Definitions

  • the present invention relates to a wire end connector assembly for the connection of the wire with an equipment.
  • the internal combustion engine of a vehicle is provided with a distributor with which a spark coil or the like is connected via a high voltage resistive wire.
  • a distributor 1 is formed with a tubular receptacle 2 in the middle of which an externally threaded rod as a male terminal fitting 3 projects.
  • a female terminal fitting 5 is mounted at the end of a high voltage resistive wire.
  • a tubular seal member 6 is mounted at the end of the high voltage resistive wire such that the female terminal fitting 5 projects in the middle of the hollow space of the seal member 6.
  • the female terminal fitting 5 is connected with the male terminal fitting 3 while the seal member 6 is fitted into the receptacle 2.
  • the seal member made of rubber is easily deformable, the female terminal tends to be slanted or displaced from the center position, making it difficult to connect the female and male terminal fittings. Further, since the opening of the receptacle is sealed by the seal member before the female terminal fitting is connected with the male terminal fitting, the position of the male terminal fitting cannot be confirmed after an intermediate stage, making the connection even more difficult.
  • EP 0 602 698 A1 discloses an ignition cable assembly comprising a terminal attached to an end of a cable, a cable seal and a tower seal for enclosing a terminal, the cable seal insulating a portion of the terminal, the tower seal including an elastomeric boot radially spaced from a contact of the terminal for engaging sealingly an insulation tower of a mating terminal.
  • a connector is furthermore described in the preamble of claim 1.
  • EP 0 565 465 A1 discloses an electric connector in which the female terminal comprises an open inwardly tapered end-portion for accommodating a corresponding male terminal.
  • a wire end connector assembly comprising a first terminal fitting connected with a wire, a second terminal fitting disposed in a terminal chamber provided at or on an equipment, a seal member mounted on the end of the wire and at least one guide portion provided on the first terminal fitting for guiding the first terminal fitting substantially to a position where it is connectable with the second terminal fitting by coming into contact with an inner wall surface of the terminal chamber upon or during the insertion of the first terminal fitting into the terminal chamber, wherein the seal member is formed with the guide portion, wherein the terminal chamber has a substantially tubular shape and wherein the seal member and the guide portion have preferably concentric substantially tubular shapes and are substantially disposed along the same center axis as the terminal chamber at least in their connected state, and wherein the guide portion is formed into a hollow substantially tabular shape characterized in that the outer diameter of the guide portion is slightly smaller than the inner diameter of the terminal chamber; the guide portion has such a substantially tubular shape that it substantially covers the first terminal fitting; and the leading end of the guide portion is tape
  • a tubular shape according to the invention might have a substantially circular, elliptic, square or rectangular cross sectional shape.
  • the guide portion has such a substantially tubular shape that it substantially covers (i.e. it has at least the same longitudinal extension) the first terminal fitting and its outer surface preferably comes into contact with the inner wall surface of the terminal chamber when both terminal fittings are connected or are to be connected, and in particular acts as a seal member for sealing the opening of the terminal chamber, preferably watertight.
  • a clearance for permitting the deformation of the guide portion is defined substantially between the guide portion and the first terminal fitting.
  • the terminal chamber is formed by a substantially tubular wall projecting from the equipment, and preferably wherein the seal member comprises an outer sealing portion which is, in particular watertightly, substantially fitted to or on the outer surface of the tubular wall and/or an inner sealing portion which is, in particular watertightly inserted into the tubular wall, wherein in particular the inner and outer sealing portions are displaced with respect to each other along an insertion direction, in particular of the sealing portions into or on the tubular wall or along a connection direction of the terminal fittings.
  • the seal member is formed with an insertion hole into which the first terminal fitting connected with the wire is inserted, and/or a retaining portion for engaging the first terminal fitting to retain it in a specified or predetermined or predeterminable position.
  • the first terminal fitting comprises a securing portion with which the wire is to be connected and/or a connection portion with which the second terminal fitting is to be connected, and preferably wherein the guide portion is formed between the securing portion and the connection portion.
  • the guide portion is formed into a preferably hollow substantially cylindrical shape.
  • the wire end connector assembly has one or more seal portions or guide portion extending substantially in parallel to the first terminal fitting, wherein at least one seal portion is arranged in the radial direction between the first terminal fitting and the terminal chamber, the seal portion extending in particular substantially along the full or complete longitudinal extension or length of the first terminal fitting.
  • the sealing properties of the wire end connector are improved, in particular against the infiltration of moisture.
  • the sealing portion can serve also as a guide portion for substantially guiding the first fitting to a coupling position with the second fitting, thus providing according to the invention a double function of improved sealing and of improved connectability.
  • a wire end connection construction in which one of terminal fittings connectable with each other is connected with an end of a wire and the other terminal fitting is disposed in a terminal chamber formed at an equipment, the one terminal fitting is connected with the other terminal fitting by inserting the end of the wire into the terminal chamber through an opening of the terminal chamber, comprising:
  • the end of the wire is connected with the equipment by inserting the end of the wire into the terminal chamber formed at the equipment and connecting the one terminal fitting with the other terminal fitting.
  • the guide portion comes into contact with the opening edge of the terminal chamber, thereby guiding the one terminal fitting to the proper insertion position.
  • the one terminal fitting can be securely connected with the other terminal fitting by being guided to the proper insertion position.
  • the opening of the terminal chamber is sealed by the seal member.
  • the guide portion at the seal member, even if the one terminal fitting is displaced from its proper insertion position, it can be guided to and connected with the other terminal fitting. "Therefore, the terminal fittings can be easily and securely connected.
  • the terminal chamber has a tubular shape, and the seal member and the guide portion have preferably concentric tubular shapes and are disposed along the same center axis as the terminal chamber.
  • the guide portion and the seal member are displaced from the center axis of the terminal chamber, with the result that the guide portion comes into contact with the opening edge of the terminal chamber. Accordingly, while being inserted, the one terminal fitting is gradually guided to its proper insertion position, and the terminal fittings are securely connected. Simultaneously, the opening of the terminal chamber is sealed by the seal member.
  • the guide portion has such a tubular shape that it covers the one terminal fitting and its outer surface preferably, comes into contact with the inner wall surface of the terminal chamber when both terminal fittings are connected, and acts as a seal member for sealing the opening of the terminal chamber watertight.
  • the guide portion guides the one terminal fitting to its proper insertion position when the terminal fittings are connected, and seals the opening of the terminal chamber watertight after the terminal fittings are connected by coming into contact with the inner wall surface of the terminal chamber. Since the guide portion has a sealing function as well as a guiding function, it is not necessary to separately form the seal member. As a result, the construction of the guide portion can be simplified.
  • a clearance for permitting the deformation of the guide portion is defined between the guide portion and the one terminal fitting.
  • the guide portion which also acts as the seal member is deformed when coming into contact with the inner wall surface of the terminal chamber. Accordingly, an insertion force can be reduced, making the insertion of the guide portion into the terminal chamber easier. As a result, the terminal fittings can be easily connected while the terminal chamber is securely sealed.
  • the seal member comprises an outer sealing portion which is watertightly fitted to the outer surface of the tubular wall and the guide portion as an inner sealing portion which is watertightly inserted into the tubular wall.
  • the outer sealing portion is, in particular watertightly fitted to the outer surface of the tubular wall while the inner sealing is watertightly inserted into the tubular wall. Since the terminal chamber is sealed by both inner and outer sealing portions, a sealing performance can be enhanced.
  • the inner and outer sealing portions are displaced with respect to an insertion direction.
  • the inner and outer sealing portions are displaced with respect to the insertion direction, they are pressed against the tubular wall not simultaneously, but with a delay when the terminal fittings are connected. Accordingly, an insertion resistance can be reduced. Further, since the terminal chamber is sealed by both inner and outer sealing portions, a sealing performance can be enhanced.
  • the seal member is formed with an insertion hole into which the one terminal fitting connected with the end of the wire is inserted, and a retaining portion for engaging the one terminal fitting to retain it in a specified position.
  • the one terminal fitting can be retained by the retaining portion of the seal member. Accordingly, the one terminal fitting does not wobble when the terminal fittings are connected, thereby making the connection of the terminal fittings easier.
  • This wire end connection construction is adapted to connect an end of a high voltage resistive wire with e.g. a distributor or a spark coil in the internal combustion engine of a vehicle.
  • this connection construction is provided with a male terminal fitting 11 and a female terminal fitting 12 which are connectable with each other.
  • the male terminal fitting 11 is disposed in a receptacle 15 projecting from a side surface of a casing 14 of a distributor 13.
  • the receptacle 15 has a tubular shape, and the inner diameter thereof is considerably larger than the diameter of the male terminal fitting 11.
  • the male terminal fitting 11 is an externally threaded rod, and projects along a center axis of the receptacle 15 by such a distance that the leading end thereof is located slightly inward of an opening edge 15a of the receptacle 15. Through unillustrated, the male terminal fitting 11 is connected with a distribution circuit within the distributor 13.
  • the female terminal fitting 12 is connected with an end of a wire 16.
  • the female terminal fitting 12 includes a barrel portion 17 and a connection portion 18 formed at the leading end of the barrel portion 17 and engageable with the male terminal fitting 11.
  • the barrel portion 17 includes one or more, in particular three pairs of deformable portions 19 along its longitudinal direction. After the end of the wire 16 is placed on the barrel portion 17, the deformable portions 19 are bent to retain the wire 16, thereby connecting the end of the wire 16 with the barrel 17.
  • the leading end of each deformable portion 19 is serrated like saw teeth, so that it cuts in the insulation coating of the wire 16 when being bent, thereby making the connection more secure.
  • connection portion 18 is formed by bending a metal strip into a hollow cylindrical shape extending along the longitudinal direction, and the inner diameter thereof is substantially equal to the outer diameter of the male terminal fitting 11.
  • a C-shaped elastic member 20 is fitted on the leading end of the connection portion 18 to join a seam formed when the metal strip is bent.
  • the elastic member 20 applies a biasing force to narrow the opening of the connection portion 18, and the male terminal fitting 11 is pressed into the narrowed opening of the connection portion 18.
  • a stopper wall 25 is formed by bending the material. When the wire 16 is connected, the leading end thereof comes into contact with the stopper wall 25 to be positioned.
  • a seal member 21 of insulating and/or sealing material, e.g. of rubber is mounted on the end of the wire 16.
  • a sealing tubular portion 22 fittable to the outer surface of the receptacle 15.
  • the sealing tubular portion 22 has an inner diameter slightly smaller than the outer diameter of the receptacle 15, and is watertightly fittable to the receptacle 15.
  • a through hole 23 is so formed as to extend from the rear end surface of the seal member 21 to the inside of the sealing tubular portion 22.
  • the rear part of the through hole 23 has a diameter slightly smaller than the that of the wire 16, and the front part thereof is formed to have a slightly larger diameter (slightly smaller than the barrel portion 17) than that of the rear part, thereby forming a retaining portion 26.
  • the barrel portion 17 of the female terminal fitting 12 connected with the wire 16 is fitted into the retaining portion 26 through the through hole 23, with the result that the female terminal fitting 12 is retained with the connection portion 18 projecting into the sealing tubular portion 22.
  • a guide portion 24 projects such that it coats the outer surface of the female terminal fitting 12.
  • the guide portion 22 has a tubular shape, and the outer diameter thereof is slightly smaller than the inner diameter of the receptacle 15.
  • the leading end of the guide portion 24 is tapered to form a guide surface 24a. More specifically, when the female terminal fitting 12 is inserted into the receptacle 15 while being displaced from its proper insertion position (center axis of the receptacle 15), the guide surface 24a comes into contact with the opening edge 15a of the receptacle 15, thereby guiding the female terminal fitting 12 to the proper insertion position.
  • An opening edge 22a of the tubular portion 22 is also tapered to make it easier to fit the tubular portion 22 on the receptacle 15.
  • the female terminal fitting 12 is inserted into the receptacle 15 while the seal member 21 is fitted on the receptacle 15.
  • the guide surface 24a of the guide portion 24 comes into contact with the opening edge 15a of the receptacle 15. Accordingly, while being pressed into the receptacle 15, the female terminal fitting 12 is guided to its proper insertion position, and consequently connected with the male terminal fitting 11.
  • the terminal fittings 11, 12 are securely connected, and the opening of the receptacle 15 is sealed watertight (see FIG. 3).
  • the terminal fittings 11, 12 can be securely connected even if the female terminal fitting 12 is obliquely inserted while being displaced from its proper insertion position. In other words, since the terminal fittings 11, 12 can be securely connected only by inserting the female terminal fitting 12 into the receptacle 15, the connection can be very easily made. Further, since the female terminal fitting 12 can be retained by the retaining portion 26 of the seal member 21, the female terminal fitting 12 does not wobble when the terminal fittings 11, 12 are connected. As a result, the connection can be more easily made.
  • a guide portion of the second embodiment has a tapered projected portion formed at its leading end.
  • a guide portion 31 is formed such that its outer diameter is slightly smaller than the inner diameter of a receptacle 32, a front part of its outer surface projects more outward than a base part, and this projected portion 33 is tapered toward the leading end of the guide portion 31.
  • the outer diameter of the projected portion 33 is slightly larger than the inner diameter of the receptacle 32 so that, when the guide portion 31 is inserted into the receptacle 32, the projected portion 33 is compressed to be in close contact with the inner wall surface of the receptacle 32.
  • the projected portion 32 is tapered, there is formed a guide surface 33a.
  • the terminal fittings 34, 35 can be easily and securely connected as in the first embodiment. Further, as the terminal fittings 34, 35 are connected, the opening of the receptacle 32 is sealed watertight by both the sealing tubular portion 22 and the projected portion 33, further enhancing a sealing performance.
  • a sealing tubular portion 61 has a short depth as shown in FIG. 5 and can cover only the leading end of the receptacle 32 in this embodiment. Since the other construction is similar or same as that of the second embodiment, no description is given by identifying the corresponding or same elements by the same reference numerals.
  • the projected portion 33 is inserted into the receptacle 32 while being compressed and then the sealing tubular portion 61 is fitted to the outer surface of the receptacle 32. Accordingly, the projected portion 33 and the sealing tubular portion 61 are not simultaneously pressed against the receptacle 32, thereby reducing an insertion resistance. Further, since the opening of the receptacle 32 can be sealed by both the sealing tubular portion 61 and the projected portion 33, a sealing performance can be further enhanced.
  • the elastic member 20 fitted on the female terminal fitting 34 is in close contact with the inner surface of the projected portion 33 in the second embodiment, the inner surface of a projected portion 72 formed at the leading end of a guide portion 71 is cut away over the entire circumference to form a clearance 73 between the inner surface of the projected portion 72 and the elastic member 20 as shown in FIGS. 6 and 7 in this embodiment. Since the other construction is similar or same as that of the second embodiment, no description is given by identifying the corresponding or same elements by the same reference numerals.
  • the projected portion 72 is deformed if it comes into contact with the opening edge 32a of the receptacle 32 when the terminal fittings 34, 35 are connected, and inserted into the receptacle 32 while guiding the female terminal fitting 34 to its proper insertion position. Accordingly, a force for inserting the guide portion 71 into the receptacle 32 can be reduced, with the result that the terminal fittings 34, 35 can be easily connected and the opening of the receptacle 32 can be easily sealed.
  • the inner surface of a projected portion 82 formed at the leading end of a guide portion 81 is serrated over the entire circumference to form a clearance 83 between the inner surface of the projected portion 82 and the elastic member 20 as shown in FIG. 8 in this embodiment.
  • the clearance 83 is interrupted in the circular direction by projections 82a, which extend inwardly from the projected portion, being in particular unitarily or integrally formed therewith, toward the C-shaped elastic member 20, thus forming a star-like configuration. Since the other construction is similar or same as that of the second embodiment, no description is given by identifying the corresponding or same elements by the same reference numerals.
  • the projected portion 82 is deformed if it comes into contact with the opening edge 32a of the receptacle 32 when the terminal fittings 34, 35 are connected, and inserted into the receptacle 32 while guiding the female terminal fitting 34 to its proper insertion position. Accordingly, similar to the fourth embodiment, a force for inserting the guide portion 81 into the receptacle 32 can be reduced. Further, since the inner surface is serrated, the opening of the receptacle 32 can be sealed while preventing the strain caused by the compression of the projected portion 82.
  • a guide portion 41 of the sixth embodiment has a bulging portion 42 formed at its leading end.
  • a guide portion 41 is formed such that its diameter is slightly smaller than the inner diameter of the receptacle and a leading part of its outer surface bulges outward over the entire circumference.
