An insertion gap is formed between the locking piece portion and the female metal inner shell. When the anti-dropping insertion ring of the male metal shielding shell is inserted into the insertion gap, the positioning convex ribs on the outer surface of the anti-dropping insertion ring are pressed into the locking groove on the inner wall of the locking piece portion from the inside to the outside to lock it. The anti-dropping insertion ring is subjected to the extrusion force from the outside to the inside of the locking piece portion, which drives the inner wall of the anti-dropping insertion ring to squeeze and wrap the outer surface of the female metal inner shell.

The utility model discloses a short body connector, which comprises a metal shell, an insulating rubber core and a plurality of terminals, the insulating rubber core comprises an insulating base and a lingual plate, the metal shell is fixedly connected with the insulating base positioned at the tail part of the metal shell, the lingual plate is positioned inside the metal shell, and the terminals are arranged in terminal mounting grooves arranged on the lingual plate. According to the utility model, the length from the tail part of the insulating base to the head part of the metal shell is 8-10mm, so that the overall length of the connector is greatly shortened, the metal shell adopts a reverse elastic sheet design, and the free end of the reverse elastic sheet faces the tail part of the metal shell; therefore, a good locking force between the reverse elastic sheet on the metal shell of the connector female seat and the connector male head can be ensured, the plugging force is improved, and the problem that the connector male head cannot be locked is avoided.

An electrical connector combination includes a board-end connector and a line-end connector that can be docked. The board-end connector includes a first base and a plurality of first terminals. The first base includes a base, two opposite first side walls and a first buckle portion. The base and the two first side walls form a docking space. The first buckle portion has a buckling protrusion that protrudes into the docking space. The first terminal is fixed to the base and includes a contact portion that protrudes into the docking space and a pin extending from the base. The line-end connector includes a second base and a plurality of second terminals. The second base is provided with a second buckle portion that buckles with the first buckle portion. The first base further includes a second side wall. The second side wall is integrally connected to the same side of the base and the two side walls. The second side wall is integrally provided with a first buckle portion. The second base is provided with a second buckle portion that cooperates with the first buckle portion. Compared with the prior art, the board-end connector and the line-end connector of the present invention have buckle portions, so that the two connectors have buckle structures on different sides, increase the plug-in force, and reduce the risk of improper disconnection.

The application provides an elastic needle which is used in cooperation with a base, the elastic needle is assembled in a mounting hole of the base, the elastic needle comprises a needle tube, a plurality of split grooves are formed in the tube wall of the needle tube along the axial direction, the split grooves divide the tube wall of the corresponding area into a plurality of elastic arms which can produce radial elastic deformation, when the needle tube is assembled in the base mounting hole, the tube wall is in elastic contact with the inner wall of the base mounting hole through the radial elastic deformation of the elastic arms. The elastic needle of the application, the needle tube is in elastic contact with the inner wall of the base mounting hole through the elastic arms, so that the insertion and extraction force of the elastic needle in the mounting hole is increased, and the elastic needle is prevented from being loosened or popped out from the mounting hole in harsh working conditions such as vibration. Meanwhile, the split grooves are designed to make the tail part of the needle tube have radial deformation capacity, and prevent the insertion and extraction force from being too large.
