[ The PC card restraining portion 147 may be formed on the PC card seating portion 145, for example, in the shape of "? &Quot; in order to firmly restrain the PC card 20. [ The PC card restraining part 147 ensures the stable connection between the second male terminal 131 and the PC card 20 and prevents the PC card 20 from flowing in the connected state, Thereby protecting the male terminal 131.

The light emitting unit 150, the switching unit 160, the alarm unit 170, the control unit 190, and the like may be formed as separate printed circuit boards and connected to the connection unit formed on the flat plate unit 141.

The light emitting unit 150 has a plurality of light sources 151.

The switching element 160 is connected to a part of a plurality of wirings formed on the flat plate 141 (for example, a wiring connected to the power supply pin of the PC card connector 10) And a second contact 162 connected to each of the second male terminals 131 of the second connector 130. The first contact 161 is connected to the second connector 130,

The alarm unit 170 generates a buzzer sound according to the control signal of the controller 190.

The control unit 190 controls the operation of the components.

When the PC card 20 is connected to the second female terminal 131 of the second connector 130 when the PC card tester 100 of the present invention is used, the second female terminal 112 of the gender 110 Is connected to the first connector 120 and the first female type terminal 111 is connected to the PC card connector 10 so that the printed circuit board 1 recognizes the PC card 20 and the PC card 20 ) Is normally operated on the printed circuit board (1). To this end, the respective pins of the PC card connector portion 10 of the printed circuit board 1 and the respective grooves of the PC card 20 are electrically connected. For example, if the PC card connector portion 10 has 68 pins, the PC card 20 also has 68 grooves, each of which is electrically connected.

Referring to FIG. 1, these 68 pins may be composed of six power supply pins 11, 62 signals and other pins 12. Of these, six power pins 11 are longer than the other pins and are located at both ends and in the middle. Since the six power supply pins 11 are longer than other pins, the power supply pins 11 may be bent in the manufacturing process, or the pins may bend during the connection between the terminals and the terminals.

In this process, the PC card 20 is damaged and frequently replaced. In addition, it is difficult to visually confirm that the pins are bent in the connector portion 10 for a small PC card. In addition, even if a pin failure occurs, the PC card 20 may be normally operated on the printed circuit board 1, so that a failure of the pin is not detected during the inspection of the PC card 20, .

Therefore, in the PC card tester 100 of the present invention, the expensive PC card 20 is always connected to the PC card tester 100, and the gender 110 is attached to the first connector 120 to connect the PC card 20 ). In this case, the first female terminal 111 of the gender 110 may be damaged in the process of inspecting the PC card 20. However, since the gender 110 may be replaced in place of the expensive PC card 20, . The gender 110 can be replaced at a price of 50% or less as compared with the PC card 20.

In the PC card tester 100 of the present invention, in a state in which the first female terminal 111 of the gender 110 and the PC card connector 10 are connected to each other, each pin and the first female terminal 111 is detected. Detection of whether or not such a pin and the first female terminal 111 are normally connected can be made only for a part of the pin where connection failure is liable to occur.

It is possible to detect whether or not the pin and the first female terminal 111 are normally connected to the power pin having a longer length and important role than the other pins among the respective pins. These pins are shown in Fig. 1 as power pin 11, which is long and located at both ends and in the middle.

In this embodiment, each of the six light sources 151 can be connected to six power supply pins 11 through the first contact 161 of the switching element 160. [ Each switching element 160 is connected to the power supply wiring 146 of the flat plate portion 141 connected to each of the power supply pins 11.

When the power is applied while the PC card tester 100 is connected to the PC card connector 10 of the printed circuit board 1, the controller 190 firstly switches the switching element 160 to the first contact 161). When all these six pins are normally connected to the first female terminal 121, the respective light sources 151 are all emitted by the electrical connection. If there is a pin which is not normally connected among these six pins, the light source 151 connected to such a pin is not turned on.

As described above, it is possible to detect whether or not the pins of the PC card connector portion 10 and the first female type terminal 121 are normally connected, depending on whether or not each of the light sources 151 emits light. When the pins of the PC card connector portion 10 and the first female type terminals 121 are not normally connected, there are cases where the pins are bent or the first female type terminals 121 are damaged.

The control unit 190 transmits a signal to the alarm unit 170 to generate a buzzer sound when a normal connection is not detected at one or more pins of the PC card connector unit 10. [ The inspector who inspects the printed circuit board 1 may judge whether the light source 151 emits light to make an abnormal connection between the pin of the connector portion 10 for the PC card 10 and the first female terminal 121. However, It is possible to hear and judge the buzzer sound of the buzzer 170.

The light emitting unit 150, the alarm unit 170, the control unit 190, and the like may be housed in the housing 180. The housing 180 is formed to cover the flat plate 141 and the flat plate 141 and the housing 180 can be fastened by the fastening member 185. A part of each light source 151 of the light emitting unit 150 is exposed on the surface of the housing 180 so that the inspector can easily confirm whether or not the light source 151 emits light.

In order to easily identify the pin numbers of the PC card connector unit 10 connected to the respective light sources 151, pin numbers connected thereto may be displayed at the front ends of the respective light sources 151. This pin number display portion 181 indicating the pin number can be attached to the surface of the housing 180. A "FAIL indicator 182" that is separately lit from the alarm unit 170 is located adjacent to the pin number display unit 181 when a normal connection is not detected at one or more pins of the PC card connector unit 10 .

Next, when a normal connection is detected in all the pins of the PC card connector 10 connected to the first contact 161, the controller 190 secondarily connects the switching element 160 to the second contact 162, So as to check whether the PC card 20 is normally operated on the printed circuit board 1. In this case,

After detecting whether or not the pin of the connector portion 10 for the PC card and the first female terminal 111 are normally connected, it is checked whether or not the PC card 20 is normally operated on the printed circuit board 1 , This order may be reversed.

According to the PC card tester 100 of the present invention described above, instead of the expensive PC card 20, the gender 110 is directly connected to the PC card connector 10 of the printed circuit board 1, 110 and the PC card 20 are electrically connected to each other to check whether the PC card 20 is normally operated on the printed circuit board 1. [ Accordingly, it is only necessary to replace the gender 110 because the PC card 20 is not damaged while the PC card 20 is damaged in repeated connection with the pins of the PC card connector 10. Therefore, only the inexpensive gender 110 can be replaced in place of the expensive PC card 20, so that the inspection cost of the printed circuit board 1 can be reduced.

In addition, by the selective connection of the switching element 160 having the first contact 161 and the second contact 162, the pins of the connector portion 10 for the PC card and the first female terminal of the gender 110 It is possible to detect whether or not the terminal 111 is normally connected. Accordingly, it is possible to judge whether the pins of the PC card connector portion 10 are bent or the first female terminal 111 of the gender 110 is abnormal, and the inspector can take necessary measures.

After detecting whether the pins of the PC card connector 10 and the first female terminal 111 of the gender 110 are normally connected, the switching element 160 is switched so that the second contact 162 is connected It is possible to check whether or not the PC card 20 is normally operated on the printed circuit board 1. [

Therefore, by connecting the PC card tester 100 of the present invention once to the PC card connector section 10 of the printed circuit board 1, the pins of the PC card connector section 10 and the pins of the gender 110 It is possible to simultaneously check whether the female terminal 111 is properly connected and whether the PC card 20 is normally operated on the printed circuit board 1. [

Further, a pin number display unit 181 is attached to the front end of the light source 151, so that the inspector can easily grasp which of the plurality of pins has a problem.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention will be.
