It is desired that a shielded sealed header connector assembly, which comprises a header housing, a metal shield member, inserted therein, and an inner housing. The header housing is comprised of an outer shell having an upper shell body and a base member. The outer shell is mounted onto a metal case when in operational use with the inner housing. The header housing is mounted and locked with the inner housing which is inserted into the header housing. The inner housing, may hold at least one metal contact or pin spaced apart at specific spacings. The inner housing and/or the header housing, may be connected to an electrical component (such as, a main body containing terminals, a power assembly, a high voltage and interlock loop (HVIL) assembly, or the like), which may in turn be connected or attached to an electrically emitting device.
In order to aid in the protection of the inner housing from external damage, when in use, the header housing, encapsulates and/or surrounds a portion of the inner housing which extends above the metal case and into the outer shell; protecting the inner housing from external damage either due to external physical impact, external environmental contaminants, or other adverse external harms that affect the satisfactory performance and/or usability of the header connector assembly. Additionally, the metal shield member shields the inner housing from EMI (electric or magnetic field interference), electrical emission or generation forces, as well as other electromagnetic spectrum or the like. The metal shield also has tabs which contact the metal case, for grounding purposes, aiding in the performance or effect of the shield member, and may also be part of a grounding scheme if required.
Further, the header housing is fixed or secured to the metal case with bolts, providing solid fixation and contact of the base member of the outer shell to the metal case. The fixation or securing of the header housing to the metal case, secures the outer shell to the metal case, and allows for the protection and sealing of the inner housing as well.
Additionally, during, for example, transport or some other occasion, if the outer shell becomes damaged due to adverse effects, for example, physical impact, or becomes generally unusable, for example, unable to protect the inner housing (unable to seal, or shield), it is essential that the header housing, outer shell with metal shield member, be serviced or replaced to restore the satisfactory performance and/or usability of the header housing in the header connector assembly.
When it becomes necessary for the header housing, outer shell containing the shield member, to be serviced or replaced due to physical damage or due to its inability to protect (i.e., by shielding or sealing) the inner housing, it is important and essential that the header housing, be readily and efficiently unlocked, disaseembled, detached, or removed from the inner housing. That is, it is important that a method be made available to unlock, disassemble, detach, or remove a damaged or unusable header housing, from the inner housing, and that such unlocking, detaching, disassembling, or removing of the the header housing from the inner housing be readily, easily and efficiently made. That is, it is important that the damaged or unusable header housing be detached from the metal case, and readily and efficiently unlocked, disassembled, detached or removed from the inner housing, and to be serviced or replaced by a user.
When a header housing is unsecured from the metal case and, unlocked, disassembled, detached, or removed from the inner housing, for service or repair by a user, it is also important that the inner housing remains connected to its associated or corresponding electrical component and remains inserted into an aperture of the metal case.
It is similarly important that, once the header housing is unlocked, disassembled, detached, or removed for replacement or service, a method be made available for reassembly with a repaired header housing (containing a shield member) or a new header housing (containing a new shield member) to be readily and efficiently secured, attached, assembled, or mounted onto the metal case with installation of the bolts, as well as locked, attached, and assembled with the inner housing.
When a repaired or replaced header housing, is locked, attached and assembled with the inner housing, it is also important that the inner housing remains connected to its associated or corresponding electrical component and remains inserted into the aperture of the metal case.
This invention is directed to a shielded sealed “header” connector assembly, which comprises a header connector, a metal shield member, inserted therein, and an inner housing, and method for disassembling or assembling thereof. The header connector of this invention is preferably comprised of an outer shell having the metal shield member inserted therein. The outer shell of the header housing protects the inner housing that is connected to an electrical device (such as, a main body containing terminals, a power assembly, a high voltage and interlock loop (HVIL) assembly, or the like). The header housing is mounted onto the metal case with bolts, and locked with the inner housing. The inner housing of this invention, may hold at least one metal contact or pin spaced apart at specific spacings, and may also have have terminals and bus bars attached. The inner housing preferably remains connected to an associated or corresponding electrical device. The header housing of this invention, which is comprised of the outer shell with the metal shield member, shields or seals the inner housing from external damage, either due to physical impact or from environmental contaminants. The metal shield member, also protects the inner housing from EMI (electric or magnetic field interference), electrical emission or generation forces, as well as other electromagnetic spectrum or the like. The metal shield member also has tabs which contact the metal case for grounding purposes and for shielding performance. During, for example, transport or some other occasion, the detachable header housing, in this invention, may become damaged or unable to, generally, protect the inner housing. The detachable header housing, containing the outer shell with the shield member, of this invention is required to be readily serviced or replaced. That is, in this invention, when a user finds it or it becomes necessary for the header housing, the outer shell with the shield member, to be serviced or replaced due to physical damage or due to the inability to protect (i.e., by shielding or sealing) the inner housing, of this invention is readily and efficiently detached, disassembled, or removed from the metal case and unlocked from the inner housing. This invention is further directed to a method to unlock, detach, disassemble, or remove a damaged header housing, from the inner housing. The header housing and inner housing each having a latch member which disengages from the other, unlocking the header housing. Such method of this invention of detaching, disassembling, or removing of the damaged header housing of the header connector assembly is easily and efficiently made. That is, the header housing of this invention, when damaged or unusable, is readily and efficiently detached, disassembled, or removed from the metal case and unlocked from the inner housing, and to be serviced or replaced by a user, for example, by using a screwdriver or tool.
Furthermore, in this invention, when the header housing of this invention is detached, disassembled, or removed from the inner housing, for service or repair, the inner housing remains connected to its associated or corresponding electrical device and within an aperture of the metal case.
