A method for making a bayonet connecting element for a connector, according to which a connecting element body, with a hollow cylindrical general shape is made. The method includes making a through bore by drilling a wall of the body of the connecting element, from the outer surface of the wall. The outer surface of the wall is machined around the bore so as to create a conical contact surface around the bore. A lug is inserted into the bore, from the outer surface of the wall, so that a head of the lug projects from the outer surface of the wall of the connecting element. The lug having a conical contact surface corresponding to the conical contact surface of the bore.

The invention relates to a locking system for connectors for connecting and locking a plug to its plug partner, comprising a primary lock formed by at least one bayonet ring with at least one control gate, coupled to a connector plug and designed for functional cooperation with at least one pin associated with the control gate on a connector mating plug, wherein the control gate has a Z-shaped course so that a two-stage movement kinematics of the primary locking is supported. Furthermore, the invention relates to a plug connection for making a detachable electrically conductive connection, comprising a connector plug and a connector mating plug with a locking system.

The utility model discloses an electrical connector for Christmas lamp trees which comprises an upper and a lower connecting base, first columnar electrodes and elastic devices are arranged in the upper connecting base, second arc-shaped electrodes are arranged in the lower connecting base, and the elastic devices cause the first electrodes to tightly abut against the second electrodes. The first columnar electrodes and the second arc-shaped electrodes form a point-to-surface contact, so that the reliability of electrical connection is increased greatly, allowing a Christmas lamp tree to be universal to high and low voltages. Moreover, sufficient contact between upper and lower layers and natural effect of the Christmas lamp tree can still be ensured even if the Christmas lamp tree is subjected to an external force, and multiple sets of first and second electrodes are electrically connected in one-to-one correspondence, leading to diversified functions of the Christmas lamp tree.
