Abstract
Abstract In a relay according to this invention the terminal elements (17) are injection-molded into wall members (2,3) which are so designed that they during assembly, and if so required, together with parts of the flange (35) of the coil (16) of the electromagnetic driving system, form a cup-shaped member having a bottom part (4). The rim portion (9) of the cover member (1) which is capable of being placed thereon, projects over the bottom part (4). The thus resulting space may be filled with a sealing compound (casting resin) (13). From this there results a tight relay consisting of a few individual parts only, which is easy to manufacture and which, moreover, is solder- and wash-tight.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
119 words
Electromagnetic relay with terminal elements projecting therefrom and comprising: a cup-shaped cover slidably and frictionally engaging with a pair of juxtaposed shells being self-aligned and self-locked relative to each other; each shell having a plurality of said terminal elements being integral therewith and depending from one wall thereof; said shells housing and complementary engaging an electromagnetic drive system so as to form continuous common bottom and side walls therewith; terminal elements depending from both said system and said shells and projected outwardly from said common bottom wall; said common bottom wall being offset from a rim of said cover; a waterproof sealing compound filling the space in said offset and sealing all joints and seams of said bottom wall.
Claim 2
Dependent Claim
119 words
Electromagnetic relay with terminal elements projecting therefrom and comprising: a cup-shaped cover slidably and frictionally engaging with a pair of juxtaposed shells being self-aligned and self-locked relative to each other; each shell having a plurality of said terminal elements being integral therewith and depending from one wall thereof; said shells housing and complementary engaging an electromagnetic drive system so as to form continuous common bottom and side walls therewith; terminal elements depending from both said system and said shells and projected outwardly from said common bottom wall; said common bottom wall being offset from a rim of said cover; a waterproof sealing compound filling the space in said offset and sealing all joints and seams of said bottom wall.
Claim 3
Dependent Claim
25 words
A relay as claimed in claim 1, and said drive system including a flange element abutting said shells so as to form said continuous walls.
Claim 4
Dependent Claim
23 words
A relay as claimed in claim 1, and said bottom wall having a T-shaped seam formed by said shells and said drive system.
Claim 5
Dependent Claim
27 words
A relay as claimed in claim 1, and said shells being self-aligning and self-locking by utilizing pins projecting from one shell into matching recesses in another shell.
Claim 6
Dependent Claim
31 words
A relay as claimed in claim 1, and said one wall of each shell being a side wall perforated by a plurality of openings facilitating an access to said terminal elements.
Claim 7
Dependent Claim
39 words
A relay as claimed in claim 1, and said drive system comprising a flange member abutting said shells and including parts matching corresponding counterparts in said shells; said flange member being located at one end of said drive system.
Claim 8
Dependent Claim
14 words
A relay as claimed in claim 6, and said flange having a U-shaped configuration.
Claim 9
Dependent Claim
19 words
A relay as claimed in claim 1, and said shells comprising coupling means for securing said flange member thereto.
Claim 10
Dependent Claim
20 words
A relay as claimed in claim 1, and said shells comprising ribs supporting a coil means of said drive system.
Claim 11
Dependent Claim
23 words
A relay as claimed in claim 1, and said shells having locating means accommodating recesses and protrusions of elements of said drive system.
Claim 12
Dependent Claim
178 words
An electromagnetic relay structure comprising: a cup-shaped cover slidably and frictionally engaging with a pair of juxtaposed shells being self-aligned and self-locked relative to each other; each shell having a plurality of said terminal elements being integral therewith and depending from one wall thereof; said shells housing and complementary engaging an electromagnetic drive system so as to form continuous common bottom and side walls therewith; terminal elements depending from both said system and said shells and projected outwardly from said common bottom wall; said common bottom wall being offset from a rim of said cover; a sealing compound filling said offset space so as to provide a waterproof sealing layer inside said cover; said drive system including a flange element abutting said shells so as to form said continuous walls; said one wall of each shell being a side wall perforated by a plurality of openings facilitating an access to said terminal elements; said shells comprising coupling means for securing said flange member thereto; said flange supporting and rigidly attached to a coil body of said drive system.
