Description

Известны распределители зажигани дл двигател внутреннего сгорани , содержащие полый корпус с кольцевой проточкой в которой размещена неподвижна пластина прерывател и пружинный зажим L -об разной формы l}.The ignition distributors for an internal combustion engine are known, comprising a hollow body with an annular groove in which a fixed chopper plate and a spring clip L are of different shape l}.

Однако они имеют сложную конструкцию и технологию.However, they have a complex structure and technology.

Предлагаемый распределитель отличает с от известных тем, что конец пружинного зажима укреплен на неподвижной пластине , например, винтом, а пластина снабжена глухим пазом, секущим её по хорде, дл образовани упругого ушка.The proposed distributor differs from those known in that the end of the spring clip is fixed on a fixed plate, for example, with a screw, and the plate is provided with a blind groove intersecting it along the chord to form an elastic tab.

Такое выполнение распределител позвол ет упростить его конструкцию и технологию по сравнению с известными,This embodiment of the distributor allows to simplify its design and technology in comparison with the known,

На фиг, 1 схематически изображен предлагаемый распределитель; на фиг, 2 - мо-дификаци неподвижной пластины распределител , изображенного на фиг, 1, вид сверху: на фиг, 3 - модификаци пружины, показанной на фиг, 1, вид сбоку,Fig, 1 schematically shows the proposed distributor; FIG. 2 shows a modification of the fixed plate of the distributor shown in FIG. 1, top view: FIG. 3 shows a modification of the spring shown in FIG. 1, a side view,

Полый корпус 1 распределител имеет кольцевую проточку 2 клинообразной формыThe hollow case 1 distributor has an annular groove 2 wedge-shaped

в которойрасположена неподвижна пластина 3. На пластине смонтирован контактный узел (на чертеже не показан). Область 4 пласТ1ШЫ имеет форму, соответствующую форме проточки в корпусе распределител . Диаметрально противоположно этой области размещен пружинньш зажим 5 L -образной формы из пружинной стали. Один конец зажима при монтаже ввод т в зацепление с выступом 6, образованным на корпусе распределител , а другой креп т на пластине винтом 7.in which a fixed plate 3 is located. A contact assembly is mounted on the plate (not shown in the drawing). Area 4 PlasT1SHY has a shape corresponding to the shape of the groove in the distributor housing. Diametrically opposite this area is placed spring clip 5 L-shaped form of spring steel. During mounting, one end of the clamp is meshed with the protrusion 6 formed on the distributor case, and the other is attached to the plate with a screw 7.

Взаимное расположение отверсти на зажиме и винта выбирают таким , чтобы при креплении зажима винтом к пластине создавалось усилие, прижимающее пластин как вниз, так и поперечно, обеспечива механический контакт области 4 пластины с проточкой и надежное крепление пластины в корпусе распределител ,The mutual arrangement of the hole on the clamp and the screw is chosen so that when the clamp is screwed to the plate, a force is created that presses the plate both down and transversely, ensuring the mechanical contact of the plate area 4 with the groove and reliable fixing of the plate in the distributor case,

Claims

In the modification of the embodiment shown in FIG. 2, the plate has a deaf groove 8, thereby forming an elastic eye 9, which is part of the plate. The region located diametrically opposite to the elastic eyelet, as well as the area 4 of the modification, shown in FIG. 1, has the forms corresponding to the form of sharpening in the distributor case (wedge form). The shape of the wedge is also the edge of the plate, forming an elastic eye. The diameter of the part of the plate, located between points aa, with the exception of the part forming the elastic ear, is less than the maximum diameter of the plate, which ensures convenient mounting of the plate in the housing. When assembled, at first the eye 9 is bent towards the center to reduce the overall diameter of the plate. The plate is installed in the groove, after which a taper screw is inserted into the blind groove 8, during rotation of which the elastic eye 9 is bent outwardly, whereby the plate is fixed in the sharpening. A conical screw, which is inserted into the blind groove, can also be used to secure a spring clip. The combined action of the spring clip and the elastic tab provides reliable mounting of the plate in the housing. Fig, 3 shows one of the possible modifications of the spring clip. This modification differs from the clamp shown in FIG. 1 in that it has a V-shaped bend on one of its arms, which enhances the spring action. Pinnacle contacts (not shown in the drawing) are mounted in the usual way on a plate directly or by means of an intermediate plate, which provides in the usual way adjustment of the ignition advance. A camshaft (not shown) passes through the central hole of the plate, interacting with the contacts, ensures the opening of the current in the primary circuit of the ignition system. On the case, the distributor cap is mounted in the usual way, equipped with high voltage leads. With the slider and the cover, the high voltage is distributed to the spark plugs of the engine. DETAILED DESCRIPTION An ignition distributor for an internal combustion engine comprising a hollow body with an annular groove in which a fixed plate of the front panel and a spring clip of b-shaped, are placed, characterized in that, in order to simplify the design and improve processability, the end of the spring clip is fixed on the fixed plate e.g. a screw, and the plate is provided with a blind groove intersecting it along the chord to form an elastic tab.
