Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
241 words
A connector comprising: an insulating substrate having a substantially rectangular parallelepiped shape, a plurality of strip-shaped contacts arranged substantially in parallel to one another at regular intervals, said contacts being molded integrally with said insulating substrate so as to extend through said substrate in a direction perpendicular to the lengthwise direction of said substrate with the opposing ends of said contacts projecting outwardly of said substrate, each said contact defining a terminal portion at one of its outwardly projecting ends, a contact portion at the other of its outwardly projecting ends, and a contact holding portion which is located between said ends and embedded within said insulating substrate, each of said contact portions being bent back towards its corresponding contact holding portion to lie on one surface of said insulating substrate, the surface of said insulating substrate having contact receiving grooves therein which extend in the widthwise direction of said substrate and which are arranged along the lengthwise direction of said substrate for receiving said bent back contact portions, an elongated metal reinforcing plate embedded within said insulating substrate, said reinforcing plate extending in the lengthwise direction of said substrate and being disposed adjacent to, spaced from, and in opposing relation to said contact holding portions, and insulating layer means disposed between said reinforcing metal plate and each of said contact holding portions, said insulating layer means being made of an insulating material different from the material of said insulating substrate.
Claim 2
Dependent Claim
241 words
A connector comprising: an insulating substrate having a substantially rectangular parallelepiped shape, a plurality of strip-shaped contacts arranged substantially in parallel to one another at regular intervals, said contacts being molded integrally with said insulating substrate so as to extend through said substrate in a direction perpendicular to the lengthwise direction of said substrate with the opposing ends of said contacts projecting outwardly of said substrate, each said contact defining a terminal portion at one of its outwardly projecting ends, a contact portion at the other of its outwardly projecting ends, and a contact holding portion which is located between said ends and embedded within said insulating substrate, each of said contact portions being bent back towards its corresponding contact holding portion to lie on one surface of said insulating substrate, the surface of said insulating substrate having contact receiving grooves therein which extend in the widthwise direction of said substrate and which are arranged along the lengthwise direction of said substrate for receiving said bent back contact portions, an elongated metal reinforcing plate embedded within said insulating substrate, said reinforcing plate extending in the lengthwise direction of said substrate and being disposed adjacent to, spaced from, and in opposing relation to said contact holding portions, and insulating layer means disposed between said reinforcing metal plate and each of said contact holding portions, said insulating layer means being made of an insulating material different from the material of said insulating substrate.
Claim 3
Dependent Claim
40 words
A connector according to claim 1 including a terminal formed integrally with the metal reinforcing plate and extending outwardly from the insulating substrate for electrical connection to an electrostatic capacitance between the metal reinforcing plate and each contact holding portion.
Claim 4
Dependent Claim
44 words
A connector according to claim 1 which further includes a cover detachably mounted on the insulating substrate in facing relation to the contact receiving grooves for pressing terminal pins, that have been inserted into the contact receiving grooves, against said bent back contact portions.
Claim 5
Dependent Claim
109 words
A connector according to claim 3, wherein the cover is provided with a slider and a holding plate slidable relative to each other in the lengthwise direction of the insulating substrate, said cover including means for biasing the slider and the holding plate in a fixed one of the directions of their sliding movement, and said cover further including engaging means operative, when the cover is pressed against the insulating substrate with the holding plate held on a side thereof, to cause the slider to slide against the biasing force of the biasing means and then to be returned by the biasing force into engagement with the insulating substrate.
Claim 6
Dependent Claim
59 words
A connector according to claim 1, wherein a second insulating substrate is assembled with the insulating substrate on the side of its contact receiving grooves to define therebetween an opening communicating with the contact receiving grooves, for receiving a mating connector inserted into said opening from the side of the contact bent back portions of the contact receiving grooves.
Claim 7
Dependent Claim
23 words
A connector according to claim 5, wherein the second insulating substrate has embedded therein a reinforcing metal plate extending in its lengthwise direction.
Claim 8
Dependent Claim
77 words
A connector according to claim 6, wherein a plurality of second contacts are held by the second insulating substrate in side by side relation to one another in the lengthwise direction of said second substrate, said second contacts having contact holding portions which are embedded in the second insulating substrate and also having contact portions which are received in second contact receiving grooves formed in the second insulating substrate to communicate with said mating connector receiving opening.
Claim 9
Dependent Claim
61 words
A connector according to claim 1, wherein said reinforcing metal plate is disposed opposite to said contact holding portions on the side of said bent back contact portions, the marginal portion of said reinforcing metal plate on the opposite side from the bent back contact portions being bent substantially at right angles towards said contact portions to form a reinforcing rib.
Claim 10
Dependent Claim
25 words
A connector according to any one of claims 1 or 3 to 8, wherein the insulating layer means is a spacer of an insulating material.
Claim 11
Dependent Claim
33 words
A connector according to any one of claims 1 or 3 to 8, wherein the insulating layer means is a coating of an insulating material on the surface of the metal reinforcing plate.
Claim 12
Dependent Claim
31 words
A connector according to any one of claims 1 or 3 to 8, wherein the insulating layer means is a layer of oxidation on the surface of the metal reinforcing plate.
Claim 13
Dependent Claim
30 words
A connector according to any one of claims 1 or 3 to 8, wherein the insulating layer means is a coating of an insulating material on each contact holding portion.
Claim 14
Dependent Claim
34 words
A connector according to any one of claims 1 or 3 to 8, wherein the insulating layer means constitutes coatings of an insulating material on each contact holding portion and on the metal plate.
Claim 15
Dependent Claim
33 words
A connector according to any one of claims 1 or 3 to 8, wherein the insulating layer means is an insulating adhesive binder layer joining each contact holding portion to the metal plate.
Claim 16
Dependent Claim
32 words
A connector according to any one of claims 1 or 3 to 8, wherein the insulating layer means is a two-sided adhesive tape joining each contact holding portion to the metal plate.
