Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to an improved socket connector. Background Technology

[0002] A socket connector, often simply called a socket, is an electronic component or assembly designed to provide an electrical connection interface, allowing the transmission of current or signals between or within devices. Socket connectors are widely used in various electronic devices, electrical systems, and communication networks, and are key components in building complex circuit systems and ensuring effective communication between devices. A socket connector provides contacts or pins that allow current or signals to pass through. These contacts typically mate with corresponding pins on a plug (also called a plug connector) to form a complete circuit connection. In communication equipment and networks, socket connectors are used to transmit analog or digital signals. These signals can be audio, video, data, or other types of information.

[0003] Current socket connectors mainly consist of an insulating body and multiple terminals. The insulating body has slots, and the terminals are located on the insulating body. The pins of the terminals are distributed within the slots, and the solder pads of the terminals extend beyond the insulating body. However, in existing technology, the slot opening faces directly forward or upward. Correspondingly, the plug connector is inserted into the slot horizontally or vertically to make contact with the pins and establish electrical connection. The plug connector cannot be inserted at an angle, and current socket connectors cannot be adapted for insertion when the interface is located at a corner of the chassis. Therefore, it is necessary to research a solution to these problems. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main objective is to provide an improved socket connector that can effectively solve the problem that existing socket connectors cannot accommodate the tilted insertion of plug connectors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An improved socket connector includes an insulating body, a plurality of lower row terminals, and a plurality of upper row terminals. The insulating body has a slot with an opening tilted towards the front and upward. The plurality of lower row terminals are arranged side by side at intervals on the insulating body. Each lower row terminal has a lower pin and a lower solder foot. The lower pins are arranged side by side in the slot and extend tilted towards the front and upward. The lower solder feet are arranged side by side behind the insulating body and extend horizontally. The plurality of upper row terminals are of a stamped blanking structure. The plurality of upper row terminals are arranged side by side at intervals on the insulating body. Each upper row terminal has an upper pin and an upper solder foot. The upper pins are arranged side by side in the slot and extend tilted towards the front and upward. The upper pins are tilted and parallel to the lower pins, respectively, and are directly opposite each other. The upper solder feet are arranged side by side behind the lower solder feet and extend horizontally. The upper solder feet are located behind the lower solder feet and on the same horizontal plane. The upper solder feet and the lower solder feet are staggered left and right.

[0007] As a preferred embodiment, both the lower and upper pins extend upwards out of the slot.

[0008] As a preferred embodiment, the rear end face of the insulating body is provided with a plurality of lower fixing holes, which are arranged side by side at intervals. Each lower fixing hole is connected to a slot, and each lower row of terminals has a lower fixing part. The lower fixing part is integrally connected between the lower insertion pin and the lower solder foot. The lower insertion pin passes through the corresponding lower fixing hole from back to front, and the lower fixing part is inserted into the corresponding lower fixing hole for fixation.

[0009] As a preferred embodiment, the rear end face of the insulating body is recessed with multiple limiting grooves, which are arranged side by side at intervals. Each limiting groove has an upper fixing hole on its bottom surface, and each upper fixing hole communicates with a slot. Each upper row of terminals has an upper fixing part and a limiting part. The upper pin, upper fixing part, limiting part and upper solder foot are integrally formed and connected in sequence. The upper pin passes through the corresponding upper fixing hole from back to front. The upper fixing part is inserted into the corresponding upper fixing hole for fixation. The limiting part is embedded in the corresponding limiting groove.

[0010] As a preferred embodiment, the upper welding foot and the limiting part are directly formed by blanking to create a curved structure, and the limiting part is bent and connected perpendicularly to the upper fixing part.

[0011] As a preferred embodiment, the upper terminal is formed by stamping a metal sheet with a thickness of 0.5mm, the upper solder foot has a thickness of 0.5mm, and the upper pin has a thickness of 0.4mm after being thinned.

[0012] As a preferred embodiment, both the lower and upper rows of terminals extend at a 30° angle.

[0013] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0014] By tilting the slot opening towards the front and upward, and with multiple lower and upper pins also tilted forward and upward, this product can accommodate tilted plug connectors, meeting the requirements for use where the interface is located at the corner of the chassis. At the same time, the multiple upper terminals have a stamped blanking structure, and the multiple upper solder feet are located behind the multiple lower solder feet and on the same horizontal plane, ensuring the coplanarity of each solder foot, which is beneficial to improving production efficiency and yield.

The bottom surface of each limiting groove 13 has an upper fixing hole 14, and each upper fixing hole 14 communicates with the slot 11. There are seven limiting grooves 13 and seven upper fixing holes 14, and the number is not limited. Furthermore, the limiting grooves 13 are L-shaped. Additionally, two fixing posts 15 extend downwards from the bottom of the insulating body 10, arranged on the left and right sides, for external mounting and fixing.

[0035] Multiple lower-row terminals 20 are arranged side-by-side and spaced apart on the insulating body 10. Each lower-row terminal 20 has a lower pin 21 and a lower solder foot 22. The lower pins 21 are arranged side-by-side in the slot 11 and extend obliquely forward and upward. The lower solder feet 22 are arranged side-by-side behind the insulating body 10 and extend horizontally. In this embodiment, the lower-row terminal 20 extends at a 30° angle, and the lower pin 21 extends upward beyond the slot 11. Each lower-row terminal 20 has a lower fixing part 23, which is integrally connected between the lower pin 21 and the lower solder foot 22. The lower pin 21 passes through the corresponding lower fixing hole 12 from back to front, and the lower fixing part 23 is inserted into the corresponding lower fixing hole 12 for fixation.

[0036] The plurality of upper terminals 30 are stamped and blanked structures. These upper terminals 30 are arranged side-by-side and spaced apart on the insulating body 10. Each upper terminal 30 has an upper pin 31 and an upper solder foot 32. The upper pins 31 are arranged side-by-side in the slot 11 and extend obliquely forward and upward. The upper pins 31 and lower pins 21 are respectively obliquely and parallel to each other vertically. The upper solder feet 32 ​​are arranged side-by-side behind the insulating body 10 and extend horizontally. The upper solder feet 32 ​​are located behind the lower solder feet 22 and on the same horizontal plane. Furthermore, the upper solder feet 32 ​​and lower solder feet 22 are staggered left and right. In this embodiment, the upper terminal 30 extends at a 30° angle, and the upper pins 31 extend upward beyond the slot 11. Each upper row of terminals 30 has an upper fixing part 33 and a limiting part 34.

The limiting part 34 is bent perpendicularly to the upper fixing part 33. In addition, the upper row of terminals 30 is formed by stamping a metal sheet with a thickness of 0.5mm. The upper solder foot 32 has a thickness of 0.5mm, and the upper pin 31 is thinned to a thickness of 0.4mm.

[0037] The manufacturing and assembly process of this embodiment is described in detail below:

[0038] First, the insulating body 10 is injection molded, and multiple lower row terminals 20 and multiple upper row terminals 30 are stamped.

In use, the product is fixed to an external circuit board, and the multiple lower solder pads 22 and multiple upper solder pads 32 are soldered onto the corresponding pads to achieve conductivity. Then, the corresponding plug connector is inserted into the slot 11. After insertion, the multiple lower pins 21 and multiple upper pins 31 make contact with the corresponding terminals inside the plug connector.

[0039] The key design feature of this invention is that by tilting the slot opening towards the front and upward, and with multiple lower pins and multiple upper pins also tilted towards the front and upward, this product can be adapted to the tilted insertion of plug connectors, meeting the requirements for use when the interface is located at the corner of the chassis. At the same time, the multiple upper terminals are made of a stamped blanking structure, and the multiple upper solder feet are located behind the multiple lower solder feet and on the same horizontal plane, ensuring the coplanarity of each solder foot, which is beneficial to improving production efficiency and yield.
