Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a novel female connector. Background Technology

[0002] A female header is a universal connector widely used in electronics, electrical appliances, and instruments. It mainly serves to transmit current or signals and is usually used in conjunction with a pin header to form a board-to-board connection. As an important cornerstone of internal electrical connections in electronic equipment, it has broad application prospects and significant technical value.

[0003] As electronic devices continue to evolve towards miniaturization, thinness, and high performance, higher demands are placed on the performance and installation of power strips. When existing power strips are installed on circuit boards, they tend to occupy too much vertical space, leading to an increase in the overall thickness of the electronic device. In some space-sensitive application scenarios, they are difficult to adapt to complex circuit board layouts and space requirements. Utility Model Content

[0004] Therefore, it is necessary to provide a new type of female connector.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A novel female connector, comprising:

[0006] An insulating body, wherein limiting portions are respectively provided at both ends of the insulating body, and multiple insertion channels are provided on the insulating body;

[0007] The device has multiple pins, each pin corresponding to a specific insertion channel. Each pin includes a plug-in portion, a connecting portion, an inclined portion, and a soldering portion. The first end of the plug-in portion is disposed inside the first end of the insertion channel. The connecting portion abuts against the outer surface of the limiting portion. The first end of the connecting portion is bent and connected to the second end of the plug-in portion. The inclined portion is inclined along the direction from the first end to the second end of the insertion channel.

[0025] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, a novel female connector 10 includes: an insulating body 100 and a plurality of pins 200. Limiting portions 110 are respectively provided at both ends of the insulating body 100. A plurality of insertion channels 120 are formed on the insulating body 100. Each pin 200 corresponds one-to-one with a insertion channel 120. Each pin 200 includes: a insertion portion 210, a connecting portion 220, an inclined portion 230, and a soldering portion 240. The first end of the insertion portion 210 is disposed within the first end of the insertion channel 120. The connecting portion 220 abuts against the outer surface of the limiting portion 110. The first end of the connecting portion 220 is bent and connected to the second end of the insertion portion 210. The inclined portion 230 is inclined along the direction from the first end to the second end of the insertion channel 120. The first end of the inclined portion 230 is connected to the second end of the connecting portion 220. The soldering portion 240 is connected to the second end of the inclined portion 230.

[0026] In this embodiment, each insertion channel 120 is configured as two sets spaced apart on the insulating body 100, and each pin 200 is correspondingly configured as two sets distributed at both ends of the insulating body 100. By providing limiting portions 110 at both ends of the insulating body 100, the insertion portion 210, connecting portion 220, inclined portion 230, and soldering portion 240 of the pin 200 are connected in sequence. That is, the insertion portion 210 of the pin 200 is located inside the first end of the insertion channel 120 on the insulating body 100, and the connecting portion 220 of the pin 200 is bent and abuts against the outer surface of the limiting portion 110. With the inclined portion 230 inclined along the direction from the first end to the second end of the insertion channel 120, a reverse-fitting soldering portion can be formed. The 240 structure allows for the formation of pins 200 with a reverse-mount shape on the insulating body 100. During mounting, the insulating body 100 can be mounted in reverse on the cutout area of ​​the circuit board via the limiting part 110, i.e., the limiting part 110 abuts against the outer edge of the cutout area of ​​the circuit board. The insulating body 100 passes through the cutout area of ​​the circuit board and is located on the other side of the circuit board. The reverse-mount pins 200 can be tightly bonded to the pads on the circuit board for soldering. This not only effectively reduces the vertical height and can adapt well to space-constrained application scenarios, but also facilitates the soldering of the pins 200 since the insulating body 100 is located on the other side of the circuit board, reducing soldering defects and ensuring a stable electrical connection.

[0027] In one embodiment, such as Figure 1 As shown, the limiting part 110 is provided with a plurality of limiting grooves 310, and the connection part 220 of each pin 200 is located in the limiting groove 310. Specifically, each limiting groove 310 is evenly distributed on the limiting part 110 of the insulating body 100, and the connection part 220 of each pin 200 is located in a limiting groove 310 respectively. This allows the pins 200 to be orderly and spaced apart on the insulating body 100, without interference between the pins 200. Furthermore, the soldering part 240 of the pin 200 can be accurately aligned with the solder pads on the circuit board, ensuring the electrical performance and signal integrity when the pins 200 are connected.

[0028] In one embodiment, such as Figure 1 As shown, the limiting portion 110 is provided with a plurality of limiting protrusions 320, which are arranged sequentially at intervals. A limiting groove 310 is formed between every two adjacent limiting protrusions 320. Specifically, by uniformly distributing a plurality of limiting protrusions 320 on the limiting portion 110, and by forming a limiting groove 310 between every two adjacent limiting protrusions 320 to accommodate the connection portion 220 of the pin 200, the pins 200 can be orderly and spaced apart on the insulating body 100 by setting the limiting protrusions 320.

[0029] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, a guide slope 111 is provided on the end of the limiting portion 110 away from the insulating body 100. Specifically, by providing the guide slope 111 on the limiting portion 110, the pin 200 can be bent from the first side of the limiting portion 110 to the second side of the limiting portion 110, that is, the inclined portion 230 can be better inclined along the direction from the first end to the second end of the insertion channel 120 to form a welding portion 240 structure for reverse bonding, thereby better forming a pin 200 structure with a reverse bonding shape on the insulating body 100.

[0030] In one embodiment, such as Figure 3 As shown, two elastic plug tabs 211 are spaced apart on the plug portion 210, and a plugging area 201 is formed between the two elastic plug tabs 211. Specifically, the two elastic plug tabs 211 are spaced apart on the plug portion 210 and located within the plugging channel 120. When the external pin header is plugged into the novel female connector 10, it is plugged into the plugging area 201 between the two elastic plug tabs 211, which can achieve a stable connection between the pin header and the female connector.

[0031] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the insulating body 100 has a mounting slope 130 on the side away from the limiting part 110. Specifically, by providing the mounting slope 130 on the insulating body 100, the width of the insulating body 100 on the side away from the limiting part 110 can be reduced, thereby allowing the insulating body 100 to be better inserted into the cutout area of ​​the circuit board, facilitating the mounting of the insulating body 100 on the circuit board.

[0032] In one embodiment, the width of the second end of the insertion channel 120 is greater than the width of the first end of the insertion channel 120. Specifically, by setting the width of the second end of the insertion channel 120 to be greater than the width of the first end of the insertion channel 120, it is easier for external pin headers to be inserted into the insertion channel 120, and they can be better inserted into the insertion area 201 between the two elastic insertion pieces 211.

[0033] In one embodiment, the insulating body 100 is made of a liquid crystal polymer. Specifically, liquid crystal polymer (LCP) has excellent high-temperature resistance, electrical insulation properties, and molding and processing properties. By using liquid crystal polymer as the material of the insulating body 100, the insulating body 100 can have excellent high-temperature resistance, electrical insulation properties, and molding and processing properties, which facilitates injection molding of the insulating body 100 and ensures the quality and reliability of the insulating body 100.

[0034] In one embodiment, the insulating body 100 and the limiting part 110 are integrally formed. Specifically, by making the insulating body 100 and the limiting part 110 an integral structure, and by making the insulating body 100 and the limiting part 110 an integral injection-molded structure, not only can the stability of the overall structure of the insulating body 100 and the limiting part 110 be enhanced, but also the insulating body 100 with the limiting part 110 is obtained integrally by injection molding, which facilitates production and processing.

[0035] In one embodiment, the plug-in portion 210, the connecting portion 220, the tilting portion 230, and the soldering portion 240 are integrally formed. Specifically, by making the plug-in portion 210, the connecting portion 220, the tilting portion 230, and the soldering portion 240 an integral structure, the overall structural stability of the pin 200 can be enhanced, giving the pin 200 better mechanical strength, thereby ensuring a stable electrical connection between the pin 200 and the circuit board.

[0036] Compared with the prior art, the present invention has at least the following advantages:

[0037] This utility model provides a novel female connector. By providing limiting portions at both ends of the insulating body, the insertion portion, connection portion, inclined portion, and soldering portion of the pins are sequentially connected. With the inclined portion inclined along the direction from the first end to the second end of the insertion channel, a reverse-fitting soldering portion structure can be formed. This allows the formation of a pin structure with a reverse-fitting shape on the insulating body. During mounting, the insulating body can be reverse-mounted onto the cutout area of ​​the circuit board through the limiting portions. The reverse-fitting pins can be tightly fitted to the solder pads on the circuit board for soldering. This not only effectively reduces the vertical height and can well adapt to space-constrained application scenarios, but also facilitates the soldering of the pins and ensures a stable electrical connection.
