Description

Terminal and conductive panel assembly

Technical Field

The present utility model relates to the field of electrical connection, and more particularly, to a terminal and a conductive panel assembly including the same.

Background

The electrical connection between a printed circuit board (hereinafter, abbreviated as PCB board) and an electrical device is generally achieved by a wiring terminal mounted on the PCB board and a wire harness connected to the electrical device. First, the connection terminals are mounted on the PCB board and fixed together with the PCB board by, for example, soldering and form an electrical connection, and then the conductive terminals of the wire harness are mounted on the connection terminals by screws, thereby achieving the electrical connection of the PCB board with the electrical equipment.

However, during installation, the conductive terminals may rotate due to, for example, forces during screwing in the screws, and thus sufficient force needs to be applied to inhibit such rotation to arrange the wire harness in a desired direction. In addition, when the wire harness to which the conductive terminal is connected is moved by an external force, the conductive terminal is also affected to rotate, which loosens the screw connection between the conductive terminal and the connection terminal and causes a risk of, for example, a virtual connection. The existing wiring terminal structure not only causes inconvenience in mounting the conductive terminal, but also reduces the reliability of the electrical connection between the wiring terminal and the conductive terminal.

Similar drawbacks exist in connection terminals for other types of conductive panels (e.g., conductive panels in switch cabinets, sockets, etc.). Accordingly, improvements in existing terminals and conductive panel assemblies are needed.

A connection terminal 100 according to an embodiment of the present application is described below with reference to fig. 1 to 3.

Fig. 1 illustrates a perspective view of a connection terminal 100 mounted on a conductive panel according to an exemplary embodiment of the present application, and fig. 2 illustrates a cross-sectional view of the connection terminal 100 mounted on the conductive panel according to an exemplary embodiment of the present application.

According to an exemplary embodiment of the present application, there is provided a connection terminal 100 for electrically connecting a wire harness with a conductive panel (e.g., PCB board) 200. As shown in fig. 1, the connection terminal 100 generally includes a connection portion 10 and a mounting portion 20. A threaded hole 111 is provided on the first face 10a of the connection portion 10, the threaded hole 111 being configured to engage with a screw so that an electrical connection is established between the conductive terminal of the wire harness and the connection portion 10. The mounting portion 20 extends from the connection portion 10 and is configured to mount the connection terminal 100 to the conductive panel 200 and establish an electrical connection with the conductive panel 200. At the time of mounting, first, a screw is inserted into the wiring portion of the conductive terminal, and the screw is screwed into the screw hole 111 to be fastened. At this time, the conductive terminal is tightly pressed against the end of the screw hole 111 by the screw, so that the conductive terminal of the wire harness and the connection portion 10 establish stable electrical connection. The conductive terminals may have various forms to be mated with the screws and the screw holes 111. In this way, an external current flows through the conductive terminals of the wire harness to the mounting portion 20 via the connection portion 10 and finally to the conductive panel 200, thereby forming an electrical connection of the conductive panel 200 with the outside.

It should be noted that although the technical concept of the present application is described herein by taking the screw hole 111 as an example, the present application is not limited thereto, but various detachable connection structures such as a bayonet, a socket, an elastic ring, a screw hole, etc. may be provided on the connection portion 10. Thus, in summary, a detachable connection structure is provided on the first face 10a of the connection portion 10, the detachable connection structure being configured such that the conductive terminals of the wire harness are electrically connected with the connection portion 10 through the detachable connection structure. In order to restrict rotation of the conductive terminal of the wire harness, according to an exemplary embodiment of the present application, a protruding portion 12 is provided on the first face 10a of the connection portion 10, the protruding portion 12 being configured to be able to restrict rotation of the conductive terminal by contact with the conductive terminal when the connection portion 10 is connected with the conductive terminal. For example, when the conductive terminal is subjected to an external force (e.g., a rotational force applied to the conductive terminal by a screw when the screw is screwed into the screw hole 111 or a force generated to the conductive terminal when the wire harness is moved by the external force), the conductive terminal may abut against the protruding portion 12 so as not to cause further rotation of the conductive terminal, so that a more stable electrical connection between the conductive terminal and the connection portion 10 is ensured. As another example, when the detachable connection structure is implemented as a socket, for example, the conductive terminal may be electrically connected with the connection part 10 by inserting a latch in the socket. In this case, when the wire harness of the conductive terminal is moved by an external force, the conductive terminal abuts against the protruding portion 12, thereby ensuring stable connection between the conductive terminal and the connection portion.

According to an exemplary embodiment of the present application, as shown in fig. 1, the protrusion 12 includes at least two protrusions 12', which protrude from the edge of the connection part 10. For convenience of manufacture, it is preferable that the protruding portion 12 is manufactured as a protrusion 12 'protruding at the edge of the connection portion 10, and the protrusion 12' can simply abut against the conductive terminal, thereby achieving the purpose of restricting the rotation of the conductive terminal. However, other forms of the projections 12 are also contemplated, for example, the projections 12 may be provided with a slot into which the conductive terminals may be snapped. Meanwhile, embodiments are also contemplated in which the protruding portion 12 is provided at other positions of the connection portion 10.

Preferably, in order to limit the rotation of the conductive terminal to the maximum, the conductive terminal is received between at least two protrusions 12'. In the case where only one protrusion 12 'is provided, the conductive terminal can be restricted from rotating in one direction while contacting the protrusion 12', but can be rotated at least once in the opposite other direction. That is, one protrusion 12' can solve the problem that the conductive terminal rotates with the screw during the installation, but does not solve the defect that the electrical connection between the installed conductive terminal and the connection part 10 is rotated loose due to the external force well. In an embodiment of the present application, it is therefore preferable to provide at least two protrusions 12 'and to receive the conductive terminal between the adjacent two protrusions 12', so as to limit the rotation of the conductive terminal to the maximum extent, in order to better ensure the electrical connection between the conductive terminal and the connection terminal 100.

As shown in fig. 1, according to an exemplary embodiment of the present application, at least two protrusions 12' include four protrusions 12', the connection part 10 is square, and the four protrusions 12' are disposed at four corners of the connection part 10, respectively. In order to increase the flexibility of use, it is preferable to provide more protrusions 12', for example, three, four or more. In an exemplary embodiment of the present application, four protrusions 12' are provided on the connection part 10, the four protrusions 12' being provided at four corners of the connection part 10, respectively, to provide four possible locations for receiving the conductive terminals (i.e., locations between every two adjacent protrusions 12 ').

Further, according to an exemplary embodiment of the present application, the height of the protrusion 12' is greater than the height of the conductive terminal. In order for the protrusion 12' to better restrict the rotation of the conductive terminal, the height of the conductive terminal is set smaller than the height of the protrusion 12', which can prevent the conductive terminal from rotating beyond the protrusion 12' when the external force is excessive.

As shown in fig. 1 and 2, according to an exemplary embodiment of the present application, the connection part 10 has an extension part 11 protruding from a second face 10b of the connection part 10 opposite to the first face 10a, and a screw hole 111 is provided in the extension part 11. By such a design, the length of engagement of the screw with the thread 110 of the threaded hole 111 can be increased, thereby reinforcing engagement of the screw with the threaded hole 111, making it more difficult for the mounted screw to rotate due to an external force, and consequently, fixing the conductive terminal more firmly on the connection portion 10 of the terminal 100.

According to an exemplary embodiment of the present application, the threaded hole 111 is a through hole that extends through the entire length of the extension 11. In general, since screws available on the market have different lengths, in order to increase the flexibility of use of the terminal 100 while ensuring the reliability of the connection, as described above, the length of the threaded hole 111 should be as long as possible (i.e., the extension 11 is provided) to accommodate the entire screw or at least to enable the screw to be completely screwed into the threaded hole 111 (i.e., a portion of the screw protrudes from the other end of the threaded hole 111 where the conductive terminal is not fixed). Therefore, it is preferable in this embodiment that the screw thread 110 extends over the entire length of the screw hole 111, and the screw hole 111 is a through hole penetrating the entire length of the extension 11. Alternatively, in other embodiments according to the application, the threaded bore 111 may not extend through the entire length of the extension 11 (i.e., the threaded bore 111 is a blind bore), as will be described in detail below with reference to fig. 3.

Fig. 3 illustrates a cross-sectional view of a connection terminal 100 mounted on a conductive panel 200 according to another exemplary embodiment of the present application.

According to another exemplary embodiment of the present application, as shown in fig. 3, the threaded bore 111 is a blind bore provided in a portion of the extension 11, so as to form a closed-bottom cavity 112' within the threaded bore 111. In the process of installing the screw, metal impurities such as electroplating slag, tin plating powder and the like fall on the surface of the conductive panel, so that electric sparks are easily caused when the screw is electrified, and the conductive panel is damaged. Accordingly, the cavity 112 'is provided to accommodate metal impurities, which may be dropped into and stored in the cavity 112' without being dropped on the surface of the conductive panel 200 during the mounting process, thereby ensuring the reliability of the conductive panel 200.

Although the foregoing embodiment solves the problem that the conductive terminal is rotated by an external force, since the height of the connection terminal 100 is excessively high, the rigidity of the mounting portion 20 is lowered, and when the conductive terminal is mounted (i.e., when the screw is screwed in), the mounting portion 20 is easily deformed to loose or even fail the connection with the conductive panel 200. Therefore, in order to solve this problem, according to an exemplary embodiment of the present application, the outer profile of the extension 11 is elliptical or polygonal, and is configured to be at least partially received in the receiving hole 202 (see fig. 5) of the conductive panel 200, the inner profile of the receiving hole 202 matching the outer profile of the extension 11. When the screw is screwed in, the extension 11 will abut against the inner contour of the receiving hole 202 and be able to withstand a portion of the torque, thereby reducing the torque experienced by the mounting portion 20 to prevent deformation of the mounting portion 20.

As described above, the mounting portion 20 is configured to mount the connection terminal 100 to the conductive panel 200 and establish electrical connection. To achieve this, as shown in fig. 1 to 3, a connection hole 201 is provided on the conductive panel 200 and the mounting part 20 includes a pin 21. According to an exemplary embodiment of the present application, the mounting part 20 is configured to be inserted into the connection hole 201 to establish an electrical connection between the mounting part 20 and the circuit of the conductive panel 200 exposed in the connection hole 201. In the present embodiment, the pins 21 may be fixedly connected to the conductive panel 200 by welding, but the present application is not limited thereto, and any known fixed connection method may be used.

The conductive panel assembly 300 according to another exemplary embodiment of the present application will be further described with reference to fig. 4 and 5. Fig. 4 illustrates a top side perspective view of a conductive panel assembly 300 according to another exemplary embodiment of the application; fig. 5 illustrates a bottom side perspective view of the conductive panel assembly 300 shown in fig. 4.

As shown in fig. 4, the conductive panel assembly 300 includes: a conductive panel (e.g., PCB board) 200; and the connection terminal 100 according to the foregoing embodiment. In the present exemplary embodiment, the mounting portion 20 of the connection terminal 100 includes only the pin 21, that is, the pin 21 directly extends from the connection portion 10. However, since the extension 11 has a length so as not to contact the conductive panel 200, as shown in fig. 5, a receiving hole 202 is further provided on the conductive panel 200 such that the extension 11 is received in the receiving hole 202 after the mounting portion 20 of the connection terminal 100 is inserted into the connection hole 201 of the conductive panel 200. By omitting other portions of the mounting portion 20 and providing the receiving hole 202 on the conductive panel 200, the connection portion 10 is closer to the conductive panel 200 so that the height of the connection terminal 100 is reduced, thereby reducing deformation of the mounting portion 20 during mounting, and preventing the mounting portion 20 from being failed.

The above-described embodiments of the present application provide a wiring terminal and a conductive panel assembly. According to the technical scheme of the application, the wiring terminal and the conductive panel assembly are provided with the additional protruding part at the connecting part, and the protruding part can contact with the conductive terminal of the wiring harness to limit the rotation of the conductive terminal, so that the conductive terminal cannot rotate when being subjected to external force, the conductive terminal is convenient to install, and meanwhile, the reliability of the electrical connection between the conductive terminal and the wiring terminal is enhanced, and the reliability of the use of the wiring terminal is improved.

The application has been described in detail with reference to specific embodiments thereof. It will be apparent that the embodiments described above and shown in the drawings are to be understood as illustrative and not limiting of the application. It will be apparent to those skilled in the art that various modifications or variations can be made in the present application without departing from the spirit thereof, and that such modifications or variations do not depart from the scope of the application.
