Electrical connector

description

The present invention relates to the field of electrical connection technology.

Currently plug, terminal points, such as terminal blocks, device connections and all known electrical connections by a mechanical locking of a cable and an electrical contacting of a conductor by means of screw, spring or

Cutting connections realized. Furthermore, electrically conductive metal may be incorporated in a connector e.g. can be replaced by a metal applied by means of the MID (Molded Interconnect Device) technology, which reduces the number of connector components. In addition, via the connectors electrical conductors can be connected using a socket and a plug. Here, the electrical connection is made via a resilient contact, wherein a housing is provided to ensure the tightness of the plug. However, known electrical connectors are complex because they often consist of a plurality of different components.

It is the object of the invention to provide a simple electrical connector. This object is solved by the features of the independent claim. Advantageous developments are given in the dependent claims.

The invention is based on the recognition that a simple electrical connector, for example a plug connector or a terminal, can be realized using at least two plastic sections, wherein at least one of the plastic sections is elastic and, for example, reversibly deformable and wherein the other plastic section is for example shaping.

Thus, an integration density and handling of a connection by means of a plug, by means of a detachable

Contact or by means of a fixed electrical connection can be significantly changed, all components of such a compound are considered according to the invention. This concerns for example a contact to the conductor, a ^■ locking of a cable, the forwarding of the contacted signal, for example in the form of a current or a voltage into account a shield connection or a kink protector, a locking of the plug and the socket, a sealing of the plug, the Socket and the cable as well as the handling of these elements.

By using the elastic plastic section mechanical springs can be replaced, since a combination of a flexible plastic section to

Contacting a conductor or mating connector with a clamping body without an additional mechanical use of spring elements or clamping parts due to the use of soft or elastic plastic sections in combination with shaping hard plastic sections is used. The combination of flexible plastic sections and mechanically harder sections of fabric serves not only the mechanical stability but also the solubility of the connection. The different degrees of hardness or elasticity of the plastic sections can be based on different plastics used and / or on different geometries and shapes of the sections, even with the same plastics included. In the following, the term "soft plastic" is used to designate a plastic section that has a lower degree of hardness than a "hard plastic section", and vice versa.

According to a further embodiment of the invention, the plastic sections may be conductive and used in a connection point. For example, the plastic surfaces are conductive. The contacting of electrical conductors can for example be replaced by a soft embedded plastic with a conductive material or with a conductive substrate with eg metals applied thereto or with galvanized plastic or conductive plastics, which is also possible with the less elastic, harder plastic with a conductive surface is. This combination is especially advantageous for the further miniaturization of the clamping body. For example, by a conductive plastic, which is produced for example by means of the so-called nano-tubes, the contact with the conductor are formed over a large area, since a contact surface corresponds to the entire conductor end, the lock can be made by a separate locking technology. The design of the clamp and the terminal design can thus be more flexible. According to the invention, it is possible to inexpensively and efficiently spray down complex compact structures and connectors or to make them mechanically simple. The inventive concept enables a higher complexity in the

Clamping mechanism, because more moving and smaller parts are possible, but does not contain the disadvantage of the composition of many components. The mechanism can be created, for example, as a composite by a placing function injection molded part, which is surrounded in a further injection process with softer plastic and thus functionally assembled. As a result, easier handling of the products for electrical and mechanical contacting of conductors and cables is achieved. The inventive concept also makes it possible to manufacture new types of connectors and contacts, such as board connectors, or to develop alternative connection methods. The function of the electrical connector is simplified by the mechanically coherent design of the plastic sections with elastic, soft plastic. The feel is improved by the design with soft or with molding plastics. This not only applies to the handling of the controls, but also to the support of functions, such as the

Reduction of slipping out of inserted cables or two paired connectors. The concept also allows a simple and complex mechanical structure creation by, for example, the injection molding process. Moreover, it is possible to realize the electrical connector completely without metal components. For example, the elastic, soft plastics can be made using plastic softeners.

The beads 1705 can be shaped, for example, in the form of latching lugs, as shown in FIG. 17. Here, the so-called forming effect is exploited.

Fig. 18 illustrates the assignment of the by the

Plastic sections embodied properties of the respective functionality of the electrical connector according to the invention.

Fig. 19 shows an electrical connector having a first portion 1901 in the form of a solid plastic plug, a resilient second portion 1903, and a plug contact 1905 formed, for example, as a metal contact with the conductor 1907 and as a spring element for locking.

Plastic portions 2501 in the form of tooth-like clamps, which are pivotally connected about a Verschwenkungsort a connector body 2503 with this connector body 2503 -sind. For this purpose, a softer plastic portion 2507 in the form of an O-ring is guided around the connecting body 2503, which rests firmly on the clamps 2501 near a pivoting location of the connector body 2503. Upon pivoting of the clamps, the O-ring 2507 traverses the pivot location of the connector body 2503 so that the clamps are releasably fixed in either an open, receptive position (Figure 25a) or a closed position (Figure 25c). When inserting a mating connector 2505 with an outer configuration at least partially correspondingly complementary to the tooth-like clamps, the tooth-shaped sections illustrated in FIG. 25 intermesh to form the connection illustrated in FIG. 25c.

Fig. 26b shows the conductor of Fig. 26a in cross-section. Fig. 27 illustrates the operation of the connectors shown in Figures 25 and 26, which operate on the O-ring effect or frog effect.

Figures 28a and b show possible states of terminal shapes by utilizing the stocking effect already described. Using elastic portions 2801 and less elastic portions 2803, a pivotal lever mechanism is realized. Between the lever arms defining portions 2803 another deformable plastic portion 2805 is held, which defines a receiving space in which a contact conductor is arranged. As shown in Fig. 28a, a conductor 2807 is inserted from the side of the lever mechanism into the opened receiving space of the deformable plastic portion 2805. By pivoting (Fig. 28b) at least one lever arm in the opposite direction to the direction of insertion of the conductor 2807, the plastic portion 2805 is compressed, the receiving space closed and the conductor 2807 clamped on the contact conductor. In this state, the conductor 2807 remains trapped on it even when pulling. An additional introduction of harder plastic in the deformable plastic portion 2805 can the holding effect

Fig. 29 shows a further terminal form, for example in the form of a large clamp, which can be molded from one piece, schematically from the front or rear, so that a knitting element acts in common on all terminal points. Alternatively, a single active element can also be formed for each clamping point.

FIG. 30 shows a schematic side view of a clamp / active element similar to FIG. 29 with a first section 3001, a second section 3003 and a third section 3005. The sections 3001 and 3005 are less elastic than the section 3003 and consist for example of hard plastic. They can also be manufactured in the MID technology or partially made of metal. To open the clamp, for example, a pair of pliers can be used, wherein a conductor 3009 is introduced, for example via a rocker effect. The more elastic plastic portion 1503 is thus similar to that described with reference to FIGS. 15 in turn preferably arranged in such a way between the sections 3001 and 3005, in order to enable the rocker effect. In principle, to insert and clamp a conductor 3009 utilizing the seesawing effect, a pin-type tool 3007, such as that shown in FIG. a screwdriver 3007, which is used in one of the two attack positions shown in Fig. 30.

FIG. 31 schematically shows further terminal shapes, wherein, in order to receive a conductor 3101, for example, a latching mechanism 3102 formed of harder plastic sections is supported between softer plastic sections 3103. A rasterization can also be generated, for example, as a mechanical cam mechanism, wherein a rocker mechanism for clamping a conductor 3104 can also be used.

In Fig. 32, two more terminal shapes are shown. The left side view in FIG. 32 shows a male conductor 3201 to be electrically connected to a conductive contact portion 3202 disposed in the connector is. In this case, a detent mechanism 3203 formed of harder plastic sections is supported only on one side on a softer plastic section 3204 which has to be pressed in the opposite direction for releasing. On the side opposite the softer plastic section 3204, a substantially harder contact or support section 3205 is arranged.

32 shows a terminal shape in which a male conductor 3201 to be electrically connected to a conductive contact portion 3202 disposed in the connector is clamped at the pad by a harder plastic portion 3207 around a softer plastic portion 3206 by means of a plastic pin-like tool or actuator is pivoted in the direction of the conductor 3201 and the receiving opening is closed by pressure of the softer plastic portion 3206 by means of a harder plastic portion 3207. The screening of the hard plastic section 3207 engages in the screening of the surrounded hard plastic housing. The latching is similar to the operating principle of the left-hand illustration in FIG. 32, wherein the movement here is not linear but takes place on a circular path. To open the pen-like tool is moved in the opposite direction. Further, to release the conductor 3201, depending on the strength requirement of the locking, a second e.g. wedge-shaped harder section 3208 with a tool to be applied, the grid between housing and harder plastic section 3207 move apart.

FIGS. 33 and 34 show further terminal shapes.

In Fig. 33, the arrangement of the plastic portions of the terminal mold is such that a softer plastic portion 3301 is pivoted about an off-center pivot axis 3302 for opening or closing to press an inserted conductor 3303 in the closed state against a connector conductor 3304 arranged in the connector. The pivotable plastic portion 3301 is further supported against a harder plastic portion 3305, which also provides in the illustrated arrangement, a safeguard against accidental withdrawal of the conductor 3303.

In Fig. 34, the arrangement of the plastic portions of the terminal mold is such that a harder plastic portion 3401 presses an inserted conductor 3403 in the closed state against a contact conductor 3404 disposed in the connector. The plastic portion 3401 is arranged on a softer plastic portion 3402 such that it is compressed by the use of a pin-like tool for opening and springs back automatically with the tool removed, thus providing an automatic closing of the insertion opening.

FIG. 35 shows a terminal form having a first portion 3501, a second portion 3503 disposed on a third portion 3505. Furthermore, a section 3507 is provided. The portions 3501, 3505 and 3507 are less elastic than the portion 3503. The opening of the terminal for clamping a male conductor 3509 between the two harder sections 3501 and 3505 is again made using a pin-like tool, the state transition in Figs. 35a and 35b is shown. In the illustrated in Fig. 35

Clamp the frog effect is exploited, the consequence of the sections 3505 and 3507 connecting more elastic portion 3503, by means of which the two harder sections 3505 and 3507 against each other and locked in the state shown in FIG. 35b releasably locked can. The reverse attachment of the device (release and closing direction swapped) would make it difficult to pull out.

Fig. 36 shows a clamp with a first portion 3601, which is formed for example of hard plastic, and a movable second hard plastic portion 3603, which may for example comprise elastic plastic parts 3605. The clamp shown in Fig. 36 may be made, for example, by a screwing in the manufacture to make a plug, or by overmolding to make a terminal. In Figs. 36a, 36b and 36c, for example, the closing operation using a pen-type actuator is made from an open position without inserted conductor 3609, via an open position in which a picked-up conductor 3609 is contacted by a cutting profile 3607 toward a closed position in which the conductor is clamped between the harder sections 3601 and 3603. It can be a

Fig. 36d shows another view of such a clamp, wherein HK is called hard plastic. The section 3611 as well as the insulation displacement elements may further be made, for example, of metal or in MID technology.

Fig. 37 shows an electrical connector which is opened using a pin as in Figs. 37a and b.

Fig. 38 shows another terminal shape using soft plastic as a hard plastic material with a thinner material. The clamp is with a printed circuit board 3801, wherein a termination 3803 of a arranged in the clamp conductive contact, for example, using the MID technology, made of metal or conductive plastic can be made. The triggering is effected by the resilient hard plastic 3805, wherein the pressure by a screw 3807, which can be formed in the front region as non-cutting and thus better pressing and, for example, can have longitudinal grooves for fixing, can take place. A conductor 3809 inserted into the terminal can thus be securely locked and pressed against the contact arranged in the terminal.

Fig. 39 shows another terminal form in which a ferrule 3901 can be used as, for example, a part of the terminal. Further, various are

Plastic sections 3903, 3905 and 3907 are provided, wherein a conductor 3909 is locked via a toothing of the sections 3905 and 3907.

Fig. 40 shows other Kletnmenformen in which the so-called assistant effect is exploited. The clamp comprises a soft plastic 4001, which may for example be provided with stabilizers 4003, which may be made of, for example, a harder plastic, wherein a line piece 4005 as shown in Figures 40c and 40d is inserted and locked. In this case, components made of hard plastic 4007 are provided, further comprising a comb-shaped portion 4009, which may consist of an elastic plastic or of a harder plastic.

The inventive concept makes it possible to manufacture the electrical connector, which may be designed, for example, as a clamp, automated in the plastic injection molding process, wherein for the introduction of Metals, screws or different plastics per se known manufacturing method can be used.
