Description

Technical Field

[0001] The invention relates to an interlocking terminal. Background Art

[0002] Terminal connectors are widely used as electrical connection parts and are often used in engines and other environments with strong vibration, high temperature, high corrosion, etc.

[0003] The existing connection method is to use an ordinary ring terminal, install it on the screw, and then fix it with a gasket and screws. High vibration environment can easily cause the connector connection to loosen and deform, causing the engine to stop working or other damage, and also cause friction at the connection part to damage the plating, which will cause the connection part to oxidize or corrode quickly, and then cause the engine to stop working or be damaged. The connection operation of the existing terminal connector is also cumbersome and error-prone. A more reliable terminal connector is urgently needed in the market. Summary of the invention

[0004] In view of the background technology, the present invention aims to provide an interlocking terminal with long service life and reliable connection, comprising a stator locking block and a wire connector.

[0005] The stator locking block is a columnar body, one end of which is a mounting head provided with a screw hole, and the other end is a docking head for a screwdriver or a wrench. A circular groove is provided on the periphery of the mounting head for connecting a wire connector.

[0006] The wire connector comprises a wire fixing section and a locking block installation section.

[0007] One end of the wire fixing section is a wire covering head, and the other end is connected to the locking block installation section.

[0008] The locking block installation section is U-shaped as a whole, and includes an upper installation section, a lower connection section and a bow-shaped connection section. The upper installation section and the lower connection section are arranged in parallel and spaced apart, and are connected by the bow-shaped connection section at one end away from the wire fixing section, and the other end of the lower connection section is bent toward the upper installation section and connected to the locking block installation section, and the upper installation section extends toward the locking block installation section and exceeds the position where the lower connection section is connected to the locking block installation section.

[0009] The upper mounting section is provided with a circular hole facing the lower connecting section, the diameter of the circular hole is between the outer diameter of the mounting head and the diameter of the circular groove. The lower connecting section is provided with a clearance hole corresponding to the circular hole, the diameter of the clearance hole is larger than the screw hole diameter of the stator locking block.

[0010] The mounting head of the stator locking block is mounted on the locking block mounting section of the wire connector through the circular groove and the circular hole.

[0011] When in use, align the screw hole of the mounting head with the stud on the stator of the fuel pump, screw it in, and tighten it with a wrench or a screwdriver. When tightening, since the locking block mounting section is between the stator locking block and the quasi-fuel pump stator, the stator locking block squeezes the locking block mounting section, and the distance between the upper mounting section and the lower connecting section is reduced, the locking block mounting section is elastically deformed, and plays the role of an elastic gasket. At the same time, the locking block mounting section can also absorb a certain amount of vibration generated by the quasi-fuel pump, thereby reducing the influence of the vibration on the electronic components connected to the wire connector.

[0012] Preferably, the wire connector is formed by bending a whole piece of material, has strong integrity and is not easy to break.

[0013] Preferably, the screw hole runs through the entire stator locking block.

[0014] Preferably, the butt joint of the stator locking block is cylindrical. The mounting head is a truncated cone, and the end with a smaller diameter is connected to the butt joint. The diameter of the butt joint is larger than the outer diameter of the mounting head. The end surface of the butt joint and the peripheral surface of the mounting head form the circular groove.

[0015] Preferably, the docking joint and the mounting head are made of a whole piece of material or connected by welding. When integrally formed, the low temperature can be used to produce shrinkage, thereby reducing the size of the mounting head so as to fit into the round hole.

[0016] Preferably, the wire fixing section of the wire connector is provided with a wire covering groove, and the side of the wire covering groove is provided with symmetrical wrapping angles. When the wire is placed in the wire covering groove, the wire covering groove and the wrapping angle are bent to compress the wire.

[0017] Preferably, the upper mounting section extends toward the locking block mounting section and is in close contact with an opposite side of the locking block mounting section.

[0018] Preferably, a side portion of the locking block mounting section is provided with a covering folded edge corresponding to the upper mounting section, and the covering folded edge presses the end of the upper mounting section onto the locking block mounting section.

[0019] Preferably, an arc-shaped bending groove is provided on the inner side of the portion where the bow-shaped connecting section is connected to the upper mounting section and the lower connecting section. When the upper mounting section and the lower connecting section are bent, the arc-shaped bending groove at the bending point has a giving way effect, thereby preventing material extrusion at the bending point due to bending, resulting in bending marks, and further stress concentration marks, which are easy to break.

[0020] The beneficial effects of the present invention are:

[0021] 1. The stator locking block and the wire connector are movably connected to reduce the rigidity of the product and absorb certain vibrations during operation;

[0022] 2. The locking block installation section has a certain elasticity, which acts as an elastic gasket and can also absorb vibration;

[0023] 3. The upper installation section and the lower connection section of the locking block installation section are connected by a bow-shaped connection section, and the connection has an arc-shaped bending groove, which can reduce stress concentration and avoid fracture of the connection.

DETAILED DESCRIPTION

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] See also Figures 1 to 6 , an interlocking terminal comprises a stator locking block 1 and a wire connecting piece 2.

[0035] The stator locking block 1 is a columnar body, one end of which is a mounting head 11 with a screw hole 111, and the other end is a docking head 12 for a screwdriver or a wrench. A circular groove 112 is provided on the periphery of the mounting head 11 for connecting the wire connector 2. In this embodiment, the docking head 12 of the stator locking block 1 is cylindrical. The mounting head 11 is a truncated cone, and the end with a smaller diameter is connected to the docking head 12. The diameter of the docking head 12 is larger than the outer diameter of the mounting head 11. The end face of the docking head 12 and the circumferential surface of the mounting head 11 form the circular groove 112. The docking head 12 and the mounting head 11 are made of a whole piece of material. In other embodiments, the mounting head 11 and the docking head 12 can also be connected by welding.

[0036] The wire connector 2 includes a wire fixing section 21 and a locking block installation section 22 .

[0037] One end of the wire fixing section 21 is a wire covering head, and the other end is connected to the locking block installation section 22. In this embodiment, the wire fixing section 21 is provided with a wire covering groove 211, and the side of the wire covering groove 211 is provided with a symmetrical covering angle 212. When the wire is placed in the wire covering groove 211, the wire covering groove 211 and the covering angle 212 are bent to compress the wire.

[0038] The locking block mounting section 22 is U-shaped as a whole, and includes an upper mounting section 221, a lower connecting section 222 and an arch-shaped connecting section 223. The upper mounting section 221 and the lower connecting section 222 are arranged in parallel and spaced apart, and are connected by the arch-shaped connecting section 223 at one end away from the wire fixing section 21, and the other end of the lower connecting section 222 is bent toward the upper mounting section 221 and connected to the locking block mounting section 22, and the upper mounting section 221 extends toward the locking block mounting section 22 and exceeds the position where the lower connecting section 222 is connected to the locking block mounting section 22. In this embodiment, the upper mounting section 221 extends toward the locking block mounting section 22 and is in close contact with the opposite side of the locking block mounting section 22. The side of the locking block mounting section 22 is provided with a covering folded edge 213 corresponding to the upper mounting section 221, and the covering folded edge 213 presses the end of the upper mounting section 221 onto the locking block mounting section 22.

[0039] In order to improve the strength of the wire connector 2, the wire connector 2 is formed by bending a whole piece of material, which has strong integrity and is not easy to break. The inner side of the part where the bow-shaped connecting section 223 is connected with the upper mounting section 221 and the lower connecting section 222 is provided with an arc-shaped bending groove. When the upper mounting section 221 and the lower connecting section 222 are bent, the arc-shaped bending groove at the bending part has a yielding effect, preventing the bending part from being squeezed by the material due to the bending, resulting in bending marks, and then stress concentration marks, which are easy to break.

[0040] The upper mounting section 221 is provided with a circular hole facing the lower connecting section 222, and the diameter of the circular hole is between the outer diameter of the mounting head 11 and the diameter of the circular groove 112. The lower connecting section 222 is provided with a clearance hole corresponding to the circular hole, and the diameter of the clearance hole is larger than the diameter of the screw hole 111 of the stator locking block 1.

[0041] The mounting head 11 of the stator locking block 1 shrinks due to low temperature, and the mounting head 11 is reduced so as to fit into the round hole, and the stator locking block 1 is mounted on the locking block mounting section 22 of the wire connector 2 .

[0042] See also Figure 7 and Figure 8 When in use, align the screw hole 111 of the mounting head 11 with the stud on the stator 3 of the fuel pump, screw it in, and tighten it with a wrench or a screwdriver. When tightening, since the locking block mounting section 22 is between the stator locking block 1 and the quasi-fuel pump stator 3, the stator locking block 1 squeezes the locking block mounting section 22, and the distance between the upper mounting section 221 and the lower connecting section 222 is reduced, the locking block mounting section 22 is elastically deformed, and plays the role of an elastic gasket. At the same time, the locking block mounting section 22 can also absorb a certain amount of vibration generated by the quasi-fuel pump, thereby reducing the influence of the vibration on the electronic components connected to the wire connector 2.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it should be understood by those skilled in the art that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
