FIGS. 1A and 1B are views showing a main part of a board-mounted connector, wherein FIG. 1A is a plan view, FIG. 1B is a front view, and FIG. 1C is a bottom view. FIG. 2 is a line AA in FIG.
FIG. FIG. 3 is a plan view illustrating a configuration of a circuit board to which the board-mounted connector is mounted.

Referring to FIG. 1, the connector body 15 has an elongated housing 20 and two rows of contacts 30 arranged therein. The housing 20 has a protruding wall 21 protruding from the base 25 toward the top side at a center position in the axial direction thereof.
Having. The projecting wall 21 extends over a length close to the entire length of the housing 20. The contact 30 has a contact portion 31 arranged along the side surface of the protruding wall 21 for contact with a contact of a mating connector (not shown). The connecting portions 32 of the contacts 30 for connecting to the two rows of pads 110 formed on the connector mounting surface 101 of the circuit board 100 (see FIG. 3) are arranged in two rows along the bottom surface 22 of the housing 20. You. As can be understood from FIG. 2, the connection part 32 of the contact 30 is connected to the pad 11 of the circuit board 100.
It is shaped so as to be elastically displaceable so as to be elastically contacted with zero. In FIG. 2, the bent shape when contacting the circuit board 100 is shown by a broken line.

As shown in FIGS. 1 and 2, an elongated metal plate 60 is provided on the top surface 21a of the protruding wall 21.
Is disposed so as to substantially cover the. Further, through holes 23 are formed at five places in the length direction of the protruding wall 21, and holes 61 are formed in the metal plate 60 so as to be aligned with the through holes 23.
As shown, a rivet 50 is inserted into the hole 61 and the through hole 23 so as to penetrate them. Rivet 50
Is engaged with the top surface 21a of the projecting wall 21 of the housing 20 via the metal plate 60. The diameter of the head 51 is a metal plate 6
0 and the width of the protruding wall 21 are set to be equal to or smaller than the width. It should also be noted that the protruding wall 21 extends to the bottom side inside the base 25 to form the inner protruding wall 24. Still referring to FIG. 3, the circuit board 100 is provided with a rivet receiving hole 120 that penetrates a predetermined position to receive the rivet 50 for mounting a board-mounted connector.

On both sides of the base 25 of the housing 20, further elongated metal plates 70 are mounted.
Reference numerals 0 and 70 are for reinforcing the housing 20. The metal plate 70 is formed to be slightly thicker than the metal plate 60. It should be noted that the metal plate 60 is arranged in a horizontal plane direction, while the metal plate 70 is arranged in a vertical plane direction.

FIG. 4 is a plan view showing a metal plate used to complete the mounting of the board-mounted connector.
FIGS. 5A and 5B are side views showing a state where the board-mounted connector has been mounted on the circuit board. FIG. 5A shows a state where the board-mounted connector is mounted on a relatively thin circuit board, and FIG. It is a figure which shows the state attached to each.

The metal plate 80 shown in FIG. 4 completes the board mounting type connector 10 in cooperation with the main part 15 shown in FIGS. 1 and 2, and completes the mounting. According to FIG. 4, the metal plate 80 is made to be elongated and also the through-hole 2 of the housing 20.
Holes 81 are formed at intervals and dimensions corresponding to No. 3.
Its length is shorter than the metal plate 60, and its edge 82 has a curved shape. Since the metal plate 80 is placed in direct contact with the circuit board as described later, the mounting area required for the circuit board can be minimized by shortening the length of the metal plate 80.

The metal plate 80 is mounted on the circuit board 1 as shown in FIG.
00 is arranged along a surface 102 opposite to the connector mounting surface 101. The rivet 50 projecting from the main part 15 of the board-mounted connector 10 is placed so as to pass through the rivet receiving hole 120 of the circuit board 100 when the main part 15 is provisionally placed. Hole 8
1 (see FIG. 4). Thereafter, the tip of the rivet 50 is pressed and deformed so as to be crushed. (A schematic shape before being deformed is shown by a virtual line in FIG. 5.) As a result, the housing 20 and the circuit board 100 are
The housing 20 is clamped and fixed between the circuit boards 80 so as to be pressed toward the circuit board, and the connection portions 32 of the contacts 30 are elastically contacted with the pads 110 of the circuit board 100 to realize stable electric connection. As can be understood from FIG. 5, the rivet 50 can be selected according to the thickness of the circuit board 100. That is, a relatively short rivet 50a is selected when the rivet is mounted on a relatively thin circuit board 100a as shown in FIG. 5A, and a relatively long rivet is mounted when the rivet is mounted on a relatively thick circuit board 100b as shown in FIG. 5B. 50b is selected.

An advantage of the board-mounted connector 10 is that it is firmly fixed to the circuit board 100 with a minimum length and is sufficiently reinforced. That is, according to this configuration, even when the housing 20 or the circuit board 100 slightly warps, the housing 20 can be reliably pressed against the circuit board 100 over the length direction. Further, the reinforcement of the connector is made firmly by the metal plates 60, 80, or the metal plate 70 in addition thereto. Such a configuration is particularly effective in a configuration in which the contact 30 accommodated in the housing 20 elastically contacts the pad 110 of the circuit board 100 as described above.

As described above, the board mounting type connector according to the preferred embodiment of the present invention has been described. However, this is merely an example, and does not limit the present invention. Changes are possible. For example,
The rivet 50 may be replaced with a ground member, the shape of the inner protruding wall 24 may not be a simple shape as shown, and the rivet 50 positions the housing 20 on the circuit board 100. You may make it receive in the through-hole 23 later.

[0025]

According to the board-mounted connector of the present invention, a plurality of through holes for receiving the fastening means are formed at a plurality of predetermined positions in the longitudinal direction of the protruding wall. The housing is firmly fixed to the board, and the housing is firmly pressed toward the circuit board in the length direction. Further, since the stress applied at the time of attachment is distributed over the entire length of the housing, there is no possibility that the housing is damaged.

Further, the board-mounted connector according to the present invention is characterized in that a through-hole is formed at a plurality of predetermined positions along the entire length of the housing, and an elongated first metal plate arranged along the top surface of the housing; An elongated second metal plate disposed on a surface opposite to the mounting surface of the board-mounted connector, wherein the fastening means is received in the through-hole and the first metal plate and the second metal plate are provided. The housing is configured to be engaged with both of the plates, whereby the housing is sandwiched and fixed between the first metal plate and the second metal plate together with the circuit board, so that the housing is sufficiently reinforced and has a lengthwise direction.
