Definitions

  • the object of the invention is a contact for providing an electrical connection in an electrical connector, an electrical connector housing, and an electrical connector.
  • Publication CN210040659U shows an automotive charging gun that comprises a gun head equipped with multiple openings. One end of the contact is inserted into an appropriate socket, through a contact-mounting opening, and the other end is connected to the wires of the electrical connector.
  • the first contact-mounting portion is positioned on the side wall of the mounting opening of the pins of the contact housing and the second one is positioned on the outer surface of the contacts, the second mounting portion being mated with the first mounting portion to restrict axial movement of the contacts within the contact housing.
  • the pin of the charging gun is rigidly fixed and not easy to loosen, the charging stability is better and the service life is extended.
  • the contacts according to this invention have one recess (no.
  • Another Chinese utility model CN210379629U discloses an electrical connector for cars in which contacts have at least two narrowings used to immobilise them. In contrast, neither of the narrowings is provided with sealing means. The watertight properties of the electrical connector are achieved by using a seal on the outside of the entire connector.
  • Chinese utility model CN209709269U discloses a car charging plug with good water tightness, having multiple openings into which first ends of contacts are inserted while the other ends of the contacts are connected with conductive wire conductors.
  • the contacts are mounted in a rubber core located in the gun head.
  • the said contacts have at least two recesses (no. 21 and 23), wherein in the recess 21 a seal (no. 22) is placed, and thus the recess 21 is used to make the device watertight, and the recess 23 is used to snap the contacts into the housing.
  • the recess 21 with the seal 22 is closer to the contact, and then there is the recess 23.
  • the order of the recesses may be different. It is explained, however, that the said order makes the connector watertight and prevents water from entering the connector from the front.
  • the aim of the present invention is to ensure that the electrical connector is completely watertight and dustproof during operation and after disconnecting the connector from the socket.
  • Water entering the interior of the plug when holding the plug in a vertical position should stop at the seals (O-rings) located on each individual contact and at the seal (O-ring) on the contact housing. In this way, after shaking the plug out, one can plug it back into the socket without fear of a short circuit.
  • a contact for providing an electrical connection at an electrical connector comprising:
  • its cross section is substantially circular.
  • the said projection is in the form of a ring, i.e. an area of increased diameter with respect to the diameters of adjacent areas of the contact.
  • the first narrowing is in the form of a ring-shaped area of a reduced diameter with respect to adjacent areas of the contact.
  • the said seal is in the form of a ring, preferably of rubber, most preferably of acrylonitrile-butadiene rubber, especially with a hardness of 70 Shore (trade name: NBR 70).
  • the second narrowing is in the form of a ring-shaped areaof a reduced diameter with respect to adjacent areas of the contact.
  • it is made of a material selected from the group consisting of: CuZn36Pb3 alloy (trade name: MO61z4) and CuZn40Pb2 alloy (trade name: MO58).
  • an electrical connector housing surrounding the contacts for providing an electrical connection configured to cooperate with the contact described above, having:
  • the said openings are circular in cross-section.
  • it has at least two latches, and preferably three latches, inside the opening.
  • it has seven openings arranged in the same circle, preferably three latches in each said opening, which are positioned at an angular distance of 135°, 90°, and 135° from each other.
  • it has fifteen openings arranged on two concentric circles, preferably ten openings on the outer circle, five openings on the inner circle, preferably three latches are positioned at an angular distance of 135°, 90° and 135° from each other in each opening located on the outer circle, while in each opening located on the inner circle, three latches are positioned at 120° from each other.
  • plastic in particular of reinforced polyamide with a glass fibre content in the amount of 30%.
  • a particularly preferred material is reinforced polyamide 6 with a glass fibre content in the amount of 30% (trade name: PA6+30GF).
  • an electrical connector including the contacts described above, placed in the housing described above.
  • a pin 1 for providing an electrical connection in an electrical connector has:
  • the contact 1 is mounted in a housing 7 from below ( Fig. 2 ). Its specific position is ensured by several elements ( Fig. 3 - Fig. 6 ). In each opening 6 of the housing 7, regardless of whether it is a housing with fifteen openings or seven openings, there are three latches 8 that snap onto the second narrowing 5 when the contact 1 is at an appropriate depth in the opening 6. In other words, when inserting the contact 1 into the opening 6, it is guided in an opening with a slightly greater transverse dimension than the dimension of the contact 1, then, when the edge A of the contact 1 ( Fig. 2 ) touches the latches 8, it begins to spread/widen them.
  • the latch 8 When inserting the contact 1 into the opening 6 deeper, the latch 8 will meet the notch/second narrowing 5 in the contact 1. At this point, the elastically deformable latches 8 from the housing 7 will want to return to their natural position from before being “spread” and will lock onto the edge of the contact 1, thus blocking its upward movement. If it were the only mounting element, the contact 1 could be pushed deeper into the opening 6, while the projection 2 ( Fig. 1 ) of the contact 1 abuts the edge of the housing opening (reference B, Fig. 2 ), thus preventing the contact 1 from sliding further into the opening. In this way, the contact 1 is prevented from moving along the opening 6 of the housing 7 - by blocking the contact 1 in a fixed, desired position, an up and down movement is prevented.
  • the projection 2 is in the form of a ring, i.e. an area of increased diameter with respect to the diameters of adjacent areas of the contact 1.
  • the positioning (centring) of the contact 1 in relation to the opening 6 takes place by means of the projection 2 ("ring", “plate”, “collar") and thanks to the three latches 8 inside the opening 6 of the housing 7.
  • the latches 8 are not evenly distributed.
  • arrangement of the latches 8 is different: in ten openings on the outer circle (of larger diameter), three latches 8 are arranged inside the opening 6 circumferentially at an angular distance of 135°, 90° and 135° ( Fig. 9 ), while each of the five openings on the inner circle (of smaller diameter) has three latches 8 distributed at 120° from each other.
  • each of the seven openings has three latches 8 spaced at 120° from each other.
  • it is made of a material selected from the group consisting of: CuZn36Pb3 alloy (trade name: MO61z4) and CuZn40Pb2 alloy (trade name: MO58).
  • the housings according to the invention can preferably be made of polyamide, in particular of reinforced polyamide 6 with a glass fibre content in the amount of 30% (trade name: PA6+30GF).
  • the electrical connector including contacts and housings according to the invention has the following advantages: Additionally, they protect the wires inside the plug against the influence of liquids and dust, which allows the connectors to be used and serviced even in the most unfavourable weather conditions in the open air.
  • the connector according to the invention is applicable in the automotive industry, mainly for tractors and semi-trailers, acting as a connector between the above-mentioned elements.
  • Functions of connectors depend on their design, and here, for example, the EBS connector controls brakes on the trailer, and the 15-pin connector and the cable adapter support the entire lighting on the trailer.
