Definitions

  • This invention relates to a housing assembly for use in a water seal connector.
  • a sealed electrical connector is shown in EP-A-0072104.
  • This connector includes a sealing member having holes through which conductors pass, the holes being arranged in a pattern to correspond with passageways in the connector.
  • US-A-3784959 shows registration of a hard dielectric member with a connector casing using pins, but does not address the problem of deformation of a soft sealing member when connectors are inserted.
  • a housing assembly for use in a water seal connector, comprising: a readily deformable rubber bush having a through hole for inserting a contact therethrough, and a housing for defining a cavity therein for receiving and sealably holding said rubber bush; wherein said housing has at least one hole at the bottom of said cavity arranged to be in alignment with said hole in said bush, said hole being adapted to receive and hold said contact; said cavity has a plurality of projections on a surface of the bottom thereof; and said rubber bush has a plurality of recesses on a side surface thereof adjacent to the surface of the bottom, said recesses co-operating with said projections to prevent distortion of said hole in said bush and thereby maintain the alignment of said hole with the hole in said housing when the contact is inserted through the through hole of said rubber bush.
  • the water sealed connector as shown in Figure 1, comprises multiple, generally tubular bodied receptacle contacts (10) terminating to a wire (100); multiple plug housings (20) housing the receptacle contacts; a cap housing (30) equipped with multiple pin contacts (200) that electrically connect with the receptacle contacts and receive the multiple plug housings.
  • housing holes (21) have been drilled to hold the multiple receptacle contacts in place.
  • multiple pin contacts have been placed in an arrangement so as to be in alignment with receptacle contacts inside the cavity (31) designed to accept the plug housing.
  • Each receptacle contact is maintained in place in the housing hole (21) after insertion through the through hole (41) of the rubber bush (40) that is fixedly inserted into the plug housing.
  • Pin contacts protrude after insertion through the bottom of the cavity of the cap housing.
  • the protrusions form a terminal and connect to a printed circuit board, for example.
  • Figure 2 is a cross-section of the connected plug housing and cap housing, showing receptacle and pin contact, establishing electrical flow.
  • the receptacle contact connects at its tip with the ferrule (sleeve) (14) to form a stepped portion (13).
  • the ferrule engages with a lance-shaped member (22), a pair of top and bottom spear-shaped projections being disposed in the housing hole.
  • the stepped portion (13) is formed in one of two alternatives. One is to bend back the top area of the contact itself. The other is to enlarge the material of the end tip of the contact.
  • the lance (22) has a spear-like shape, with its tip a free end terminal along the part of the side wall of the housing hole towards the shaft direction of said hole.
  • the lance tip engages with the stepped portion of the ferrule and serves to hold the receptacle contact inside the housing hole.
  • a rubber bush (40) preferably composed of heat resistant silicone rubber penetrated with oil to reduce insert resistance is provided.
  • the side wall of the rubber bush has a number of integral ridges (43) that function as seal rings to provide sealing.
  • multiple projections (24) are disposed at the bottom of the cavity (23) of the plug housing which accepts the rubber bush (40). As will be mentioned later, these projections facilitate easy insertion of the contacts into through holes.
  • FIG. 6 represents a rubber bush with recesses for contact with projections, as shown.
  • the projections are arranged in a regular pattern around the contact holes.
  • such pattern is not always necessary.
  • the height of the projections need not be uniform, but may vary.
  • the recesses in the rubber bush are not limited in number or in depth. Recesses without corresponding projections can be provided as well.
  • the numeral (25) represents a locking spring built into the top of the plug housing.
  • the locking spring composed of metal, is designed in the shape of an "s" as shown in Figure 2.
  • One side of the "bent” end (25b) is designed to be fitted into the groove (26) built into the top of the housing.
  • the other "bent" end of the locking spring (25a) functions as a handle.
  • Both sides of the locking spring are flanked by guiding walls (28). These are designed to eliminate problems such as wires interfering with the spring when inserting the plug housing into the cap housing.
  • the guiding walls function to determine the insert direction of the plug housing, eliminating any mistakes in insertion direction.
  • the height of these guiding walls is higher in the area of the handle.
  • the guiding walls likewise, efficiently prevent wire tangle even though the distance for the spring snap back is considerable.
  • the numeral (50) represents a seal ring, preferably composed of heat resistant silicone rubber and coated with oil in the fashion as the rubber bush.
  • Figure 3 presents a exploded view of the cap housing, with multiple pin contacts arranged alternately in a staggered pattern of three rows. As shown in Figure 3, each pin contact protrudes from a through capacitor (33). One side of the pole of the through capacitor is soldered onto the grounding plate (34) that covers the back of the cap housing. This capacitor functions as a filter to prevent external electrical noise.
  • Element (35) functions to align the leads of the pin contacts, as is well known.
  • Figure 4A and Figure 4B show an example of receptacle contact in the usage of this invention.
  • Numeral (10a) shows the generally tubular conductive main body.
  • the main body is tubular to facilitate insertion of the contact with ease.
  • the design also allows for a more dense concentration of contacts within the housing.
  • Numeral (11) is a means to electrically connect the wire to the connector.
  • the wire is fixed by pressure, such as crimping.
  • the main body of contact (10a) and the means (11) have a tapered area to facilitate removal of the contact from a housing hole.
  • connecting device (12) is a connecting device for terminals and pins such as on printed circuit board or similar connections.
  • connecting device (12) comprises at least a pair of leaf springs with free ends defined by a groove along the direction of the main core shaft of the mainbody. The tips of the pair of leafsprings are staggered towards each other as shown in Figure 4A.
  • the pin contacts receptacle contact in two steps, facilitating insertion. Even if the pin is not aligned with the spring, the spring will still receive the pin. Furthermore, it will eliminate permanent distortion of the spring due to over stress of the spring.
  • Numeral (14) represents the ferrule (sleeve) covering the tip of the main body.
  • the corner, namely the tip of the ferrule, is beveled, as shown in Figure 4A, so as to minimize damage to the rubber bush (40) when inserting the contact into the through hole (41).
  • the ferrule has a notch (14a) on its side wall designed to position it to the main body.
  • the ferrule being of material different from the mainbody material, functions to strengthen the tip of the contact mainbody.
  • the stepped portion (13) made by the ferrule and the mainbody serves as a stopping device for the lance set up in the housing hole of the housing.
  • the projections, set at the bottom of the cavity of the housing accepting the rubber bush function so as to prevent distortion of the holes when the contact end of the wire is inserted through the through hole of rubber bush. Consequently, the contact is easily inserted into the through hole despite the arrangement of the holes or the size of the wire to be connected. As a result, less effort is required. Accordingly, the preferred embodiments are provided in an illustrative rather than in a limiting sense, the true scope of the invention being set forth in the claims appended hereto.
