[0001] The present application belongs to the technical field of FPC and connector assembly, and in particular to a jig for installing connector plug-in terminals, and a jig assembly thereof. Background Art

[0002] The existing connector comb and its comb teeth are integrally processed and formed, and the stress of the comb teeth is relatively concentrated and easy to break. If one of the comb teeth breaks, the entire comb will be scrapped and cause losses; the comb handle is small, which is not conducive to operation.

[0003] In the prior art, this structure is usually used in textile machinery and equipment, such as a solder heald needle fixing plate disclosed in the public document with publication number CN211939420U, which includes a fixing plate and a plurality of heald needles. The fixing plate is provided with a plurality of slots, and the slots are evenly spaced along the length direction of the fixing plate. Each slot is adapted to the heald needle, and each slot is fixedly connected to the corresponding heald needle by soldering, and the fixing plate is fixedly connected to the heald lifting rod on the loom.

[0004] Although a reinforcing rod and a bolt are provided to realize the detachable connection of the whole row of comb teeth, which is convenient for disassembly, if one of the comb teeth fixed by solder breaks, the whole row of comb teeth will be scrapped. Even the field span is relatively large, and ordinary technicians in this application cannot think of applying the improved structure in the comparative document to this application without a certain amount of creative labor.

[0005] Moreover, in the technical field of FPC and connector assembly, many technicians have designed some large-scale assembly machines to realize FPC and connector assembly. These machines are costly and have to constantly replace various types of fixed connector heads and fixed FPC structures, and the structures are extremely complex. Utility Model Content

[0006] The utility model aims to provide a jig in which the comb teeth are independently arranged and one comb tooth can be replaced individually after being damaged, in order to solve the problem that one of the existing comb teeth in a row is scrapped due to damage.

[0007] In order to achieve the above-mentioned technical objectives, the following first technical solution is provided: a jig for installing connector plug-in terminals, comprising a fixed plate and a plurality of comb teeth, the comb teeth being independent of each other, and a single comb tooth being embedded in the fixed plate and penetrating therethrough, one end of which extends out of the fixed plate and is clamped, and the other end is located in the fixed plate and is a free end; the fixed plate is fixedly connected to a support seat, and the support seat limits the free end of the comb tooth.

[0008] In an operative manner, the fixing plate has a channel for accommodating the comb teeth; the channel includes a fixing portion and a limiting portion; the comb teeth have a needle portion, and the end of the needle portion has a thick portion; the fixing portion fits with the needle portion, and the limiting portion fits with the thick portion.

[0009] In an practicable manner, the fixing plate and the supporting seat are fixedly connected by screws.

[0010] In order to solve the problem that the upper and lower rows of terminals usually need to be assembled simultaneously in the connector, the existing comb needs to repeatedly cross-push each row of terminals slightly, and the two rows of terminals cannot be pushed synchronously, and the steps are relatively cumbersome.

[0011] In order to solve the above-mentioned technical problems, the following second technical solution is provided: a jig assembly for installing a connector plug-in terminal, comprising two halves of a jig of the first technical solution, a cable arrangement channel parallel to the comb teeth being provided between the two halves of the jig, the comb teeth being located at the front end of the cable arrangement channel, and having two rows of comb teeth being located at the upper and lower sides of the cable arrangement channel; and the two halves of the jig are magnetically connected via a plurality of magnetic blocks, and the magnetic blocks are located on the left and right sides of the cable arrangement channel.

[0012] In an practicable manner, a connector fixing plate is also included, which is located at the front end of the two-piece fixture and is used to fix the connector.

[0013] In an implementable manner, the connector fixing plate has a card slot, and the card slot is opposite to the comb teeth.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The comb teeth and the comb handle of the fixture are separated, and the replaceability of a single comb tooth is achieved, reducing the scrap loss of the entire comb due to the breakage of a single comb tooth; and the comb handle is enlarged, making hand operation more comfortable and making production operations easier; the present application integrates the comb into a double-row component, which can synchronously and quickly advance the upper and lower rows of terminals, thereby improving assembly efficiency.

[0026] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0027] like Figure 1 and Figure 2 The first embodiment shown is a jig for installing a connector plug terminal, comprising a fixing plate 1 and a plurality of comb teeth 2, the comb teeth 2 being independent of each other, and a single comb tooth 2 being embedded in the fixing plate 1 and penetrating therethrough, one end of which protrudes from the fixing plate 1 and is engaged, and the other end is located in the fixing plate 1 and is a free end; the fixing plate 1 is fixedly connected to a support seat 4, and the support seat 4 limits the free end of the comb teeth 2. The fixing plate 1 and the support seat 4 are preferably fixedly connected by screws.

[0028] Specifically, the fixing plate 1 has a channel 3 for accommodating the comb teeth 2; the channel 3 includes a fixing portion 31 and a limiting portion 32; the comb teeth 2 have a needle portion 21, and the end of the needle portion 21 has a thick portion 22; the fixing portion 31 fits with the needle portion 21, and the limiting portion 32 fits with the thick portion 22.

[0029] The method for replacing a single damaged comb tooth 2 is to separate the fixing plate 1 and the support seat 4 by adjusting the screw. After separation, the free end of the comb tooth 2 is no longer limited by the support seat 4. The needle portion 21 of the damaged comb tooth 2 is moved by a tool or by hand, so that the free end of the damaged comb tooth 2 is exposed from the fixing plate 1, and then the needle portion 21 of the damaged comb tooth 2 can be continued to be acted on, or the free end of the damaged comb tooth 2 can be acted on to completely separate the damaged comb tooth 2 from the fixing plate 1. Select a good comb tooth 2, align the needle portion 21 with the channel 3 and extend it, and then press the free end of the comb tooth 2 until the free end is immersed in the fixing plate 1, and then fix the fixing plate 1 to the support seat 4 by bolts.

[0030] The comb teeth 2 are made of high-strength, high-toughness, low-deformation materials such as spring steel. The support seat 4 is made of low-density and high-strength materials such as aluminum alloy to reduce the weight of the entire component, increase the comb handle, and make the hand operation more comfortable. The fixing plate 1 is made of stainless steel to prevent product contamination. The screws are made of stainless steel.

[0031] like Figures 3 to 9 The second embodiment shown is a jig assembly for installing a connector plug-in terminal, which has two lobes of the jig in the first embodiment, and a cable channel 5 parallel to the comb teeth 2 is provided between the two lobes of the jig, the comb teeth 2 are located at the front end of the cable channel 5, and there are two rows of comb teeth 2 located at the upper and lower sides of the cable channel 5, and the cable channel 5 is used to place the cable. The two lobes of the jig are magnetically connected by a plurality of magnetic blocks 6, and the magnetic blocks 6 are located on the left and right sides of the cable channel 5; and when the magnetic blocks 6 interact with each other, no cable passes through.

[0032] The fixture assembly further comprises a connector fixing plate 7, which is located at the front end of the two-piece fixture and is used to fix the connector. The connector fixing plate 7 has a card slot 8, and the card slot 8 is opposite to the comb teeth 2.

[0033] Among them, in order to form a wiring channel 5, the single-chip embodiment 1 fixture located above also needs to open a notch at the lower part of the fixed plate 1, and similarly, a key slot is opened at the lower part of the support seat 4. Four slots are arranged on the left and right ends of the support seat 4, and circular magnetic blocks 6 are arranged in the slots. The single-chip embodiment 1 fixture located below is symmetrically arranged with the single-chip embodiment 1 fixture above in the horizontal plane. And the magnetic force of the magnetic block 6 is selected so that the upper and lower rows of comb handles can fit naturally and can be easily separated. The connector fixing plate 7 at the front end is made of low-density and high-strength materials such as aluminum alloy to reduce the weight of the entire assembly.

[0034] The working method of the fixture assembly is to first pre-assemble the cable terminal into the connector, then align and insert the lower single-petal fixture, and then align and insert the upper single-petal fixture, and after the two petals of the fixture are naturally magnetically attracted, fix the connector in the slot 8 of the connector fixing plate 7, and apply relative pressure to the connector fixing plate 7 and the upper and lower support seats 4 to make the cable terminal snap into place on the connector, and the two are firmly connected.

[0035] The above will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model.
