The present invention is directed a terminal blade which accepts different types of mating connectors. In particular, the invention is directed to a terminal blade in which the tab portion includes insulation displacement slots.
Electrical current may be delivered to a device through various methods. For example, the device may have a connector in which tabs of electrical contacts mate with receptacles of mating contacts of a mating connector to allow the electrical current to be supplied to the device. Alternatively, the device may have insulation displacement contacts which pierce the insulation of electrical conductors to supply the current to the device.
While the various methods of supply the current to the device are effective, the method and configuration of the mating connector which supply the current are limited by the configuration of the electrical contacts of the device. Consequently, adaptors and the like may be required in order to properly supply current to the device. This can increase the cost and reduce the efficiency of providing current to the device.
It would, therefore, be beneficial to provide electrical contacts of the device with terminal blades which accept different types of mating connectors or conductors. In particular, it would be beneficial to provide terminal blades in which the tab portions include insulation displacement slots, thereby allowing the electrical contacts to be electrically connected to mating plug assembly or mating conductors without the need of providing adaptors or the like.
An embodiment is directed to an electrical contact having a contact base and a tab section. The tab section extends from the contact base. The tab section has a first wall and an oppositely facing second wall. The first wall and the second wall are configured to make an electrical and mechanical connection to a mating receptacle portion of a mating contact of a first mating plug assembly. An insulation displacement slot is provided in the tab section. The insulation displacement slot extends from the end surface. The insulation displacement slot is configured to make an electrical and mechanical connection to electrical conductors of a second mating assembly.
An embodiment is directed to a lead frame having a housing and a plurality of contacts. The housing has a mating connector receiving recess. Individual contacts of the plurality of contacts have a contact base and a tab section. The tab section extends from the contact base. The tab section has a first wall and an oppositely facing second. The first wall and the second wall are configured to make an electrical and mechanical connection to a mating receptacle portion of a mating contact of a first mating plug assembly. An insulation displacement slot is provided in the tab section. The insulation displacement slot extends from the end surface. The insulation displacement slot is configured to make an electrical and mechanical connection to electrical conductors of a second mating assembly.
An embodiment is directed to a lead frame having a housing with a mating connector receiving recess. A first latching projection is provided on a front wall of the housing and is provided proximate the mating connector receiving recess. A second latching projection extends from the housing proximate the mating connector receiving recess. A hinge projection extends from the housing proximate a back wall of the housing. A plurality of contacts are provided in the housing. Individual contacts of the plurality of contacts have a contact base and a tab section. The tab section extends from the contact base. The tab section has a first wall and an oppositely facing second wall. The first wall and the second wall are configured to make an electrical and mechanical connection to a mating receptacle portion of a mating contact of a first mating plug assembly. An insulation displacement slot is provided in the tab section. The insulation displacement slot extends from the end surface. The insulation displacement slot is configured to make an electrical and mechanical connection to electrical conductors of a second mating assembly.

An illustrative electrical connector or lead frame assembly 10 is shown in
The mating connector receiving recess 22 has contact receiving openings 24 which extend through a bottom surface 26 of the mating connector receiving recess 22. A portion of the front wall 16 forms a front wall 28 of the mating connector receiving recess 22. The mating connector receiving recess 22 has a back wall 30 which is spaced from the front wall 28.
Mounting openings 32 are provided on either side of the mating connector receiving recess 22. The mounting openings 32 extend from the second surface 14 toward the top surface 12.
A first latching projection 34 is provided on the front wall 16 and is provided proximate the mating connector receiving recess 22. The first latching projection 34 has a lead-in surface 36 and a latching shoulder 38.
Electrical contacts 52 are provided in the electrical connector 10. As shown in
The contacts 52a, 52b, 52c have tab sections 56a, 56b, 56c which extend from the respective contact bases 54a, 54b, 54c. In the illustrative embodiment shown, the tab sections 56a, 56b, 56c extend at approximately 90 degrees from the contact bases 54a, 54b, 54c. The tab sections 56a, 56b, 56c have first walls 58a, 58b, 58c and oppositely facing second walls 60a, 60b, 60c which extend from first side surfaces 62a, 62b, 62c, second side surfaces 64a, 64b, 64c and end surfaces 66a, 66b, 66c. The first side surfaces 62a, 62b, 62c and the second side surfaces 64a, 64b, 64c extend parallel to each other.
Insulation displacement slots 68a, 68b, 68c are provided in the tab sections 56a, 56b, 56c. The insulation displacement slots 68a, 68b, 68c extend from the end surfaces 66a, 66b, 66c.
Referring to
A cover 140 is provide on the mating connector 110. The cover 140 has second latching projections 142 which extend from the cover 140. The second latching projections 142 have lead-in surfaces 144 and latching shoulders 142.
Hinge projections 148 also extend from the cover 140. The hinge projections have hinge receiving slots 150 and hinge receiving openings 152.
Hinge projections 130 extend from side surfaces 132 of the mating connector 110 proximate a rear face 134 of the mating connector 110. Arcuate members 136 extend from the rear face 134 of the mating connector 110.
With the individual conductors 116 of the cable 114 properly positioned in the mating connector 110, the cover 140 is positioned on the mating connector 110. As this occurs, the hinge projections 130 of the mating connector 110 are inserted through the hinge receiving slots 150 and into hinge receiving openings 152 of the hinge projections 148 of the cover 140. The cover 140 is then pivoted or rotated relative to the mating connector 110. As this occurs, the second latching projections 142 cooperate with side surfaces 138 of the mating connector 110. The side surface 138 are moved past the latching shoulders 146 to retain the cover 140 on the mating connector 110.
With the cover 140 properly inserted onto the mating connector 110, the mating connector 110 is moved into engagement with to the connector 10. As this occurs, the arcuate members 136 are inserted into slots (not shown) provide in a housing into which the connector 10 is positioned. The mating connector 110 can be rotated from the open position shown in
In the mated position, the individual conductors 116 are positioned in the insulation displacement slots 68a, 68b, 68c, placing the individual conductors 116 in electrical and mechanical engagement with the contacts 52a, 52b, 52c.
Referring to
Latch 230 extends from a side surfaces 232 of the mating connector 210. The latch 230 has an opening 234 for receipt of the latch 40 therein. A locking shoulder 236 is provided proximate the opening 234
During assembly of the mating connector 210 to the connector 10, the mating face 212 of the mating connector 210 is inserted into the mating connector receiving recess 22. As this occurs, the mating contacts 214 are inserted onto the tab sections 56a, 56b, 56c of the contacts 52a, 52b, 52c.
As the mating connector 210 is moved to the mated position, the first latching projection 34 cooperates with the latch 230 of the mating connector 210. The locking shoulder 236 is moved past the latching shoulder 38 to retain the mating connector 210 in the mated position.
In the mated position, the mating contacts engage the first walls 58a, 58b, 58c and oppositely facing second walls 60a, 60b, 60c of the contacts 52a, 52b, 52c, thereby placing the mating contacts in electrical and mechanical contact with the contacts 52a, 52b, 52c of connector 10.
