Description

Technical Field

[0001] The utility model belongs to the technical field of power connectors, and in particular relates to a positive electrode rod power connector. Background Art

[0002] DC power connectors are widely used in various electronic devices, such as televisions, computers, and large outdoor display devices. In these devices, external DC power supplies provide stable power support for the devices. Due to the different power consumption, voltage, and four-axis force requirements of different devices, power connectors of different specifications need to be designed. At present, similar DC power connectors are usually composed of a positive rod, a negative spring, a static terminal, a positive welding piece, a plastic body, and a plastic back cover. The positive rod is located in the center of the jack, and the negative spring is located on one side and connected to the static terminal. When the plug is inserted, the outer wall of the plug connects to the negative spring and squeezes and pushes the static terminal away, separating the negative spring and the static terminal, and the center of the plug contacts the positive rod to conduct to the riveted positive welding piece to form a power-on circuit.

[0003] However, there are the following problems during use:

[0004] 1. Sparks will be generated when the plug is inserted. This spark is an arc phenomenon when the power is turned on and connected to the load. It has certain safety hazards and affects the life of the plug and the DC power connector.

[0005] 2. The DC power socket without a protective shell has low four-way force, which may cause damage to electronic equipment due to excessive force when plugging and unplugging the plug;

[0006] 3. The positive electrode rod and the positive electrode welding piece are connected by riveting. Loose riveting will cause poor contact and temperature rise and intermittent power supply, which has certain safety risks and potential damage to electronic equipment. Utility Model Content

With such a design, the cooperation of the limiting groove and the limiting buckle can achieve the purpose of foolproofing the shell and the main body, ensure the accuracy of the installation angle, and the cooperation of the locking protrusion and the locking groove can realize the anti-slip fixed installation of the shell.

[0017] It is further defined that the negative terminal includes a first pin, a first connecting arm, a first current guide arm, a first docking arm and a first grounding cantilever. Such a design matches and positions the slot to ensure contact strength.
