PLUG CONNECTION WITH BACKLASH-FREE PRELOAD

Abstract

Plug-in connection, comprising a plug-in connector (1) which can be plugged together with a mating plug-in connector, M also known as a pin housing (2), it being possible to at least indirectly lock the plug-in connector (1) with the mating plug-in connector (2), characterised in that a bushing housing (3) is provided which at least partially surrounds the plug-in connector (1) and provides the locking with the mating plug-in connector or pin housing (2), and in that the plug-in connector (1), the mating plug-in connector or the pin housing (2) and the bushing housing (3) are operatively interconnected by means of a lever mechanism and can be braced together.

Claims

1. A plug connection comprises: a main connector; a mating connector latchable at least indirectly to the mating connector; a sleeve is provided at least partially engaged around the main connector latchable to the mating connector or pin housing; and a lever mechanism operatively connecting the main connector, the mating connector, and the sleeve to one another and are thereby bracing the sleeve and connectors against each other.

2. The plug connection according to claim 1, further comprising: an end stop on the sleeve and/or on the main connector and limiting displacement of the sleeve on the main connector toward the mating connector.

3. The plug connection according to claim 1, wherein the lever mechanism has a lever that is fixed in a central region so as to be pivotable on the main connector and is connected with its ends to the pin housing and the sleeve.

4. The plug connection according to claim 1, wherein the lever has at one of its end a pin that, after insertion into a slot on the sleeve or on the mating connector, can be displaced therein.

5. The plug connection according to claim 4, wherein the lever has at its other end a slot that, after insertion of a pin on the mating conductor or on the sleeve, engages around the latter.

6. The plug connection according to claim 1, further comprising: a spring on the lever on an edge of the slot facing the pin housing that spring loads the pin housing toward the main connector.

7. The plug connection according to claim 6, wherein the spring is a leaf spring.

Description

[0009] In a further embodiment of the invention, reference is made to the drawing in which an embodiment of the invention is illustrated in a simplified manner. Therein:

[0010] FIG. 1 is a perspective view of the plug connection at the start of contacting,

[0011] FIG. 2 shows the plug connection after joining the main plug connector to the mating plug connector,

[0012] FIG. 3 shows the plug connection according to FIG. 2 with the sleeve latched on the mating connector and

[0013] FIG. 4 is a large-scale view the lever with a built-in spring.

[0014] In FIGS. 1 to 4, reference numeral designates a main connector 1 that contacts a mating connector or pin housing 2 and thereby establishes an electrical connection. A sleeve shown at 3 is displace on the main plug connector 1. A lug 4 on the main connector 1 forms a stop that limits displacement of the sleeve 3 on the main connector 1 toward the pin housing 2.

[0015] The main connector 1 has a pivot 5 on which a lever 6 is mounted. At its one end, the lever 6 has a pin 7 that fits in and slides along a slot 8 of the sleeve 3. A slot 9 formed on the other end of the lever 6 fits with a pin 10 on the mating connector or pin housing 2.

[0016] At the start of contacting, both the pin 7 and the pin 10 engage in the respective slots 8 and 9, so that a lever action is generated by a force acting on the sleeve 3 toward the pin housing 2, which lever action draws or pushes the main connector 1 and the mating connector or pin housing 2 toward each other.

[0017] As soon as the sleeve 3 reaches the lug 4 on the main connector 1, the contacting is completed and the sleeve 3 engages with a tab behind a ramp on the mating connector or pin housing 2.

[0018] The increase in the clamping force and permanent bracing between the main connector 1 and the mating connector or pin housing 2 is aided by a spring 11 that is installed on the edge of the slot 10 in the lever and is designed as a leaf spring. The bracing is permanently possible because the other end of the lever 6 is supported via the sleeve 3 and the sleeve 3 in turn is fixed to the mating plug connector or pin housing 2 via the latch.

[0019] There are at least one here unillustrated mating contact partner in the main connector 1 as well as in the mating connector 2 or pin housing that together form an electrical connection when the main connector 1 has been plugged together in the manner described above with the mating connector 2 or the pin housing.

[0020] The at least one contact partner of the main connector 1 and/or the at least one mating contact partner of the mating connector 2 or of the pin housing are mounted, for example, at the end of a respective cable, but can also be arranged on a board of an electronic device or the like.
