DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a probe assembly for a probe associated with a probe for detection. Defective blade 疋 'easy to disassemble 5 【Previous technology】 According to the conventional probe set, usually a fixed box or clip and the middle and probe are set in the energy / Gans Gan group The needle is locked inside. When one of the probes fails or is damaged, the needle and the needle are repaired, and it is often necessary to go to the fault of the fault but it is a waste, and the needle set has a complete set of replacement. China's announcement No. 1271, 379 patent, that is, the group 'such probe module is the combination of the whole set of locking. Needle pull in order to solve the above problems, the inventor of this case specifically proposed _ 15 disassembly and more female needle Structure, can be more expected and reduce costs and other functions. Bezia has a guarantee [invention content] & rented t Θ The main purpose is to provide a kind of probe assembly, which can be easily removed, can also be easily replaced The purpose of the needle is to provide a probe assembly which can be more (4)' and has a thin ring and lowers the efficacy of the county. In order to achieve the aforementioned purpose, according to the present invention: 2 and 2 have: - pedestal, with a - step at the front, and a hard number perforation at the step β, the peripheral wall of each of the perforations extends inwardly - 20 200907354 small diameter portion; complex probe Opening the perforations, and the probe faces are inserted into the top edge And the bottom end of the probe protrudes from the bottom surface of the base. =,,, the upper peripheral wall of the valley guide hole extends inwardly to form a small diameter portion - the guide block is placed at the step And the guiding holes: the upper part of the probe, and the bottom edge of the small diameter portion of each guiding block is clamped to the shoulder surface of the top section of the probe, the top of the probes A protruding portion protrudes from a top surface of the guiding block, the guiding block is fixed to the step by at least a fixing bolt, and a cover plate is disposed on the base and covers the probe. Therefore, the present invention has the functions of facilitating the replacement of the probes, such as easy maintenance and cost saving. [Comprehensive Mode] In order to clarify the structure and characteristics of the present invention, one of the following preferred embodiments will be described with reference to the drawings. After that, as shown in the first figure, a probe assembly 10' provided by a preferred embodiment of the present invention mainly comprises a base 11, a plurality of probes 21, a guiding block 31 and a cover plate. 41, wherein: the base 11 has a fixing portion 12 for fixing to other matching devices, and the base 11 has the fixing portion 2 extending forwardly from the extension portion 14 , the extension portion 14 has a width smaller than the fixing portion 12 , and the base portion 11 is substantially T-shaped, and the extension portion 14 forms a first-order portion 15 . The step portion 15 is provided with a plurality of perforations 16 , and a peripheral wall of the bottom portion of each of the through holes 16 extends inwardly to form a small diameter portion Π. The top surface of the step portion 15 is recessed to form a recess 18 corresponding to the position of the through holes 16 . The base u is provided with a plurality of positioning grooves 19 on the step portion 15 200907354. 5 15 The probes 2 are a spring pin having two elastic needle bodies 24 at both ends of the outer casing 22, The peripheral edge of the outer rim is formed with respect to each of the elastic needles 24 - a shoulder surface 23 21 is inserted into the perforations 16 , and the shoulder surface of the bottom end of the outer casing 22 is at the top of the small diameter portions 17 The edge of the elastic needle body 24 extends out of the bottom surface of the base 11. Among them, the probe 2 L _ ', is a well-known, and its detailed structure is not described. The guiding block 3 has a plurality of guiding holes 32, and each of the guiding holes 3 has a peripheral wall extending to form a small-diameter portion 33, and the guiding block 3 is placed at the step 2 15 , and the guiding holes 32 are placed on the upper part of the probes 21 and the sub-surface 23 is abutted against the small-diameter parts of the top surface 23 of the outer casing 22: The top end of the needle body 24 protrudes from the top sill guiding block 31 of the guiding block 31. At least the fixing bolt is fixed at the step portion 15. The guiding block is used to fix the guiding block 34. 31 is fixed at the step ~ and each port of the Xuankou Yucai 34 is a bolt. The guiding block 31 is provided with a plurality of holes 36 through which the plurality of positioning posts 37 are inserted and inserted into the positioning slots 19 Θ '. The guiding blocks 31 can be accurately determined by the positioning posts 37. Positioned on the base 11. The position of the bottom surface of the guiding block corresponding to the guiding holes 32 is concavely formed to form an upper concave portion. The cover plate 41' is a circuit board which is disposed on the base u, and the (four) pin 21' core transmits a signal. In this embodiment, the fixing bolt 42 is locked to the base. The fixing portion 12 of the seat is covered by the above-mentioned structure 'the cover plate 41 is covered by the probes 21, and since the 20 200907354 the seesaw 41 itself is a circuit board, a detecting circuit or a detecting circuit can be disposed on the detecting cover 41 or Related electricity: raw = 兮 and the bottom of the wooden needle 21 contact panel or object to be tested (the figure is not stalked by the test. At the same time 'the probe 21 is fixed by the guide block and the perforation 16 Will shift when testing.
欲更換探針21時，僅需將該蓋板41及引導塊31取下， 再拔出故障的探針21，接著再將新的探針21插入對應 弓丨孔32以及穿孔16，在蓋回該驗41後，即完成更換。 而其中’該上凹部38以及該下凹部18主要是為了減 少該基座11以及該導引塊31的局部厚度，如此一來可以 縮短該料引孔32減該等穿孔16的長度，進而減少了 該等探針21表面與該等導引孔32的孔壁以及該等穿孔16 的孔壁之間的磨擦面積，使針21可更容易的拔出或插 入，換言之’更換探針21即更為容易。When the probe 21 is to be replaced, only the cover 41 and the guide block 31 are removed, and the faulty probe 21 is pulled out, and then the new probe 21 is inserted into the corresponding bow hole 32 and the through hole 16 in the cover. After returning to the test 41, the replacement is completed. Wherein the upper concave portion 38 and the lower concave portion 18 are mainly for reducing the partial thickness of the base 11 and the guiding block 31, so that the material guiding hole 32 can be shortened to reduce the length of the through holes 16, thereby reducing The surface of the probe 21 and the wall of the hole of the guide hole 32 and the wall of the hole of the hole 16 allow the needle 21 to be easily pulled out or inserted, in other words, the replacement of the probe 21 It's easier.
另外，由於該等探針21的兩端仍然是插置於該等穿孔 16以及該等導引孔32 ’因此仍然受到該導引塊31以及該 基座11的良好固定，不會在檢測時移位。 200907354 【圖式簡單說明】 第一圖係本發明一較佳實施例之組合立體圖。 第二圖係本發明一較佳實施例之分解立體圖。 第三圖係本發明一較佳實施例之部分構件組合圖，顯 5 示探針置於基座之狀態。 第四圖係本發明一較佳實施例之俯視圖。 第五圖係沿第四圖中5-5剖線之剖視圖。 【主要元件符號說明】 10 10探針組具 11基座 12固定部 14延伸部 15階部 16穿孔 17小徑部 18下凹部 19定位槽 21探針 22外殼 23肩面 24彈性針體 15 31導引塊 32導引孔 33小徑部 34固定栓 36定位孔 37定位柱 38上凹部 41蓋板 42固定螺栓 8In addition, since the two ends of the probes 21 are still inserted in the through holes 16 and the guiding holes 32', they are still well fixed by the guiding block 31 and the base 11, and are not detected.
