Definitions

  • the invention relates to an adapter device for establishing a releasable electrical connection between contact elements of a first electrical component, e.g. of a component to be tested, and contact elements of a second electrical component, e.g. of an automatic tester.
  • Electrical components such as printed circuit boards and modules, which can contain a large number of electronic components, must be checked for errors before being installed, for example, in a data processing system.
  • devices under test generate test signals required, and checks the output of DUT output signals.
  • an electrical connection must be made between the test machine and the device under test.
  • test objects of different types have to be tested with an automatic test machine, the test object cannot be directly connected to the interface modules of the automatic test machine. Rather, an adapter device must be arranged between the connection modules of the automatic test machine and the test object. With the help of this adapter device, the lines of the interface modules are connected to the assigned lines of the test object. So if a differently designed test object is to be tested, it is only necessary to replace the adapter device or part of the adapter device, the other units of the testing machine do not have to be changed.
  • the adapter device is therefore both in electrical connection with the connection modules of the automatic test machine and with the test object and is constructed in this way; that the signal lines and potential lines of the connection modules of the automatic test machine are connected to the assigned signal lines and potential lines of the test object.
  • the object on which the invention is based is to specify an adapter device with which a releasable, correct electrical connection between a first electrical component, for example the test object, and a second electrical component, for example an automatic test machine , can be produced, which is simple and inexpensive .
  • an adapter device of the type specified in the introduction in that an exchangeable circuit board is provided which has vias in the pitch of the contact elements of the first component, the contact points in the pitch of the contact elements of the second component, and the connecting lines between the vias and the Has contact elements and that displaceable connecting parts are arranged in the plated-through holes, the displacement of which makes it possible to produce electrical contact between the contact elements of the first component and the connecting elements and electrical contact between the connecting elements and the plated-through holes.
  • a simply designed connecting part is designed as a plug-in sleeve at one end for receiving a contact element of the first component designed as a contact pin and is spread apart at the other end in the contact area for through-plating.
  • a connecting part consists of a tube which is slit and spread at the other end and of a pin which is arranged in contact with the tube and is designed as a plug-in sleeve at one end.
  • Another simply designed connecting part is designed as a plug pin at one end and spread at the other end in the contact area for through-plating.
  • a connecting part consists of a tube which is slit open and spread at the other end and a pin which is arranged in contact with the tube and is designed as a plug pin at one end.
  • the following procedure can be used to establish the electrical connection between the first component, the test object, and the second component, the automatic test machine.
  • the circuit board is moved in a first direction when the connection parts are stationary in order to make contact between the contact pads of the circuit board and the contact elements of the automatic test machine.
  • the connecting parts are pushed in the opposite direction through the plated-through holes of the printed circuit board to such an extent that contact between the connecting parts and the contact elements of the first component, the test piece, is produced and there is contact between the plated-through holes and the connecting parts.
  • This simple and inexpensive adapter device thus essentially consists of the printed circuit board, the contact elements of which can be easily adapted to the test object as well as the automatic test machine in the grid dimension.
  • This circuit board is then moved relative to the connecting parts, the test specimen and the testing machine in order to make contact.
  • Such a printed circuit board is very inexpensive and can be easily replaced.
  • the adapter device consists of a printed circuit board 1 and connecting parts 7.
  • the printed circuit board 1 contains plated-through holes 2 into which the connecting parts 7 can be inserted.
  • the plated-through holes 2 are arranged in the grid dimension of the contact elements of a test object 3.
  • the test specimen g 3 can be, for example, a printed circuit board be provided with a plug 12, the contact pins 13 of which must be connected to the connecting parts 7.
  • Contact patches 4 are also arranged on the printed circuit board 1, via which contact is made with contact pins 5 of the testing machine. These contact pads 4 are arranged on the circuit board 1 in the grid dimension of the contact elements of the automatic test machine. Electrical lines 6 are arranged between the plated-through holes 2 and the contact pads 4.
  • the electrical connection between the test specimen 3 and the printed circuit board 1 takes place with the aid of the connecting part 7.
  • These connecting parts 7 establish a plug connection from the plated-through hole 2 in the printed circuit board 1 to the plug 12 of the test specimen 3.
  • the connecting parts 7 are not firmly connected to the circuit board 1, however, they can therefore be moved in the direction of the arrow 8 relative to the circuit board 1. During this movement relative to the printed circuit board 1, contact can be made between the plug 12 of the test specimen 3 and the connecting parts 7 and also between the connecting parts 7 and the plated-through holes 2 of the printed circuit board 1.
  • FIG. 2 shows the state in which the connecting part 7 has not yet made the electrical contact between the contact pin 13 and the via 2.
  • the connecting part 7 must be pushed into the via 2, as shown in Figure 3. This creates a plug connection between the contact pin 13 of the test specimen 3 and the through-connection 2.
  • the connecting part 7 is spread out at one end.
  • the connecting part with the spread-open end is pushed into the through-contact 2 and contact is created between the connecting part 7 and the through-contact 2.
  • the electrical connection between the contact pins 13 of the device under test 3 and the contact pins 5 of the automatic test machine can be established in the following way: First, the circuit board 1 is shifted in the direction of the arrow 9 relative to the connecting parts 7 until the contact pins 5 with the contact pads 4 are open the circuit board 1 have contact. During this displacement process, no contact is made between the connecting parts 7 and the contact pins 13 of the test specimen 3 and the connecting parts 7 and the plated-through holes 2. The circuit board 1 can remain in this position as long as test objects of the same structure are tested. To establish the electrical connection between the device under test 3 and the circuit board 1, the connecting parts 7 are now moved in the direction of the arrow 8 toward the device under test 3. This creates a contact between the contact pins 13 of the test specimen 3 and the ends of the connecting parts 7 designed as plug sleeves. Furthermore, there is contact between the plated-through holes 2 and the expanded parts of the connecting parts 7.
  • the connecting parts 7 are pulled out in the opposite direction from the plated-through holes 2 of the printed circuit board 1, the contact between the connecting parts 7 and the plated-through holes 2 and solved between the connecting parts 7 and the pins of the device under test 3.
  • the more precise construction of a connecting part is shown in FIGS. 4 to 6.
  • the connecting part 7 has two components, it contains a tube 14 which is slotted and spread at one end 17.
  • a pin 15 is arranged in this tube 14.
  • This pin 15 is designed in Figure 4 and Figure 6 so that it has a receptacle 18 at one end.
  • a contact pin can be inserted into this socket 15.
  • the pin 15 protrudes so that a movement mechanism on this side can engage the pin.
  • both parts of the connecting part are stamped together in the area 16 with notches.
  • the design of the connecting part according to FIG. 5 differs from that of FIGS. 4 and 6 only in that the one side of the pin 15 is not designed as a plug sleeve, but as a plug pin 19. Accordingly, the contact element of the device under test 3 is designed as a socket 13.
