Definitions

  • the invention relates to a contact spring for an electrically contactable component and has an electrical connection for a conductor.
  • Such a contact spring is known from GB-A-2 049 307.
  • the contact spring is installed in an insulating housing and clamps a conductor inserted into the insulating housing for its mechanical and electrical fixing with the contact spring.
  • the contact spring has a plug socket opposite the conductor connection in the feed direction of the conductor. The socket serves to connect one end of the cable. This creates an electrical plug contact between the component inserted into the socket and the conductor connection of the contact spring.
  • a disadvantage of the known contact spring is that the feed direction of the conductor and the plug-in direction of the socket run in parallel.
  • the contact spring and its insulating housing require a relatively large amount of space at the installation site.
  • this contact spring can often not be used because there is insufficient scope for the plug-in contact and for releasing this plug-in contact.
  • the plug-in contact is then either not possible at all or is associated with such a high assembly effort that mechanical damage to the contact spring and / or the plug-in component is to be feared.
  • the application area of the contact spring which is severely restricted by the arrangement of the conductor connection and socket, often makes their production uneconomical.
  • the invention has for its object to improve the possible uses of the contact spring.
  • the contact spring has a plurality of socket contacts for plug-in contacting an electrical component.
  • the plug-in openings which are usually arranged at right angles to the plug-in direction, are located in different planes at least. Two different levels can be at any angle to each other. Two outer surfaces of the contact spring running parallel to one another also form two different planes. Of course, several socket contacts can be arranged in a single plane. The plug-in openings of the socket contacts, which are at different levels, enable the contact spring to be used in a multifunctional manner.
  • the installation position can be selected from several possible installation positions of the contact spring that is most favorable for the assembly of the contact spring, as well as for the handling of the conductor to be connected to the contact spring and of the plug-in contactable component. This has a space-saving and assembly-friendly effect for entire electrical functional units or electrical devices that are used in combination with contact springs.
  • the socket contacts according to the invention significantly increase the variability of the contact spring and its flexibility during assembly even in difficult installation conditions.
  • the socket contacts of the contact spring ensure that the components to be inserted can be mechanically and electrically fixed to the contact spring from different sides in terms of assembly technology.
  • the socket contacts usually enable detachable plug-in contacting.
  • the socket contacts are preferably designed to be resilient and can receive the plug-in components with a mechanical preload. As a result, the plug-in components are fixed to the contact spring with a good holding force.
  • a single socket contact can also be used alone for mechanical fixing of the entire contact spring.
  • this socket contact takes e.g. an electrically insulated locating pin.
  • the other socket contacts can continue to be used for electrical contacting of components.
  • the contact spring according to the invention enables a particularly simple and mechanically stable plug connection between the contact spring and the 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.
  • the plug directions of two adjacent socket contacts are perpendicular to each other. This is a preferred combination of plug-in directions in order to simultaneously plug-in several components and to save space to be able to arrange on the contact spring. In addition, mutually perpendicular plug-in directions support a simple design of the contact spring and its automated production.
  • the socket contact is designed in the manner of a so-called tulip contact.
  • the tulip contact is penetrated by a cylindrical plug-in opening, the opening edge of which is flanged in the plug-in direction of the element to be contacted.
  • This socket contact improves the mechanical stability of the connector.
  • Claim 4 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.
  • At least one of the two diametrical ends of the socket slot opens into a recess in the contact spring.
  • the recess usually passes through an outer surface of the contact spring and enables improved spring elasticity of the socket contact. This supports the plug-in connection of a component with good holding force on the socket contact.
  • Claim 6 supports the manufacture and use of the contact spring as an inexpensive mass-produced article.
  • Claim 7 creates a particularly stable configuration of the contact spring, the partial strips projecting beyond the spring base body being an integral part of the contact spring.
  • One or more socket contacts can be easily incorporated into the partial strips in terms of production technology, for example using a stamping and bending process, when the contact spring is still in its initial state. All socket contacts can then be easily incorporated into a single metal strip in terms of production technology. This manufacture of the socket contacts can be automated easily and is therefore inexpensive.
  • the bending edges of the at least three partial strips of the contact spring bent against one another run parallel to one another and run in the feed direction of the conductor.
  • the bending edges running in this way support a mechanically stable structure of the contact spring and reduce its wear, which is caused by forces acting on it during the contacting of the components and the conductor.
  • At least one socket contact is produced in terms of manufacturing technology simply in that the contact spring has, as a further partial strip, a connecting plate which is separated from the spring side wall by a bending edge.
  • This connection plate carries at least one socket contact and, when the contact spring is in the bending end state, is at right angles to the spring base body and to the spring side wall.
  • the contact spring acts directly on the conductor inserted into the insulating housing with spring force. Due to their spring elasticity, the connection end adapts to different outer contours of the conductor or the conductor end, without any loss in the electrical connection reliability of the conductor. Different types of conductors can therefore be connected to the contact spring on the contact spring according to the invention by a simple plug-in process. This supports the universal applicability of the contact spring according to the invention. For example, the stripped wire end of a conventional wire can also be connected to the connectors. It is also advantageous that the contact spring of the 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, that contact springs of identical design have connection ends with different spring force when on a multi-pole unit with several contact springs conductors with different cable cross-sections are to be connected.
  • 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 simply formed by an angled section of the contact spring, as a result of which the connection end is constructed in a space-saving manner.
  • the conductor automatically bends the connection end against the spring force when it is fed into the contact spring. 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 longitudinally slotted on the conductor connection, so that two mutually independent conductors can be connected to the same contact spring per connection pole.
  • the conductors have small or different line cross sections, such as is the case in telecommunications.
  • two different conductors can advantageously be mechanically and electrically connected independently of one another with the same pole.
  • the pivoting range of the connection end is limited during the manufacture or release of the clamping fixation. This ensures that the conductor connection acted upon from the outside by the inserted conductor or an assembly tool cannot be stressed beyond its elastic deflection and thus cannot be irreversibly bent, so that the conductor connection has a constant spring force over a long operating time.
  • the measure according to claim 12 supports the mechanically stable support of the externally loaded and thus pivoted conductor connection on the stop tab.
  • Claim 13 proposes a stable metal abutment for the spring leg-like conductor connection. This improves the clamping force exerted on the connected conductor.
  • the spring roof of the contact spring which acts as a metal abutment, has the effect that the contact spring alone accomplishes mechanical and electrical fixing of the conductor. 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 can be easily met. If this contact spring is inserted in an insulating housing, no thermal / mechanical loads on the insulating housing need to be taken into account for fixing the conductor. The insulating housing can therefore be made from a comparatively inferior and therefore inexpensive insulating plastic.
  • the spring roof carries an end stop angled from its plane. This end stop serves for the assembly-appropriate feeding of the conductor to or into the contact spring, in that the end stop limits the feed path of the conductor.
  • the end stop is an integral part of the spring roof and is thereby kept particularly stable in its desired installation position.
  • a flap-like end stop which can be angled from its plane, is formed in the spring roof, which projects in the bending end state of the contact spring in the direction of the spring base body and is preferably arranged at right angles to the spring roof. The end position of this end stop can be taken into account in a stamping and bending process for processing the contact spring and thereby supports automated and cost-effective production of the contact spring.
  • Claim 16 proposes an actuating slot passing through the spring roof in order to apply a tool, for example a screwdriver blade, from the outside to the terminal end and to release the clamping fixation of the conductor.
  • a tool for example a screwdriver blade
  • the actuation slot also acts as an unlocking window.
  • Claim 17 relates to a further embodiment of the contact spring with one or more additional contact elements molded thereon.
  • a contact element can be, for example, a plug pin or solder pin, which is used for the electrical connection of the contact spring to a printed circuit board or another electrical device.
  • the additional contact element then serves as a primary connection.
  • the socket contacts can then serve as secondary connections, for example for parallel connection or for bridging a plurality of contact springs.
  • several contact springs can be oriented differently to one another, which is easily possible due to the variability of the contact spring according to the invention.
  • the additional contact element forms a mechanical fixing means for the contact spring on a mounting surface.
  • the additional contact element can thus serve as a purely mechanical fixing means or as an electrical connection or these two functions in combination with one another.
  • the additional contact element claimed in claim 17 serves as a plug pin or solder pin for direct plug-in fixing of the contact spring with a component, for example a printed circuit board.
  • the socket contacts can then accommodate another electrical component, for example a prong of a contact comb.
  • several contact springs can be bridged. This bridging is required, for example, to connect several protective conductor contacts to connect with each other because an electrical connection of protective conductor contacts via conductor tracks of a circuit board is not possible or even prohibited for safety reasons.
  • several contact springs can be electrically connected in parallel.
  • a further socket contact is released, which can then be used for other contacting purposes, e.g. can be used for bridging (potential multiplication).
  • a contact comb for electrical contacting with socket contacts is the subject of claim 19.
  • the contact prongs of the contact comb inserted into the socket contacts enable a releasable electrical cross-connection between a plurality of contact springs for multiplication of potential in terms of installation technology.
  • Claim 20 relates to an electrical connector for at least one element to be contacted electrically.
  • This connector has an insulating housing and at least one contact spring therein. Associated with a contact spring, the insulating housing contains an insertion opening for receiving the conductor and a plurality of contact openings facing away from the insertion opening for the socket contacts.
  • the socket contacts of the connector serve as the contact end to connect the connector e.g. to be stuck on a circuit board.
  • the socket contact receives a contact pin that is electrically connected to a conductor track of the circuit board.
  • the connector is connected to one component, e.g. a PCB directly plug-in.
  • Each pole is preferably of the connector identical, so that structurally identical contact springs can 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, the connection of many conductors to a multi-pole connector with a large number of poles remains clear and easy to install.
  • Claim 21 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 integrally connected to the contact spring and which interacts with a recess edge of a catch recess formed in the insulating housing, serves as the catch 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.
  • 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.
  • the contact springs 3 assigned to different poles are lined up in a transverse direction 19. In Fig. 1 it is a 5-pin connector 1.
  • the insulating housing 2 has an insertion opening 44 for receiving and fastening the stripped conductor end 12 of a conductor 11 (FIG. 2, FIG. 5).
  • the insulating housing 2 has a contact opening 47 and a facing away from the insertion opening 44 Contact opening 48 as connections to the element to be contacted.
  • the element to be contacted in the exemplary embodiments shown is a connection pin 7 soldered to the printed circuit board 5 (FIG. 6 to FIG. 9).
  • the contact spring 3 clamps the conductor end 12 in the area of the insertion opening 44 and at the same time forms the connecting part to the contact pin 7.
  • the contact spring 3 is in the area of the contact opening 47 and in the area of the contact opening 48 of each penetrated a cylindrical insertion opening.
  • the opening edge of these plug openings is flanged into the insulating housing 2 in the manner of a tulip contact (FIG. 7, FIG. 9, FIG. 11).
  • the tulip contact forms a socket contact 24 and interacts in the manner of a contact socket with the contact pin 7 designed to be complementary thereto.
  • the central longitudinal axes 49 and 50 of the two socket contacts 24 are at right angles to one another (FIG. 7, FIG. 9). In other words, the plug directions 4.62 of the two socket contacts 24 are at right angles to one another.

  • the socket contact 24 is diametrically slotted by means of a longitudinal slot 51 or 52 running in the longitudinal direction 9 of the spring (FIG. 12).
  • the longitudinal slot 51 is extended at one longitudinal end by a circular shaped recess 60, the longitudinal slot 52 by the rectangular shape of the fixing tab 30 in order to improve the elasticity of the socket contacts 24.

  • the conductor connection 10 fixes the inserted conductor end 12 with its free end 16 pointing approximately in the feed direction 13 of the conductor 11 and is therefore effective in the manner of a barb against removal of the conductor 11 against the feed direction 13.
