technical field

The utility model relates to a probe connector, in particular to a probe connector with better electrical connection effect.

Background technique

Probe connector is an electronic component mainly used in electronic products such as mobile phones. It is used to connect the metal contacts of detachable electronic components such as batteries or smart cards (SIM cards), so that the batteries or smart cards can be installed after installation. Enabled by electronic products.

Commonly used probe connectors usually include an insulating body, and a plurality of probes are arranged in the insulating body. The probe usually has a circular sleeve, and a probe is slidably installed in the sleeve, and a spring is installed between the bottom of the sleeve and the probe, and the spring pushes the contact end of the probe against the outside of the sleeve. The electrical connection of the probe is realized by abutting the probe against the inner wall of the bushing. When the probe is pressed into the bushing due to external force, the probe abuts against the inner wall of the bushing to achieve electrical connection. These probe connectors have been described in documents such as Taiwan New Patent No. M241848 and M332850.

In order to ensure the stable electrical connection of the probe connector, the probe bottom surface of the probe is generally designed as an inclined plane in the industry. When the probe is pressed down, the inclined surface compresses the spring in the sleeve to one side, and the probe is leaned against the inner wall of the sleeve to one side through the rebound force generated by the spring.
