Apparatus for line assembly of high tension connectors with pivot pins

Abstract

The present invention relates to a device for the production-line assembly of a connector comprising at least two pivoting contact pins, each pin comprising a terminal the end of which is flattened and pierced with a hole accommodating a tapped insert able to accept a clamping screw, each tapped insert forming a shoulder on said flattened end. The device comprises a flat base made of electrically insulating material supporting means of attachment to each pin, these means being arranged in such a way that the flattened end of the terminal of said pin bears against the flat base to prevent said pin from rotating, the ends of the clamping screws and the shoulders formed by the tapped inserts being accommodated in the orifices pierced in the flat base. The device also comprises at least one partition made of electrically insulating material and positioned in such a way that the pins cannot be brought into contact via the clamping screw or by a tool for tightening said screw when the flattened ends of the terminals thereof bear against the flat base. The partition comprises means for limiting the height of the stack of contactors to a predetermined height.

Description

technical field [0001] The present invention relates to the field of connectors for high tension applications. It is particularly, though not exclusively, applicable to traction battery packs of motor vehicles. Background technique [0002] Note that high current, high voltage (eg 250 amps, 400 watts) applications require the use of specialized connectors that provide a high quality level of contact, especially in terms of contact area. Therefore, in order to maximize the contact area, commercially available connectors include pivot pins with flat ends that incorporate threaded holes so that these clamp connection interface planes fit nearly perfectly. An example of such a prior art connector will be described in detail in the remainder of this application. [0003] A disadvantage of this connector is that its pins can pivot, which is undesirable during transport or during handling by operators on the production line, with the result that it is impossible to assemble the c...

Problems solved by technology

[0003] A disadvantage of this connector is that its pins can pivot, which is undesirable during transport or during handling by operators on the production line, with the result that it is impossible to assemble the connector on the production line, at least Resulting in reduced production line efficiency, possible rework, and even rejects

Another disadvantage of this type of connector is that its pins are very close to each other, and a dropped tool or clamping screw can bring the two pins into contact and cause a short circuit, causing damage to the connector and exposing the operator to hazards

Another disadvantage of such connectors is the risk of an unsafe connection, especially when they have to be connected with tabs, as explained in more detail below
