Description

Technical Field

[0001] The invention relates to the technical field of connectors, in particular to a quick plug-in connector and a connector assembly. Background Art

[0002] At present, connectors are increasingly used in various fields. When used, they are limited by the installation space. Existing plug-in connectors are limited by the installation space. For example, with the improvement of automation and equipment integration in underground mine operations, existing technical solutions have problems such as the inability to use tooling for installation and low plug-in efficiency. In view of the above problems, there is an urgent need for a quick plug-in connector structure that is easy to plug in a narrow space, has high installation and use efficiency, is firmly connected, and has a protection level that meets the requirements for use in mines.

[0003] The existing technical solutions use traditional connection and fastening methods such as threaded fastening between the socket and the panel, and the plug and socket, which is not convenient for installation, use and replacement on site in narrow spaces. At the same time, there is a problem of failure of sealing at the head seat insertion position due to the threaded connection not being in place. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a quick plug-in connector and a connector assembly, which can realize quick plug-in and disconnection of the connector in a narrow space and ensure that it is plugged in place.

[0005] To achieve the above-mentioned purpose, the technical solution adopted is: a quick plug-in connector, including a socket and a plug that are axially plugged in, the socket is provided with a socket insulator, the plug is provided with a plug insulator, the connector also includes a deformable clip, the clip is composed of a connecting part and two cantilevers connected at both ends of the connecting part and extending longitudinally, there is an opening between the extended ends of the two cantilevers, a first groove or two long holes are circumferentially provided on the outer surface of the socket insulator, and two long holes or first grooves are correspondingly provided on the plug insulator, when the socket and the plug are plugged in place, the two long holes can be connected to the first groove, so that the two cantilevers of the clip can be inserted into the first groove through the long holes, thereby realizing the locking and fixation of the socket and the plug.

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

[0007] The cantilever described in the present invention is clearance-matched with the first groove.

[0008] The portion of the cantilever that is inserted into the first groove of the present invention is an arc-shaped portion that matches the arc of the groove bottom of the first groove.

[0009] The extending ends of the two cantilevers of the present invention are bent in directions away from each other so that the parts where the extending ends are connected to the arc-shaped parts form contraction parts that are close to each other.

[0010] When the clip is inserted and engaged in place, there is a gap between the connecting portion of the present invention and the outer surface of the plug insulator.

[0011] A first O-type sealing ring is arranged between the end surface of the socket insulator and the bottom surface of the plug insulator of the present invention. When plugged in place, the first O-type sealing ring is squeezed by the end surface of the socket insulator and is in a compressed state.

[0012] A first O-type sealing ring is arranged between the end surface of the plug insulator and the bottom surface of the socket insulator of the present invention. When plugged in place, the first O-type sealing ring is squeezed by the end surface of the plug insulator and is in a compressed state.

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

[0014] The socket insulator of the present invention is provided with a first annular groove along the circumferential direction, and a second O-type sealing ring is installed in the first annular groove for sealing the socket insulator and the installation position component.

[0015] A connector assembly comprises the connector and a mounting panel for fixing the connector, wherein the mounting panel is provided with a mounting cavity for the connector to penetrate axially, and a group of waist holes for two cantilevers of the clip to be inserted into the long holes.

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

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

[0018] The plug insulator of the present invention is provided with a color band which coincides with the end surface of the installation panel when the plug is plugged in place.

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

[0020] The outer surface of the plug insulator of the present invention is provided with an arrow mark having a positional relationship with the long hole.

[0021] The beneficial effects of the present invention are: 1. The connector of the present application no longer requires threaded fastening. It only needs to retain the axial plug-in space and the longitudinal insertion gap of the clip to ensure that the connector is plugged in and locked. It is suitable for narrow working spaces where tooling cannot be used or tooling is inconvenient to use. It is easy to use and not limited by space. When separating, you only need to pull out the clip and axially separate the socket and the plug. It is quick and convenient to install and disassemble, with high operation efficiency and easy to use. In addition, the sealing of the head seat plug-in position is ensured by fixing the clip structure, avoiding the problem of sealing failure due to inadequate screwing in the existing threaded fastening solution. The plug cable assembly is compatible with sockets with different installation center distances, and is suitable for high-density socket installation scenarios in narrow spaces.

[0022] 2. The first groove is designed as a ring groove, so there is no need to consider the corresponding relationship between the first groove and the long hole when the socket and the plug are plugged in, thereby ensuring the efficiency of the plug-in locking and fixing.

[0023] 3. Ensure that the cantilever and the first groove are in clearance fit to prevent the plug and socket from axial movement and limit axial movement.

[0024] 4. The contact portion between the cantilever and the first groove is designed to be an arc-shaped portion, thereby increasing the contact area between the two and improving the fixing effect, making it difficult for the clip to fall out during use, thereby improving the fixing reliability.

[0025] 5. The front end opening of the arc-shaped portion is designed to expand outward, which serves as a guide during insertion, reduces the force applied when the clip is inserted, facilitates assembly and alignment with the long hole, and enables the formed contraction portion to be stuck in the first groove and not easy to fall out, further improving the fixation reliability.

[0026] 6. There is a gap between the connection part and the plug insulator or the installation panel, so that when removing and installing the clip, it can be directly pulled out and pressed down without tools, and the removal and installation efficiency is high.

[0027] 7. The first O-ring added between the socket insulator and the plug insulator plays a sealing role. According to the designed position, the clip can be axially squeezed so that the clip can be better fixed in the first groove under the axial pressure, and the locking is more stable.

[0028] 8. By using the matching keyway and positioning key, the socket and the plug can be quickly aligned, and the alignment of the first groove and the long hole can be ensured.

[0029] 9. In order to ensure the sealing between the socket and the components at the installation position, a first ring groove and a second O-ring can be added to achieve sealed installation with components at different installation positions.

[0030] 10. The connector assembly of the present application can be installed in an integrated manner by integrating the connector on the installation panel, or the installation position component can be used as the installation panel, and the connector and the installation panel, as well as the plug and the socket can be fixed by clips. It has a simple structure, is not limited by space, and has high installation efficiency.

[0031] 11. The socket and the mounting panel can be fixed and removed by the clip, and the axial and radial limiting functions can be achieved, which is convenient and quick to use.

[0032] 12. The second groove is set as an annular groove, so there is no need to consider the circumferential position of the socket in the installation panel and the installation alignment direction, and it can be used directly.

[0033] 13. The color ribbon can be used to determine whether the plug and socket are properly inserted, which is convenient for the clip to be inserted and for quick judgment and alignment in a small space.

[0034] 14. In order to quickly determine the positional relationship between the long hole and the waist hole, as well as the positional relationship between the long hole and the first groove in a narrow space, arrow marks are set to facilitate quick insertion. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0042] like Figure 1 , Fig.18As shown, a quick plug connector includes a socket 11 and a plug 12 that are axially plugged together. The socket 11 is provided with a socket insulator 111, and the plug 12 is provided with a plug insulator 121. The plugging of the socket 11 and the plug 12 includes two situations: implementation mode (1) the socket insulator 111 extends into the plug insulator 121, and implementation mode (2) the plug insulator 121 is inserted into the socket insulator 111.

[0043] Implementation method (1) Figure 1 , Figure 2 , Figure 3 As shown, when the socket 11 and the plug 12 are plugged together, the socket insulator 111 extends into the plug insulator 121. By plugging into place, the contacts of the socket and the contacts of the plug are docked to achieve electrical connection. The connector also includes a deformable clip 13, which consists of a connecting portion 131 and two cantilevers 132 connected to both ends of the connecting portion 131 and extending longitudinally. An opening 133 is formed between the extended ends of the two cantilevers 132. A first groove 111-1 is circumferentially provided on the outer surface of the socket insulator 111. The structure of the first groove 111-1 ensures that the cantilever can be smoothly inserted. It can be two sections of elongated grooves provided along the circumference, or it can be an annular groove. When the socket 11 and the plug 12 are plugged into each other, the first groove 111-1 and the long hole 121-1 are aligned. The plug insulator 121 is provided with two long holes 121-1 which are arranged opposite to each other in the transverse direction and opened in the circumferential direction. The long 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 the two slots 121-1 are in full engagement, the two slots 121-1 are connected to the first groove 111-1, and the opening 133 of the clip 13 is used to insert the clip 13 longitudinally into the slot 121-1. The maximum insertion length is to reach the limit position, which refers to the position where the clip 13 cannot be moved longitudinally by force. The two cantilevers 132 are inserted into the first groove 111-1 through the slot 121-1. At this time, the clip 13 clamps the first groove 111-1 and will not detach from the first groove 111-1, thereby achieving locking and fixing of the socket 11 and the plug 12. Figure 1 , Figure 4 As shown, the first groove 111-1 is preferably an annular groove, which is easy to process and does not need to consider the alignment relationship with the long hole 121-1. As long as the first groove 111-1 is properly inserted into place, the connection between the first groove 111-1 and the long hole 121-1 can be ensured, which is more convenient for installation positions with limited space. Compared with the annular groove structure, the first groove 111-1 formed by the two-stage long groove structure can prevent the plug 12 and the socket 11 from rotating.

[0044] Implementation method (2) Fig.18 , Fig.19 , Fig. 20 As shown, when the socket 11 and the plug 12 are plugged together, the plug insulator 121 extends into the socket insulator 111. Compared with the embodiment (1), the positions of the first groove 111-1 and the two long holes 121-1 are exchanged, and the first groove 111-1 is opened along the circumferential direction on the outer surface of the plug insulator 121, and the two long holes 121-1 are provided on the socket insulator 111. The specific structure and principle of the first groove 111-1 and the long holes 121-1, as well as how to cooperate with the clip 13, are the same as those in the embodiment (1).

[0045] like Figure 3 , Fig. 20 As shown, the cantilever 132 is loosely matched 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, the axial displacement of the plug 12 and the socket 11 is limited to prevent further axial movement between the two.

[0046] like Fig.25 , Fig.26 As shown, the cantilever 132 is inserted into the first groove 111-1 at an arc portion 132-1 that matches the arc of the bottom of the first groove 111-1. This structure is used in an arc groove to increase the contact area between the cantilever 132 and the first groove 111-1, increase the reliability of the matching structure, and make the fixation more reliable. The cross section of the clip 13 can be circular, rectangular or other shapes. The purpose of the circular clip is to reduce the resistance when the clip is inserted and facilitate assembly.

[0047] like Fig.25 As shown, the extended end of the cantilever 132 is bent in a direction away from each other so that the portion where the extended end is connected to the arc portion 132-1 forms a contraction portion 132-2 that is close to each other. The extended end of the cantilever 132 expands outward to guide the insertion of the clip 13, reduce the force applied when the clip is inserted, and facilitate assembly and use. The front end of the arc portion 132-1 contracts inward, the first function is to increase the contact area between the clip and the fixed position, and the second function is to make it difficult for the clip to fall out during use, thereby improving the reliability of the clip connection and fixation.

[0048] like Figure 1 , Figure 3 As shown, when the clip 13 is inserted into place, even if the clip 13 reaches the limit position (that is, the clip 13 is inserted into the first groove 111-1), there is a gap between the connecting portion 131 and the outer surface of the plug insulator 121. This gap allows the clip 13 to form a handle shape after insertion, which is convenient for pulling out and pressing down, and the installation and removal efficiency is high. The shape of the connecting portion 131 can be adjusted according to the shape of the plug insulator 121.

[0049] like Figure 8 , Fig.10 As shown, in implementation mode (1), a first O-ring 14 is provided between the end surface of the socket insulator 111 and the bottom surface of the plug insulator 121. When the plug is inserted into place, the first O-ring 14 is squeezed by the end surface of the socket insulator 111 and is in a compressed state. The compressed state provides a reaction force, so that the clip 13 can be firmly installed in the first groove 111-1, and an axial sealing O-ring is used to realize the sealing function after the head seat is inserted. The specific plugging 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, and the first O-ring is not compressed; when the top surface of the socket insulator 111 begins to contact the first O-ring, 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, and the first O-ring is compressed and deformed. At this time, the distance L2 between the opposite end surfaces of the first groove 111-1 and the long hole 121-1 is less than the cross-sectional diameter D2 of the clip, and the clip cannot be inserted. Insert it into the first groove 111-1 for assembly; as the head seat is inserted into the process, when the head seat is inserted into place, the relative end face distance L2 between the first groove 111-1 and the long hole 121-1 is not less than the clip cross-sectional diameter D2, and the clip can be inserted into the first groove 111-1 for assembly, and the insertion position is locked and fixed; after the clip is assembled, the first O-ring rebounds, and after the rebound, the relative end face distance L2 between the first groove 111-1 and the long hole 121-1 is equal to the clip cross-sectional diameter D2; at this time, the first O-ring in the plug is in a compressed state, ensuring the sealing of the head seat insertion position.

[0050] like Fig.23 As shown, in implementation mode (2), a first O-ring 14 is provided between the end surface of the plug insulator 121 and the bottom surface of the socket insulator 111. When the plug is plugged in, the first O-ring 14 is squeezed by the end surface of the plug insulator 121 and is in a compressed state. The structure and principle of the first O-ring 14 are the same as those in implementation mode (1). The specific plugging process is basically the same as that in implementation mode (1), except that the positions of the plug and the socket are swapped.

[0051] like Figure 6 , Figure 7 , Fig.13As shown, a matching key slot 121-2 and a positioning key 111-2 are provided between the plug insulator 112 and the socket insulator 111. In the figure, the key slot 121-2 is arranged on the plug insulator 112, and the positioning key 111-2 is arranged on the socket insulator 111. The specific arrangement form is not limited to reversing the arrangement positions of the key slot 121-2 and the positioning key 111-2. At the same time, the orientation of the key slot 121-2 and the positioning key 111-2 can be defined according to the requirements of use to ensure that the first groove 111-1 and the long hole 121-1 have a certain relative position relationship.

[0052] like Figure 2 , Figure 4 As shown, a first annular groove 111-3 is circumferentially provided on the socket insulator 111, and a second O-ring 15 is installed in the first annular groove 111-3. The second O-ring 15 is a radial O-ring, which is used for sealing the socket insulator 111 and the mounting position components. For example, in the connector assembly, a radial sealing O-ring is used to achieve the sealing function between the socket and the mounting panel 2.

[0053] like Fig. 9 , Fig.10 , Fig.23 , Fig.24 As shown, a connector assembly includes the connector 1 and a mounting panel 2 for fixing the connector 1. The mounting panel 2 can be an independent component used together with the connector 1, or a mounting plate for various devices to install the connector. The mounting panel 2 is provided with a mounting cavity 22 for the connector 1 to axially penetrate. The socket 11 and the plug 12 are plugged in the mounting cavity 22. The mounting panel 2 is provided with a group of waist holes 21 for the two cantilevers 132 of the clip 13 to be inserted into the long hole 121-1, that is, the two cantilevers 132 first pass through the waist holes 21 and then insert into the long hole 121-1. Using a clip 13 can realize the locking and fixing of the socket 11 and the plug 12, and can also fix the plug 12 to the mounting panel 2 to prevent the overall axial movement of the connector.

[0054] like Fig. 9 , Fig.10 , Fig.11 , Fig.23 As shown, the principle of using the clip 13 is used to further improve the fixing stability of the connector. A second groove 111-4 for inserting the clip 13 is opened along the circumferential direction 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 installation cavity 22. This kind of fixation is easy to disassemble, and the socket can also be fixed by nut tightening, glue filling, etc.

[0055] like Figure 4 , Fig.21As shown, the second groove 111 - 4 is an annular groove, and the function and principle of the second groove 111 - 4 are the same as those of the first groove 111 - 1 .

[0056] like Fig. 9 , Fig.23 As shown, the plug insulator 121 is provided with a color band 121-3 which coincides with the end face of the mounting panel 2 when plugged into place. During 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 plugged with the socket in the mounting panel 2. In this case, it is not easy to judge whether it is plugged into place. By setting the color band, when the color band mark coincides with the end face of the mounting panel, it indicates that the head seat is plugged into place.

[0057] like Fig.12 As shown, when the clip 13 reaches the extreme position (i.e. the connector and the mounting panel are installed in place), there is a gap between the connecting portion 131 and the outer surface of the mounting panel 2. By utilizing this gap, no tools are required when the clip 13 is pulled out, which makes installation and disassembly convenient and efficient.

[0058] like Fig. 9 , Fig.23 As shown, due to installation space limitations, when the header is plugged in, it is difficult to determine the relative positions of the long hole 121-1 and the waist hole 21, or the relative positions between the key slot 121-2 and the positioning key 111-2 in the installation panel 2. By providing an arrow mark 121-4 having a positional relationship with the long hole 121-1 on the outer surface of the plug insulator 121, the position can be accurately determined without trying or observing. The direction of the arrow mark 121-4 can be defined according to the use requirements, and the relative positional relationship between the long hole 121-1, the matching key slot 121-2 and the positioning key 111-2 needs to be ensured.

[0059] This application uses a clip to fix the socket and the mounting panel and lock the header after plugging, and realizes the IPX8 sealing function between the socket housing and the mounting panel, and between the header mating surfaces. It has the characteristics of simple structure, high installation efficiency in narrow spaces, and reliable plugging and locking. At the same time, the header is locked and fixed by the clip after plugging, without the need for special tooling, and the plug can be disassembled and the equipment can be repaired at the site of use, achieving the purpose of convenient installation and use.

[0060] Except for structures specifically specified to be applied to a certain embodiment, other improved structures are applicable to both embodiments.

[0061] The above are only preferred embodiments of the present invention and are not intended to limit or restrict the present invention. For researchers or technicians in this field, the present invention may have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection declared by the present invention.
