It can be dissociably fixed to the connector member, and the corresponding connector member is arranged correspondingly to the lock sleeve, and the corresponding lock portion of the tube shape formed in the corresponding connector member housing is dissociated from the plug connector member to the corresponding connector member. It is provided for possible fixation, wherein the lock sleeve has at least one locking means, and the corresponding locking portion has at least one corresponding locking means formed in a complementary shape. The locking means and the corresponding locking means can be connected to each other, and the lock sleeve can be arranged so as to surround the corresponding locking portion when the plug connector member is connected to the corresponding connector member, and the corresponding locking portion. The lock sleeves can interact with each other by rotation with respect to the lock sleeve, which engages in the inner groove of the lock sleeve and the outer groove of the connector member housing and is supported by the connector member housing and / or the lock sleeve. The present invention relates to a plug connector member that is held in a connector member housing in the axial direction by using a load spring formed as a corrugated spring, and is particularly housed without play.

The present invention further relates to an electrical plug connection system comprising such a plug connector member.

The electrical plug connector member for coupling to the corresponding connector member and the electrical plug connection system including the plug connector member and the corresponding connector member of the form described at the beginning are known from the prior art. Such a plug connector member and a plug connection system are disclosed in, for example, printed matter, Utility Model No. 202005000229 of Germany and Patent Invention No. 102005026148 of Germany.

The plug-connector coupling disclosed in German Patent Invention No. 102005026148, particularly for a multi-pole electrical lead connection, comprises a first half of the coupling. The coupling half is at least one coupling housing, a contact carrier with a contact element housed in the coupling housing, and a contact carrier and optionally its contact element of at least axial length thereof. It contains an area of the coupling housing that surrounds a portion, and this area is a male thread for selectively screwing a cap nut rotatably coupled to the second coupling half, or The second coupling half is rotatably coupled and has a male thread for connecting the coupling elements configured with the means for quick locking. At this time, in the joint portion of the second coupling half portion with the threadless coupling element, the partial length of the region provided with the male thread of the first coupling half portion located outside the male thread. Are formed with locking means for quick locking, in which corresponding members formed in a complementary shape are arranged correspondingly to the coupling element, at this time the second coupling half. The coupling element of is preferably formed by a threadless sleeve and is axially oriented with a load spring supported by the housing of the second coupling half, particularly a load spring formed as a corrugated spring. It is held, especially without play. The corrugated spring is then supported on the end face of the housing of the second coupling half and, on the other hand, the shoulder portion of the second coupling half on the inner peripheral wall of the coupling element formed as a sleeve. In cooperation with the mounting ring supported by the housing, the end face of the housing and the shoulder on the inner peripheral wall of the sleeve form and define an outer groove of the housing.

On the one hand, the disadvantage of this known plug-connector coupling is that the coupling element, which is held playlessly in the coupling housing by a load spring in the axial direction, is the coupling housing of the second coupling half in the circumferential direction. It does not have a well-defined position for, that is, it may take any position, and on the other hand, additional members are needed to form the outer groove of the housing. ..

A spring elastic ring consisting of a band made of flat metal, known under US Pat. No. 7,625,226, comprises a lock sleeve and a sleeve-shaped connector element housed within the lock sleeve via a thread. Protrusions located in the ring chamber between the rings and distributed over the entire circumference, located within the inner wall of the lock sleeve, and alternately supported by the outer wall of the connector element and the inner wall of the lock sleeve between them. ing. The ring forms a controlled resistance in both directions of rotation during rotation.

In known connection formats, whether the plug connector connected by the user is also properly locked using a quick connection technique in which the plug-in connection is formed by a simple axial connection of the plug connector member. However, it is not clearly clear to the user. That's because users don't get clear feedback.

Starting from the prior art described above, the underlying task of the invention is that the coupling element formed as a lock sleeve has at least one fixed unlock and lock position with respect to the housing it holds. Thus, reaching or leaving these positions is to provide the possibility of being perceptible by the user, preferably by touch or hearing.

According to the present invention, this problem is solved by an electrical plug connector member and an electrical plug connection system having the features of two parallel claims 1 and 5. Other preferred embodiments are described in their respective dependent claims.

According to this, the plug connector member according to the present invention has an anti-rotation device, and the anti-rotation device corresponds to at least one spring element fixed to the outside of the connector member housing and the spring element. It consists of at least one locking latch that is arranged and formed inside the lock sleeve. The anti-rotation device allows tactile and auditory perception, at least when the spring element is locked into the locking latch. The spring element is designed to ensure that the lock sleeve does not rotate undesirably when it is open. This makes so-called "blind insertion" relatively easy for the user. This is because there is no need to visually inspect whether the lock sleeve is in the correct position. The spring element is preferably locked from a preloaded and bent leaf spring cutting member and is non-shiftably located in the outer recess of the connector member housing, at this time of the leaf spring cutting member. The overhang extends beyond the outer recess so that it can engage within the locking latch of the lock sleeve at the locking position of the plug connector member.

Preferably, the spring element has a locking projection directed inward of the lock sleeve, which locking projection is therefore in the unlocked state of the lock sleeve and in the locked state of the lock sleeve, respectively. Locks in the first locking pocket or the second locking pocket provided in. With such a configuration, it is possible to clearly distinguish between the locked state and the unlocked state, and further enable various locking forces during operation.

In order to prevent possible dissociation during vibration, according to another preferred configuration of the plug connector member according to the present invention, the inside of the lock sleeve is locked with a first locking pocket in the unlocked state. A guide curve is placed between the second locking pocket and the spring element so that the lock sleeve can only rotate under external force acting on the lock sleeve. Has a contour that keeps it under spring stress.

In a particularly preferred configuration of the present invention, the contour between the first locking pocket and the second locking pocket is flat in the first region and the second locking pocket in the second region. It is formed so as to rise steeply in the vicinity, at which time the first region is longer than the second region. In the unlocked state, the locking projection is locked in the first locking pocket. When the user begins to rotate the lock sleeve, the contour is designed to be flat in the first region, so that it does not produce an early sound, such as a click sound. However, disengagement from the first locking pocket alone creates a spring stress that is set strong enough to prevent the lock sleeve from rotating automatically. Immediately before the locked state, the contour rises strongly in the second region, which causes the spring element to be completely compressed just before that. When the lock sleeve is further rotated, a sound (click) is generated and the plug connector member is properly locked and positioned with the corresponding connector member.

According to another configuration of the electrical plug connector member, the lock sleeve is axially attached to the connector member housing using a corrugated spring that engages in the inner groove of the lock sleeve and in the outer groove of the connector member housing. It is held without play and is supported by the connector member housing and / or lock sleeve. According to the present invention, it is proposed that the corrugated spring is non-rotatably housed in the outer peripheral groove of the connector member housing or the inner peripheral groove of the lock sleeve. When the corrugated spring is positioned fixedly in the outer peripheral groove of the connector member housing in the circumferential direction, the corrugated spring is rotatably engaged in the inner groove of the lock sleeve. In another case, i.e., the corrugated spring is rotatably engaged in the outer peripheral groove of the connector member housing when the corrugated spring is housed in a fixed position within the inner groove of the lock in the circumferential direction. In both cases, the corrugated spring is the axial spring force of the corrugated spring and / or the outer groove of the connector member housing in each groove in which the corrugated spring is rotatably engaged. It is possible to rotate by applying only the rotational resistance determined by the preload of the corrugated spring inside. Thereby, the corrugated spring that holds the lock sleeve and the connector member housing together has a limited degree of freedom in its mobility with respect to the connector member housing or the lock sleeve. This is a basic prerequisite for a fixed unlock position and / or lock position. Based on the material and process, the connector member housing and lock sleeve have some manufacturing error, such manufacturing error is that the corrugated spring is preloaded, i.e. compressed, and the outer groove of the connector member housing and By being inserted into the inner groove of the lock housing, it is compensated by the corrugated spring.

Preferably, the plug connector member has a corrugated spring that is formed open in the circumferential direction and has a spring gap. This allows the corrugated spring to be flexibly formed in the circumferential direction, thereby being easily introduced into the inner groove of the lock sleeve and the outer groove of the connector member housing to hold the lock sleeve and the connector member housing together. Can be done. The corrugated spring has a wave crest in the axial direction and a wave valley located between them. When pressure is applied to the corrugated spring in the axial direction, that is, when the height of the wave crest or the depth of the wave valley changes, the spring gap of the corrugated spring can change its width. At this time, the height of the wave crest and the depth of the wave valley are larger than the groove width of the outer peripheral groove of the connector member housing and the inner peripheral groove of the lock sleeve. As a result, the corrugated spring is in contact with both edges of the outer peripheral groove and the inner peripheral groove of the connector member housing with equal tightening force. At this time, the dimensional error of the corrugated spring itself does not matter. At each position of the lock sleeve with respect to the connector member housing, sufficient tightening force acts to make it difficult to change the position of the lock sleeve with respect to the connector member housing. As long as the preload of the corrugated spring is greater than the load based on the vibration amplitude, the system does not require another friction brake formed, for example as an elastic ring element. When the lock sleeve in the connector member housing is rotated, the tightening force can be used from the beginning during both the locking process and the unlocking process.

In a preferred embodiment, in the plug connector member, the outer groove of the connector member housing or the inner groove of the lock sleeve has at least one positioning web for the corrugated spring, which is preferably the outer perimeter. It is located on the side of the groove or on the side of the inner groove. Of course, it is not necessary that such a web is provided in both grooves. This is because such a web does not allow the lock sleeve to rotate in the connector member housing. Instead of being located on the side of one of the grooves, the positioning web may project from the bottom of these grooves.

In a variation of the plug connector member, the corrugated spring is preferably oriented relative to the connector member housing or lock sleeve so that the positioning web penetrates the spring gap and thus irrevocably secures the corrugated spring. .. In another variation of the plug connector member, the corrugated spring is preferably oriented with respect to the connector member housing or lock sleeve so that at least one positioning web extends in the wave valley of the corrugated spring. Even in such a configuration, the corrugated spring can be fixed in the inner peripheral groove of the lock sleeve or the outer peripheral groove of the connector member housing so as not to rotate without play or with play in the circumferential direction. The positioning web in the corrugated spring may more preferably form a compression limiting web for the corrugated spring, which limits the axial compression distance of the corrugated spring. Such compression limiting webs in the valley of the waves may be provided in addition to the positioning webs that penetrate the spring gap.

In the embodiment, in the plug connector member, the side surface of the inner peripheral groove of the lock sleeve or the side surface of the outer peripheral groove of the connector member housing is formed in a corrugated shape, and the contour of the side surface is preferably matched to the shape of the corrugated spring. ing. This variation is realized not only in the contour of the corrugated spring, but also in the inner groove of the lock sleeve or the outer groove of the connector member housing where the positioning web described above is not formed to hold the corrugated web non-rotatably. Has been done. With this configuration, an increase in axial spring length during rotation of the lock sleeve with respect to the connector member housing is achieved, thereby applying a load on the corrugated spring with the increase in vibration amplitude in the connector member housing. It no longer causes undesired automatic rotation of the lock sleeve, which in turn ensures that the plug connector member locks with the corresponding lock portion. This is especially true because the wave height of the corrugated spring is greater than the width of the outer groove of the connector member housing or the inner groove of the lock sleeve, and the corrugated spring is compressed in the axial direction to the outer groove and / or inside. It is promoted by being inserted in the peripheral groove.

Preferably, in various embodiments, the at least one locking means of the lock sleeve and the at least one corresponding locking means of the corresponding locking portion are as full threads, as circumferentially split partial threads, or bayonet joints. Or it is formed in the form of a bayonet lock. The lock sleeve and the corresponding lock portion are at least partially engaged with each other in the axial direction when the plug connector member is connected to the corresponding connector member, and can be dissociably fixed to each other by rotation of the lock sleeve. At this time, at least one locking means of the lock sleeve may be formed on the outside or the inside of the lock sleeve. At least one corresponding locking means formed with a complementary shape to the locking means is formed on the corresponding corresponding side of the corresponding locking portion of the corresponding connector member.

In a preferred embodiment, the plug connector member has a rotary stopper on the lock sleeve and the connector member housing that limits the rotational movement of the lock sleeve with respect to the connector member housing. Such a rotary stopper is, of course, simply such that at least one locking means of the lock sleeve and at least one corresponding locking means of the corresponding locking portion are not as full threads, but as partial threads divided in the circumferential direction, or bayonet. It is only meaningful in embodiments of the invention, which are formed in the form of joints or bayonet locks. At this time, the rotation stopper of the lock sleeve is preferably formed by a longitudinal wall extending in the axial direction of the sleeve inner notch, and the rotation stopper of the connector member housing is preferably a housing outer pin protruding in the radial direction. It is formed by the longitudinal sides of the. The circumferential width of the sleeve inner notch is clearly greater than the corresponding width of the housing outer pin. The circumferential width of the sleeve inner notch and the corresponding width of the housing outer pin are preferably selected to provide an unlocked and locked position in which the lock sleeve lock can be rotated between them. .. The unlocked position and the locked position are separated from each other by a typical rotation angle of about 30 ° to 100 °. At the unlocked position, one longitudinal side of the housing outer pin contacts the correspondingly located longitudinal wall of the sleeve inner notch, and at the locked position the other longitudinal side of the housing outer pin is the sleeve inner notch. Is in contact with the other longitudinal wall of the.

A plug connector member having a lock sleeve rotatably supported by the connector member housing and a corresponding connector member are provided, and the corresponding connector member is arranged correspondingly to the lock sleeve and formed in the corresponding connector member housing. The electrical plug connection system according to the present invention, which has a corresponding locking portion of the tube shape for dissociable fixing of the plug connector member to the corresponding connector member, is one of the features described above. Includes a plug connector member with one or more features.

It is formed in shape and cooperates with the corresponding locking means 9 in the locked state of the electrical plug connection system. A contact carrier that cannot be seen from the outside is housed in the connector member housing 3, and the contact carrier includes a plurality of electrical plug-in contacts. The contact carrier is confined in the connector member housing 3 by the closing cap 10.

FIG. 5 shows the plug connector member 2 in a vertical cross-sectional view. In this figure, the corrugated spring 11 and the spring element 12 can be seen. As further recognizable here, the closure cap 10 is screwed into the connector member housing 3. The lock sleeve 4 is rotatably supported by the connector member housing 3 and is held by the corrugated spring 11 acting as a load spring in the connector member housing 3 without play in the axial direction. The spring element 12 forms an additional anti-rotation device for the lock sleeve 4. The spring element 12 is non-dissociably fixed to the outside of the connector member housing 3 and cooperates with the locking latch 15 visible in FIG. This rotation prevention device is effective only at the lock position of the lock sleeve 4 in the connector member housing 3.

It is engaged in the inner peripheral groove 18. In the illustrated embodiment of the present invention, the corrugated spring 11 is rotatably housed in the outer peripheral groove 17 of the connector member housing 3 and rotatably in the inner peripheral groove 18 of the lock sleeve 4. Therefore, the outer peripheral groove 17 of the connector member housing 3 has a positioning web 19, and the positioning web 19 prevents the corrugated spring 11 from rotating with play in the circumferential direction. In addition to the positioning web 19 recognizable in FIG. 6, another positioning web 19, 19'is arranged as can be seen from FIG. 7, and the positioning web 19, 19'has a waveform as a compression limiting web. It limits the compression distance of the spring 11 in the axial direction.

At this time, the positioning web 19 is arranged on the side surface 23 of the outer peripheral groove 17 of the connector member housing 3 in both cases.

The plug connector member 2 according to the present invention has a rotation limiting device for the lock sleeve 4 in the illustrated embodiment. This rotation limiting device can be newly seen in FIG. Therefore, rotation stoppers 24 and 25 that limit the rotational movement of the lock sleeve 4 with respect to the connector member housing 3 are provided. The rotation stopper 24 of the lock sleeve 4 is formed by a longitudinal wall 26 extending in the axial direction of the sleeve inner notch 27, and the rotation stopper 25 of the connector member housing 3 is a housing outer pin protruding in the radial direction.
