, Description:Complete specification: The following specification particularly describes the invention and the manner in which it is to be performed. 
Field of the invention:
[0001] The invention relates to a fuel injector and particularly relates to a leak off connector of the fuel injector.

Background of the Invention:
[0002] A person skilled in art would be aware that many version of fuel injectors are already known. However, some basic components in a fuel injector are always present. Following are some of the basic components of any fuel injector known in the state of the art viz the injector body components, the magnet group components, electrical connector components, nozzle module components and the like. With regard to this disclosure we will specifically focus on the leak off connector provided in a fuel injector.
[0003] In conventional diesel injectors, leak-off connection is provided to drain the excess low pressure fuel back to the tank without leakage from leak-off joints of the injector. There are majorly three types of leak-off connections:
1. Fastener assembled with Banjo and Copper washer
2. Copper brazed type joint
3. Press fit with application of Loctite
[0004] However, these existing leak off connectors normally may pause multiple issues resulting in complexities. These designs themselves pause complexities and difficulties in manufacturing and even result in leakage through the leak off connection, while being heavy and increasing the weight of the injector. More importantly, the existing models demand considerable effort for assembly of the leak off connector, for instance the effort required to assemble and tighten a banjo leak off connector with bolts. Additionally the assembly may be made complex with commonly occurring missing of components or wrong components being used in the assembly. Moreover, there are multiple processes and complexity involved in the assembly of these existing connectors.
[0005] Therefore, there exists a need for a simplified leak-off connection designed for conventional injectors in order to reduce manufacturing complexity and provide ease of assembly, as described in this disclosure.

Brief Description of Drawings:
[0006] An embodiment of the disclosure is described with reference to the following accompanying drawings,
[0007] Fig. 1 illustrates a fuel injector, according to an embodiment of the present invention;
[0008] Fig. 2 illustrates a leak off connector of a fuel injector, according to an embodiment of the present invention; and
[0009] Fig. 3 illustrates a locking mechanism for a leak off connector of a fuel injector, according to an embodiment of the present invention.

Detailed description of the embodiments:
[0010] Fig 1 illustrates a fuel injector (10), according to an embodiment of the present invention. The fuel injector (10) comprises of at least an injector body (102) and the injector body (102) comprises of an interface (110) located at the operative top of the fuel injector (10). The interface (110) may be a stepped reamed or drilled hole on the injector body (102).
[0011] Fig. 2 illustrates a leak off connector (20) of the fuel injector (10), according to an embodiment of the present invention. Further, the leak off connector (20) comprises of a locking clip (106) located on a portion of the leak off connector (20).
[0012] Fig. 3 illustrates a locking mechanism for the leak off connector (20) of the fuel injector (10), according to an embodiment of the present invention. Accordingly, the interface (110) of the fuel injector (10) is adapted in such a way as to receive the leak off connector (20) using the locking clip (106).Additionally, the fuel injector (10) also has a groove (108) located in the interface (110). The groove (108) is located such that, when the interface (110) receives the leak off connector (20), the locking clip (106) snap fits into the groove (108).
[0013] In one embodiment of the invention, the single piece leak off connector (20) can be made of plastic or metal embedded with plastic. Additionally, the groove (108) acts as a provision for mounting O-ring for sealing low pressure leak off fuel to ambient conditions.
[0014] The leak off connector (20) as described in the disclosure is for a simplified leak off connection and designed for conventional injectors such that it aids in reduction of manufacturing complexity and ease the assembly processes like pipe bending, brazing, pressing, torqueing and so on, for instance the effort required for assembling and tightening banjo with bolt. The disclosed leak off connector (20) also have multiple advantages in addition to this. Most importantly, said leak off connector (20) can drastically reduce leakage through leak-off connection. This will also prevent the missing or wrong components being used, as is the common occurrence in case of copper washers, banjo bolt and so on. Moreover, the invention will drastically reduce the injector weight.
[0015] It should be understood that embodiments explained in the description above are only illustrative and do not limit the scope of this invention. Many such embodiments and other modifications and changes in the embodiment explained in the description are envisaged. The scope of the invention is only limited by the scope of the claims.
