Abstract
Abstract An electrical connector capable of being used in a process for insulating a wire joint, includes a plastic plug having a tubular insert section and a plastic casing with an open end sized to receive the tubular insert section and a closed end defining a plurality of ports. A plurality of electrical wires are insulated by plastic tubes that extend through corresponding ports to define a series of passages. Plastic bonding agent is captivated within a space defined by the plug and casing to encapsulate bared electrical wire ends held together a a joint inside the casing. Another portion of the plastic bonding agent is extruded entirely throughout the annular passages in order to bond the casing and plastic tubes together.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
148 words
An electrical connection comprising: a. a plastic casing having a sidewall, an open end and a closed end with plural ports therethrough, the casing closed end thickness being at least twice as thick as the casing sidewall thickness; b. a plastic plug having a tubular insert section fitting snugly within the casing and engaging the casing closed end, and, having an enlarged cap engaging the casing open end; c. a plurality of plastic insulated electrical wires extending through said ports that are larger than the plastic insulated electrical wires to define therewith plural annular passages, the electrical wires having inner ends joined together inside the casing; and, d. a bonding agent captivated within and totally occupying the space defined by the plug and casing encapsulating the wire joint, the bonding agent being extruded entirely through the annular passages and bonding the casing and plastic insulated electrical wires together.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
22 words
The structure according to claim 1 wherein: the ports are perpendicular to the casing closed end and parallel to the casing axis.
Claim 4
Dependent Claim
45 words
The structure according to claim 1, wherein; the plastic casing and plug are constructed from rigid polyvinyl chloride, the plastic of the plastic insulated electrical wires is plasticized polyvinyl chloride and the bonding agent is a suitable thermoplastic polymer adhesive composition compatible with polyvinyl chloride.
Claim 5
Dependent Claim
21 words
The structure according to claim 1, wherein; the electrical wires are joined together by a sleeve crimped over their inner ends.
Claim 6
Dependent Claim
44 words
The structure according to claim 1, wherein; the end of the tubular insert section which engages the casing closed end is tapered towards its edge from inside to outside to constitute a guide for facilitating movement of the wires into the tubular insert section.
