Definitions

  • the present invention relates to a connector mainly used for a printed circuit board and, more particularly, to a low-profile connector.
  • a typical conventional connector has a structure as shown in Figures 8 and 9. That is, a receptacle contact is arranged in a housing to receive a pin to be connected.
  • the connector having such a structure is miniaturised, the stroke of the contact is shortened, and deformation of a spring of the contact is reduced. As a result, an inserted pin cannot be satisfactorily held. Thus, miniaturisation of the conventional contact is limited.
  • a connector comprising a housing having a cavity for storing a conductive portion to be connected, and a contact having a body portion extending outside said cavity and a bent distal end portion deformably extending through an opening of said cavity from outside said cavity, wherein when said portion to be connected is inserted in said cavity, said distal end portion of said contact is brought into contact with said portion to be connected, thus achieving an electrical connection, the body portion engaging a groove formed in said housing, a portion of said groove being obliquely formed outside a bottom portion of a side wall defining the cavity and the body portion of the contact having an inclined portion corresponding to said oblique portion of said groove whereby the body portion and the bent distal end portion can be preformed and then located in said housing by insertion obliquely from above the housing.
  • a connector comprising a housing having a cavity for storing a conductive portion to be connected, and a contact having a body portion extending outside said cavity and a bent distal end portion extending through an opening of said cavity from outside the cavity, wherein when said portion to be connected is inserted into said cavity, said distal end portion of said contact is brought into contact with said portion to be connected, thus achieving electrical connection, consequent deflection of the distal end portion being achieved at least in part by bending of the contact outside and away from the cavity.
  • Figures 1 to 5 show a first embodiment of the present invention.
  • reference numeral 20 denotes contacts constituted by deformably bent distal end portions 21, connecting portions 23, and body portions 22 connecting them.
  • Reference numeral 10 denotes a housing in which a plurality of cavities 11 for receiving pins of members 100 to be connected are arrayed.
  • Fig. 2 shows a state wherein the contacts are mounted on the housing. As shown in Fig. 2, the distal end portion 21 of each contact extends in an opening 12 of the corresponding cavity of the housing, so that the body portion 22 is fixed outside the cavity 11, and the connecting portion 23 extends outwardly from the housing.
  • each contact is inserted in a hole formed in a printed circuit board or is in contact with a pad provided thereon, and is fixed thereto by soldering.
  • Fig. 3 is a longitudinal sectional view of Fig. 2, and shows procedures for mounting the contact on the housing.
  • a groove 32 is formed on the outer surface of the housing so as to receive the contact from obliquely above as indicated by an arrow in Fig. 3 and to engage with and hold it.
  • a broken line in Fig. 3 indicates a state during insertion of the contact in the groove 32.
  • a portion of the groove 32 of the housing is obliquely formed outside a bottom portion of a side wall defining the cavity.
  • the body portion 22 of the contact has an inclined portion 22a engaged with the inclined portion of the groove.
  • Fig. 4 is a sectional view taken along a line A - A in Fig. 3. As can be seen from Fig. 4, a narrowed portion 23a is formed in the connecting portion contiguous with the body portion 22 of the contact.
  • Fig. 5 is a side view of Fig. 3.
  • reference numeral 32a denotes a gap provided outside the groove 32 of the housing to communicate therewith.
  • the gap 32a is formed to be slightly wider than the narrowed portion 23a of the contact.
  • reference numeral 22b denotes a projection 22b projecting from the body portion 22 of the contact.
  • the projection 22b abuts against the gap 32a, thus fixing the contact to the housing.
  • the shape of the contact will be explained below.
  • the shape of the contact before it is inserted in the housing is as follows. That is, the body portion 22 and the connecting portion 23 are linearly and integrally formed, as indicated by a broken line.
  • the connecting portion 23 is bent clockwise, as indicated by the arrow in Fig. 3, so as to extend vertically. Since the narrowed portion 23a has a smaller width than that of the gap 32a even in the contact with the bent connecting portion 23, when the contact is inserted in the groove 32 of the housing, the narrowed portion 23a can pass through the gap. Thus, the contact can be easily mounted on the housing.
  • the pin When a pin of the portion 100 to be connected is inserted in the housing with the contact, the pin is brought into contact with the bent distal end portion 21 of the contact in the opening 12 of the cavity. Along with insertion of the pin, the distal end portion 21 of the contact is extended, and holds the pin stored in the cavity 11 by its elastic force.
  • Figs. 6 and 7 show a second embodiment of a connector according to the present invention.
  • This embodiment can be realized such that after a contact indicated by a broken line in Fig. 3 is mounted on the housing, the contact is bent counterclockwise.
  • the width of the housing corresponds to a height of the connector in use (see Fig. 6). Therefore, in this embodiment, a connector having a lower profile than that in the first embodiment can be realized.
  • the insertion direction of a pin is parallel to a printed circuit board to be mounted.
  • the structure of the connector according to the present invention has been described. With this structure, the present invention can provide the following effects.
  • the contact When the contact is mounted on the housing, it can only be engaged with the groove of the housing obliquely from above the housing, resulting in very easy assembly of the connector.
  • this contact can be an anti-overstress contact.
  • the contact body Since the contact is fixed outside the cavity, the contact body need not be inserted in the cavity, and the cavity does not have an open bottom (in a conventional type, the bottom of the cavity is commonly used as an insertion hole of the contact, as shown in Fig. 8). Therefore, the problem of the open bottom of the cavity, e.g., entrance of flux of solder can be prevented.
