Description

Contact socket for an electrical connector

The invention relates to a contact socket for a

electrical connector.

The invention is based on a prior art, according to which electrical connectors usually have a contact insert block, in which one or more elongated contact sockets each as a single contact

are arranged. Such electrical connectors are mechanically and electrically connectable with complementary electrical connectors in which one or more elongated pins are arranged as individual contacts in a contact insert block.

Accordingly, the contact bushes used for mechanical and electrical coupling with a respective complementary trained contact pin. An elongated contact pin is thus mechanically and electrically coupled to an elongate contact socket, i. the contact socket takes on the inside of the contact pin or takes the

Contact pin over its outer circumference the contact socket on. Such electrical contact sockets, also called

Single contacts are described in particular in the standards DIN EN 62196 and DIN EN 60309.

Such contact sockets for an electrical

Connectors thus also consist essentially of an electrically conductive material, conventionally of a metal. The section of a contact socket which serves for coupling or for receiving a contact pin is

hereinafter and in the claims as well

Recording section called.

Such a receiving portion extends from a first end portion, which usually serves for the mechanical and electrical coupling or for receiving an electrical connecting conductor, for example a strand or a wire or a cable. Furthermore, the receiving portion is usually shaped substantially cylindrical and defines a longitudinal axis of the contact socket.

The receiving portion of such a contact socket further has along the longitudinal axis of the electrically conductive material encased, cylinder-like interior with an opposite end of the first end portion into which the electrical contact end of a contact pin, for electrically and mechanically contacting the surfaces of the contact pin with the surfaces in the interior of the receiving section,

to insert or insert.

To improve the mechanical and electrical

Connection between a contact socket and a

Contact pin it is known, in the cylinder-like

Interior of the contact sockets individual, preferably

resilient, wires or lamellae bands or the like of electrically conductive, preferably also resilient, material to be arranged, in particular on separate inserts, where such wires or slats attached, that is fixed or arranged. Such inserts will be also referred to as wire or lamellar cages. They have a plurality of juxtaposed wires or lamellae, preferably a cylinder-like

form a shaped cage or frame or are molded or fixed to such. Further, the wires or lamellae are preferably resilient, in particular by means of appropriate choice of material and / or correspondingly relatively small dimensions, and can therefore develop a clamping action. A complementary,

cylindrical contact pin can thus safely inserted or plugged therein, that is to be picked up and held. The surfaces of the wires or the

Slats are thus brought into a mechanical and electrical contact with the surface of the contact pin.

In the following and in the claims, such an integrated in contact bushes or to be integrated use to improve the electrical and mechanical contact between a contact socket and a contact pin

commonly referred to as "socket inlets", and individual wires or slats formed thereon are generally referred to as "slats". In addition, it should be noted that lamellae can also be formed by the fact that on a cylindrical Aufnahmeeinsat z or a cage or a cylinder-shaped, preferably drawn or bent band or the like on the circumference

longitudinal slots, elevations or depressions on or are attached.

A Aufnahmeeinsat z thus serves to improve both the mechanical and the electrical contact between a Contact socket and a contact pin and provides a high number of contact surfaces due to the large number of individual applied to the inserted contact pin lamellae. It thus allows a low electrical

Contact resistance to a contact pin as well as to the interior of the contact socket.

However, it has been shown to be a permanent one

low contact resistance can not always be guaranteed, because oxidation layers, as well

Dirt layers on the one hand on the surfaces of

Aufnahmeeinsät ze, in particular on the lamellae, as well as on the contact pins can form, which the

electrical contact resistance between the

Aufnahmeeinsät z and the interior of the contact socket as well as between the contact socket and the contact pin can increase significantly over time.

Although as accessories for individual contacts formed by such contact sockets cleaning and lubricating sets for the respective Aufnahmeeinsät z or here

trained slats known. However, these do not solve the causative problem of oxidation and contamination. In addition, just the relatively small-sized slats of Aufnahmeeinsät zen increased wear due to a spark break, when

Contact pins under load, that is at current flow between the contact socket and the contact pin, from the

Contact socket to be pulled. It is therefore an object of the invention to further develop and design a cost-effective female contact of the generic type described above, so that the latter, over a very large number of mating cycles, is a permanently high-performance, in particular continuous,

Power transmission allows, the contact resistance should preferably remain permanently low.

The task is followed by an item

of the independent claims. advantageous

Further developments are the subject of the dependent claims.

The object is accordingly achieved by a contact socket for an electrical plug connector, which is of elongated design and comprises an electrically conductive material each having a shaped first end section and an elongated receiving section extending from the first end section and having a substantially cylindrical shape defining a longitudinal axis Recording and for the mechanical and electrical coupling of an electrical contact end of a complementary to the contact socket formed pin comprises a to be mated with the electrical connector connector.

The shaped receiving portion forms along the

Longitudinal axis of a jacketed from the electrically conductive material, cylinder-like interior, in which a formed with lamellae cylindrical Aufnahmeeinsat z is introduced, in which the electrical contact end of the contact pin on a first end portion opposite open end of the receiving portion is to be inserted.

In a first embodiment, the receiving portion has a particular sleeve-like cleaning and

Contacting section on, along the

Viewed insertion direction, is arranged in front of the Aufnahmeeinsat z, depending on the formation of the

Recording section at least a first cut

and / or a slit of the electrically conductive

Material at least at the cleaning and

Contacting section is arranged so that the

Cleaning and contacting section can be spread resiliently when the contact pin is inserted or inserted into the open end of the contact socket.

Thus, there is the advantage that impurities and / or oxidation layers can not get into the interior of the Aufnahmeeinsat zes and on or between the slats, but already before the Aufnahmeeinsat z or in the field of cleaning and

Contacting section can be effectively removed from the surface of a contact pin. The first cut impact and / or the slit on the sleeve-like cleaning and contacting section, which then thus the

Kontaktbuchseneingang forms for a contact pin, is further suitably designed so that the inner surface of the shell of the sleeve-like cleaning and

Contacting section with not inserted

Contact pin, ie in the initial state, is almost completely closed. A complementary to the contact socket trained contact pin can thus be cleaned when plugging the entire circumference.

Moreover finds in the cleaning and

Contacting section also a first electrical

Contact between the contact pin and the

Contact socket instead. Therefore, while the main part of the electrical contact and the current transmission is carried out via the slats or the Aufnahmeeinsat z, a spark break, for example, when unplugging the

Contact pin, notably on the cleaning and

Contacting take place. This has the advantage that the slats are protected from damage. In an alternative or supplementary embodiment of the invention of the Aufnahmeeinsat z according to the invention is rotatably movable about the longitudinal axis and with the

Aufnahmeeinsat z trained lamellae are aligned transversely or obliquely to the longitudinal axis of the contact socket.

In particular, by the use of a Aufnahmeeinsat ZES, which is rotationally movable about the longitudinal axis and has fins which are aligned transversely to the longitudinal axis, the invention has the advantage that when inserting the contact pin in the Aufnahmeeinsat z and thus in the contact socket, the Aufnahmeeinsat z is forced or offset in a rotational movement about its longitudinal axis, so that existing oxidation layers between the outer

Surface of the Aufnahmeeinsat ZES and the surface of the interior of the receiving portion are destroyed by frictional forces between these surfaces and the electrical Contact of the receiving insert in the receiving portion of the contact socket is thus significantly improved.

In another alternative or supplementary

Embodiment of the invention, the receiving insert is also rotatably movable about the longitudinal axis and the receiving portion is by bending the electric

formed of conductive material, wherein a first cutting joint of the bent electrically conductive material on

Receiving portion is formed. This first cut passes at least in a section in which the

Aufnahmeeinsat z is introduced, transversely or obliquely to

Longitudinal axis on the receiving section. By this embodiment of an inventive

Contact socket, it is thus possible to manufacture a female contact in a stamping and bending process cost and a Aufnahmeinsat z expedient already during the molding of the receiving insert, that is to integrate in this case when bending the receiving portion.

According to the invention runs in such

Embodiment of the first cut but at least in a portion in which the Aufnahmeeinsat z is introduced, transverse or oblique to the longitudinal axis, so that at this

Section in a rotational movement of the Aufnahmeeinsat ZES the risk of blocking the Aufnahmeeinsat ZES or individual slats on the cutting joint or at these forming cut or abutting edges of the curved

Absorption rate significantly reduced or completely

is prevented. As a result, consequently, also always a sliding rotational movement of the Aufnahmeeinsat ZES including the individual slats are guaranteed, even if, for example, due to a not

uniform orientation of the receiving portion in the bending process is given a supernatant or else

For example, a supernatant is given at the Aufnahmeeinsat z. The risk of solid oxide oxidation is therefore further reduced even further.

Overall, therefore, in all embodiments, the

Longevity of a contact socket according to the invention over the prior art improved and it must be neither consuming in rough application environment

Cleaning or lubrication processes for the maintenance of the

Contact socket to be performed.

The invention thus makes it possible that a contact socket can be manufactured inexpensively, in which a

unwanted oxide layer between an outer surface of a Aufnahmeeinsat zes and the interior of a

Contact bushing and / or an undesirable oxide layer between the inner surfaces of the contact socket and the surface of a contact pin is avoided, so that wear-free surfaces and a permanently low contact resistance of the contact socket according to the invention, especially with a high number of mating cycles are guaranteed.

Appropriately, the cleaning and

Contacting section at least one further, second cut or a further slit of the electrical material, the substantially along the longitudinal axis extends through the material, so that the cleaning ^¬ and contacting section can be spread even better, preferably evenly resilient.

The spring travel of the contact socket input a

erfindungsgenäßen contact socket forming cleaning and Kontaktierungsabschnitts is preferably adjusted so that based on the smallest and largest possible

Diameter always low insertion and removal forces

can be guaranteed.

In particular, when the Aufnahmeeinsat z is made in a stamping / bending process, this is common

at least in sections, one or more crimps and / or teeth, in which case expediently the first intersection of the electrically conductive material at the receiving portion at least in a portion of the cylinder-like interior transverse or oblique to

Longitudinal axis extends, in which the Aufnahmeinsat z such a flanging and / or toothing, so that a complete blocking or striking the flange and / or the teeth, due to the already indicated above as enabled sliding rotational movement of Aufnahmeeinsat zes on the transverse first

Cutting joint, can be avoided.

In a further preferred embodiment of the invention, in particular a bent to produce the contact socket electrically conductive material, at least in a portion of the receiving portion and in particular in the region in which the Aufnahmeeinsat z is introduced, by one or more crimps and / or gears and / or comparable connections brought into appropriate form, so that two opposing abutting edges of the first SchnittStoßes are permanently securely joined together.

It is also particularly advantageous if the Aufnahmeeinsat z is introduced into a recess formed as a seat, at least partially in the interior of the

cylindrical receiving portion is arranged, wherein the Aufnahmeinsat z in the seat has an axial and / or radial clearance. This makes it possible in a simple manner that when inserting the contact pin, the entire Aufnahmeeinsat z can be moved axially or radially, so that a solid oxidation is kept low. Also, this is the lamellae opened in a simple manner, a radial clearance to contact pins with

to accommodate different diameter sizes by clamping. To provide an elastic cylinder surface of the Aufnahmeeinsat zes and with the lamellae (110)

accompanying clamping action, the lamellae with not pushed in pin, i. in the initial state, suitably a concave outer surface of the

Form Aufnahmeinsat ZES so that they rest resiliently during the entire insertion of the contact pin and can develop their clamping effect optimal.

By using a special material for the

Admission and / or compensation of the

Aufnahmeeinsatzes, in particular of its surface, for example by galvanic treatment and / or Heat treatment, the electrical contact resistance can be further improved and a high wear resistance can be achieved even with a high number of mating cycles.

It is expedient for receiving a connection conductor at the first end portion in addition a special

Connection device arranged on which a

electrical conductor is actually fixable, wherein the electrical conductor in particular either screw, by spring technology, by crimping technology and / or by a soldering or welding technique on the connection device can be fixed. Depending on the manufacturing techniques and desired

In addition, further advantages for the economic efficiency of a device according to the invention can be achieved

Contact socket arise when the first end portion and / or the receiving portion and / or the connecting device and / or the Aufnahmeeinsat z each for all or, at least in the case that the Aufnahmeeinsat z (106) is not about the longitudinal axis (L) rotationally movable is introduced into the cylinder-like interior (104), are formed integrally in the entirety.

The invention also includes connectors having at least one contact socket, which is designed according to one of the above-described embodiments, and a particular automatic manufacturing method of a contact socket, which is designed according to one of the embodiments described above. Thus, on the one hand, at least the elongate, cylinder-like receiving portion of a contact socket according to the invention can be advantageously produced in a machining production process, in which connection, subsequent to the

Production of the receiving portion, for example by turning, the Aufnahmeeinsat ZES in the cylinder-like

Interior is introduced, for example, either through the open end or through an opposite opening in the region of the first end portion.

Alternatively, at least the elongated, cylindrical receiving portion could be in a punch-and-bend process

be prepared, for example, from pre-silvered stamped and bent material, and the Aufnahmeeinsat z supplied and in the cylinder-like interior with

be integrated by the cylinder-like

Receiving portion is bent around the prefabricated receiving insert or the Aufnahmeeinsat z otherwise in a bending operation manually or automatically in the

Recording section is integrated, so that the

Aufnahmeeinsat z in the simplest manner preferably in a snug fit, especially captive, can be caught.

In a further alternative, at least the elongated, cylinder-like receiving portion could be produced in a stamping and bending process, and the receiving unit z, similar to a machining production method of the receiving portion, be introduced into the interior following the production of the receiving portion.

The invention will be described below with reference to preferred

Embodiments according to the figures la to lf each have a shaped first end portion 102 to

Connection of an electrical conductor (not shown) on which expediently as a spring clamp additionally formed connection device 200 is arranged, wherein also other types of connection devices or a direct conductor connection on the first

End portion 102, e.g. by soldering, are possible.

3a to 3f and 4a to 4f show further exemplary embodiments of a contact socket, wherein a significant difference from the embodiments according to the figures la to lf is that for connection of the electrical conductor as an additional connection device 200, a screw terminal (Figures 3a to 3f). or a terminal device 200 (FIGS. 4a to 4f) designed as a crimp terminal, in each case at the first end section 102

is arranged.

FIGS. 1 a to 1 f or 3 a to 3 f and 4 a to 4 f show that in each of these embodiments, a

Receiving portion 101 extends from the first end portion 102 which is formed substantially cylindrical and defines a longitudinal axis L.

The elongated, shaped receiving portion 101 serves for receiving and for the mechanical and electrical coupling of an electrical contact end of a contact pin complementary to the contact pin of a connector to be mated with the electrical connector.

For this purpose, the receiving portion 101 along the

Longitudinal axis L of a jacketed from the electrically conductive material, cylinder-like inner space 104, in which a substantially cylindrical Aufnahmeeinsat z 106 is formed with lamellae 110 formed thereon, in in that the electrical contact end of the contact pin is to be inserted via an open end 103 of the receiving portion 101 opposite the first end portion 102. The Aufnahmeeinsat z 106 is also in these

previously described embodiments to the longitudinal axis L rotationally movable, wherein the figures la to lc, 3a to 3c and 4a to 4c embodiments of the invention

Contact sockets 100 with a cylindrical

Aufnahmeeinsat z 106 show which lamellae 110 which are parallel to the longitudinal axis L of the electric

Contact socket 100 are aligned. FIG. 2a shows an enlarged detail X of an interior 104 of a

Receiving portion 101, e.g. The surface of such a Aufnahmeeinsat zes 106 and in particular the material of the lamellae formed thereon 110 can be specially selected for a low contact resistance and a long life and in particular also galvanically treated and / or heat treated be.

In contrast to this, FIGS. 1 d to 1f, 3d to 3f and 4d to 4f show embodiments of contact bushes 100 according to the invention in which the receptacle insert 106 is likewise rotationally movable about the longitudinal axis L, but these contact bushes 100 have a

Contact jacks 100 conventionally a first

Cutting joint of the electrically conductive material, which substantially along the longitudinal axis L of

Contact socket 100 is arranged. A first cutting impact is accordingly only in embodiments of

Contact bushes 100, the receiving section is produced in a stamping / bending process, given manufacturing reasons. According to the figures la, ld, 3a, 3d, 4a and 4d is good

recognizable that according to the invention such a first

Cutting thrust at least in one section, at the

Moreover, in embodiments shown in two sections 105 and 105 ^" , the receiving portion 101 transversely or obliquely to the longitudinal axis L extends, where the Aufnahmeeinsat z 106 is introduced, so that the

Absorbent z 106 with the lamellae formed thereon can slide over the abutting edges of the cut bump at sections 105 and 105 'without jamming or jamming. So, for example, despite one during the

Production of the receiving portion 101 of this supernatant or even in spite of a supernatant on

Aufnahmeeinsat ZES 106 this forced or offset in a rotational movement about its longitudinal axis.

It should, however, be pointed out again that only at a section or at further sections of the

Receiving portion 101, and in particular in the region of the Aufnahmeeinsat ZES 106, such a cutting edge may extend suitably transversely to the longitudinal axis. As described below, the embodiments of contact bushes according to the invention shown in FIGS. 1 a, 1 d, 3 a, 3 d, 4 a and 4 d furthermore show further optional expedient configurations. The Aufnahmeeinsat z 106 is also according to the preferred

Embodiments according to the figures la to lf and 3a to 3f and 4a to 4f integrally formed and is advantageously also produced in a stamping / bending process. To connect the abutting during shaping bending edges of Aufnahmeeinsat zes this preferably has one or more flanges. In the figures, two flanges 108 are shown, which are arranged on the upper and lower edges of the Aufnahmeeinsat zes and may alternatively be gears. Alternatively, none or a variety of any types of

Joining connections possible. Further, in particular, the figures la and lb, ld and le, 3a and 3b, 3d and 3e, 4a and 4b and 4d and 4e to

see that a first cut of the

Receiving portion 101 preferably in a portion 105 and 105 'of the cylinder-like interior transverse to the longitudinal axis 104, in which the Aufnahmeeinsat z 106, the crimping 108 and the teeth, so that a sliding transition at the sloping abutting edges easier and the risk of blocking the Aufnahmeeinsat zes is reduced. The cutting impact in a section 105 and a section 105 'preferably proceeds in opposite directions

to each other transverse to the longitudinal axis are these effects

improved again. , Furthermore, in particular in a stamping

/ Bending process manufactured receiving section 101,

expedient at least in the area of the integrated

Aufnahmeeinsat ZES 106 along the longitudinal axis L a

Section on which one or more teeth 109, e.g. three teeth as seen in Fig. La, are arranged of the electrical material, so that the

Forming permanently maintained and expedient beyond also contact the edges of the SchnittStoßes as gap-free and safe. In addition, further toothing 109 are expediently arranged in the area above and / or below the Aufnahmeeinsat zes. It should be noted that these gearing of the electrical

Material can also be effected at least partially by crimping.

Furthermore, as can be clearly seen from the detail X of FIG. expediently be arranged in a trained as a seat recess 107, which at least partially in the

Interior 104 of the cylindrical receiving portion 101 is arranged, wherein the seat 107 z 106 the Aufnahmeeinsat expediently allows an axial and / or radial clearance. The Aufnahmeeinsat z 106 can thus be easily moved axially, radially and with little effort rotating, so that the risk of solid oxide is significantly reduced. Also, the lamellae is easily opened a radial clearance to

To be able to accept pins with different diameter sizes by clamping. In addition, if the lamellae are designed to extend transversely to the longitudinal axis, a

Rotation of the Aufnahmeeinsat zes 106 alone by the

Inserting a contact pin can be effected.

As can be seen in particular the figures Figures 4b and 4c and Figures 4e and 4f, a

Aufnahmeeinsat z 106 and / or formed thereon lamellae 110 a concave, suitably elastic surface

form. When the pin is not inserted, the lamellae are consequently formed in the cylindrical interior 104 of the Aufnahmeeinsat ZES 106 into it and can bear resiliently at or after a plug-in operation of a contact pin in the contact socket on the contact pin 100.

FIGS. 5a to 6d show further alternative or supplementary embodiments of a device according to the invention

Contact socket 100, which in contrast to the

1a to 4f may also contain a Aufnahmeeinsat z 110 which is immovably fixed in the interior 104 of the contact socket. FIGS. 5a to 5c show an embodiment of a contact socket 100 according to the invention, in which again, as in FIGS. 1a to 1f, an additional connecting device 200 designed as a spring terminal is attached to the first terminal

End portion 102 is arranged (Fig. 5c).

As can be clearly seen in the plan view of Figure 5a and the side view of Figure 5b, the

Receiving portion 101 of the contact socket 100 in an alternative or supplementary modification to the above

Embodiments of a cleaning and

Contacting section 112, which along the

Einschiebrichtung one in the contact socket 100th

to be pushed in contact pin before the

Aufnahmeeinsat z 106 is arranged, wherein a first

Cutting joint of the electrically conductive material on

Cleaning and contacting portion is arranged, at least along a portion 105 ^{'' of} the cleaning and contacting portion 112, and preferably in

Substantially runs parallel along the longitudinal axis, so that he spreads this cleaning and

Kontaktierungsabschnittes 112. This can be a

Contact pin already before entering the

Aufnahmeeinsat z be at least partially cleaned and in particular a possible spark break to

Cleaning and contacting portion 112 are relocated. In addition, the cleaning and cleaning

Contacting portion of the contact socket 100 in

expedient development further, second cutting joints 111 and 111 'on the periphery of the cleaning and

Contacting portion 112 distributed and formed along the longitudinal axis L through the material therethrough. This again increases the spring and

Cleaning effect of the cleaning and

Contacting section 112.

According to the illustrated in Figures 5a to 5c

Embodiment is the section along the portion 105 ^'' running cut an extension of the through the

Sections 105 and 105 'extending SchnittStoßes, which is not mandatory.

FIGS. 6a to 6d show a further embodiment of a contact bush 100 according to the invention which is shown in FIGS

Difference to the contact bushing 100 according to the figures 5a to 5c additionally designed as a screw terminal

Having connecting device. FIG. 6d shows a view viewed from the open end 103 on the plan view (FIG. 6a). Evident are in the subregion 105 ^'' extending

Cutting joint, arranged in the interior 104 of the female contact 100 louvers 110 and four other, distributed on the circumference of the cleaning and contacting section 112 arranged cutting joints 111, 111 ', 111' ', 111' '', so that a particularly uniform spring and cleaning effect a contact pin is achieved. The spring travel of the contact socket input one

erfindungsgenäßen contact socket forming cleaning and contacting section, such as in the figures 5a to 6d shown, is preferably adjusted so that always low insertion and removal forces can be ensured based on the smallest and largest possible diameter. An additional clamping ring around the cleaning and

Contacting section is not necessary here.

To ensure correspondingly low insertion and removal forces has in practice a spring travel as

expedient, which allows a diameter variation of about 0.15 to 0.2 millimeters. For example, if a nominal diameter of a contact pin to be inserted of e.g. six millimeters, in practice, has a diameter of the cleaning and

Contacting section with not inserted

Contact pin, which then defined above

Initial state forms, of about 5, 93 millimeters proved to be useful.

Since due to the cleaning and

Contacting section impurities and / or

Oxidation layers not in the interior of the

Aufnahmeeinsat ZES and can get on or between the slats, but already before the Aufnahmeeinsat z or in the field of cleaning and

Kontaktierungsabschnitts can be effectively removed from the surface of a contact pin, and in particular a spark break, for example, when unplugging the

Contact pin, notably on the cleaning and

Contacting takes place, the blades or the Aufnahmeeinsat z are protected in a section of

Integrated contact socket, which when inserting a contact pins the cleaning and Kontaktierungsabschnitts is downstream. The slats are thus protected from damage.

As can be seen in addition to FIGS. 5b and 6b, the dimensioning of the inner diameter of the cleaning ^¬ and contacting section and the dimensioning of Aufnahmeeinsat zes can be coordinated so that the Aufnahmeeinsat z hereby loss-safe inside

Contact socket is integrated.

The contact socket according to the invention can be arranged as part of a connector, in particular as a single contact in a contact insert block of a connector. Since such connectors and contact insert blocks the

Professional are known per se, was waived a corresponding figurative representation.
