Description

Technical Field

[0001] This utility model relates to a rapid assembly device for wires, specifically a rapid assembly device for terminals and wires, belonging to the technical field of wire harness installation process equipment. Background Technology

[0002] A terminal is a wiring end, also called a wiring terminal, mainly used to transmit electrical signals or conduct electricity. A wire harness terminal, also called a wire harness connector, generally includes a plug and a socket, and is used for connecting wire harnesses to wire harnesses or wire harnesses to electrical components.

[0003] During wire harness assembly, the wires must first be connected to the wire harness terminals, and then the wire harness terminals are connected to mating wire harness terminals to form the complete wire harness. The connection between the wires and the wire harness terminals mainly includes crimp connections, solder connections, threaded connections, and piercing connections. Among these, the crimp connection method involves removing the insulation sleeve from the wire end and inserting it into the wire connection hole of the terminal, then clamping the wire using a terminal spring or clamp. The crimp connection method offers good mechanical strength and electrical continuity, making it suitable for high-current applications. For easy and quick connection, wire harness terminals using the crimp connection method typically include a built-in clamp with a compression spring and a corresponding wire connection hole. Pressing the button on the wire harness terminal overcomes the spring force to open the clamp; inserting the wire into the wire connection hole of the wire harness terminal and releasing the button closes the clamp to secure the wire. Currently, most wire harness assembly lines are assembled manually. For wire harness terminals that use crimping connection, manual operation not only has the problem of low efficiency, but also has the problem of insufficient pressing or damage to the clamp conductor due to operator fatigue. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides a quick assembly device for terminals and wires. For the installation and connection process of wire harness terminals and wires with built-in clamps, it can achieve quick installation and connection of terminals and wires without damaging the clamp conductor.

[0005] To achieve the above objectives, this quick assembly device for terminals and wires includes a base, a terminal slot, and a push-button assembly.

[0006] The terminal slots provided on the base are groove structures that match the external dimensions of the wire harness terminals;

[0007] The push-button assembly includes a telescopic push-button head and a push-button head telescopic control component; the telescopic push-button head extends into the terminal slot and is perpendicular to the push-button of the wire harness terminal; the push-button head telescopic control component is mounted on the base and the telescopic end of the push-button head telescopic control component is connected to the telescopic push-button head.

[0008] As a further improvement of this utility model, the inner surface of the terminal slot on one side parallel to the telescopic pressing head is a terminal positioning reference surface that mates with the side end face of the wire harness terminal. A terminal clamping assembly is provided on the inner surface of the other side of the terminal slot corresponding to the terminal positioning reference surface. The terminal clamping assembly includes a telescopic clamping head whose telescopic direction is perpendicular to the terminal positioning reference surface and a clamping head telescopic control mechanism that is pulsatorically connected to the telescopic clamping head. The telescopic clamping head is slidably mounted on the base.

[0009] As a further improvement of this utility model, the clamping head telescopic control mechanism is a normally open structure that keeps the telescopic clamping head in a retracted state in the initial state.

[0010] As a further improvement of this utility model, the press head telescopic control component is a normally open structure that keeps the telescopic press head in a retracted state in the initial state; the base is also provided with a micro-motion limit switch, the limit contact of the micro-motion limit switch extends into the terminal slot, and the swing stroke of the limit contact is matched with the wire harness terminal. The micro-motion limit switch is electrically connected to the clamping head telescopic control mechanism, and the micro-motion limit switch is electrically connected to the press head telescopic control component through a time delay relay.

[0011] As a further improvement of this utility model, the press head telescopic control component is installed on the base through a height positioning adjustment mechanism and a translation positioning adjustment mechanism.

[0012] As a further improvement of this utility model, for an integrated wire harness terminal with multiple side-by-side blocks arranged in a terminal block shape, the block pressing components are arranged in multiple groups side-by-side.

[0013] Compared with existing technologies, this quick assembly device for terminals and wires allows operators to first insert the wire harness terminal into the terminal slot, then control the extension and retraction control component of the pressing head to extend the pressing head. The extending pressing head presses against the pressing block of the wire harness terminal, opening the clamp built into the wire harness terminal. The operator then inserts the wire into the wire connection hole of the wire harness terminal, and then controls the extension and retraction control component of the pressing head to retract and reset the pressing head. The clamp closes and clamps the wire, and the wire harness terminal with the wire installed can be removed from the terminal slot. For integrated wire harness terminals with multiple side-by-side pressing blocks and an overall terminal block shape, only a terminal slot of suitable size needs to be set, and multiple sets of pressing block components need to be set to correspond to the pressing block positions to achieve simultaneous control of the opening and closing of multiple side-by-side clamps. The operation is simple, convenient, and quick, and can achieve rapid installation and connection of terminals and wires without damaging the clamp conductor. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figures 1 to 3 As shown, this quick assembly device for terminals and wires includes a base 1, a terminal slot 2, and a push-button assembly 3.

[0020] The terminal slot 2 provided on the base 1 is a groove structure that matches the outer dimensions of the wire harness terminal, and the wire harness terminal can be snapped and positioned in the terminal slot 2.

[0021] The pressing assembly 3 includes a telescopic pressing head 31 and a pressing head telescopic control component 32. The telescopic pressing head 31 extends into the terminal slot 2 and is perpendicular to the pressing block of the wire harness terminal. The pressing head telescopic control component 32 is mounted on the base 1, and the telescopic end of the pressing head telescopic control component 32 is connected to the telescopic pressing head 31. The pressing head telescopic control component 32 can be a telescopic cylinder structure such as a pneumatic cylinder, hydraulic cylinder, or electric cylinder, or it can be other linear reciprocating transmission structures such as a gear and rack structure with a drive motor. By controlling the action of the pressing head telescopic control component 32, the telescopic action of the telescopic pressing head 31 can be controlled, thereby enabling the pressing head 31 to press the pressing block of the wire harness terminal when the wire harness terminal is inserted into the terminal slot 2.

[0022] When using this quick assembly device for terminals and wires, the operator can first insert the wire harness terminal into the terminal slot 2, and then control the extension and retraction control component 32 to extend the extension and retraction control head 31. The extension and retraction control head 31 presses against the button block of the wire harness terminal, causing the clamp built into the wire harness terminal to open. Then, the operator inserts the wire into the wire connection hole of the wire harness terminal, and then controls the extension and retraction control component 32 to retract and reset the extension and retraction control head 31. The clamp then closes and clamps the wire, and the wire harness terminal with the wire installed can be removed from the terminal slot 2. For integrated wire harness terminals with multiple side-by-side button blocks and an overall terminal block shape, it is only necessary to set a terminal slot 2 of appropriate size and set multiple sets of button pressing components 3 corresponding to the button block positions. Figure 1 , Figure 2 As shown, the three sets of pressing components 3) can simultaneously control the opening and closing of multiple clamps set side by side, making the operation simple, convenient and quick.

[0023] To achieve accurate positioning of the wire harness terminal within the terminal slot 2, as a further improvement of this invention, the inner surface of one side of the terminal slot 2, parallel to the telescopic pressing head 31, serves as a terminal positioning reference surface that mates with the side end face of the wire harness terminal. A terminal clamping assembly 4 is provided on the inner surface of the other side of the terminal slot 2 corresponding to the terminal positioning reference surface. The terminal clamping assembly 4 includes a telescopic clamping head 41 whose telescopic direction is perpendicular to the terminal positioning reference surface, and a clamping head telescopic control mechanism 42 that is pulsatorically connected to the telescopic clamping head 41. The telescopic clamping head 41 is slidably mounted on the base. On body 1, the clamping head extension control mechanism 42 can be an electromagnetic control structure including an electromagnet or a pneumatic control mechanism including a drive cylinder. By controlling the action of the clamping head extension control mechanism 42, the extension and retraction of the telescopic clamping head 41 can be realized. Before the wire harness terminal is inserted into the terminal slot 2, the clamping head extension control mechanism 42 can be controlled to retract the telescopic clamping head 41. After the wire harness terminal is inserted into the terminal slot 2, the clamping head extension control mechanism 42 can be controlled to extend the telescopic clamping head 41, so that the telescopic clamping head 41 can be securely positioned and clamped. To simplify operation, the clamping head extension control mechanism 42 is a normally open structure that allows the telescopic clamping head 41 to be in the retracted state in the initial state. In the initial state, the telescopic clamping head 41 is in the retracted state. After the wire harness terminal is inserted into the terminal slot 2, the clamping head extension control mechanism 42 can be controlled to extend the telescopic clamping head 41, so that the telescopic clamping head 41 can be securely positioned and clamped. To further achieve automated operation, the press head extension control component 32 is a normally open structure that allows the telescopic press head 31 to be in a retracted state in the initial state. The base 1 is also equipped with a micro-switch 5. The travel contact of the micro-switch 5 extends into the terminal slot 2, and the swing travel of the travel contact matches the wire harness terminal. The micro-switch 5 is electrically connected to the clamping head extension control mechanism 42. The micro-switch 5 is electrically connected to the press head extension control component 32 via a time delay relay. When the wire harness terminal is inserted into the terminal slot 2, the micro-switch travel... When the travel contact of switch 5 swings and closes, the clamping head extension control mechanism 42 is first energized, causing the extension clamping head 41 to extend and securely position and clamp the wire harness terminal. Then, the pressing head extension control component 32 is energized, causing the extension pressing head 31 to press the button of the wire harness terminal. After the wire is inserted, the operator issues a command, and the pressing head extension control component 32 is first de-energized, causing the extension pressing head 31 to reset. Then, the clamping head extension control mechanism 42 is de-energized, causing the extension clamping head 41 to reset. The wire harness terminal with the wire installed can then be removed from the terminal slot 2.

[0024] To achieve versatility for wire harness terminals of different specifications, as a further improvement of this utility model, the press head telescopic control component 32 is mounted on the base 1 through a height positioning adjustment mechanism and a translational positioning adjustment mechanism. The height positioning adjustment mechanism can be a positioning pin and positioning hole structure that are matched, or a vertically set telescopic cylinder structure or other lifting positioning adjustment structures. The translational positioning adjustment mechanism can be a positioning pin and positioning hole structure that are matched, or a horizontally set telescopic cylinder structure or other translational positioning adjustment structures. For wire harness terminals of different specifications, the height position of the telescopic press head 31 and its horizontal position relative to the terminal positioning reference surface can be adjusted by controlling the height positioning adjustment mechanism and the translational positioning adjustment mechanism, thereby achieving versatility.
