Description

The closest to the proposed one is between the plate and the extreme point of this arc, and the stroke is the contact of the base of the fire brigade selected by the prototype. Optical fire detector - but smaller than the diameter of its cap. zlektronny MP o 212-445 Passport 4371-006- In the proposed contact device for 12215496-00 PS; TU 4371-006-12215496-00) | that the base of the removable fire detector due to made for a detachable connection with the corresponding application of a special petal molding, and a mushroom-shaped contact on the detector, and which also has a ratio of the sizes of the elements of the connector - an electrically conductive and elastic plate from a protruding connection is provided more reliably by eleps on the ends of this plate and with the hole for the crypto-critical and mechanical connection of the detector from its ball to the insulating base of the base, as well as with the zoya, with small forces applied to the hole on the edge of this plate for the screw parts during connection or disconnection of the notification- connection with conductors and loop elements of the watch with its base. of a fire alarm on a plate with an open On Fig. 1, the contact of the base with a removable slot is made of a petal that has the shape of a fire alarm. of a security pawn, the round head of which is connected to Fig. 2 shows a section along the line A-A through the rectangular body of the petal with the small base of the contact base of the removable fire alarm. of the elastic arm, which has the shape of a trapezoid, is large. Fig. 3 shows a section along the line A-A, the base of which is connected to the plate, in the middle of the contact of the base, when the contact of the removable rectangular body of the petal is established, the bend of the fire alarm is made. plane of the petal. The plate has a rectangular shape, and the bend on the rectangular body of the petal is made for a plug-in connection with a corresponding angular finish, in addition, the petal has an additional mushroom-shaped contact 1 (see Fig. 3) on the cervical fold line on the elastic shoulder, which has the shape of a pin, and which has an electrically conductive and elastic trapezoid. This additional bend on the elastic shoulder of plate 2 (see Fig. 17 and Fig. 2) with a projection Z on makes the bend angle in the middle of the rectangular body of the end of this plate 2 and with the hole 4 for the petal element more obtuse. 6 fixing plate 2 to the insulating base of the base

The disadvantage of the known contact is also that 5, as well as with the hole 7 on the edge of this plate 2 for when installing the mushroom-shaped contact of the alarm connection with the conductors and the detector element in the shaped slot on the plate, we will not provide the fire alarm loop, the nut of which means the proper fixation of this contact, because it moves in the niche 8 under this hole 7. On the plate 2, the double fold of the petal makes, during installation, the petal 10, which is made with an open slot 9, the detector is a plane with a round platform that has the shape of a chess pawn , the round head 11 is not only tangential to the cap of the corresponding contact, which is connected through the rectangular body 12 of the detector petal, but also almost parallel to the plane with the small base of the elastic arm 13, which has a shadow. Therefore, proper fixation of the trapezoid shape is not ensured. Spring arm 13 with its large detector in the base. the base is connected to plate 2. On the right angle

The invention is based on the task of bending the petal 10 to the hinged body 12. To ensure the reliability of the connection of the contacts of the base from the flap 10, it is shaped in such a way that the part with the corresponding contacts of the detector, due to the round head 11, remains parallel to the reliable fixation of the mushroom-shaped contact of the detector - the plane of the plate 2, and the bend on the second part of the watch with the elastic contact of the base. round head 11 and rectangular body 12 forming

The task is solved by the fact that the contact creates an arc (see Fig. 2 and Fig. 3) in the shape of the outer base of the fire detector, which is made for the side of the cap 14 of the corresponding mushroom-shaped connector with the corresponding mushroom-shaped contact 1, the height of this cap is 14 further away by the contact on the detector, and which has an electrode between plate 2 and the extreme point of this arc 15, and a conductive and elastic plate with protrusions on the end, the width of the rectangular body 12 is greater than the diameter of this plate and with a hole for attaching it to the 16 of the corresponding mushroom-shaped contact 1, but the lation base of the base, as well as with a hole on the edge smaller than the diameter of its cap 14. On the insulating plate of this plate for the screw connection with the conductive base of the base 5, niches 17 are made for protrusions 3, and cams and loop elements fire alarm- element 18 of fixing these projections 3. tion on the plate with an open slot made The contact of the base of the fire alarm operates a petal shaped like a chess pawn, round such that another On the insulating base of the base 5, the round head of which is connected through the rectangular body of the form along the outer radius, the plastic petals are placed, on which the fold is made, with the small plate 2. The protrusion Z plate 2 is fixed in the niches 17 by the base of the elastic arm, which has the shape of a trapezoid, thanks to the element 18 on the insulating base of the base 5, the large base of which is connected to the plate, which, with the help of the hole 4, the fastening element 6, differs in that the round head of the petal plate 2 is fixed on the insulating base with a larger cap of the corresponding mushroom-shaped conta-base 5. ktu, in addition to the petal formed in such a way that when the detector is connected to its base 5, the round head or part of it remains, contact 1 enters the round hole from the round head parallel to the plane of the plate, and the bend on the edges 11 of the petals 10. The cap 14 of contact 1 acts on a rectangular the body of the petal forms an arc-shaped round head 11, which moves away from the outer side of the cap of the corresponding mushroom wall 2, until the leg 16 of contact 1 enters the bottom contact, the height of this cap is greater than the cross-section of the rectangular body 12 of the petal 10. Due to the fact that the diameter of the cap 14 is smaller than the diameter of the circular plate 2 to the extreme point of the arc 15 is less than the vertical head 11, and the opening of the rectangular body 12 of the heel of the cap 14, elastic electric is achieved and the blade 10 has a width that is greater than the diameter of the leg mechanical connection of the contact 1 of the detector with the plate 16 and less than the diameter of the cap 14 of the contact 1 by the alarm 2 of the contact of the base 5. of the detector, a convenient mechanical connection is provided. Due to the use of special molding of the detector with the base 5. Contact 1 continues with the petals 10, as well as the ratio of sizes to move along the rectangular body 12 of the petals 10 of the elements of the detachable connection, it is ensured in the direction of the elastic arm 13 until the petal 10 a more reliable electrical and mechanical connection fixes the position of the contact 1, thanks to that the detector with the base 5, with small efforts that the arc 15 of the petals 10 covers the cap 14, the contacts are applied to the parts during connection or connection 1. Due to the initial molding of the petal, the disconnection of the detector from its base 5. 10, when in the absence of contact 1 the distance from i YN and EN Y: s y vo dentin pinannh - vh BU Bi What would be pu ;
