Abstract

PROBLEM TO BE SOLVED: To prevent a solder between a conductor pattern of a board and a contact of a connector mounted on a surface of the board from being damaged and prevent the conductor pattern from peeling off when an external force is applied to the connector.SOLUTION: A connector 1 includes a contact 2, a housing 3 that holds the contact 2, and a holddown 4 that fixes the housing 3 to a printed board on which the housing 3 is disposed. The contact 2 includes a connecting part 21 that is surface-mounted on the printed board. Since an insertion part 41 of the holddown 4 is inserted into a hole formed on the printed board and soldered, the fixing strength of the holddown 4 to the printed board is increased. Even when external force acts on the connector 1, the insertion part 41 of the holddown 4 can withstand a large load, such that the load applied to the solder between the conductor pattern of the printed board and the connection part 21 of the contact 2 is reliably reduced.SELECTED DRAWING: Figure 1

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 to 3, the connector 1 according to the first embodiment of the present invention includes a contact 2, a housing 3 that holds the contact 2, and a holddown that fixes the housing 3 to a printed circuit board (board) 5. 4.

  The contact 2 is connected to the connection part 21 that is surface-mounted on the printed circuit board 5, is connected to the connection part 21, is connected to the holding part 22 that is held in the housing 3, and is connected to the holding part 22, And a contact portion 23 in contact therewith. The contact 2 is formed by punching a metal plate. The contact part 23 and the holding part 22 extend along the plate thickness direction BD of the printed circuit board 5. A press-fitting protrusion 221 is formed on the back surface of the holding part 22. The connecting portion 21 is along the connector longitudinal direction (orthogonal direction) BFD orthogonal to the plate thickness direction BD and the arrangement direction AD of the contacts 2 so that it can be soldered to the conductive pattern 53 formed on the surface 5A of the printed circuit board 5. Extend. Here, the term “orthogonal” does not mean only the strict sense of orthogonality, but also includes that which intersects the plate thickness direction BD and the arrangement direction AD substantially at right angles.

  As shown in FIG. 6, the hold-down 4 is held by the housing 3, the two insertion portions 41 inserted into the holes 51 formed in the printed circuit board 5, the connecting portion 42 that connects the two insertion portions 41. Holding part (hold-down side holding part) 43. An imaginary line (two-dot chain line) written in the holddown 4 in FIG. 2 indicates a boundary between the insertion portion 41, the coupling portion 42, and the holding portion 43. The hold down 4 is formed by punching a metal plate. The connecting portion 42 extends linearly along the connector front-rear direction BFD, and the holding portion 43 is connected to both ends of the connecting portion 42. The holding portion 43 is formed with a press-fitting projection 431.

  Each of the two insertion portions 41 extends vertically from the connection portion 42. The two insertion parts 41 are parallel. The insertion portion 41 is designed to have such a length that the distal end portion of the insertion portion 41 protrudes from the hole 51 when the insertion portion 41 is inserted into the hole 51 of the printed circuit board 5 (see FIGS. 4 and 6). The insertion portion 41 is soldered to the printed circuit board 5 by a method of immersing the back surface 5B of the printed circuit board 5 in a solder bath (not shown).

  The housing 3 includes a housing main body portion 31 that holds the plurality of contacts 2 and a pair of housing side portions 32 provided on both sides of the housing main body portion 31. The housing 3 is formed of an insulating material (for example, synthetic resin). The housing side portion 32 extends along the connector front-rear direction BFD.

  The housing main body 31 has a substantially quadrangular prism shape. On the front surface 31 </ b> A side of the housing main body 31, a plurality of contact accommodating portions 311 that accommodate the contacts 2 are formed at equal intervals in the arrangement direction AD. The upper and lower portions of the contact accommodating portion 311 communicate with the outside of the housing main body 31 (see FIG. 5). When the contact 2 is pushed into the contact housing portion 311 with a certain pressure from the bottom surface 31C side of the housing main body portion 31, the protrusion 221 of the holding portion 22 of the contact 2 bites into the inner surface of the contact housing portion 311 of the housing main body portion 31, The contact 2 is held by the housing body 31. The contact part 23 of the contact 2 is accommodated in the upper part of the contact accommodating part 311, and the connection part 21 of the contact 2 protrudes from the lower part of the contact accommodating part 311 to the outside.

  On the bottom surface 31C of the housing main body 31, a protrusion 312 is formed to make the gap between the bottom 31C of the housing main body 31 and the surface 5A of the printed circuit board 5 constant (see FIG. 5). The length of the protruding portion 312 in the plate thickness direction BD is substantially equal to the length in the plate thickness direction BD of a part of the connecting portion 21 protruding from the bottom surface 31C of the housing main body 31. The protrusion 312 is located on the rear side of the connection portion 21 of the contact 2 in the connector front-rear direction BFD. When the housing 3 is disposed on the surface 5 </ b> A of the printed circuit board 5, the protrusion 312 hits the surface 5 </ b> A of the printed circuit board 5. The length L1 between the two insertion portions 41 of the hold-down 4 in the connector front-rear direction BFD is longer than the length L2 of the housing body 31 in the connector front-rear direction BFD (see FIG. 6). In this embodiment, the length L1 between the two insertion portions 41 is the length from the front surface 41A of the front insertion portion 41 to the back surface 41B of the rear insertion portion 41 in the connector front-rear direction BFD.

  The housing side part 32 has a hole 321 for receiving the holddown 4. The hole 321 extends along the connector front-rear direction BFD. The hole 321 is a hole penetrating from the upper surface 32A to the bottom surface 32B of the housing side portion 32 (see FIG. 6). The hole 321 includes one press-fit space portion 321A into which the holding portion 43 is press-fitted, and two insertion space portions 321B into which the insert portion 41 is inserted. The insertion space portion 321B communicates with the press-fit space portion 321A. A part of the insertion portion 41 protrudes downward from the bottom surface 32B of the housing side portion 32 through the insertion space portion 321B.

  There is no step between the bottom surface 32B of the housing side portion 32 and the bottom surface 31C of the housing main body portion 31 (see FIG. 5). There is a part of the housing side portion 32 between the connecting portion 42 of the hold down 4 and the printed circuit board 5 (see FIG. 6). The tip 21A of the connection portion 21 of the contact 2 is located closer to the housing main body 31 than the front surface 41A of the front insertion portion 41 in the connector front-rear direction BFD (see FIG. 5).

  A cylindrical projection 322 for positioning is formed on the bottom surface 32B of one housing side portion 32 (see FIG. 6), and a cylindrical projection 323 for positioning is formed on the bottom surface 32B of the other housing side portion 32. It is formed (see FIG. 5). The protrusions 322 and 323 are respectively positioned between the two insertion portions 41 of the hold down 4 (see FIGS. 5 and 6). The projecting portions 322 and 323 have different sizes (in this embodiment, the outer diameters of the projecting portions 322 and 323), and the outer diameter of the projecting portion 322 is larger than the outer diameter of the projecting portion 323. The holes 52A and 52B formed in the printed circuit board 5 correspond to the sizes of the protrusions 322 and 323 (see FIG. 4). Since the protrusions 322 and 323 have different sizes, if the connector 1 is mistakenly placed on the printed circuit board 5 with the front and back surfaces of the connector 1 reversed, the protrusion 322 is placed in the hole 52B of the printed circuit board 5. Since the connector 1 is tilted without entering, the operator notices that the orientation of the connector 1 is not correct.

  When the connector 1 is fitted to the mating connector, the contact portion 23 of the contact 2 of the connector 1 contacts the mating contact of the mating connector, and the contact 2 and the mating contact are electrically connected.

  The connector 1 is soldered to the printed circuit board 5, the mating connector is soldered to another printed circuit board (mating board) (not shown), and the fitting direction of the connector 1 to the mating connector (the fitting direction of the housing) ) FD coincides with the thickness direction BD of the printed circuit board 5. Therefore, when the connector 1 is fitted to the mating connector, the operator cannot see the connector 1 and the mating connector, so the mating connector and the connector are moved while moving the connector 1 in the direction perpendicular to the plate thickness direction BD. Must be aligned with 1.

  At this time, the connector 1 collides with the mating connector, and a force in a direction orthogonal to the plate thickness direction BD acts on the connector 1. Since the hold down 4 is fixed to the printed circuit board 5, the load is not concentrated on the solder between the conductor pattern 53 of the printed circuit board 5 and the connection portion 21 of the contact 2. Further, the insertion portion 41 of the hold down 4 is inserted into the hole 51 of the printed circuit board 5 and soldered to the printed circuit board 5, and the fixing strength of the hold down 4 with respect to the printed circuit board 5 is high. 41 can withstand a large load. Therefore, the load applied to the solder between the conductor pattern 53 of the printed circuit board 5 and the connection portion 21 of the contact 2 can be reliably reduced.

  The first embodiment has the following effects.

  When the insertion portion 41 of the hold down 4 is inserted into the hole 51 of the printed circuit board 5 and soldered to the printed circuit board 5, the fixing strength of the hold down 4 with respect to the printed circuit board 5 is increased, so the connector 1 is fitted to the mating connector. When an external force is applied to the connector 1 mounted on the surface of the printed circuit board 5, the solder between the conductor pattern 53 of the printed circuit board 5 and the connection portion 21 of the contact 2 of the connector 1 is not easily damaged. Since the pattern 53 is difficult to peel off, the reliability of electrical connection can be improved.

  Since the connection portion 21 of the contact 2 can be surface-mounted on the printed circuit board 5, it is not necessary to form a contact insertion hole (not shown) in the printed circuit board 5, and the degree of freedom in designing the printed circuit board is increased. .

  Since the tip end portion of the insertion portion 41 of the hold down 4 protrudes from the hole 51 of the printed circuit board 5 and is soldered to the printed circuit board 5, the fixing strength of the hold down 4 with respect to the printed circuit board 5 is further increased, and the printed circuit board 5 The load applied to the solder between the conductor pattern 53 and the connection part 21 of the contact 2 can be reduced more reliably.

  Since the hold-down 4 is held by the pair of housing side portions 32 provided on both sides of the housing main body portion 31, the fixing strength of the housing main body portion 31 with respect to the printed circuit board 5 is increased.

  The length L1 between the two insertion portions 41 of the holddown 4 is longer than the length L2 of the housing main body 31 in the connector front-rear direction BFD, and the tip 21A of the connection portion 21 of the contact 2 is the front side in the connector front-rear direction BFD. Because the external force in the connector front-rear direction BFD acts on the connector 1 that is surface-mounted on the printed circuit board 5, the external force is applied to the contact 2. Before the connection part 21 receives, the insertion part 41 on the front side of the hold down 4 receives it. As a result, the load applied to the solder between the conductor pattern 53 of the printed circuit board 5 and the connection portion 21 of the contact 2 can be reduced more reliably.

  Since there is a part of the housing side portion 32 between the connecting portion 42 of the hold down 4 and the printed circuit board 5, when an external force in the fitting direction FD acts on the housing 3, the external force is used as the connecting portion of the hold down 4. 42 is received, and the housing 3 is difficult to be detached from the printed circuit board 5. Furthermore, since the holding strength of the holddown 4 with respect to the printed circuit board 5 is high, it is added to the solder between the conductor pattern 53 of the printed circuit board 5 and the connection portion 21 of the contact 2 as compared with the case where the holddown is surface-mounted on the printed circuit board. The load (tensile load in the plate thickness direction BD) is reduced, and the housing 3 is less likely to be detached from the printed board 5.

Since the hold-downs 4 and 104 are flat, the size of the insertion portions 41 and 141 indicates the length of the insertion portions 41 and 141 in the connector front-rear direction BFD. In this embodiment, as the rear insertion portion 141 is enlarged, one insertion space portion 321B of the two insertion space portions 321B of the hole 321 is enlarged and the two holes 51 of the printed circuit board 5 are increased. One of the holes 51 is enlarged.
