Problems solved by technology

However, the disadvantage is that stamping of the locking bracket produces stamped edges which can damage the locking projections on the second housing part during locking
[0006] If the locking protrusion is made of plastic or a relatively soft material such as aluminum, then when the locking bracket is turned to the closed position, it will cause the surface of the locking protrusion to wear, which may eventually break the locking protrusion
Even if the locking protrusion is made of harder metal, when the locking bracket is turned to the closed position, it will cause friction between the two metal parts, that is, the friction between the locking protrusion and the locking arm, so that the two The surface of the metal part is damaged, which can cause corrosion more quickly

Embodiment Construction

[0027] figure 1 and figure 2 An electrical plug connector 1 is shown which has a housing base as the first housing part 2 and a housing cover as the second housing part 3 . In the two housing parts 2, 3, a plurality of terminals interconnected with terminal boards or contact plugs can be arranged respectively for connecting a single core wire of a cable, but since the present invention relates to two housing parts 2, 3 locking devices, so these terminals are not shown in the drawings.

[0028] In the illustrated exemplary embodiment, two identical locking brackets 4 that are pivotably secured to the first housing part 2 are provided for the mutual fixing and / or locking of the two housing parts 2 , 3 . In this case, two bearing pins 5 are respectively provided for supporting the locking bracket 4, so that, in the illustrated embodiment, the first housing part 2 has a total of four bearing pins (main journals) 5, which form They are arranged opposite to each other on two lon...

Abstract

The invention relates to an electrical plug-in connector and interlocking clip for interlocking of two housing parts. The electrical plug-in connector with a first housing part, a second housing part and at least one metal interlocking clip which is pivotally mounted on the first housing part, two bearing journals being mounted on the first housing part and two interlocking projections being provided on the second housing part, the interlocking clip having two interlocking legs and a handle piece which connects the interlocking legs to one another, the interlocking legs each having a bearing arm with a recess for the bearing journal and an interlocking arm for overlapping an interlocking projection. Damage to the interlocking projections by the metal interlocking arms is prevented by two plastic parts which are located on the two interlocking legs of an interlocking clip such that a respective section of a plastic part covers the free end surface of an interlocking arm when the interlocking clip is pivoted into the closed position.

Description

technical field [0001] The invention relates to an electrical connector having a first housing part, a second housing part and at least one metal locking bracket pivotably mounted on one of the two housing parts, Wherein two support pins are set on the first housing part, two locking protrusions are set on the second housing part, the locking frame has two locking legs and a handle which connects the locking legs to each other, and the locking The legs each have a support arm and a locking arm for engaging the locking projection, wherein the support arms have recesses for the support pins. In addition, the invention also relates to a locking bracket for locking two housing parts, in particular two housing parts of an electrical plug connector, which has two locking legs and a locking leg which connects the locking legs to each other. Attached handle. Background technique [0002] Such electrical plug connectors have been used in particular in the industrial sector for many...
