Technical Field

[0001] The utility model belongs to the technical field of SMC connectors, and in particular relates to a female connector for SMC 90-degree docking. Background Art

[0002] PCB boards used in industry are generally equipped with many connectors, and traditional connectors generally use 2.54PITCH specification connectors.

[0003] The ends of the contact pieces in a group of terminals on a traditional female connector are bent or folded outward to form an opening, which is convenient for the terminal contact part of the male connector to be inserted into. However, such a setting is prone to loosening after long-term plugging and unplugging, resulting in the male and female connectors being loose after docking, thus affecting their normal use.

[0006] A main body shell, wherein one side of the main body shell is evenly provided with docking ports up and down, and the other side is evenly provided with mounting holes up and down, and the docking ports are connected with the mounting holes;

[0007] The terminal is installed in the main shell, and the terminal is installed in the main shell by extending into the installation hole. The terminal includes an upper terminal and a lower terminal. The upper terminal and the lower terminal both include a fixing part and a contact part. The end of the contact part is an upper and a lower spring sheet, and the spring sheet is a torsion spring sheet.

[0008] As a preferred embodiment of the above technical solution, the upper terminals and lower terminals are arranged alternately up and down, and the corresponding torsion springs on the upper terminals and lower terminals are arranged on the opposite side of the upper terminals and lower terminals, so that the upper and lower torsion springs are arranged side by side up and down.

[0009] As a preferred embodiment of the above technical solution, the corresponding fixing portion on the upper terminal faces upward, and the corresponding fixing portion on the lower terminal faces downward, a welding foot is fixed on the other side of the fixing portion, and the welding foot is kept perpendicular to the fixing portion.

[0010] The beneficial effects of the utility model are:

[0011] 1. The utility model sets a torsion spring on the contact part of the terminal, which will produce a certain pressure, and provide a certain damping and friction force after twisting, so that the contact part on the male connector can be inserted between the two torsion springs to produce close contact, and the docking is more stable. Moreover, when the connector is subjected to vibration or impact, it can also effectively prevent the contact part on the male connector and the two torsion springs from loosening or falling off;

[0012] 2. The SMT of the utility model is fixed on the surface of the PCB board by horizontal welding, and the female connector also adopts this fixing method, so that the male and female connectors are in a horizontal docking state when connected, which effectively improves the space required for the connector, reduces the size of the connector, and is conducive to the miniaturization of the terminal equipment.

[0020] Example

[0021] like Figure 1-4 As shown;

[0022] The SMC 90-degree docking female connector includes a main housing 1, one side of the main housing 1 is evenly provided with docking ports 2, which match the contact portion on the male connector, and the other side is evenly provided with mounting holes 6, which are connected with the mounting holes 6. The contact portion on the male connector can be inserted into the mounting holes 6 through the docking ports 2, so that the contact portion on the male connector can be inserted into the corresponding contact portion 34 on the terminal 3; the terminal 3 is installed in the main housing 1, and the terminal 3 is installed in the main housing 1 by extending into the mounting holes 6. The terminal 3 includes an upper The terminal 31 and the lower terminal 32, the upper terminal 31 and the lower terminal 32 all include a fixing portion 33 and a contact portion 34, the end of the contact portion 34 is an upper and lower spring sheet, the spring sheet is a torsion spring sheet 35, the torsion spring sheet 35 will produce a certain pressure, and at the same time provide a certain damping and friction force after twisting, so that the contact portion on the male connector can be inserted between the two torsion spring sheets 35 to produce a close contact, the docking is more stable, and when the connector is subjected to vibration or impact, it can also effectively prevent the contact portion on the male connector and the two torsion spring sheets 35 from loosening or falling off;

[0023] Furthermore, the upper terminal 31 and the lower terminal 32 are arranged alternately up and down, and the corresponding torsion springs 35 on the upper terminal 31 and the lower terminal 32 are arranged on the opposite side of the upper terminal 31 and the lower terminal 32, so that the upper and lower torsion springs 35 are arranged side by side up and down, so that the contact part on the upper male connector can be normally matched, which is highly practical;

[0024] Furthermore, the terminal 3 is fixed on the surface of the PCB board by SMT horizontal welding, and the male connector also adopts this fixing method, so that the male and female connectors are in a horizontal docking state when connected, which effectively improves the space required for the connector, is conducive to the miniaturization of the terminal equipment, and keeps 1.27PITCH between adjacent terminals, further reducing the size of the connector, which is conducive to the wiring of the terminal product PCB board; and there is no need to pre-select and break the PCB board, saving production costs;
