Definitions

• the invention relates to a flat receptacle for electrically contacting receiving a flat plug according to the preamble of claim 1.
• Such electrical plug connections are usually relatively inexpensive to manufacture and can often be assembled by simply pressing them with the appropriate cable sets. The assembly can also be done manually with relatively simple means and hand tools, if this becomes necessary in the workshop, for example.
• relatively high currents can be transmitted via flat plug connections, which plays an important role in the low-voltage electrical system of the motor vehicle.
• Generic flat sockets are also often used to Both fuses and relays on printed circuit boards are to be contacted electrically as well as mechanically.
• Flat plug connectors are known for applications with particularly high requirements with regard to transferable current strength, mechanical strength, vibration resistance and robustness in workshop operation, the socket shaft of which comprises a contact spring basket or lamella basket.
• a socket well designed in this way has the advantage that, on the one hand, a relatively firm hold of the contact knife in the flat plug socket and, on the other hand, a relatively high current strength can be transmitted due to the increase in the number of electrical contact points between socket and plug.
• these known flat plug connections also have a certain self-cleaning effect of the electrical contacts, which comes into play each time the electrical contact is released or added.
• the object of the present invention to provide a flat plug socket for an electrical flat plug connection which overcomes the disadvantages of the prior art described.
• the electrical flat plug connection should combine particularly high mechanical safety and electrical transmission security with a high maximum current carrying capacity.
• the tab receptacle comprises, in a manner known per se, a receptacle shaft for receiving and electrically contacting a tab connector or contact knife, the receptacle shaft having at least one comb-like array of essentially parallel contact webs running in the plugging direction and arranged on at least one broad side of the receptacle , In a manner which is also known per se, the contact webs have a course curved towards the center of the socket shaft.
• the flat receptacle is distinguished in that the curvature of the section of the contact webs bent toward the center of the shaft has more than one apex in the region of the contact zone with the flat plug.
• each of the webs from the web share of the socket well does not, as in the prior art, have only one apex and thus only one contact point with the flat plug or with the contact knife, but rather several, preferably, per web two, contact points or contact zones for the transmission of electrical current are available.
• This is also advantageous insofar as in this way higher mechanical clamping forces between the flat plug socket and the flat plug or contact knife can be achieved, which is conducive to both the mechanical and the electrical safety of the plug connection.
• the higher clamping forces are achieved without the necessary insertion forces being necessary increase to the same extent.
• the contact knives for example two vertices, do not have to be overcome by the contact knife at the same time, but rather can be successively overcome one after the other.
• the force-displacement curve is smoothed when the contact knife is inserted into the socket shaft, which considerably simplifies the manual connection.
• the flat receptacle is characterized by soldering legs or press-in pins for electrically contacting mounting of the flat receptacle, in particular on a printed circuit board.
• the soldering legs or press-in pins are arranged in an extension of at least one of the two broad sides of the flat receptacle.
• the soldering legs or press-in pins are particularly preferably formed in one piece with the respective broad side of the flat receptacle.
• crimp bars can also be used for the electrically contacting assembly of the flat plug socket. This is particularly suitable for contacting at one end of the cable.
• the flat receptacle is a one-piece stamped and bent part educated.
• the stamped and bent part is bent perpendicular to the plug direction of the plug connection between the flat socket and the flat plug to form a rectangular box profile.
• This embodiment has the particular advantage that it can be manufactured extremely inexpensively and efficiently.
• the flat plug socket is particularly robust and stable.
• the closure of the rectangular box profile of the flat receptacle is formed by a form-fitting pairing of at least one notch and at least one tab.
• the notch has an undercut, and the tab is designed to match the notch.
• the form-fitting pairing of notch and tab is arranged on a narrow side of the socket well, or the pairing of notch and tab is additionally non-positively stamped after the joining. Both lead to a particularly high stiffness, in particular torsional stiffness and bending stiffness, of the box profile of the flat receptacle.
• the flat receptacle comprises at least one support spring arranged on the end face of the socket well.
• the support spring forms a further mechanical and / or electrical contact zone between the flat plug socket and the flat plug. This results in an even higher nominal current that can be transmitted by means of the plug connection, better guidance of the contact blade when the plug connection is being made, and greater security against unintentional removal of the contact blade from the flat plug socket.
• the at least one support spring is particularly preferably also integrally formed on a narrow side of the socket shaft, which can be done, for example, by notching when punching the sheet metal material of the socket shaft.
• the socket well has, in addition to the contact webs running between the ends of the jack shaft, axially extending stabilization webs. These stabilizing webs connect the two axial ends of the socket well firmly and at an invariable distance.
• Stabilizing bars no change in length of the socket shaft can take place when inserting the contact knife.
• the stabilizing webs prevent deformation of the socket well, which could otherwise occur in particular if the plug is inserted incorrectly or if the contact blade is not inserted coaxially.
• the stabilizing webs prevent bending forces from being transferred to the soldering points between the flat receptacle and the printed circuit board, since the stabilizing webs ensure the shape of the socket well and thus the constant distance and angle of the soldering legs.
• the stabilizing webs also enable even higher contact forces to be achieved between the contact webs and the contact knife, in particular since the stabilizing webs reliably prevent axial changes in the length of the socket due to the deformation of the contact webs when the contact knife is inserted.
• the stabilizing webs are preferably formed by the longitudinal edges of the rectangular box profile. This is advantageous because of this Optimal use of space in the area of the socket shaft takes place. In addition, a socket shaft with maximum bending strength and maximum torsional strength is obtained.
• the flat receptacle according to the invention can in principle be manufactured from a wide variety of conductive materials. According to a preferred embodiment of the invention, however, the flat receptacle is made of highly conductive material which at the same time has a particularly high specific elasticity. In this way, high nominal currents can be transmitted, and there is also a high level of security against mechanical overloading of the plug connection.
