Description

Technical Field

[0001] The utility model relates to the field of electronics, in particular to the technical field of high-density long-pin electric connectors, and in particular to a high-density long-pin electric connector installation limiting tool. Background Art

[0002] High-density long-pin electrical connectors are inter-board connectors used to interconnect printed circuit boards. Since high-density long-pin electrical connectors have a large number of pins and small gaps between pins, and high installation and positioning requirements, the crimping and welding of high-density long-pin electrical connectors has always been a major problem in electronic assembly. This type of electrical connector with densely packed pins and too long beyond the surface of the printed circuit board is highly dependent on the operating skills of personnel during assembly. If there is a slight deviation in the alignment process, the matching electrical connectors will not be able to align and engage, and the electrical interconnection between the printed circuit boards cannot be achieved. Therefore, it is not an easy project to ensure that these pins are "standing straight" and "standing firm" on the printed circuit board.

[0003] The pin surface of the high-density long-pin electrical connector uses a plating process, generally gold-plated. The gold-plated layer on the pin surface cannot be damaged, otherwise it will affect the electrical conductivity and signal continuity of the electrical connector.

[0004] After reviewing the installation of the currently used high-density long-pin electrical connectors, there are two situations: the first type of crimping electrical connector does not have its own limiting gasket, and the root of the pin will be affected by stress during installation and crimping, and the pin surface will inevitably be scratched by the tool; the second type of welding electrical connector has its own limiting gasket for pin installation, but in order to meet the electronic assembly requirements of electrical connectors on high-reliability products, the limiting gasket will affect the soldering tin penetration rate, so the gasket will still be removed during welding and cannot play a limiting role. Currently, there are no installation tools for high-density long-pin electrical connectors on the market, nor are there suitable installation solutions to solve the problem of pin limiting. It can only rely on experienced operators to manually proofread the operation. Utility Model Content

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0024] As Figure 1 shown, a high-density long-pin electrical connector mounting limit tooling 1 is provided, which is composed of a comb-shaped limit insertion plate 102 and a quick-release handle 101, and the two are connected by a flower-shaped locking screw 103.

[0025] 1) Comb-shaped limit insertion plate 102:

[0026] According to the pin layout matrix of the high-density long-pin electrical connector 4, a special comb-shaped limiting insertion plate 102 is designed to match it. To prevent damage to the gold-plated layer on the surface of the pins of the high-density long-pin electrical connector 4 and at the same time play a limiting role during the installation process, the comb-shaped limiting insertion plate 102 needs to have a certain strength, and the material used for the insertion plate is polyimide. Positioning is carried out according to the cylinders at both ends of the high-density long-pin electrical connector 4. The slots of the insertion plate are semi-circular and open, and the peripheries of the slots are rounded to facilitate insertion along the pins. When all the pins smoothly penetrate into the coupling holes of the printed circuit board 2, the comb-shaped limiting insertion plate 102 can be withdrawn from the pins of the high-density long-pin electrical connector 4, which is convenient for clamping and improves production efficiency.

[0027] 2) Quick-release handle 101:

[0028] In the electronics industry, due to the variety of models of the high-density long-pin electrical connector 4, there will also be a variety of comb-shaped limiting insertion plates 102. To facilitate the operator's use, the quick-release handle 101 is designed as a general component, and quick disassembly and assembly are achieved through the petal-shaped locking screws 103.

[0029] Working principle

[0030] As Figures 2-4 shown, during the actual operation process, according to the model of the high-density long-pin electrical connector 4, the corresponding comb-shaped limiting insertion plate 102 is selected. The comb-shaped limiting insertion plate 102 is inserted into the through slot of the quick-release handle 101 and fastened with 2 petal-shaped locking screws 103.

[0031] One comb-shaped limiting insertion plate 102 is inserted along the root from the front of the pins of the high-density long-pin electrical connector 4, and another comb-shaped limiting insertion plate 102 is inserted from the rear of the pins of the high-density long-pin electrical connector 4 close to the inserted insertion plate. The two comb-shaped limiting insertion plates 102 form a diamond-shaped limiting grid among the pins. As Figure 4 shown, at this time, the pins do not deviate at all in the small diamond-shaped limiting grid. The two are attached and slowly move upward vertically. When moving to about 5 mm away from the pin heads, it is fixed. Under the action of the comb-shaped limiting insertion plate 102, the pins of the entire high-density long-pin electrical connector 4 can smoothly penetrate into the corresponding coupling holes of the printed circuit board 2 or the backing plate 3, etc. all at once within a few seconds, and electronic assembly of the high-density long-pin electrical connector 4 is achieved through crimping or soldering.

[0032] Meet the product design requirements that the coupling gap between the high-density long-pin electrical connector 4 and the printed circuit board 2 is less than 0.2 mm. After the electronic assembly process (crimping or soldering) is completed, the pins are straight and not bent. The pins of the high-density long-pin electrical connector 4 can be integrally inserted into the coupling holes of the printed circuit board 2 all at once, and they are in one-to-one correspondence without deviation, realizing the electrical interconnection between the printed circuit boards 2.

[0033] A tight fit is achieved between the printed circuit board 2 and the high-density long-pin electrical connector 4, greatly reducing the damage to the gold plating layer that may be caused by the through-holes of the printed circuit board 2 and the penetration connection of the pins. It preferably solves the reliability, safety and operability required for the crimping or soldering of the high-density long-pin electrical connector 4.

[0034] The problem that the self-limiting gasket of the high-density long-pin electrical connector 4 hinders the flow of solder is solved, enabling the solder to smoothly flow to the through-holes of the printed circuit board 2 and form effective wetting on the welding termination surface, avoiding airtight welding and meeting the technical requirement of 100% solder penetration rate for the solder joints of the through-hole devices.

[0035] Previously, the manual alignment working hours of the high-density long-pin electrical connector 4 were about 1 hour per piece. After using the installation limiting tooling 1 for the high-density long-pin electrical connector 4, it only takes about 10 seconds per piece, greatly saving the production working hour cost.

[0036] As described above, it is only the preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present invention by using the methods and technical contents disclosed above, or modify it into an equivalent embodiment with equivalent changes without departing from the scope of the technical solution of the present invention. Therefore, all equivalent changes made according to the shape, structure and principle of the present invention without departing from the content of the technical solution of the present invention shall be covered by the protection scope of the present invention.
