Definitions
- the invention relates to an electrical connector according to the preamble of claim 1.
- Electrical connectors are used to make electrical contacts between an electrical device or a printed circuit board (such as a PCB, Printed Circuit Board) and an external connection means, such as a plug.
- the connector is often associated with a plurality of electrical connections forming pins.
- About each pin of the connector is a single contact on the circuit board can be controlled by a conductor.
- pins of the connectors are very susceptible to vibrations and extreme temperatures. For example, in equipment subject to increased vibration, a pin in the connector and triggers a faulty contact or short circuit in the connector. A similar risk exists at high or low temperatures. Due to local stresses of the material, individual pins in the connector can be solved, which in addition to the above-mentioned disadvantage, moisture and dirt can penetrate into the connector.
- the invention has for its object to provide an electrical connector that is easy to manufacture and very robust against mechanical and thermal environmental influences.
- an electrical connector for solving this problem has the features of claim 1. Accordingly, it is provided that in the electrical connector according to the invention in a connector part a plurality of pins is arranged, wherein the pins are electrically connectable by a respective conductor with contacts of a contact strip, which is arranged in particular in a housing. According to the invention, at least one conductor is arranged in a stamped grid and the stamped grid is fixedly arranged in a holder. This arrangement of the at least one conductor having stamped grid in a holder, the conductor arrangement designed as very compact and robust. Mechanical vibrations on the conductor are absorbed by the holder. From a production point of view, the holder can also be referred to as a semi-finished product.
- a further possible embodiment of the invention may provide that the at least one stamped grid is firmly cast in the holder, preferably encapsulated, in particular the stamped grid is mounted in the holder prior to casting or encapsulation.
- the holder can thus form a frame-like body or cuboid by the conductors are arranged. This pouring of the stamped grid is a very compact and easy to handle arrangement of the ladder. After the conductors are embedded in the holder, a punch bridge of the stamped grid connecting the pins and / or the conductors can be removed.
- the present invention may further provide that at least one pin and / or at least one conductor and / or at least one contact are formed from the at least one stamped grid, in particular in each case a pin with a conductor and a contact are formed integrally from the at least one stamped grid.
- a one-piece conductor piece consisting of a pin, a conductor and a contact punched out of the stamped grid and arranged in the holder. It can be inventively provided that the pins are firmly connected to the holder, in particular cast or injected into the holder. By this one-piece piece of the conductor piece and the embedding in the holder, the production of the connector designed as extremely simple.
- the invention provides that a plurality of leadframes, each having juxtaposed pins and conductors and contacts arranged in the holder one above the other, in particular cast or molded, are to form a plurality of rows of pins and conductors and contacts. It is also conceivable that an arbitrary arrangement of the pins can be realized by the stamped grid. If the individual stamped grids are arranged one above the other, they each have a sufficiently large distance between them, so that the pins or the lines or the contacts do not interfere with one another or no breakdowns occur.
- the present invention can further provide that the holder can be connected to the at least one stamped grid with the connection part and / or the housing, in particular with the connection part and / or the housing can be brought into a latching connection, preferably with the connection part and / or castable to the housing, in particular can be sprayed or glued.
- the holder is the punched grid or with the dedicated pins, the conductors and the contacts an integral part, which is fauxbringbar when assembling the connector with the other parts.
- the holder having the pins can be plugged together with the connection part of the connector.
- a further alternative embodiment may provide that the holder is inserted into the housing of an electrical device or through the housing into the connection part. Due to the fixed assignment of the pins to the holder, the pin arrangement designed as very compact and easy to handle.
- the present invention may further provide that the contact strip is associated with the stamped grid decoupled from the housing and / or the connecting part, in particular that the contact strip is associated with a printed circuit board or a printed circuit board. By decoupling the contact strip from the housing or from the connection part, all mechanical impacts or vibrations are decoupled from the contact strip. Thus, by decoupling the contact strip from the housing and / or the connection part, a mechanical resistance to vibrations can be created.
- the printed circuit board can alternatively also be any circuit of an electrical device having any contacts.
- the contacts or the lead frame at least partially cast in the contact strip, in particular encapsulated or stamped or pressed or welded. This creates a continuous, constant connection between the contact strip and the pins.
- This one-piece design of the pins, the conductors and the contacts makes the connector or the contacting extremely robust.
- the type of connection between the conductor and the pin or the contact is determined by the material of the components or the method of manufacture. Furthermore, the type of contact can change according to the requirements of the electrical connector.
- the stamped grid in the region of the ladder in each case has a strain relief, in particular the strain reliefs are shaped meander-shaped, preferably that the strain reliefs are punched out of the stamped grid in a meandering manner.
- This meandering strain relief is a kind of spring element which can compensate or cushion relative movements between the pin and the contact or between the semifinished product and the contact strip.
- This meandering configuration of the conductors and their attachment in the holder or on the contact strip lead to a robust electrical connection in the connector.
- the invention can provide that the meander-shaped strain reliefs are aligned parallel to a punch plane of the stamped grid.
- the conductors of a stamped grid are arranged parallel to one another between the pins and the contacts, in particular that the strain relief are arranged parallel to one another.
- the parallel arrangement of the conductors is advantageous insofar as thus a contacting of the individual conductors is avoided. Since the ends of all conductors are in the holder or on the common rigid contact strip, the conductors move in a relative movement between the holder and contact strip alike. The formation of a short circuit by at least short-term contact of conductors can thus be avoided. It is according to the invention, however, also conceivable that the conductors are not parallel, in particular arbitrarily to each other, are arranged.
- the invention can further provide that the stamped grid is bent at the transitions from the pins to the conductors and from the conductors to the contacts, in particular in each case has deflections from the punching plane. Due to these deflections, the pins or the conductors which are assigned to the different stamped gratings arranged one above the other can be brought to the same level of the contact strip. Depending on the positioning of the individual stamped grid in the holder, the deflection is different strong. For the punched grid located at the top, the deflection between pin and conductor or between conductor and contact is the strongest; whereas the deflection is lowest for stamped grid located at the bottom. The production of the deflections to the individual punched screens takes place before pouring into the holder, but can also be done after pouring into the holder.
- Fig. 2 is a sectional view through the electrical connector
- Fig. 3 is a perspective view of a holder.
- the electrical device may have an electrical connector 10.
- the illustrated in FIG. 1 electrical connector 10 is disposed in a housing 11 of an only indicated electrical device.
- the electrical connector 10 has a connection part 12. This connection part 12 extends through a wall 13 in the housing 1 1 of the electrical device.
- the pins 14 are arranged in a plurality of rows in the electrical connector 10.
- the housing-side ends of the pins 14 are each in one piece in a conductor 15 via.
- These conductors 15 each go, also in one piece, into a contact 16, which is associated with a contact strip 17. Via this contact strip 17, the electrical contact of each pin 14 with the printed circuit board 18 is produced (FIG. 1).
- the conductors 15 describe a meander-shaped strain relief 21 between the pins 14 and the contacts 16 (FIG. 3). These strain reliefs 21 run side by side for the pins 14, which are arranged in a row. As a result of the exemplary embodiment of an electrical connector 10 shown here having a plurality of rows of pins 14, a plurality of meander-shaped conductors 15 are arranged offset one above the other in parallel (FIG. 3). However, the invention is not limited to the arrangement of the pins 14 shown in FIG. 3; Rather, it is also conceivable that the connector has only a few pins 14, or a plurality in any arrangement.
- the pins 14, conductors 15 and contacts 16 form as a single, contiguous part of a stamped grid 19, ie pins 14, conductors 15 and contacts 16 are punched together from a single piece.
- a punched grid 19 each forms a series of juxtaposed pins 14, conductors 15 and contacts 16.
- the fact that the pins 14, conductors 15 and contacts 16 are made of a single, contiguous piece of material, they are integrally formed.
- three punched grid 19 are arranged one above the other.
- the contacts 16 are each in the plane of the contact strip 17, the lead frame 19, or respectively a "pin - conductor - contacts - triplet" two deflections 22. These deflections 22 describe a deflection out of a punch plane (FIG. 3).
- the deflections 22 of the conductors fall
- the punched grid 19, or the pins 14, conductors 15 and contacts 16 are electrically isolated from each other a holder 20 fixedly assigned (Fig. 3).
- the holder 20 forms a rectangular receptacle and is at least partially around the stamped grid
- the at least one stamped grid 19 or around the pins 14 and / or the conductors 15 are poured or sprayed, preferably after the stamped grid 19 has been mounted in the holder 20.
- This will usually use a plastic. It can therefore be provided that the at least one stamped grid 19 is first mounted in the holder 20 and thereafter encapsulated with, for example, a plastic or molded around.
- the contacts 16 are cast into the contact strip 17, injected, stamped, pressed or welded. As a result of this firm connection of the contacts 16 into the contact strip 17 or the pins 14 in the holder 20 and through the meander-shaped configuration of the conductors 15, the present invention produces a robust and resistant connection between a connection means and a printed circuit board 18.
- connection part 12 For this purpose, the holder 20 and / or the connecting part 12, for example, have latching elements.
- the holder 20 can therefore also be referred to as a semi-finished product.

- the holder 20 is encapsulated with the connection part 12.
- the contact strip 17 contacted by the contacts 16 is assigned to the printed circuit board 18 from the connection part 12 or from the housing 1 1, respectively.
- the contact strip 17 can for example be screwed onto the circuit board 18 or clamped or glued.
- a further embodiment may provide that the connecting part 12 is placed from the outside against the wall 13 and the holder 20 is pushed together with the pins 14 and the conductor 15 from the interior of the housing 11 through the wall 13 in the connection part 12 and optionally shed , In this way, the electrical connector 10 can be firmly connected to the electrical device or the housing 1 1.
