EP1427067A2 - Plug with slider for connection with a receptacle - Google Patents

Abstract

When the connector is not in a completely mounted state, a spring (26) holds a slider (29) with its holding stop piece (35) under a biasing force against a stop-piece (23) associated with a locking arm (20). When the completely mounted state is reached, a locking catch (9) in the socket releasably moves to a second position under the action of the spring.

Description

The invention relates to a plug with slider for connecting to a socket. The connection should be made with a socket, which is a socket housing with a first longitudinal axis and with one enclosed by a wall Receiving space which, to an end face of the socket housing open and closed at the far end by a bottom. The socket housing first contacts are assigned. These can be, for example be provided in by pins, in the receiving space from the ground protrude parallel to the first longitudinal axis. On the outer surface of the recording room enclosing wall is arranged projecting at least one locking lug. This points in the direction away from the end face to the bottom of the Outside surface removing rising run-up surface, to which in the direction to the bottom adjoins a latching surface extending in the direction of the outer surface.

EP 0 896 396 A2 describes a plug connector which has a socket and a plug. The socket has a female connector housing and a receiving space enclosed by a wall. This is to a face of the female connector housing open and at its end remote to closed a floor. The socket has a first longitudinal axis, the defines a connection direction. The socket housing are first contacts assigned. These are aligned parallel to the first longitudinal axis and stand by the Floor in the receiving space in front. On the outer surface of the receiving space enclosing Wall are a latch and two sides of the same parallel Arranged ribs projecting.

The plug has a plug housing with a first housing portion and a second housing section on. The first housing section occurs when connecting with the socket in their recording room. The second housing section is arranged at a radial distance from the first housing section, so that between both a clearance exists, which receives the wall of the female connector housing. The second housing portion of the plug is an elastically deflectable latch arm assigned, which can be locked via a pen, when he is in the locking position is, wherein the spring holder is a deflection of the locking arm prevented from the relaxed position.

The spring holder compression springs are assigned, which are not supported on her at this End connected to each other via a crossbar. The locking arm has an inclined surface, the insertion of the plug into the socket against the Latch is running. The pen is in an advanced position, in which its locking surface is not in contact with the locking arm. He will be in this Position on the connector housing held by elastic arms with locking lugs. Becomes the plug inserted into the socket, then not only the locking arm comes with his hook-like projection against the latch, but also the Traverse, the the two compression springs together, comes to rest against the ribs the socket. If the plug continues to be inserted, the springs are pretensioned. The hook-shaped locking element of the locking arm slides over the Locking lug. Here, the locking arm has reached a position in which its locking surface can engage behind the latch. At the same time, the compression springs in their Effect released, i. the holding means forming elastic arms have up the outer surface of the receptacle housing moves and are out of control for Plug housing so that they release the pen and this due to the effect The spring is moved away from the detent, creating the latch surface the spring holder passes over the locking arm and this in its engaged position secures against deflection. In this case, the holding means in the form of the pen molded arms with hooks in their original position, so that the springs are relieved again. To release, the pen must opposite to the loosening direction of the plug moved to the connector housing so that the locking arm is released. So that a sufficiently large contact area given for the support of the compression springs are on the socket housing the ribs provided in extension of the course of the compression springs are arranged, i. extend parallel to each other in the connecting direction and go out from the face of the socket and reach up to the catch.

For releasing the spring holder is first as far in the direction of the socket shifted, that the locking arm is released. This will be the compression springs partially biased and the arms set the pen in this position. In this position can be pressed on an unlocking portion of the spring holder be, with this section on an underlying projection of the locking arm acts. Since the locking arm is formed like a rocker, it will be hook-like Projection out of engagement with the latch on the socket moves. Will now pulled the plug, this can be separated from the socket. The Handling is cumbersome and requires, especially if a safer Operation is required, additional measures in the form of ribs on the socket, for a secure support for the compression springs, which act on the pen, to reach. Unfavorable handling is also insofar as when loosening the Plug from the socket of the spring holder initially against the release direction has to be moved in order to transfer it to a position in which this associated actuating portion a force on the locking arm in the sense of Lösens of the catch of the socket can be introduced. simultaneously must then be pulled on the plug to release it from the socket. This means that the release direction of the plug from the socket and the Movement of the spring holder in the release position for the locking arms opposite to each other are.

This is not user-friendly for one-handed operation. In many applications an automatic disconnection of the plug from the socket is not required.

The invention is based on the object, a plug for a conventional socket, i.e. one in which at least one latch is provided to propose which is easy to handle and makes it clear whether a final Connection of the plug to the socket is reached or not.

• a connector housing,
  which has a second longitudinal axis,
  which has a first housing section that can be inserted into the receiving space when the longitudinal axes are aligned parallel to one another,
  having a second housing portion,
  which has an elastically deflectable locking arm, which is integrally connected to the second housing portion and which faces the latching nose when connecting to the socket housing, and
• a slider,
  which is held on the connector housing along the second longitudinal axis limited adjustable between two positions, and
  which is acted upon by at least one spring, which has a holding stop,

wherein in the not or not fully connected state of the plug in a first position, the spring holds the slide with its retaining stop biased against the first arm associated with the locking stop, from which he reaches the fully connected state between the plug and the socket by one of Latches of the socket detachably and under the action of the spring in a fully connected state representing the second position can be transferred.

An advantage of this design is that the plug in conjunction with usual Sockets can be used, which have at least one locking lug, so that without change to the same is guaranteed that the final connection of the plug with the socket is displayed. This will be for the fitter Both visible and palpable when connecting. The visual inspection is by the advanced Position of the slider allows. This is felt by the fact that the Slider advances forward towards the socket. The release of the slider takes place automatically as soon as the locking arm has been released by the locking lug and moves into the locking position behind the locking lug. The holding stop is from the latch also deflected and can move across the latch arm, due to the force of the between the connector housing and the Slider effective compression springs. The slider is thus relative to the socket housing and moved to the connector housing.

Preferably, it is provided that the holding stopper connected to the slider Holding arm is assigned. This makes it possible to use the slider itself to design relatively solid and to make the arm itself elastic, so that this approaching the retaining stop to the locking lug of the socket is elastically deformed and immediately following the relaxation of the locking arm after passing the locking lug can slide over the locking arm.

It is preferably provided that the locking arm two parallel to the second longitudinal axis extending and spaced apart longitudinal struts and a transversely extending to the locking strut, wherein the two longitudinal struts respectively connected at one end to the second housing portion and to their free ends are interconnected by the locking strut. The first stop is assigned to the locking strut and practically corresponds to the section the locking strut, which comes into contact with the latching surface of the locking lug of the socket.

It is favorable if the second housing section has a guide by means of the slider is adjustably supported along the second longitudinal axis. Preferably the holding arm between the two longitudinal struts is arranged and elastic bendable. Additionally or alternatively to the guide used for guiding the slider is provided on the second housing portion, a guide can the latch arm be assigned. Here, the slider can be used to over the guide act on the locking arm, for example, this from the locking position in to transfer the lifted from the latch release position when the slide located in the first position.

Conveniently, if the slider is used in the second position, an elastic Relocation of the locking arm to prevent. There is then the possibility the locking between the locking surface of the locking lug and the locking arm in such a way that the connection between the two is canceled if the Plug pulled out of the socket by applying a force by hand becomes. However, the prerequisite is that the slider has released the locking arm. to Lock the locking arm, the slider has at least a portion of the sitting in the second position above the latching web and / or one of the longitudinal struts.

Furthermore, it is provided in an embodiment of the invention that the connector housing a first spring support bearing for the first end of the spring and that the Slider a control arm with a second spring support bearing for the second end of the Spring has.

A preferred embodiment of the invention is schematically in the drawing shown.

A conventional socket 1, which is connectable to the housing of a device is in Figure 1 shown. The socket 1 comprises a socket housing 2, which has a has first longitudinal axis 3. It also has a wall 4, one in the opening cross-section approximately rounded rectangular receiving space 5 encloses. This is open to the end face 6 and at the opposite end by the Floor 7 closed. From the bottom 7 are (not visible) first connection contacts in the form of pins or tongues. They are aligned parallel to the first longitudinal axis 3. On the outer surface 8 of the wall 4 at least one locking lug 9 is arranged, which has an oblique contact surface 10 in the direction of the end face 6, the from its end face 6 facing the end towards the bottom 7 out from the outer surface 8, i. rising, runs. This one joins one Detent surface 11, which extends in the direction of the outer surface 8.

In Figure 2, the plug housing 13 of the plug 12 is shown. This owns the second longitudinal axis 14. It has a first housing portion 15, the at Connecting with the socket 1 in the receiving space 5 according to Figure 1 occurs. In this case, the first longitudinal axis 3 and the second longitudinal axis 14 are aligned with each other. The first housing section 15 starts from an end face 16 in which openings are present, which communicate with contact receiving chambers, in which are not shown second contacts in the form of socket-shaped terminals are recorded and secured.

A second housing section 18 adjoins the first housing section 15, from which an outer wall 19 emanating from the first housing portion 15 a Free space 17 for receiving the wall 4 in the connected state of the socket. 1 with the plug 12 leaves free. The second housing portion 18 is the end surface 16 removed integrally formed with the first housing portion 15. The cross section of the first housing section 15 is substantially that of the receiving space 5 the socket housing 2 of the socket 1 adapted, d. H. he is approaching Cross section of a rounded rectangle. The second housing section 18 a locking arm 20 is formed, which is designed like a frame and two longitudinal struts 21, which are arranged at a parallel distance from each other and with an am End with the second housing portion 18, away from the end surface 16, in one piece are formed. The end face 16 near the ends of the two longitudinal struts 21 are interconnected by a transverse locking strut 22, which for latching by means of a first stop 23 with the detent 9 of the socket 1 serves. It sits with the first stop 23 in the connecting direction (insertion direction) of the plug 12 with the socket 1 behind the locking surface 11. Die Locking strut 22 has a footprint 24 at its front edge.

Furthermore, it can be seen from FIG. 2 that the side of the longitudinal struts 21 of the locking arm 20, two first spring support bearings 25 are arranged, which are for the support of as compression springs designed springs 26 serve at one end, with only one spring 26 and a Spring support bearings 25 are visible. In guides 27 of the second housing section 18 and a guide 27 which is connected to the latch arm 20 is a slider 29 kept adjustable along the second longitudinal axis 14 within limits.

The design of the slide 29 results in particular from FIG. 3. It can be seen that that the slider 29 two parallel actuating arms 31 and at each a second Spring support bearing 30, where the springs 26 each with its second Support the end. Laterally on the slide 29 stop projections 32 are on the outside present, the movement of the slider 24 in the assembled state on the connector housing 13 in the direction of the first housing portion 15 by a stop on Limit second housing portion 18. The slider 29 further has an actuating projection 30, which in a breakthrough in the second housing portion 18th exposed to the outside for the operation by hand.

The slide 29 has a holding arm 34 between the two actuating arms 31, which has a holding stop 35 at its free end, with which he is in his first position against the first stop 23 of the locking strut 22 of the locking arm 20th supported. The support arm 34 is in a direction transverse to its longitudinal axis, i. also transversely to the second longitudinal axis 14 adjustable so that it out of engagement with the first Stop 23 can be brought. The holding arm 34 is with its holding stop 35 aligned to the latch 9. In the connected state of the support arm 34 is how 5, over the locking strut 22 of the locking arm 20 and prevented Thus, a release of the locking arm 20 of the locking lug 9 of the socket 1. Der Slider 29 takes its second position.

To connect the socket 1 with the plug 12, these two are so to each other aligned, that the first longitudinal axis 3 with the second longitudinal axis 14th matches.

The plug 12 is aligned with its first housing portion 15 with each other Longitudinal axes 3, 14 inserted into the receiving space 5 of the socket 1. When the position shown in Figure 4 is reached, the locking arm 20 stands with its locking strut 22 of the contact surface 10 of the locking lug 9 on the outer surface 8 of Socket in contact. The slider 29 is located in the illustrated in Figure 2 Position, i. the holding stop 35 is supported against the first stop 23rd of the locking arm 20 from. If now the plug 12 is moved further into the socket 1, is the locking arm 20 by the contact of the locking strut 22 with the contact surface 10 of the latch 9 raised until he has passed this and due to his Elasticity again the outer surface 8 of the wall 4 of the female connector housing second can approach. Immediately following the locking strut 22 is also the holding arm 34 in contact with the contact surface 10 of the locking lug 9, so that the holding arm 34 elastic is deformed, wherein the retaining stop 35 from the outer surface 8 of the Wall 4 of the female connector housing 2 removed and due to the on the slide 29 acting springs 26 also passes over the locking strut 22 away and, as can be seen from Figure 5, in the final connected state of the plug 12 and socket 1 in front of the locking strut 22 sets. The slider 29 takes his second position. The springs 26 are relaxed and the locking arm 20 is in his Locking position secured to the locking lug 9. He is on a take off from the Latch 9 prevented by the support arm 34. If the connection should be solved, so must be acted on the slider 29 so that it is shown by the in FIG second position retracted to the first position shown in Figure 2 becomes. At the same time pulling the plug housing 13 is acted pulling while the Retaining arm 34 in turn elastically deformed upward away from the outer surface 8 and be holding stop 35 first on the locking strut 22 and then the Latch 9 moved away until he, as well as the locking arm 20 now bent freely can also be initially upwards away from the detent 9 away and then springs back again and with its first stop 23, the support base forms for the retaining stop 35 of the support arm 34, as shown in Figure 2 can be seen is.
