Description

socket connector

The utility model relates to a socket connector, in particular to a socket connector which is telecommunications-connected with a circuit board and can provide butt joint with a plug connector.

At present, as the speed of computer transmission of signals becomes faster and faster, the number of conductive terminals of computer connectors used for telecommunication transmission is also increasing, making the arrangement of conductive terminals in the insulating body of the connector more and more dense. Therefore, accommodating a large number of terminals in a space-limited insulating body becomes a technical challenge. Furthermore, the single-slot design of existing connectors is the current basic form. In the case of limited plane space on general circuit boards, single-slot electrical connectors are the mainstream. For related designs, please refer to Taiwan Patent Application No. 84112993, Cases 85103740, 85203116 and 86206353. However, in view of the requirements of high-speed transmission, although the existing single-slot receptacle connector can meet the demand by increasing the density of the conductive terminal arrangement, the density of the conductive terminal arrangement is very limited after all, and the printed circuit board configuration In the case of limited location, it is obviously not feasible to extend the longitudinal dimension of the connector to meet the demand. Therefore, how to meet the requirements of high-speed transmission in the limited plane space of the circuit board, the breakthrough of the connector form is obviously very important.

The purpose of the utility model is to provide a connector with high-speed transmission effect by increasing the docking groove to provide more conductive terminals, and can be properly configured on the printed circuit board.

The purpose of the utility model is achieved by the following technical solutions: the insulating body of the connector is a square body, and at least two sides of the square body are equipped with docking slots, which can provide at least two telecommunications insertion spaces. According to the above main features, wherein at least two docking slots on the insulating body are arranged oppositely, the adjacent sides of the two docking slots of the insulating body can also be provided with docking slots to provide more telecommunications plugging space. The adjacent sides of the two docking slots of the insulating body are provided with guide columns, which can be docked and guided with the docking connector.

Compared with the prior art, the utility model has the advantages of providing more signal plugging space and making the connector have high transmission characteristics.

Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.

Please refer to FIG. 1 and FIG. 2 , the utility model socket connector 1 is composed of an insulating body 2 , a shielding body 3 and a conductive terminal 4 . Wherein the insulating body 2 is a square body, and a pair of opposite edges of the square insulating body 2 are respectively provided with a butt joint groove 10, the butt joint groove 10 does not penetrate the insulating body 2, so it is not shown in Fig. 1, please refer to Fig. 2 Since two butt slots 10 are provided on the insulator body 2 of the present invention, its width is slightly larger than that of the existing single butt slot connector. However, when the number of conductive terminals increases, the increase in length is only The length of the receptacle connector of a docking slot is increased by half, so its overall dimension increases uniformly around, which is convenient for being arranged on a printed circuit board with limited planar space. In addition, a pair of guiding grooves 11 for combining with a plug connector (not shown) are provided along another pair of opposite edges of the square insulating body 2 . When the two guide grooves 11 are set to be different in size or shape, they not only have a guiding function, but also can prevent the receptacle connector from being reversed when mated with the plug connector, and have the effect of identifying the orientation during insertion. Conductive terminals 4 are closely arranged on both sides of the docking groove 10 (only a few conductive terminals are drawn in the figure for illustration), and its contact end 42 is used to electrically connect with the contact portion (not shown) of the mated plug connector, and The welding end 41 can be welded with the printed circuit board after proper bending. The two sides of the shielding body 3 are provided with two docking groove through holes 17 corresponding to the docking groove 10, so that the contact portion (not shown) of the corresponding plug connector is inserted into the contact end of the conductive terminal 4 in the docking groove 10. 42 is turned on. In addition, two guide groove through holes 18 are provided on both sides of the shielding body 3 corresponding to the position of the guide groove 11, so that the guide groove 11 and the corresponding guide post ( not shown) to match. A piece is dug out between the two butt joint grooves 10 on the insulating body 2 to form a square through hole 12, and at the same time, a through hole 19 is also provided at the corresponding through hole 12 in the middle of the shielding body 3, and the space provided by the through hole 12 is utilized. Other electronic components may be provided to make best use of the limited area of a printed circuit board (not shown). Furthermore, the electrical guide strips 5 that are cut and bent directly from the opposite sides of the shielding body 3 can realize a grounding loop with the printed circuit board (not shown) through the corresponding slots 6 provided on the insulating body 2, Make the electrical guidance have the "best and shortest path" to produce the best grounding and shielding effect. In addition, the shielding body 3 is further provided with a riveting foot 7 on the opposite side edge, which is used to cooperate with the corresponding riveting groove 8 on the insulating body 2, so that the insulating body 2 and the shielding body 3 can be riveted and fixed. The four corners of the bottom surface of the insulating body 2 are provided with guiding rods 9 for guiding and positioning, which can guide the receptacle connector 1 to a printed circuit board (not shown). Please refer to FIG. 3 , which is a three-dimensional assembly diagram of the socket connector 1 of the present invention, which can show the specific form of the socket connector 1 after assembly. Please refer to Fig. 4 and Fig. 5. The combination of the conductive terminals 4 of the socket connector 1 of the present invention is a unified combination of adjacent inner rows of terminals and distant outer rows of terminals, as shown in Fig. 4 and Fig. 5 As shown, the inner and outer rows of conductive terminals 4 are first formed on the material tape 20. When assembling the conductive terminals 4, the conductive terminals 4 are assembled from the bottom side of the insulating body 2 (refer to FIG. 1), and are pressed together with the material tape 20 to the butt joint.
