[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0043] In the description of the present application, “plurality” means two or more, unless otherwise clearly defined.

[0044] In order to solve the technical problems in the prior art that it is difficult to disassemble one of the assembled multiple circuit boards separately, and that such circuit boards are large in length and width and require more installation area in the equipment.

[0045] The following describes in detail the specific structure of an interface component provided by the embodiment of the present invention. Figure 1 and 6 The specific structure shown,

[0046] The interface assembly includes an interface seat 1 and a plug connector 2; the interface seat 1 is provided with a plurality of connecting through holes 11, and the connecting through holes 11 are arranged in a matrix in one row or multiple rows; each row of connecting through holes 11 is composed of at least two connecting through holes 11; an electrical connecting piece 12 is fixedly arranged in the connecting through hole 11, and the electrical connecting piece 12 is a cylindrical connecting piece obtained by curling a metal sheet; the outer side surface of the interface seat 1 is provided with a snap-fit protrusion 13; the plug connector 2 is provided with a plug post 21 that matches the shape of the connecting through hole 11, and each of the plug posts 21 is provided with a plug pin 22; the side of the plug connector 2 is provided with a limiting piece 23 that is adapted to the locking protrusion 13; when the plug connector 2 is plugged into the interface seat 1, the locking protrusion 13 is engaged with the limiting piece 23 and the plug pin 22 is plugged into the electrical connecting piece 12.

[0047] During specific application, the plug connector 2 can be plugged and fixed on the interface seat 1. By pressing the plug connector 2 downward, the limit piece 23 set on the side of the plug connector 2 is engaged with the engaging protrusion 13, so that the plug connector 2 can be firmly connected to the interface seat 1, and the vibration generated during the operation of the elevator is prevented from loosening the plug connector 2; when the plug connector 2 is pressed downward, the plug post 21 is embedded in the connecting through hole 11 of matching shape, and the plug connector 2 is further pressed downward, so that the plug pin 22 is embedded in the through hole in the center of the electrical connection piece 12. Since the plug post 21 matches the shape of the connecting through hole 11, the plug connector 2 can be limited by the matching relationship between the interface seat and the connecting through hole 11, so as to prevent the plug pin 22 in the plug connector 2 from being unable to accurately insert into the through hole in the center of the electrical connection piece 12. Because the electrical connection piece 12 is a cylindrical connection piece formed by curling a metal sheet, the electrical connection piece 12 itself has a certain degree of elasticity. When the plug pin 22 is inserted into the through hole in the center of the electrical connection piece 12, the plug pin 22 squeezes the electrical connection piece 12, causing the electrical connection piece 12 to slightly deform. Based on this deformation, the electrical connection piece 12 generates an elastic force and tightly wraps around the plug pin 22, thereby establishing a tight electrical connection between the plug pin 22 and the electrical connection piece 12. Even if the electrical connection piece 12 vibrates slightly, it can rely on its own elastic force to maintain the electrical connection with the plug pin 22, thereby preventing vibration during elevator operation from affecting the reliability of the electrical connection between the electrical connection piece 12 and the plug pin 22. In order to ensure that the electrical connection piece 12 has good elasticity, the number of turns of the electrical connection piece 12 is greater than 1. In a preferred embodiment, the number of turns of the electrical connection piece 12 is 1.25-2.

[0048] In a more specific embodiment, the two connecting through holes 11 at both ends of a row of connecting through holes 11 on the interface seat 1 are horseshoe-shaped through holes 111, and the straight sides of the two horseshoe-shaped through holes 111 face the same direction, and the other connecting through holes 11 set on the interface seat 1 are all circular through holes 112.

[0049] Furthermore, in order to prevent the plug connector 2 from being unable to be accurately plugged into the interface seat 1, the shape of the connecting through hole 11 on the interface seat 1 can be set to be a horseshoe-shaped through hole 111, such as Figure 2 and Figure 4 As shown, the plug connector 2 is provided with a corresponding plug post 21 that matches the horseshoe-shaped through hole 111. Among them, the connecting through hole 11 includes a horseshoe-shaped through hole 111 and a circular through hole 112. The cross section of the horseshoe-shaped through hole 111 is formed by a combination of a rectangle and a semicircle. If only one row (or one column) of connecting through holes 11 is provided on the interface seat 1, then the two connecting through holes 11 at both ends of the row of connecting through holes 11 can be horseshoe-shaped through holes 111, and the straight edges of the two horseshoe-shaped through holes 111 face the same direction, and the other connecting through holes 11 are circular through holes 112. The specific structure is as follows Figure 8By providing the horseshoe-shaped through hole 111, the plug connector 2 can be smoothly inserted into the interface seat 1 only in a certain orientation, thereby preventing the plug connector 2 from being inserted into the interface seat 1 in any orientation, thereby preventing the electrical connection relationship from being incorrect.

[0050] More specifically, the interface seat 1 is provided with multiple rows of connecting through holes 11; and each row of connecting through holes 11 is composed of three connecting through holes 11 arranged in an arrangement; a row of connecting through holes 11 in which two connecting through holes 11 are horseshoe-shaped through holes 111 is arranged close to the first side; a connecting through hole 11 in the center of a row of connecting through holes 11 arranged close to the second side on the interface seat 1 is a horseshoe-shaped through hole 111; the second side is the other side opposite to the first side; the straight sides of the horseshoe-shaped through holes 111 in the row of connecting through holes 11 close to the second side are opposite to the straight sides of the horseshoe-shaped through holes 111 arranged close to the second side.

[0051] Further, such as Figure 3 and Figure 9 As shown, if the interface socket 1 is provided with multiple rows of connecting through holes 11, in addition to the two connecting through holes 11 at both ends of the row of connecting through holes 11 near the first side being horseshoe-shaped through holes 111, a connecting through hole 11 in the center of the row of connecting through holes 11 near the second side can also be provided as a horseshoe-shaped through hole 111, with the first side and the second side facing each other. The straight edges of the horseshoe-shaped through holes 111 in the two rows of connecting through holes 11 face away from each other. This arrangement prevents the plug connector 2 from being inserted into the interface socket 1 in any orientation, which could lead to an incorrect electrical connection.

[0052] in, Figure 8 This is only an example of setting a row (or column) of connecting through holes 11 on the interface seat 1. In actual application, any number of connecting through holes 11 of not less than 2 can be set in a row (or column) of connecting through holes 11, such as setting the number of connecting through holes 11 in a row to 6 or 8. Figure 3 and 9 This is merely an example of providing multiple rows of connection through holes 11 on the interface seat 1 . In actual application, any number of rows of connection through holes 11 can be provided, such as 4 rows of connection through holes 11 or 6 rows of connection through holes 11 on one interface seat 1 .

[0053] In a more specific embodiment, a locking protrusion 13 is provided on two opposing side surfaces of the interface base 1, and a limiting member 23 is provided on two opposing sides of the plug connector 2. Specifically, the top of the locking protrusion 13 is flush with the top surface of the interface base 1, and the outer side of the locking protrusion 13 away from the interface base 1 is a downwardly inclined surface. The limiting member 23 includes a first limiting block 231 and a second limiting block 232 that are oppositely disposed. The first limiting block 231 and the second limiting block 232 are both disposed in grooves provided on the side walls of the plug connector 2. When the plug connector 2 is plugged into the interface base 1, the first limiting block 231 and the second limiting block 232 slide along the inclined surface of the locking protrusion 13 into the lower side of the locking protrusion 13, thereby fixing the plug connector 2 in engagement with the interface base.

[0054] A locking protrusion 13 can be provided on two opposite sides of the interface seat, and a limiting member 23 is provided on two opposite sides of the plug connector 2. The number and position of the limiting members 23 correspond to the locking protrusions 13.

[0055] Specifically, the top of the engaging protrusion 13 is flush with the top surface of the interface seat 1, and the outer side surface of the engaging protrusion 13 away from the interface seat 1 is a downwardly inclined surface. The specific setting structure is as follows: Figure 2 and Figure 4 As shown. The limiting member 23 includes a first limiting block 231 and a second limiting block 232, and the two limiting blocks are arranged opposite to each other. The side wall of the plug connector 2 is provided with a groove, and the two limiting blocks are both arranged in the groove. The specific setting structure is as shown Figure 5 and Figure 6 When the plug connector 2 is plugged into the interface seat 1, the first limit block 231 and the second limit block 232 slide downward along the inclined surface into the lower side of the engaging protrusion 13, so that the plug connector 2 is fixedly engaged with the interface seat; the combined structure of the limit member 23 and the engaging protrusion 13 is shown in FIG. Figure 7 shown.

[0056] In a more specific embodiment, the top angle of the first limit block 231 facing the second limit block 232 is set to a circular arc-shaped top angle, and the top angle of the second limit block 232 facing the first limit block 231 is set to a circular arc-shaped top angle. The limit member 23 further includes a limit baffle 233, which is arranged above the first limit block 231 and the second limit block 232; the side of the limit baffle 233 facing the engaging protrusion 13 is adapted to the inclined surface of the engaging protrusion 13. Furthermore, a protrusion 131 is provided at the bottom of the engaging protrusion 13, and the protrusion 131 and the bottom side of the engaging protrusion 13 are combined to form an L-shaped boss. The first limit block 231 and the second limit block 232 slide into one side of the L-shaped boss to engage.

[0057] Furthermore, in order to facilitate the first limit block 231 and the second limit block 232 to slide smoothly into the lower side of the engaging protrusion 13, the top angle of the first limit block 231 can be set to a circular arc top angle, and the top angle of the second limit block 232 can be set to a circular arc top angle. The specific setting structure is as follows: Figure 7 By setting the arc-shaped top angle for transition, the first limit block 231 and the second limit block 232 can slide more smoothly into the lower side of the engaging protrusion 13, thereby improving the smoothness of the engaging connection between the plug connector 2 and the interface seat 1.

[0058] Furthermore, in order to improve the stability of the engagement between the limiting member 23 and the engaging protrusion 13, a limiting baffle 233 can be provided. The limiting baffle 233 is provided above the first limiting block 231 and the second limiting block 232, and the inner side surface of the limiting baffle 233 is adapted to the inclined surface of the engaging protrusion 13. The specific setting structure is as follows: Figure 7 As shown, when the plug connector 2 slides downward along the interface base 1, the limiting baffle 233 cooperates with the inclined surface of the engaging protrusion 13, thereby limiting and guiding the sliding direction of the plug connector 2, improving the smoothness of the engagement between the limiting member 23 and the engaging protrusion 13; and after the limiting member 23 is engaged and fixed with the engaging protrusion 13, the limiting baffle 233 can limit the plug connector 2 and prevent the plug connector 2 from lateral translation, thereby improving the stability of the connection between the plug connector 2 and the interface base 1, that is, further improving the stability of the electrical connection between the electrical connection piece 12 and the plug pin 22.

[0059] Furthermore, a protruding block 131 may be provided at the bottom of the engaging protrusion 13, and the protruding block 131 and the bottom side surface of the engaging protrusion 13 are combined to form an L-shaped boss. The specific structure is as follows: Figure 2 、 Figure 4 and Figure 7 The protruding block 131 can abut against the first limiting block 231 and the second limiting block 232, thereby limiting the plug connector 2 and preventing the plug connector 2 from lateral translation, further improving the stability of the connection between the plug connector 2 and the interface seat 1.

[0060] In a more specific embodiment, the side of the interface seat 1 where the locking protrusion 13 is not provided is also provided with a bottom protrusion, and the bottom protrusions are arranged at equal intervals on the side of the interface seat 1, and the bottom protrusions are provided between adjacent connecting holes 11 or at the top corners of the interface seat 1.

[0061] Furthermore, a bottom protrusion can be provided on the side of the interface seat 1 where the engaging protrusion 13 is not provided. The arrangement structure of the bottom protrusion is as follows: Figure 2 、 Figure 3 、 Figure 8 and Figure 9As shown. The bottom protrusions can be arranged at equal intervals on the side of the interface seat, and the bottom protrusions can be set at a position between adjacent connecting through holes 11, or the bottom protrusions can be set at the top corners of the interface seat 1. The bottom protrusions can be used to mark the assembly position of the interface seat 1 to avoid the inability to accurately identify the orientation of the interface seat 1 when it is assembled on the control board. At the same time, since the setting position of the bottom protrusion matches the setting position of the connecting through hole 11, when the plug connector 2 is plugged into the interface seat 1, the bottom protrusion can also be used to identify the setting number and setting position of the connecting through hole 11 on the interface seat. For example, the setting number of rows (or setting number of columns) of the connecting through holes 11 can be accurately determined by the setting number of the bottom protrusions, and the center of the connecting through hole 11 can be accurately determined by the center point of the connecting line of adjacent bottom protrusions, that is, the setting number and setting position of the connecting through hole 11 can be accurately identified.

A printed circuit is provided within the control panel, and an electrical connection terminal of the printed circuit is electrically connected to an electrical connection plate within the interface socket, such as by soldering or other methods.
