As shown in the drawings, the connector (10) for a board according to the embodiment of the present invention forms an outer appearance of the housing (12). The housing 12 is made of an insulating material, and the terminal seating space 14 is formed by passing through the inside of the housing 12. Inside the terminal seating space 14, a terminal 20 to be described below is installed. The terminal seating space 14 is formed so as to be open to the front end and the rear end of the housing 12.

A spacer hole (16) is formed through the housing (12) so as to be formed perpendicular to the forming direction of the terminal seating space (14). A spacer 18 is provided in the spacer hole 16. The spacers 18 serve to support the terminals 20 to prevent the terminal 20, which will be described below, from being pushed backward. Of course, the spacers 18 and the spacer holes 16 are not necessarily required. That is, if the terminal 20 can be firmly supported by only a lance (not shown) formed in the terminal seating space 14, the spacer 18 may be omitted.

The terminal 20 is made of a conductive material and electrically connects between the contact 52 of the substrate 50 and the wire 24 to be signed below, which will be described below. The terminal 20 is located in the terminal seating space 14. The terminal 20 is supported by the lance and / or the spacer 18 so as not to be pushed rearward of the terminal seating space 14. The tip of the terminal 20 protrudes from the terminal seating space 14 and is at the tip of the housing 12.

An elastic piece (22) is formed at the tip of the terminal (20). The resilient piece 22 has a structure capable of being subjected to a predetermined elastic deformation. In this embodiment, the longitudinal section is made substantially U-shaped. The elastic piece 22 is formed to be substantially orthogonal to the extending direction of the terminal 20 and is elastically deformed and electrically connected by being in contact with the contact 52. The resilient piece 22 at the tip of the terminal 20 protrudes from the tip end of the housing 12.

A wire 24 is connected to the rear end of the terminal 20. The wire 24 extends to the rear of the housing 12. In the present embodiment, only one wire 24 and the terminal 20 are shown for the sake of convenience. Thus, in practice, the terminal 20 can be installed in all of the terminal seating spaces 14. [

A fastener mounting portion 26 is formed on the outer surface of the housing 12. The fastener mounting portion 26 is formed in a groove shape on the outer surface of the housing 12. The fixture mounting portion 26 is formed on an outer surface of the housing 12 over a back surface and both side surfaces except an outer surface facing the substrate 50, which will be described below. The fastener mounting portion 26 has a predetermined width and is formed lower than the adjacent outer surface of the housing 12. The fastener mounting portion 26 is formed on all three adjacent outer surfaces in this embodiment.

A guide channel 28 is formed on the bottom of the outer surface of the fixture mounting part 26 facing away from each other. The guide channel 28 serves to prevent the mounting fixture 30, which will be described below, from coming out of the housing 12 and guide the moving path. The guide channel (28) is formed lower at the bottom of the fixture mounting part (26).

The mounting fixture 30 is mounted on the fixture mounting portion 26 so that the housing 12 is mounted on the connector mounting portion 56 of the case 54 to be described below. The mounting fixture 30 is located at a position corresponding to the fixture mounting portion 26 formed on the back side of the housing 12 in which the wire 24 extends from the outer surface of the housing 12 . At both ends of the connecting body 32, there is a guide finger 34. The guide finger 34 is located in the fixture mounting portion 26 where the guide channel 28 is formed.

The guide finger 34 is formed in a substantially plate shape, and a hook 36 is formed at the tip end thereof. The latching jaw 36 is a portion that is hooked to the latching groove 58 formed in the connector mounting portion 56 of the case 54 to be described below. An inclined surface 36 'is formed at the tip of the engaging jaw 36. The inclined surface 36 'serves to facilitate insertion of the latching jaw 36 into the connector mounting portion 56.

A hooking jaw 37 is formed on the inner surface of the guide finger 34. The hooking jaws 37 are located in the guide channel 28 and serve to prevent the mounting fixture 30 from being separated from the housing 12. In addition, the hooking jaws 37 guide the movement of the mounting fixture 30 while being guided along the guide channel 28.

A seating guide 38 is formed on the side of the outer surface of the connecting body 32 on which the guide finger 34 protrudes. The seat guide 38 serves to guide one end of the elastic member 40, which will be described below. Although only one of the seating guides 38 is formed in the illustrated embodiment, a plurality of the seating guides 38 may be formed.

An elastic member 40 is provided between the mounting fixture 30 and the fixture mounting portion 26 of the housing 12. The elastic member 40 exerts an elastic force such that the connecting body 32 of the mounting fixture 30 tends to move in a direction away from the fixture mounting portion 26. [ However, the mounting fixture 30 is not separated from the housing 12 by hanging the hooking jaws 37 at one end of the guide channel 28. [

The mounting fixture 30 is hooked on the engaging groove 58 of the connector mounting portion 56 of the case 54 to be described below so that the connector 10 is not pulled out of the connector mounting portion 56 And at the same time, the resilient piece 22 at the distal end of the terminal 20 is brought into close contact with the contact 52 of the substrate 50. Of course, when the mounting fixture 30 is hooked on the connector mounting portion 56, the elastic member 40 pushes the housing 12 toward the substrate 50 so that the terminal 20 contacts the substrate 50 So as to be brought into close contact with the contact 52.

On the other hand, various elements are mounted on the substrate 50 and a circuit pattern (not shown) is provided. The circuit pattern is formed inside the substrate 50 to connect the elements to constitute a circuit. A contact point 52 is formed at the end of the circuit pattern so as to be electrically connected to the outside. In the present invention, the terminal 20 of the connector 10 is brought into contact with the contact 52 to make an electrical connection.

The substrate (50) is enclosed by a case (54). That is, the substrate 50 is installed inside the case 54. A connector mounting portion 56 on which the connector 10 is mounted is formed at a position corresponding to the contact 52. A seating space 60 is formed in the connector mounting portion 56. The seating space 60 communicates the space where the substrate 50 is positioned and the outside of the case 54 with each other. The connector mounting portion 56 is partitioned by a partition wall 57 protruding from one surface of the case 54 and the seating space 60 is formed therein. The partition wall 57 protrudes from the outer surface of the case 54 and protrudes to the inside of the case 54 to some extent. That is, a stone partition wall 57 protrudes toward the substrate 50.

An engaging groove 58 is formed on the inner surface of the partition wall 57. The latching groove 58 is a portion where the latching jaw 36 of the mounting fixture 30 is hooked. 5, the latching groove 58 is formed in a groove shape on the inner surface of the partition wall 57, but is not necessarily required to be formed with a partition wall 57 protruding toward the substrate 50, May be formed by removing a part of the liquid.

Hereinafter, a substrate connector according to the present invention having the above-described structure, a substrate using the same, and a connector connecting device will be described in detail.

In the present invention, when the substrate 50 is electrically connected to the outside, the substrate 50 has only a contact 52 without a connector, and the terminal 20 of the connector 10 contacts the contact 52, . That is, the connector 10 having the terminal 20 is positioned on the surface of the substrate 50, and the elastic piece 22 at the tip of the terminal 20 is brought into contact with the contact 52 to make an electrical connection.

To this end, a mounting fixture 30 is supported on the housing 12 of the connector 10 by an elastic member 38. The elastic member 38 pushes the housing 12 toward the substrate 50 in a state where the mounting fixture 30 is hooked on the connector mounting portion 56 of the case 554, So that the electrical connection is maintained.

Mounting of the connector 10 to the connector mounting portion 56 will be described. To this end, the connector 10 is positioned at the entrance of the seating space 60 of the connector mounting portion 56, as shown in Fig. In this state, the housing 12 is inserted into the seating space 60. When the operator presses the mounting fixture 30 in the process of inserting the housing 12 into the mounting space 60, the locking protrusion 36 formed on the guide finger 34 of the mounting fixture 30 is pressed So that the wall 57 is elastically deformed. This is accomplished by guiding the inclined surface 36 'of the latching jaw 36 to the partition wall 57.

When the latching jaw 36 of the guide finger 34 is hooked on the latching groove 58 of the partition wall 57, the mounting fixture 30 is fixed to the connector mounting portion 56, The elastic member 40 having one end supported by the seating guide 38 of the mounting fixture 30 is supported by the fixture mounting portion 26 of the housing 12 so that the housing 12 is moved toward the substrate 50 I will push. The resilient piece 40 urges the housing 12 in the direction of the substrate 50 so that the resilient pieces of the terminal 20 in the terminal seating space 14 of the housing 12 22 are in close contact with the contact 52 and are electrically connected.
