Description

Изобретение относитс к электротехнике , в частности к средствам присоединени электропроводов к контактам , в которых удержание электропроводов обеспечиваетс за счет упругих усилий в воздействующих на электропровода элементах, и может быть использовано в разного рода электротехнических издели х (патронах , штепсельных разъемах и т.д.).The invention relates to electrical engineering, in particular, to means of connecting electrical wires to contacts, in which the electrical wires are held due to elastic forces in the elements acting on electrical wires, and can be used in various electrical products (cartridges, plug-in connectors, etc.) .

Известен контактный зажим, в котором присоедин емый электропровод вводитс в зазор между наклонной поверхностью контактной вставки и подвижным подпружиненным элементом A contact clip is known in which a connected electrical wire is introduced into the gap between the inclined surface of the contact insert and the movable spring-loaded element.

Известный зажим характеризуетс низкой надежностью закреплени электропровода .The known clamp is characterized by a low reliability of fixing the electric wire.

Известен также контактный ажим, содержащий опорный элемент,- с которым боковой поверхностью взаимодействует присоедин емый электропровод, изогнутую пружину, один конец которой воздействует на боковую поверхность закрепл емого электропровода с противоположной опорному элементу стороны , фиксиру электропровод. Другой конец пружины оперт на элемент зажима , при этом изогнута часть пружины расположена между элементами, контактирующим с ее внутренней и внешней сторонами 12J.Also known is a contact clamp containing a supporting element, with which a connected electric wire connects with a side surface, a bent spring, one end of which acts on the lateral surface of the fixed electric wire with the side opposite to the supporting element, fixing the electric wire. The other end of the spring is supported on the clamping element, while a part of the spring is bent between the elements in contact with its inner and outer sides 12J.

Недостатком этого зажима вл етс относительно невысока надежность закреплени электропровода в контактном зажиме.The disadvantage of this clip is the relatively low reliability of fixing the electric wire in the contact clip.

Цель изобретени - повышение надежности закреплени электропровода в контактном зажиме и устранение The purpose of the invention is to increase the reliability of fixing the electrical wire in the contact clip and to eliminate

10 возможности перекусывани электропровода .10 possibilities of cutting the electric wire.

Поставленна цель достигаетс тем, что контактный зажим, содержащий опор15 ный дл электропровода элемент, пружину с фиксирующим электропровод элементом и опорные элементы дл пружины, снабжен направл ющим пружину элементом , образующим с опорным элементом This goal is achieved by the fact that the contact clip containing the element supporting the electric wire, the spring with the fixing electric wire element and the supporting elements for the spring is equipped with a spring guide element forming with the supporting element

20 зазор переменной ширины, узка часть которого служит дл ввода в эаэор конца закрепл емого электропровода, а фиксирующий электропровод элемент пружины установлен в зазоре перемен25 ной ЬШрины с возможностью взаимодействи его с направл ющим элементом.20 is a variable width gap, a narrow part of which serves to insert into the eaor the end of the fixed electric wire, and the spring fixing electrical wire element is installed in the variable gap of the width with the possibility of its interaction with the guide element.

При этом пружина может быть выполнена в виде проволочного стержн , взаимодействующего с направл ющим In this case, the spring can be made in the form of a wire rod interacting with the guide

30 element side surface. In addition, the locking element of the spring can be made flat. FIG. Fig. 1 shows the construction of the proposed contact clip by the example of a receptacle (with the cover removed), front view; 2 is the same, top view (section. A-A in FIG. 1); in fig. 3 - pin clip, front view; in fig. 4. Same, side view; in fig. 5 - U-shaped pro-spring, front view; in fig. 6 - the same, top view; in fig. 7 shows the design of a contact clip in which a spring in the form of a straight wire rod is used, front view; in fig. 8 the same, side view; in fig. 9 shows the design of a contact clip using the example of a cartridge for fluorescent lamps, in which flat springs with flat fixing elements are used, viewed from the front; in fig. 10 - the same, side view; in fig. 11 shows the construction of a contact clip, in which an i-shaped spring plate with two limbs is used, a side section view; in fig. 12 - the same, front view. The contact clip comprises a housing in which the contact elements 2 are bent at one end 3. The surface 4 of each contact element 2 performs the function of a support element for the electric wire. Each contact element 2 (FIGS. 2 and 9) has a bending section 5, blocking the corresponding opening 6 in the housing 1, which serves to insert the plug pin into the socket (Fig. 2) or the legs of the socket of the non-centric lamp in the cartridge (Fig. 9 ). The guiding element 7 for the spring 8 is the inner surface of the bent end 3 of the contact element 2 (Fig. 2, 8 and 11) or the protrusion in the housing 1 (Fig. 9). The guide element 7 for the spring 8 with the supporting element 4 for the electric wire creates a gap 9 of variable width. Spring 8 (Fig. 5 and 6) is made of wire and has a U-shape. One of the locking electrical elements 10 of the spring 8 is installed (Fig. 2) in the gap 9 of variable width with the ability to interact with the guide element 7. The second end of the spring 8 abuts against the bottom of the corresponding groove 11 of the housing 1 (Fig. 2). The spring 8 of FIG. 7 is made in the form of a straight wire rod, in which the function of the electrical retaining element 10 is performed by its middle part, which interacts with the guide element 7 with its lateral surface. Each end of this spring 8 rests on a corresponding supporting element made in the form of a protrusion 12 of the housing 1. The springs 8 of FIG. 9 are each flat and each have an end edge 13 which serves as a flat locking electrical conductor of the element 10. The second end of each of these springs 8 rests on a corresponding supporting element, made in the form of a protrusion 14 in housing 1 (Fig. 9). In the contact element 2 of FIG. 1 3 and 4, a cut-out 15 and a window 16 are made, as shown in FIG. 1 - slot 17; in FIG. 11 and 12, an opening 18. In the side surface of the housing 1 (Fig. 10), windows 19 and 20 are provided, and in case 1, the recesses 21 and 22 communicate with the windows 19 and 20, respectively. A window 23 is also made in the housing 1 (Fig. 11). The electric wire is fixed in the contact clip as follows. Using a tool, such as a screwdriver blade, squeeze the locking electrical wire element 10 of the spring 8 through the notch 15 in the contact element 2 (Fig. 1); in the middle part of the spring 8 through the slot 17 in the contact element 2 (Fig. 7); through the window 19 in the side surface of the housing 1 and the recess 21 in the housing 1 (Fig. 9 and 10) and the window 23 in the housing 1 (Fig. 11), Then the end of the electric wire is brought into the gap 9 of variable width from the narrow part of it with the surface 4, which performs the function of a support element for the electric wire through the window 16 in the contact element 2 (FIG. 1), through the window 20 in the side surface of the housing 1 and the recess 22 in the housing 1 of FIG. 9 and 10), through the hole 18 in the contact element 2 (Fig. 11), after which the tool is removed. The use of the proposed contact clip eliminates the possibility of cutting the electric wire in the case of using a flat spring, since the impact on its side surface by the sharp edge of the spring is reduced; reduces the labor intensity of manufacturing, especially in the case of jMoro wire rod used as a spring, simplifies the assembly process.
