DETAILED DESCRIPTION

[0027] 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.

[0028] 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.

[0029] The circuit boards of conventional horizontal electrical or electronic equipment are all arranged transversely (horizontally). When connecting the wiring terminals, the plug 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.

[0030] For example, in Figure 1 The figure shows a schematic diagram of the structure of a conventional horizontal electronic device, specifically a schematic diagram of the structure of a controller. In the figure, the circuit board 120 is horizontally arranged in the housing 110 of the 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 figure is a front view of a PLC (programmable logic controller) along the y-axis direction.

[0031] 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 of the circuit board 120. The plug connector 250 of the connection terminal is inserted vertically downward and perpendicular to the surface of the circuit board 120 into the corresponding mounting opening on the circuit board 120 for connection. The connection terminal is connected to the cable conductor 300 on the side away from the circuit board 120 in the horizontal direction, and the connection direction of the cable conductor 300 and the connection terminal is parallel to the circuit board 120.

[0032] To facilitate later maintenance, inspection or replacement, the terminal block and the cable conductor 300 are connected in a detachable manner, such as a spring clamping structure or a screw-type terminal block. Regardless of the structure of the terminal block, an adjustment hole 230 is provided on the terminal block for tools to enter for disassembly.

[0033] Usually, the adjustment hole 230 is arranged on the side of the connection terminal opposite to the circuit board 120, and the matching housing 110 needs to be designed to have a special movable structure (such as a flip cover or a sliding cover) to provide a tool (such as a screwdriver) to accommodate the connection terminal of the spring clamping structure or the screw-type connection terminal and the cable during maintenance, replacement and disassembly. The multiple connection terminals are arranged in a straight line along the y-axis direction (i.e., the length direction of the circuit board 120).

[0034] The direction in which the cable conductor 300 is connected to the terminal block does not necessarily need to be set to an angle parallel to the circuit board 120, and the setting direction of the adjustment hole 230 (opening) on ​​the terminal block is not absolutely perpendicular to the circuit board 120. According to actual conditions, the direction in which the cable conductor 300 is connected to the terminal block and the setting direction of the adjustment hole 230 can be flexibly adjusted within a certain range. However, no matter how it is adjusted, in short, on the circuit board 120, a plurality of plug connectors 250 arranged along the y-axis are used as the interface, and the adjustment hole 230 and the cable conductor 300 are both located on the side away from the circuit board 120 or one of them is exactly located on the interface. At the same time, with the circuit board 120 as the interface, the extension (lead-out) direction of the adjustment hole 230 and the cable conductor 300 is either perpendicular to the surface of the circuit board 120 or parallel to the circuit board 120, or is located within the angle range between the two, and will not cross the plane where the surface of one side of the circuit board 120 is located to reach the area where the surface of the other side of the circuit board 120 is located, that is, Figure 1 The rounded rectangular area with dotted shadow in the middle.

[0035] The circuit board 120 of this electronic device is vertically arranged, and when multiple wiring terminals are installed on the surface of the circuit board 120, they are also arranged vertically from top to bottom. If the above-mentioned existing wiring terminals of this structure continue to be used, either the cables are made perpendicular to the surface of the circuit board 120, which will increase the bending angle when multiple cables are subsequently gathered, or the cable conductors 300 are led out parallel to the surface of the circuit board 120, which will make the adjustment holes 230 face one side, causing inconvenience to the operator when disassembling from the front. In short, when the existing wiring terminals are directly used on this type of electronic device (with the wiring ports arranged vertically), it is difficult to take into account both cable gathering and convenient disassembly.

[0036] To this end, as a 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 device here is such as an Internet of Things controller, a DTU (DTU, Data Transfer unit, Internet of Things data transmission unit), a digital base (Digital Infrastructure, DI), a programmable logic controller (Programmable Logic Controller, PLC), and it can also be an electronic and electrical device that uses the series and parallel combination of mechanical contacts of various electrical components without limitation.

[0037] like Figure 2 and Figure 3As shown, the wiring electronic device includes a housing 200 and a wiring assembly. The housing 200 has a mounting cavity 210, and the housing 200 is provided with a wiring hole 220 and an adjustment hole 230 connected to the mounting cavity 210. The wiring hole 220 is used to insert the cable conductor 300, the mounting cavity 210 is located at the end of the wiring hole 220, and the adjustment hole 230 is connected to the mounting cavity 210 from the side. When the cable conductor 300 is inserted into the mounting cavity 210 from the wiring hole 220, the portion of the cable conductor 300 inserted into the mounting cavity 210 can be electrically connected to the wiring assembly.

[0038] Specifically, the wiring assembly includes a plug connector 250 and a detachable connector 260. The housing 200 has a mounting end surface 240, which is an outer wall of the housing 200 at the end of the extension direction of the mounting cavity 210. One end of the plug connector 250 passes through the mounting end surface 240, and the other end of the plug connector 250 extends into the mounting cavity 210. The detachable connector 260 is located in the mounting cavity 210 and is used to electrically connect the cable conductor 300 to the other end of the plug connector 250.

[0039] The outer port of the adjustment hole 230 is on the surface of the outer shell 200, and the inner port of the adjustment hole 230 is on the side wall of the installation cavity 210. The detachable connecting piece 260 is opposite to the inner port of the adjustment hole 230, so that the detachable connecting piece 260 can be operated when the tool is inserted through the adjustment hole 230, so as to facilitate the installation or removal of the cable conductor 300.

[0040] When the terminal block is connected to an electronic device, the mounting end face 240 is used to dock with the surface of the circuit board 120 in the electronic device. The circuit board 120 of the docking device is provided with a jack, which corresponds to the plug connector 250. 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 hole 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 hole 220 is located are oriented in different directions.

[0041] It should be noted that the plug connector 250 here is generally perpendicular to the mounting end face 240 and extends outward, and the angle (error) between the two is allowed to be within the range of ±10°, that is, the mounting end face 240 is usually parallel to the normal plane corresponding to the wiring head, and the angle between the mounting end face 240 and the normal plane of the wiring head is 80° to 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 hole 220 is usually perpendicular to the surface on which it is located, that is, the surface on which the outer port of the wiring hole 220 is located is parallel to the normal plane corresponding to the extension direction of the outer port.

[0042] 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 hole 220 is located, or the mounting end surface 240 can be designed to be an arc surface, a curved surface, or other discontinuous surfaces. 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 hole 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 hole 220 can also be regarded as the surface where the outer port of the wiring hole 220 is located, or the normal plane corresponding to the direction of the plug connector 250 can be regarded as the mounting end surface 240.

[0043] 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 hole 220 is located to connect the two, and there is no limitation here.

[0044] Furthermore, the exposed portion of the plug connector 250 on 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 hole 220 are all in the same plane. Figure 3 The plane formed by the xy axis is parallel to the plane formed by the xy axis. The plane is divided by the plug connector 250, and the adjustment hole 230 and the wiring hole 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 plug connector 250, the external port of the adjustment hole 230 and the external port of the wiring hole 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.

[0045] 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 plug connector 250 is located faces inward (the surface facing the circuit board 120), the surface where the external port of the wiring hole 220 is located faces outward, and the surface where the external port of the adjustment hole 230 is located is located between the two and the two ends are respectively connected to the two. 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 hole 220 is located can face the left and right sides of the circuit board 120 respectively, which is convenient for later maintenance and disassembly.

[0046] Specifically, Figure 3 As shown, relative to the direction in which the plug connector 250 passes through the mounting end surface 240 and the extension direction of the outer port of the wiring hole 220 The extension direction of the outer end of the adjustment hole 230 It is more inclined to the side close to the plug connector 250. That is, in the figure, ∠AOB is smaller than ∠BOC.

[0047] Optionally, the direction in which the plug 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°.

[0048] The direction in which the plug connector 250 passes through the mounting end surface 240 and the extension direction of the outer port of the wiring hole 220 The angle between them is an obtuse angle, that is, ∠AOC is an obtuse angle.

[0049] In a preferred embodiment, ∠BOC is between 70° and 110°, preferably a right angle.

[0050] For example, ∠AOB is 45°, ∠AOC is 135°, that is, ∠BOC is a right angle.

[0051] In one embodiment, the plug connector 250 is in the form of a sheet having a width and a thickness. Figure 2 and Figure 3 It can be seen that the thickness direction of the plug connector 250 is the x-axis direction, and the width direction of the plug connector 250 is the z-axis direction (not shown in the figure). and the outer end extension direction of the wiring hole 220 Located on one side of the thickness direction of the plug connector 250. The plug connector 250 passes through the mounting end surface 240 in the direction Parallel to the y-axis, that is, with a normal plane of the circuit board 120 passing through the plug connector 250 as the interface, most of the circuit board 120 is located on one side (the right side in the figure), and the end of the circuit board 120 and the outer end of the adjustment hole 230 extend in the direction and the outer end extension direction of the wiring hole 220 Both are located on the other side (the left side in the picture).

[0052] So, combined Figure 7 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 end extension direction of the wiring hole 220 They are located on both sides of the circuit board 120. and the outer port extension direction of the wiring hole 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 cable conductor 300 into the wiring hole 220, and the lead-out direction and the gathering direction of the cable conductor 300 can be changed from (one or two) right-angle bends to one obtuse-angle bend, avoiding excessive bending of the cable conductor 300 and improving the service life of the cable.

[0053] In one embodiment, the wiring terminal includes a plurality of wiring components, the housing 200 has a plurality of mounting cavities 210, the plurality of wiring components are arranged in the corresponding plurality of mounting cavities 210, and the plurality of mounting cavities 210 are respectively provided with corresponding wiring holes 220 and adjustment holes 230.

[0054] Preferably, the plurality of mounting cavities 210 in the housing 200 are arranged along a first direction. The plurality of plug 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 plug connector 250 and the wiring hole 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 wiring assemblies as an example.

[0055] In one embodiment, Figure 2 and Figure 3As shown, the detachable connector 260 includes an adjusting screw 261. The adjusting screw 261 is disposed in the inner port of the adjusting hole 230 and connected to the adjusting hole 230. The adjusting screw 261 is located at the end of the mounting cavity 210 and is disposed opposite to the outer side wall of the other end of the plug connector 250. When the adjusting screw 261 moves axially in the adjusting hole 230, it can adjust the connection strength between the cable conductor 300 and the plug connector 250. In order to increase the convenience of production and assembly, in this embodiment, the detachable connector 260 also includes a sleeve disposed in the mounting cavity 210. The sleeve is preferably a metal sleeve 263. An opening of the metal sleeve 263 is disposed in the wiring hole 220. A screw hole is opened in the side wall of the metal sleeve 263. The screw hole is opposite to the inner port of the adjusting hole 230. The adjusting screw 261 is disposed in the screw hole and is threadedly connected to the metal sleeve 263 through the screw hole. It is easy to understand that one of the adjusting screw 261 and the metal sleeve 263 is relatively fixed with the adjusting hole 230 in the axial direction of the adjusting hole 230, and when the adjusting screw 261 is rotated, the other can move in the adjusting hole 230 along the axial direction of the adjusting hole. In this embodiment, the adjusting screw 261 is axially fixed in the adjusting hole, but can be rotated freely to drive the metal sleeve 263 to move along the axial direction of the adjusting hole 230. The cable conductor 300 can be inserted between the side wall of the metal sleeve without screw holes and the plug connector 250. When the metal sleeve 263 is driven by the adjusting screw 261 to move along the axial direction of the adjusting hole toward the outer port of the adjusting hole, the side wall of the metal sleeve without screw holes and the plug connector 250 press the cable conductor; or the metal sleeve is fixed, and the plug connector 250 is driven by the adjusting screw 261 to move toward the cable conductor 300 until the plug connector 250 and the cable conductor 300 are fastened against the inner wall of the metal sleeve.

[0056] In another embodiment, Figure 4As shown, the detachable connector 260 includes an elastic buckle 262. The elastic buckle 262 and the outer side wall of the other end of the plug connector 250 are arranged opposite to each other in the installation cavity 210, so that when the cable conductor 300 is inserted therebetween, the elastic buckle 262 can make the cable conductor 300 abut against the outer side wall of the plug connector 250. The surface of the cable conductor 300 has an annular groove 310, and the groove 310 has an inclined surface on the side away from the end of the cable conductor 300. The elastic buckle 262 is formed by connecting and bending a straight portion and a curved adjusting portion at one end, wherein the adjusting portion is located at the inner port of the adjusting hole 230 and is opposite to the inner port, and the curved adjusting portion provides elastic deformation and generates restoring elastic force, and at the same time provides a center of a circle to make the straight segment arc movable, and the straight portion fits with the inclined surface at the end away from the bend, so that when the cable conductor 300 is inserted between the plug-in portion and the straight portion, the end of the straight portion that fits with the inclined surface can cooperate with the groove 310, and at the same time, the adjusting portion is elastically deformed after bending and presses the cable conductor 300 to the side wall of the plug connector, so as to prevent the cable conductor 300 from escaping from the wiring hole 220, and the straight portion The length is greater than the length of the inclined surface, so there is a gap between the end near the bent connection and the cable conductor 300, so that the straight portion forms a lever-like structure on the inclined surface of the groove 310. When the cable conductor 300 is removed with the help of a tool, it is only necessary to insert the tool into the adjustment hole 230 and press the end where the adjustment portion is bent and connected to the straight portion, and the other end of the straight portion will be lifted. When the end of the straight portion away from the groove fits with the surface of the cable conductor 300, the other end of the straight portion will be completely separated from the groove 310, thereby releasing the axial restriction on the cable conductor 300, and the cable conductor 300 can be pulled out from the wiring hole 220.

[0057] In one embodiment, Figure 5 , Figure 6 and Figure 7 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 connected through the mortise and tenon connection of the slot 271 and the insertion strip 272.
