An FPC harness with reversible deformation

Abstract

This utility model discloses a reversibly deformable FPC wire harness, including an interconnected connector assembly and a reversibly deformable FPC assembly. The connector assembly includes a pin socket, pins mounted through the pin socket, and a symmetrically arranged and interconnected lower and upper connector covers. The reversibly deformable FPC assembly includes a wavy FPC with a gold finger solder pad on one end of its upper surface, and an elastic silicone wrapped around the FPC with the gold finger solder pad exposed at the other end. This utility model effectively replaces the rubber-wrapped wire structure in the prior art by encasing the wavy FPC inside the elastic silicone, thus significantly increasing the integration of the wire harness transmission. Furthermore, the elastic silicone deforms under external force, and the wavy FPC deforms synchronously. When the external force is removed, the elastic silicone and FPC can return to their original shape and size, thereby effectively increasing the tensile strength and plasticity of the FPC wire harness.

Description

Technical Field

[0001] This utility model relates to the field of flexible printed circuit board technology, and in particular to an FPC wire harness with reversible deformation. Background Technology

[0002] A wire harness is a combination of multiple wires or cables bound together, typically used to transmit power, signals, or data from one device to another.

[0003] In the existing technology, wire harnesses transmit electrical energy or signals by wrapping wires (such as copper wires, aluminum wires, etc.) with rubber. This structure has the disadvantages of poor wire harness integration, poor toughness and plasticity. When subjected to external force, it is easy to be damaged, resulting in interruption of power, signal or data transmission, and the replacement cost is high. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an FPC harness with reversible deformation, including interconnected connector assemblies and reversible FPC assemblies;

[0005] The connector assembly includes a pin socket, a pin mounted through the pin socket, and a connector lower cover and a connector upper cover symmetrically arranged and connected to each other. The pin socket is fixed to the inner side of the connector lower cover, and the pin socket and the pin are located between the connector lower cover and the connector upper cover after connection. The front end of the connector lower cover and the connector upper cover after connection has a front port that exposes the pin and the rear end has a rear port that connects to the reversible deformable FPC assembly.

[0006] The reversible deformable FPC assembly includes a wavy FPC with a gold finger bonding pad on one upper side of the FPC, and an elastic silicone wrapped around the FPC with the end of the FPC having the gold finger bonding pad exposed.

[0007] The gold finger soldering pad is located inside the lower and upper covers of the connector after connection, and the pin is soldered to the gold finger soldering pad at one end of the rear port, and one end of the elastic silicone is locked inside the rear port.

[0008] Furthermore, the lower cover of the connector is provided with lower cover side ears on both the left and right sides, and the upper cover of the connector is provided with upper cover side ears on both the left and right sides. When the lower cover of the connector is connected to the upper cover of the connector, the front and rear ends of the lower cover side ears and the upper cover side ears on both sides are respectively engaged by the two sets of first fixing buckles and second fixing buckles on the left and right sides, and the sides are locked by the first fixing bolts respectively. The upper and lower parts are locked by the second fixing bolts in conjunction with the locking holes on the lower cover and the upper cover of the connector. The first fixing bolts are also used to fix the connector assembly to other equipment or mechanisms.

[0009] Furthermore, silicone clamping elements are provided on the inner side of the rear port of both the lower and upper connector covers to clamp and fix the elastic silicone extending into the rear port, thereby improving the tensile strength of the FPC harness.

[0010] Furthermore, one side of the wavy FPC is bonded with a conformal high-strength nylon fabric to improve the tensile strength of the FPC.

[0011] Furthermore, on the lower side of one end of the FPC with the gold finger solder pad, a first pressure-sensitive adhesive, a reinforcing sheet, and a second pressure-sensitive adhesive are sequentially attached to the corresponding gold finger solder pad. The first pressure-sensitive adhesive, the reinforcing sheet, and the second pressure-sensitive adhesive are all located inside the lower cover and upper cover of the connector after connection, and the other side of the second pressure-sensitive adhesive is attached to the inner side of the lower cover of the connector.

[0012] Through the above technical solution, this utility model effectively replaces the rubber-wrapped wire structure in the prior art by wrapping the wavy FPC inside the elastic silicone, thereby effectively increasing the integration of wire harness transmission; and the elastic silicone deforms when subjected to external force, and the wavy FPC deforms simultaneously. When the external force is removed, the elastic silicone and FPC can return to their original shape and size, thereby effectively increasing the tensile toughness and plasticity of the FPC wire harness.
