Definitions

  • This invention relates to a connector fitting to a connector connected to a coaxial cable, and more particularly to such a connector in which the number of component parts is reduced, and a relative movement (shaking movement) between the parts is reduced so as to enhance high-frequency characteristics.
  • Japanese Patent Publication Hei.8-306435 discloses a connector (hereinafter referred to as "coaxial connector") connected to a coaxial shielded wire which handles a high-frequency signal used in the connection of a car navigation system, an on-board communication system, an AV equipment, an OA equipment and so on.
  • such a coaxial connector mainly includes: a molded body 101 of a square box-like shape having an open front side; an L-shaped contact pin (male terminal) 102 received in the molded body 101; an insulator 103 receiving and holding the contact pin 102; an L-shaped, tubular inner shield cover 104 of a square cross-section mounted within the molded body 101 in surrounding relation to the contact pin 102; and an outer shield cover 105 fitted on an outer periphery of the molded body 101.
  • This coaxial connector is mounted on a printed wiring board 106, and forms a receptacle connector (socket-type connector).
  • the contact pin 102 is held by the insulator 103 in such a manner that one end portion of this contact pin 102 is exposed to a connector mounting-receiving chamber 108.
  • a mating connector 107 of the plug-type can be fitted into the connector mounting-receiving chamber 108.
  • the contact pin 102 and the insulator 103 are received in the inner shield cover 104 in a surrounded manner.
  • the contact pin 102, the insulator 103 and the inner shield cover 104 are fixed to the molded body 101 by a retaining member 109 having serration or teeth.
  • the retaining member 109 is held between the insulator 103 and a rear mounting portion 101a of the molded body 101.
  • the outer shield cover 105 is pressed down from the upper side to be fitted and mounted on the molded body 101.
  • the outer shield cover 105 has a tongue-like connection portion 110 which is inserted in a space between a rear plate portion 104a and a stamped portion 104b of the inner shield cover 104, thereby electrically connecting the outer shield cover 105 to the inner shield cover 104.
  • An ground terminal 111 extends downwardly from a lower end of a side plate of the inner shield cover 104, and an ground terminal 112 extends downwardly from a lower end of a side plate of the outer shield cover 105.
  • These ground terminals 111 and 112 extend through the printed wiring board 106, and are soldered to a circuit pattern on this board 106, thereby grounding the inner and outer shield covers 104 and 105.
  • the inner shield cover 104 and the outer shield cover 105 can be easily connected together without the need for a cumbersome operation such as a bending operation and a soldering operation, and the grounding of these shield covers can be effected easily.
  • the coaxial connector of the above construction includes the molded body 101, the contact pin 102, the insulator 103, the inner shield cover 104, the outer shield cover 105 and the retaining member 109. Therefore, the number of the component parts is large, so that the cost is high. And besides, in the case where the number of component parts is large, a gap is formed between the parts combined together, because of dimensional tolerances required for facilitating the assembling operation, and such gaps are accumulated to cause a large shaking movement.
  • the above coaxial connector is used particularly for sending and receiving a high-frequency signal relative to an on-board equipment mounted on an automobile or the like, and therefore such a shaking movement lowers high-frequency characteristics.
  • Japanese Patent Publication Hei.8-153557 and U. S. Patent No. 5,662,480 disclose coaxial connectors of the type in which an inner housing and an outer housing are formed integrally with each other.
  • these connectors are ordinary commercial ones, and are not originally designed to be mounted on an automobile, and therefore any countermeasures against the vibration of an engine and a temperature change in a passenger room have not been taken. Therefore, such connectors are not suited for use as an on-board connector required to provide high-frequency characteristics.
  • the number of the component parts is large in the conventional coaxial connectors. Therefore, there have been encountered the problems such as the increased cost and the lowered high-frequency characteristics due to a relative movement between the parts, and besides these conventional connectors are not suited for use as an on-board connector.
  • This invention has been made in order to solve the above problems, and an object of the invention is to provide a connector in which the number of component parts is reduced, and an assembling operation, needed for a single product, is reduced so as to reduce a relative movement between the parts, thereby enhancing high-frequency characteristics and achieving a low cost design.
  • a connector of the invention which includes an outer housing portion, having a connector mounting-receiving chamber into which a mating connector can be fitted, and an inner housing portion which has a terminal mounting-holding portion, and is formed integrally with the outer housing portion, wherein a terminal and a shield casing, surrounding an outer periphery of the terminal, are mounted and held on the terminal mounting-holding portion, and one end portion of the terminal is adapted to be connected to an on-board printed wiring board whereas the other end portion of the terminal can be connected to a mating terminal of the mating connector, and a withdrawal prevention lock portion for retaining the mating connector is formed on the outer housing portion.
  • outer housing portion and the inner housing portion are formed integrally with each other, and therefore the number of the component parts is reduced, and therefore a relative movement (shaking movement) between the parts is suppressed. Therefore, only one assembling operation is needed for the single product, and therefore the cost can be reduced.
  • the shaking movement is thus reduced by reducing the number of the component parts, and besides the withdrawal prevention lock portion for retaining the mating connector is formed on the outer housing portion, and therefore even in the case where the connector of the invention is mounted on an automobile, this connector can sufficiently withstand the vibration of the automobile, and therefore high-frequency characteristics will not be adversely affected.
  • a positioning engagement hole is formed in the shield casing, and a shield casing-retaining portion is formed on the inner housing portion, and is engaged in the positioning engagement hole.
  • the shield casing-retaining portion formed on the inner housing portion, is engaged in the positioning engagement hole formed in the shield casing, and therefore the shield casing can be fixed to the terminal mounting-holding portion without shaking.
  • the terminal is insert molded in the terminal mounting-holding portion.
  • the terminal Since the terminal is insert molded in the terminal mounting-holding portion, the number of the component parts of the connector is further reduced, and besides a relative movement between the terminal and the terminal mounting-holding portion is eliminated.
