TECHNICAL FIELD
[0001] The utility model relates to a kind of anti-misassembly connector used when two components are connected, and the connecting structure comprising the anti-misassembly connector. BACKGROUND
[0002] Currently, the connector formed by the engagement of plug member and socket member is widely used for the connection between two components, such as the connection of components in assembling furniture or the connection of automotive interior components.
[0003] Prior art: a connector disclosed in Chinese Utility Model Patent No. CN221407893U includes a plug member and a socket member. The plug member includes at least one pair of elastic clips, each of which has a claw portion facing the outer side of the plug member. The socket member includes at least one pair of opening portions engaged with the elastic clips. The claw portion includes a claw surface engaged with the claw portion engaging side in the insertion direction and a release side inclined surface engaged in the release sliding direction. The opening portion includes a first step portion engaged with the claw surface of the claw portion engaging side and a second step portion engaged with the release side inclined surface. After the plug member is inserted into the socket member, the engagement of the plug member and the socket member is achieved by the engagement of the first step portion and the claw surface. In the state of engagement of the plug member and the socket member, the engagement of the release side inclined surface and the second step portion is released by operating the plug member relative to the socket member along the release sliding direction. In this state, the plug member is separated from the socket member by moving the plug member relative to the socket member along the insertion direction. However, the existing connector has the following defects in actual use.
[0004] 1. In the release sliding direction, the claw portion is provided with a release side inclined surface at only one end. Thus, if one of the plug member and the socket member is installed in reverse by 180° during assembly, the release side inclined surface will no longer function when the plug member is operated relative to the socket member along the release sliding direction in the state of engagement of the plug member and the socket member, and the plug member cannot be separated from the socket member.
[0005] 2. In the plug member, the main body of the plug member is a cross-shaped thin-walled structure composed of a first wall portion and a second wall portion, and the installation portion is integrally provided on both sides of the first wall portion. A fastener such as a screw passes through the installation hole of the installation portion to fix and install the plug member. Therefore, the overall strength of the plug member with a thin-walled structure is insufficient, and the plug member is easily twisted and deformed due to stress when the plug member is fixed with a screw, which causes it to not be well engaged with the socket member in subsequent use. SUMMARY
[0006] In view of the above-mentioned defects of the prior art, the utility model discloses a prevent mistaken installation connector, can effectively avoid one of plug component and socket component is 180 ° reverse installation.
[0007] In order to realize above-mentioned purpose, the utility model provides a prevent mistaken installation connector, including the plug component with plug main part, and the socket component with connecting cavity, the plug main part is inserted in the connecting cavity, and with the socket component detachable connection, the direction of inserting the plug main part into the connecting cavity is defined as the insertion direction, the direction of operating the plug component movement when the connection of the plug main part and the socket component is released is defined as the release sliding direction;
[0008] Along the insertion direction, the end of the plug main part close to the connecting cavity cavity bottom is plug bottom, the plug component is equipped with the positive installation avoidance empty area on one side of the plug bottom, and the installation positioning surface is equipped on the side of the plug main part away from the positive installation avoidance empty area, and the installation positioning surface extends straight along the insertion direction.
[0009] The inside of the socket component is equipped with the positioning wall and the mistaken installation prevention protruding portion on both sides of the connecting cavity respectively, the positioning wall extends straight along the insertion direction, and the mistaken installation prevention protruding portion protrudes from the cavity bottom of the connecting cavity to the plug component.
[0010] When the plug main part is inserted into the connecting cavity in the positive installation state of the plug component and the socket component, the installation positioning surface is close to the positioning wall, and the positive installation avoidance empty area is opposite the mistaken installation prevention protruding portion along the insertion direction and allows the plug main part to be inserted into place in the connecting cavity.
[0011] When the plug main part is inserted into the connecting cavity in the reverse installation state of the plug component and the socket component, the side of the plug main part equipped with the positive installation avoidance empty area is close to the positioning wall, and the installation positioning surface is opposite the mistaken installation prevention protruding portion along the insertion direction and can abut against the mistaken installation prevention protruding portion, thereby limiting the plug main part to be inserted into place in the connecting cavity.
[0012] The connector of the application is prevented from being misassembled. The plug member is provided with a positive assembly avoiding empty area and an installation positioning surface, and the socket member is provided with a positioning wall and a misassembly preventing protrusion. The plug main body can be inserted into the connecting cavity only in the positive assembly state of the plug member and the socket member, and the connection of the plug member and the socket member is completed. If the connection is carried out in the reverse assembly state of the plug member and the socket member, the installation positioning surface on the plug member will abut against the misassembly preventing protrusion in the socket member during the insertion of the plug main body into the connecting cavity, thereby limiting the further insertion of the plug main body, so that the plug main body cannot be inserted into the connecting cavity, and the connection of the plug member and the socket member cannot be completed. After such setting, the plug member and the socket member in the application can be connected only in the positive assembly state, the reverse assembly of one of the plug member and the socket member by 180° is effectively avoided, and the subsequent connection of the two is ensured to be smoothly released.
[0013] Further, the insertion direction is orthogonal to the release sliding direction; the plug member is provided with a plug inclined surface on one side of the plug bottom, and the plug inclined surface is distributed on the top of the positive assembly avoiding empty area; the socket member is provided with a socket inclined surface on the top of the misassembly preventing protrusion; the inclination directions of the plug inclined surface and the socket inclined surface are consistent, and both extend in a manner that the farther from the connecting cavity cavity bottom, the closer to the release sliding direction. In the connected state of the plug member and the socket member, the plug inclined surface and the socket inclined surface can be in abutment or not in contact, and there is a small gap therebetween; then, in the connected state of the plug member and the socket member, when the plug member slides relative to the socket member along the release sliding direction, the plug inclined surface will slide along the socket inclined surface. Based on the inclination of the plug inclined surface and the socket inclined surface, when the plug member moves relative to the socket member along the release sliding direction, the plug member will also move relative to the socket member along a direction opposite to the insertion direction, which is more convenient for the operation of releasing the connection of the plug member and the socket member, and improves the disassembly of the plug member from the socket member.
[0014] Further, the detachable connection structure between the plug body and the socket member preferably has the following structure: the insertion direction is orthogonal to the disengagement sliding direction; the plug body is provided with at least one pair of elastic clips, each of the elastic clips is provided with a clamping claw portion on the outer surface thereof, the surface of each of the clamping claw portions is provided with a clamping surface on the reverse side of the insertion direction and a disengagement inclined surface on the same side of the disengagement sliding direction; the socket member is provided with a socket opening portion for clamping each of the elastic clips, and each of the socket opening portions is provided with a first step portion and a second step portion on the side thereof; after the plug body is inserted into the connecting cavity in the normal state of the plug member and the socket member, the clamping surface is clamped with the first step portion, and the disengagement inclined surface is clamped with the second step portion, thereby limiting the disengagement of the plug body from the connecting cavity and achieving the clamping connection between the plug member and the socket member; when the plug member is moved relative to the socket member along the disengagement sliding direction in this state, the disengagement inclined surface slides along the second step portion, and the clamping between the disengagement inclined surface and the second step portion and the clamping between the clamping surface and the first step portion are both released, thereby driving the elastic clips to disengage from the socket opening portion, and at this time, the plug body can be pulled out of the connecting cavity, thereby releasing the clamping connection between the plug member and the socket member.
[0015] Further, the plug member is fixedly provided with a plug cover plate on the end side of the plug body away from the plug bottom, both sides of the plug cover plate have plug mounting portions protruding from the plug body, and plug mounting holes are formed in the plug mounting portions. By screwing fasteners such as screws into the plug mounting holes, the plug member is fixedly mounted on the connected member (i.e., the first connection body described below); at the same time, the plug cover plate forming the plug mounting portion has a plate structure and has good structural strength, thereby avoiding the distortion of the plug cover plate when the plug member is fixed by screws, improving the fixing reliability of the plug member, and ensuring that the plug member can be effectively detachably connected with the socket member after being fixedly mounted.
[0016] Further, the plug body includes a pair of plug main plates arranged opposite to each other and a plurality of reinforcing plates fixedly arranged between the pair of plug main plates, each of the plug main plates is provided with a plug opening portion at each of the elastic clips, and each of the elastic clips integrally extends away from the plug bottom from the side of the plug opening portion close to the plug bottom, and the area between the pair of plug main plates and the plug opening portion allows the elastic deformation of the elastic clips. In this way, the plug body itself has good structural strength, which improves the overall structural strength of the plug member itself, avoids the distortion of the plug member when the plug member is fixed by screws, and also improves the clamping connection strength between the plug member and the socket member.
[0017] Further, the socket member is provided with a socket bottom plate distributed on the bottom of the connecting cavity, and one end of the socket opening part extends to the socket bottom plate along the insertion direction, so that the socket opening part is an inverted U-shaped space facing the socket bottom plate, and the elastic clamping of the card in the socket opening part is more easily realized.
[0018] Further, the socket bottom plate has socket mounting parts extending from the connecting cavity on both sides, and socket mounting holes are formed in the socket mounting parts. By screwing fasteners such as screws into the socket mounting holes, the socket member is fixedly mounted on the connected part (i.e., the second connecting body described below).
[0019] Further, at least one of the plug member and the socket member is provided with an identification part on the surface thereof for identifying the disengaging sliding direction, and the identification part is an identification arrow or an identification recess. The provision of the identification part facilitates the user to operate the plug member to move along the disengaging sliding direction when disengaging the plug member from the socket member.
[0020] Further, the plug member and the socket member are integrally formed, which improves the structural strength of the plug member and the socket member, and thus improves the clamping connection strength between the plug member and the socket member.
[0021] The application also provides a connecting structure comprising a first connecting body and a second connecting body, and the above-mentioned mistaken-assembly-preventing connector, first and second counterbores are respectively arranged on the opposite surfaces of the first and second connecting bodies, the plug member is fixed in the first counterbores of the first connecting body, and the socket member is fixed in the second counterbores of the second connecting body, and the first and second connecting bodies are connected through the connection of the plug member and the socket member.
[0022] As described above, the mistaken-assembly-preventing connector and the connecting structure have the following beneficial effects:
[0023] The anti-misinstallation connector disclosed in this application achieves this by providing a proper alignment clearance area and mounting positioning surface on the plug component, and a positioning wall and anti-misinstallation protrusion on the socket component. This ensures that the plug body can only be inserted into the connection cavity and the connection between the plug and socket components when they are in the proper alignment state. If the connection is attempted when the plug and socket components are in the reverse alignment state, the mounting positioning surface on the plug component will abut against the anti-misinstallation protrusion in the socket component during the insertion of the plug body into the connection cavity, thereby restricting further insertion of the plug body and preventing it from being inserted into the connection cavity, thus preventing the connection between the plug and socket components from being completed. This design ensures that the plug and socket components in this application can only be connected in the proper alignment state, effectively preventing one of the plug and socket components from being reversed 180°, and ensuring that the connection can be smoothly disengaged subsequently.

[0068] The present application provides a misconnection prevention connector and a connection structure comprising the misconnection prevention connector. The misconnection prevention connector is used to detachably connect two components connected to each other; for the purpose of description, the two components connected by the misconnection prevention connector are defined as a first connection body and a second connection body, the first connection body and the second connection body can be a panel component of furniture, or an interior component of a car, or other components to be connected. The connection structure disclosed in the present application comprises a first connection body, a second connection body, and a misconnection prevention connector, and the misconnection prevention connector realizes the detachable connection between the first connection body and the second connection body.
[0069] As Figures 1 to 4As shown, the anti-misinstallation connector involved in this application includes a plug member 100 with a plug body 11 and a socket member 200 with a connecting cavity 21. The plug member 100 is fixedly installed on a first connecting body, and the socket member 200 is fixedly installed on a second connecting body. The opening of the connecting cavity 21 of the socket member 200 faces the plug member 100. The plug body 11 can be inserted into the connecting cavity 21 and can be detachably connected to the socket member 200. This enables the plug body 11 of the plug member 100 and the socket member 200 to be inserted or uninserted, thereby achieving a detachable connection between the plug member 100 and the socket member 200. Finally, the first connecting body and the second connecting body are detachably connected.
[0070] Furthermore, the direction in which the plug body 11 is inserted into the connecting cavity 21 is defined as the insertion direction, and the direction in which the plug member 100 moves when the connection between the plug body 11 and the socket member 200 is defined as the release sliding direction. In this embodiment, the insertion direction and the release sliding direction are orthogonal to each other; Figure 4 Taking the view angle as an example, the insertion direction is... Figure 4 The downward direction of the paper in the view is the direction in which the plug component 100 faces the socket component 200; the release sliding direction is... Figure 4 The left direction of the paper in the view. Furthermore, the direction orthogonal to both the insertion direction and the release sliding direction is defined as the front-back direction, which is also the... Figure 4 The front and back sides of the paper in the view.
[0071] like Figures 1 to 4 ,as well as Figures 5 to 7 As shown, along the insertion direction, the lower end of the plug body 11 near the bottom of the connecting cavity 21 is the plug bottom 111; the plug bottom 111 is located on one side in the left-right direction (e.g., Figure 4 Removing a portion (from the left side of the view) results in the left side of the plug bottom 111 being further away from the bottom of the connecting cavity 21 than the right side, creating a positive mounting clearance area 12 on one side of the plug bottom 111. This positive mounting clearance area 12 is formed by removing a portion of the lower left end of the plug body 11. In the left-right direction, the side of the plug body 11 furthest from the positive mounting clearance area 12 (e.g., the side away from the positive mounting clearance area 12) Figure 4 The right side of the view has a mounting positioning surface 112, which extends straight up and down along the insertion direction.
[0072] like Figures 1 to 4 ,as well as Figures 9 to 11 As shown, the socket component 200 has a positioning wall 22 and an anti-misinstallation protrusion 23 on the left and right sides of the connecting cavity 21, respectively. The positioning wall 22 extends straight up and down along the insertion direction, and the anti-misinstallation protrusion 23 protrudes upward from the bottom of the connecting cavity 21 toward the plug component 100.
[0073] When connecting the plug component 100 and the socket component 200, such as Figure 12 As shown, the plug body 11 of the plug component 100 is inserted downwards into the connecting cavity 21 of the socket component 200, and during the insertion process, the plug body 11 remains in close contact with the positioning wall 22, serving a positioning function. During the downward insertion of the plug body 11 into the connecting cavity 21, if the plug component 100 and the socket component 200 are in a correct orientation, that is, the correct orientation clearance area 12 of the plug component 100 and the anti-misalignment protrusion 23 of the socket component 200 are distributed on the same side in the left-right direction, for example, both on the left or both on the right; Figure 12 Taking the example where both the correct insertion clearance area 12 and the anti-misinstallation protrusion 23 are located on the left side in the view, when the plug body 11 is inserted downwards in this state, the mounting positioning surface 112 on the right side of the plug body 11 slides downwards against the positioning wall 22. The correct insertion clearance area 12 at the lower left end of the plug body 11 is always directly aligned with the anti-misinstallation protrusion 23 along the insertion direction. Due to the setting of the correct insertion clearance area 12 at the lower left end of the plug body 11, the lower left end of the plug body 11 avoids contact and conflict with the anti-misinstallation protrusion 23 during the downward insertion of the plug body 11 into the connecting cavity 21, thereby allowing the plug body 11 to be inserted downwards into place in the connecting cavity 21. Figure 12 As shown, the plug component 100 and the socket component 200 can be smoothly connected in the correct installation state. The plug body 11 being inserted into the connection cavity 21 means that the plug body 11 is engaged with the socket component 200 in this state, that is, the engagement claw portion 14 is engaged with the first step portion 241 and the second step portion 242; at the same time, in this state, the lower left end of the plug body 11 can just abut against the anti-misinstallation protrusion 23, or it can not be in contact, with a small gap between them.
[0074] Conversely, during the process of inserting the plug body 11 downwards into the connecting cavity 21, if the plug component 100 and the socket component 200 are in a reversed state, that is, the forward-mounted clearance area 12 of the plug component 100 and the anti-misinstallation protrusion 23 of the socket component 200 are distributed on different sides in the left-right direction, for example, the forward-mounted clearance area 12 is distributed on the left and the anti-misinstallation protrusion 23 is distributed on the right, or the forward-mounted clearance area 12 is distributed on the right and the anti-misinstallation protrusion 23 is distributed on the left; Figure 13Taking the example where the correct mounting clearance area 12 is located on the right and the anti-misinstallation protrusion 23 is located on the left in the view, when the plug body 11 is inserted downwards in this state, the right side of the plug body 11 with the correct mounting clearance area 12 slides downwards against the positioning wall 22, while the mounting positioning surface 112 of the plug body 11 is always directly facing the anti-misinstallation protrusion 23 along the insertion direction. Therefore, after the plug body 11 is inserted downwards a certain distance, the lower end of the mounting positioning surface 112 of the plug body 11 will abut against the anti-misinstallation protrusion 23, interfering with the further downward insertion of the plug body 11. This restricts the plug body 11 from being inserted into the connecting cavity 21, preventing the plug body 11 from engaging with the socket component 200. Figure 13 As shown, the plug component 100 and the socket component 200 cannot be connected when they are installed in reverse. The user can then determine that one of the plug component 100 and the socket component 200 has been installed in reverse and needs to be reinstalled.
[0075] In the anti-misinstallation connector involved in this application, by providing a positive mounting clearance area 12 and a mounting positioning surface 112 on the plug component 100, and providing an anti-misinstallation protrusion 23 and a positioning wall 22 on the socket component 200, the plug body 11 can only be inserted into the connection cavity 21 when the plug component 100 and the socket component 200 are in the positive mounting state, thus completing the connection between the plug component 100 and the socket component 200. If the connection is performed when the plug component 100 and the socket component 200 are in the reverse mounting state, the mounting positioning surface 112 on the plug component 100 will abut against the anti-misinstallation protrusion 23 in the socket component 200 during the insertion of the plug body 11 into the connection cavity 21, thereby restricting the further insertion of the plug body 11, making it impossible for the plug body 11 to be inserted into the connection cavity 21, and thus making it impossible to complete the connection between the plug component 100 and the socket component 200. With this configuration, the plug component 100 and the socket component 200 in this application can only be connected in the correct orientation, effectively preventing one of the plug component 100 and the socket component 200 from being reversed 180°, and ensuring that the two can be successfully disconnected later.
[0076] The preferred structures of the plug component 100 and the socket component 200 are described below.
[0077] like Figures 5 to 7As shown, the plug component 100 also includes a plug cover plate 15, which extends horizontally in the left-right direction and is integrally fixed to the upper end of the plug body 11 away from the plug bottom 111. In the left-right direction, the plug cover plate 15 has plug mounting portions 151 extending outward from the plug body 11 on both the left and right sides, and plug mounting holes 152 extending vertically through the plug mounting portions 151 on both sides are provided; the plug component 100 is fixedly mounted on the first connecting body by screwing screws or other fasteners into the plug mounting holes 152. Preferably, a first countersunk hole is provided on the opposite surface of the first connecting body facing the second connecting body. After the plug component 100 is fixed in the first countersunk hole of the first connecting body, the plug cover plate 15 is accommodated in the first countersunk hole, so that the lower surface of the plug cover plate 15 is flush with the opposite surface of the first connecting body facing the second connecting body.
[0078] like Figures 9 to 11 As shown, the opening of the connecting cavity 21 of the socket component 200 faces upward, and the socket component 200 is provided with a socket base plate 25 distributed at the bottom of the connecting cavity 21. In the left-right direction, the left and right sides of the socket base plate 25 have socket mounting portions 251 extending outward from the connecting cavity 21, and the socket mounting portions 251 on the left and right sides have socket mounting holes 252 that pass through vertically. By screwing screws or other fasteners into the socket mounting holes 252, the socket component 200 is fixedly mounted on the second connecting body. Preferably, the second connecting body has a second countersunk hole on the surface opposite to the first connecting body. After the socket component 200 is fixed in the second countersunk hole of the second connecting body, the entire socket component 200 is accommodated in the second countersunk hole, so that the upper surface of the socket component 200 is flush with the surface opposite to the first connecting body of the second connecting body.
[0079] Preferably, the plug mounting hole 152 on the plug component 100 and the socket mounting hole 252 on the socket component 200 are both countersunk holes to prevent the screw head from protruding. Furthermore, in other embodiments, the plug cover 15 and the first connecting body, and the socket component 200 and the second connecting body, can also be fixed by adhesive bonding. In this case, the plug cover 15 does not need to have a plug mounting hole 152, and the socket base plate 25 does not need to have a socket mounting hole 252.
[0080] Furthermore, the preferred structure for the detachable connection between the plug body 11 and the socket component 200 is as follows: Figures 5 to 7As shown, the plug body 11 has two pairs of elastic clips 13, one on the left and one on the right. Each pair of elastic clips 13 consists of two elastic clips 13 arranged symmetrically front to back; therefore, the plug body 11 has four elastic clips 13. Each elastic clip 13 has a locking claw portion 14 on its outer surface. The locking claw portion 14 is an outwardly projecting structure protruding outward from the outer surface of the elastic clip 13 in the front-back direction. Each locking claw portion 14 has a locking surface 141 on the opposite side (i.e., the upper side) of the insertion direction and a releasing inclined surface 142 on the same side (i.e., the left side) of the release sliding direction. The releasing inclined surface 142 extends inclined towards the release sliding direction and closer to the elastic clip 13. Therefore, the releasing inclined surface 142 on the rear side of the plug body 11 extends inclined to the left front, and the releasing inclined surface 142 on the front side of the plug body 11 extends inclined to the left rear. Figures 9 to 11 As shown, the socket component 200 has four socket openings 24, which correspond one-to-one with and engage with four elastic clips 13. All four socket openings 24 are connected to the connecting cavity 21. Each socket opening 24 has a first step 241 on its upper side and a second step 242 on its left side. In this embodiment, the first step 241 is formed by the left and right edges extending from the upper side of the socket opening 24, and the second step 242 is formed by the right and left edges extending from the left side of the socket opening 24.
[0081] After the plug body 11 is inserted into the connecting cavity 21 in the upright position of the plug component 100 and the socket component 200, as follows: Figure 1 and Figure 3 As shown, the engaging surface 141 on the upper side of the engaging claw portion 14 engages with the first step portion 241 (i.e., the first step portion 241 is distributed on the upper side of the engaging surface 141), and the releasing tilt surface 142 on the left side of the engaging claw portion 14 engages with the second step portion 242 (i.e., the second step portion 242 is distributed on the left side of the releasing tilt surface 142), thereby restricting the plug body 11 from disengaging from the connecting cavity 21 and realizing the engaging connection between the plug member 100 and the socket member 200.
[0082] With the plug member 100 and the socket member 200 engaged, when the plug member 100 is moved to the left relative to the socket member 200 along the release sliding direction, the tilting setting of the release inclined surface 142 and its contact with the second step portion 242 cause each elastic clip 13 to elastically deform in the front-back direction toward the inside of the plug body 11, i.e., the front elastic clip 13 elastically deforms backward and the rear elastic clip 13 elastically deforms forward, until the engagement between the release inclined surface 142 and the second step portion 242 and the engagement between the engagement surface 141 and the first step portion 241 are released, causing the elastic clip 13 to disengage from the socket opening portion 24. At this time, the plug body 11 can be pulled upward from the connecting cavity 21, thereby releasing the engagement connection between the plug member 100 and the socket member 200.
[0083] Preferably, such as Figures 5 to 7 As shown, in the engaging claw portion 14, the engaging surface 141 is an outwardly and downward inclined surface; as Figure 3 As shown, the angle α of the engaging surface 141 relative to the horizontal plane is 10–30°, and the engaging surface 141 is smoothly connected to the remaining surfaces of the engaging claw portion 14 via curved surfaces. Figure 8 As shown, the tilt angle β of the release tilt surface 142 relative to the vertical surface is 20–40°, and the release tilt surface 142 and the remaining surfaces of the engaging claw portion 14 are also smoothly connected by curved surfaces. Furthermore, in this embodiment, in… Figure 8 In the view shown, when a force is applied to move the plug member 100 to the left while the plug member 100 and the socket member 200 are engaged, the surface of the release inclined surface 142 contacts the second step portion 242. In other embodiments, Figure 8 In the view, the release tilt surface 142 is rotated at an angle around its left-right extending axis, with its upper edge pointing towards the center in the front-rear direction. Specifically, from the left-hand view of the plug component 100, the front release tilt surface 142 rotates counterclockwise around its left-right extending axis, and the rear release tilt surface 142 rotates clockwise around its left-right extending axis. This makes the lower edge of the release tilt surface 142 more outward in the front-rear direction relative to its upper edge. Therefore, during the release operation, only the lower edge of the release tilt surface 142 contacts the second step portion 242. Alternatively, [the following text is missing: "..."] Figure 8In the view, the release tilt surface 142 rotates at an angle around its left-right extending axis, with its upper edge moving away from the center position in the front-back direction. That is, in the left-side view of the plug component 100, the front release tilt surface 142 rotates clockwise around its left-right extending axis, and the rear release tilt surface 142 rotates counterclockwise around its left-right extending axis, so that the upper edge of the release tilt surface 142 is more outward in the front-back direction relative to the lower edge. Therefore, during the release operation, only the upper edge of the release tilt surface 142 contacts the second step portion 242.
[0084] Furthermore, the plug body 11 has a hollow structure to allow each elastic clip 13 to elastically deform inward in the front-rear direction. Preferably, as shown below... Figures 5 to 7 As shown, the plug body 11 includes a pair of plug main boards 114 arranged front to back and a plurality of reinforcing plates 115 fixed between the pair of plug main boards 114. The plug main boards 114 extend horizontally in the left-right direction and extend downward integrally from the lower end surface of the plug cover 15. The plurality of reinforcing plates 115 are spaced apart in the left-right direction and extend downward integrally from the lower end surface of the plug cover 15. The reinforcing plates 115 are perpendicular to the plug main boards 114. Each plug main board 114 has a plug opening 116 at each elastic clip 13. The elastic clip 13 extends upward integrally from the lower side of the plug opening 116 near the plug bottom 111 in a direction away from the plug bottom 111. The area between the pair of plug main boards 114 and the plug opening 116 allow the elastic clip 13 to elastically deform inward in the front-back direction.
[0085] Furthermore, such as Figures 9 to 11 As shown, the socket component 200 also includes a socket enclosure 26, which extends integrally upward from the outer edge of the socket base plate 25 toward the plug component 100. A positioning wall 22 and an anti-misinstallation protrusion 23 are fixed between the socket enclosure 26 and the socket base plate 25. The area enclosed by the socket enclosure 26, the socket base plate 25, the positioning wall 22, and the anti-misinstallation protrusion 23 forms a connecting cavity 21. Furthermore, the lower end of the positioning wall 22 extends downward to the socket base plate 25, and the upper end of the positioning wall 22 extends upward to be flush with the top of the socket enclosure 26. Four socket openings 24 are formed on the socket enclosure 26 of the socket component 200; the two front socket openings 24 and the two rear socket openings 24 are arranged facing each other, sandwiching the socket base plate 25 in the middle. Preferably, the lower end of the socket opening 24 extends downward along the insertion direction to the socket base plate 25, making the socket opening 24 an inverted U-shaped space facing the socket base plate 25, which makes it easier to achieve the engagement of the elastic clip 13 in the socket opening 24.
[0086] Preferably, the outer contour of the plug cover 15 in the plug component 100 and the outer contour of the socket enclosure 26 in the socket component 200 are consistent, both being waist-shaped extending laterally. After the plug component 100 and the socket component 200 are connected in the upright position, as... Figure 1 As shown, the plug cover 15 fits precisely on the top of the socket enclosure 26, with their outer contours aligned.
[0087] Furthermore, such as Figure 2 As shown, both the plug component 100 and the socket component 200 with the above-described structure are integrally molded parts, which can be resin parts or injection molded parts, thereby improving the structural strength of the plug component 100 and the socket component 200 respectively, and ultimately improving the engagement connection strength between the plug component 100 and the socket component 200, ensuring the connection reliability between the first connecting body and the second connecting body. In addition, the plug body 11, which is composed of the plug main board 114 and the reinforcing plate 115, has good structural strength, which also helps to improve the overall structural strength of the plug component 100. This allows the elastic clip 13 to fit well into the socket opening 24, improving the engagement connection strength between the plug component 100 and the socket component 200, and also ensuring the deformation of the elastic clip 13 in the front-back direction. In particular, the plug cover 15 forming the plug mounting portion 151 in the plug component 100 is a plate structure with good structural strength. Combined with the plug body 11 with good rigidity, it effectively avoids the twisting and deformation of the plug cover 15 when the plug component 100 is fixed with screws, improves the fixing reliability of the plug component 100, and ensures that it can be effectively and detachably connected to the socket component 200 after it is fixedly installed.
[0088] Furthermore, such as Figure 2 and Figure 4As shown, the plug member 100 has a plug bevel 113 on the left side of the plug bottom 111. The plug bevel 113 is distributed at the top of the mounting clearance area 12. That is, the plug member 100 forms the plug bevel 113 and the mounting clearance area 12 by beveling at the lower left end of the plug body 11. At the same time, the socket member 200 has a socket bevel 231 at the top of the anti-misinstallation protrusion 23. In particular, the plug bevel 113 and the socket bevel 231 have the same inclination direction, both extending inclined towards the release sliding direction and away from the bottom of the connecting cavity 21. That is, the plug bevel 113 and the socket bevel 231 both extend inclined upward to the left. When the plug member 100 and the socket member 200 are connected, the plug bevel 113 and the socket bevel 231 may just abut, or they may not contact each other, with a small gap between them. When the plug component 100 and the socket component 200 are connected in the reversed state, after the plug body 11 is inserted downwards a certain distance, the mounting positioning surface 112 on the plug body 11 abuts against the socket inclined surface 231 of the socket component 200, thereby restricting the plug body 11 from being inserted downwards into the connection cavity 21.
[0089] Furthermore, when the plug member 100 and the socket member 200 are connected, such as Figure 12 As shown, when the plug member 100 slides to the left relative to the socket member 200 along the release sliding direction, the plug inclined surface 113 will contact the socket inclined surface 231 and slide along the socket inclined surface 231. Based on the inclined setting of both the plug inclined surface 113 and the socket inclined surface 231, while the plug member 100 moves to the left relative to the socket member 200 along the release sliding direction, the plug member 100 will also move upward relative to the socket member 200 in the opposite direction to the insertion direction. This allows the plug member 100 to be disengaged from the connection cavity 21 of the socket member 200 by a certain distance in advance, making it easier to disconnect the plug member 100 from the socket member 200 and improving the disassembly of the plug member 100 when it is removed from the socket member 200.
[0090] Furthermore, at least one of the plug member 100 and the socket member 200 has a marking portion on its surface for indicating the release sliding direction. The marking portion is either a marking arrow 30 or a marking recess 40; when the marking portion is a marking arrow 30, the marking arrow 30 points in the release sliding direction. The marking portion facilitates the user's operation of the plug member 100 along the release sliding direction when releasing the engagement between the plug member 100 and the socket member 200. For example, as... Figure 6As shown, the plug component 100 has a left-facing arrow 30 on the top surface of the plug cover plate 15; as shown in Figure 8, the socket component 200 has a left-facing arrow 30 on the bottom surface of the socket base plate 25, and in addition, the socket component 200 has a marking recess 40 on the left side of the outer periphery of the socket enclosure 26.
