Abstract

An electrical connector in which preselected terminals (16) are shunted. Contact portions (108) of the terminals (16) are aligned with a shunt bar (113, 113 min ) and are resiliently deformable from positions engaging the shunt bar (113, 113 min ) in an unmated condition of the connector to positions spaced from the shunt bar (113, 113 min ) in a mated condition of the connector by mating engagement with a complimentary connector. The shunt bar (113, 113 min ) comprises a bridge portion from which asymmetrically spaced contact lugs (116, 117, 116 min , 117 min ) depend. Two shunt bars (113, 113 min ) are located in tandem in back-to-back relation in a housing (15) so that alternate contact tongues (108) are aligned with respective contact lugs (116, 117 min , 116 min , 117) on respective shunt bars (113, 113 min ).

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to electrical connectors, and more particularly to electrical connectors for use in the data communications industry.

These open data links are designed to prevent redundant and potentially erroneous electrical signals from being transmitted along the link line to the device due to poor connections or electrical strays. The line needs to protect the equipment it extends from.

Therefore, a method of diverting the scheduled terminals of the interface has been proposed. According to the conventional methods proposed, in order to realize a data link by combining connectors, there is a drawback that the flow dividing mechanism must be manually removed before combining the connectors.

U.S. Patent No. 4. ．． No. 224,486 discloses an insulating housing having a front mating surface, a rear wire connection surface, a wire connection portion disposed on the wire connection surface and a contact portion disposed on the combination surface within the housing. An electrical connector is shown containing a plurality of attached terminals and an electrical shunt device mounted within the housing in alignment with the contact portions.

According to this connector, when the connectors are connected, the flow dividing device can be disengaged without any trouble due to the coupling action. must be provided. This requires additional space in the connector assembly and increases construction complexity, cost, and size.

According to the invention, the contact portion is spaced apart from the flow diverter from a position in which it engages the flow diverter when the connectors are not mated, and in order to engage the contact portion of a complementary connector when the connectors are mated. It is arranged so that it can be elastically deformed in this direction.

Therefore, there is no need to manipulate the flow divider in any way before assembling the connectors, and there is no need to complicate the overall assembly.

Preferably, the flow diverter comprises an integrally formed separation bar with a bridging portion extending laterally with respect to the contact portion formed as a tongue, and contact lugs spaced apart from each other by a distance of 1. Each contact tongue ζ extends laterally with respect to the bridge portion and is formed to engage with the contact tongue ζ when the connector is not assembled.

Therefore, only the terminals that are scheduled to be spaced apart need to be shunted, and the intermediate terminals are bridged.

More specifically, the contact lugs are asymmetrically located along the bridge section and are juxtaposed with additional separation rods similar to the first separation rod, transposed 180 degrees with respect to the first separation rod. With such a construction, the contact lugs will be aligned alternately with the contact lugs of each separation bar.

The separating rod can be formed with an identification device so that when the separating rod is received in the housing, the separating rod is only received in a predetermined position direction.

The contact tongue is preferably folded back so that its rearwardly extending free end is aligned with each contact lug.

Since the tongue pivots around the fold line during mating and engagement of the connectors, the advantage is that the degree to which the free end is separated from the contact lug of the flow diverter rod is greater than the degree of displacement of the contact portion. It will be done.

Embodiments of the connector according to the present invention will be described below with reference to the drawings.
