Description

Technical Field

[0001] The utility model relates to the field of wiring terminals, in particular to a wiring terminal and an electronic device thereof. Background Art

[0002] At present, many electrical equipment and electronic equipment in certain fields, such as IoT controllers, IoT DTUs (Data Transfer Units), digital bases (Digital Infrastructure, DI), PLCs (Programmable Logic Controllers), etc., hereinafter referred to as electronic equipment, are mostly fixed on the guide rails of the control cabinet in a back-hanging manner. The guide rails are mostly arranged horizontally. The wiring end faces on the electronic equipment housings are located on the front side of the housing (opposite to the back side) or on the top and bottom sides of the housing. The wiring ports on the wiring end faces are all extended horizontally to accommodate the wiring ports of multiple wiring terminals arranged linearly. The extension direction of the wiring ports is parallel to the guide rails. The wiring ports are used to electrically connect to the ends of the cables to achieve electrical connection between the cables and the electronic equipment. Since the spring-type wiring terminals enable the cables (the wires therein) to be self-locking after being inserted into the wiring ports of the wiring terminals, multiple spring-type wiring terminals are currently arranged linearly to form multiple wiring ports.

[0003] Since the extension direction of the connection port (on the housing) of this type of electronic equipment is parallel to the guide rail, the number of electronic equipment connection terminals (or connection ports) accommodated is limited without increasing the length of the guide rail, which also limits the function of the electronic equipment to some extent.

[0004] Therefore, it is necessary to develop an electronic device and a corresponding terminal block that can provide more wiring ports without increasing the length of the guide rail. Utility Model Content

DETAILED DESCRIPTION

[0033] The following is a detailed description of embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0034] References to "one embodiment" or "an example" or "an example" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment disclosed in the present utility model. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0035] The circuit boards of conventional electrical or electronic equipment are all arranged horizontally. When connecting the wiring terminals, the conductive connectors of the wiring terminals are inserted vertically downward and perpendicular to the surface of the circuit board into the corresponding mounting ports on the circuit board for connection. When there are multiple wiring terminals, they are also arranged linearly along the surface of the circuit board.

[0036] For example, in Figure 1 A schematic diagram of the structure of an electronic device arranged horizontally is shown in FIG. 1 , specifically, a schematic diagram of the structure of a controller. In the figure, a circuit board 120 is arranged horizontally in a housing 110 of an electrical device or an electronic device (the structure of fixing the circuit board 120 in the housing 110 is ignored), the thickness direction of the circuit board 120 is the z-axis direction in the figure, and the circuit board 120 has a length and a width, which correspond to the y-axis (not shown in the figure) and the x-axis respectively. In a rectangular coordinate system formed by the x-axis, the y-axis and the z-axis, the y-axis is perpendicular to the x-axis and the y-axis respectively. The figure is a front view of the Internet of Things control terminal along the y-axis direction.

[0037] In the figure, in the x-axis direction (i.e., the width direction of the circuit board 120), the connection terminal is arranged on the upper surface of one side edge of the circuit board 120. The conductive connector 250 of the connection terminal is vertically downward and perpendicular to the surface of the circuit board 120 and inserted into the corresponding mounting opening on the circuit board 120 for connection. The connection terminal is connected to the wire 300 at a side away from the circuit board 120 in the horizontal direction, and the connection direction of the wire 300 and the connection terminal is parallel to the circuit board 120.

[0038] In order to facilitate later maintenance, repair or replacement, the connection terminal and the wire 300 are connected in a detachable manner. At the same time, in order to quickly disassemble and assemble, the connection terminal is mostly a spring-type, and the wire connected to the connection terminal is provided with a limiting portion 310 (such as a limiting protrusion or a limiting groove) on the surface of its end, which can be stuck by the spring inside the connection terminal after being inserted into the connection terminal, or the limiting portion 310 is locked by the spring to prevent the wire from being detached. In addition, an adjustment hole 230 is provided on the connection terminal for a tool to extend into and operate the spring to remove the wire.

[0039] Usually, the opening direction of the adjustment hole 230 and the opening direction of the wiring hole are almost parallel to the circuit board, and the opening direction of the adjustment hole 230 is in the same direction as the opening direction of the wiring hole. The wire is connected to the wiring hole along the opening direction of the wiring hole. The wiring hole is closer to the circuit board than the adjustment hole, that is, the adjustment hole is located at the outermost side. Multiple wiring terminals are arranged in a straight line along the y-axis direction (that is, the length direction of the circuit board 120), that is, as the number of wiring terminals increases, more length of the guide rail will be occupied accordingly.

[0040] In some cases, for example, to reduce the installation length of the guide rails in the control cabinet occupied by such electronic equipment, the inventors have designed electronic equipment with wiring ports extending vertically (i.e., the back side points to the front side) on the wiring end face (i.e., the wiring ports are arranged vertically). The circuit board 120 of such electronic equipment is arranged vertically, i.e., the surface where the circuit board is located is nearly perpendicular to the installation surface of the control cabinet. When multiple wiring terminals are installed on the surface of the circuit board 120, they are arranged from the back side of the housing to the front side. Specifically, the arrangement direction of the wiring ports is as follows: Figure 2 As shown in the direction of the middle arrow, the back of the housing 110 has a slot 130 for connecting to the guide rail in the control cabinet. The slot 130 is arranged horizontally, and the direction of the slot arrangement is almost perpendicular to the arrangement direction of the wiring ports. At this time, if the above-mentioned existing wiring terminal structure is continued to be used, either the cable is perpendicular to the surface of the circuit board 120, which will increase the bending angle when multiple cables are subsequently bundled.

[0041] To this end, as the first aspect of the utility model, a wiring terminal is provided that can be applied to an electronic device with a vertically arranged wiring port. The electronic devices here are such as an Internet of Things controller, an Internet of Things DTU (Data Transfer Unit), a digital base (Digital Infrastructure, DI), a PLC (Programmable Logic Controller), etc., and can also be a logic control circuit formed by combining the mechanical contacts of each electrical component in series or parallel without limitation.

[0042] like Figure 3 , Figure 4 and Figure 5 As shown, the wiring electronic device includes a housing 200, a conductive connector 250 and an elastic member 260. The housing 200 has a mounting cavity 210, and is provided with a wiring port 220 and an adjustment hole 230 respectively connected to the mounting cavity 210. The wiring port 220 is used to insert the wire 300, the mounting cavity 210 is located at the end of the wiring port 220, and the adjustment hole 230 is connected to the mounting cavity 210 from the side. The mounting cavity 210, the adjustment hole 230 and the wiring port 220 extend from the outside of the housing to the inside of the housing in three directions respectively and meet and connect in the middle area of ​​the housing.

[0043] When the wire 300 is inserted into the mounting cavity 210 through the connection port 220 , the portion of the wire 300 inserted into the mounting cavity 210 can be electrically connected to the conductive connector 250 located in the mounting cavity.

[0044] The housing 200 has a mounting end face 240, which is the outer wall of the housing 200 at the end of the extension direction of the mounting cavity 210. One end of the conductive connector 250 passes through the mounting end face 240, and the other end of the conductive connector 250 extends into the mounting cavity 210 and extends toward the wiring port.

[0045] When the terminal block in this embodiment is connected to an electronic device, the mounting end face 240 is used to dock (fit) with the surface of the circuit board 120 in the electronic device. The circuit board 120 of the docking device is provided with a socket, which corresponds to the conductive connector 250. The protruding portion of the conductive connector 250 can be inserted into the corresponding socket on the circuit board and then fixed by welding. The surface where the outer port of the adjustment hole 230 is located is located between the mounting end face 240 and the surface where the outer port of the wiring port 220 is located. The surface where the outer port of the adjustment hole 230 is located, the mounting end face 240, and the surface where the outer port of the wiring port 220 is located are oriented differently from each other.

[0046] The elastic member 260 is located in the installation cavity 210 and is used to electrically connect the wire 300 to the other end of the conductive connector 250. Since the positions and angles of the installation cavity, the wiring port and the adjustment hole of the wiring terminal in this embodiment are changed compared to the existing spring-type wiring terminal, the installation position, angle and structure of the elastic member 260 are also improved accordingly.

[0047] Specifically, a mounting structure is provided between the conductive joint 250 and the adjustment hole, and the mounting structure can fix one end of the elastic member 260 and limit the elastic member 260 after the elastic member 260 is bent and deformed to a preset degree.

[0048] When the wire is not inserted from the wiring port, the other end of the elastic member 260 is located deep in the adjustment hole and can abut against the end of the conductive connector 250 located near the wiring port. At this time, the elastic member 260 is in an undeformed or slightly deformed state, and the abutment between the other end of the elastic member 260 and the conductive connector 250 can be direct contact or there can be a certain gap, but the spacing of the gap must be smaller than the diameter of the wire. In this way, when the wire is inserted from the wiring port between the other end of the elastic member 260 and the conductive connector 250, the elastic member 260 can be bent and deformed, so that the other end of the elastic member 260 can be tightly abutted against the limiting portion 310 located on the outer wall of the wire after deformation. The limiting portion 310 can be a limiting protrusion or a limiting groove set on the surface of the wire at its end. When the wire is dragged by an external force, the other end of the elastic member 260 can clamp the limiting portion 310 and prevent the wire from detaching from the wiring port.

[0049] The outer end of the adjustment hole 230 is on the surface of the housing 200, and the inner end of the adjustment hole 230 is on the side wall of the installation cavity 210. Since the other end of the elastic member 260 is arranged deep in the adjustment hole and opposite to the inner end of the adjustment hole 230, it is convenient to use a tool to extend from the adjustment hole to operate the other end of the elastic member 260 during disassembly, that is, to apply a suitable force to the other end of the elastic member 260, so that it can be slightly deformed, and the limiting part 310 of the wire can be allowed to move along the axial direction of the wire, thereby releasing the restriction on the wire and facilitating the removal of the wire.

[0050] In this embodiment, the wiring terminal, on the one hand, readjusts the position and angle of the conductive joint 250, the wiring port and the adjustment hole to adapt to the electronic device with the wiring port arranged vertically; on the other hand, the internal space of the wiring terminal housing and the elastic member 260 are improved at the same time, so that the setting mode of the elastic member 260 can adapt to the wiring port and the adjustment hole after the position and angle are readjusted, so that it is possible to provide electronic devices with more wiring ports without increasing the length of the guide rail. The following will describe these two aspects in combination with some embodiments.

[0051] In some embodiments, the conductive connector 250 generally extends outward perpendicular to the mounting end face 240, and the angle (error) between the two is allowed to be within a range of ±10°, that is, the mounting end face 240 is usually parallel to the normal plane corresponding to the conductive connector 250, and the angle between the mounting end face 240 and the normal plane of the conductive connector is 80°-90°. Similarly, the extension direction of the outer port of the adjustment hole 230 is usually perpendicular to the surface on which it is located, that is, the surface on which the outer port of the adjustment hole 230 is located is parallel to the normal plane corresponding to the extension direction of the outer port of the adjustment hole 230. The extension direction of the outer port of the wiring port 220 is usually perpendicular to the surface on which it is located, that is, the surface on which the outer port of the wiring port 220 is located is parallel to the normal plane corresponding to the extension direction of the outer port.

[0052] However, for the convenience of manufacturing or aesthetics, the surface where the outer port of the adjustment hole 230 is located, the surface where the outer port of the wiring port 220 is located, or the mounting end surface 240 can be designed to be an arc surface or a curved surface or other discontinuous surfaces, such as a stepped multi-section step surface. In this case, the surface where the outer port of the adjustment hole 230 is located, the surface where the outer port of the wiring port 220 is located, or the mounting end surface 240 is not easy to define, and the normal plane corresponding to the extension direction of the outer port of the adjustment hole 230 can also be regarded as the surface where the outer port of the adjustment hole 230 is located. Similarly, the normal plane corresponding to the extension direction of the outer port of the wiring port 220 can also be regarded as the surface where the outer port of the wiring port 220 is located, or the normal plane corresponding to the direction of the conductive connector 250 can be regarded as the mounting end surface 240.

[0053] In addition, one or more continuous transition surfaces (plane, arc or curved surface) can be set between the mounting end surface 240 and the surface where the adjustment hole 230 is located, and between the surface where the adjustment hole 230 is located and the surface where the wiring port 220 is located to connect the two, and there is no limitation here.

[0054] Furthermore, the portion of the conductive connector 250 exposed from the mounting end surface 240, the axial direction (i.e., the extension direction) of the adjustment hole 230, and the axial direction (i.e., the extension direction) of the wiring port 220 are all in the same plane. Figure 3 The plane formed by the YZ axis is parallel to the plane formed by the YZ axis. The plane is divided by the conductive connector 250, and the adjustment hole 230 and the wiring port 220 are located on the same side of the plane. Here, the same plane where the three are located usually refers to the plane where the axes of the three are located, or the plane that passes through the conductive connector 250, the outer port of the adjustment hole 230 and the outer port of the wiring port 220 at the same time. In other words, the projections of the three in a certain direction partially overlap, so that the three can pass through the same plane.

[0055] In this way, relative to the installation object of the terminal block (i.e., the circuit board 120), the installation end surface 240 where the conductive connector 250 is located faces inward (the surface facing the circuit board 120), and the surface where the external port of the wiring port 220 is located faces outward, while the surface where the external port of the adjustment hole 230 is located is located between the two and the two ends are connected to the two respectively. That is, when the terminal block is inserted into an electronic device with a vertically arranged wiring port, the surface where the external port of the adjustment hole 230 is located and the surface where the external port of the wiring port 220 is located can face the left and right sides of the circuit board 120 respectively, which is convenient for later maintenance and disassembly.

[0056] Specifically, Figure 3 As shown, relative to the direction in which the conductive connector 250 passes through the mounting end surface 240 and the extension direction of the outer port of the connection port 220 The extension direction of the outer end of the adjustment hole 230 It is more inclined to the side close to the conductive joint 250. That is, in the figure, ∠AOB is smaller than ∠BOC, where O is the intersection area of ​​the installation cavity, the adjustment hole and the wiring port in the housing near the center, not a specific point.

[0057] Optionally, the direction in which the conductive connector 250 passes through the mounting end surface 240 is The extension direction of the outer end of the adjustment hole 230 The angle between them is an acute angle, that is, ∠AOB is an acute angle. Preferably, ∠AOB is between 20° and 70°.

[0058] The direction in which the conductive connector 250 passes through the mounting end surface 240 and the extension direction of the outer port of the connection port 220 The angle between them is an obtuse angle, that is, ∠AOC is an obtuse angle.

[0059] In a preferred embodiment, ∠BOC is between 70° and 110°, preferably a right angle.

[0060] For example, ∠AOB is 45°, ∠AOC is 135°, that is, ∠BOC is a right angle.

[0061] In one embodiment, the conductive connector 250 is in a sheet shape and has a width and a thickness. Figure 2 and Figure 3 It can be seen that the thickness direction of the conductive connector 250 is Figure 3 In the X-axis direction, the width direction of the conductive connector 250 is Figure 2 The direction indicated by the arrow is Figure 3 The Y axis (not shown) is perpendicular to the plane XZ. The outer port of the adjustment hole 230 extends in a direction and the outer port extension direction of the connection port 220 Located on one side of the thickness direction of the conductive connector 250. The conductive connector 250 passes through the mounting end surface 240 in the direction Parallel to the Z axis, that is, with a normal plane of the circuit board 120 (almost parallel to the plane XY) passing through the conductive connector 250 as the interface, most of the circuit board 120 is located on the side opposite to the mounting cavity (lower left side in the figure), and the end of the circuit board 120 and the outer port of the adjustment hole 230 extend in the direction of and the outer port extension direction of the connection port 220 They are all located on the same side as the mounting cavity (upper right in the figure).

[0062] So, combined Figure 3 It can be seen that when the terminal block of this structure is applied to the circuit board 120 of the electronic device with the connection port arranged vertically, the extension direction of the outer port of the adjustment hole 230 is adjusted by taking the circuit board 120 as the boundary. and the outer port extension direction of the connection port 220 They are located on both sides of the circuit board 120. and the outer port extension direction of the connection port 220 The inclined setting (relative to the circuit board 120) makes it convenient for operators to disassemble with the help of tools or insert the wire 300 into the wiring port 220, and the lead-out direction and the gathering direction of the wire 300 can be changed from (one or two) right-angle bends to one obtuse-angle bend, avoiding excessive bending of the wire 300 and improving the service life of the cable.

[0063] In one embodiment, the terminal block includes multiple groups of conductive connectors 250 and elastic members 260, the housing 200 has multiple installation cavities 210, the multiple groups of conductive connectors 250 and elastic members 260 are arranged in the corresponding multiple installation cavities 210, and the multiple installation cavities 210 are respectively provided with corresponding wiring ports 220 and adjustment holes 230.

[0064] Preferably, the plurality of mounting cavities 210 in the housing 200 are arranged along a first direction. The plurality of conductive connectors 250 are arranged along a first direction on the mounting end surface 240. The first direction is the normal direction of the plane where the conductive connector 250 and the wiring port 220 are located, that is, the z-axis direction. In this embodiment, the housing 200 of a wiring terminal has only two mounting cavities 210, and the wiring terminal is also described by taking only two groups of conductive connectors 250 and elastic members 260 as an example.

[0065] In one embodiment, Figure 3As shown, the mounting structure includes an active cavity 280 located between the mounting cavity and the adjustment hole. With the intersection of the mounting cavity and the adjustment hole as the center, the active cavity 280 is located outside the intersection center and bends toward the intersection center, that is, the active cavity 280 is outside the intersection center, and in the process of extending from the mounting cavity to the adjustment hole, it arches outward to form a shape that bends toward the intersection center.

[0066] One end of the movable cavity 280 extends toward the installation cavity and the width of a section of the end is just equal to the thickness of the elastic member 260, so that one end of the elastic member 260 can be fastened after being inserted to fix the one end of the elastic member 260. The other end of the movable cavity 280 is connected to the inner port of the adjustment hole. The elastic member 260 includes a bent portion 261 located in the movable cavity 280, and a hook portion 263 and a connecting portion 262 located outside the movable cavity 280, and the two ends of the connecting portion 262 are respectively connected to the bent portion 261 and the hook portion 263. The hook portion 263 is bent toward the opposite end of the elastic member 260 and the bent portion is located at the inner port of the adjustment hole.

[0067] The other end of the elastic member 260 can directly extend to the depth of the adjustment hole after passing through the active cavity 280 , that is, the connecting portion 262 and the hook portion 263 can directly extend to the intersection center after passing through the active cavity 280 .

[0068] The active cavity 280 has an inner wall 281 and an outer wall 282. When the wire is not inserted from the connection port, the other end of the elastic member 260 can abut against the conductive connector 250. When the other end of the elastic member 260 abuts against the conductive structure, the bent portion 261 of the elastic member 260 in the active cavity 280 can fit with the inner wall 281 of the active cavity 280, at least partially, or completely.

[0069] When the wire is inserted from the wiring port between the other end of the elastic member 260 and the conductive connector 250, the other end of the elastic member 260 can be pressed against the limiting portion 310 located on the outer wall of the wire, that is, the insertion of the conductive connector 250 between the two will cause the elastic member 260 to bend and deform, and the other end of the elastic member 260 will press the wire against the conductive connector 250 to make the wire electrically contact with the conductive connector 250. At the same time, when the other end of the elastic member 260 is pressed against the limiting portion 310 located on the outer wall of the wire, the elastic member 260 can fit against the outer wall 282 of the active cavity 280 to limit the degree of bending deformation of the elastic member 260.

[0070] Before the wire 300 is inserted, since the connection portion 262 and the hook portion 263 account for a small proportion of the total length of the entire elastic member 260, these areas are relatively less likely to deform. After the wire 300 is placed, as the elastic member 260 bends to a certain extent and comes into contact with the outer wall 282 of the active cavity 280, the outer wall 282 of the active cavity 280 will provide support for the bent portion 261 of the elastic member 260. This means that most of the pressure applied by the elastic member 260 to the wire 300 is transmitted through the connection portion 262 and the hook portion 263 extending out of the active cavity 280. Given that the connection portion 262 and the hook portion 263 account for a small proportion of the entire component size, the overall deformation generated when they come into contact with the stop portion 310 on the wire 300 is mainly concentrated in these two areas. Therefore, when the hook portion 263 is engaged with the stop portion 310, the connection between them becomes firm and is not easy to be separated.

[0071] In some embodiments, one end of the active cavity 280 is communicated with the installation cavity, and the elastic member 260 is made of a conductive material so that one end of the elastic member 260 is electrically connected to the conductive connector 250 .

[0072] Specifically, the conductive connector 250 includes a connector portion 251 and a wiring portion 252 that are bent and connected. The free end of the connector portion 251 passes through the mounting end surface, and the wiring portion 252 extends to the edge of the inner port of the wiring port. One end of the elastic member 260 is electrically connected to the connector portion 251, and the other end of the elastic member 260 can press the wire tightly against the wiring portion 252. That is, the free end of the bent portion 261 of the elastic member 260 passes through the active cavity 280 and is electrically connected to the connector portion 251, and the hook portion 263 of the elastic member 260 can press the wire tightly against the wiring portion 252.

[0073] In some embodiments, the angle between the hook portion and the extension direction of the wiring port is between 5 degrees and 60 degrees. Figure 5 As shown, after the wire is inserted from the wiring port, it extends from the inner port of the wiring port into the installation cavity along the extension direction of the wiring port, and one side of the wire is in contact with the wiring portion 252 to achieve electrical connection, and the wire faces the hook portion and touches the hook portion on the other side opposite to the wiring portion. Since the extension direction of the wire and the wiring port are the same, after the end of the hook portion contacts the wire, the angle between the hook portion and the wire is equivalent to the angle between the hook portion and the extension direction of the wiring port, that is, the angle between the hook portion and the wire is 5 degrees to 60 degrees. The figure shows an implementation method in which the angle between the hook portion and the wire is set at 45 degrees.

[0074] In some embodiments, the other end of the conductive connector 250 is provided with a groove capable of accommodating the wire, and the groove extends along the length direction of the conductive connector 250. Specifically, the groove is provided at the wiring portion 252. Similarly, an arc-shaped notch can also be provided at the end of the hook portion 263, so that after the hook portion 263 abuts against the wire, the groove wall of the groove can fit the surface of the wire, thereby increasing the contact area with the surface of the wire. In this way, the current can not only flow directly to the connector portion 251 through the wire, but also flow to the connector portion 251 after passing through the hook portion 263, the connecting portion 262, and the bending portion 261 of the elastic member 260, which is equivalent to treating the elastic member 260 as another parallel wire to reduce the resistance loss of the current.

[0075] In some embodiments, the housing of the terminal block includes a main body and an end cover, and grooves corresponding to the installation cavity, the movable cavity, the adjustment hole and the wiring port are provided on the end face of one side of the main body. When the end cover is covered with the main body, the grooves are covered to form the installation cavity, the movable cavity, the adjustment hole and the wiring port, and only the hole opening is exposed from the side of the main body. The main body and the end cover can be connected by ultrasonic welding, glue bonding, snap-on connection, or by connecting concave and convex structures to fit tightly.

[0076] In one embodiment, Figure 6 As shown, the housing 200 has two oppositely disposed connection end surfaces 270, and the two opposite surfaces are oppositely disposed along the z-axis direction. A slot 271 is provided on one of the connection end surfaces 270, and an insertion strip 272 is provided on the other connection end surface 270. The slot 271 and the insertion strip 272 extend on the surfaces of their respective connection end surfaces 270, respectively, so that different connection terminals can be extended through the mortise and tenon connection of the slot 271 and the insertion strip 272.

[0077] Preferably, the angle between the extending direction of the slot 271 and the insert 272 and the direction of the conductive connector 250 is between 0° and 90°. In this embodiment, 0° is used as an example for explanation, that is, the extending direction of the slot 271 and the insert 272 is parallel to the direction of the conductive connector 250, that is, in the same direction.

[0078] Further, one of the connection end faces 270 of the housing 200 is provided with a plurality of slots 271, and the other connection end face 270 is provided with a plurality of inserting strips 272. The plurality of slots 271 are arranged in parallel and alternately, and the plurality of inserting strips 272 correspond to the plurality of slots 271. In this embodiment, only two slots 271 and two inserting strips 272 arranged opposite to each other are taken as an example for description.

[0079] In addition, the utility model also provides an electronic device in a second aspect, such as Figure 2As shown, the electronic device includes a shell 110 and a circuit board 120 arranged in the shell 110, and the edge of one side of the circuit board 120 is sequentially provided with a plurality of jacks, the shell has a mounting portion, a wiring port, and a housing cavity for accommodating the circuit board; the mounting portion is located on the back of the shell; the mounting portion is used to be detachably connected to the guide rail of the control cabinet; the wiring port is connected to the housing cavity; the wiring port extends from a direction close to the mounting portion to a direction away from the mounting portion on at least one of the top surface and the bottom surface of the shell; the width of the back of the shell is less than the length of the wiring port in the extension direction; the circuit board is arranged in the housing cavity along the extension direction of the wiring port, the jack is close to the wiring port and the jack is connected to the conductive joint of the wiring terminal provided in the first aspect. The reasoning process of the beneficial effects of the electronic device provided by the utility model and the aforementioned wiring terminal is similar, and will not be repeated here.
