Description

Technical Field

[0001] The present application relates to the technical field of cable production, and in particular to a crimping device for crimping a header connector in the middle of a cable. Background Art

[0002] The cable is a connecting line composed of multiple wires connected side by side. Multiple wires transmit electrical signals synchronously, thereby realizing high-speed data transmission between two electronic devices. A bull-horn connector that can be connected to the electronic device is crimped on the cable. The bull-horn connector includes a main body and a cover body. The main body has multiple contacts arranged in sequence. The number of contacts is equal to the number of wires of the cable. Each contact is composed of a pair of thorns. A slot is formed in the middle of the pair of thorns, and the top of the thorn is a cutting edge. When crimping the bull-horn connector, the cable is placed between the main body and the cover body. Each pair of thorns corresponds to a wire. The cover body is pressed down by the crimping device so that the cutting edge of the thorn quickly pierces the sheath of the corresponding wire, and the core wire in the sheath is pressed into the slot to achieve contact and conduction between the core wire and the contact. At the same time, the cover body and the main body are combined into one to form a complete bull-horn connector. In order to ensure the quality and transmission efficiency of the cable, each wire should be pressed into a corresponding contact slot.

[0003] A commonly used crimping device at present includes a fixed jaw, a movable jaw and a rotating arm. During crimping, the bull-horn connector is first pre-fixed on the cable, and then placed between the fixed jaw and the movable jaw. The movable jaw is driven by the hand-cranked rotating arm to move, and the fixed jaw and the movable jaw squeeze the bull-horn connector and the cable, so that the bull-horn connector is crimped on the cable. However, due to the large number of wires in the cable, it is difficult to control the one-to-one correspondence between the wires and the contacts. When the operator places the cable and the bull-horn connector and during the crimping process, there is a slight angle deviation, which cannot ensure the correct positioning and docking of the cable and the bull-horn connector. After the crimping is completed, some contacts may not be pressed into the wire, and some contacts may be pressed into multiple wires, which will cause a circuit break or short circuit. The products produced can only be scrapped, which affects production efficiency and increases production costs. In addition, the crimping area of ​​the fixed jaw and the movable jaw of the existing crimping device is large. When crimping the bull-horn connector in the middle of the cable, it is easy to squeeze the bull-horn connector at the end of the cable, which is not convenient for crimping the bull-horn connector in the middle of the cable. Therefore, a new type of crimping device is urgently needed to solve the above problems.

[0020] Figure 1is a schematic structural diagram of the crimping device in the embodiment of the present application, such as Figure 1 As shown, and refer to Figure 2 The embodiment of the utility model provides a crimping device 100 for crimping a horn connector in the middle of a flat cable, comprising a base 110, a bracket 120 and a pressing block 130. The base 110 is a step structure to form a vertical stop surface 111 and a horizontal guide surface 112 connecting the lower end of the vertical stop surface 111. A limiting groove 113 perpendicular to the vertical stop surface 111 is also provided on the top of the base 110, and the limiting groove 113 passes through the top of the base 110. The bracket 120 is arranged on the base 110. The pressing block 130 is movably arranged on the bracket 120 in the vertical direction. The pressing block 130 is extended along the length direction of the limiting groove 113 and is located directly above the limiting groove 113.

[0021] In the crimping device 100 of the embodiment of the utility model, the process of crimping the horn connector on the cable is as follows: first, pre-fix the horn connector on the cable, install the horn connector into the limit groove 113, and place the cables on both sides horizontally on the horizontal guide surface 112 of the base 110. Then, move the cable toward the vertical stop surface 111, and drive the horn connector to move synchronously in the limit groove 113 until the cable contacts the vertical stop surface 111, and the horn connector is now directly below the pressing block 130. Finally, move the pressing block 130 downward, and the pressing block 130 squeezes the horn connector and the cable, and under the joint action of the limit groove 113, the horn connector is crimped on the cable.

[0022] In the present embodiment, since the flat cable is arranged in parallel under the action of the horizontal guide surface 112, and the bull-horn connector is arranged vertically with the flat cable under the action of the limiting groove 113, the flat cable and the bull-horn connector are kept in a vertical state during the movement and crimping process, so that the multiple wires of the flat cable and the multiple contacts of the bull-horn connector are plugged in one by one, avoiding the situation of breaking or short circuit of the flat cable, so that the crimping quality of the flat cable is better, the scrap rate is reduced, the production efficiency is improved, and the production cost is reduced.

[0023] Furthermore, the crimping device 100 can realize the crimping of the bullnose connector in the middle of the cable through the cooperation of the pressing block 130 and the limiting groove 113. During the crimping process, the cable on both sides and the bullnose connectors at the end are not affected, making the crimping process simpler and more convenient.

[0024] In some embodiments of the present application, Figure 1 and Figure 2As shown, the crimping device 100 further includes a guide block 140, which is disposed on the top of the base 110. A guide track 141 is provided on the guide block 140, and the guide track 141 passes through the guide block 140 in the vertical direction, and the guide track 141 has an opening facing one side of the horizontal guide surface 112. The guide track 141 is located directly above the guide groove and is connected to the guide groove. One end of the pressing block 130 is inserted into the guide track 141.

[0025] Since the movement of the pressing block 130 may be skewed during its vertical movement, the horn connector is subjected to uneven force when the pressing block 130 squeezes the horn connector, thereby affecting the crimping quality of the cable. In this embodiment, a guide track 141 is provided so that the pressing block 130 can only move in the guide track 141 and the guide groove in the vertical direction, thereby avoiding the movement of the pressing block 130 from being skewed and ensuring the crimping quality of the cable. In addition, the guide track 141 has a simple structure, is easy to design and manufacture, and has a low cost.

[0026] In some embodiments of the present application, Figure 1 As shown, the crimping device 100 further includes a lifting mechanism 150, which is disposed on the bracket 120 and has a lifting portion 151 that is movable in the vertical direction. The pressing block 130 is connected to the lower end of the lifting portion 151. In this embodiment, the lifting portion 151 of the lifting mechanism 150 can drive the pressing block 130 to move, so that labor can be saved, the labor intensity of the operator can be reduced, and the work efficiency can be improved.

[0027] In some embodiments of the present application, the lifting mechanism 150 is a cylinder. The cylinder is mainly composed of a cylinder barrel, an end cover, a piston, a piston rod and a seal. The cylinder is a cylindrical metal device that guides the piston to perform linear reciprocating motion in the cylinder barrel. The lifting part 151 of the lifting mechanism 150 is the piston rod of the cylinder. The cylinder has the advantages of simple structure, easy installation and maintenance, rapid action and fast response.

[0028] In this embodiment, the crimping process uses pneumatic power, which reduces the time of manually shaking the rotating arm in the existing crimping device 100, reduces labor intensity, and greatly improves work efficiency. In addition, the up and down stroke and pressure of the piston rod of the cylinder can be set to a suitable range, so that after the cable crimping is completed, the horn connector and the cable are not damaged, and the reliability of the crimping can be ensured. Furthermore, the device does not rely on the experience of the operator, and by setting appropriate parameters of the cylinder, the consistency and reliability of the crimping are guaranteed.

[0029] In some embodiments of the present application, the lifting mechanism 150 is a linear motor. A linear motor is a device that directly converts electrical energy into linear motion using the principle of electromagnetic action. The linear motor includes a motor cylinder, a telescopic rod and a magnetic circuit, and the telescopic rod can move telescopically in the motor cylinder. The lifting part 151 of the lifting mechanism 150 is the telescopic rod of the linear motor. The linear motor has the advantages of simple structure, high acceleration, easy adjustment and control, etc. The effect of the above-mentioned cylinder can also be achieved by setting the parameters of the linear motor, which will not be repeated.

[0030] In some embodiments of the present application, the crimping device 100 further includes a foot switch, which is electrically connected to the lifting mechanism 150 to control the lifting and lowering of the lifting portion 151 of the lifting mechanism 150 .

[0031] In this embodiment, the cylinder is used as an example. When the cable and the horn connector move to the vertical stop surface 111, the foot switch is stepped on to drive the piston rod of the cylinder to move downward, and the pressing block 130 is pressed downward, so that the horn connector is pressed on the cable, and then the foot switch is released, the piston rod rises, driving the pressing block 130 to rise. In this embodiment, by setting the foot switch, the movement of the cylinder can be controlled by the foot, making the control simpler and more convenient.

[0032] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the bracket 120 includes a vertical beam 121, a horizontal beam 122, a mounting plate 123 and a reinforcing block 124. The vertical beam 121 is arranged at one end of the base 110 away from the horizontal guide surface 112. The horizontal beam 122 extends along the length direction of the guide groove, and the horizontal beam 122 is located above the base 110, and one end of the horizontal beam 122 is connected to the upper end of the vertical beam 121. The mounting plate 123 is horizontally arranged at one end of the bottom of the horizontal beam 122 away from the vertical beam 121. The lifting mechanism 150 is installed on the mounting plate 123. The reinforcing block 124 is arranged at the connection between the vertical beam 121 and the horizontal beam 122.

[0033] In this embodiment, the reinforcement block 124 makes the connection between the vertical beam 121 and the horizontal beam 122 more secure, preventing the bracket 120 from shaking during the movement of the lifting mechanism 150. The installation plate 123 is provided to facilitate the installation and removal of the lifting mechanism 150. For example, the lifting mechanism 150 can be installed on the installation plate 123 by bolts. In addition, the bracket 120 in this embodiment has a simple structure, is easy to design and manufacture, and saves costs.

[0034] In some embodiments of the present application, the base 110 and the bracket 120 are both made of solid steel, so that the base 110 and the bracket 120 have high strength and heavy weight, thereby ensuring the stability of the crimping device 100 .

[0035] In some embodiments of the present application, the base 110 or the bracket 120 is a solid steel member.

[0036] In some embodiments of the present application, the complete working process of crimping the header connector to the middle of the flat cable is as follows:

[0037] 1. Pre-fix the main body and cover of the header connector to the designated position in the middle of the cable;
