Definitions

  • the present invention relates to an electric connector. More particularly, the present invention relates to an electric connector whose coupling with a counterpart connector is facilitated by a latch portion.
  • Fig. 18 is an exploded perspective view of a related art electric connector
  • Fig. 19 is a sectional view of the electric connector of Fig. 18 in the assembled state.
  • the electric connector 50 set forth in JP-A-2005-123102 includes: a plurality of pins 51; a connector housing 52 in which the pins 51 are housed; a rear holder 55 that is installed to the rear portion of the connector housing 52 and has a plurality of through-holes through which the pins 51 are inserted; a sealing member 54 that is interposed between the connector housing 52 and the rear holder 55; and a manipulation lever 53 and rear cover 56 that are fitted to the rear portion of the connector housing 52.
  • the connector housing 52 is provided with a rail 52 A that extends in the horizontal direction
  • the rear cover 56 is provided with a guide slot 56 A into which the rail 52 A is inserted.
  • a guide slot 56 A is also provided in the bottom wall of the rear cover 56 in Fig. 18 .
  • these guide slots 56 A , 56 A are each provided with a rear holder pressing portion 56 B , 56 B , these rear holder pressing portions 56 B , 56 B being composed of a level portion 57 that contacts against the rear surface of the rear holder 55, and an inclined portion 58 that slides over the edge of the rear face of the rear holder 55.
  • the rear cover 56 is mounted to the connector housing 52 by being slid horizontally onto the rear portion of the connector housing 52. More precisely, the guide slots 56 A , 56 A of the rear cover 56 are mounted onto the upper and lower rails 52 A , 52 A of the connector housing 52, then the rear cover 56 is fitted by being slid onto the rear portion of the connector housing 52. By means of such sliding motion, the rear holder pressing portions 56 B , 56 B of the rear cover 56 contact with and are pressed against the rear portion of the rear holder 55. As a result, the rear holder 55 is moved toward the fixed position on the connector housing 52, while clamping the seal member 54 between itself and the rear portion of the connector housing 52.
  • the inclined portions 58 contact against the rear surface edges of the rear holder 55, so that the rear holder 55 slides along the sloping surfaces of the inclined portions 58 and is moved toward the rear portion of the connector housing 52. Then the inclined portions 58 move beyond the rear surface edges, and the level portions 57 contact with the rear surfaces of the rear holder 55. Thereby, the pressed state is maintained, and watertightness is preserved between the outer surfaces of the electric wire portions of the wired pins 51 that were installed earlier and the sealing member (see Fig. 19 ).
  • the sliding of the rear cover 56 results in the rear holder 55 being fixed to the connector housing 52, and simultaneously in the sealing member 54 being clamped, so that watertightness is preserved between the outer surfaces of the electric wire portions of the wired pins 51 and the sealing member 54.
  • guide slots 56 A and rear holder pressing portions 56 B are provided in the rear cover 56, and horizontally-extending rails 52 A are provided on the connector housing 52; by mounting the guide slots 56 A in the rear cover 56 onto the rails 52 A on the connector housing 52, and sliding the rear cover 56 onto to the rear portion of the connector housing 52, the rear holder 55 is fixed to the connector housing 52, and at the same time the sealing member 54 is clamped, so that watertightness exists between the outer surfaces of the wired pins 51 and the sealing member.
  • the rails 52 A that are provided on the connector housing 52 are formed as strip protrusions that project from the outer walls of the connector housing 52, because of which, limits are placed on the mechanical strength.
  • JP-A-2005/123102 as connector assembly is described which is aimed at waterproofing a terminal with a wire from an insertion side.
  • An advantage of some aspects of the invention is to provide an electric connector that can proactively detect misassembly of the connector components when the rear cover is fitted.
  • Another advantage of the present invention is to provide an electric connector that can determine the mounting status of the sealing member, and the joining status of the connector housing and rear holder, when the rear cover is fitted.
  • an electric connector includes: a connector housing inside which pins are housed, and which has at the front an insertion portion into which a counterpart connector is inserted, and at the rear a holder mounting portion; a sealing member that is mounted onto the outer periphery of the holder mounting portion; a rear holder the front end portion of which is a contacting surface for contacting with the sealing member; which has at the front a mating cavity that is fixed onto the holder mounting portion, and at the rear a cover installation portion; and which is fixed to the connector housing with the sealing member interposed; and a rear cover which is mounted to the cover installation portion via sliding motion.
  • the electric connector incorporates the features that a latching portion is provided in location adjacent to the cover installation portion at the rear of the rear holder, an engaging portion into which the latching portion engages are provided in the holder mounting portion of the connector housing, and if the latching portion is in a state of non-engagement with the engaging portion when the rear holder is mounted to the connector housing, the sliding motion of the rear cover is blocked.
  • the latching portions and engaging portions may preferably be provided in locations on the rear holder and the holder mounting portion, respectively, that are opposite each other.
  • the latching portions may preferably be constituted of a latching member possessing resilience and formed on part of the outer wall of the rear holder, the latching member may preferably have a latching bar and projecting block, and the engaging portion may preferably have a latching slot that is formed in the wall of the connector housing, so that if the connector housing and rear holder are not completely fixed together and the latching portion do not engage onto the engaging portion, then, just before latching into the latching slot, the latching bar will run up the connector housing's wall, with the result that the latching member will be pushed upward, and consequently the projecting block will block the rear cover from being mounted via sliding motion onto the cover installation portion.
  • part of the outer wall of the rear holder may preferably be formed as a double wall constituted of an inner plate and an outer plate with a gap therebetween, and the latching portion may preferably be provided on the inner plate.
  • a manipulation lever one portion of which latches into the counterpart connector to effect coupling of the two connectors may preferably be mounted to the wall of the rear holder.
  • a latching portion and an engaging portion are provided at the rear of the rear holder and in the holder mounting portion, respectively, and if the latching portion fails to engage with the engaging portion when the rear holder is fitted into the connector housing, so that a non-engaged state results, then sliding motion of the rear cover at the cover installation portion will be blocked by the latching portion.
  • the sealing member and joining of the connector housing and rear holder be incomplete, it will not be possible to mount the rear cover. Consequently, during mounting of the rear cover it is possible to sense whether the sealing member, and the connector housing and rear holder, have been fully mounted, and hence to proactively detect incomplete assembly of the connector.
  • providing the latching portion and the engaging portion in locations on the rear holder and the connector housing, respectively, that are opposite each other, will enable the rear holder to be fixed to the connector housing by means of the latching portion and engaging portion, which will be opposite each other, so that engagement of the rear holder to the connector housing will be stable and firm.
  • the latching portion and engaging portion can be formed in a simple manner by machining the outer wall of the rear holder and the wall surface of the connector housing.
  • the rear cover can be fitted by being slid into the gap between the inner wall plate and outer wall plate, and therefore can be fitted stably without being exposed to the exterior. Further, the manipulation lever for effecting coupling of the two connectors can also be fitted in the gap between the double walls.
  • the fact that the manipulation lever is fitted to the rear holder facilitates coupling with the counterpart connector.

  • the connector housing 3 usually houses the pins and their accessories, etc., and therefore has a complex structure, so that providing the above-mentioned latching portion, etc., on the connector housing 3 would render the structure thereof even more complex, whereas it is a simple matter to form the housing latching portion LA, etc., on the rear holder 6 since few other parts are mounted thereon.
  • housing latching portion LA cover mounting portion RC
  • lever mounting portion LB lever mounting portion LB

  • the opening 26 serves as a lead-out hole that leads the lead wires out to the exterior.
  • the gap 25 between the pair of sidewalls 21, 21 serves as an insertion opening for insertion of the rear wall 6 2 of the rear holder 6. Since both sidewalls 21, 21 have the same structure, the description below will deal with one sidewall only.
  • the sidewall 21 is formed with a thick edge, and in this thick edge there is formed a flat-bottomed slot 22 0 enclosed by opposed first and second sidewall portions 22 A , 22 B . More precisely, the flat-bottomed slot 22 0 has opposed first and second sidewall portions 22 A , 22 B of which one, the first sidewall portion 22 A , constitutes part of the sidewall 21, and the other, the second sidewall portion 22 B , constitutes part of the inner wall. Roughly at the longitudinal center of the outer face of the first sidewall portion 22 A there is formed a latching projection 22c that projects upward. This latching projection 22c is formed as a roughly square-shaped low-profile projection.

  • the manipulation lever 30 is mounted to the rear holder 6 so as to turn freely, but the axle 33 A is provided with a turn restricting portion 33 A , that restricts such turning.
  • this turn restricting portion 33 A' is of a teardrop shape, such that its cross-section, supposing the axle 33 A to be cut through in a plane orthogonal to the direction in which the axle 33 A rises up from the lever arm 31, has flat edges 33 A1 and a circular edge 33 A2 .
  • the flange 33 B is in the shape of a disc with a cut-off portion 33 B' at the edge, and is of a size that enables insertion into the receiving hole 10 A .
  • the provision of the cut-off portion 33 B' facilitates installation to the receiving hole 10 A .
  • the pair of first and second cam slots 36, 37 are formed on the side that faces in the opposite direction to the pivot projection 33's direction of insertion. These cam slots 36, 37 are formed by further reducing the thickness of the lever arm 31 past the step difference portion 31c. More precisely, the first cam slot 36 has: a guide face 36 A over which the latching projection 22c of the rear cover 20 slides; a first stopper 36 1 against which the latching projection 22c contacts; and a latching slot 36 B into which the latching projection 22c latches, the first stopper 36 1 and latching slot 36 B being formed as a part of the step difference portion 31c.

  • This connector 1 is assembled via the following processes: (I) sealing member mounting process, (II) holder joining process, (III) pin mounting process, (IV) TPA mounting process, (V) lever mounting process, and (VI) rear cover mounting process.
  • the sealing member 35 is mounted over the outer surface of the coupling portion 3 B of the connector housing 3 until contact is made with the rib 3 0 , these items being among the connector components shown in, for example, Figs. 1 and 2 .
  • the sealing member 35 is mounted as far as the position where it contacts the rib 3 0 , the inner periphery of the sealing member 35 fits tightly against the outer periphery of the connector housing 3, enabling mounting of the rear holder 6.
  • Mounting of the sealing member 35 effects a watertight sealing between the housing connector 3 and rear holder 6 to be described later.
  • the coupling portion 3 B of the connector housing 3 is inserted into the rear holder 6.
  • the latching bar 11 B of the latching portion 11 is sunk into the latching groove 5 A and engages into the mating cavity 6C.
  • the rear holder 6 is thereby latched and fixed to the connector housing 3.
  • the large pins 2 A and the cluster of small pins 2 B are inserted from the rear of the rear holder 6 through the through-holes 4 A and 4 B , respectively, in the connector housing 3, and thereby both sets of pins are housed and fixed inside the connector housing 3 with the rear holder 6 mounted thereto.
  • the TPA 38 is inserted into the mounting hole 5 B in the connector housing 3, fixing the female pins 2 inside the connector housing 3.
  • the edges of the flanges 33 B , 33 B enter into the gaps 6 G , 6 G between the inner and outer plates 6 A , 6 B , becoming undislodgeable therefrom, and the manipulation lever 30 is installed in a freely turnable state relative to the rear holder 6.
  • the flanges 33 B , 33 B will not be dislodged even if subjected to an external force opposite to that exerted when the manipulation lever 30 was pushed in. This means that after being mounted to the rear holder 6, the manipulation lever 30 will not become detached therefrom even if an impact or other strong external force should act on the manipulation lever 30.
  • a gap G (see Fig. 13B ) into which the first sidewall portion of the rear cover 20 will be pushed is formed between the lever arms 31, 31 of the manipulation lever 30 and the inner plates 6 B , 6 B of the rear holder 6.
  • This gap G is composed of a first gap G 1 that is opposite the guide surface 36 A of the manipulation lever 30, and a second gap G 2 that is opposite the inner wall 31 B , the first gap G 1 being wider than the second gap G 2 .
  • the rear cover 20 is installed to the rear holder 6.
  • the rear cover 20 is positioned at the part of the connector housing 3 indicated by arrow A 1 in Fig. 13A , that is, on the side where the manipulation lever 30's connecting piece 32 is located, and the rear cover 20 is inserted in the direction of the first gap G 1 between the rear holder and the manipulation lever 30.
  • Such insertion is effected along the direction of one of the mounting portions 12 A , so that one of the support projections 7 A will be inserted into the flat-bottomed slots 22 0 , 22 0 of the rear cover 20.
  • the rear cover 20's guide rails 23, 23 will be inserted along the rail projections 6 2A , 6 2A .
  • Figs. 11 and 12 are explanatory views illustrating the misassembly, and correspond to Figs. 9 and 10 respectively.

  • Such pushing-on of the rear holder 6 brings the front wall 6 1 surface of the rear holder 6 into contact with an edge face of the sealing member 35. If the rear holder 6 is incompletely pushed in at this point, then due to the resilience of the latching arm 11 A , the latching bar 11 B of the latching portion 11 will climb on top of the sidewall portion 5 A' of the latching groove 5 A , and the projecting block 11 C will be lifted upward (see Fig. 11C ).
  • the pair of opposed sidewalls 21, 21 have identical structure, which might pose a risk of the rear cover 20 being mounted in the direction of arrow A 2 in Fig. 14A . If the rear cover 20 were mounted in that direction, the manipulation lever 30 could not be manipulated. Accordingly this connector 1 is so contrived that it is not possible to mount the rear cover 20 in the direction of arrow A 2 . More precisely, if the rear cover 20 is mounted to the rear holder 6 in the direction of arrow A 2 in Fig.
  • the first sidewall portion 22 A of the rear cover 20 will enter inside the second gap G 2 , and although the entrance of the second gap G 2 is rendered large by the presence of the manipulation lever 30's second cam slot 37 at such opening, the second cam slot 37's length is less than the width of the first cam slot 36, so that when the rear cover 20 is pushed in further, the latching projection 22c on the sidewall 22 A surface will collide with the step difference portion 31 C' that serves as second stopper, and any further pushing-in of the rear cover 20 will be blocked. In this way, mounting of the rear cover 20 in the direction of arrow A 2 is rendered impossible.
