Description

[Detailed description of the invention]

The present invention divides a plurality of wires into multiple groups, and press-fits each branch connector to the front end of each group of wires having different lengths.
This invention relates to a branch connector press-connecting device # of a type in which wires IIV- are aligned at the rear end and press-connected to one convergence connector. When connecting electronic circuits using a plurality of wires that are pressure-connected to connectors, each 1M child circuit is connected to one focusing connector by the distance ff1 position [-t! Even if one end of the plurality of wires is pressure-welded, the other end may have to be divided into several wires and have to be pressure-welded with a plurality of branch connectors to wire groups of different lengths to branch the wiring into multiple groups. many. When press-welding conventional connectors, the converging connector is press-welded using a press-welding machine, and then the single-branch connector extension is made by setting each wire in which should be press-fitted to each branch connector to a predetermined length by hand. The process of cutting the wires once the connectors are connected has been repeated once for each group of wires. Therefore, press-welding the branch connectors was an extremely time-consuming task. The present invention was developed in view of the above-mentioned circumstances, and includes a focusing connector at one end.

[-7 and connect multiple branch connectors to the other end,
It is an object of the present invention to provide a branch connector press-connecting device that can automatically press-connect wires with high efficiency even if the lengths of the wire groups to which each branch connector is press-connected are different. The present invention press-fits a converging connector to one end of a plurality of wires, and divides the wires into groups of various lengths at the other end of the wires, and press-fits a branch connector for each group, The branch connector is configured to include a connector pressure welding means, a transfer means, a latching means, a wire pulling means, a cutting means, and a focusing means as described below. and focusing connectors for our own 7 purposes (
(It is possible to perform pressure welding efficiently.) The connector pressure welding means includes a convergence connector press-contact part that press-contacts a plurality of wires to one convergence connector, and a convergence connector press-contact part that press-contacts a plurality of wires to one convergence connector, and a convergence connector press-contact part that press-contacts a plurality of wires to one convergence connector. It is equipped with a branch connector pressure welding part that press-fits the branch connector with the parts aligned.Both the connector pressure welding parts themselves (d) are known and are fed to the shape of the connector, and the front end of the wire is (The feeding direction of the wire is referred to as the front, and the front end is referred to as the front end.) The converging connector pressure contact part is located on the side, and the branch connector pressure contact part is located at the rear end 1FJ11, and the operation 1ICI order is , from the point of view of a group of wires, after the branch connector crimp section operates at the front end of the wire, the focusing connector crimp section is set to operate at the rear end of the wire group. a branch connector press-connecting section adjacent to the front of the branch connector press-connecting section, cutting the wire between both connector press-connecting sections, and simultaneously operating one connector press-connecting section;
The converging connector at the rear end of one wire cluster and the branch connector at the front end of the next wire cluster are simultaneously pressed together. The sleeping means simultaneously moves each branch connector press-welded to the front end of each wire group to a position at least forward of the wire length of the longest wire group (hereinafter referred to as the longest position).1. The branch connector is pushed from the rear and sent forward. Alternatively, it is conceivable to have a part that engages with the LD branch connector, and pull out 1 and 2 from the front and move it forward.
Any device that allows each branch connector to be moved to the longest position at the same time, ie, with the same amount of advancement, may be used. The latching means is adapted to latching the branch connectors at the set position 1u to prevent the branch connectors from retreating when each branch connector is retracted from the longest position fft by the wire pulling means described later. The above-mentioned set position refers to a position where each branch connector is advanced by the length of the wire group to be pressed from the first pressure-welding position of the converging connector that is pressed to the rear end of the wire. From the above point of view, the locking means is movable forward and backward so as to lock the branch connectors at any position, and is provided with locking elements at least as many as the branch connectors. The latching means may be configured such that the latching means emerges in the set position immediately before the wire is pulled back to be latched to the branch connector. If the front end of the casing pushes out the branch connector and moves it forward, and if the height of the casing is higher than the branch connector, the latching means always presses the top surface of the casing from above with constant pressure at the set position. However, when the casing moves backward, the latching means may be detached from the casing and directly latching the branch connector.However, in such a case, the latching means may be attached to the top surface of the casing so as to come into sliding contact with the top surface of the casing when the casing moves forward. It may be necessary to provide a rounded or sloped surface at the front end of the casing to prevent the branch connector from running over each set position. J drive for pulling back 2 (although there is no limitation at the time of d1', for example, it may be by rotating each reel winding the wire in the opposite direction). The cutting hand l-Z is disposed between the bundle connector pressure welding part and the branch connector pressure contact it+<, and extends so as to cut each of the above-mentioned wires (!)1z after the pull-back means is actuated. The width adjusting means is configured to move each wire, which is arranged at a pitch suitable for pressure welding of each branch connector, into the cutting ridge by one m.
This is a device that adjusts the width to match the pitch of the pins of the bundle connector, and consists of a function to align each wire in the same plane in parallel, and a part equipped with a machine 11 to stop the wires at equal pitches. Ru. For example, guide 9 that matches the pin pitch of each branch connector.
Arrange pieces having a product number of pieces on a common axis in a slidable state at each branch connector position, connect the piece at the end position to a driving part such as a cylinder, and bring each piece together by driving the cylinder, It is possible to arrange the width of the wires in the guide grooves of each piece to match the pitch of the pins of the focusing connector. Another solution is to simply guide the wire between a pair of parallel plates and push the wire closer to each other from the 1!11 direction. This is only effective if the wire thickness matches the pin pitch of the focusing connector. As described above, the crystal means constituting the present invention is such that the connector press-welding means press-fits each branch connector at a position where the IIF ends of each wire group are aligned 2, and then the transfer means presses the branch connector to the longest position. each latching element of the latching means is then set to a set position with the wire pressed into its respective branch connector, and then the wire is retracted by the wire retraction means to set each branch connector to the said setting. Then, the wires of each wire group are cut by the cutting means, and then the cut wires are brought to the pitch of the focusing connector by the cutting means, and then the wires are stopped at the corresponding hanging +)- elements. A focusing connector is pressed onto the rear end by the connector pressing means 1/c, thereby completing a series of connector pressing steps. Next, the embodiment shown in the drawings will be described.
