Definitions

  • the invention relates to an electrical connector with the features of the preamble of claim 1.
  • both the printed circuit board and an electrical conductor are electrically connected by means of plug-in assembly to the contact spring lying in the insulating housing of the connector.
  • both the circuit board-connector connection and the connector-conductor connection are realized by a direct plug connection.
  • a disadvantage of the known connector is the complex design of the contact spring.
  • connection end causes the metal sleeve to be pressurized when the conductor is inserted. The connection end then returns to its starting position and engages behind the metal sleeve for locking the conductor in the insulating housing.
  • the invention has for its object to simplify the plug-in assembly of a connector of the type mentioned and to improve its operational safety. This object is achieved by the combination of features of claim 1.
  • connection end of the contact spring acts directly on the conductor inserted into the insulating housing with spring force for the electrical connection and at the same time for the clamp fixation of the conductor on the plug connector. Due to their spring elasticity, the connection end adapts to different outer contours of the conductor or the conductor end, without any loss of electrical connection reliability of the conductor in the insulating housing of the connector. Different types of conductors can therefore be connected to the connector at the connector according to the invention by a simple plug-in process. This supports the universal applicability of the connector according to the invention. For example, the stripped conductor end of a conventional conductor can also be connected to the connector.
  • connection end can be preprogrammed to a certain extent by appropriate processing of the contact spring and / or by the spring constant of the selected spring material.
  • connection end of the contact spring can be adapted even better to different conductor cross sections. According to the invention, it is therefore possible, without any design changes to the insulating housing, that contact springs of identical design have connection ends with different spring force if conductors with different line cross sections are to be connected to a multipole connector.
  • connection end is designed in the manner of a barb and additionally acts on the conductor with a holding force which is effective approximately in the insertion direction and which prevents the conductor from being pulled out of the insulating housing of the plug connector in an undesired manner.
  • this barb is technically simply formed by an angled portion of the contact spring, whereby the connection end is also constructed to save space.
  • the conductor automatically bends the connection end against the spring force when it is inserted into the insulating housing. When the conductor is fully inserted, the connection end also springs back automatically and clamps the conductor with its spring force.
  • the contact spring is slotted longitudinally at the connection end, so that two mutually independent conductors can be connected to the same contact spring per connection pole.
  • the conductors have a small cross section, e.g. is the case in telecommunications.
  • two conductors with the same pole can advantageously be mechanically and electrically connected.
  • connection end is limited during the manufacture or release of the clamp fixation. This ensures that the connection end acted upon from the outside by the inserted conductor or an assembly tool has a constant spring force over a long operating time.
  • the measure according to claim 5 supports the mechanically stable support of the externally loaded and thereby pivoted connection end on the stop tab.
  • Claims 6 and 7 enable a mechanically reliable hold and fit of the plug connector, in particular that plugged onto a printed circuit board Connector. According to claim 7, the mechanical and electrical contact pressure of the contact spring on an electrical contact point, in particular on the contact field of a printed circuit board, is further improved.
  • Claim 8 supports the positional securing of the entire contact spring within the insulating housing of the connector.
  • the contact spring is simply inserted into the insulating housing from an assembly point of view and automatically engages there.
  • a catch element which is preferably connected in one piece to the contact spring and which interacts with a fixing lug formed in the insulating housing, serves as the locking means. This prevents the contact spring from being accidentally pulled out of the insulating housing against the direction of insertion.
  • a deliberate release of the latched contact spring can be provided by means of suitable measures and / or by means of assembly tools which engage in the insulating housing.
  • the rear engagement part for securing the position of the contact spring is arranged in a mechanically stable and space-saving manner on the spring base body of the contact spring.
  • Claim 10 supports the manufacture and use of the contact spring as an inexpensive mass article.
  • Claim 11 favors a space-saving structure of the contact spring. This advantageously further miniaturizes the entire connector.
  • Claim 12 favors the division of the contact spring into two mutually independent lever arms.
  • the circuit board and the conductor can therefore advantageously be electrically contacted independently of one another with the contact spring, without there being any impairments in the clamping fixation or the electrical contacting by the respective other lever arm.
  • the measure according to claim 13 makes it easier for the fitter to insert a conductor into the connector in accordance with the assembly.
  • the measure according to claim 14 creates a continuous development of the plug-in assembly of the connector.
  • one or more latching hooks are arranged on the insulating housing, which latch in a springy manner. In cooperation with a circuit board, these latching hooks engage in corresponding locking openings in the circuit board. In this way, the connector on the circuit board is securely locked and further stabilized against unwanted changes in position.
  • the contact spring itself accomplishes the clamping fixation or plug-in assembly of a conductor and an element to be contacted. Since the contact spring is made of electrically conductive metal, it has consistently good thermal and mechanical properties over a long period of operation. As a result, standardization requirements for the clamp fixation or plug-in assembly can be easily met. In addition, due to the elimination of thermal / mechanical loads, the insulating housing can be produced from a comparatively inferior and therefore inexpensive insulating plastic.
  • the connector can be inserted in different relative positions, in particular both horizontally and vertically. This allows the connector to be space-savingly adapted to different space conditions or required relative positions.
  • Claim 18 proposes a particularly simple and mechanically stable plug connection between the contact spring and an element to be contacted.
  • This element is in particular a contact pin of the printed circuit board, which can be positioned differently on the printed circuit board.
  • This " indirect" plug-in assembly between contact spring and printed circuit board results compared to plugging the connector directly onto the edge of the PCB ( direct “plug-in assembly) more variable positioning options for the connector on the circuit board.
  • Claim 19 additionally stabilizes the plug-in assembly.
  • the diametrical slot allows the tulip contact to be adapted in the manner of a spring contact to differently dimensioned contact pins or elements to be contacted.
  • Claim 20 creates a particularly stable configuration of the contact spring, the components projecting beyond the spring base body being an integral part of the contact spring.
  • Claim 23 proposes a stable metal abutment for the spring leg-like connection end. This improves the clamping force exerted on the connected conductor.
  • the measure according to claim 24 makes it easier for the fitter to insert a conductor into the connector in accordance with the assembly.
  • each pole of the connector is preferably identical, so that structurally identical contact springs can also be used in the insulating housing.
  • the number of components to be stored for the implementation of all embodiments of the connector therefore remains low. Due to the identical design of the connection poles of the insulating housing, similar molds can be used for the cost-effective production of the plug connectors.
  • the multi-pin connector is a more compact and mechanically stable unit. At the same time, even on a multi-pole connector with a large number of poles, the connection of many conductors remains clear and easy to install.
  • the electrical connector 1 has an insulating housing 2 and, depending on the number of poles, one or more contact springs 3 arranged in the insulating housing 2 (FIG. 1, FIG. 2). 5, the plug connector 1 is plugged onto a printed circuit board 5 in the plugging direction 4 and provided with an inserted conductor 11.
  • the circuit board 5 contains a plurality of conductor tracks 6, each of which is assigned an electrical contact field 7 at the end.
  • a contact end 8 of the contact spring 3 is under mechanical prestress, i.e. under spring tension on a contact field 7 of the printed circuit board 5 (FIG. 5).
  • the electrical connection between the contact spring 3 and the associated conductor track 6 is established by the bias.
  • the contact spring 3 has a connection end 10 facing away from the contact end 8 in the spring longitudinal direction 9. (Fig.5).
  • the connection end 10 can be electrically connected to a conductor 11 assigned to the contact spring 3.
  • the connection end 10 acts directly on the conductor 11 with spring force. In this way, the electrical connection and at the same time a clamping fixation of the conductor 11 to the connector 1 is realized. 5 that the connection end 10 presses the conductor 11 or its stripped conductor end 12 directly against an inner wall of the insulating housing 2. This provides a good mechanical hold for the stripped end 12 in the insulating housing 2.
  • connection end 10 acts upon the conductor 11, which is inserted into the insulating housing 2 in the insertion direction 13, in the manner of a barb. This barb prevents undesired removal of the conductor 11 against the insertion direction 13.
  • the terminal end 10 is directed as an end section with the contact spring 3 towards the spring base body 15, i.e. bent in the bending direction 15 (Fig. 7).
  • the connection end 10 and the spring base body 14 form an acute angle ⁇ of approximately 40 ° -60 °.
  • connection end 10 In the assembled state of the contact spring 3, the conductor end 12 inserted into the insulating housing 2 is clamped by the free end 16 of the connection end 10 which points approximately in the direction of insertion 13, as a result of which the barb effect of the connection end 10 is produced.
  • connection end 10 has a longitudinal slot 17 running in the longitudinal direction 9 of the spring. This longitudinal slot 17 extends from the free end 16 approximately to the arcuate bending point 18 of the connection end 10. Through the longitudinal slot 17, the connection end 10 is divided in two in the transverse direction 19 arranged at right angles to the spring longitudinal direction 9 to form two connection contacts 20, 21 for each conductor 11.

  • the fixing tab 30 is located in the space between the fixing lug 29 and the lever lug 26, which acts as a locking shaft 46.
  • the locking shaft 46 is accessible to a fitter with the aid of a special tool. In this way, the fixing tab 30 can be acted upon and the locking of the contact spring 3 can thereby be released. In the event of maintenance or repairs, the contact spring 3 is therefore easy to replace.
