Description

TITLE

PLUG WITH PROTECTION

TECHNICAL AREA

The present invention relates to a pin-side connector for electrical connection to a socket-side connector according to the preamble of claim 1.

STATE OF THE ART

For the manufacture of electrical and / or electronic connections between different components, lines or the like plug-in connections are known which consist of a plug-in element and a female element. Often, the plug element in this case has one or more contact elements which are inserted into one or more corresponding socket contacts in the socket element. When fully or partially driven by electric power electric or hybrid vehicles very large currents and / or voltages on the plug-in elements and thus transmitted via the contact elements.

Because of the high currents or voltages particularly high safety requirements are placed on the plug-in elements to prevent inadvertent contact of the contact elements by a human finger. For a corresponding test, a so-called test finger can be used, which corresponds to a prescribed standard IEC 60529 and is pressed with a prescribed test force against portions or openings of the plug element, in which the one or more contact elements are located. In this case, there must be no contact between the live sections of the contact elements through the Prüffmger.

From the prior art, various possibilities are known, such as that such an unwanted contact by a finger can be prevented. For example, from US 8 734 191 B2 a plug with a contact is known, wherein an insulation cap on the contact and lateral protective covers are present, which surround the contact on all sides.

WO 2014/187908 discloses a plug, the contact of which is partially surrounded by a protective cover, and a plug, in which the protective cover is formed integrally with an insulation cap for the contact. However, the provision of protective elements for protection against contact leads to an increased space requirement or lack of space, which is particularly disadvantageous in plugs with a plurality of contact elements.

PRESENTATION OF THE INVENTION

Object of the present invention is therefore to provide a connector which overcomes the disadvantages of the prior art. In particular, a plug is given, which has a compact design. Another particularly preferred object is to provide a connector which gives the best possible and constant electrical contact.

According to the invention, this object is achieved by a plug according to claim 1 or claim 17. It is specified according to claim 1, a pin-side connector for electrical connection with a female connector, comprising a pin-side connector housing with a connector base and a connector wall, an electrically conductive contact pin with a free pin end and a base-side pin end for attachment of the contact pin on the pin side connector housing, and a Protective element, which is designed to be electrically insulating. The protective element is arranged at a distance from the contact pin on the pin-side connector housing.

The protective element prevents unwanted contact of the contact pin by a Fingers or the like.

Due to the distance, it is also possible that the entire peripheral side of the contact pin is electrically encompassed by a socket.

As will be explained below, the pin-side connector can have one or more contact pins, wherein then preferably one or more protective elements are provided. Preferably, a protective element is arranged per contact pin. Statements on a respective contact pin or protective element are therefore to be understood accordingly for one or more contact pins or protective elements.

Preferably, the protective element is formed separately from the contact pin. In other words, the protective element is thus a component formed separately from the contact pin and arranged separately.

Preferably, a not filled with components space area is present between the protective element and the contact pin. The protective element is preferably arranged at a distance such that the protective element does not touch a lateral surface of the contact pin.

The contact pin is preferably cylindrical and extends, starting from the base-side pin end in the direction of the free pin end along a central axis.

The plug wall is preferably designed to be electrically insulating and arranged at a distance from the contact pin on the pin-side plug housing.

The plug wall, preferably the entire pin-side plug housing, can therefore likewise be formed from an electrically insulating material, so that the protective element and also the plug wall together form an electrically insulating covering area for the contact pin. The connector wall can be understood as an additional protective element for the contact pin. Preferably, the protective element is arranged at a distance from the connector wall. That is, it is preferred that the protective element is arranged at a distance from the contact pin and from the connector wall on the pin-side connector housing.

The plug wall extends at least partially along a circumferential direction around the contact pin. The plug wall is preferably in such a way to the contact pin that a test finger can not be inserted between the connector wall and pin. The connector wall can be seen in cross section transverse to the central axis at least partially circular segment or polygonal or rectangular or square or formed from a mixture thereof. Preferably, the connector wall extends in a circular cylindrical about the central axis of the contact pin. The protective element and the connector wall are preferably arranged approximately concentrically or eccentrically around the contact pin. In a concentric arrangement, therefore, the protective element and the connector wall are each arranged at approximately the same distance from the contact pin along a circumferential direction around the contact pin. In an eccentric arrangement, the connector wall extends about an axis which is parallel to the central axis of the contact pin.

The connector wall can be peripherally interrupted and the protective element can be arranged in an interruption of the connector wall or in the region of an interruption. The connector wall can have an interruption, wherein the protective element is arranged in this one interruption. However, the connector wall may also have a plurality of interruptions, so that a multi-part connector wall extends around the contact pin around, wherein the individual parts of the connector wall are arranged at a distance from each other and the protective element is preferably arranged between two such parts.

But it is also conceivable that the connector wall is circumferentially not interrupted and instead formed in one piece. Preferably, the protective element has a first portion oriented along a first direction and a second portion oriented along a second direction, particularly at an angle to the first direction, and provided for reinforcement against deformation of the first portion. In the case of a touch of the first portion of the protective element by a finger or the like thus ensures the second portion of the protective element that the first portion, in particular the entire protective element, not deformed or bent due to the contact pressure. The protective element is preferably formed substantially U-shaped, wherein the first portion is formed by a base leg and the second portion by two of these projecting, opposite side legs, wherein the side legs facing the contact pin. The first direction preferably extends perpendicular to the center axis of the contact pin, and the second direction preferably again extends perpendicular to the first direction.

Preferably, the protective element, in particular the base leg and the side legs, and / or the connector wall, extending from the connector base in the direction of the free end of the contact pin, substantially along an entire length of the contact pin.

The base leg preferably has a width seen transversely to the central axis, which substantially corresponds to a width of the contact pin. That is, the base leg covers substantially an entire width of the contact pin.

Preferably, the protective element has a length which is at least as long in the direction of the central axis as the contact pin in the same direction. Particularly preferably, the protective element is designed to be longer than the contact pin. It is preferred that the connector wall has two parallel wall surfaces on its inner surface facing the contact pin, which parallel wall surfaces are arranged opposite one another with respect to the central axis extending from the base-side pin end in the direction of the free pin end along the contact pin are and / or are each arranged at an equal distance from the central axis.

The connector wall preferably has an arcuate portion which connects the two parallel wall surfaces arcuately with each other. The parallel wall surfaces are preferably rectangular and extend from the base-side pin end in the direction of the free pin end along the entire length of the connector wall.

Preferably, the protective element is arranged with respect to the connector wall in a plane which is defined by the central axis and by a arc center of the arcuate portion, and wherein the protective element is arranged centrally in this plane between the parallel wall surfaces.

In other words, the protective element is arranged in an interruption of the connector wall, wherein the arcuate portion of the connector wall on the opposite side of the protective element and the two parallel wall surfaces are arranged on the protective element adjacent sides of the interrupted connector wall. The plug wall may have on the outside or inside in the region of the parallel wall surfaces in each case via grooves. These grooves can be formed, for example, in the form of elongate slots, which extend from the plug base in the direction of the free pin end substantially along the entire length of the connector wall. By Einrillungen the connector wall can be strengthened. This in particular under the proviso of a simplified production by means of an injection molding process. Preferably, the grooves are formed so that no excessive accumulation of material is provided, but demioch a mechanically solid wall is provided. The grooves have the particular advantage that the connector wall is mechanically robust with respect to transverse forces which are applied by a test finger.

Preferably, the protective element and / or the plug wall is formed integrally with the plug housing and form a protective arrangement for the contact pin. Preferably, the pin-side connector has two or more contact pins, each contact pin each having a protective element, preferably also at least one respective connector wall, in particular preferably each having a protective arrangement. That is, a protective arrangement is preferably provided for each contact pin.

Preferably, for this purpose, the protective element and the plug housing in one production step, in particular simultaneously, manufactured in one piece. However, it is also conceivable that the protective element is manufactured separately from the plug housing and is guided, for example, through a corresponding recess in the plug base through the pin-side plug housing and secured therein after manufacture. It is also conceivable that the protective element and / or the connector wall are manufactured separately and are subsequently arranged on an electrically insulating protective element base which extends at least partially or completely around the contact pin.

Preferably, an electrically insulating contact protection, preferably in the form of a protective cap, is arranged on the free end of the contact pin.

Further, according to claim 1 1 a socket-side connector for electrical connection with a pin-side connector as described above. The socket-side connector has a socket-side connector housing with a connector base and a connector wall, and a socket which is arranged in the socket-side connector housing and is designed to receive the contact pin in the connected state. The socket-side connector housing has a receptacle for receiving the protective element in the connected state.

When the pin-side connector and the socket-side connector are connected to each other, the protective member is accommodated in the receptacle of the socket-side connector, and a connector system having a compact construction is provided. Again, it should be understood that the socket-side connector may have one or more sockets and receptacles depending on the number of pins or protective arrangements of the pin-side connector. Preferably, the receptacle frames the protective element in the connected state at least partially, wherein the protective element is preferably accommodated in the receptacle in an exact fit and / or wherein the receptacle is preferably designed to receive the substantially entire length of the protective element. The receptacle preferably has a substantially rectangular shape, the inner surfaces of which have play in the connected state to the outer surfaces of the protective element. Preferably, the receptacle surrounds the protective element substantially completely in the region of the receptacle. For example, for snug receiving a U-shaped protective element as described above, the protective element facing the inner shape of the receptacle may be formed such that it has a curved corresponding to the curved base leg of the protective element inner surface, and about two corresponding to the straight side legs of the protective element straight , parallel aligned inner surfaces has.

The socket-side plug housing preferably has a further, in particular circular, recess, into which the particular circular segment-shaped plug wall can be received. In the case of one or more contact pins, the socket-side connector housing preferably also has one or more recesses.

Preferably, a contact element, in particular a contact blade, arranged in the socket, which is designed for electrical contact with the contact pin of the pin-side connector.

In the connected state, therefore, an electrical contact between the contact pin and the socket takes place via the said contact element. Preferably, the socket is arranged in a conductor element. The said receptacle for the protective element extends into the conductor element. In other words, the conductor element has a recess into which the receptacle of the protective element extends. Consequently, the protective element thus projects through the receptacle of the plug element and through the recess in the conductor element. The current path in the conductor element extends laterally to the recess.

Preferably, said recess is located below the socket.

Particularly preferably, the receptacle in the conductor element is arranged such that the protective element is not surrounded on its peripheral side but not on its front side by the conductor element. The peripheral side is the side of the protective element which is formed by parts of the lateral surface extending around the central axis. The front side is the side of the protective element, which is oriented at right angles to the central axis and the protective element terminates towards the front.

Due to the fact that the receptacle extends into the conductor element, there is the advantage that the socket side can be made more compact.

The receptacle is provided in the particularly preferred embodiment both by the socket-side connector housing and by the conductor element. Preferably, the conductor element has a connection region for a cable and in particular is formed at an angle or parallel to the connector base of the socket-side connector housing. For example, the connection region can be arranged perpendicular to the connector base. In the case of the right-angled embodiment, the arrangement of the recess in the conductor element is particularly advantageous because then the protective element can protrude into the recess in the insertion direction.

Analogously, the pin-side connector also have a connection region for a cable, which is also angled, in particular perpendicular, or parallel to the pin-side Plug housing can be formed.

Further embodiments are given in the dependent claims.

DESCRIPTION OF PREFERRED EMBODIMENTS

Figures 1 to 4 show different views of a pin-side connector S and a socket-side connector B individually (Figures 1 and 2), in the unconnected (Figure 3) and in the connected state (Figure 4).

As can be seen in particular from FIG. 1, the pin-side plug S has a pin-side plug housing 6 with a plug base 61 and a plug wall 62, 62 '. The plug housing 6 is arranged here on a pin-side socket 2, which in turn has a housing socket 21 and a housing base 22. On the plug base 61, two electrically conductive contact pins 3, 3 'are arranged, each of which has a free pin end 31, 31 and a base-side pin end 32, 32'. The contact pins 3, 3 'are fastened with their base-side pin end 32, 32' on the pin-side connector housing 6. Furthermore, two electrically insulating protective elements 5, 5 'are provided, which are each arranged at a distance from the contact pins 3, 3' on the pin-side plug housing 6. The pin-side connector housing 6 here has a circular segment-shaped connector wall 62, 62 ', wherein in each case a circular segment-shaped wall 62, 62' at least partially surrounds a contact pin 3, 3 'along a circumferential direction about the respective contact pin 3, 3'.

Although in the figures shown here two contact pins 3, 3 'with corresponding protective elements 5, 5' and connector walls 62, 62 'are shown, only such a contact pin with a protective element and a connector wall or three or more such pins each having three or more protective elements and three or more connector walls can be provided.

The plug walls 62, 62 'and the protective element 5, 5' are arranged such that it is prevented that a test finger or even a human finger can touch the contact pin 3, 3 '.

The protective element 5, 5 'is in each case formed separately from the contact pin 3, 3' and arranged so spaced from the contact pin 3, 3 ', that it does not touch the lateral surface 33, 33' of the cylindrical contact pin 3, 3 '. The plug wall 62, 62 'of the pin-side plug housing 6 is also formed electrically insulating and spaced from the contact pins 3, 3' and of the protective elements 5, 5 'arranged on the pin-side connector housing 6. The plug wall 62, 62 'can thus be understood as a further electrically insulating protective element for preventing unwanted contact of the contact pin 3, 3'.

The protective elements 5, 5 'and the connector walls 62, 62' are each arranged concentrically around the corresponding contact pin 3, 3 'and extend from the pin-side connector base 61 in the direction of the free end 31, 31' of the contact pin 3, 3 'substantially along an entire length LK of the contact pin 3, 3'.

As already mentioned, the connector wall 62, 62 'extends only partially around the connector wall Contact pin 3, 3 'around and has an interruption 63, 63', wherein the protective element 5, 5 'in the region of this interruption 63, 63' on the pin-side connector housing 6 is arranged. In the embodiments shown here, the plug wall 62, 62 'peripherally interrupted exactly once, although several such interruptions are conceivable. The protective element 5, 5 'is in each case arranged at the same radial distance from the contact pin 3, 3' as the plug wall 62, 62 'is arranged to the contact pin 3, 3'.

The protective element 5, 5 'here is substantially U-shaped and has a first portion 51, 51' in the form of a base leg, which extends along a first direction Rl. Furthermore, the protective element 51, 5 has a second section 52, 52 '53, 53' in the form of opposing side limbs, which project from the base leg 51, 51 'and extend along a second direction R2. In the case of a U-shaped protective element 5, 5 ', the second direction R2 extends substantially perpendicular to the first direction Rl. In other words, the side legs 52, 52 '53, 53' are arranged substantially perpendicular to the base legs 51, 5 and thereby the contact pin 3, 3 'facing. The side legs 52, 52 '53, 53' serve to reinforce the base leg 51, 51 'against deformation of the base leg 51, 51'. The base leg 51, 51 'here has a width BS, which essentially corresponds to a width BK of the contact pin 3, 3'.

The length of the protective element 5, 5 'seen in the direction of the central axis M is preferably greater than the length of the contact pin. The contact pin extends substantially in the direction of the central axis or the lateral surface of the contact pin.

The outer shape 54, 54 'of the U-shaped protective element 5, 5' is designed such that the base leg 51, 51 'has a curved outer surface 54, 54', while the side legs 52, 52 '53, 53' each with straight, parallel to each other aligned outer surfaces 54, 54 'are provided. The contact pin 3 facing the inner mold 55, 55 'of the U-shaped protective element 5, 5', however, is such that both the base leg 51, 51 'as well as the side legs 52, 52' 53, 53 'each have straight inner surfaces 55, 55 ', wherein the inner surfaces 55, 55' of the side legs 52, 52 '53, 53' substantially perpendicular to the inner surface 55, 55 'of the base leg 51, the fifth stand. As can be seen in particular from FIG. 1, the lateral limbs 52, 52 ', 53, 53' each have, at their free ends 57, 57 'facing the contact pin 3, 3', an oblique end surface, which respectively starts from the outer surface 54, 54 'of the Side legs 52, 52 '53, 53' in the direction of the inner surface 55, 55 'of the side leg 52, 52' 53, 53 'are inclined.

The plug wall 62, 62 'of the pin-side plug housing 6 has on its the contact pin 3, 3' facing inner surface 64, 64 ', two parallel wall surfaces 65, 65', with respect to a starting from the base-side pin end 32, 32 'in the direction of the free Stiftendes 31, 31 'along the contact pin 3, 3' extending central axis M arranged opposite to each other and are each arranged at an equal distance from the central axis M. In addition, the plug wall 62, 62 'has an arcuate portion 66, 66', which connects the two parallel wall surfaces 65, 65 'arcuately with each other. The wall surfaces 65, 65 'can be arranged on the inside and outside. The protective element 5, 5 'is arranged with respect to the plug wall 62, 62' in a plane E, which is defined by the center axis M and by a center of arc B of the arcuate portion 66, 66 'of the plug wall 62, 62'. The protective element 5, 5 'is arranged centrally in this plane E between the parallel wall surfaces 65, 65'. In other words, the plug wall 62, 62 'with its arcuate portion 66, 66' and with the parallel wall surfaces 65, 65 'having portion formed substantially circular segment, wherein the protective element 5, 5' in an interruption 63, 63 'and in particular on a circular line of this circular segment-shaped connector wall 62, 62 'is arranged. The arcuate portion 66, 66 'extends about an axis parallel to the central axis.

Next, the connector wall 62, 62 'on the outside, so on its housing 21 facing the outside, in the region of the parallel wall surfaces 65, 65' in each case a grooving 67, 67 '. These grooves 67, 67 'are in the form of elongated slots which, starting from the plug base 61, extend in the direction of the free pin end 31, 3 substantially along the entire length of the plug wall 62, 62'. In the embodiment shown here, the protective element 5, 5 'and the plug wall 62, 62' are formed integrally with the plug housing 6 and these together form a protective arrangement 8, 8 'for the contact pin 3, 3'. As already mentioned, two contact pins 3, 3 'with corresponding protective elements 5, 5' and connector walls 62, 62 'are shown in the figures shown here, whereby only one such contact pin with protective element and connector wall or several such pins with respective protective elements and Connector walls can be provided. Accordingly, a protective arrangement for one contact pin or two or more protective arrangements for two or more contact pins may be provided. In other words, an associated protective arrangement is provided per contact pin.

At the free end 31, 3 of the contact pin 3, 3 'is in each case an electrically insulating protective cap 4, 4' is provided, which serves as an additional electrically insulating contact protection against accidental contact of the contact pin 3, 3 '. The protective cap 4, 4 'extends completely around the central axis M around covered the entire free end 31, 31' of the contact pin 3, 3 '. Due to the protective arrangement 8, 8 ', which provides a lateral protection effect for the contact pin 3, 3', and the protective cap 4, 4 ', which provides an upper-side protective effect for the contact pin 3, 3', is a contact of the contact pin 3, 3rd 'essentially impossible.

FIG. 2 shows a socket-side plug B for electrical connection to a pin-side plug S as described above. This socket-side connector B has a socket-side connector housing 9 with a connector base 91 and a connector wall 92. The socket-side plug housing 9 is likewise arranged on a socket-side socket 400, which in turn has a socket-side housing socket 401 and a socket-side housing base 402. A socket 100, 100 'is arranged in the socket-side connector housing 9, which is designed to receive the contact pin 3, 3' in the connected state. Next, a receptacle 93, 93 'for receiving the protective element 5, 5' is arranged in the connected state on the socket side. The receptacle 93, 93 'extends in the present case both through the plug housing 9 and through the conductor element 300. Here, the socket-side connector housing 9 has two such receptacles 93, 93 'for the two pins 3, 3' of the pin-side connector S. If the pin-side connector S has one or more contact pins, the socket-side connector housing 9 has one or more receptacles. In other words, the socket-side connector housing 9 thus has one receptacle per contact pin.

As can be seen in particular from FIG. 4, the protective element 5, 5 'in the connected state is snugly received in the receptacle 93, 93' of the socket-side plug B, the receptacle 93, 93 'at least partially framing the protective element 5, 5'. The receptacle 93, 93 'for this purpose has a substantially rectangular shape, the inner surfaces 94, 94' in the connected state, the outer surfaces 54, 54 'of the protective element 5, 5' at least partially surrounds.

For snug receiving of a U-shaped protective element 5, 5 'as described above, the inner mold 94, 94' of the receptacle 93, 93 'facing the protective element 5, 5' is designed such that it has a correspondingly bent base leg 51, 51 '. has curved inner surface, as well as two corresponding to the straight side legs 52, 52 ', 53, 53' straight, parallel to each other aligned inner surfaces has.

In addition to the receptacle 93, 93 'of the protective element 5, 5', the socket-side plug housing 9 has a further, in particular circular, recess 95, 95 ', in which the particular circular segment-shaped plug wall 62, 62' can be accommodated. This recess 95, 95 'here extends completely around the bushing 100, 100' and the receptacle 93, 93 'around. Again, it is to be understood that one socket and one recess per contact pin is provided in each case.

Thus, the pin-side connector S and the female connector B can be assembled to form a connector system 1, wherein each pin 3, 3 'and each associated protective device 8, 8' of the pin-side connector S in corresponding receptacles 93, 93 'or recesses 95, 95' the socket-side connector B, as well as the housing 21 of the socket-side socket 2 are received in the housing socket 401 of the socket-side socket 400, so that one outwards completely completed plug-in connection is formed.

As can be seen in particular from FIGS. 4 and 5, a contact element 200, here in the form of a contact lamella, is arranged in the bushing 100, which is designed to make electrical contact with the contact pin 3 of the pin-side plug S. The contact lamella preferably extends completely along the entire circumferential direction of the bushing 100. The bushing 100 in turn is arranged in a conductor element 300 which has a connection region 301 for a cable and in the embodiment shown here is formed perpendicular to the plug base 91 of the socket-side plug housing 9 , Instead of a connecting region 301 formed perpendicular to the plug base 91, a connection region arranged parallel to the plug base 91 may also be provided.

The conductor element 300, as explained above, provides a part of the receptacle 93, 93 '. The recording penetrates the conductor element 300, whereby its cross-section is weakened. The current path runs laterally to the receptacle 93, 93 '. The arrangement of the receptacle 93, 93 'in the conductor element 300 has the advantage that the conductor element 300 can be provided very simply. In other words, the protective element 5, 5 'penetrates the conductor element, which has the advantage that the conductor element 300 does not have to be constructed around the end face of the protective element 5, 5'. That is, the conductor element 300 surrounds the protective element 5, 5 'around its peripheral side or laterally, but not around the end face or the proximal end of the protective element. This allows the housing to be made more compact. Although not shown in the figures, the pin-side connector S may also have a connection region for a cable, which may also be arranged parallel or at an angle, in particular perpendicular, to the pin-side connector housing 6.

The male or female housing or other male housing and female housing described above are typically manufactured by an injection molding process. The socket-side plug housing 9 comprises a shield 500. The shield 500 is molded onto an outer part 501 and / or an inner part 502. The most preferred method is as follows. The inner part 501 of the shield 500 is first molded onto the shield 500. Thereafter, the outer part 502 of the shield 500 is molded. The shield 500 could also be sprayed on an outer part 502, wherein subsequently the inner part 501 is injected.

In particular, in the case of multi-pin connector, the outer part and the inner part can also be injected gleichzeigt to the shields. Thus, the shields are housing in a single plug.
