Definitions

  • This invention relates to a receptacle connector with a receptacle shell which is fixed to a circuit board known in the art.
  • a receptacle shell is used for magnetically shielding a connector body and is formed by press working to have a soldering post.
  • the soldering post is inserted into a through-hole which is formed in the circuit board. In this state, a soldering is carried out between the soldering post and the circuit board in the manner known in the art.
  • the soldering post has a rectangular shape in a cross-sectional shape thereof, while the through-hole has a circular shape in a cross-sectional shape thereof.
  • a receptacle connector for being mounted on a circuit board having a hole defining surface defining a through-hole
  • the receptacle connector comprising a connector body and a receptacle shell formed from a plate member and coupled to the connector body, the receptacle shell comprising a shell body for covering the connector body, and a soldering post formed extending from the receptacle shell for being soldered to the circuit board with being inserted in the through-hole, the soldering post being curved along the hole defining surface.
  • a receptacle shell for being coupled to a connector body of a receptacle connector which is mounted on a circuit board having a hole defining surface defining a through-hole
  • the receptacle shell comprising a shell body for covering the connector body, and a receptacle shell formed from a plate member and coupled to the connector body, the receptacle shell comprising a shell body for covering the connector body, and a soldering post formed extending from the receptacle shell for being soldered to the circuit board with being inserted in the through-hole, the soldering post being curved along the hole defining surface.
  • the conventional receptacle connector comprises a connector body 23 and a conductive receptacle shell 25 which is provided to cover the outer surface of the connector body 23.
  • the connector body 23 comprises a plurality of conductive contacts 27, such as pin contacts, and an insulator 28 fixedly holding the conductive contacts 27.
  • the receptacle shell 25 is formed by press-working a conductive plate member and comprises a shell body 26 and a soldering post 29 which is formed integral with the shell body 26. When the receptacle connector is mounted on a circuit board 33, the soldering post 29 is inserted into a through-hole 31 made in the circuit board 33.
  • the soldering post 29 is provided on a shell side plate 35 of the shell body 26.
  • the shell side plate 35 is disposed on an outer side of a connector body 23.
  • the soldering post 29 has a soldering portion inserted into the through-hole 31.
  • a positioning pin 41 is provided to extend parallel to the soldering post 29.
  • the positioning pin 40 is inserted into a positioning hole 43 formed in the circuit board 33.
  • the above-mentioned receptacle connector has a disadvantage as described in the preamble of the instant specification.
  • the receptacle connector comprises a connector body 53 and a conductive receptacle shell 55 coupled to cover the outer surface of the connector body 53.
  • the connector body 53 comprises a plurality of conductive contacts 56, such as pin contacts, and an insulator 60 fixedly holding the conductive contacts 56.
  • the receptacle shell 55 has a shell body 52 covering the connector body 53 and a pair of soldering posts 57 each extending from the shell body 52.
  • Each soldering post 57 is formed integral with the shell body 52 and is inserted into a through-hole of a circuit board 63 when the receptacle connector is mounted on the circuit board 63.
  • Each soldering post 57 is provided on a shell side plate 54 of the receptacle shell 55. Although only one side of the receptacle shell 55 is shown in Fig. 12, the soldering post 57 is also provided on the other side.
  • Each soldering post 57 has a peripheral surface which is similar to a hole defining surface 65 in a shape thereof and faces the hole defining surface 65 with a particular gap left between the peripheral surface and the hole defining surface 65 when each soldering post 57 is inserted in the through-hole 61.
  • each soldering post 57 is curved along the hole defining surface 65 to have a C-shape in a cross-section thereof.
  • the hole defining surface 65 is circular in a cross-section.
  • the peripheral surface 58 is semicircular in a cross-section.
  • the hole defining surface 65 extends to have a predetermined curvature.
  • the peripheral surface 58 extends to have a particular curvature greater than the predetermined curvature.
  • the peripheral surface 58 has a deformed portion or a lateral hole 59 which faces the hole defining surface 65 when each soldering post 57 is inserted in the through-hole 61.
  • each soldering post 57 are press-formed by stamping out from a conductive metallic plate material.
  • the shell body 52 is structured so as to correspond to the outer configuration of the connector body 53.
  • each soldering post 57 is press-formed to have substantially semi-cylindrical or semicircle shape.
  • each soldering post 57 has an arcuate inner periphery and outer periphery.
  • the wall thickness of each soldering post 51 is not specifically limited.
  • each soldering post 57 should be made smaller than the radius of the through-hole 61.
  • the positioning for mounting the receptacle connector is made by the soldering posts 57.
  • setting of a radius of curvature of each soldering post 57 should be decided. Namely, in the case of a radius of curvature of each soldering post 57 is too small, the distance within which the soldering post 57 moves inside the through-hole 61 becomes greater, and therefore, it is required that the dimension is decided not to lower the accuracy of the positioning. However, needless to say, this requirement is not demanded severely.
  • soldering posts 57 having such an arcuate shape and with the connector being provided with the soldering posts 57 at both sides, respectively, the accuracy of positioning is obtained without having play of soldering posts in the through-hole 61 on the circuit board 63.
  • soldering posts 57 Since the soldering posts 57 has the semicircle shape as shown on the left side of Fig. 14, the particular gap or a space between the outer periphery of the arc of the soldering post 57 and the inner periphery of the through-hole 61 is filled with a solder 71, and this allows the solder 71 to contact with wider areas, thereby to improve both solderability and strength.
  • each soldering post 57 is substantially semicircle, a contact area of the solder is made wider even with a small quantity of soldering, thereby to improve solderabilty, which in turn, improves the strength of securing the receptacle shell 55 and the connector.
  • Positioning on the circuit board 61 is carried out by using the soldering posts 57, therefore, there is no need for providing a positioning pin separately on the receptacle shell 55. Further, there is no need for providing the positioning hole in the circuit board 63 for receiving the positioning pin. Consequently, the manufacture of the receptacle shell 55 and the circuit board 63 is simplified, and in turn, lowering of the cost is made possible.
  • Fig. 15 the description will be directed to a receptacle connector according to another embodiment of this invention. Similar parts are designated by like reference numerals.
  • the hole defining surface 65 is cylindrical.
  • the outer peripheral surface 58 of each soldering post 57 is cylindrical and has an outer diameter which is smaller than that of the through-hole 61. It should be noted that a gap is left between the outer peripheral surface 58 and the hole defining surface 65 to form a ring shape.
  • each soldering post is curved along an ellipsoidal shape or a polygonal shape.
