In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0033] like Figure 1 and Figure 2As shown in the figure, the utility model discloses a plug-in type crystal head module connector, including a plug-in board base 100, a printed circuit board 200, a plug module 300 and a socket module 400, and the plug-in board base 100 is provided with a product installation end and a module connection end on both sides. Among them, the printed circuit board 200 is connected to the product installation end of the plug-in board base 100, and the plug-in type crystal head module connector can be directly connected to the product. In order to meet the needs of new products that are becoming increasingly multifunctional and to further simplify the assembly process, a plug module 300 and a socket module 400 are plugged into the module connection end of the plug board base 100. The plug module 300 specifically includes a plurality of crystal plug assemblies 310. The design of the plug board type crystal head module connector in this way can aggregate the connection positions, reasonably plan and save space and manufacturing costs; accordingly, the socket module 400 is provided with a plurality of jacks 410, and the jacks 410 are arranged one by one with the crystal plug assemblies 310 to adapt to and improve the assembly requirements of the product; the plug terminals 3121 of the crystal plug assemblies 310 can pass through the plug board base 100 and the printed circuit board 200 in sequence, and similarly, the socket terminals 420 of the socket module 400 can also pass through the plug board base 100 and the printed circuit board 200 in sequence, so that the electrical signals of the plug board type crystal head module connector are unobstructed.

[0034] Specifically, the crystal plug assembly 310 includes a crystal housing 311, a positioning member, and a wire. The wire is loaded into the crystal housing 311 and then pressed into the positioning member, so that the crystal housing 311 is connected to the positioning member and the wire is clamped, and the installation of the crystal plug assembly 310 is completed. Exemplarily, the wire includes a plurality of single wires 312, and part of the single wires 312 protruding from the crystal housing 311 is set as a plug terminal 3121. The end of the crystal housing 311 close to the plug terminal 3121 is provided with a buckle portion 3111, and the buckle portion 3111 can pass through the plug board base 100 and be clamped with the printed circuit board 200, so as to adjust the structure of the plug terminal 3121 and the socket terminal 420 and the printed circuit board 200, and effectively save space.

[0035] In the present embodiment, the material of the crystal shell 311 is polybutylene terephthalate, referred to as PBT, which is a polyester made by the polycondensation of terephthalic acid and 1,4-butanediol and is an important thermoplastic polyester. The polybutylene terephthalate used in the production of the crystal shell 311 is generally a semi-crystalline thermoplastic polyester with high transparency, high heat resistance, and resistance to organic solvents. Moreover, polybutylene terephthalate is non-toxic and has no irritating effect on the skin and human body, and the production process does not have any adverse impact on the environment.

[0036] Furthermore, the crystal shell 311 is required to have a flammability UL94 rating of V-0. The flammability UL94 rating is the most widely used standard for the flammability performance of plastic materials. It is used to evaluate the ability of a material to extinguish after being ignited. Specifically, a rating of V-0 satisfies the requirement that after two 10-second combustion tests on the sample, the flame is extinguished within 30 seconds and no burning material can fall. Combined with the material of the crystal shell 311, polybutylene terephthalate, this flame retardant property is given, with the characteristics of high gloss, high toughness and good dimensional stability. Exemplarily, the material of the plugboard substrate 100 is also polybutylene terephthalate.

[0037] Specifically, the alignment piece is provided with a plurality of alignment grooves at intervals, and a plurality of single wires 312 are alternately abutted against the bottom and top of the alignment grooves, respectively, to form a double-row staggered arrangement structure. Exemplarily, the crystal plug assembly 310 is set as an RJ45 plug. It can be understood that the wire is an unshielded twisted pair, which is generally composed of 8 wires of different colors divided into 4 pairs twisted together. When introduced into the crystal plug assembly 310, it needs to be disassembled into 8 single wires 312 corresponding to 8 plug terminals 3121, and correctly arranged as required. The double-row staggered structure saves more space and is less prone to errors and confusion.

[0038] In this embodiment, three crystal plug assemblies 310 are arranged at intervals along the first direction, and the docking port of each crystal plug assembly 310 is perpendicular to the plug board base 100; the socket module 400 and the crystal plug assembly 310 are arranged at intervals along the second direction, and correspondingly, the jacks 410 are arranged at intervals along the first direction, and the docking port of the jacks 410 is parallel to the plug board base 100 and faces outward, which is convenient for plugging and use. In order to more conveniently assemble the plug board type crystal head module connector, the socket module 400 is provided with a positioning member 430, and the printed circuit board 200 is provided with a positioning hole 210. The positioning member 430 can pass through the plug board base 100 and be placed in the positioning hole 210, which is used to position the socket module 400 and set the jack 410 corresponding to the crystal plug assembly 310. Similarly, the socket module 400 is provided with a socket buckle 440 at one end close to the socket terminal 420, and the socket buckle 440 can also pass through the plug board base 100 and be clamped with the printed circuit board 200, further stabilizing the structure of the plug board type crystal head module connector.

[0039] Illustratively, the printed circuit board 200 is welded to the plug-in board base 100, which can more stabilize the structural installation of the plug-in crystal head module connector. FR-4 grade material is selected as the base material of the printed circuit board 200, specifically a composite material made of epoxy resin combined with glass fiber cloth as a reinforcing material, and the board material has a flame retardant grade of UL94V-0, has excellent electrical insulation performance, mechanical strength and high temperature resistance, and can still maintain its high mechanical value and electrical insulation even in dry or humid conditions, with high quality and low price.

[0040] In this embodiment, the substrate of the printed circuit board 200 is green, and the gold plating process is used to produce a metal plating layer on the surface of the printed circuit board 200 by chemical oxidation-reduction reaction. The advantage of the gold plating process is that the color of the deposited metal on the surface of the printed circuit board 200 is stable, the brightness is good, the plating is flat, the welding performance is good, and the service life is long. Further, the thickness of the metal layer of the gold plating process is limited to 1-3Uinch, which is about 0.025-0.075um. The color is more golden and brighter than the ordinary gold plating process, and more beautiful; and after the gold plating of the substrate of the printed circuit board 200, since only nickel gold is on the pad, the transmission of the signal in the skin effect is on the copper layer and will not affect the signal, and the solder mask on the circuit is more firmly combined with the copper layer; the crystal structure of gold plating is denser than that of gold plating, and it is not easy to oxidize.

[0041] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
