FR2731116A1 - ELECTRICAL CONNECTOR HAVING THE LATCHING DEVICE HAVING AT LEAST ONE ELASTIC ELEMENT - Google Patents

Abstract

a) Electrical connector, the snap-fit device of which has at least one elastic element. b) Connector characterized in that the latching device consists of an element (13) as a locking element and at least one latching element (18) on the strut (12) as a counter element -locking, the element (13) covering at least part of the plug (11) and having at least one slot (14), which extends over part of the periphery of the element (13) and the surface of the cross section of the element (13) which serves to lock or separate the connection by exerting pressure on at least one actuating surface (16) which can be resiliently changed.

Description

"Electrical connector with a latching device at

less an elastic element "

State of the art

  The invention relates to an electrical connector with a plug and a strut that can be coupled to the first, this plug and this strut when they

  are attached which can be snapped together and separated again.

  by means of a snap-in device which presents

at least one elastic element.

  In the case of electrical connectors,

  which consist of a plug and a strut

  being able to be coupled to the first, elements of ver-

  rusting parts, which can be joined to a latching element serving as an element of

  counter-lock, to prevent inadvertent separation

  shut up parts. These locking elements are usually

  in the form of elastic elements

  such as springs, hooks or the like on the

  che, which latch when closing the con-

  rearward connection of the snap elements on the

  strut. When this connection is subject to

  high mechanical quotations in the case of a connection to

  of a motor vehicle, it is necessary to ensure

  Lock out the necessary elements

  in a reinforced way so as to avoid a separation

  connection under the effect of mechanical stresses

  considerable problems experienced by the connection during the

  of the motor vehicle. If the locking element is constituted in this case as a hook placed laterally on the plug, then it is necessary to give the large plug because of the lateral distance of the snap hook enlarged and reinforced which makes it more difficult to insertion of the connection in case one

  has narrowed seat conditions.

Advantages of the invention

  The connector according to the invention is characterized in that the detent device consists of an element as a locking element and at least one detent element on the strut as part of

  against-locking, the element overlapping at least in part

  the plug and having at least one slot, which extends over a portion of the periphery of the element and the surface of the cross section of the element which serves to lock or separate the connection by exerting pressure on at least an actuating surface that can be modified from

elastic way.

  The connector of the invention has in relation to

  existing connectors the advantage that one avoids the incon-

  mentioned above and creates a mechanics of

  locking with a small footprint. For that we

  turns the plug of an element that is split on a part of its periphery and whose surface can be modified

  transverse section by lateral pressure on

  actuating faces. In this way we can achieve locks on the strut both on its side faces as on its transverse faces. We can get

  high locking forces thanks to the great sur-

face of which the element is provided.

  Drawings. The present invention will be described below in more detail with the aid of an embodiment shown in the accompanying drawings in which: - Figure 1 shows in longitudinal section parts of the

  connector with the element in a release position

rustling and

  FIG. 2 shows parts of the connector with the element

  in a locked position.

  Description of the exemplary embodiment

  In Figures 1, 2 there is shown as part of an electrical connection a plug 11 and a strut 12 can be coupled with the first. The connection contains in a known manner and not shown in more detail in the two plugs 11, 12 of the contact elements or against contact elements that come into contact during the junction of the connection. Thanks to the arrangement of the contact elements, the plug 11 and the strut 12 are constituted in their basic form in a square form. Above the plug 11 is arranged an element 13

  bell-shaped with an upper edge fitted with a

  let, element that is snapped on the card 11. The element

  13 is partially divided by slots 14, which extend

  tooth on a part of its periphery. We can by means of a

  actuating surface 16 slide an inferior frame

  closed 17 compared to the residual part of the

  13. In this way, it is possible to lock the plug 11 on a latching element 18 on the frame 17.

  the strut 12 and exerting pressure on a sup-

  opposite operating face 16 can be released the plug 11 of the strut 12. This lock can take place also

  of course on latching elements 18 on the long sides

  only on the transverse faces of the counterfeit

  Due to the large surface area of the element 13, long flexible paths are provided thereon for locking and unlocking so that large locking forces can be exerted during

  a low stress on the material of the element 13.

  Thanks to the frame 17 which does not have a slot 14, a closed protective wall is created all around which forms for the connection when the plug 11 and the strut are joined.

12 a sealing protection.
