Description

Technical Field

[0001] The utility model relates to the field of terminal assembly jigs, in particular to a clip cutting mechanism of a loose-pin quick assembly device. Background Art

[0002] If the spacing of the terminals on the material strip is different from the spacing of the plastic shell holes, then these terminals, namely loose pins, can only be manually installed into the plastic shell one by one. This production method reduces the overall assembly speed and increases production costs. Therefore, it is very necessary to design a connector loose pin quick assembly device that can be quickly assembled by an air gun. The principle is to use an air gun to drive the loose pins into the terminal holes of the plastic shell, and the design of how to cut the loose pins and load them into the "magazine" is particularly important. Utility Model Content

[0003] In view of the deficiencies in the prior art, the main purpose of the present invention is to provide a clip cutting mechanism for a loose-pin quick assembly device that can conveniently break the terminal strip and limit the position of each terminal.

[0004] The top of the cutting base is provided with a sunken groove, and a plurality of lower strip grooves are opened on the sunken groove, and the lower strip grooves are arranged in a one-to-one correspondence with the upper strip grooves. The upper strip grooves, the sunken grooves and the lower strip grooves form a first terminal channel for the terminals to pass through. The front and rear ends of the cutting clip are respectively provided with a front slot and a rear slot, and the front gear teeth and the rear gear teeth can be inserted into the front slot and the rear slot respectively, and the front gear teeth and the rear gear teeth are respectively provided with racks that extend into the upper strip groove and can block the terminals.

[0005] Preferably, the cutting clip and the cutting base are fixedly connected by screws.

[0006] Preferably, a socket is provided on the cutting base, and a docking groove corresponding to the socket is provided on the lower pre-breaking pressure plate.

[0007] Preferably, the top of the lower pre-breaking plate and the bottom of the upper knife plate are respectively provided with abutment portions capable of contacting the terminal strip.

[0008] Compared with the prior art, the present invention has the following advantages: the upper knife pressure plate is fixed to the cutting base by screws, the lower pre-breaking pressure plate and the rear gear are respectively inserted into the cutting base and the cutting clip, and then the terminal strip is inserted into the first terminal channel, the head of the terminal is blocked by the rack of the rear gear, and then the lower pre-breaking pressure plate is manually lifted, and the terminal strip is pushed all the way to the upper knife pressure plate. At this time, the terminal strip is fixed, and then the rear gear is removed, and the front gear is inserted into the front slot of the cutting clip, and then the terminal strip is manually broken, so that the terminals become scattered pins, and the scattered pins will slide along the first terminal channel to the rack of the front gear and be blocked.

[0009] Remove the front gear, and then use an air gun to blow the loose needles from the first terminal channel of the clip cutting mechanism into the terminal hole on the plastic shell. The structure of this solution has the function of a "clip", which can realize the cutting of terminal strips and the use of an air gun to blow the loose needles into the terminal hole of the plastic shell.

DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figure 1 As shown, a clip cutting mechanism 1 of a loose needle quick assembly device includes a cutting clip 11 and a cutting base 12. The rear end of the cutting base 12 is provided with a lower pre-breaking plate 14 that can fix the terminal strip 13 and an upper knife pressing plate 15 that is arranged above the lower pre-breaking plate 14 and can abut the terminal strip 13. The bottom of the cutting clip 11 is provided with a plurality of upper strip grooves 16, and the top of the cutting base 12 is provided with a sunken groove 17, and the sunken groove 17 is provided with a plurality of A lower strip groove 18 is arranged in a one-to-one correspondence with the upper strip groove 16. The upper strip groove 16, the sunken groove 17 and the lower strip groove 18 form a first terminal channel 19 for the terminal to pass through. The front end and the rear end of the cutting clip 11 are respectively provided with a front slot and a rear slot. The front slot and the rear slot can be inserted into the front gear teeth 20 and the rear gear teeth 21 respectively. The front gear teeth 20 and the rear gear teeth 21 are respectively provided with racks 22 that extend into the upper strip groove 16 and can block the terminal.

[0020] The present invention provides a clip cutting mechanism 1 of a quick assembly device for loose needles. When in use, the upper knife pressure plate 15 is fixed to the cutting base 12 by screws, and the lower pre-breaking pressure plate 14 and the rear gear 21 are respectively inserted into the cutting base 12 and the cutting clip 11. Then, the terminal strip 13 is inserted into the first terminal channel 19, and the head of the terminal is blocked by the rack 22 of the rear gear 21. Then, the lower pre-breaking pressure plate 14 is manually lifted, and the terminal strip 13 is pushed all the way to the upper knife pressure plate 15. At this time, the terminal strip 13 is fixed, and then the rear gear 21 is removed, and the front gear 20 is inserted into the front slot of the cutting clip 11. Then, the terminal strip 13 is manually broken, so that the terminals become loose needles, and the loose needles will slide along the first terminal channel 19 to the rack 22 of the front gear 20 and be blocked.

[0021] Remove the front gear 20, and then use an air gun to blow the loose needles from the first terminal channel 19 of the clip cutting mechanism 1 into the terminal hole on the plastic shell. The structure of this solution has the function of a "clip", which can realize cutting the terminal strip 13 and blowing the loose needles into the terminal hole of the plastic shell using an air gun.

[0022] Preferably, the cutting clip 11 is fixedly connected to the cutting base 12 by screws, so as to ensure the connection effect.

[0023] Preferably, a socket 23 is provided on the cutting base 12 , and a docking groove 24 corresponding to the socket 23 is provided on the lower pre-breaking pressure plate 14 .

[0024] The socket 23 cooperates with the docking slot 24 to enable manual lifting of the lower pre-breaking pressure plate 14 .

[0025] Preferably, the top of the lower pre-breaking plate 14 and the bottom of the upper knife plate 15 are respectively provided with abutment portions 25 capable of contacting the terminal strip 13 .

[0026] The diameter of the abutment portion 25 is smaller than the body diameter of the lower pre-breaking plate 14 and the upper knife plate 15, so that the contact area with the terminal strip 13 is small, the force is greater, and it is more convenient to break the terminal strip 13. Of course, the terminal strip 13 in this solution is pre-marked with a breaking line.

[0027] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention.
