Definitions

  • the invention relates to a pressure-contact connector with two plug-in connector parts, of which at least a first connector part, a plurality of pressure contact pins, which are mounted axially displaceably in the connector part against a restoring force comprises.
  • Such pressure-contact connectors have a good resistance even under difficult environmental conditions and are used for example in the audio and telecommunications industry in the police and military but also for medical applications.
  • the connector parts of the pressure-contact connector have a good tightness against water and weathering even in the unmated state.
  • the number of contacts in the two connector parts depends on the particular application. In the usual applications, at least two pressure contact pins are provided. In most embodiments, only the contacts of a connector part are designed as pressure contact pins, while in some embodiments, the contacts on both connector parts can be designed as pressure contact pins.
  • the contacts of the two connector parts face each other in the respective mating surfaces of the connector parts.
  • pressure contact connectors can not create a short circuit between the contacts of the connector parts during the plugging process.
  • This connection technology has become established in a number of application areas due to its operational reliability.
  • By such generic pressure contact connectors can be omitted in the connector parts on long, far above the level of contact of the housing body of the connector parts in the assembled state excellent solid pins that can easily bend or break in use.
  • the pressure contact pins are in the unmated condition slightly above the contact plane of the connector part before and are pressed during mating of the two connector parts through the contacts of the other connector part against the restoring force in the associated connector part.
  • the pressure contact connectors thus allow a high reliability of the contact connection with a good shock and vibration resistance.
  • the publication DE 35 36 142 A1 discloses a multi-pin connector for motor vehicles, wherein the contact pins formed in one piece and can be moved axially against a compression spring in the housing of the plug. The axial movement of the contact pins is compensated by the connected lines.
  • the arranged in the housing bore receives the compression spring and the contact pin, wherein on the back of the housing, the contact pin is provided with a flange which prevents slipping out of the contact pin in the direction of the spring force but also a subsequent mounting or dismounting of the one-piece contact pins.
  • the EP 1 102 360 A1 describes a further connector with pressure contacts, which are arranged in a housing, wherein the movable two-part pressure contacts are sealed by the circumferential sealing lip of a seal to the interior of the housing towards the ingress of moisture impermeable.
  • Pressure contact connectors in addition to their overall good resistance to harsh environmental conditions, also have good contact system reliability in the event of shocks, vibrations and extreme temperatures, making them attractive for many applications.
  • the complexity of the design due to the function leads to a complex production and high production costs, which In turn, the use of such connectors is reduced to applications with high reliability requirements.
  • the object of the invention is therefore to reduce the production cost and production costs of generic pressure contact connectors with a constant or improved functionality by a simple design.
  • the first connector part has a connection region for producing a solid electrical connections, wherein the connection region comprises a compensation device for the axial displacement of the pressure contact pins.
  • the compensation device compensates for the axial displacement of the pressure contact pins and thereby ensures the function of the pressure contact connector and the repeatability of the assembly operation. Compared to conventional balancing devices, this arrangement allows a much simpler construction of the pressure-contact connector, and thus a reduction in the manufacturing cost.
  • the compensating means may comprise a cavity and the pressure contact pins may be connected in the connecting region with flexible connecting leads, which are in the cavity, the axial displacement of the pressure contact pins compensating, movable.
  • the cavity is preferably formed by the housing walls of the connector part, wherein the cavity is usually filled with air, but also on the media are possible, which allow compensation of the axial displacement.
  • the pressure contact pins may be formed as rigid units. So far, pressure contact pins are designed as telescopic units, wherein at least one axially movable part and a firmly anchored in the housing part cooperate such that a formed as a socket part and a pen designed as a part of the pressure contact pin telescope into each other. In this case, a spring device necessary for the return of the pressure contact pins can be supported on the telescoping parts of the pressure contact pins. In particular, in combination with a arranged in the connection region of the first connector part compensation means for the axial displacement allow the formed as a rigid units pressure contact pins a much simpler construction of the pressure-contact connectors.
  • the pressure contact pins may be integrally formed. As a result, a faster assembly and thus lower installation costs is possible.
  • the pressure contact pins are made of an electrically conductive material, in particular a copper-zinc alloy, and have a corrosion-resistant surface coating, in particular of gold.
  • Such pressure contact pins have very low contact resistance and a permanently high contact reliability even at low voltages and currents. This allows a high level of operational reliability even under extreme or corrosive environmental conditions.
  • a simple and cost-effective constructive solution for the provision of the restoring force can be made possible in that the restoring force by a spring means, in particular a helical compression spring, is designed to be applied.
  • the connector parts have contact surfaces and guide means, wherein the guide means are configured so that when mating the connector parts in each case two opposite contact surfaces perform a relative wiping movement to each other.
  • the guide means By the guide means a short circuit between the contacts of the connector parts is prevented during the insertion process of the connector parts.
  • the relative wiping movement between each two opposing contact surfaces leads to a cleaning of the contact surfaces due to the friction between these surfaces, which increases the contact reliability of the connectors.
  • a variant provides that the pressure-contact connector has a bayonet lock.
  • the bayonet closure allows a high degree of functional reliability of the closure mechanism, even under difficult environmental conditions, which is particularly required in military or off-shore applications.
  • a further embodiment provides that the pressure-contact connector has a screw cap.
  • Screw-type connectors enable a secure and comprehensible complete closure of the closure and are used in particular where it depends on a secure contact connection, eg medical, communications and space technology.
  • pressure contact pins are partially surrounded by a seal that seals the pressure contact pins to the environment. This seal prevents ingress of dirt and moisture into the area of the pressure contact mechanism.
  • An expedient embodiment provides that the seal is made waterproof up to an overpressure of 1 bar.
  • the connector parts in a non-mated condition are also waterproof under water to water depths of 10 m. This embodiment is also sufficient to protect the connector parts over simple cleaning methods.
  • the sliding seal can be made waterproof to an overpressure greater than 5 bar, preferably greater than 10 bar. This allows on the one hand a protection of the open connector parts against intensive cleaning by high pressure and on the other to water depths of over 50 m, or over 100 m, a sealing effect against the ingress of water.
  • the seal may be configured as a bellows seal.
  • Bellows seals are usually constructively connected to the pressure contact pins and carry out the axial movement of the pressure contact pins, whereby they achieve a particularly good sealing effect.
  • a further embodiment provides that the seal is designed as a sliding seal and the pressure contact pins are guided relatively displaceable in the sliding seal, so that the pressure contact pins when plugging the connector parts sealed slide along the sliding seal.
  • the formation of the seal as a stationary sliding seal allows the sealing of the pressure contact mechanism of the first connector part with a single substantially flat seal.
  • the sliding seal can seal the pressure contact mechanism over the entire displacement of the pressure contact pins against the ingress of water and other substances from the environment. In addition to the cost savings for the seal a lesser effort in the assembly of the connector parts is possible by the sliding seal.
  • the sliding seal can be made together with at least a part of the first connector part in a 2-component injection molding process.
  • This manufacturing process reduces the proportions of the parts needed to assemble the press-contact connectors.
  • the two-component injection process results in that the sliding seal can be connected to the jointly produced part of the first connector part, whereby moisture penetration between the sliding seal and the simultaneously molded part is made impossible.
  • thermoplastic elastomer TPE
  • Thermoplastic elastomers have good processability, making them particularly suitable for injection molding. Also, the elastic properties, the dimensional stability and the wear resistance of thermoplastic elastomers are good, which allows a good, lasting sealing effect.
  • the first connector part has a contact element, which comprises the seal and the pressure contact pins, and is configured for both pressure-contact connector with a bayonet lock and for pressure-contact connector with a screw can be used.
  • the pressure contact mechanism exhibiting contact element makes it possible to choose the locking mechanism independently of the contact element.
  • the contact element may be designed as an insert, which can be used in the same way in housing with different closure mechanisms. Such a design makes it possible to use the same components for different series. The higher number of individual components allow a reduction in component costs.
  • the contact element may be further provided on a connection side for producing a solid electrical connection with a support plate in which the pressure contact pins are relatively displaceable guided by the support plate through the support plate and wherein the support plate for supporting a the restoring force of the pressure contact pins applying spring device is used.
  • the support plate By attaching the support plate, the pressure contact pins can already during installation in the area of the connection side be held in position with little play. Also, the leadership of the pressure contact pins in the support plate increases the reliability of the pressure-contact connector. With the support of the spring means for resetting the pressure contact pins, the support plate takes over the leadership of pressure contact pins another function, thereby reducing the necessary number of components.
