Order 3G1006 A6 B6 5. Description of the invention (7) Insert the protection plug 1 into the slot 4 8. (Please read the notes on the back and then write this page) In the first embodiment of the protective plug 1 (Figures 1 to 4), the lug 1 1 presses the hook 6 that fixes the overvoltage suppressor 3, 7. As shown in FIG. 4, and contact the pole side 28 of the overvoltage suppressor 3, the overvoltage suppressor 3 is grounded. The overvoltage suppressor 3 is pressed by the elastic conductor contact pieces 1 3, 1 4 against the terminal 11 connected to the convergent ground, so that the safe contact between the pole side 28 of the overvoltage suppressor 3 and the terminal 11 is achieved. When the protection plug 1 is pulled out of the connector or the circuit breaker contact row 4, the latch hooks 6, 7 are engaged again after the one pole side 28 of the overvoltage suppressor 3, and they are fixed to the protection plug 1 again In the shell 2. In the second embodiment of the protective plug (FIGS. 5 to 11), the lugs 1 1 cover half of each front face 10 of the protective plug 1 so that the slots 42 between the lugs 1 1 extend at Protect the plug 1 on the center of the longitudinal axis 9 and receive the guide tabs 3 5 ° of the latch hooks 6 and 7 and the center tab 3 3 ° In order to better guide the lugs 1 1, two additional guide tabs are provided 4 4 is in front of the narrow side 4 5 10. Central Bureau of Standards of the Ministry of Economic Affairs: Printed by the Industrial and Consumer Cooperatives in the third embodiment (Figures 12 to 16), when the protective plug 1 is inserted into the insertion slot 48, the lug is pressed against the shoulder 2 Below 4, as shown in Figure 12. To facilitate insertion, the lug 1 1 is slightly bent at the front 46 in this embodiment. In the fourth embodiment (FIGS. 17 and 18), the lug 11 provides a shorter length than the previous embodiment. Since the lug 11 in this embodiment only needs to be connected to the sheet metal part 5 0 Electrically connected. In order to guide the lugs 1 1, the guide angles 5 3 are each provided on the longitudinal side 8 of the housing 2. This paper is again applicable to the Chinese National Standard (CNS) f 4 specifications (210 X 2 mm) _ 82,3. 40,000 A6 B6 V. Description of the invention (8), so that in the insertion slot 48, the lug 11 of the convergent ground connection 5 is arranged between the lead angle 53 and the sheet metal portion 50. If the protective plug 1 is connected to the longitudinal side 8 side by side, a protective plug bank 31 is formed. The following briefly describes the overvoltage situation. If an overvoltage occurs, the overvoltage or overcurrent is conducted on the cable wires 3 8 and 3 9 respectively, insulation displacement contacts 4 0 and 4 1, fork contacts 4 7, conductor contacts 1 3 and 1 4, and melting beads 3 0 to one side 29 of the overvoltage suppressor 3. The overvoltage suppressor 3 filled with inert gas ignites, and the overvoltage is conducted to the other pole 2 8 of the overvoltage suppressor 3, and the overvoltage suppressor 3 is electrically connected to the convergence ground connection 5. Therefore, the overvoltage is conducted between the fork contact 41 and the convergent ground connection 5 to the mounting frame 3 6 ° connected to a ground. In the case of permanent ignition of the overvoltage suppressor 3, the melting beads 30 will be generated due to Heat to melt, so that the elastic short-circuit bridges 25, 26 contact the lug 11 of the convergence ground connection 5 or the sheet metal part 50 connected to the convergence ground connection, and at the same time short-circuit the overvoltage suppressor 3 . Thus, damage to the protection plug 1 can be avoided.
