Description

Technical Field

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

[0002] Plug-in terminals, as a connector that can be repeatedly removed and inserted, are widely used in electronic devices, providing convenience and flexibility for users. This type of terminal usually consists of a plug (male) and a socket (female), which can quickly connect and disconnect the circuit.

[0003] In order to ensure the uniqueness and accuracy of the connection, the limiting structure or shape of the socket is usually designed to be non-centrally symmetrical, and the corresponding plug must also be designed to have a matching limiting structure or shape. In this way, the plug can only be inserted into the socket along a predetermined angle to achieve correct assembly. However, this design also brings certain limitations. For example, the cable outlet direction is usually fixed to the axial direction of the plug. Once the plug is connected to the socket, the cable can only be led out in one direction and the direction cannot be adjusted according to actual needs. At the same time, if the cable lead-out directions of multiple plugs are the same, the cables will be too concentrated and cannot be effectively distributed to other directions.

[0004] In addition, in order to improve the connection efficiency, the female and male connectors are usually designed as a multi-in-one form, that is, a female connector and its paired male connector can achieve the connection of more than two cables. However, this integrated design also brings problems. First, it leads to too many subcategories of terminals, which is not conducive to efficient and standardized production. Secondly, when the female connector is not fully used, the corresponding male connector still needs to be invested, resulting in waste. What's more serious is that once one of the positions or one hole is damaged, it needs to be replaced as a whole, which further increases the waste. Utility Model Content

The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0046] Example:

[0047] As a first aspect of the utility model, there is provided a terminal pair, which is applied to electronic devices with vertically or horizontally arranged wiring ports, so that multiple orientations can be selected when the electronic devices are connected to external cable conductors. Applicable electronic devices include, but are not limited to, Internet of Things controllers, DTUs (Data Transfer Units), Digital Infrastructures (DIs), Programmable Logic Controllers (PLCs), and may also be electronic and electrical devices composed of series and parallel combinations of mechanical contacts of various electrical components, without limitation.

[0048] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the terminal pair mainly includes a socket 10 and a plug 20, which adopt a plug-in detachable connection structure. The socket 10 is welded on the circuit board of the electronic device when in use. The socket is located inside the shell and is provided with a slot 11. The slot 11 of the socket 10 faces the wiring end surface of the shell 24 of the electronic device, and the slot is aligned with the opening on the wiring end surface, so that the plug 20 can be inserted into the slot 11 through this opening for plug-in connection. Figure 5 and Figure 6 .

[0049] The plug 20 is provided with a plug end 21 and a wiring hole 22. The plug end 21 is used for plugging and unplugging with the slot 11 of the socket 10. In the connected state, the plug end 21 is inserted into the slot 11 from the opening on the wiring end surface, facing inward, while the wiring hole 22 is located outside the wiring end surface, and its opening direction faces outward and tilted at a certain angle to one side.

[0050] The plug connector 28 includes a body, and its plug end 21 is arranged on the body and extends outward from the surface of the body for a distance. Generally, the extension length of the plug end 21 matches the depth of the slot 11, so that the plug end 21 can be inserted into the depth of the slot 11 to achieve electrical connection between the conductors. The wiring hole 22 is arranged on the body, and its direction forms two nearly opposite directions with the extension direction of the plug end 21 but with an angle. Specifically, there is a non-zero angle between the extension direction of the plug end 21 and the opening direction of the wiring hole 22, see Figure 4 , the angle is greater than or equal to 90 degrees and less than 180 degrees. Such a configuration enables the connection terminal pair to be mounted on the circuit board of the electronic device with the plug end 21 facing inward (facing the electronic device), and the connection hole 22 of the plug 20 is located outside the connection terminal surface of the electronic device, with the opening direction facing outward and tilted toward one side at a certain angle.

[0051] In the side wall of the plug end 21 and the inner wall of the slot 11, one is provided with a first limiting portion 31 and a second limiting portion 32 in the circumferential direction, and the other is provided with a third limiting portion 33. In other words, the first limiting portion 31 and the second limiting portion 32 can be provided on the outer side of the side wall of the plug end 21 and distributed in the circumferential direction, while the third limiting portion 33 is provided on the inner wall of the slot 11; or, the first limiting portion 31 and the second limiting portion 32 are provided on the inner wall of the slot 11 and distributed in the circumferential direction, while the third limiting portion 33 is provided on the outer side wall of the plug end 21.

[0052] Both configurations are feasible, and technicians in this field can flexibly choose one based on actual needs, and there is no limitation here.

[0053] The third limiting portion 33 can selectively cooperate with the first limiting portion 31 and the second limiting portion 32 at two different positions. When the third limiting portion 33 is in a matching state with either the first limiting portion 31 or the second limiting portion 32, the wiring hole 22 can guide the cable to be output from directions corresponding to the two different positions.

[0054] For ease of explanation, the following is an example in which the first limiting portion 31 and the second limiting portion 32 are arranged on the side wall of the plug end 21, and the third limiting portion 33 is arranged on the inner wall of the slot 11. Since the first limiting portion 31 and the second limiting portion 32 on the side wall of the plug end 21 are separated by a certain distance or angle, the plug end 21 of the plug 20 can be inserted into the slot 11 by rotating a certain angle along the circumferential direction of the insertion direction, so that the third limiting portion 33 is aligned with the first limiting portion 31, or the third limiting portion 33 is aligned with the second limiting portion 32. By selecting to align with different limiting portions, the exposed wiring hole 22 of the plug end 21 will also face different angles accordingly, so that the wiring hole 22 guides the cable outlet in the required direction. When more cables are concentrated in a certain direction, or the installation position of the electronic equipment determines that the cable preferably has a specific direction, the terminal pair in this embodiment can provide multiple coordination directions, so that the staff can flexibly select one of the coordination directions according to the actual situation during installation, so it has higher flexibility and wider applicability.

[0055] In some embodiments, Figure 5 As shown, a cylindrical plug-in terminal and a matching slot are shown. The third limiting portion 33 located on the side of the plug-in terminal is a convex portion, while the first limiting portion 31 and the second limiting portion 32 located on the inner wall of the slot are concave portions, and the two are arranged opposite to each other. When the plug-in terminal is plugged into the slot, the third limiting portion 33 is aligned with the first limiting portion 31, or the third limiting portion 33 is aligned with the second limiting portion 32. The first limiting portion and the second limiting portion have the same structure, and the only difference is that the positions or angles set on the inner wall of the slot are different.

[0056] like Figure 6 As shown, in some other embodiments, the cylindrical plug-in end is different from the matching slot in that the third limiting portion 33 located on the inner wall of the upper slot is a convex portion, while the first limiting portion 31 and the second limiting portion 32 located on the side of the plug-in end are concave portions, and the two are arranged opposite to each other.

[0057] In the above two embodiments, only one set of limiting parts (first limiting part, second limiting part and third limiting part) is provided on the plug end and the slot, and both the convex part and the concave part are semicircular arc shapes. It should be noted that multiple sets of limiting parts on the plug end and the slot can be provided, and the shapes and sizes of the convex part and the concave part can be flexibly changed according to the situation without limitation.

[0058] For example, Figure 7 As shown, in some other embodiments, the cylindrical plug-in end and the matching slot show the first limiting portion, the second limiting portion and the third limiting portion using two implementation modes at the same time.

[0059] The first limiting portion 31 and the second limiting portion 32 are recessed, and the third limiting portion 33 is a convex portion. The recessed portion and the convex portion are respectively in two different shapes. Specifically, the second limiting portion of the first limiting portion includes a semicircular recessed portion on the side wall of the plug-in end and a triangular recessed portion on the inner wall of the slot. The third limiting portion includes a triangular convex portion on the side wall of the plug-in end and a semicircular convex portion on the inner wall of the slot.

[0060] It should be noted that after the plug-in end is docked with the slot, the conductor located at the center of the slot will be electrically connected to the wiring assembly inside the plug-in end. In order to ensure that the plug-in end can achieve stable electrical connection with the slot regardless of the angle at which it is connected, one end of the conductor located inside the slot extends along the axis of the slot. At the same depth of the slot, the distance between the inner wall of the slot and the conductor is equal everywhere, that is, the inner wall of the slot is a convolute surface, such as a cylindrical side or a truncated cone side. Similarly, the side of the plug-in end is also a convolute surface. The convex and concave parts are relative to the convolute surface, and the convex part is not limited to a local part. For example, the cross-sectional shape of the slot adopts a polygon such as a triangle or a rectangle. The polygon has edges and corners. The slot forms a concave part at the corners of the corresponding polygonal cross section, and the plug-in end can form a convex part at the corresponding polygonal cross section.

[0061] In some embodiments, Figure 8 As shown, the slot 11 has two opposite inner walls, forming a rectangular cross-section structure, and the cross-sectional shape of the plug-in end is adapted to the slot. This design enables the slot 11 to have four inner walls, two pairs of which are arranged oppositely. Under this configuration, the two opposite diagonals of the inner wall of the slot respectively constitute the first limit portion 31 and the second limit portion 32, and the other two opposite diagonals also constitute the first limit portion and the second limit portion in another direction. Or two adjacent diagonals located on the same side constitute the first limit portion, and two adjacent diagonals located on the other opposite side constitute the second limit portion. The positional relationship between the first limit portion and the second limit portion along the circumference of the slot 11 corresponds to an arc, which is π, meaning that the two limit portions are at both ends of the diameter.

[0062] Since the direction in which the wiring hole 22 guides the cable outlet is determined by the circumferential curvature between the first limiting portion 31 and the second limiting portion 32, this curvature can be adjusted according to the needs of the actual application scenario. Specifically, when the first limiting portion 31 and the second limiting portion 32 are arranged on the plug-in terminal 21 or the slot 11, or when the cross-section of the plug-in terminal 21 or the slot 11 is a polygon with a limiting portion formed at the corner, the curvature between them can be set to any value between 0.25π and π to adapt to different usage requirements. These possible values ​​include but are not limited to 0.25π, π / 3, 0.5π, 2π / 3, 0.75π, etc., providing flexible design options.

[0063] The cross-sectional shape of the plug-in end 21 is adapted to the design of the slot 11 and is also rectangular, so it also has two opposite side walls. The edges and corners on the side walls of the plug-in end form a plurality of symmetrical third limiting portions.

[0064] The third limiting portions 33 are arranged on these side walls, respectively cooperating with the first limiting portions 31 and the second limiting portions 32 on the slot 11. It is worth noting that since the slot 11 and the plug-in terminal 21 are both rectangular in cross-section, there is a centrally symmetrical relationship between the first limiting portion 31 and the second limiting portion 32, and similarly, there is a similar symmetry between the two third limiting portions 33. This means that after the first limiting portion 31 is rotated 180 degrees around a certain axis, it can completely overlap with the second limiting portion 32. Therefore, in this embodiment, by providing two third limiting portions 33, even after rotating 180 degrees, they can still cooperate with the first limiting portion 31 and the second limiting portion 32 to ensure that the plug-in terminal 21 and the slot 11 are fixed in the circumferential direction. In some alternative embodiments, such as Figure 5 As shown, only one third limiting portion 33 may be provided on the side wall of the plug end 21 , which can also realize the function of selectively connecting with the first limiting portion 31 and the second limiting portion 32 .

[0065] In addition, the plug end 21 and the slot 11 can be fastened in the axial direction (i.e., the plug-in direction) by interference fit. For further convenience, a snap-fit ​​piece can be added in this direction to achieve a detachable connection, providing more convenience and adaptability. These possibilities will not be described in detail here.

[0066] In some embodiments, both the plug end and the slot are thin-walled structures and adopt a polygonal structure, such as a rectangular structure, so that the thin-walled part is a plane. To enhance its structural strength, a reinforcing rib is provided on one of the side wall of the plug end and the inner wall of the slot. In the circumferential direction, the reinforcing rib is located on the plane between two adjacent limiting portions, and the reinforcing rib extends along the plugging and unplugging direction. Figure 1 , Figure 3 and Fig. 9As shown, the reinforcing ribs 34 arranged on the inner wall of the rectangular slot are shown, and the side grooves 35 on the side wall of the plug end that match the reinforcing ribs 34 are also shown. This structural layout helps to enhance the strength of the slot 11, thereby providing additional support for the slot wall. The side grooves on the side wall of the plug end, in addition to being able to cooperate with the reinforcing ribs, can also save the material of the plug end to a certain extent.

[0067] In some embodiments, the socket 10 is provided with mortise and tenon structures on two opposite outer walls outside the slot 11, for connecting with other sockets 10. The slot 11 is located between the two opposite outer walls. Fig.10 As shown, when a plurality of such terminal pairs are used on the circuit board of the electronic device, they are arranged at a uniform angle so that the sockets 10 of two adjacent terminal pairs can be detachably connected through the mortise and tenon structure of the outer wall.

[0068] Specifically, the mortise and tenon structure includes a matching mortise groove 41 and a tenon 42, and the extending direction of these structures is consistent with the opening direction of the slot 11. Among the two opposite outer walls of the socket 10, one outer wall is provided with the mortise groove 41, and the other outer wall is provided with the tenon 42. For example, the mortise groove 41 can be in the form of a dovetail groove, and the matching tenon 42 is a dovetail head. Through such a design, multiple terminal pairs can be connected to each other through their respective mortise grooves 41 and tenons 42, and combined into a multi-terminal assembly as needed.

[0069] In order to further improve the connection convenience between multiple terminal pairs, on two opposite outer walls of the socket 10, one outer wall is alternately provided with tenons 41 and tenons 42, and the other outer wall is correspondingly provided with matching tenons 42 and tenons 41. Specifically, Figure 1 As shown, a pair of mortise grooves 41 and tenons 42 are respectively designed on the first outer wall and the second outer wall of the socket 10, so that the mortise grooves 41 on the first outer wall are opposite to the tenons 42 on the second outer wall, and the tenons 42 on the first outer wall are opposite to the mortise grooves 41 on the second outer wall. Such a layout enables the first outer wall of one socket 10 to be connected to the first outer wall of another socket 10 or the second outer wall of another socket 10 through the mortise and tenon structure when the sockets 10 with multiple terminal pairs are connected through the mortise and tenon structure. There is no need to consider whether the first outer wall or the second outer wall is connected, so it is more convenient to connect.

[0070] The plug 20 includes a main body 23, and the plug end 21 extending from the main body can be fully inserted into the slot 11 when the plug 20 is plugged in and out of the socket 10. After the plug is plugged in, only the main body 23 of the plug 20 remains exposed, which ensures the stability of the connection and facilitates the management and maintenance of the line.

[0071] In order to better connect multiple terminal pairs, the two opposite outer walls of the main body 23 of the plug are also provided with the same mortise and tenon structure as that on the socket 10. When the plug end 21 and the slot 11 are in a mating state, the mortise and tenon structure on the main body 23 and the mortise and tenon structure on the socket 10 form a continuous connection. Figure 1 As shown, after the plug end 21 is completely inserted into the slot 11 of the socket 10, the tenon groove 41 on the plug 20 is connected to the tenon groove 41 on the socket 10, and the tenon 42 on the plug 20 is also connected to the tenon 42 on the socket 10. Such a design makes the structure of the entire connection system more stable, and the wiring hole 22 is arranged on the side wall between the two opposite outer walls of the main body 23, which is convenient for the introduction and extraction of cables.

[0072] In some embodiments, the plug 20 is composed of a housing 24 and a wiring assembly. The housing 24 is made of an insulating material, such as plastic, to provide physical protection for the entire plug. The wiring assembly is a conductor part that is responsible for making an effective electrical connection with the conductor of the cable. Figure 4 and Fig.11 As shown, a mounting cavity 26 is provided inside the housing 24 for accommodating and fixing the wiring assembly. An adjustment hole 27 and a wiring hole 22 are also provided on the housing 24, and both holes are connected to the mounting cavity 26 to facilitate the access and adjustment of the cable.

[0073] In this embodiment, the plug end 21 is an extension portion provided on the housing 24. Specifically, the housing 24 includes a body and the plug end 21 extending outward from the body surface for a certain distance. The end face of the plug end 21, the surface where the outer port of the adjustment hole 27 is located, and the surface where the outer port of the wiring hole 22 is located, the three surfaces are oriented in different directions, so this design is conducive to reducing erroneous operations and making the direction of the cable clearer and more orderly.

[0074] Specific as Fig.10 and Fig.11 As shown, the terminal pair is installed on the edge of the circuit board of the electronic device. In the figure, the arrow x indicates the extension direction of the edge of the circuit board, which is also the thickness direction of the terminal pair; the arrow y indicates the length direction of the terminal pair, that is, the opening direction of the slot 11 on the socket 10 and the extension direction of the plug end 21 on the plug 20; the arrow z indicates the width direction of the terminal surface on the housing of the electronic device.

[0075] The socket 10 and the plug 20 are provided with mortise and tenon structures on two opposite surfaces in the thickness direction thereof, and these structures are fixed by cooperating with each other. Around the circumference in the thickness direction thereof, the end surface of the plug end 21, the outer end of the wiring hole 22 and the outer end of the adjustment hole 27 are arranged in sequence clockwise or counterclockwise. Fig.11Taking a terminal pair in the example, arrow B points to the direction of the wiring hole 22, arrow A points to the direction of the adjustment hole 27, arrow C points to the extension direction of the plug end 21, and O is the center of ABC. In the circumferential direction centered on the thickness direction of the terminal pair, that is, on the plane formed by z, o, and y, ∠COB and ∠COA are both selected values ​​between 90 degrees and 180 degrees, and ∠BOA is between 45 degrees and 135 degrees. This layout ensures that the outer port surface of the adjustment hole 27, the end face of the plug end 21, and the outer port surface of the wiring hole 22 are all oriented differently.

[0076] like Fig.11 As shown, through the above design, when the circuit board is installed vertically, the outer port of the adjustment hole 27 and the outer port of the wiring hole 22 are respectively located on both sides of the circuit board. Since the extension direction of the two ports is inclined relative to the circuit board, it is more convenient for operators to remove or insert cables. In addition, the cable lead-out direction and the cable gathering direction are changed from one or two right-angle bends to one obtuse bend, which reduces excessive bending of the cable and improves the service life of the cable.

[0077] In some embodiments, the wiring assembly includes a plug connector 28 and a detachable connector. One end of the plug connector 28 is exposed through the end surface of the plug terminal 21, and the other end of the plug connector 28 is in the installation cavity 26. The detachable connector is located in the installation cavity 26 for electrically connecting the cable conductor to the other end of the plug connector 28, and the detachable connector is opposite to the inner end of the adjustment hole 27.

[0078] Specifically, in some embodiments, the detachable connection member includes an adjustment screw 30. The screw is disposed at and connected to the inner end of the adjustment hole 27, and is located at the end of the mounting cavity 26, opposite to the outer side wall of the plug connector 28. When the adjustment screw 30 moves axially in the adjustment hole 27, the connection strength between the cable conductor and the plug connector 28 can be adjusted, thereby ensuring the reliability and stability of the electrical connection.

[0079] In some alternatives, the detachable connector may use an elastic buckle to replace the adjustment screw 30. Figure 4 As shown, the elastic buckle is installed in the installation cavity 26. When the cable conductor is inserted into the deep of the installation cavity 26 through the wiring hole 22 and contacts the plug connector 28, the elastic buckle can firmly press the cable conductor against the plug connector 28 for fixation. If disassembly is required, a tool can be inserted through the adjustment hole 27 to apply pressure to the elastic buckle to release the cable conductor.

[0080] Furthermore, the outer wall of the socket 10 is located outside the slot 11 and is opposite to the inner wall of the slot 11. The socket 10 also includes a conductor, which is usually made of metal, such as a copper sheet or a copper pin. One end of these conductors is set in the slot 11, and the other end extends through the outer wall of the socket 10. When the socket 10 is connected to the plug 20, one end of the conductor forms an electrical connection with the wiring assembly in the plug 20, thereby ensuring the conductivity of the entire circuit.

[0081] like Fig.11 As shown, an implementation of a conductor part in the slot 11 of the socket 10 is shown. The conductor part is a metal part, which is L-shaped as a whole and consists of two sections, namely the first section and the second section, which are connected as a whole and can be formed by bending. The first section is located at the bottom of the slot 11 and is centrally arranged, for example, positioned on the center line. One end of it is buried in the bottom wall of the slot bottom, and the other end extends toward the slot. Correspondingly, a corresponding socket is provided on the plug end 21 of the plug 20 so that the first section can be inserted. The wiring assembly inside the plug 20 includes a conductor, which extends to the socket and forms a part of the socket hole wall, so that it can be electrically connected to the first section after it is inserted.

[0082] One end of the second section is connected to the first section, and the other end passes through the outer wall of the socket 10, specifically, passes through from between the first limiting portion 31 and the second limiting portion 32 to the outer wall corresponding to the first limiting portion 31, or passes through from between the first limiting portion and the second limiting portion 32 to the outer wall corresponding to the second limiting portion 32. When the socket 10 is mounted on the circuit board of the electronic device, the outer wall through which the second section passes is fitted with the surface of the circuit board as a connecting end face, and the second section is inserted into a preset hole on the circuit board and fixed by welding to achieve electrical connection with the circuit on the circuit board.

[0083] In addition, the utility model also provides an electronic device, such as Fig.11 and Fig.12 As shown, the electronic device comprises a housing, a circuit board arranged in the housing, and at least one of the above-mentioned terminal pairs. The circuit board is provided with a plurality of wiring ports, and at least one socket 10 of the wiring terminal pair corresponds to at least one wiring port of the wiring ports. The wiring ports are arranged on the surface of one side of the circuit board along the extension direction of the edge of the circuit board. The housing has a wiring end face, and the edge of the wiring port on the circuit board is close to the wiring end face, and the plug 20 of at least one wiring terminal pair is exposed from the opening on the wiring end face.

[0084] By adopting the above-mentioned terminal pairs, the electronic device can combine the required number of terminal pairs according to the number of wiring required, and connect them together through the mortise and tenon structure. The terminal pairs provide at least two matching orientations, so that the staff can choose the best orientation according to the actual situation. When the device function is expanded and the number of wiring is increased in the later stage, the lead-out cable direction of all terminal pairs can also be readjusted and planned, so as to reasonably arrange the lines in the electrical cabinet and make full use of the wiring space. In particular, when the electronic device adopts a vertically arranged circuit board, that is, the back of the shell is fixed on the mounting plate of the electrical cabinet, the arrangement direction of multiple terminal pairs is perpendicular to the mounting plate of the electrical cabinet, which effectively utilizes the space in the vertical direction and saves the space of the electrical cabinet. In addition, when the outer port extension direction of the adjustment hole 27 of the terminal pair and the outer port extension direction of the wiring hole 22 are respectively located on both sides of the circuit board and are tilted, this lead-in method can be operated from the left and right directions during installation and removal. Compared with the prior art that needs to be operated in the horizontal and vertical directions, the terminal pairs of the electronic device of this embodiment are less affected by the position of the terminal and are more convenient to operate.

[0085] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention shall be included in the scope of the claims.
