  • FIG. 1a is a plan view showing a panel 100 which constitutes a casing of a numerical controller, a machine tool or the like, and a stationary connector 101 mounted on the panel 100
  • FIG. 1b is a front view showing the panel 100 and the stationary connector 101
  • FIG. 1c is a cross sectional view of the stationary connector 101 along a break line A-A' in FIG. 1b.
  • the stationary connector 101 has a plurality of pins 102 arranged in vertically stratified two rows. In each row, the pins 102 are arranged with a predetermined space, and the upper and lower rows are transversely shifted with each other by half of the predetermined space. As shown in FIG. 1c, pins 102 are pressed into through holes formed in a body 101a of the stationary connector 101 from behind the body, and projection of distal ends of the pins are adjusted by rectangular contact members 103 which are formed integrally with proximal ends of the pins 102 to project in the diametrical direction of the pins. A contact member 103 of a pin 102 in the upper row in FIG.
  • Apertures 105 as shown in FIGS. 1a and 1b are often provided in the body 101a of the stationary connector 105 at appropriate positions for engagement with a male connector of an associated one, or for regulating orientation characteristic in molding the connector and/or preventing warp after the molding.
  • the stationary connector 101 is attached to a rear surface of the panel 100 so that its front surface aligns with an opening 106 of the panel 100. Between an outer periphery of the stationary connector 101 and a periphery of the opening 106 remains a gap as shown in FIGS. 1a, 1b and 1c.
  • the stationary connector 101 is attached to the panel 101 by L-type fixtures 107, and nuts and screws or the like as shown in FIG. 1c.
  • the prior art as shown in FIG. 1 has a problem that dust and oil may enter a casing of a numerical controller, a machine tool, etc. through the gap between the outer circumference of the stationary connector 101 and the opening 106 of the panel 100, or through the apertures 105 of the stationary connector 101, depending upon an ambience in which the numerical controller, the machine tool, etc. are placed. Further, oil of high permeability may enter the casing through the portion where the pins 102 are pressed into the through holes of the molded body of the stationary connector 101.
  • An object of the present invention is to provide a connector module capable of preventing dust and oil from entering a casing of a numerical controller, a machine tool or the like through an opening for mounting a connector on an industrial machine, or through a stationary connector.
  • a connector module of the present invention comprises: a stationary connector having a receiving portion to receive an associated connector externally of the industrial machine and disposed inside the casing so that the receiving portion is positioned at an opening formed on the casing; a covering member having an opening corresponding to the receiving portion of the stationary connector, for covering outer surfaces of the stationary connector except the receiving portion; and a sealing member for sealing a gap between a front face of the covering member and the opening of the casing.
  • a connector module 1 of the present embodiment has a covering member 2 for covering the whole of a stationary connector 101 except a receiving portion for receiving an external associated connector, i.e., except a lefthand end of the stationary connector 101 in FIG. 2c, and a sealing member 3 for sealing a gap between a front surface of the covering member 2 and an opening 106 of a panel 100.
  • the sealing member 3 is formed into a shape of a rectangular frame so as to surround an opening of the front surface of the covering member 2, and is bonded integrally to the front surface of the covering member 2.
  • the sealing member is preferably made of elastic and oil-proof material such as rubber, urethane, etc.
  • Fig. 3 shows an example of splitting of the covering member 2 in a case where the covering member 2 comprises two parts.
  • a body member 2a has four wall portions forming an upper wall 4, left wall 5, right wall 6 and rear wall 7 of the covering member 2, respectively, and a bottom cover 2b has a wall portion forming a lower wall 8 of the covering member 2.
  • the covering member is formed integrally by bonding the body member 2a and the bottom cover 2b, so that the stationary connector 101 is fitted in a hollow portion of the covering member 2 without any gap inside the covering member 2.
  • a recess 10 is formed at an upper surface of the bottom cover 2b to allow a lower surface of the stationary connector 101 to be fitted therein.
  • a groove 9 corresponding to the thickness of a flat cable 104 is formed in the recess 10 so as to prevent interference of the flat cable 104 and the upper surface of the bottom cover 2.
  • a lower end of the rear wall 7 of the body member 2a is formed to project downward corresponding to a depth of the recess 10.
  • the flat cable 104 connected to the stationary connector 101 is interposed between the lower end of the rear wall 7 of the body member 2a and an upper surface of the groove 9 of the bottom cover 2b, to thereby seal the inside space of the covering member 2 with the stationary connector 101 fitted therein from the outside space in cooperation with the body member 2a and the bottom cover 2b.
  • the recess 10 is provided at the upper surface of the bottom cover 2b only to ensure positioning of the bottom cover 2b relative to the body member 2a using the stationary connector 101 interposed therebetween when bonding the body member 2a and the bottom cover 2b. Therefore, it is possible to omit the recess 10.
  • the groove 9 for passing the flat cable therethrough is necessary.
  • the projection of the lower end of the rear face 7 of the body member 2a is not necessary, and therefore, there is at least an effect of simplifying the structure of dies for molding the body member 2a and the bottom cover 2b.
  • the lower end projection of the rear face 7 and the recess 10 are omitted, it is necessary to design the length of the left wall portion 5, the right wall portion 6 and the rear wall portion 7 of the body member 2a longer in the vertical direction by the amount corresponding to the depth of the recess 10.
  • a core corresponding to the inside space of the covering member 2 is provided in a movable die
  • a core corresponding to the groove 9 is provided in a stationary die so that it is slidably in contact with a side surface of the core for the inside space
  • two pins for forced cutting are respectively provided in side open slide blocks of the movable die so as to serve as cores for the respective through holes 11 for screws.
  • the stationary connector 101 may be forced into the covering member 2 ignoring an undercut for the thickness of the flat cable 104 attached to the stationary connector 101.
  • a sealing member 3 as shown in FIGS. 2a-2c is bonded to the front face of the opening portion of the covering member 2 in which the stationary connector 101 is fitted, and the covering member 2 is fixed to a rear surface of the panel 100 by L-type fixtures 107' as shown in FIG. 2c.
  • Each L-type fixture 107' is fixed to the connector cover 1 by a nut and a screw using the through hole 11 of the covering member 2 in the conventional manner.
  • the stationary connector may have various size, shape and manner of connecting with the cable, and the above described structure is set forth only as one example.
  • the structure may be realized provided that the stationary connector is fitted in the completely sealed covering member, the cable from the stationary connector can be lead into the casing of a numerical controller, machine tool, etc. with a sealed state of the covering member is maintained, and a gap between the connector cover and the opening 106 of the panel 100 can be surely sealed.
  • the covering member 2 made of synthetic rubber or the like may be provided with a groove or two protrusions surrounding a circumference of the front face thereof, so that the covering member 2 is fixed to the panel 100 with the groove or the protrusions fitted into the opening 106 of the panel 100.
  • the portion where the cable is lead through the covering member may be sealed by packing instead of applying adhesive or filling material.
  • the covering member 2 may be bonded directly to the rear surface of the panel 100 without using a particular material as the sealing member 3.
  • the adhesive applied between the covering member 2 and the rear surface of the panel 100 functions as the sealing member 3.
  • the L-type fixtures 107' may be omitted.
  • the rear surface of the stationary connector 101 abuts on the rear wall 7 of the body 2b of the covering member 2, and the stepped portion between the flat cable 104 and the stationary connector 101 is caught in the groove 9 of the bottom cover 2b. Therefore, the stationary connector 101 is prevented from receding inside the panel 100, or easily fall off from the panel 100.
  • dust and oil coming through the opening of the panel to which the stationary connector is fixed, apertures of the stationary connector, and the gap thereof can be prevented from entering inside of an numerical controller or a machine tool and causing harmful effects on inside structure or electric circuits thereof.
