SI24169A - Lock of a detachable module in a socket of an overvoltage device - Google Patents

Abstract

The technical problem that is solved with the present invention is a structural locking solution for the discharge module, which protects against modulating the module from the base of the overvoltage protection. The essence of the locking outlet module at the foot of the overvoltage protection according to the invention is that the locking button of the symmetrical assembly is pulled through the specially shaped recesses when the module is installed and in the final position it is stuck in a semicircular shaped horizontal part. By simultaneously moving the buttons, the "locked" or "unlocked" status is shown on the outside of the module.

Description

LOCKING MODULE LOCK UNDER UNDERGROUND PROTECTION

The field of technology

The invention belongs to the field of electronic surge protector devices, more specifically to the area of a mechanism that allows locking of a protruding module at the base of the surge device.

A technical problem

A technical problem that is solved by the present invention is a structural solution to the locking of the protruding module, which allows protection against the module being dropped from the base of the surge protector. The design solution must protect the failure or movement of the module after insertion into the base, which may occur under the influence of vibrations during transport or general handling. Mechanical fallout protection must also work in lightning strikes when the electromagnetic forces are so large that they eject the module from the base.

The prior art

There is a known solution for the mechanical protection of a module in patent DE102008017423A1, where the solution is based on a cartridge of a specific shape that is inserted into the base of the surge protector. In its seat, the insert rotates. When there is no module in the socket, the cartridge is oriented so that the module can be inserted freely into the socket. After inserting the module, in order to secure the position, locking the module in this position, rotating the insert so that its specific shape, due to the appropriate geometry on the module, does not allow the module to move in a vertical direction. The insert is rotated with a screwdriver. Re-enabling the module to move in the vertical direction is performed by the same procedures in reverse order.

In W02008009507A1, the solution relates to the use of a special wedge shape on a module, taking advantage of the flexibility of the plastic material and the inverted shape on the base, which accepts this wedge. When inserting a module into the footer '·· .....

overvoltage protection, the wedge-shaped part is automatically removed by friction to the inside of the module, where space is provided and as soon as the inverse shape at the base allows it to snap. This prevents the module from moving further in a vertical direction. When the plastic part is pressed on the side of the module, the wedge moves away from the position where the inverse shape of the base is located, thus enabling the module to move in a vertical direction without interruption.

Description of solution to a technical problem

The point of locking the protruding module at the base of the surge protector according to the invention is that the locking buttons of the symmetrical assembly, when installing the module, travel along a specially shaped recess and are locked in the end position in a semicircularly shaped horizontal part. But the simultaneous movement of the buttons shows the status "locked" or "unlocked" on the outside of the module.

The locking of the protruding module at the base of the surge protector according to the invention will be described below with the help of figures showing:

Figure 3b - unlocked status signaling

Figure 4a - base and module

Figure 4b - detail A

The present solution of the locking of the base 2 and module 1 is implemented by the characteristic construction of the locking system in module 1 and the characteristic retaining forms on the receiving walls of the base 2. The housing 1a of module 1 has a special barrier 1b on the longer side with an inner shorter side 1 b 'adjacent to outer side 1a '. In the slot formed by sides 1b and 1b 'is a plate 3 having a circular opening 3a on one side and an elongated oblique slot 3b on the other. A spring 6 is mounted between the side 1 b 'and the plate 3, which is clamped on one side to the slot 3b by the button 4' of the trigger 4, which has an external button 4 which is inserted into the groove 1a 'on the side 1a of the housing 1a. Spring 6 is · · ··· ··· on the other side, clamped with button 5 ′ of slider 5. On page 1c there is a mirror image of the * assembly described earlier.

The base 2 has a characteristic recess 2a in its inner part, having the upper portion 2a 'shaped like the upper portion of the letter V, which has a lower elongate recess 2a below, with semicircularly ended lateral sides. When module 1 is inserted into the base 2, the outer button 4 of the trigger 4 travels through the upper portion 2a 'of the recess 2a and lands in the semicircularly completed lateral side of the elongated recess 2a. At the same time, the button 7 'of the trigger 7 travels through the recess on the other side of the base. When the 4 'and 7' buttons are in the semicircular portion of the recess 2a, the module is locked into the base, with the button 5 and on the other side of the button 8 moving the tile 3 in the "locked" position. Module 1 thus prevents movement in the vertical direction. The module can be pulled out of the base again by pulling it vertically on the sides of the button modules 5 and 8. When module 1 needs to be pulled out of the base 2, it is pulled up, with the help of the spring 6 the tile 3 returns to its original state. The buttons 5 and 8 are moved in the reverse order as in the insertion.

The structural solution described above for the locking of the protruding module at the base of the surge protector solves the problem of uncontrolled movement of the module as well as the status indication.

Claims (1)

Patent claim The lock-out module lock at the base of the surge protector is characterized in that the lock of the base (2) and module (1) is made by the structural form of the locking system in the module (1) and the characteristic grooves on the receiving walls of the base (2); that the housing (1a) of module 1 on the longer side has a special barrier (1b) with an inner shorter side (1 b ') adjacent to the outer side (1 a'); that a tile (3) is provided in the slot formed by the sides (1b and 1b '), which has a circular opening (3a) on one side and an elongated sloping slot (3b) on the other; that a spring (6) is mounted between the side (1 b ') and the plate (3), which is clamped to one side in the slot (3b) by a button (4') of the actuator (4) having an external button (4), mounted in a groove (1a ') on the side (1a) of the housing (1a); that the spring (6), on the other hand, is clamped with the knob (5 ') of the slide (5); that on page (1c) is a mirror image of the assembly described above; that the base (2) in the inner part is characterized by a recess (2a) having an upper portion (2a ') shaped like the upper portion of the letter V having an elongated recess (2a) below, with semicircularly ended lateral sides; that, when inserting the module (1) into the base (2), the outer button (4) of the actuator (4) travels through the upper part (2a ') of the recess (2a) and lands in a roundly completed part (2a); that at the same time the trigger (7 ') of the actuator (7) travels through the recess on the other side of the base (2); when the buttons (4 'and 7') are in the semicircular part of the recess (2a), the module (1) is locked into the base (2), with the button (5) and on the other side the button (8) by moving the tile (3) put it in locked position; that module (1) is thus prevented from moving vertically.
