Definitions

  • the present invention relates to a connector using prismatic or rectangular contact pins and cylindrical receptacle contacts for receiving the prismatic contact pins and, more particularly, to a connector suitable as a waterproof surface-mounting connector.
  • a known conventional connector of this type uses cylindrical contact pins and cylindrical receptacle contacts.
  • this connector When this connector is to be mounted on, e.g., a surface of a printed circuit board, the pins cannot be perfectly brought into surface contact or soldered with the surface of the board because the pins are cylindrical. This drawback is very important when the number of contact pins is increased. Strong demand therefore has arisen for the development of a highly reliable connector free from the above drawback.
  • a connector characterized by comprising a plurality of contact pins having a rectangular cross-section, a plurality of receptacle contacts having a circular cross-section and adapted to receive corresponding contact pins, and a housing having a plurality of storage grooves for respectively receiving the receptacle contacts, each of said receptacle contacts being provided with a contact spring formed on an outer circumferential surface of each receptacle contact and a recessed portion formed on the circumferential surface of each receptacle contact at a position opposite to said contact spring, said contact spring and said recessed portion cooperating to hold a corresponding one of said contact pins which is inserted therein.
  • FIG 1A shows a contact pin 10 used in a connector according to the present invention and a receptacle contact 20 for receiving the contact pin 10.
  • the contact pin has a square cross-section (the cross-section could be rectangular), and the receptacle contact has a circular cross-section.
  • each receptacle contact has a dimple 23 on part of its outer circumferential surface (the dimple 23 will be described in detail later).
  • a ferrule may be formed at the front end of each receptacle contact.
  • Figures 1B and 1C show a connecting state of each contact pin and a corresponding receptacle.
  • the receptacle contact has a contact spring 21 formed on its outer circumferential surface and a recessed portion 22 formed on the outer circumferential surface portion opposite to the contact spring 21.
  • the contact spring 21 and the opposite recessed portion 22 hold the inserted contact pin.
  • the wall of a main body of the contact is partially cut and bent indward to constitute the tongue-like contact spring 21.
  • FIGS 2A to 2C show the housing in which receptacle contacts are mounted. As shown in Figures 2A to 2C, the housing has lance members 32. Each lance member is engaged with the recessed portion of the corresponding receptacle contact inserted into the housing and holds this receptacle contact therein.
  • each insertion hole has a square cross-section to receive a prismatic or rectangular pin.
  • each receptacle contact is housed in the corresponding storage groove such that a leading end of a wire 38 is terminated, and the terminal end extends through a corresponding rubber bushing 35 fitted in a corresponding opening 34 formed at the rear portion of the housing. This bushing seals the corresponding contact to obtain a waterproof structure.
  • the illustrated housing is a male housing which is then fitted in a female housing 40.
  • the male housing is fitted in the female housing 40 such that a latch projection of the female housing is fitted in a lock hole 37 formed in a latch spring 36.
  • Figure 3 shows a detailed structure when the male and female housings are engaged with each other.
  • a member 41 for fixing the lance members respectively engaged with the receptacle contacts is fitted in the front end portion of the male housing.
  • the member 41 may be omitted such that each lance member can be biased in the corresponding storage groove.
  • the male and female housings are engaged with each other through a waterproof O-ring 42.
  • Each receptacle contact has directivity given by the dimple formed on its outer circumferential surface.
  • a guide groove 39 is formed in each storage groove of the housing to receive the receptacle contact with a dimple.
  • the contact pins of this embodiment are mounted in a header surface-mounted on a printed circuit board 50.
  • Figures 4A and 4B show a structure in which each groove 35B is formed in a through hole 35A of each bushing to receive the corresponding receptacle contact with a dimple.
  • Figure 5 shows another embodiment in which an opening for housing the bushings is partitioned by a partition wall 61.
  • a plurality of receptacle contacts are housed in the housing through each divided opening.
  • Other arrangements of this embodiment are the same as those of the previous embodiment.
  • a plurality of bushings can be used by forming a plurality of openings, so that an improvement of the waterproof effect of the bushings can be expected.
  • the opening can be partitioned by a large number of partition walls.
  • openings defined by partition walls may be formed in units of storage grooves, and wires each with a rubber bushing may be fitted in the openings, respectively.
  • a rib is formed at a lower portion of the rubber bushing in place of the partition wall, and a fitting portion which can fit with the rib may be formed.
  • FIG 6 is an exploded view of the female housing.
  • the female housing comprises a housing body, O-rings 42, boards 50, and frames 51 from which various pins 10 extend outward.
  • a two-storey frame structure is sandwiched between the upper and lower boards 50.
  • the connector can be easily surface-mounted on, e.g., a surface of a printed circuit board. At the same time, since the contact area between the connector and the board is increased, soldering can be appropriately performed.
  • the prismatic pins can be formed by pressing and result in low cost as compared with cylindrical pins (for example, the pins are connected by a plurality of carriers).
  • each prismatic pin can be clamped between the contact spring and the recessed portion which latter two are formed in the corresponding receptacle contact, the pin can be appropriately brought into contact with and electrically connected to the receptacle.
  • the receptacle contact which receives this has a circular cross-section, and therefore each pin easily extends through a waterproof rubber bushing. Therefore, the connector of the present invention can also serve as a waterproof connector.
