FORK WITH PRESSED LOCK

The proposed product relates to electrical engineering and can be used in electrical connectors. The plug with a push lock is designed to make introductory electrical connections while ensuring a secure fit with the cable outlet in the connected position.

Known electrical connector, consisting of a plug, on the body of which is located a sleeve with a part of the locking device placed on it, made in the form of a thread. The sleeve is mounted on the housing with stops installed on the spring and included in the conical holes and groove diametrically located on the housing. The spring is fixed to the sleeve using checks through coaxial holes located at the ends of the spring. The connector is disassembled manually by rotating the nut until the outlet housing completely leaves the plug housing, on which the nut with the sleeve is placed. Semi-automatic dissection is carried out thanks to the force applied to the additional locking device. For this, the pin is pulled out of two coaxial holes located at the ends of the spring, which, when straightened, releases the stops from fixing in the conical holes and the groove of the housing, and under the action of the dismemberment force, the sleeve comes off the housing due to its rigid connection with the nut. The connector is disintegrated without affecting the main locking device, consisting of a nut and a thread made on the sleeve. The device provides the ability to dismember the connectors both manually and semi-automatically at any speed. [RU 515196, H01R 13/52, publ. 05/25/1976] [1]

The disadvantages of this analogue is that the electrical connector has a complex structure.

The closest analogue in technical essence is the plug ШЩ4х60-В made by ZAO Electrozemyot Plant CJSC, consisting of the external and internal parts of the housing, the hinge cover and contacts. Fixing the plug when connecting to the socket housing of the cable ШК4х60-Р is carried out by engaging the hinged cover of the plug by the tide-protrusion on the socket body. [http://www.elconnect.ru/production/connect/common-industrial/hksh/] [2]

The disadvantages of this analogue is that the presence of a hinge cover on the plug makes it impossible to connect it to a cable outlet that also has a hinge cover, and therefore the manufacturer replaces the latter with a tide-tab on the housing of the cable outlet. This leads to a decrease in the degree of protection of the cable socket, since the lively contact sleeves of the socket remain uncovered, while only the contacts of the plug that are not energized are covered with the hinged cover of the plug. This electrical connection is fixed due to the hinge cover of the plug, which engages with the tide-protrusion on the socket body. This connection is not reliable, as the cable rises when the cable is jerked and the electrical connection of the plug to the outlet may break.

The objective of the proposed utility model is to create a plug that provides security and reliable fixation in the electrical connection "plug-socket".

The technical results of the proposed technical solution are to ensure reliable fixation of the plug-socket electrical connection, excluding spontaneous disconnection, the possibility of placing individual grounding contacts.

The indicated result is achieved by the fact that in the plug with a push lock containing a housing, an insulator and contacts installed inside the housing, according to the claimed utility model, a niche is made on the housing in which a push lock is located, consisting of keys and hooks mounted on the axis and equipped with a return spring. The hook can be made in the form of an angled inclined protrusion. A grounding contact group is located in a niche for accommodating a push lock.

The use of a push-in clamp in the plug allows the use of a hinged protective cover on the return cable socket that automatically closes the energized contacts, which increases the degree of safety during operation of the input connection. The use of a push lock also completely eliminates the spontaneous disconnection of the connectors without appropriate human actions, since it is possible to disconnect such a clutch only by pressing the lock button and releasing the hook in the form of an angled inclined projection. The lock works on the principle of ratchet. In the process of articulation, the edge of the socket presses on it, it deviates downward, turning around its axis, allowing the socket to slide on the plug with a push lock. When the socket is fully pushed, the latch, under the action of its return spring, returns to its original position, locking the reverse stroke of the socket. The retainer hook abuts against the rear end of the outlet and reliably fixes the joint. It is possible to pull out the socket only by tilting the latch, pressing the latch key and turning it around its axis, overcoming the resistance of the return spring. To place the latch in the inventive product provides a special niche. In it, if necessary, it is possible to place an additional grounding contact group. This ensures reliable fixation of the plug-socket electrical connection, eliminating spontaneous disconnection and the possibility of placing individual grounding contacts.

A plug with a push pin is illustrated in the drawings, in which Fig. 1 shows a schematic connection of a plug with a push pin and a socket, and Fig. 2 shows a sectional view of a plug with a push pin and a socket.

The plug with a push lock includes a housing 1 (Fig. 1, 2), an insulator 2 mounted on the contacts 3 inside the housing 1. A niche 4 is made in the housing, in which a push lock 5 is located, consisting of a key 7 mounted on an axis 6 and a hook 8. the latch is equipped with a return spring 9 (Fig. 2). A grounding contact group 10 is located in a niche for accommodating a push lock.

A fork with a push lock works as follows. To connect the consumer of electricity, a plug with a push lock is connected to the socket 11. The cover 12 of the socket 11 is deflected, and the plug with a push lock is pushed onto the socket 11. The lower edge 13 of the socket 11 touches the protruding hook 8 of the clamp 5. The outer side of the hook 8 of the clamp 5 has an inclined the surface, therefore, when pressed, the latch 5 deviates downward, turning around its axis 6 and twisting its return spring 9. Having deflected, the latch 5 frees up the passage for further sliding of the socket 11 onto the plugs at with a push clamp. When pushing, the catch 8 of the latch 5 slides along the bottom surface of the socket 11. The socket 11 is pushed onto the plug with the push lock to the stops 15 of the socket 11. After the socket 11 is completely pushed onto the plug with the push lock, the clamp 5 returns under the action of its spring 9 in the initial position, locking the end face 15 of the socket 11 hook 8 as a ratchet. The socket 11 is securely engaged with the plug with a push lock. To disengage the socket 11 and the plug with the push lock, press the button 7 to tilt the lock 5 down, while the lock 5 rotates around its axis 6, twisting the spring 9, the hook 8 of the lock 5 is lowered and releases the rear end 15 of the socket 11. The socket 11 is removed from the plug with the push lock, while the hook 8 slides along the lower contour of the socket 11 body. When the socket 11 is completely removed from the plug with the push lock, the clamp 5 returns to its original position under the action of the return spring 9, and the cover 12 of the socket automatically ski rotates under the action of its spring 16 and covers the contacts under voltage, preventing electric shock to the user. In the manufacture of a fork with a push-lock, two large and labor-consuming parts, the “internal fork body” and “fork cover”, are excluded and functionally replaced by the body 1 and the small-sized part — the clamp 5, which greatly simplifies the manufacturing process of the fork with a push lock and reduces the cost of the design as a whole .
