Problems solved by technology

[0002] In an existing flat cable with a connector, generally the width of the connector is greater than that of the flat cable. In this way, if the core wires of the cut flat cable are the same length and connected to the connector (such as between the computer motherboard and the LCD screen, between the mobile phone motherboard and the flip LCD screen, etc.), the core wires at the edge will be larger than those at the edge. The core wire in the middle is subject to high tension. When this kind of cable is used, especially for the connection of active circuit board components, the core wire with high tension at the edge is easy to break and affects the reliability of electronic communication equipment.

Embodiment 1

[0037] Such as Figure 1 to Figure 3 As shown, a flat cable with a connector is composed of a flat cable 1 and a connector 2 located at both ends of the flat cable; wherein the flat cable 1 is composed of a plurality of flat core wires that are glued together; on the connector A single row of pins 3 is provided; the flat cable 1 includes two parts of an un-teared cable 11 and a torn cable 12; the length of each core wire in the un-teared cable 11 is the same; the torn cable The length of each core wire in 12 is different, and the tear length y of each core wire in the torn cable 12 satisfies the following formula:

[0038] y = ( D - d d ) 2 X x 2 + ( L - m 2 ) 2

[0039] among them, | x | ≤ d 2 ;

[0040] In the formula: x is the distance between a core wire in the unteared cable 11 and the center line of the unteared cable 11; D is the width of the connector 2; d is the width of the unteared cable ...

Embodiment 2

[0056] Such as Figure 4 As shown, a cutting die for a flat cable with a connector includes a die body and a knife edge; wherein the knife edge is arc-shaped, and the arc curve equation is:

[0057] y = ( D - d d ) 2 X x 2 + ( L - m 2 ) 2

[0058] In the formula: D is the width of the connector; d is the width of the unteared cable in the flat cable; L is the total length of the core wire in the middle of the flat cable; m is the length of the core wire of the unteared cable.

[0059] Specific example: suppose the length (L) of the flat cable with connector is 100mm, the unteared length (m) is 60mm, the width (d) of the flat cable is 20mm, and the width (D) of the connector is 40mm, then the core wire The tear length y from the tear to the end is

[0060] y = ( 40 - 20 20 ) 2 X x 2 + ( 100 - 60 2 ) 2

[0061] inferred: y = x 2 + 400

[0062] That is, ...

Abstract

The invention discloses a flat cable with connectors and a cutting die of the flat cable with the connectors and relates to the field of flat cables. The problem that in an existing flat cable with connectors, core wires located on the edges are more tensioned than core wires located in the middle, in this way, fracturing is prone to occur, and then reliability of electronic communication equipment is affected is solved. The flat cable with the connectors comprises a flat cable body and the connectors located at the two ends of the flat cable body. Single-row contact pins are arranged on the connectors. The cutting die comprises a die body and a tool edge, wherein the tool edge is in an arc shape. According to the flat cable with the connectors, due to the formulated design, the length of core wires of a torn cable body meets the changes, relative to the flat cable body, of the width of the connectors; in this way, stress is even, the service life of the flat cable is prolonged, and the reliable using requirement for the flat cable in the electronic communication equipment is met; the cutting die can be adopted for manufacturing the flat cable with the connectors in batches, operation is convenient, accuracy is high, and the flat cable is stressed evenly.

Description

Technical field [0001] The invention relates to the field of flat cables, in particular to a flat cable with a connector and a cutting mold thereof. Background technique [0002] In an existing flat cable with a connector, the width of the connector is generally greater than that of the flat cable. When the flat cable core wire is connected to the connector, the core wire at both ends of the flat cable must be In this way, if the core wire of the flat cable is the same length and connected with the connector (such as between the computer motherboard and the LCD screen, between the mobile phone motherboard and the flip LCD screen, etc.), the core wire at the edge will be more The core wire in the middle is subjected to high tension. When this kind of cable is used, especially when connecting movable circuit board components, the core wire with high tension at the edge is easily broken and affects the reliability of electronic communication equipment. . Summary of the invention ...
