## Abstract

An electrical wire connection device includes a housing having a top surface and opposite end surfaces that respectively intersect the top surface at end edges of the top surface. Each end edge forms a cutoff. A cover board is openably closed to the top surface of the housing to expose an opening of the cutoff in the respective end surface. The opening allows the insertion of a tip of a hand tool, such as flat-ended screwdriver, to pry the cover board open. In this way, the cover board can be opened easily and efficiently without damage to the housing or the cover board.

## Claims

### Claim 1

An electrical wire connection device comprising:
a housing made of insulation material and forming first and second channels for receiving therein first and second electrical wires, a cover board extending from a bottom of the housing and having a remote free edge forming a barb, the housing having a top surface in which a recess extending between the first and second channels is defined, the top surface of the housing having an outer side edge forming an engaging section engageable with the barb of the cover board; and
an interconnection member made of electrically conductive materials and forming at least one blade in which two notches are defined;
wherein the housing has an outer side surface forming a rib below the engaging section, and the housing has opposite end surfaces respectively intersecting the top surface of the housing at end edges, each end edge forming a cutoff so that when the cover board is closed to the top surface of the housing, the cutoff shows an opening in the respective end surface of the housing.

### Claim 2 (depends on 1)

The electrical wire connection device as claimed in claim 1, wherein the rib is integrally formed with a protrusion that extends from the bottom of the housing to the outer side surface of the housing.

### Claim 3 (depends on 1)

The electrical wire connection device as claimed in claim 1, wherein the rib extends a length smaller than a length of the cover board.

### Claim 4 (depends on 2)

The electrical wire connection device as claimed in claim 2, wherein the rib extends a length smaller than a length of the cover board.
