Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and specifically to a side-standing electrical connector. Background Technology

[0002] Electrical connectors are primarily used for signal transmission between electronic devices. USB interfaces, as a standard input / output interface, are widely used in various electronic devices. Most existing USB connectors have a flat, horizontal structure with a horizontally designed connector. The soldering leads used to connect to the relevant circuit board extend from the rear of the metal casing and bend downwards. The plane of the soldering leads is perpendicular to the plane of the connector. When assembled on a circuit board, this type of USB connector occupies a large space, which is detrimental to circuit board miniaturization. It also hinders the distribution design of other electronic components and makes it difficult to adapt to the electronics industry's trend towards lighter, thinner, shorter, and smaller devices.

[0003] Side-mounted electrical connectors effectively solve the aforementioned problems associated with flat, horizontal USB connectors. For example, Chinese patent CN207572569U discloses a side-mounted electrical connector comprising a shielding shell, an insulating body, and contact terminals. The shielding shell contains an upper insulating body, a lower insulating body, an upper row of contact terminals, and a lower row of contact terminals. The upper insulating body is fixedly connected to the upper row of contact terminals, and the lower insulating body is fixedly connected to the lower row of contact terminals. Several pins are provided on the side of the shielding shell for fixed connection to the PCB board. This side-mounted electrical connector reduces the space occupied by the product on the PCB, ensures product structural stability, improves productivity, and reduces production costs. However, the existing side-mounted electrical connectors still have the following defects: (1) The pins of the terminals of the existing side-mounted electrical connectors are arranged in two rows of parallel side-by-side (not staggered), which makes it easy for the terminals to generate crosstalk during signal transmission and is difficult to meet the application requirements of high-frequency scenarios; (2) There is no suction top plate, which makes it inconvenient for the side-mounted electrical connectors to move during the actual assembly and production process, as well as to be plugged in and unplugged during use; (3) The terminal pins and the plastic core are fitted with a slot, which is easy to leave gaps, weakening the fixing and waterproofing capabilities between the terminals and the plastic core. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a side-mounted electrical connector. Through the structural design of the plastic body, metal shell, and terminal block assembly, crosstalk generated by the terminals during signal transmission can be reduced, meeting the application requirements of high-frequency scenarios. Furthermore, the terminal block assembly and the plastic body adopt an integral injection molding connection method, which improves the fixation and waterproofing capabilities between the terminal block assembly and the plastic body.

[0005] To achieve the above technical solution, this utility model provides a side-mounted electrical connector, comprising: a plastic body, a metal shell, and a terminal block assembly. The terminal block assembly is integrally injection-molded and fixed within the plastic body, and the plastic body is embedded within the metal shell. The plastic body includes a plastic core, with a suction top plate integrally formed on its top. The left and right sides of the middle portion of the plastic core are provided with shell mating center limiting grooves. A tongue plate is integrally formed at the front end of the plastic core, and the tongue plate is provided with a PIN mounting groove. Limiting protrusions are provided at the top and bottom of the front end of the tongue plate. The metal shell includes a shell core, and the left and right sides of the shell core are provided with shell mating center limiting grooves formed on the plastic core. The plastic body is inserted into the outer shell body after the fixing buckle is aligned with the groove. The connection between the plastic body and the metal shell is achieved through the cooperation between the fixing buckle bent inward and the limiting groove in the middle of the outer shell. The terminal block group consists of seven terminal pins. Each terminal pin includes a pin contact head. The pin contact head is integrally injection molded and installed in the pin mounting groove provided on the plastic body. The end of the pin contact head is integrally provided with two downwardly bent and staggered pin branches. The pin branches are fixed in the plastic body by integral injection molding and extend beyond the bottom plane of the plastic body. The bottom of the plastic body is provided with a downwardly protruding PCB board positioning post.

[0006] Preferably, the plastic body has bottom limiting grooves on both the left and right sides of its bottom. After the plastic body is inserted into the outer shell body, the bottom side of the outer shell body is embedded in the bottom limiting grooves. This can further improve the stability of the assembly between the plastic body and the metal shell.

[0007] Preferably, the tongue plate is provided with a mating limiting groove behind the limiting protrusion, and the left and right sides of the rear end of the tongue plate are provided with insertion and removal buffer slopes to provide better protection for the tongue plate during actual insertion and removal.

[0008] Preferably, the terminal block assembly consists of seven terminal pins arranged side-by-side at intervals. The top of the PIN contact head of the uppermost terminal pin has an upwardly protruding PIN pin upper contact spring, which is located within a limiting protrusion at the top of the front end of the tongue plate. The bottom of the PIN contact head of the lowermost terminal pin has a downwardly protruding PIN pin lower contact spring, which is located within a limiting protrusion at the bottom of the front end of the tongue plate. In actual assembly, the PIN pin upper and lower contact springs located within the limiting protrusion at the front end of the tongue plate form contact with external signals and protect the terminal pins.

[0009] Preferably, the PIN contact head of the terminal PIN pin arranged at the top is provided with an upper PIN pin fixing piece, and the PIN contact head of the terminal PIN pin arranged at the bottom is provided with a lower PIN pin fixing piece, so as to improve the stability of the terminal PIN pin fixing.

[0010] Preferably, the pin pins of the terminal pins arranged at the top are provided with pin pin protrusions.

[0011] Preferably, the bottom of the outer shell body is integrally provided with a downwardly extending outer shell welding foot, the front side of the outer shell welding foot is provided with a reinforcing rib, and the left and right sides of the outer shell welding foot are provided with welding notches. By providing reinforcing ribs, the outer shell welding foot can be ensured not to deform in actual production. By providing welding notches, it is easier and more secure to weld to the PCB board in the subsequent process.

[0012] Preferably, the front end of the housing body has an arc-shaped chamfer at the insertion port, and the front and rear sides of the housing body have inwardly protruding bulges. By providing an arc-shaped chamfer at the front end of the housing body, the protection of the front end of the insertion port can be enhanced, making the insertion and removal of the side-mounted vertical electrical connector smoother.

[0013] Preferably, the top plate of the suction plate is provided with a top plate limiting groove on both the left and right sides, which makes it more convenient to insert and remove the vertical electrical connector on this side.

[0014] The advantages of this side-standing electrical connector are as follows: It features a simple and reasonable structure, easy assembly, and compact size. The integrated suction plate on top of the plastic body greatly facilitates the movement of the plastic body during actual production and assembly, and also facilitates insertion and removal during use. The terminal block assembly and the plastic body are connected by an integrated injection molding method, greatly improving the fixation and waterproofing capabilities between them. The plastic body and the metal shell are connected by a fixing buckle, which facilitates rapid assembly and improves the stability of the assembled components. The pins at the bottom of the terminal block assembly are designed with a double-row staggered distribution, reducing crosstalk during signal transmission and meeting the requirements of high-frequency applications. The downward-protruding PCB board positioning post at the bottom of the plastic body facilitates rapid positioning and connection between the side-standing electrical connector and the PCB board.
