Therefore, the lower contact #112_ is replaced every time, It is necessary to replace the test probes 11 fixed on the substrate stack in a whole group, which causes inconvenience in operation and high cost. [New content] Therefore, the object of the present invention is to provide a test probe that avoids excessive damage and improves the efficiency of probe replacement. Thus, the novel test apparatus comprises a substrate unit and a test unit. The substrate unit includes a lower plate, a baffle disposed on the lower plate, and a top plate disposed on the baffle, wherein the upper plate is formed with an upper passage formed to communicate with the upper passage The through hole is formed with a lower passage communicating with the through hole. The test unit includes a lower probe disposed in the channel below the lower plate, an upper probe disposed in the upper passage of the upper plate, a first buffer member disposed in the upper channel, and a set a second buffer member in the lower channel.

The two ends of the second buffering member respectively abut the upper edge of the surrounding wall of the baffle and the lower probe, and constantly provide an elastic restoring force to the lower probe. The utility model has the advantages that when the upper and lower probes are pressed against the first and second buffering members respectively, the first and second buffering members provide different elastic restoring forces to reduce contact damage, and When the first and second buffer members abut against the baffle, when the upper and lower probes are actuated by force, the two do not affect each other and increase the pressure of the contacts of each other. [Embodiment] The foregoing and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals. Referring to Figure 2, a first preferred embodiment of the novel test apparatus 2 includes a substrate unit 3 and a test unit 4. 7 M345236 The base unit 3 includes a lower plate 3 1 , a set of baffles 32 disposed on the lower plate 3 j , and a plurality of upper plates 33 disposed on the baffle 32 , wherein the upper plate 33 is formed with a baffle plate 33 . In the upper channel 330, the baffle 32 is formed with a through hole 320 communicating with the upper passage 330. The lower plate 31 is formed with a lower passage 31〇 communicating with the through hole 320. The test unit 4 includes a lower probe 41 disposed in the channel 31 之下 below the lower plate 31 and contacting the lower test contact 51, and a lower probe 41 disposed on the upper plate 33 and adjacent to the upper plate 33. An upper probe 42 that is touched by the test contact 52, a first buffer member 43 disposed in the upper channel 33, and a second buffer member 44 disposed in the lower channel 310. The lower probe 41 has a base wall 411 against the lower plate 31, a surrounding wall 412 extending upward from the periphery of the base wall 411, and extending downward from the center of the base wall 4ΐ and protruding therefrom A lower contact member 413 outside the lower plate 31 defines an insertion space 41〇 with the surrounding wall 412. The upper probe 42 has abutting member 421 against the upper platen 33, and a through hole 32 extending downward from the abutting member 421 and extending through the playing plate 32 and extending into the lower probe 41. The insertion member 425 of the insertion space 410. The first buffering member 43 (ie, a spring) is disposed on the two ends of the first probe member 43 of the upper probe 42 and abuts against the abutting member 421 of the upper probe 42 and the substrate unit 3 respectively. The baffle 32, and the first buffer member 43 constantly provides an elastic restoring force to the upper probe 42. The second buffering member 44 (that is, a spring) respectively abuts against the upper edge of the surrounding wall 412 of the substrate unit 32 and the lower probe 41, and the second buffering member 44 is opposite to the lower probe. 4 Divination provides an elastic restoring force. 8 M345236 42:==Λ,# When the upper test He 52 is close to the sin 4 421 that touches the upper probe, the abutment portion 421 is pushed against the top and pushes the first mitigation ^ 1 ^ ΜΤ The piece 43 is at this time, the first cushioning member is disposed on the baffle 32, and the other is crushed from the sinus to the sinus portion 421, thereby elastically deforming k for an upward direction.

At this time, the second cushioning member 44 has one end abutting against the playing board μ' and the other end receiving the surrounding buffer. The top edge of the 412 is so squeezing that the elastic deformation provides the downward resilient returning force of the lower probe 41 to slow the contact between the lower probe 41 and the lower test contact 51, in particular, The elastic restoring force provided by the first __, f buffering members 43 and 44 is different, and the force that can be touched with the m and the lower test joints 52, 51 can be adjusted, for example, the first and second buffering members 43 and 44 are When the elastic restoring force is 3 gram and 1 gram, respectively, the different buffering forces of the upper and lower probes 42, 41 are provided, and the 30 gram force of the upper probe 42 cannot be directly transmitted to the lower probe 41. Therefore, the lower probe 41 can reduce the damage caused to the lower contact point 51. Since the first and second buffering members 43, 44 are both against the baffle 32, when the elastic restoring force is generated by the pressing of the upper and lower probes 42, 41, the cushioning member 43 absorbs The force is not transmitted to the lower probe 41, and the force absorbed by the second cushioning member 44 is not transmitted to the upper wooden needle 42. Therefore, by this design, not only the upper and lower sides can be slowed down. The contact force between the probes 42, 41 and the upper and lower test contacts 52, 51, and the forces between the two 9 M345236 do not affect each other and increase the contact pressure of each other.
