Description

[0002] For electrical components such as wall switches and wall sockets that need to be installed on the wall, a bottom box needs to be pre-buried in the wall so that the electrical components are fixedly assembled in the bottom box to achieve their installation on the wall.

[0076] The above drawings have shown clear embodiments of the present invention, which will be described in more detail below. These drawings and text descriptions are not intended to limit the scope of the present invention in any way, but to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0077] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0078] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more, unless otherwise clearly defined.

[0079] For electrical components such as wall switches and wall sockets that need to be installed on the wall, a bottom box needs to be pre-buried in the wall to achieve installation. The bottom box provided in the related art includes a box body and nuts located on both sides of the box body. Taking a wall switch as an example, a screw through hole is arranged on the fixing frame of the wall switch. The wall switch can be installed on the wall by passing the screw through the screw through hole and threading it with the nut in the box body.

[0080] However, the axial length of the nut is generally designed to be longer, that is, the internal thread is designed to be multiple turns, which makes it time-consuming and laborious to screw in the screw. Once the screw is slightly tilted, it not only further increases the screwing force, but may also cause damage to the nut.

[0081] In view of the above technical problems, an embodiment of the present invention provides a connecting member 100, as shown in the attached Figure 1 As shown, the connector 100 includes: a connecting portion 11, wherein the connecting portion 11 includes a connecting body 110, a first circular through hole 111 and a plurality of elastic claws 112, the first circular through hole 111 is opened on the connecting body 110, and the plurality of elastic claws 112 are arranged on the inner wall of the first circular through hole 111 at intervals around the circumferential direction.

[0082] That is to say, a plurality of elastic claws 112 are arranged in a circle around the inner wall of the first circular via hole 111 , and there is a gap between any two adjacent elastic claws 112 . Except for the positions of the elastic claws 112 in the first circular via hole 111 , the rest of the positions are vacant.

[0083] In particular, the elastic claw 112 is configured to allow the external threaded structure 300 to be inserted axially or screwed into the first circular through hole 111 circumferentially, so that the elastic claw 112 is engaged with the external thread 31 of the external threaded structure 300, and to allow the external threaded structure 300 to be screwed out of the first circular through hole 111 circumferentially. The above-mentioned axial direction refers to the direction of the central axis of the first circular through hole 111, and the above-mentioned circumferential direction refers to the direction of the circumference of the first circular through hole 111.

[0084] Exemplarily, the external threaded structural member 300 may be any component having an external thread 31 and capable of being threadedly connected with an internal threaded hole, for example, the external threaded structural member 300 may be a screw, a bolt, etc. The connector 100 provided in the embodiment of the present invention may be engaged with the external thread 31 on the external threaded structural member 300 to play a connecting role.

[0085] When connecting with the external thread structure 300, the external thread structure 300 enters the portion of the first circular through hole 111 not occupied by the elastic claws 112 by directly inserting or screwing in along the circumferential direction, so that the multiple elastic claws 112 can be meshed with a circle of external threads 31 on the external thread structure 31. When disconnecting from the external thread structure 300, the external thread structure 300 can be rotated in the reverse direction.

[0086] It can be seen that the connector 100 provided by the embodiment of the present invention not only plays the same connecting role as the internal threaded structural member, but also has more advantages than the internal threaded structural member as follows: the elastic claws 112 are arranged in only one circle, so that the structure of the connector 100 is simpler, and the connection efficiency and removal efficiency with the external threaded structural member 300 are significantly improved; the connection method with the external threaded structural member 300 is more diversified, so that the external threaded structural member 300 can be directly and quickly inserted into place, or the external threaded structural member 300 can be simply screwed in a few circles after being inserted to a certain depth, or the external threaded structural member 300 can be directly screwed in, so that the disassembly and assembly of the external threaded structural member 300 is more time-saving and labor-saving; because the elastic claws 112 have a certain elasticity, it is not only convenient for the direct insertion of the external threaded structural member 300, but also increases the adaptability to the external threaded structural member 300 in an inclined state, even if the external threaded structural member 300 is slightly tilted, it will not cause damage to the connector 100.

[0087] The connecting piece 100 provided in the embodiment of the present invention can be arranged on a base box compatible with electrical components such as wall switches and wall sockets. In this way, the external threaded structural member 300 is a screw, and the screw is connected to the connecting piece 100 to achieve the installation of the above-mentioned electrical components on the wall. It has high installation efficiency, simple and convenient installation and disassembly operations, giving users a higher experience, and also has lower costs.

[0088] The following is an exemplary description of the structure of the elastic claw 112 that realizes the above functions. Figure 2 The partial structural diagram of the connecting body 110 is shown in FIG. Figure 2 As shown, the elastic claw 112 includes: a first abutting surface 1121, a second abutting surface 1122 and a transition connecting surface 1123 connected in sequence. Figure 3 It can be known that the first abutting surface 1121 is used to abut against the upper tooth surface 311 of the thread groove 310 of the external thread structure 300 , and the second abutting surface 1122 is used to abut against the lower tooth surface 312 of the thread groove 310 .

[0089] It can be understood that, taking the external threaded structural member 300 as a screw for example, a circle of thread groove will be formed between any two adjacent circles of external threads 31 thereon, wherein the upper tooth surface 311 of the thread groove comes from the circle of external threads 31 that is closer to the head of the screw, and the lower tooth surface 312 comes from the other circle of external threads 31 that is closer to the tail of the screw.

[0090] Further, see Figure 4 It can be seen that multiple elastic claws 112 are distributed in sequence along the spiral path, and the height difference between the spiral line segment extending along the target spiral path of the second abutment surface 1122 of the elastic claw 112 at the starting end s of the spiral path and the spiral line segment extending along the target spiral path of the second abutment surface 1122 of the elastic claw 112 at the end e of the spiral path is the same as the pitch of the external threaded structural component 300; wherein, the height direction of the spiral line segment is along the axial direction of the first circular through hole 111.

[0091] See also Figure 2 The end where the second abutting surface 1122 is connected to the first abutting surface 1121 is called the first arc-shaped connecting end 1221, and the end where the second abutting surface 1122 is connected to the transition connecting surface 1123 is called the second arc-shaped connecting end 1222. The first arc-shaped connecting end 1221 and the second arc-shaped connecting end 1222 are parallel to each other.

[0092] In the direction from the first arc-shaped connecting end 1221 to the second arc-shaped connecting end 1222 , the elastic claw 112 can provide a plurality of spiral paths parallel to each other, and any one of the plurality of spiral paths can be used as the target spiral path mentioned above.

[0093] For each elastic claw 112, the second abutting surface 1122 is used to provide a spiral line segment constituting a spiral path, and for any target spiral path, it is composed of a plurality of spiral line segments on a plurality of second abutting surfaces 1122 of a plurality of elastic claws 112. In other words, the second abutting surface 1122 is an arc surface with a certain curvature, and the curvature is the same as the curvature corresponding to the spiral line segment.

[0094] It can be seen that the first arc-shaped connecting end 1221 and the second arc-shaped connecting end 1222 can both be used as the above-mentioned spiral segment. For example, there is a first height difference between the first arc-shaped connecting end 1221 of the elastic claw 112 at the starting end s of the spiral path and the second arc-shaped connecting end 1222 of the elastic claw 112 at the end e of the spiral path, and there is a second height difference between the second arc-shaped connecting end 1222 of the elastic claw 112 at the starting end s of the spiral path and the second arc-shaped connecting end 1222 of the elastic claw 112 at the end e of the spiral path. The first height difference is the same as the second height difference, and is also the same as the pitch of the external threaded structural component 300.

[0095] It can be seen that by distributing multiple elastic claws 112 in a spiral shape, the height difference between the target positioning points of the elastic claws 112 at the beginning s of the spiral path and at the end e of the spiral path is consistent with the pitch of the external threaded structural component 300, and the remaining multiple elastic claws 112 are arranged in sequence with a constant height difference, and the sum of the height differences of all elastic claws 112 is exactly one pitch. In this way, the elastic claws 112 present an arrangement similar to a single-turn internal thread structure, thereby realizing a threaded connection with the external threaded structural component 300.

[0096] Attached Figure 5 The schematic diagram of the connection relationship between the multiple elastic claws 112 and the external thread structure 300 is illustrated. The figure is a cross-sectional view in the top view direction. Figure 5 It can be seen that the heights of the plurality of elastic claws 112 decrease in sequence along the counterclockwise direction, so that this circle of elastic claws 112 is connected to a circle of external threads 31 on the external threaded structural component 300 .

[0097] As attached Figure 3 and attached Figure 4As shown, the first abutting surface 1121 is an arc-shaped surface, and the arc direction of the first abutting surface 1121 is along the inclined direction of the upper tooth surface 311 of the thread groove 310. By setting the first abutting surface 1121 as an arc-shaped surface, on the one hand, it can serve as a guide surface to guide the insertion of the external thread structure 300 into the first circular through hole 111; on the other hand, the first abutting surface 1121 abuts against the upper tooth surface 311 of the thread groove 310. Generally, the upper tooth surface 311 is an inclined plane, and setting the first abutting surface 1121 as an arc-shaped surface makes it not a completely matched surface-to-surface contact when it abuts against the upper tooth surface 311, but is more inclined to line-to-surface contact, so that it can It is adaptable to more types of external threads 31, thereby improving the adaptability of the connector 100. On the other hand, it can be considered that the arc-shaped surface gradually turns downward, and its turning-down depth progressively forms a spiral path. When the elastic claw 112 is inserted into the thread groove 310 of the external thread 31, the downward turning arc-shaped surface can provide a downward pressure on the lower tooth surface 312 of the thread groove, so that the elastic claw 112 can firmly press the external thread structure 300, thereby improving the connection stability between the connector 100 and the external thread structure 300.

[0098] In summary, it can be seen that the connector 100 provided in the embodiment of the present invention, based on the above-mentioned structural arrangement of its connecting portion 11, can replace the conventional nut to engage and connect with the externally threaded structural member 300. In particular, the externally threaded structural member 300 does not need to be screwed during installation, which not only saves the screwing time, but also can withstand the pre-tightening force during installation, thereby significantly improving the connection efficiency.

[0099] In some possible implementations, such as the attached Figure 1 As shown, the connector 100 provided in the embodiment of the present invention further includes: a first positioning portion 12 and a second positioning portion 13, which are respectively connected to different positions of the connecting body 110. The first positioning portion 12 is configured to position the connector 100 in a first direction, wherein the first direction is along the axial direction of the first circular through hole 111; the second positioning portion 13 is configured to position the connector 100 in a second direction, wherein the second direction is perpendicular to the first direction, and can also be understood as being along the radial direction of the first circular through hole 111.

[0100] By providing the first positioning portion 12 and the second positioning portion 13 , the connector 100 can be fixedly assembled in a mounting seat 200 such as a box body of a bottom box, thereby achieving effective positioning in three directions: X, Y, and Z.

[0101] The first positioning portion 12 and the second positioning portion 13 may be fixed on the mounting base 200 by self-fixation (for example, the mounting base 200 is provided with positioning holes corresponding to the positioning portions), or may be fixed by auxiliary means of fixing parts, for example, the first positioning portion 12 and the second positioning portion 13 may be fixed to the mounting base 200 by fixing parts such as screws and pins.

[0102] The embodiment of the present invention expects that the first positioning portion 12 and the second positioning portion 13 are fixed on the mounting seat 200 by a self-fixing manner, which has the advantage of simplifying the mounting structure and the mounting process.

[0103] There may be various arrangements of the first positioning portion 12 and the second positioning portion 13 in the connector 100 as long as the desired positioning can be achieved. In some examples, at least one of the first positioning portion 12 and the second positioning portion 13 is an elastic member.

[0104] By configuring one of the first positioning portion 12 and the second positioning portion 13 as an elastic member, based on the characteristics of the elastic member being able to be compressed during the assembly process and being able to stretch and reset after being assembled into place, it is convenient for the connector 100 to be simply and easily assembled to the mounting seat 200 in a self-fixing manner.

[0105] In some examples, one of the first positioning portion 12 and the second positioning portion 13 is a rigid member, and the other is an elastic member, for example, the first positioning portion 12 is a rigid member, and the second positioning portion 13 is an elastic member. By only setting one positioning portion to be elastic, on the basis of satisfying the above-mentioned installation characteristics, it is also helpful to further simplify the structure of the connector 100.

[0106] The structure of the second positioning portion 13 having elasticity is exemplarily described below. Figure 6 As shown, the second positioning portion 13 includes a relative fixed end 131 and a tilted end 132; the fixed end 131 is connected to the connecting body 110, and the tilted end 132 is tilted relative to the connecting body 110, so that the second positioning portion 13 can be deformed along the first direction.

[0107] In some examples, the height of the gap between the second positioning portion 13 and the connection body 110 gradually increases from the fixed end 131 to the tilted end 132, wherein the height of the gap is along the first direction. The fixed end 131 is used to connect the second positioning portion 13 to the connection body 110, and the tilted end 132 is used to make the second positioning portion 13 elastic, so that the tilted end 132 can compress or stretch along the axial direction (i.e., the first direction) of the first circular through hole 111.

[0108] The tilted end 132 tilts along the axial direction of the first circular through hole 111. For example, the axial direction of the first circular through hole 111 is defined as the up-down direction. The tilted end 132 may be located above the connecting body 110 (see Figure 6 ), or may be located below it (not shown in the figure).

[0109] The first positioning portion 12 can position the connector 100 in the axial direction of the first circular through hole 111 . When the first positioning portion 12 is a rigid member, the second positioning portion 13 can position the connector 100 in the radial direction of the first circular through hole 111 .

[0110] In this way, by inserting the connector 100 into the mounting seat 200 along the radial direction of the first circular through hole 111, during the insertion process of the connector 100, the tilted end 132132 of the second positioning portion 13 is compressed, and the connector 100 (including the first positioning portion 12) can be inserted without any resistance, so that the connector 100 is smoothly inserted into place. When inserted into place, the first positioning portion 12 is smoothly inserted into the corresponding positioning hole on the mounting seat 200 to achieve positioning, and the second positioning portion 13 is also moved to another corresponding positioning hole on the mounting seat 200, so that the tilted end 132 is stretched and reset to achieve positioning.

[0111] As mentioned above, the connector 100 can be installed by being inserted into the mounting seat 200, that is, the connector 100 is configured to be inserted into the mounting seat 200 to achieve the installation of the connector 100 inside the mounting seat 200. It is understandable that the connector body 110 must have a side extending along the insertion direction and an insertion start side that first enters the mounting seat 200.

[0112] The second positioning portion 13 may be located on any one of the two side portions extending along the insertion direction of the connection body 110 or on the main body portion between the two side portions, or may be located on the insertion start side of the connection body 110 .

[0113] The following is an exemplary description of the second positioning portions 13 being located at two side portions of the connecting body 110 extending along the insertion direction. This implementation method enables the connecting piece 100 to have at least the advantages of simple structure and easy molding and preparation.

[0114] As attached Figure 6As shown, the connection body 110 has a first side 101 and a second side 102 opposite to each other, and a third side 103 and a fourth side 104 opposite to each other, wherein the first side 101 and the second side 102 both extend along the insertion direction, and the third side 103 is the insertion start side of the connection body 110. The first positioning portion 12 is located on the third side 103; the number of the second positioning portions 13 is two, and the two second positioning portions 13 are located on the first side 101 and the second side 102, respectively. The distribution direction from the fixed end 131 of the second positioning portion 13 to its tilted end 132 can be parallel to the first side 101 or the second side 102 of the connection body 110 (see Figure 6 ), or may be perpendicular to the first side 101 or the second side 102 of the connecting body 110 (not shown in the figure).

[0115] In some implementations, such as the attached Figure 6 As shown, the fixed end 131 of the second positioning portion 13 faces the third side 103, and the raised end 132 of the second positioning portion 13 faces the fourth side 104, that is, the distribution direction from the fixed end 131 of the second positioning portion 13 to its raised end 132 can be parallel to the first side 101 or the second side 102 of the connecting body 110.

[0116] This method is not only conducive to reducing the width of the connector 100 (the width direction is the extension direction of the third side 103), but also facilitates the connector 100 to be manufactured through an integrated molding process. Figure 6 As shown, by stamping the first side 101 and the second side 102 of the connecting body 110, the main body part of the connecting body 110 located at the corresponding positions of the first side 101 and the second side 102 is used as the second positioning portion 13. After the second positioning portion 13 is tilted, a groove 113 is formed at the corresponding position on the connecting body 110.

[0117] In some examples, the first positioning portion 12 and the second positioning portion 13 are respectively located on both sides of the first circular via 111. The embodiment of the present invention expects that the connector 100 is manufactured by an integrated molding process. For example, the connector 100 can be made of high-hardness metal (such as stainless steel) or high-strength plastic.

[0118] By designing the connector 100 as an integrally formed structural component, the connector 100 has a simple structure, a stronger structural stability, and is easy to prepare.

[0119] On the other hand, an embodiment of the present invention further provides a mounting device, which includes a mounting seat 200 and any one of the above-mentioned connecting members 100; Figure 7As shown, the mounting seat 200 includes a mounting body 20 and a bearing portion 21 . The mounting body 20 has a first accommodating cavity 201 inside. The bearing portion 21 is located in the first accommodating cavity 201 . The bearing portion 21 is configured to be able to bear and fix the connector 100 .

[0120] The mounting device provided in the embodiment of the present invention can be any mechanical structural component that needs to be connected to the external thread structural component 300, for example, Figure 7 The example installation device is a bottom box, which is suitable for the installation and fixation of a wall switch and a wall socket.

[0121] The installation device includes a mounting seat 200 to support the connector 100, wherein the mounting seat 200 includes a bearing portion 21 to support the connector 100; the first accommodating cavity 201 of the installation body portion 20 is not only used to accommodate the bearing portion 21, but also used to accommodate external devices, such as a wall switch, a wall socket, etc. In this way, the external threaded member passes through the external device and the connector 100 at the same time, and is connected to the connector 100, so that the external device can be fixed inside the installation device.

[0122] The installation method of the connecting member 100 on the bearing part 21 can be a self-fixing method, and can also be assisted by fixing members. For the self-fixing method, the connecting member 100 includes: a connecting part 11, and a first positioning part 12 and a second positioning part 13 connected to the connecting part 11. According to the structure of the first positioning part 12 and the second positioning part 13 and their positions on the connecting part 11, the structure of the bearing part 21 is adaptively designed, so that the bearing part 21 has corresponding accommodating structures corresponding to the connecting part 11, the first positioning part 12 and the second positioning part 13.

[0123] The following only illustrates the assembly method of the bearing portion 21 and the connecting member 100 by way of self-fixation: Figure 7 And attached Figure 8 As shown, an insertion hole 202 is provided on the wall of the mounting body 20 ; the bearing portion 21 includes: a bearing shell 211 , a second accommodating cavity 212 , a second circular through hole 213 , a first positioning hole 214 , and a second positioning hole 215 .

[0124] The second accommodating cavity 212 is formed inside the carrying shell 211 and communicates with the insertion hole 202 ; the second circular through hole 213 , the first positioning hole 214 , and the second positioning hole 215 are respectively located at different positions on the carrying shell 211 , and are each communicated with the second accommodating cavity 212 .

[0125] The bearing portion 21 is configured to allow the connector 100 to be inserted into the second accommodating cavity 212 through the insertion hole 202, so that the first circular through hole 111 on the connecting portion 11 is connected to the second circular through hole 213, and the first positioning portion 12 is positioned in the first positioning hole 214, and the second positioning portion 13 is positioned in the second positioning hole 215. The second circular through hole 213 penetrates the bearing housing 211 along the first direction, and is connected to the first circular through hole 111 when the connector 100 is installed, so as to accommodate the external threaded structural member 300.

[0126] As described above, the structure of the bearing portion 21 is adaptively designed according to the structures of the first positioning portion 12 and the second positioning portion 13 and their positions on the connecting portion 11 .

[0127] In some examples, such as the attached Figure 6 As shown, the first positioning portion 12 is located at the third side 103; there are two second positioning portions 13, which are respectively located at the first side 101 and the second side 102. The fixed end 131 of the second positioning portion 13 faces the third side 103, and the raised end of the second positioning portion 13 faces the fourth side 104.

[0128] Accordingly, as attached Figure 8 As shown, the bearing portion 21 includes a first shell wall 2101, a second shell wall 2102 and a third shell wall 2103 which are connected vertically in sequence from head to tail, and the second shell wall 2102 is also opposite to the insertion hole 202. The second circular through hole 213 includes: a first through hole section 2131 and a second through hole section 2132 which are arranged oppositely and connected coaxially; the second positioning hole 215 and the first through hole section 2131 are formed at different positions on the first shell wall 2101; the first positioning hole 214 is formed on the second shell wall 2102; the second through hole section 2132 is formed on the third shell wall 2103, the second through hole section 2132 is used to accommodate a plurality of elastic claws 112 of the connecting portion 11, and the third shell wall 2103 is used to abut against the connecting body 110 of the connecting portion 11.

[0129] The diameter of the second through hole section 2132 can be larger than the diameter of the first through hole section 2131. For example, the diameter of the first through hole section 2131 is adapted to the diameter of the external thread structure 300, and the two can be transitionally matched. The second through hole section 2132 needs to increase the radial dimension of the elastic claw 112 compared to the first through hole section 2131. When used, the external thread structure 300 is inserted through the first through hole section 2131, the first circular through hole 111, and the second circular through hole 213 in sequence and connected to the connector 100.

[0130] Attached Fig. 9 Example Figure 8Schematic diagram of the connection relationship between the load-bearing portion 21 and the first positioning portion 12 of the connecting member 100, the connecting member 100 is inserted from the insertion hole 202 into the second accommodating cavity 212 of the load-bearing portion 21 along the second direction. During the insertion process, the second positioning portion 13 is compressed downward, and finally the first positioning portion 12 of the connecting member 100 is inserted into the first positioning hole 214 along the second direction. In this way, the first positioning portion 12 will not be able to move along the first direction, thereby realizing the positioning of the connecting member 100 in the first direction.

[0131] Attached Fig.10 Example Figure 8 Schematic diagram of the connection relationship between the bearing portion 21 and the second positioning portion 13 of the connecting member 100. During the insertion of the connecting member 100 along the second direction, the second positioning portion 13 is compressed downward. When the second positioning portion 13 moves with the connecting member 100 to be opposite to the second positioning hole 215, the second positioning portion 13 stretches and resets, and the raised end of the second positioning portion 13 is inserted into the second positioning hole 215. Fig.10 It can be known that the second positioning hole 215 positions the tilted end of the second positioning portion 13 in the second direction, so that the second positioning portion 13 cannot move along the second direction, thereby achieving the positioning of the connector 100 in the second direction.

[0132] When the connecting member 100 is positioned inside the second accommodating cavity 212 , the connecting body 110 of the connecting member 100 overlaps the third shell wall 2103 of the bearing portion 21 , further improving the installation stability of the connecting member 100 inside the second accommodating cavity 212 .

[0133] The structures of the first positioning hole 214 and the second positioning hole 215 are adaptively designed according to the shapes of the raised ends of the first positioning portion 12 and the second positioning portion 13, see Figure 7-10 The first positioning hole 214 and the second positioning hole 215 are both designed as rectangular holes. In addition, the above-mentioned assembly method of the bearing portion 21 and the connecting member 100 makes it easy to disassemble the connecting member 100. When the connecting member 100 needs to be disassembled, it is only necessary to press the raised end of the second positioning portion 13 from the second positioning hole 215 until it is disengaged, so that the connecting member 100 can be ejected to the second accommodating cavity 212.

[0134] It can be seen that the connecting member 100 is detachably assembled in the bearing portion 21 , so that the connecting member 100 is easy to replace. Once the connecting member 100 is damaged or does not match the external threaded structural member 300 , it only needs to be replaced with a new connecting member 100 .

[0135] In some examples, the second accommodating cavity 212, the second circular through hole 213, the first positioning hole 214 and the second positioning hole 215 are all designed with a movable margin; the movable margin is configured to enable the connector 100 to move in a direction perpendicular to the axial direction of the second circular through hole 213, so that the central axis of the first circular through hole 111 of the connector 100 coincides with the central axis of the external threaded structural component 300.

[0136] By designing the above-mentioned movable margin, not only will the positioning effect of the bearing portion 21 on the connecting member 100 not be affected, but after the connecting member 100 enters the second accommodating cavity 212, it can be adjusted left and right along the second direction to adapt to the tilted placement and violent installation of the external threaded structural member 300. In addition, the elastic characteristics of the elastic claws 112 make it difficult for the connecting member 100 to be damaged.

[0137] The arrangement position of the connector 100 in the mounting seat 200 can be of various types, and can be adaptively arranged according to the specific requirements of the mounting seat 200. In some examples, such as the attached Fig.11 As described above, the connectors 100 are arranged in two groups, and the two groups of connectors 100 are symmetrically arranged in the mounting seat 200. That is, two groups of bearing parts 21 are symmetrically arranged in the mounting seat 200, and each group of bearing parts 21 correspondingly carries one group of connectors 100.

[0138] Each group of connecting members 100 may include one, two, three or more connecting members 100 . Accordingly, each group of carrying portions 21 may include one, two, three or more carrying portions 21 .

[0139] For some examples, see Fig.11 and Fig.12 The installation device is a bottom box buried in the wall, suitable for wall switches, wall sockets, wall interfaces or wall footlights. Fig.10 Only the structure of the bottom box is shown as an example. Fig.12 The assembly relationship between the base box and the wall socket is illustrated.

[0140] The above description is only for the purpose of facilitating those skilled in the art to understand the technical solution of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
