ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a power distribution outlet and, more particularly, the present invention relates to a power distribution outlet allowing a multiplicity of electronic products to be systematically connected to a car battery. The power distribution outlet has an easily assembled/dissembled fuse providing the convenience and safety for the application of the electronic products.
The typical car is equipped with a variety of power-consuming electronic products, such as the generator, lamp, car stereo and air conditioning system. However, the amount of car batteries providing electricity to the electronic products is limited. When the number of the electronic products is larger than the amount of the car batteries, the electric wiring layout of the power-consuming electric products becomes very crucial. As the new models of cars are continuously developed, in addition to the improvement of performance and safety, comfort level, convenience and added values are also emphasized. Therefore, cars are often promoted with some advanced equipments such as the expensive electronic equipment (for example, the ABS anti-lock breaking system, GPS navigation system and etc.), or high-end video and audio system. Consequently, the amount of required electric wires is increased. However, in the traditional design, the wires are directly connected to the electrode of the car battery via respective ring clips formed on the ends thereof. This causes the inconvenience for individually connecting and disconnecting. Further, the overlapping connection of the electric wires causes great danger. Therefore, the industry has developed some special battery distribution outlet to overcome the problem.
Referring to
FIGS. 1 and 2
, a conventional power distribution outlet
8
is illustrated. The power distribution outlet
8
comprises a connector body
80
and a connection socket
85
. The connector body
80
comprises a clamp portion
81
, a wire inlet
82
and a slot
83
. The clamp portion
81
includes a bolt
810
for firmly connecting the electrode of a car battery (not shown). More than one wire inlets
82
may be formed to accommodate filaments
90
of power cords
9
. The filaments
90
are fixed by the pressing screws
820
. The slot
83
is in the shape of a dovetail. The connection socket
85
includes an insulator block
86
and mutually insulated first and second conductor blocks
87
and
88
enclosed in the insulator block
86
. The first conductor block
87
comprises a board
870
extending from the insulator
86
. The board
870
has a shape matching the dovetail shape of the slot
83
, such that the connector body
80
is conducted to the connection socket
85
by engaging the board
870
with the slot
83
. Another wire inlet
880
is formed on the second conductor block
88
. More than one wire inlets
880
can be formed according to specific requirement for accommodating the filaments
90
of another power cords
9
. The power cord
9
is firmly attached by pressing the screw
881
towards the filaments
90
. The first and second conductor blocks
87
and
88
further comprise electrode portions
871
,
882
, respectively, allowing the fuse
89
to be inserted. Thereby, many electric wires can be conducted via the power distribution outlet
8
to deliver electricity, and the electronic products connected by the electric wires are protected by the fuse
89
.
However, in the above power distribution outlet
8
, the connector body
80
and the connection socket
85
are connected by snapping the board
870
with the slot
83
, while the slot
83
and the board
870
are in dovetail shape. The fabrication precision is highly demanded to cause great process difficulty.
According to the above, the conventional power distribution outlet still has inconvenience and drawbacks to be improved.
Therefore, the Applicant has performed researches and tests to develop a design based on the relative theory and years of working experience in this field to improve the inconvenience and drawback of the conventional design.
BRIEF SUMMARY OF THE INVENTION
The present invention provides a power distribution outlet in which a fuse can be easily installed and multiple power cords to be plugged tidily and stably connected to the battery. The power distribution outlet provided visibly inspected fuse could be easily replaced to protect the electronic products. Further, the power distribution outlet is easily for production.
The power distribution outlet provided by the present invention comprises a connector body, a distributing block, an insulation plate, a fuse and an insulation housing. The connector body includes a clip portion, a joining surface, a first electrode portion and a plurality of wire inlets. The clip portion is clamped with the electrode of the battery. The distributing block is a conductor matching to the engaging portion, and has a second electrode portion disposed aligned with and a plurality of wire inlets for receiving power cords. The insulation plate is to fix the connector body and the distributing block into an insulated and single body thereon. The fuse has two conducting parts connected to the first and second electrode portions, respectively. The connector body and distribution block are electrically conducted to each other thereby. The connector body and distribution block are then enclosed by the insulation housing.
