Definitions

  • This invention relates to an electric connector, and more particularly to a multi contact connector including a plurality of contacts each having a contact support structure for supporting a contact in an insulating housing.
  • contacts are in general inserted and fixed in fixing apertures formed in an insulating housing with a predetermined intervals.
  • a contact A for example as shown in a perspective view of Fig. 1 includes a curved contact element 1 having at one end a ratch turn-up portion la, and a terminal element 2 adapted to be soldered having a U-shaped section including two sidewalls 2a.
  • an insulating housing B is formed for example as shown in a plan view and a sectional view of Figs. 2a and 2b.
  • the insulating housing B includes support grooves 3a formed in both sides of an upper end of an insulating wall 3 for supporting the ratch turn-up portions la of the contacts A and an insertion positioning flange 4 integrally formed with the insulating wall 3 for positioning a mating connector whose contacts are to be connected to this contacts A.
  • the insertion positioning flange 4 has contact fixing apertures 5 spaced apart from each other by a predetermined distance between two contacts A.
  • the terminal element 2 of the contact A is inserted into the contact fixing aperture 5 so that the ratch turn-up portion la is in the support groove 3a and simultaneously the ratch projections 2b abut against the ratch protrusion 5a as shown in Fig. 3.
  • a fixing tool (not shown) is inserted into the terminal element 2 from its one end remote from the contact element and the fixing piece 2c is raised away from the insulating wall 3 so that the ratch projections 2b and the fixing piece 2c of the contact A are anchored at the ratch protrusion 5a to hold the contact A in the housing B.
  • an insulating housing B has insulating walls 3 on both sides and a mating connector insertion aperture 5.
  • Each the insulating wall 3 is formed in a front end with a support groove 3a for the ratch turn-up portion la.
  • a bottom of the mating connector insertion aperture 5 is formed on both sides with contact fixing apertures 5 each having a ratch protrusion 5a.
  • the contact A is fixed in the insulating housing B.
  • the process for inserting a number of contacts one by one into fixing apertures of an insulating housing is complicated to increase the cost of the connector. It is therefore desirable for automatic assembling and low cost to form a required number of contacts A in a unitary body connected by connecting pieces 6 as shown in a perspective view of Fig. 5, thereby enabling the unitary contacts to be inserted and fixed in the fixing apertures of the insulating housing.
  • the unitary contacts also makes it possible to transfer the contacts continuously into a plating apparatus for the contacts, so that the unitary contacts can be partially plated shown at dotted portions in Fig. 5. Accordingly, the construction of the unitary contacts before assembling is desirable for saving plating materials.
  • the fixing aperture 5 should be sized to receive the terminal element 2 of the contact with the minimum clearance without play.
  • the contact is often provided with elongately extending lugs 7a for crimping lead wires to form a crimping terminal element as shown in Fig. 6a. Accordingly, the crimping terminal element could not be inserted into the insulating housing, because the extending lugs obstruct the terminal element from passing through the fixing aperture 5 which has been formed exactly with respect to the terminal element without play. As the result, it should be required to insert through the contact fixing apertures the lead wires one by one in a direction shown by an arrow in Fig. 6b after the extending lugs have been bent or crimped on the lead wires to eliminate the above obstruction. This fixing operation of the contacts to the insulating housing is very troublesome.
  • an electric connector includes at least one elongated contact and an insulating housing for receiving the elongated contact therein; said elongated contact comprises at one end a curved contact element having at a front end a support piece extending in a longitudinal direction of said contact, at the other end a terminal element, and an elastic fixing lug integral with said contact and supported at one end on a side of said curved contact element by the contact at an intermediate portion thereof between the curved contact and terminal elements, said elastic fixing lug extending in parallel with said terminal element but progressively extending with the other end not supported by the contact away from a surface of the contact on the same side as that of the curved side of said curved contact element with respect to said surface of the contact; and said insulating housing comprising at least one support groove opening in a direction of insertion of a mating connector and formed in a front end of an insulating wall for receiving said support piece of said contact, a lug detaching aperture for receiving said elastic fixing lug of said
  • the lug detaching aperture diverges to facilitate accessing the elastic fixing lug after assembling the contact in the insulating housing. It is advantageous to insert a tool into the lug detaching aperture to deform the elastic fixing lug so as to dislodge the lug from a bottom of the lug detaching aperture. In this manner, the contact connected with a lead wires is removed for correction of misarrangement of the wire and the change of circuits.
  • the insulating housing including a plurality of contacts comprises the insulating wall in the form of a rectangular shape having the support grooves equal in number to the contacts on both sides respectively in one row and an insertion positioning flange, and the insertion positioning flange is formed on both sides and on a side of the support grooves with the lug detaching apertures equal in number to the support grooves respectively in one raw and on both sides and on an opposite side of the support groove with the contact fixing apertures equal in number to the support grooves, respectively in one row thereby forming a male connector.
  • the insulating housing including a plurality of contacts comprises the two insulating walls in the form of rectangular shape having the support grooves equal in number to the contacts respectively in one row and an insertion positioning flange common to and connecting the two insulating walls, and the insertion positioning flange is formed on both sides and on a side of said support grooves with the lug detaching apertures equal in number to the support grooves, respectively in one row, and on both sides of the flange and on an opposite side of the support groove with the contact fixing apertures equal in number to the support grooves respectively in one row, thereby forming a female connector.
  • a contact A comprises a curved contact element 1 having at its front end a support piece 8 and extending in a longitudinal direction of the contact and a terminal element 2 having an elastic fixing lug 9 in parallel with the terminal element.
  • the elastic fixing lug 9 is in the form of a substantially elongated rectangular shape in parallel with the longitudinal direction of the contact and a short side or edge of the rectangular shape on the side of the terminal element is substantially perpendicular to the longitudinal direction. However, the portion of the elastic fixing lug 9 rises progressively away from the surface of the contact.
  • the elastic fixing lug 9 is supported at its supported portion 9b on the side of the contact element by a support member 9a which is formed by bending a part of the contact substantially perpendicularly to the surface of the contact between the curved contact element 1 and the terminal element 2.
  • an insulating housing B is formed at a front end of its insulating wall 3 in the form of a rectangular shape with support grooves 10 opening in directions of insertion of a mating connector for supporting the support pieces 8 of contacts A and formed with an insertion positioning flange 4 integral therewith.
  • the insertion positioning flange 4 is formed with contact fixing apertures 5 which are so dimensioned as to permit the supported portions 9b of the elastic fixing lugs 9 supported by the support members 9a of the contacts to pass therethrough without large clearances.
  • the insertion positioning flange 4 is moreover formed with lug detaching apertures 11 opening or diverging to the side of the support grooves 10 for inserting a tool into directions shown by arrows in Fig. 8.
  • the support pieces 8 When the contacts A are inserted with their support pieces 8 preceding into the insulating housing B from the bottom as viewed in Fig. 9, the support pieces 8 first start to enter the support grooves 10 of the housing. With further insertion of the contacts, the elastic fixing lugs 9 are urged toward the insulating wall 3 by walls of the contact fixing apertures 5 until the support pieces 8 have completely entered the support grooves 10. When the support pieces 8 have completely entered the support grooves 10, the elastic fixing lugs 9 are released from the contact fixing apertures 5 and snap outwardly into the lug detaching apertures 11, thereby fixing the contacts A in position to the insulating housing B.
  • the contacts A can be fixed to the insulating housing B by inserting the contacts A with their support pieces preceding into the fixing apertures 5 of the housing B.
  • a connecting piece 6 can be provided on the sides of terminal elements of the contacts as shown in Fig. 10, instead of the sides of contact elements as shown in Fig. 5.
  • a number of contacts A connected by the connecting piece 6 are simultaneously inserted into a number of contact fixing apertures of the insulating housing B, and then the connecting piece 6 is removed from the contacts A by cutting along a dot line in Fig. 10.
  • This arrangement of the contacts shown in Fig. 10 facilitates the partial plating of the contacts to lower the manufacturing cost.
  • the elastic fixing lugs 9 of the contacts when the elastic fixing lugs 9 of the contacts have passed through the contact fixing apertures 5 of the insulating housing, the elastic fixing lugs 9 freely snap outwardly to fix the contacts in position in conjunction with the support pieces 8 in the support grooves 10 of the housing. Accordingly, there is no risk of the undue deformation of the contacts causing poor connection between the contacts of connector, due to the use of the tool required in the prior art above described. According to the invention, moreover, in removing the contacts from the insulating housing, the elastic fixing lugs 9 are urged toward the insulating wall 3 and detached from the lug detaching apertures 11 by a tool inserted in the apertures 11 on the side of inserting a mating connector.
  • the terminal elements 2 of the contacts are allowed to be fairly larger than the contact fixing apertures 5. All that is required for the apertures 5 is that they allow the elastic fixing lugs 9 deformed toward the insulating wall 3 to pass through the apertures 5.
  • Insulating housings having contact fixing apertures substantially the same in shape and size can be used commonly to various kinds of connectors such as those having soldered or clamped lead wires. Therefore, the number of parts of connectors is reduced so as to decrease the manufacturing cost. In this manner, all the disadvantages of the prior art can be eliminated.
  • Fig. 11 illustrates a female connector mating with the male connector shown in Fig. 9.
  • This female connector comprises insulating walls on both sides and an insertion positioning flange 4 common to the insulating walls. It will not be described in further detail since the insulating walls and the insertion positioning flange of the female connector shown in Fig. 11 are substantially the same as those of the male connector shown in Fig. 9.
