Description

Technical Field

[0001] This invention relates to the field of connector technology, specifically to a quick-connect connector and connector assembly. Background Technology

[0002] Currently, connectors are increasingly used in various fields, but their installation is limited by space constraints. Existing mating connectors are subject to these limitations. For example, with the increasing automation and integration of equipment in underground mining operations, existing technologies suffer from problems such as the inability to use tooling for installation and low mating efficiency. To address these issues, there is an urgent need for a quick-mating connector structure that is convenient to use in confined spaces, offers high installation and usage efficiency, provides a secure connection, and meets the protection requirements for underground mining applications.

[0003] Existing technical solutions use traditional connection and fastening methods such as threaded fastening between sockets and panels, and plugs and sockets. This is not convenient for installation, use and replacement in narrow spaces. At the same time, there is a problem of incomplete threaded connection and sealing failure at the head and seat mating position. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a quick-connect connector and connector assembly, which enables quick connection and disconnection of the connector in narrow spaces, ensuring proper connection.

[0005] To achieve the above objectives, the technical solution adopted is: a quick-connect connector, including a socket and a plug that are axially mated together. The socket has a socket insulator, and the plug has a plug insulator. The connector also includes a deformable clip, which consists of a connecting part and two cantilever arms connected to both ends of the connecting part and extending longitudinally. The extended ends of the two cantilever arms are open. When the socket insulator extends into the plug insulator, a first groove is formed circumferentially on the outer surface of the socket insulator. Two elongated holes are provided on the plug insulator. When the plug insulator extends into the socket insulator, a first groove is formed circumferentially on the outer surface of the plug insulator. Two elongated holes are provided on the socket insulator. When the plug is fully mated, the two elongated holes can communicate with the first groove, so that the two cantilever arms of the clip can be engaged in the first groove through the elongated holes, thereby locking and fixing the socket and the plug.

[0006] The first groove described in this invention is an annular groove.

[0007] The cantilever described in this invention has a clearance fit with the first groove.

[0008] The portion of the cantilever that fits into the first groove in this invention is an arc-shaped portion that matches the curvature of the bottom of the first groove.

[0009] The two cantilever extensions of the present invention are bent in a direction away from each other so that the portions where the extensions connect with the arcuate portion form constricted portions that are close to each other.

[0010] When fully engaged, there is a gap between the connecting portion and the outer surface of the plug insulator as described in this invention.

[0011] The present invention provides a first O-ring between the end face of the socket insulator and the bottom face of the plug insulator. When the plug is inserted into place, the first O-ring is compressed by the end face of the socket insulator.

[0012] The plug insulator of the present invention has a first O-ring between the end face of the plug insulator and the bottom face of the socket insulator. When the plug is inserted into place, the first O-ring is compressed by the end face of the plug insulator.

[0013] The plug insulator and the socket insulator of the present invention are provided with a matching keyway and a positioning key.

[0014] The socket insulator of the present invention has a first annular groove along its circumference, and a second O-ring is installed in the first annular groove for sealing the socket insulator and the mounting position component.

[0015] A connector assembly includes the connector and a mounting panel for securing the connector. The mounting panel has a mounting cavity for axial insertion of the connector and a set of slotted holes for inserting two cantilevered inserts of a clip into an elongated hole.

[0016] The socket insulator of the present invention has a second groove along the circumferential direction on its outer surface for inserting a clip. The clip can be inserted into the second groove through the waist hole to fix the socket in the mounting cavity.

[0017] The second groove described in this invention is an annular groove.

[0018] The plug insulator of the present invention is provided with a colored strip that overlaps with the end face of the mounting panel when it is fully inserted.

[0019] When the connector and mounting panel of the present invention are installed in place, there is a gap between the connecting part and the outer surface of the mounting panel.

[0020] The plug insulator of the present invention has an arrow mark on its outer surface that is positionally related to the elongated hole.

[0021] The beneficial effects of this invention are:

[0022] 1. The connector in this application eliminates the need for threaded fastening. Only axial mating space and longitudinal insertion gap of the clip are required to ensure secure mating and locking of the connector. This makes it suitable for narrow working spaces where tooling is unavailable or inconvenient. It is easy to use, unrestricted by space, and separation is simple: just pull out the clip to axially separate the socket and plug. Installation and disassembly are quick and convenient, resulting in high operational efficiency and ease of use. Furthermore, the clip structure ensures a tight seal at the head-and-seat mating position, avoiding the sealing failure issues caused by incomplete screwing in existing threaded fastening solutions. The plug-cable assembly is compatible with sockets of different installation center distances, making it suitable for high-density socket installation scenarios in confined spaces.

[0023] 2. The first groove is designed as a ring groove, so there is no need to consider the correspondence between the first groove and the elongated hole when the socket and plug are inserted, thus ensuring the efficiency of the insertion and locking.

[0024] 3. Ensure a clearance fit between the cantilever and the first groove to prevent axial movement of the plug and socket and limit axial movement.

[0025] 4. The part where the cantilever contacts the first groove is designed as an arc-shaped part to increase the contact area between the two, improve the fixing effect, make the clip less likely to come out during use, and improve the fixing reliability.

[0026] 5. The front opening of the arc-shaped part is designed to expand outward, which serves as a guide when inserting, reduces the force when inserting the clip, facilitates assembly and alignment with the elongated hole, and allows the formed contraction part to be locked in the first groove, making it less likely to fall out, further improving the reliability of the fixation.

[0027] 6. By creating a gap between the connecting part and the plug insulator or mounting panel, the clips can be removed and pressed down directly without tools, resulting in high efficiency in removal and installation.

[0028] 7. The first O-ring added between the socket insulator and the plug insulator not only serves as a seal, but also, depending on the design position, can be used to axially compress the clip, so that the clip can be better fixed in the first groove under axial pressure, making the locking more stable.

[0029] 8. By using the matching keyway and positioning key, the socket and plug can be quickly aligned, and the alignment of the first groove and the elongated hole can be ensured.

[0030] 9. To ensure the sealing between the socket and the components at the installation location, a first annular groove and a second O-ring can be added to achieve sealed installation with components at different installation locations.

[0031] 10. The connector assembly of this application can be integrated into the mounting panel for one-piece installation, or the mounting position component can be used as the mounting panel. The connector and the mounting panel are fixed together using clips, as well as the plug and socket are fixed together. The structure is simple, not limited by space, and has high installation efficiency.

[0032] 11. Clips can be used to fix the socket to the mounting panel and can be removed. They can also be used for axial and radial limiting, making them convenient and quick to use.

[0033] 12. By setting the second groove as an annular groove, the circumferential position of the socket in the mounting panel can be ignored, and it can be used directly after installation and alignment.

[0034] 13. The color ribbon can be used to determine whether the plug and socket are properly inserted, making it easier for the clip to be inserted and for quick alignment in confined spaces.

[0035] 14. In a confined space, to facilitate quick determination of the positional relationship between the elongated hole and the waist hole, as well as the positional relationship between the elongated hole and the first groove, arrow markers are provided to facilitate quick insertion.

[0068] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are only used to distinguish similar objects and should not be construed as a specific order or sequence. It should be understood that such use can be interchanged where appropriate.

[0072] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly, for example, they can refer to fixed connections, detachable connections, mating connections, or integral connections. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0073] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0074] like Figure 1 , Figure 18 As shown, a quick-connect connector includes a socket 11 and a plug 12 that are axially mated together. The socket 11 is provided with a socket insulator 111, and the plug 12 is provided with a plug insulator 121. The mating of the socket 11 and the plug 12 includes two cases: in embodiment (1), the socket insulator 111 extends into the plug insulator 121, and in embodiment (2), the plug insulator 121 is inserted into the socket insulator 111.

[0075] Implementation method (1) as follows Figure 1 , Figure 2 , Figure 3As shown, when the socket 11 and plug 12 are inserted, the socket insulator 111 extends into the plug insulator 121. By inserting them into place, the contacts of the socket and the contacts of the plug are connected to achieve electrical connection. The connector also includes a deformable clip 13, which consists of a connecting part 131 and two cantilever arms 132 connected to both ends of the connecting part 131 and extending longitudinally. The extended ends of the two cantilever arms 132 are connected to an opening 133. A first groove 111-1 is provided circumferentially on the outer surface of the socket insulator 111. The structure of the first groove 111-1 ensures that the cantilever arms can be inserted smoothly. It can be two elongated grooves or annular grooves provided circumferentially. When the socket 11 and plug 12 are inserted, the alignment of the first groove 111-1 and the elongated hole 121-1 is ensured. Two transversely oriented elongated holes 121-1 are provided on the plug insulator 121, which are opened circumferentially. The elongated holes 121-1 ensure the structural stability of the plug insulator 121 and facilitate the insertion of the clip 13. Figure 5 , Figure 6 , Figure 7 As shown, when fully engaged, the two elongated holes 121-1 communicate with the first groove 111-1. The opening 133 of the clip 13 allows it to be inserted longitudinally into the elongated holes 121-1. The maximum insertion length is reached at the limit position, which refers to the position where the clip 13 cannot move further longitudinally under force. The two cantilever arms 132 are engaged into the first groove 111-1 through the elongated holes 121-1. At this point, the clip 13 clamps tightly against the first groove 111-1 and will not disengage from it, thus locking and securing the socket 11 and plug 12. Figure 1 , Figure 4 As shown, the first groove 111-1 is optimally an annular groove. The annular groove structure is easy to process and does not require consideration of alignment with the elongated hole 121-1. As long as it is properly inserted, the first groove 111-1 and the elongated hole 121-1 can be connected, making it more suitable for installation positions with limited space. Compared to the annular groove structure, the first groove 111-1 formed by two elongated grooves can prevent rotation between the plug 12 and the socket 11.

[0076] Implementation method (2) as follows Figure 18 , Figure 19 , Figure 20 As shown, when the socket 11 and the plug 12 are plugged in, the plug insulator 121 extends into the socket insulator 111. Compared with embodiment (1), the positions of the first groove 111-1 and the two elongated holes 121-1 are swapped. The first groove 111-1 is provided circumferentially on the outer surface of the plug insulator 121, and the two elongated holes 121-1 are provided on the socket insulator 111. The specific structure, principle, and how the first groove 111-1 and the elongated holes 121-1 cooperate with the clip 13 are the same as in embodiment (1).

[0077] like Figure 3 , Figure 20 As shown, the cantilever 132 is clearance-fitted with the first groove 111-1, that is, the axial width of the first groove 111-1 matches the cross-sectional size of the cantilever 132. When the cantilever 132 is inserted into the first groove 111-1, it restricts the axial displacement of the plug 12 and the socket 11, preventing further axial movement between them.

[0078] like Figure 25 , Figure 26 As shown, the portion of the cantilever 132 that engages with the first groove 111-1 is an arc-shaped portion 132-1 that matches the curvature of the bottom of the first groove 111-1. This structure, used in the arc-shaped groove, increases the contact area between the cantilever 132 and the first groove 111-1, increasing the reliability of the mating structure and making the fixation more reliable. The cross-section of the clip 13 can be circular, rectangular, or other shapes. The purpose of a circular clip is to reduce the resistance when inserting the clip and facilitate assembly.

[0079] like Figure 25 As shown, the extended ends of the cantilever 132 bend in a direction away from each other so that the portions connecting the extended ends with the arcuate portion 132-1 form converging portions 132-2 that are close to each other. The outward expansion of the extended ends of the cantilever 132 guides the insertion of the clip 13, reduces the force required for insertion, and facilitates assembly and use. The inward contraction of the front end of the arcuate portion 132-1 serves two purposes: first, to increase the contact area between the clip and the fixed position; and second, to prevent the clip from easily coming out during use, thus improving the reliability of the clip connection.

[0080] like Figure 1 , Figure 3 As shown, when the plug is fully engaged, even if the clip 13 reaches its limit position, there is a gap between the connecting part 131 and the outer surface of the plug insulator 121. This gap causes the clip 13 to form a handle shape after insertion, which is convenient for pulling out and pressing down. The installation and removal efficiency is high. The shape of the connecting part 131 can be adjusted according to the shape of the plug insulator 121.

[0081] like Figure 8 , Figure 10As shown, in embodiment (1), a first O-ring 14 is provided between the end face of the socket insulator 111 and the bottom face of the plug insulator 121. When the plug is inserted into place, the first O-ring 14 is compressed by the end face of the socket insulator 111. This compression provides a reaction force, so that the clip 13 can be stably installed in the first groove 111-1. The sealing function after the head seat is inserted is achieved by using an axial sealing O-ring. The specific insertion process is as follows: In the initial insertion stage, the distance L1 between the top surface of the socket insulator 111 and the bottom surface of the plug insulator 121 is greater than or equal to the diameter D1 of the first O-ring seal, and the first O-ring seal is not compressed; when the top surface of the socket insulator 111 begins to contact the first O-ring seal, the distance L1 between the top surface of the socket insulator 111 and the bottom surface of the plug insulator 121 is less than the diameter D1 of the first O-ring seal, and the first O-ring seal is compressed and deformed. At this time, the distance L2 between the opposite end faces of the first groove 111-1 and the elongated hole 121-1 is less than the cross-sectional diameter D2 of the clip, and the clip cannot be inserted. The headstock is inserted into the first groove 111-1 for assembly. As the headstock is inserted, when it is fully engaged, the distance L2 between the opposite end face of the first groove 111-1 and the elongated hole 121-1 is not less than the diameter D2 of the clip. The clip can then be inserted into the first groove 111-1 for assembly, locking and securing the engagement position. After the clip is assembled, the first O-ring resealable ring springs back. After springing back, the distance L2 between the opposite end face of the first groove 111-1 and the elongated hole 121-1 is equal to the diameter D2 of the clip. At this time, the first O-ring resealable ring inside the plug is in a compressed state, ensuring the sealing of the headstock engagement position.

[0082] like Figure 23 As shown, in embodiment (2), a first O-ring 14 is provided between the end face of the plug insulator 121 and the bottom face of the socket insulator 111. When the plug is inserted into place, the first O-ring 14 is compressed by the end face of the plug insulator 121. The structure and principle of the first O-ring 14 are the same as those in embodiment (1). The specific insertion process is basically the same as that in embodiment (1), except that the positions of the plug and the socket are changed.

[0083] like Figure 6 , Figure 7 , Figure 13 As shown, a matching keyway 121-2 and a positioning key 111-2 are provided between the plug insulator 121 and the socket insulator 111. The keyway 121-2 is located on the plug insulator 112, and the positioning key 111-2 is located on the socket insulator 111. The specific arrangement is not limited to reversing the positions of the keyway 121-2 and the positioning key 111-2. At the same time, the orientation of the keyway 121-2 and the positioning key 111-2 can be defined according to the usage requirements to ensure that the first groove 111-1 and the elongated hole 121-1 have a definite relative positional relationship.

[0084] like Figure 2 , Figure 4 As shown, a first annular groove 111-3 is provided on the socket insulator 111 along the circumferential direction. A second O-ring 15 is installed in the first annular groove 111-3. The second O-ring 15 is a radial O-ring and is used to seal the socket insulator 111 and the mounting position component. For example, in a connector assembly, a radial sealing O-ring is used to achieve the sealing function between the socket and the mounting panel 2.

[0085] like Figure 9 , Figure 10 , Figure 23 , Figure 24 As shown, a connector assembly includes a connector 1 and a mounting panel 2 for fixing the connector 1. The mounting panel 2 can be a standalone component used integrally with the connector 1, or it can be a mounting plate for mounting the connector on various devices. The mounting panel 2 has a mounting cavity 22 for the axial insertion of the connector 1. The socket 11 and the plug 12 are inserted into the mounting cavity 22. The mounting panel 2 has a set of waist holes 21 for inserting two cantilever arms 132 of a clip 13 into an elongated hole 121-1. That is, the two cantilever arms 132 first pass through the waist holes 21 and then insert into the elongated hole 121-1. Using a clip 13, the socket 11 and the plug 12 can be locked and fixed, and the plug 12 can also be fixed to the mounting panel 2 to prevent the connector from moving axially as a whole.

[0086] like Figure 9 , Figure 10 , Figure 11 , Figure 23 As shown, utilizing the working principle of the clip 13, the fixing stability of the connector is further improved. A second groove 111-4 for inserting the clip 13 is provided circumferentially on the outer surface of the socket insulator 111. The clip 13 can be inserted into the second groove 111-4 through the waist hole 21 to fix the socket 11 in the mounting cavity 22. This fixing method facilitates disassembly. The socket can also be fixed by using nuts, potting glue, etc.

[0087] like Figure 4 , Figure 21 As shown, the second groove 111-4 is an annular groove, and the second groove 111-4 has the same function and principle as the first groove 111-1.

[0088] like Figure 9 , Figure 23As shown, the plug insulator 121 is provided with a colored strip 121-3 that coincides with the end face of the mounting panel 2 when it is fully inserted. In actual installation and use, the socket is inserted from one end of the mounting cavity and the plug is inserted from the other end to be inserted into the socket in the mounting panel 2. In this case, it is not easy to determine whether it is fully inserted. By setting the colored strip, when the colored strip mark coincides with the end face of the mounting panel, it indicates that the head is fully inserted.

[0089] like Figure 12 As shown, when the clip 13 reaches its limit position, there is a gap between the connecting part 131 and the outer surface of the mounting panel 2. Using this gap, the clip 13 can be pulled out without tools, making installation and disassembly convenient and efficient.

[0090] like Figure 9 , Figure 23 As shown, due to space limitations, it is difficult to determine the relative positions of the elongated hole 121-1 and the waist hole 21, or the relative positions of the keyway 121-2 and the positioning key 111-2, from the mounting panel 2 when the head and base are inserted. By providing an arrow marker 121-4 on the outer surface of the plug insulator 121 that has a positional relationship with the elongated hole 121-1, accurate position determination can be achieved without trial or observation. The orientation of the arrow marker 121-4 can be defined according to usage requirements, ensuring the relative positional relationship with the elongated hole 121-1, the mating keyway 121-2, and the positioning key 111-2.

[0091] This application uses clips to fix the socket and mounting panel and lock the head unit after insertion, achieving an IPX8 seal between the socket housing and the mounting panel, and between the head unit mating surfaces. It features a simple structure, high installation efficiency in confined spaces, and reliable locking. Furthermore, by locking the head unit in place with clips, no special tooling is required, allowing for on-site plug removal and equipment maintenance, thus simplifying installation and use.

[0092] Unless otherwise specified in which implementation method the improved structure is applied, the other improved structures are applicable to both implementation methods.

[0093] The above are merely preferred embodiments of the present invention and are not intended to limit or restrict the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection declared by the present invention.
