Definitions

  • the present invention relates generally to electrical connectors to be connected to ribbon or flat cables and, more particularly, to a lock mechanism for such electrical connectors.
  • Fig. 12 shows a conventional electrical connector of this type.
  • a connector plug c is connected and locked to a connector socket a by engaging a lock arm f of the plug c with a lock shoulder e of the socket a so that the pin receiving apertures b of the connector socket a receive the contact pins g of the connector plug c for providing electrical continuation.
  • a lock mechanism according to the preamble of claim 1 is known from US-A-4 458 073.
  • the lock arms are depressed with two fingers to put them into the lock arm receiving recesses, thereby reducing the width of the connector plug, resulting in a reduced connector size.
  • the lock arms are inserted into the lock recesses without resistance and, when released, flex outwardly so that the lock projects engage the lock shoulders to lock the connector plug to the connector socket. Since the lock mechanism is of the inner lock type in which the lock projections engage the lock shoulders within the lock recesses, it is resistant to vibrations.
  • the front portions of the lock arms project through the cutouts of the connector socket while the sloped surfaces of connector socket provides indentations sufficiently large to receive the fingers. consequently, when the lock arms are depressed, the fingers rest in the indentations and engage the end projections of the connector socket so that it is easy to pull the connector plug out of the connector socket.
  • an electrical connector consists of a connector socket 1 which is to be mounted on a board and a connector plug 2 which is to be connected to the connector socket 1.
  • the connector socket 1 includes a socket block 3 made from a synthetic resin so as to have a plug cavity 4 which opens in the front end 3a.
  • a number of terminals 5 are arranged at regular intervals lengthwise of the plug cavity 4.
  • the contact portion 6 of each terminal 5 projects into the plug cavity 4 from the terminal support portion 4a of the socket block 3.
  • the leg portion 7 of each terminal 5 projects outwardly from the rear wall 3d of the socket block 3 and is bent downwardly at right angles.
  • a pair of lock recesses 8 each having a pair of lock shoulders 9 and 10 are formed on opposite side walls 3b and 3c of the socket block 3.
  • Each side wall has a central cutout 11 in the front portion and a sloped surface 12.
  • the connector plug 2 includes a plug block 13 which is molded from a synthetic resin so as to have a pair of lock mechanisms 14 on opposites sides 13a.
  • the lock mechanism 14 has a lock arm 15 which extends backwardly from the front end of the block side 13a.
  • the lock arm 15 has a base portion 15a which extends parallel with the axis 88 and a front portion 15b which extends outwardly with respect to the axis 88.
  • the front portion 15b is made thicker than the base portion 15a and is knurled on the outside 16 for preventing the finger from slipping.
  • a pair of lock projections 18 and 19 are formed on opposite sides of the base portion 15a.
  • a pair of lock arm receiving recesses 20 are formed on the side walls 13a (Fig. 11) for receiving the front portions 15b of the lock arms 15.
  • a pair of end projections 21 project outwardly from the rear end of the plug block 13 providing the lock arm receiving recesses 20 with an end wall.
  • a number of contact terminals 22 are arranged at regular intervals lengthwise of the plug block 13 and connected to a flat cable 23.
  • the connector socket 1 is mounted on a board 24 by soldering the leg portions 6 of the terminals 5 to the through holes 25.
  • the connector plug 2 is fitted into the plug cavity 4 of the connector socket 1 so that the contact terminals 22 are brought into contact with the contact portions 6 of the terminals 5 for providing electrical continuity.
  • the lock arms 15 of the lock mechanisms 14 are depressed with two fingers to put them in the lock arm receiving recesses 20 so that the lock arms 15 are inserted into the lock recesses 8 without resistance. After insertion, the fingers are removed to release the lock arms 15 so that they flex outwardly with their own elasticity. Consequently, the lock projections 18 and 19 engage the lock shoulders 9 and 10 to lock the connector plug 2 to the connector socket 1.
  • the front portions 15b of the lock arms 15 are depressed with two fingers to put them in the lock arm receiving recesses 20, thereby releasing the lock projections 18 and 19 from the lock shoulders 9 and 10 for removal of the connector plug 2 from the connector socket 1.
  • the fingers rest in the indentations of the sloped surfaces 12 of the connector socket 1 coming into contact with the end projections 21. This makes it easy to pull the connector plug 2 out of the connector socket 1.
  • the electrical connector according to the invention it is possible to reduce the width of the connector plug 2, thus minimizing the size of the electrical connector. Since the lock arms 15 are depressed into the receiving recesses 20 before locking, it is possible to insert the lock arms 15 into the lock recesses 8 without resistance. When released, the lock arms 15 flex outwardly so that the lock projections 18 and 19 of the lock arms 15 engage the lock shoulders 9 and 10 of the connector socket 1 to lock the connector plug 2 to the connector socket 1.
  • This lock mechanism of the inner lock type in which the lock arms 15 engage within the lock recesses 20 is resistant to vibrations.
  • the front portions of the lock arms 15 project through the cutouts 11 of the connector socket 1 while the sloped surfaces 12 provide indentations which are sufficiently large to receive the fingers.
  • the fingers rest in the indentations of the sloped surfaces 12 of the connector socket 1 so that they engage the end projections 21 of the plug connector 2 without difficulty.
