The invention relates to the technical field of power supply equipment, and discloses firm-plugging electric power supply equipment which comprises a charging gun body, a charging interface is formed in the charging gun body, a connecting port is formed in the charging interface, a charging needle is arranged in the connecting port, and the charging needle comprises a needle head, a needle body and a needle base. The needle seat is arranged in the charging interface, and the needle body is arranged in the connecting port; through the arrangement of the expandable reinforcing sleeve, the unexpanded reinforcing sleeve does not make contact with the inner wall of the charging female base, so that the friction force of the charging interface in the insertion process is reduced, abrasion generated in the insertion and extraction process of the charging interface and the charging female base is reduced, and the situation that the charging gun is not firm in connection after long-term use is avoided; the firmness after long-term use is guaranteed, the pressure between the expanded reinforcing sleeve and the charging female seat is large, the static friction force is also large, the firmness of mutual connection is guaranteed, and the charging gun is prevented from loosening in the charging process.

    本发明涉及供电设备技术领域,公开了一种插接牢固的电动供电设备,包括充电枪本体,所述充电枪本体上设置有充电接口,所述充电接口上开设有连接口,所述连接口内设置有充电针,所述充电针包括针头、针身和针座,所述针座设置在充电接口的内部,所述针身设置在连接口内;本发明通过可膨胀的加固套的设置,未膨胀的加固套不会与充电母座的内壁相接触,使得充电接口的插入过程摩擦力减小,减少了充电接口和充电母座插拔过程中产生的磨损,避免长期使用后充电枪连接不牢固,保证了长期使用后的牢固性,膨胀后的加固套与充电母座之间的压力较大,静摩擦力也较大,保证了彼此连接的牢固性,以防止充电过程中充电枪松动。
