Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more particularly to a bent through-hole connector. Background Technology

[0002] Connectors are components that electronic engineers frequently encounter. Their function is very simple: to bridge gaps in circuits or between isolated circuits, allowing current to flow and enabling the circuit to perform its intended function. Connectors are indispensable components in electronic devices; following the path of current flow, you will always find one or more connectors. Connector forms and structures are incredibly diverse, varying depending on the application, frequency, power, and operating environment.

[0003] Chinese patent CN210576875U discloses a 90° elbow connector, a plug assembly, and a socket assembly. The plug housing on the plug assembly and the socket housing on the socket assembly are fitted together and tightly coupled. After connection, the signal terminals are connected to the signal jack to realize signal transmission.

[0004] Although the terminals and spring contacts connect to conduct electricity and transmit signals, the stability of the connection is limited. This is because the preload between the terminals and spring contacts is limited, and the connection causes the terminals and spring contacts to make active contact, resulting in a relatively high contact resistance. As the temperature of the terminals and spring contacts rises, their mechanical properties will decrease to some extent, gradually leading to an increase in temperature. In other words, the temperature of various components in electronic and electrical equipment gradually increases above the ambient temperature, which in turn reduces the conductivity. This puts the entire elbow connector in a state of long-term thermal fatigue, resulting in a decrease in the performance of the elbow connector. Utility Model Content

The above structure achieves precise positioning, which is simple and convenient, and facilitates assembly and disassembly, greatly improving work efficiency.

[0022] 3. Placing the positioning block in the positioning slot allows for quick connection between the tail cap and the vertical end. This operation is simple and convenient, requiring no additional positioning or limiting structures, greatly saving costs and facilitating disassembly and installation, significantly improving work efficiency. Furthermore, the clamping end applies force to the pressing head, ensuring it remains pressed against the cable, thus clamping it securely and reliably, preventing the cable from falling out of the connector and maximizing safety.

[0023] 4. The shielding assembly prevents external electromagnetic fields from affecting the connector's signal transmission and also prevents internal signal energy from radiating outwards and interfering with other devices, effectively improving the connector's EMC (electromagnetic compatibility) capability. Simultaneously, the fins can be snapped onto the housing, inner core I, and inner core II, enabling rapid positioning without the need for welding or screws, simplifying the assembly process and greatly improving work efficiency.

[0035] like Figures 1 to 6As shown, this utility model discloses a bent through-hole connector, including a housing 1. The housing 1 has an integrally formed horizontal end 11 and a vertical end 12. In this preferred embodiment, the horizontal end 11 and the vertical end 12 are integrally injection molded, that is, the housing 1 is a plastic part. This structure can achieve lightweighting and significantly reduce costs.
