Abstract
Abstract A waterproof splice connector for pairs of electrical leads having a high tensile pullout resistance, suitable for use in splicing blasting cap leads, in which the each of the electrical leads are received in opposite ends of a respective one of a pair of clip connected tubular bodies, through holes formed in sealing end plugs. A tubular metal insert is disposed in each body and has oppositely directed roughly conical lead end receptacles, each formed with wire lead retaining barbs. The conical receptacles overlap such that the full length of the insert is utilized to grip a respective electrical lead. The sealing plugs are formed of a resilient material compressed into converging transition sections of the connector body to compress the plug ends and thereby close off the openings and sealingly grip a respective electrical lead. The interior of the connector is filled with an anti-oxidant sealant enhancing the water proofing of the connector interior.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
98 words
A splice connector for electrical leads comprising: a tubular body of an electrically insulating material; a sealing plug of a resilient, electrically insulating material mounted in each end of said tubular body having a central opening to receive an electrical lead; a tubular insert mounted within said tubular body so as to receive electrical leads inserted through either end plug; convergent oppositely directed conductive electrical lead receptacles and overlapping each other in said insert for receiving a respective electrical lead; a plurality of barbs extending inwardly from said receptacle walls to grip and retain electrical leads inserted therein.
Claim 2
Dependent Claim
98 words
A splice connector for electrical leads comprising: a tubular body of an electrically insulating material; a sealing plug of a resilient, electrically insulating material mounted in each end of said tubular body having a central opening to receive an electrical lead; a tubular insert mounted within said tubular body so as to receive electrical leads inserted through either end plug; convergent oppositely directed conductive electrical lead receptacles and overlapping each other in said insert for receiving a respective electrical lead; a plurality of barbs extending inwardly from said receptacle walls to grip and retain electrical leads inserted therein.
Claim 3
Dependent Claim
26 words
The splice connector according to claim 1 wherein said receptacles are mounted extending within said insert to be inclined across the width of said tubular insert.
Claim 4
Dependent Claim
27 words
The splice connector according to claim 1 wherein said tubular insert is formed of crimpable metal to enable crimping thereof at each end through said tubular body.
Claim 5
Dependent Claim
23 words
The splice connector according to claim 1 wherein said tubular body is of transparent plastic allowing visual inspection of an inserted electrical lead.
Claim 6
Dependent Claim
35 words
The splice connector according to claim 1 further including a clip able to be snap fit to a pair of tubular bodies of side-by-side connectors to enable securement together of a pair of splice connectors.
Claim 7
Dependent Claim
77 words
The splice connector according to claim 1 wherein said tubular body is formed with a transition section between a middle section and each of a larger diameter expanded end, each end receiving a respective sealing plug, and wherein each sealing plug is press fit thereinto and compressed into said transition section, said central opening and transition section sized so that insertion of said sealing plug closes off said central opening at one end of said sealing plug.
Claim 8
Dependent Claim
28 words
The splice connector according to claim 6 wherein the interior of said middle section of said tubular body and said tubular insert is filled with an anti-oxidant sealant.
Claim 9
Dependent Claim
13 words
The splice connector according to claim 7 wherein said sealant is silicon grease.
