| Description: |
|---|
| The steel head of the fuze contains a springloaded inertial-type plunger assembly containing the rotor-mounted firing pin. The firing pin is retained in the unarmed position by spring-loaded safety pins (not shown in illustration). The plunger assembly is contained in a steel housing and uses one compression spring. A detonator is located in a holder just forward of the plunger assembly. Bore safety is provided by a spring-loaded slider located between the detonator and the booster lead charge. The slider functions as an interrupter in the unarmed position, but also carries a tetryl charge, aligned when the slider moves to the armed position, so the slider charge becomes a part of the detonator train. A tetxyl booster charge is retained in the base by a brass cup threaded over the fuze body. In fuze M62, the plunger assembly is contained in a light brass housing and uses two small compression springs. In fuze M62A1, a different detonator is used. |
| Use: |
|---|
| Base detonating fuzes of the M62 Series are the non-delay type. M62A1 is used with 75mm and 105mm recoilless rifle with HEAT and HEP cartridges. The M62A2 is used with 165mm guns with HEP cartridge. (The illustration shows the M62A2). |
| Functioning: |
|---|
| Centrifugal force withdraws the safety pins to permit the rotor to turn and align the firing pin with the detonator. Centrifugal force also moves the slider transversely against the slider spring to align the slider charge between the detonator and the booster charge. Rotational speed required for slider arming is not less than 2350 rpm nor more than 3650 rpm. During projectile flight the firing pin is held out of contact with the detonator by the plunger assembly spring. Upon impact, the inertia of the plunger overcomes the spring and drives the firing pin into the detonator to initiate the explosive train to the projectile. |
