Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
146 words
An electromagnetic relay including (a) a bobbin (2) carrying a coil (1) connected to a pair of coil terminals (6), the bobbin having an inner bore (23) along a longitudinal direction of the bobbin, (b) an armature (5) extending through said bore, (c) a pair of yokes (3) extending along said longitudinal direction and a permanent magnet (4) disposed between the pair of yokes for energizing said armature, (d) a movable contact (19) arranged laterally of said bobbin and having a first end connected to a first contact terminal (81) and a second end disposed for cooperation with at least one fixed contact (25) connected to a second contact terminal (82, 83), and (e) an actuating means (18) fixed to said armature and engaging said movable contact for driving the movable contact into and out of engagement with said fixed contact upon energization of said coil.
Claim 2
Dependent Claim
146 words
An electromagnetic relay including (a) a bobbin (2) carrying a coil (1) connected to a pair of coil terminals (6), the bobbin having an inner bore (23) along a longitudinal direction of the bobbin, (b) an armature (5) extending through said bore, (c) a pair of yokes (3) extending along said longitudinal direction and a permanent magnet (4) disposed between the pair of yokes for energizing said armature, (d) a movable contact (19) arranged laterally of said bobbin and having a first end connected to a first contact terminal (81) and a second end disposed for cooperation with at least one fixed contact (25) connected to a second contact terminal (82, 83), and (e) an actuating means (18) fixed to said armature and engaging said movable contact for driving the movable contact into and out of engagement with said fixed contact upon energization of said coil.
Claim 3
Dependent Claim
48 words
The relay of claim 1, wherein said coil terminals (6) and contact terminals (81 ... 83) are mounted on a base (7), said coil terminals being disposed at one side and said contact terminals at the other side of the bobbin (2) with respect to said longitudinal direction.
Claim 4
Dependent Claim
28 words
The relay of claim 2, wherein said base (7) has a recess shaped to receive said bobbin (2), yokes (3) and permanent magnet (4) in a press-fit manner.
Claim 5
Dependent Claim
71 words
The relay of any of claims 1 to 3, wherein said bobbin (2) has at one of its longitudinal ends projections (34) extending into said bore (23) to form a loose bearing for said armature (5), an end portion of said armature extending from said bore being provided with at least one lateral nose (33) cooperating with a respective one of said yokes (3) to form a fulcrum for said armature.
Claim 6
Dependent Claim
20 words
The relay of any of claims 1 to 4, wherein said yokes (3) are asymmetrical with respect to said armature.
Claim 7
Dependent Claim
52 words
The relay of any of claims 1 to 5, wherein said second end of said movable contact (19) is disposed between a pair of fixed contacts (25), said yokes (3) are symmetrical with respect to said armature (5), and said coil (1) is adapted to magnetize the armature in either longitudinal direction.
Claim 8
Dependent Claim
20 words
The relay of claim 6, wherein said coil (1) includes a middle tap connected to a third coil terminal (6).
Claim 9
Dependent Claim
35 words
The relay of any of claims 1 to 7, wherein said movable contact includes a contact spring (19) extending substantially parallel to said bobbin (2) and essentially over the entire length of said base (7).
Claim 10
Dependent Claim
48 words
The relay of any of claims 1 to 8, wherein said yokes (3) are generally U-shaped, including middle webs extending parallel to said armature (5) and legs extending from said middle webs and having end portions cooperating with end portions of said armature projection from said bore (23).
