Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector, and more particularly to a board mount type connector.

[0002]

2. Description of the Related Art As a board mounting type connector, for example, a connector described in Japanese Utility Model Laid-Open No. 1-113981 is known. This connector is a so-called bottom entry type connector which is attached to the edge of the board and has a fitting portion facing the board. The contact pin extends from the fitting part to the board side through the upper part of the housing of the connector.
It is shaped like a letter. Therefore, the mounting portion (the tine portion) of the row of contact pins to the substrate is arranged on one side of the housing. Therefore, when the housing is attached to the board, its fixation is not strong, and it may tilt when receiving external force.
There is a possibility that the connection between the connectors may be hindered or the solder in the tines may be cracked to reduce the reliability of the connection.

To solve this problem, there is a housing provided with a reinforcing means for mounting. For example, Japanese Utility Model Laid-Open No. 1222271 discloses such a connector, which is shown in FIG. On one side of the housing 102 of the connector 100, the tine portion 106 of the electrical contact 104 has a through hole (through hole) 1 of the substrate 108.
It is inserted through the wire 10 and fixed by the solder 112.
Further, on a wall adjacent to one side of the housing 102, a pin 114 for fixing the substrate extends toward the substrate 108 and is similarly fixed to the through hole 110 with a solder 112.
This reinforces the mounting of the housing. However, the pin 114 is required as a separate component, which causes problems such as an increase in cost and an increase in the number of assembling steps.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and solves the problems such as the low mounting strength of conventional connectors, the increase in the number of parts, the increase in cost, and the increase in the number of assembling steps. With the goal.

[0005]

SUMMARY OF THE INVENTION A connector according to the present invention is a connector attached to a board by a plurality of electrical contacts extending along one side wall of the housing that is substantially orthogonal to the board, wherein the electrical contacts at both ends of the electrical contact are electrically connected. The contact may extend along an end wall that is adjacent to the one side wall and is substantially orthogonal to the substrate.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a front view of the connector I of the present invention. FIG. 2 is a side view of the connector 1 of FIG. 1 viewed from the arrow. FIG. 3 is a bottom view of the connector 1 of FIG. 1 viewed from the arrow III. FIG. 4 is a cross-sectional view of the connector 1 of FIG. 1 taken along line IV-IV. FIG. 5 is a partial plan view showing a mounting portion of a board on which the connector of FIG. 1 is mounted.

Referring first to FIG. 1, 2 and 80,8
Reference numeral 0'indicates an insulative housing having a substantially rectangular outer shape and an electric contact (hereinafter, simply referred to as a contact). The fitting surface 6 of the housing 2 is located on the lower side in the drawing. A recess 8 for receiving a mating connector (not shown) is formed inward from the fitting surface 6, that is, in the upper part of the drawing, as shown by a broken line. A plurality of contacts 80, 80 'extend from the top wall 10 of the housing 2 and are bent toward a substrate 150 (see FIG. 5) such as a printed board to form tine portions 82, 82'. The row of contacts 80 at the center is folded to the side of the paper where
The contacts 80 ′ on both ends extend outward along the top wall 10 in a direction orthogonal to the contacts 80, and further extend along the end wall 14.

Projecting portions 16 are provided at both ends of the lower portion of the housing 2.
a and 16b are integrally formed, and contact 80 '
The tine portion 82 ′ of the through hole 18 of the protruding portions 16 a and 16 b
Retained within. In this embodiment, the contacts 80 and 80 '
Are contacts of the same shape formed from a wire having a substantially square cross-sectional shape. In the figure, 20 is an opening formed in the side wall 11. The side wall 11 further has an opening 20 and a side wall 1.
The extension of 1 forms the latch arm 22. The latch arm 22 can swing around the hinges 24, 24 formed by the opening 20. When the mating housing is inserted into the recess 8, the mating engaging part (not shown)
And the latch arm 22 are engaged with each other to lock the two housings to each other. The latch arm 22 is provided with a rib 25 for reinforcing the latch arm 22.

Next, referring to FIG. 2, a side view of the connector 1 shown in FIG. A protrusion 28 is integrally formed with the housing 2 at a lower portion of the side wall 26 of the housing 2. The tine portion 82 of the contact 80 is inserted and retained in the through hole 30 of the protruding portion 28.

Next, FIG. 3 shows the connector 1 shown in FIG.
The bottom view seen from II is shown. Reference numerals 84 and 84 'in the figure respectively indicate connection portions of the contacts 80 and 80'. Connection parts 84, 8
The reference numeral 4'projects into the concave portion 8 and contacts a counterpart contact (not shown). Protrusions 32a and 32b are formed on the side wall 11, and grooves 34a are formed inside the protrusions 32a and 32b.
34b are formed. When mating with the mating housing, a ridge (not shown) formed in the mating housing is inserted and guided along the grooves 34a and 34b. As a result, the connectors are smoothly fitted to each other.
Further, since the grooves 34a and 34b are formed only on one side, it is possible to prevent erroneous fitting.

FIG. 4 shows a sectional view of the connector 1 of FIG. 1 taken along line IV-IV. The shape of the contact 80 can be easily understood from the drawing.

FIG. 5 shows a plan view of the substrate 150 to which the connector 1 is attached. The board 150 is formed with a notch 152 and through holes 154 and 154 'around which the tines 82 and 82' are inserted and soldered, respectively. The notch 152 is formed corresponding to the opening 9 of the fitting surface 6 of the housing 2 shown by an imaginary line. The mating housing passes through the notch 152 and is inserted into the recess 8. Since the tines 82 ′, 82 ′ of the housing 2 are inserted and fixed in the through holes 154 ′, 154 ′, the housing 2 can be held extremely stably against an external force in the direction of arrow F in the figure. it can. Also housing 2
Since they are arranged on both sides of the housing 2, they have a strong resistance against the external force in the longitudinal direction of the housing 2. Thus, the connector 1 is particularly suitable for mounting on the edge of the substrate 150.

The preferred embodiment of the present invention has been described above in detail, but the present invention is not limited to this embodiment, and various modifications and changes can be considered depending on the application. For example, the contacts 80, 80 'may be made of a wire material having a circular cross section. Further, the contact 80 ′ may be formed by extending or shortening the shape of the extension 81 ′ along the top wall 10 as required. Each contact 80 is provided on the side wall 26 of the housing 2.
A protruding wall (not shown) may be provided between the contacts 80 to prevent the contacts 80 from deforming when an external force is applied thereto, and to prevent the contacts 80 from coming into contact with each other to cause a short circuit.

[0015]

The connector of the present invention extends along one side wall of the housing so that the contacts at both ends of the plurality of contacts mounted on the board are extended to the side of the end wall orthogonal to the side wall. Play. That is, since it is firmly attached to the substrate, it is possible to prevent the occurrence of twisting or solder cracks at the tines when the connectors are fitted to each other. Since the contact itself is used to reinforce the attachment of the connector, the number of parts, the number of assembling steps, the cost, etc. can be reduced.
