Description

Technical Field

[0001] This utility model relates to electrical connectors, and in particular to a clip-on terminal used on heating inserts. Background Technology

[0002] Terminals are a common type of accessory used to achieve electrical connections. They are also frequently used for the electrical connection of heating elements, such as the heating system of automotive rearview mirrors. These terminals have specific specifications and performance requirements to ensure that current can be transmitted effectively and to guarantee safe use.

[0003] Currently, heating elements and terminals are typically connected using screws, welding, or crimping. Welding is a cumbersome process that makes subsequent maintenance and replacement difficult. Screws or crimping can easily cause the heating elements to loosen or even fall off during prolonged use, making it difficult to ensure the stability of current delivery and the safety of the product. Utility Model Content

[0004] The purpose of this invention is to provide a clip-on terminal for use on heating inserts to solve the technical problems in the prior art. It can quickly fix the heating inserts on the terminal and make the connection between the heating inserts and the terminal more secure.

[0005] This utility model provides a clip-on terminal for use on a heating insert, including a terminal body and a connecting unit disposed at the end of the terminal body for connecting the heating insert to the terminal body. The connecting unit includes a flattening component and a positioning component. The flattening component enables the heating insert to fit against the terminal body, while driving the positioning component to limit the heating insert. A fixing unit disposed at the end of the terminal body away from the connecting unit is used to fix the core wire to the terminal body.

[0006] Preferably, the flattening assembly includes a functional section disposed at the end of the terminal body, the functional section being horizontally positioned, and the size of the functional section being larger than the size of the heating insert. This ensures the stability of the heating insert during connection.

[0007] Preferably, the device further includes symmetrically bent portions on both sides of the functional section, the total dimension of the two sets of bent portions being smaller than the dimension of the functional section. This allows for the combination of the heating insert and the terminal.

[0008] Preferably, the positioning component includes multiple sets of connecting ports symmetrically arranged on the bent portion. The bent portion has a protrusion connected to the connecting port on the side near the functional part, and the functional part has a recessed hole matching the protrusion on the side near the bent portion. When the bent portion and the functional part are parallel, the protrusion and the recessed hole engage, and the protrusion is semi-circular in shape. This provides a limiting effect on the assembled heating insert, thereby improving the firmness between the heating insert and the terminal.

[0009] Preferably, the device further includes a piercing portion disposed on the side of the functional part near the bending portion. The piercing portion is arc-shaped and located between the recesses on both sides. When the bending portion and the functional part are parallel to each other, the piercing portion is in contact with the bending portion. This further improves the stability of the connection between the heating insert and the terminal.

[0010] Preferably, the fixing unit includes a rivet wire sheath and a rivet wire core foot disposed at the end of the terminal body away from the functional part. The rivet wire core foot is located between the rivet wire sheath and the terminal body, and both the rivet wire sheath and the rivet wire core foot have a U-shaped structure. By fixing the connection between the core wire and the terminal, and between the core wire and the terminal on the side near the heating insert, displacement of the core wire during use can be avoided, thereby improving the stability of current transmission.

[0011] Preferably, the rivet core foot has multiple sets of anti-slip lines, which are perpendicular to the direction of the terminal body. By increasing the friction between the core wire and the terminal, slippage between the core wire and the terminal is reduced, ensuring stable power transmission while reducing wear on the core wire.

[0012] Compared with the prior art, this utility model can quickly fix the heating insert onto the terminal and make the connection between the heating insert and the terminal more secure. Attached Figure Description

Therefore, they should not be construed as limitations on the embodiments of this application.

[0026] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0027] like Figures 1-5 As shown, an embodiment of this utility model provides a clip-on terminal for use on a heating insert, including a terminal body 1. The specific structure of the terminal body 1 can be referred to in the prior art, which is known to those skilled in the art and will not be described in detail here. It also includes: a connecting unit disposed at the end of the terminal body 1 for connecting the heating insert to the terminal body 1, wherein the connecting unit includes a flattening component and a positioning component. The flattening component can make the heating insert fit against the terminal body 1, and at the same time drive the positioning component to limit the heating insert; a fixing unit disposed at the end of the terminal body 1 away from the connecting unit for fixing the core wire to the terminal body 1.

[0028] In the embodiments provided in this application, the flattening component includes a functional part 5 disposed at the end of the terminal body 1. The functional part 5 is horizontally disposed and its size is larger than that of the heating insert.

[0029] The functional part 5 and the terminal body 1 can adopt an integral molding structure to ensure the stability of the terminal. The horizontal setting of the functional part 5 can reduce the gap between the terminal and the heating plate when the heating plate is connected to the terminal, thereby improving the stability of the connection between the heating plate and the terminal.

[0030] In the embodiments provided in this application, there are also bent portions 6 that are symmetrically bent on both sides of the functional portion 5, and the total size of the two sets of bent portions 6 is smaller than the size of the functional portion 5.

[0031] The bending part 6 has a certain degree of plasticity. The bending part 6 and the functional part 5 are integrally formed, and the connection between the bending part 6 and the functional part 5 is arc-shaped, so as to bend the bending part 6 towards one side of the functional part 5 and ensure the stability of the bending.

[0032] In the embodiments provided in this application, the positioning component includes multiple sets of connecting ports 7 symmetrically opened on the bending portion 6. A protrusion 8 connected to the connecting port 7 is provided on the side of the bending portion 6 near the functional portion 5. A concave hole 9 matching the protrusion 8 is provided on the side of the functional portion 5 near the bending portion 6. When the bending portion 6 is parallel to the functional portion 5, the protrusion 8 and the concave hole 9 cooperate, and the protrusion 8 is semi-circular.

[0033] The protrusion 8 and the connection port 7 are connected by a detachable method, such as screws, so that the protrusion 8 can be replaced in time if it is worn or damaged, thus ensuring the stability of the connection between the heating plate and the terminal.

[0034] In the embodiments provided in this application, a puncture portion 10 is provided on the side of the functional part 5 near the bending portion 6. The puncture portion 10 is arc-shaped and located between the recesses 9 on both sides. When the bending portion 6 and the functional part 5 are parallel to each other, the puncture portion 10 is in contact with the bending portion 6.

[0035] Compared to simply connecting the heating insert and the terminal through the bending part 6, the piercing part 10 can improve the connection effect between the heating insert and the terminal.

[0036] In the embodiments provided in this application, the fixing unit includes a rivet foot 2 and a rivet core foot 3 disposed at the end of the terminal body 1 away from the functional part 5. The rivet core foot 3 is located between the rivet foot 2 and the terminal body 1, and both the rivet foot 2 and the rivet core foot 3 have a U-shaped structure. Multiple sets of anti-slip lines 4 are provided on the rivet core foot 3, and the anti-slip lines 4 are perpendicular to the direction of the terminal body 1.

[0037] The connection between the terminal and the core wire, as well as the part of the core wire located inside the terminal, can be fixed by the rivet foot 2 and the rivet core foot 3, thereby reducing the wear between the core wire and the terminal. On the one hand, it can avoid friction between the core wire and the heating plate, which affects the stability of the connection. On the other hand, it can reduce the wear between the core wire and the terminal, thereby extending the service life of the core wire and improving its safety in use.

[0038] The method of using this utility model is as follows: The heating insert is inserted between the piercing part 10 and the bending part 6. Then, the bending part 6 is pressed towards the heating insert using a mold device. This allows the bending part 6 and the piercing part 10 to combine with the heating insert, while the protrusion 8 is locked in the concave hole 9. This provides a limiting effect for the connected heating insert, preventing it from shifting during use and ensuring its performance. In addition, the core wire for electrical connection of the heating insert is fixed in the terminal by the rivet foot 2 and the rivet core foot 3. The stability of the core wire during use is ensured by fixing it in multiple places.

[0039] The above description is only a preferred embodiment of the present utility model. However, the scope of the present utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of the present utility model.
