Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of electric percussion bullet primer 15 with metal fuse is arranged on the bottom of bullet case 13, including electric ignition head 1, conductor cover 3, spring 4, conductor rod 5, electric primer base Seat 6, first conductive ring 7, electric shock needle 8 and second conductive ring 9. The electric primer base 6 is cylindrical, and the bottom is provided with a circular groove. The circular groove is provided with a cable passage 10 that runs through the center of the circle. The center of the electric primer base 6 is provided with a second-order stepped hole. The diameter of the second-stage stepped hole decreases from top to bottom, the larger diameter is the first-stage through hole, and the smaller diameter is the second-stage through-hole, and the two wire through-holes 11 are symmetrically distributed on both sides of the second-stage stepped hole. The first conductive ring 7 is arranged in the bottom circular groove of the electric primer base 6, and the conductor rod 5 includes a shaft and a round cap fixedly connected to the top of the shaft, both of which are integrally manufactured. The circular rod cap is located at the bottom of the first-stage through hole, and the shaft extends into the second-stage through-hole. There is a wiring hole 12 perpendicular to its central axis on the shaft, and the conductor cover 3 is fixedly connected in the first-stage through-hole. A spring 4 is provided between the conductor cover 3 and the conductor rod 5 . The conductor rod 5 can move along the axis of the second step hole of the electric primer base 6, and after the conductor rod 5 compresses the spring 4, it contacts with the conductor cover 3 and conducts electricity. The electric ignition head 1 is arranged in the propellant 14 above the conductor cover 3. One pole of the electric ignition head 1 is connected to the first conductive ring 7 through a wire 2 through a wire through hole 11, and the other pole is divided into two paths, and one pole passes through Conductor 2 is connected to conductor cover 3, and the other way passes through conductor 2 through another conductor through hole 11, wiring slot 10 and wiring hole 12, and is connected with the conductor 2 connecting electric ignition head 1 pole. The two poles of the electric ignition head 1 are short-circuited by the wire 2 in the initial state. The electric shock pin 8 fixed on the end face of the bottom socket of the bolt is located under the electric primer base 6, the second conductive ring 9 is set on the top of the electric shock pin 8, and the two are not in contact, and the two poles of the power supply are connected to the second conductive ring 9 and the electric shock pin respectively. 8 connected.

The central axis of the wiring hole 12 on the body of the conductor rod 5 is coplanar with the wiring slot 10, which is convenient for wiring.
