Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, and in particular to a terminal block for circuit boards. Background Technology

[0002] With the rapid development of electronic devices towards miniaturization, integration, and high performance, circuit boards, as core components of electronic devices, undertake the crucial task of connecting various electronic components and transmitting signals and electrical energy. In practical applications of circuit boards, terminals, as important interface components for achieving reliable electrical connections between circuit boards and external wires and equipment, directly affect the stability, safety, and ease of maintenance of the entire electronic device.

[0003] Currently, most existing terminal blocks are fixed to circuit boards by manual riveting to achieve a stable connection between the terminal blocks and the circuit board. However, due to factors such as the operator's skill level, fatigue level, and concentration level, it is difficult to ensure that the position of the rivet is completely consistent each time, and the deformation direction and degree of the rivet will be affected, which will lead to differences in the extension length of the terminal block.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a terminal block for circuit boards.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A terminal block for a circuit board includes a circuit board, copper terminals, and a terminal body; the copper terminals are disposed on the circuit board; the copper terminals are provided with a positioning part and a first limiting part that are fixed and limited by the circuit board; the terminal body is detachably connected to the circuit board; when the copper terminals are connected to the circuit board, the positioning part is inserted into the circuit board, and the contact surface of the first limiting part abuts against the contact surface of the circuit board.

[0008] As a further explanation, a plane is provided on one side of the positioning part, and it is arranged parallel to the axis of the copper terminal.

[0009] As a further explanation, the circuit board is provided with a connecting hole for the positioning part to be inserted; a locking surface corresponding to the plane is provided on one side of the connecting hole; when the positioning part is inserted into the connecting hole, the plane abuts against the locking surface.

[0010] As a further explanation, the positioning part is provided with a contact part that increases the riveting area; the contact part has a conical or arc-shaped structure.

[0011] As further explained, the first limiting part has a first protrusion extending outward; the outer diameter of the first protrusion is larger than the outer diameter of the positioning part.

[0013] As further explained, the copper terminal block is provided with a second limiting part on the side near the terminal body, and the second limiting part has a second protrusion extending outward; the outer diameter of the second protrusion is larger than the outer diameter of the positioning part.

[0014] As further explained, the second limiting part has a hexagonal or circular structure.

[0015] As further explained, a locking screw is provided between the terminal body and the copper terminal, and the copper terminal is provided with a threaded hole for the locking screw to be threadedly connected; a washer is provided between the locking screw and the terminal body.

[0016] As a further explanation, an insulating layer is provided between the circuit board and the first limiting part.

[0017] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] In one embodiment of this utility model, such as Figure 1-3 As shown, a terminal block for a circuit board is provided, including a circuit board 10, copper terminals 20, and a terminal body 30. The copper terminals 20 are disposed on the circuit board 10. The copper terminals 20 are provided with a positioning portion 21 and a first limiting portion 22 that are fixed and limited to the circuit board 10. The terminal body 30 is detachably connected to the circuit board 10. When the copper terminals 20 are connected to the circuit board 10, the positioning portion 21 is inserted into the circuit board 10, and the contact surface of the first limiting portion 22 abuts against the contact surface of the circuit board 10.

[0033] In this embodiment, the terminal body 30 includes a connecting portion and a terminal portion. The connecting portion is located on the side of the copper terminal 20 away from the first limiting portion 22 (i.e., on the second limiting portion 23 of the copper terminal 20), and the connecting portion is detachably connected to the copper terminal 20, such as by screw connection, plug connection, or other detachable connection methods.

[0034] By setting a positioning part 21, when the positioning part 21 is inserted into the connecting hole 11, the plane 211 on one side of the positioning part 21 abuts against the locking surface 12 in the circuit board 10, ensuring that the position of the copper terminal 20 is consistent each time it is installed, avoiding positioning deviations caused by manual operation factors during manual riveting. At the same time, by setting a first limiting part 22, the contact surface of the first limiting part 22 abuts against the contact surface of the circuit board 10, forming an effective limiting structure to prevent the copper terminal 20 from shifting towards the circuit board 10 side due to external force after riveting, thereby ensuring the consistency of the extension length of the terminal.

[0035] Preferably, the positioning part 21 has a flat surface 211 on one side, which is parallel to the axis of the copper terminal 20. The circuit board 10 has a connecting hole 11 for the positioning part 21 to be inserted. A locking surface 12 corresponding to the flat surface 211 is provided on one side of the connecting hole 11. When the positioning part 21 is inserted into the connecting hole 11, the flat surface 211 abuts against the locking surface 12. By setting the flat surface 211 and the locking surface 12, and by the contact between the flat surface 211 and the locking surface 12, the positioning accuracy is further enhanced, preventing slight displacement of the copper terminal 20 during the riveting process. This effectively eliminates the problem of inconsistent deformation direction and degree of the rivet due to positioning deviation during manual riveting, thereby ensuring the accuracy and consistency of the terminal extension length.

[0036] Furthermore, the positioning part 21 is provided with a contact part 24 to increase the riveting area. The contact part 24 has a conical or arc-shaped structure. By providing the contact part 24, the riveting area with the circuit board 10 is increased, making the riveting force more evenly distributed, reducing uneven deformation of the rivet caused by local stress concentration, and thus ensuring the stability and reliability of the extension length of the terminal block.

[0037] Preferably, the first limiting part 22 has an outwardly extending first boss. The outer diameter of the first boss is larger than the outer diameter of the positioning part 21. By setting the outer diameter of the first boss to be larger than the outer diameter of the positioning part 21, an effective mechanical limit is formed, preventing the copper terminal 20 from shifting towards the circuit board 10 due to external force after riveting. This not only enhances the structural stability of the terminal but also avoids changes in the extension length of the terminal caused by the displacement of the copper terminal 20, thus improving the overall quality of the product.

[0038] Furthermore, the first limiting part 22 has a hexagonal or circular structure. By setting the first limiting part 22 to a hexagonal or circular structure, it facilitates the clamping and rotation of the copper terminal 20 when its position needs adjustment. Furthermore, if a hexagonal structure is used, it can be correspondingly fitted and fixed to the circuit board 10, effectively preventing displacement of the copper terminal 20 and further avoiding changes in the extension length of the terminal caused by the displacement of the copper terminal 20.

[0039] Preferably, the copper terminal 20 has a second limiting portion 23 on the side near the terminal body 30, and the second limiting portion 23 has a second protrusion extending outward. The outer diameter of the second protrusion is larger than the outer diameter of the positioning portion 21. By providing the second limiting portion 23 and the second protrusion, the contact area between the terminal body 30 and the copper terminal 20 is increased, the connection stability between the terminal body 30 and the copper terminal 20 is improved, and the vibration resistance and impact resistance of the terminal are enhanced.

[0040] Furthermore, the second limiting part 23 has a hexagonal or circular structure. The hexagonal or circular structure of the second limiting part 23 facilitates the clamping and rotation of the copper terminal 20 with the tool when the position needs to be adjusted.

[0041] Preferably, a locking screw 31 is provided between the terminal body 30 and the copper terminal 20, and the copper terminal 20 is provided with a threaded hole 25 for threaded connection of the locking screw 31. A washer 32 is provided between the locking screw 31 and the terminal body 30. The detachable connection between the locking screw 31 and the threaded hole 25 facilitates the installation and replacement of the terminal body 30, improves the replacement efficiency of the terminal body 30, and the washer 32 enhances the tightness and sealing of the connection.

[0042] Preferably, an insulating layer 13 is provided between the circuit board 10 and the first limiting part 22, wherein the insulating layer 13 can be made of insulating materials such as epoxy resin and polytetrafluoroethylene. By providing the insulating layer 13, current is effectively isolated, preventing short circuits and leakage, and improving the electrical safety performance of the terminals.

[0043] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
