Description

TECHNICAL FIELD

[0001] The utility model discloses a connector, especially a connector female socket, a connector and a circuit board assembly, belongs to electronic component and application technical field. BACKGROUND

[0002] Connectors, also known as electrical connectors, are components used to facilitate the transmission of power or signals between electrical devices. Electrical connectors establish electrical connections between devices through metal contacts (pins or plugs), typically used to connect wires, cables, or circuit boards, and their primary function is to ensure that electrical current or signals can be reliably and efficiently transmitted from one device to another.

[0003] Currently, common connectors are widely used in various fields such as display devices, industrial equipment, automobiles, consumer electronics, and communication equipment.

[0004] In the design of large LED display screens, the female connector structure plays a crucial role. As the electrical interface of the display screen, the connector is responsible for transmitting power signals, control signals, and other signals to LED modules or panels. Therefore, the design of the female connector structure must have reliability, durability, and good electrical performance.

[0005] In the current market, LED display screens are usually powered by 220V AC mains power. In existing technology, the commonly used 220V "pin" connector is basically installed and fixed by welding the conducting pins on the PCB. When the male plug is inserted into the female socket, the female socket is prone to lifting, which poses a certain safety hazard. The conducting pins in the connector are mostly rectangular in structure, and there is no shielding structure between the conducting pins. In addition, the structure design of the connector insertion opening is relatively large, and during use, the user's hand may accidentally touch the conducting pins, causing safety accidents. On the other hand, the rectangular conducting pin structure has a relatively large size, and the tail of the conducting pin cannot be bent. In order to weld the conducting pin to the PCB, additional parts are needed to handle the corner, which increases the cost of raw materials and labor costs. Due to the structure limitation, the copper needle at the tail of the female connector socket cannot be safely protected by the plastic shell, and there is a safety hazard during use. SUMMARY

DETAILED DESCRIPTION

[0083] Please refer to the accompanying drawings Figure 1 to the accompanying drawings Figure 9 The utility model mainly protects a female socket of an electric connector, mainly including a female housing 11 and a female conductive needle 110, the female housing 11 is made of plastic material, the female conductive needle 110 is provided with more than one, more than one female conductive needle 110 is respectively embedded in the female housing 11, the female housing 11 bottom is provided with pin foot 13, when using, pin foot 13 can be clamped on the circuit board, the utility model can be assisted and fixed through pin foot 13.

[0084] In the embodiment, the female head shell 11 is internally formed with a plug cavity 16 for accommodating the male plug when the two are plugged together. The opening of the plug cavity 16 is arranged on the front end surface of the female head shell 11. One or more female head conductive needle sleeves 15 are fixedly arranged inside the plug cavity 16. Each female head conductive needle sleeve 15 is internally inserted with a female head conductive needle 110. The female head conductive needle sleeve 15 is integrally injection molded with the female head shell 11. Due to the insulation of the female head conductive needle sleeve 15, the female head conductive needles 110 inside the plug cavity 16 will not cause an arc phenomenon (i.e., the process of causing an electric arc through power, gas or other means, also known as electric arc discharge, which exists in some electric power equipment, lamps, display screens and other fields). Therefore, the spacing between adjacent female head conductive needles 110 can be very small, thereby minimizing the overall structure of the product. In the embodiment, the female head conductive needle sleeve 15 is shaped in a special shape to match the internal shape of the plug cavity 16. In the embodiment, the female head conductive needle sleeve 15 is arranged in a "pin" shape inside the plug cavity 16. A strip-shaped groove 118 is arranged between adjacent female head conductive needle sleeves 15 to divide the female head conductive needle sleeves 15 into independent individuals. Due to the special design of the female head conductive needle sleeve 15 and the "pin" shape arrangement, the female head conductive needle sleeve 15 has a foolproof function to prevent reverse plugging. The "pin" shape arrangement structure can make the conductive needle clamping tighter, limit the shaking of the plug through the shell, and does not need a special anti-loose structure, thereby making the structure simpler, easier to process, smaller in size, and suitable for narrow space environments.

In the embodiment, the diameter of the part of the pin feet 13 inserted into the pin holes 19 is larger than the diameter of the part of the pin feet 13 inserted into the circuit board. In specific implementation, the diameters of the two parts can be designed to be the same, or the diameter of the part of the pin feet 13 inserted into the pin holes 19 can be smaller than the diameter of the part of the pin feet 13 inserted into the circuit board. In the embodiment, the pin feet 13 can be made of hardware materials. When the pin feet 13 are inserted into the circuit board, they can be welded by soldering to make them more secure. In specific implementation, threads can be arranged on the pin feet 13. When the pin feet 13 are inserted into the circuit board, they can be fixed by nuts. In the embodiment, the pin feet 13 are in a cylindrical structure. Whether the pin feet 13 are processed or the pin holes in the circuit board are processed, the process is simple and convenient. In specific implementation, the pin feet 13 can be designed in a square column, a triangular column, a strip column, a special-shaped column or other structures.

In the embodiment, more than one female head insulating piece 14 is arranged inside the protective cover 12, which is used for isolating the rear end of the female head conductive needle 110, so that arc phenomenon does not occur between the rear ends of the female head conductive needle 110. Preferably, the female head insulating piece 14 is arranged in parallel with the left and right side plates of the protective cover 12.

[0087] In the embodiment, the top surface of the protective cover 12 can be provided with a pin identification, so that the function of each female head conductive needle 110 can be easily known through the pin identification, so that the connection is not wrong during wiring.

[0091] In the embodiment, the female head plug-in end 112 is internally provided with a crown spring accommodating cavity 117, and the crown spring 111 is inserted into the crown spring accommodating cavity 117. The crown spring 111 is a separate component independent of the female head conductive needle 110, and the crown spring 111 is in the shape of a waist drum, that is, the middle position is relatively thin, and the two end positions are relatively thick.

The tails of the conductive pins are also arranged in a "pin" shape, increasing the safety of use. At the same time, the grounding conductive pin is designed larger than the power supply conductive pin, enabling faster charge discharge in case of electric leakage and making the use safer.

[0104] Both the male plug and the female socket in the utility model are changed from the conventional large-opening structure to a small-opening structure, which can effectively prevent electric shock. The conductive pins are arranged in a "pin" shape, with a built-in anti-fooling function to prevent reverse insertion. Moreover, the "pin" shape arrangement structure can make the conductive pins be clamped more tightly. The晃动 of the plug can be restricted through the outer shell, eliminating the need for a special anti-loosening structure. The structure is simpler, the processing is convenient, the size is small, and it is suitable for environments with narrow spaces.
