spring return. Therefore, in some embodiments, a first locking mechanism 4 is provided on the outer surface of the housing 12, and a second locking mechanism 5 is provided on the inner surface of the locking sleeve 2. When the locking sleeve 2 rotates to the locking angle, the first locking mechanism 4 and the second locking mechanism 5 cooperate to restrict the return of the elastic element 3. This design prevents the locking sleeve 2 from moving due to the automatic return of the elastic element 3, thus avoiding accidental disconnection of the connector when the quick connector is subjected to external pulling or slight impact, especially in scenarios requiring continuous and stable power supply or signal transmission, such as long-term data acquisition equipment connections. This ensures the stability and reliability of the connection. It also enhances the quick connector's anti-interference capability in complex environments, ensuring that the cable connection remains stable under harsh conditions and will not easily disconnect due to external factors, thus guaranteeing the normal operation of the equipment.

[0053] In some embodiments, the first locking mechanism 4 and the second locking mechanism 5 each have an outwardly protruding sliding portion and a recessed sliding groove portion within the housing, providing sliding guidance for the sliding portion and achieving a locking effect. In this embodiment 1, the first locking mechanism 4 includes at least two protrusions 41 spaced apart circumferentially along the housing 12, and the second locking mechanism 5 includes a plurality of locking grooves 52 corresponding to the protrusions 41, arranged circumferentially along the locking sleeve 2. This forms a multi-point locking structure, which can more evenly distribute external forces, allowing the quick connector to maintain a stable connection state when subjected to pulling, twisting, or other external forces from various directions, effectively preventing the plug 11 from accidentally disengaging from the socket and greatly improving the reliability of the connection. It should be noted that the specific structures of the first locking mechanism 4 and the second locking mechanism 5 described above can be interchanged or replaced with others, and this embodiment 1 does not impose specific limitations.

[0054] In this embodiment 1, the locking groove 52 includes a first sliding groove 521 and a second sliding groove 522 connected vertically. The first sliding groove 521 is arranged along the axial direction of the locking sleeve 2, and the second sliding groove 522 is arranged along the circumferential direction of the locking sleeve 2. The first sliding groove 521, arranged along the axial direction of the locking sleeve 2, provides clear axial guidance for the protrusion 41 on the housing 12. When the protrusion 41 enters the first sliding groove 521, by rotating the locking ring, the protrusion 41 enters the second sliding groove 522 arranged along the circumferential direction, thereby achieving a locking angle and locking, increasing the difficulty of accidental unlocking. In other embodiments, the locking groove 52 can also be configured as a threaded groove structure, or other rotatable locking structures. This embodiment does not make specific limitations, as long as locking can be achieved.

[0055] In other embodiments, the number of protrusions 41 can be multiple, and the number of locking grooves 52 can also be multiple. Specifically, the following condition can be met: the ratio of the number of protrusions 41 to the number of locking grooves 52 is 1:N, where N≥1. This ensures that the number of locking grooves 52 is always more than twice the number of protrusions 41, and the user can set it reasonably according to the actual situation. By increasing the number of locking grooves 52, the probability of successful insertion and alignment can be increased, avoiding the need for excessive rotation for alignment; at the same time, it allows the locking ring to adapt to the housing 12 with more protrusions 41. Preferably, the protrusions 41 are evenly spaced along the circumference of the housing 12, which can improve the alignment effect with the locking grooves 52.

[0056] Since the locking sleeve 2 needs to align the protrusion 41 with the locking groove 52 during the sliding process along the housing 12 before the protrusion 41 can smoothly slide into the locking groove 52, in order to facilitate accurate alignment during sliding, in some embodiments, an axial marking line can be set on the outside of the locking sleeve 2, and an axial marking line can also be set on the housing 12. When the two marking lines coincide, it means that the protrusion 41 is aligned with the locking groove 52 and can slide in smoothly, avoiding the problem of difficulty in locking.

[0057] Since the sliding relationship between the connector 1 and the locking sleeve 2 is not unlimited, the limiting relationship in this embodiment 1 is described in detail here. A first abutting portion 21 is provided on the inner surface of the locking sleeve 2 near the plug 11. The first abutting portion 21 is an annular stepped structure formed inside the locking sleeve 2. A first annular retaining ring 51 is provided on the inner surface of the locking sleeve 2 away from the plug 11. Optionally, the locking groove 52 can be provided on the end of the first annular retaining ring 51 away from the plug 11. A second annular retaining ring 6 is provided on the outer surface of the housing 12. The side of the second annular retaining ring 6 facing the plug 11 is the second abutting portion 61. The second annular retaining ring 6 is located between the first abutting portion 21 and the first annular retaining ring 51. One end of the elastic member 3 abuts against the first abutting portion 21, and the other end abuts against the second abutting portion 61. The connection between the first annular retaining ring 51 and the locking sleeve 2 includes, but is not limited to, screw connection, fixed connection, or snap-fit, as long as it ensures that both rotate synchronously. The first annular retaining ring 51 protrudes slightly towards the axis of the locking sleeve 2. The depth of the stepped structure protruding towards the axis of the locking sleeve 2 is consistent with the depth of the first annular retaining ring 51 protruding axially, thus creating a sliding space between them. The second annular retaining ring 6 of the housing 12 slides within this sliding space, and the height of the second annular retaining ring 6 protruding from the surface of the housing 12 is consistent with the depth of the locking ring protruding axially, so that the first abutting part 21 and the locking ring can limit the maximum position of the locking sleeve 2 sliding axially along the surface of the housing 12. Preferably, the second annular retaining ring 6 is integrally formed with the housing 12. At the same time, one end of the elastic member 3 abuts against the first abutting part 21, and the other end abuts against the second abutting part 61. The first abutting part 21 and the second abutting part 61 provide a clear and definite installation position for the elastic member 3.

[0058] Optionally, a sealing element 7 and / or a gasket 8 are provided between the second annular retaining ring 6 and the locking ring. When both the sealing element 7 and the gasket 8 are present, the gasket 8 is positioned between the sealing element 7 and the locking ring. The sealing element 7 effectively prevents external substances such as dust, moisture, and humidity from entering the quick connector, thereby maintaining the dryness and cleanliness of the quick connector's interior and ensuring the accuracy and stability of signal transmission. The gasket 8 acts as a buffer and shock absorber; when the locking sleeve 2 is abutted by the limiting structure during movement, it absorbs and disperses some energy, effectively reducing collisions or vibrations, and thus reducing the impact on internal electrical components and mechanical structures.

[0059] It should be noted that in this embodiment 1, the sealing element 7 is a waterproof ring, and its material includes, but is not limited to, silicone or rubber. The gasket 8 is a gasket, and its material includes, but is not limited to, metal or hard plastic. In other embodiments, the specific material and shape are not limited. The goal is to achieve the waterproof sealant's shock-absorbing effect.

[0060] Embodiment 2 of this utility model also relates to a wire, see below. Figure 1-6 As shown, the device includes a male connector unit 10, a female connector unit 20, and a cable body 30 connecting the two. The male connector unit 10 and / or the female connector unit 20 employs the quick-connect coupling described in Embodiment 1, allowing the locking sleeve 2 to expose the plug 11 for cable expansion. This method enables the connection to be achieved by providing a sliding locking sleeve 2 in either the male connector unit 10 or the female connector unit 20, making connection more convenient. Furthermore, with both locking sleeves 2 being sliding, there is no need to identify and locate the sliding locking sleeve 2 during use; simply picking up either end allows for operation, improving wiring efficiency. It should be noted that when the male connector unit 10 of one wire body 30 is plugged into another female connector unit 20, it is only necessary to keep one of the locking sleeves 2 exposed to the corresponding plug 11. The outer surface of the other plug 11 is provided with a protrusion 111. The protrusion 111 can be threaded into the rotating groove 22 in the locking sleeve 2 that wraps around the opposite plug 11 until it is locked into the locking hole 23 to achieve rotational locking, thereby achieving the connection and shielding of the two and preventing the plug 11 from being damaged by bumps.

[0061] The following section will take the sliding locking sleeve 2 of the male plug unit as an example for detailed explanation. (See also...) Figure 7-9 As shown, the male connector unit 10 includes a male locking sleeve 101, a male connector 102, and a male elastic element 103. The male locking sleeve 101, male connector 102, and male elastic element 103 correspond to the locking sleeve 2, connector 1, and elastic element 3 in Embodiment 1, respectively. Further, the male connector 102 includes a male plug pin 1021, a male housing 1022, and a male plug insulated wire 1023. The male plug pin 1021 and male housing 1022 have the same structure as the plug 11 and housing 12 in Embodiment 1, and will not be described in detail here. The male plug insulated wire 1023 is fixedly connected to the male housing 1022. The female connector unit 20 includes a female locking sleeve 201 and a female connector socket 202. The female connector 202 includes a female locking sleeve 201 and a female connector 1. The female connector 1 includes a female plug socket 2021, a female housing 2022 and a female plug insulated wire 2023. The female locking sleeve 201 is sleeved on the female housing 2022. The female locking sleeve 201 can rotate circumferentially relative to the housing 12. The female plug socket 2021 can be adapted to be plugged into the male plug pin 1021.

[0062] The male locking sleeve 101 has a male rotating groove 1011 on the side near the male plug pin 1021, and a male locking hole 1012 is provided at the end of the male rotating groove 1011. The female locking sleeve 201 has a female rotating groove 2011 on the end near the female plug seat 2021, and a female locking hole 2012 is also provided at the end of the female rotating groove 2011. The outer surface of the male plug pin 1021 is also provided with at least two male protrusions 1024. The number of female rotating grooves 2011 on the female locking sleeve 201 corresponds to or exceeds the number of male protrusions 1024, so that the male protrusions 1024 can be screwed into the female rotating grooves 2011. When the male protrusions 1024 rotate into the female locking hole 2012, the two are locked.

[0063] In some embodiments, the inner surface of the male plug pin 1021 is further provided with a first anti-misalignment structure 60, and the outer surface of the female plug socket 2021 is further provided with a second anti-misalignment structure 70 adapted to the first anti-misalignment structure 60. The first anti-misalignment structure 60 and the second structure include, but are not limited to, vertical ribs 701 and vertical grooves 601, protrusions 41 and recesses. In this embodiment 2, the first anti-misalignment structure 60 is a plurality of unevenly spaced vertical grooves 601, and the second anti-misalignment structure 70 is a vertical rib 701 corresponding one-to-one with the plurality of vertical grooves. When the male plug pin 1021 is inserted into the female plug socket 2021, the pin of the male plug pin 1021 will not be damaged when it is not aligned due to the presence of the first anti-misalignment structure 60 and the second anti-misalignment structure 70. Preferably, in order to improve the success rate of the male plug pin 1021 and the female plug socket 2021, axial marking marks can be provided on the outer surface of the male plug pin 1021 and the surface of the female housing 2022. The marking marks can be used to assist in alignment and improve the accuracy of the insertion.

[0064] Embodiment 3 of this utility model relates to a socket assembly, see reference. Figure 10-11As shown, the system includes a male socket 40, a female socket 50, and at least one cable. In a specific real-time scenario, the male socket 40 and female socket 50 are located on the stage light and control box, respectively. When there is only one cable, the male socket 40 is plugged into the female connector unit 20, and the female socket 50 is plugged into the male connector unit 10. When there are two or more cables, the male connector units 10 and female connector units 20 of the two or more cables are connected in a linear, staggered manner, with the female connector unit 20 at one end of the linear connection plugged into the male socket 40, and the male connector unit 10 at the other end of the linear connection plugged into the female socket 50. This configuration allows for flexible adjustment of the connection method, whether using a single cable or multiple cables, according to the actual usage scenario. In small areas, a single cable connecting male socket 40 and female socket 50 may be sufficient to meet the power supply needs of simple devices. However, in large data centers or outdoor shooting locations, where the space is larger and the equipment is more complexly distributed, using multiple cables connected in a linear, interwoven manner allows for flexible adjustment of the cable routing based on the specific location of the equipment, easily bypassing obstacles and enabling the socket assembly to adapt to various complex spatial layouts.

[0065] The male socket 40 includes a male base 401 and a male protective sleeve 402 covering the male base 401. The female socket 50 includes a female base 501 and a female protective sleeve 502 covering the female base 501. The male base 401 has the same structure as the male plug pin 1021 in Embodiment 2, and the male base 401 can be inserted into the female plug socket 2021 in Embodiment 2. The female base 501 has the same structure as the female plug socket 2021 in Embodiment 2, and the female base 501 can be inserted into the male plug pin 1021 in Embodiment 2. Meanwhile, the outer surface of the female protective sleeve 502 is provided with a female protective sleeve protrusion 5021 that matches the male locking hole 1012 of the male locking sleeve 101 in Embodiment 2, and can be screwed into the male rotating groove 1011 in Embodiment 2. The outer surface of the male protective sleeve 402 is provided with male protective sleeve protrusions 4021 that are adapted to the female rotating groove 2011 in Embodiment 2, and can be screwed into the female rotating groove 2011 in Embodiment 2. Similarly, the inner surface of the male protective sleeve 402 is provided with a male protective sleeve anti-mistake structure 4022 that is adapted to the first anti-mistake structure 60 in Embodiment 2, and the inner surface of the female protective sleeve 502 is provided with a female protective sleeve anti-mistake structure 5022 that is adapted to the second anti-mistake structure 70 in Embodiment 2. Therefore, the assembly and extension of multiple wires can be easily achieved through the above-mentioned adaptation structures, thus achieving the effect of wire expansion.

[0066] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0067] 1. By fitting the locking sleeve 2 onto the housing 12 and allowing it to slide axially, and in conjunction with the elastic element 3, when the elastic element 3 is in a compressed state, the locking sleeve 2 moves to expose the plug 11, thereby enabling convenient and rapid expansion of multiple wires and greatly improving the efficiency of wire connection. For example, on a film and television shooting set, when a scene needs to be quickly changed and the wires need to be extended, the staff can quickly operate the quick connector to complete the expansion, avoiding delays in the shooting schedule due to wire problems;

[0068] 2. Although it enables rapid expansion, the quick connector design does not sacrifice the locking function of the locking sleeve 2 itself and the device. During normal use, the elastic element 3 is in its initial state, the locking sleeve 2 is located at one end of the connector 1, and the plug 11 is located inside the locking sleeve 2. At this time, after the connector 1 is connected to the device, the locking sleeve 2 can lock with the device in the traditional way, preventing the connector from accidentally dislodging from the socket and ensuring the stability and safety of the connection.

[0069] 3. The quick connector has a simple structure and is easy to operate. The operator only needs to compress the elastic element 3 to move the locking sleeve 2, which exposes the plug 11 for expansion operation. No complicated tools or cumbersome steps are required. The operation is simple and convenient, reducing the technical requirements for operators. Even ordinary workers can easily get started.

[0070] 4. Because the male connector unit 10 and / or female connector unit 20 in the cable have quick-connect functions, the cable can adapt to more application scenarios with different length requirements. Whether it is a small indoor shooting or a large outdoor film and television production, the cable can be quickly and flexibly expanded according to actual needs, without the need to prepare a large number of custom cables of different lengths in advance, reducing costs and inventory pressure.

[0071] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
