Abstract

A plug-in type electrical connector includes: an insulating body, a first terminal group, a second terminal group, a grounding plate, an upper base member, a lower base member, a reinforcing fixing member, and a shielding shell. The first terminal group has a plurality of first conductive terminals, each of which has a first fixing section and a first welding section.

The spacing between the first fixing sections is enlarged, which can reduce the problems of short circuit, false welding, and empty welding when welding the terminals to the circuit board.

Description

Technical Field

[0001] The invention relates to an electrical connector, in particular to a straight-insertion plug electrical connector, which can increase the spacing between welding sections of conductive terminals to improve the welding success rate, and has a strengthening fixing element to improve the structural strength of the electrical connector being vertically fixed on a circuit board. Background Art

[0002] Electrical connectors are common electronic components on electronic devices. They can be connected to matching electrical connectors on other electronic devices to transmit signals and power between the two electronic devices. The existing Universal Serial Bus Type C electrical connector has an insulating body, two sets of conductive terminals, a circuit board, and a metal shell. The two sets of conductive terminals are arranged on the insulating body for signal transmission, and each conductive terminal has a welding section. The circuit board is arranged at the rear end of the insulating body, and a set of welding parts are respectively provided on the upper surface and the lower surface of the circuit board to weld with the welding sections of the two sets of conductive terminals. The metal shell covers the insulating body and the conductive terminals.

[0003] However, each group of conductive terminals is closely arranged, so that the spacing between adjacent welding sections is extremely small. When welding the welding sections to the welding parts of the circuit board, it is easy for the adjacent welding sections to be connected and short-circuited due to excessive solder, or to cause false soldering or empty soldering due to insufficient solder. This greatly increases the difficulty of the welding operation and reduces the productivity of the electrical connector.

[0004] In addition, when the electrical connector is vertically inserted and fixed on the circuit board, there is a lack of a high-strength fixing mechanism between the two. When the two are perpendicular to each other, the electrical connector is easily subjected to external force, causing the electrical connector to accidentally loosen or fall off. Summary of the invention

[0005] In view of the fact that the conductive terminals of the existing electrical connectors are prone to failure when being welded to the circuit board, and the electrical connectors lack a good fixing mechanism when being vertically fixed on the circuit board, the present invention improves the shortcomings and defects and further invents a straight-insertion plug electrical connector.

[0062] The first terminal group and the second terminal group are substantially point symmetrical with each other with the center point of the insertion space 100 as the symmetry center. The so-called point symmetry means that after the two terminal groups are rotated 180 degrees based on the symmetry center as the rotation center, the two terminal groups after rotation can completely overlap with the two terminal groups before rotation. Through the point symmetrical terminal group configuration, the high-speed plug connector can be smoothly inserted into the corresponding socket electrical connector when rotated 180 degrees and perform high-speed signal transmission operations normally.

In addition, the number of second conductive terminals 40 of the second terminal group can be two less than the number of first conductive terminals 20, wherein the distance between any two adjacent second welding sections 43 is greater than the distance between any two adjacent second fixed sections 41. In addition, the second welding section 43 of each second conductive terminal includes a second oblique extension section 431 and a second parallel section 432, wherein the second oblique extension section 431 extends obliquely outward from the rear end of the second fixed section 41, and the second parallel section 432 extends backward from the rear end of the second oblique extension section 431 and is parallel to the second fixed section 41, and the distance between any two adjacent second parallel sections 432 is greater than the distance between any two adjacent second fixed sections 41.

[0065] The grounding plate 35 is disposed between the first terminal group and the second terminal group and has a plurality of through holes 351 formed therethrough.

[0066] The two elastic buckle arms 30 are respectively formed on both sides of the grounding plate 35, fixed to the insulating body 10 and extending into the plug-in space 100, and the two elastic buckle arms 30 can be respectively arranged in the positioning groove 11. A grounding soldering foot 33 is respectively extended backward from the rear end of each elastic buckle arm 30 to be soldered on the circuit board 90 and provide a grounding function.

[0067] The base is disposed at the rear end of the insulating body 10 and inserted into the insertion space 100 , and the base includes an upper base component 60 and a lower base component 70 .

[0068] The upper base member 60 is disposed at the rear end of the insulating body 10 and above the grounding plate 35, and has an upper plug block 61, which is disposed in the plugging space 100. An upper fixing wing 62 is extended laterally outward on both sides of the upper plug block 61, and a combination hole 621 is formed through each upper fixing wing 62 for a bolt, a rivet or other fixing member to pass through and be installed on the circuit board 90. An upper fitting groove 615 is formed on the upper plug block 61 of the upper base member 60. A plurality of upper fixing columns 611 and a plurality of upper fixing holes 612 are formed on the upper base member 60, and the plurality of upper fixing columns 611 protrude downward and respectively pass through a portion of the through holes 351 of the grounding plate 35.

[0069] The lower base member 70 is disposed at the rear end of the insulating body 10 and below the grounding plate 35, and has a lower plug block 71, which is disposed in the plugging space 100 and is combined with the upper plug block 61.

A set hole 51 is formed through the reinforcing fixing member 50 to be inserted into the upper plug block 61 and the lower plug block 71. Two through holes 52 are formed through the reinforcing fixing member 50 to be aligned with the two coupling holes 621 of the upper base member 60 respectively. The through holes 52 are also used for bolts, rivets and other fixing parts to pass through to lock the straight plug electrical connector on the circuit board 90. The reinforcing fixing member 50 strengthens the structural strength of the upper base member 60.

[0071] The shielding shell is formed with a receiving space 800 to accommodate the insulating body 10, the first terminal set and the second terminal set. The shielding shell is formed with two engaging pieces 81 at the rear end to be respectively engaged in the upper engaging groove 615 and the lower engaging groove 715.
