Abstract
Abstract A distribution apparatus for telecommunication equipment wherein a contact component part is fastened on one side of a grounded bearing part and on the opposite side, a safety plug for the protection of electrical lines against voltage surges may be plugged in. The safety plug includes surge arresters resting with one pole against a grounding plate whose end is bent off laterally in the plug-in direction and is designed as grounding contacts which are acutely bent back on themselves and flexible, that substantially project beyond the safety plug. The grounding plate directly contacts the bearing part, thereby providing a maximum of transmitting reliability with a minimum of construction expenditure. The grounding contacts engage holes arranged within the range of an angled section of the bearing part.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
194 words
In a distribution apparatus for telecommunication equipment having a safety plug which plugs into a contact component part which is provided with terminal connecting components for incoming and outgoing electrical leads of telecommunications equipment, wherein the contact component part is held fast to at least one grounded bearing part, and wherein the safety plug has plug-in blades for corresponding opposite contacts of the contact component part connected to the terminal connecting components and a grounding contact which is connected to ground, the improvement comprising: said grounded bearing part having a bar-shape and being located at a lower surface of said contact component part to one side of said contacts of the contact component part; and said safety plug being plugged in a plug-in direction into said contact component part at an upper surface thereof opposite from the grounded bearing part, and said grounded contact of said safety plug being located to one side of said plug-in blades and shaped generally in the form of a finger projecting in the plug-in direction beyond the plug-in blades so that it makes contact with said grounded bearing part at the lower surface of said contact component part.
Claim 2
Dependent Claim

In a distribution apparatus for telecommunication equipment having a safety plug which plugs into a contact component part which is provided with terminal connecting components for incoming and outgoing electrical leads of telecommunications equipment, wherein the contact component part is held fast to at least one grounded bearing part, and wherein the safety plug has plug-in blades for corresponding opposite contacts of the contact component part connected to the terminal connecting components and a grounding contact which is connected to ground, the improvement comprising: said grounded bearing part having a bar-shape and being located at a lower surface of said contact component part to one side of said contacts of the contact component part; and said safety plug being plugged in a plug-in direction into said contact component part at an upper surface thereof opposite from the grounded bearing part, and said grounded contact of said safety plug being located to one side of said plug-in blades and shaped generally in the form of a finger projecting in the plug-in direction beyond the plug-in blades so that it makes contact with said grounded bearing part at the lower surface of said contact component part.
Claim 3
Dependent Claim
35 words
A distribution apparatus according to claim 1, wherein said contact component part includes a groove-shaped guiding channel for guiding said grounded contact of said safety plug in the plug-in direction to said grounded bearing part.
Claim 4
Dependent Claim
49 words
A distribution apparatus according to claim 2, wherein said safety plug includes a housing having a projection which covers a foot portion of said grounding contact where it extends from said housing, said projection being insertable with substantially no play into said guiding channel of said contact component part.
Claim 5
Dependent Claim
29 words
A distribution apparatus according to claim 3, wherein said projection and said guiding channel have corresponding edges which are slanted at an acute angle relative to the plug-in direction.
Claim 6
Dependent Claim
61 words
A distribution apparatus according to claim 1, provided with surge protection components coupled through said grounding contact for diverting voltage surges, wherein said finger of said grounding contact is formed with two spring legs, one of which rests in contact with a large surface and the other of which rests in contact with a smaller surface of said grounded bearing part.
Claim 7
Dependent Claim
114 words
A distribution apparatus according to claim 5, wherein said finger of said grounding contact is bent in a U-shape to form the two spring legs, and said grounded bearing part has an L-shaped cross section formed with one bearing leg extending in the plug-in direction, another bearing leg perpendicular to the plug-in direction, and an opening at the intersection of the two bearing legs, such that said finger of said grounding contact is insertable in said opening with one spring leg thereof resting flatly against and in contact with a large surface of said one bearing leg and the other spring leg rests against an edge of the other bearing leg adjacent said opening.
