The inspection jig is provided with a pin plate 2 (pinb〇ard) 2; a spacer board 4 disposed on the surface side of the pin plate 2, and a protection plate 6 disposed on the surface of the spacer plate 4 The probe body 8 is electrically connected to the terminal portion of the printed wiring board to be inspected. The probe body 8 is attached to the pin plate 2. The probe body 8 is configured as: an outer sleeve 1〇, mounted on the pin plate 2, and an inner sleeve 12 disposed on the inner side of the outer sleeve 1〇; a coil spring 14 received in the inner sleeve 12 And the probe pin 16 is received in the front end side of the inner sleeve 12; the front end side of the probe pin 16 protrudes outward through the guide hole 18 formed in the protective plate 6, and the projection utilizes the coil spring U The elastic restoring force is electrically connected to the terminal portion of the printed wiring board. The above-mentioned inspection jig ' is configured such that the inner sleeve can be removed from the outer sleeve j. Therefore, when the probe pin 16 is worn, the old inner sleeve 12 can be removed and the new one can be attached. The coil spring 14 and the probe pin 16 arranged in the inner sleeve 12 are replaced. However, in the inspection jig, the inner sleeve 12 is disposed on the inner side of the outer sleeve 10 in the direction of the outer sleeve 10, and the coil magazine 14 is folded inward in the radial direction of the 拙 娃 园 佐 佐 η 恻砮 恻砮 12 Further, the outer diameter of the probe pin 16 is increased, and the outer diameter of the probe body 8 318170 5 1323785 is increased, and the problem of an increase in the printed wiring board in recent years cannot be sufficiently satisfied. - (4) Solving the above problem 'The inspection clip shown in Fig. 7 has been proposed., (for example, ~, Japanese Patent Document i). The inspection jig includes: a lower pin plate 22; and an upper pin plate 24 disposed on an upper side of the lower pin plate 22; and a differential hole attachment hole in the staple plate 22 26' The attachment hole 26 is provided with a probe pin 28, and the small projection 3 of the probe insertion pin (the M system protrudes outward from the lower pin plate 22. In addition, the upper probe plate 24 is also attached. An attachment hole 32 is provided with a stepped portion, and the attachment hole accommodating the lead wire with the coil spring 34' and the coil magazine 34 integrally formed is led out from the upper probe plate 24. The above inspection jig is The probe pin ^ itself is attached to the lower pin plate 22, and its outer diameter is small, so that the mounting degree of the probe pin 28 can be increased (in other words, the interval between the probe pins 28 is reduced). [Patent Document 1] JP-A-2000-227441 A SUMMARY OF THE INVENTION (Problems to be Solved by the Invention) However, the "inspection jig described above" has the following problems. The second embodiment has a configuration in which the lower pin is formed. The plate 22 is provided with a bracket differential attachment hole 26 for receiving the probe pin 28, but the attachment of the attachment differential attachment hole 26 is not easy, and the inspection fixture is made The manufacturing cost becomes high, and in particular, in the case of a type in which a plurality of probe pins 28 are attached, the cost is greatly increased. Second, the probe pins 28 are configured to be accommodated in the lower pin plate 22 The step portion is attached to the hole 26, and therefore, when the probe pin 28 is to be replaced by wear or the like, it is necessary to "318170 6 丄JZ:)/6:) the upper pin plate 24 must be inserted from the lower side first. The plate 22 can be replaced only after it is removed, resulting in a very complicated replacement of the probe pins 28. SUMMARY OF THE INVENTION An object of the present invention is to provide an inspection jig for a printed wiring board which can hold a probe pin as desired, and which can be easily replaced, and can also be adapted to a high distribution of a printed wiring board. (Means for Solving the Problem) The heart-shaped jig of the printed wiring board according to the first aspect of the present invention is characterized in that: the pinch plate includes a receiving hole and an attaching hole; and the protective plate is disposed on a single-side of the pin plate includes a guide hole; the probe pin is inserted into the attachment hole of the pin plate, and a distal end portion thereof protrudes outward through the guide hole of the protection plate; and the spring member is housed in The receiving hole of the pin plate is in the base of the probe pin.插 中 中 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插 插At the same time, the needle plate is also guided to the guide hole of the protective plate. In the printing jig according to the second aspect of the invention, in the inspection jig of the road plate, the pin plate includes: a lower pin plate provided with the receiving hole; and an upper side of the pair of upper pin plates And the device is provided with the above-mentioned device: the lower member is formed of a rubber plate and the rubber is sandwiched between the upper pin plates.

In the inspection jig of the present invention, the spring member is printed by the line = description, and the lead is mechanically disposed on the coil spring. In the scope of the patent application of the present invention, the fifth member of the present invention is formed by the end portion of the aforementioned lead of the coiled two of the coils. In the inspection jig of the patented circuit board of the present invention, the printing pin of the probe pin f is the same as that of the needle body provided at the end of the pin body. The function of the elastic force of the loop between the pin body and the small-diameter protrusion is small: == the inner peripheral surface of the end of the coil spring. The support line described in the first aspect of the invention is a printed circuit as described in the first aspect of the invention. The member is elastically held by the outer peripheral surface of the probe pin, so that the axial direction of the probe can be allowed. The moving side is held as desired, and the probe pin can be held by the configuration even when the probe pins are inserted. In addition, since the base side of the probe (4) is held by the 318170 8 1323785 mounting hole, the front end side is guided to the guide hole of the protection plate, so that the probe pin can also be moved in the axial direction. Stability is reserved. Further, the probe pins can be easily and easily replaced, for example, by being formed in a straight line. Further, in the inspection jig for a printed wiring board according to the second aspect of the invention of the present invention, the pin plate is provided with a lower pin plate and a pair of upper pin plates, and Since the rubber sheet of the elastic grip member is disposed between the pair of upper pin plates, the rubber sheet can be surely supported while the structure of the elastic grip member is simplified. Further, according to the inspection jig of the printed wiring board described in claim 3 of the present invention, since the inner diameters of the attachment holes provided in the pair of upper pin plates are substantially equal, and the elasticity of the rubber sheet is obtained The holding portion protrudes inward in the radial direction from the attachment hole of the pair of upper pin plates, so that the elastic grip portion can be stably held and elastically held by the elastic pinch portion of the probe pin plate. Even when the probe pin is moved to the multi-movement, the rubber plate=elastic holding portion is hardly elastically deformed in the moving direction, so that the probe pin can be stably supported.

The printing range described in item 6 of the patent range, due to the pin body and small diameter of the probe pin The work of the receiving part: Part I and the shoulder is used as a spring for the coil spring. The contact state of the coil spring to the probe pin is stable, which can suppress the wear and tear of the coil spring. Further, since the probe pin projecting portion supports the coil spring end adjacent to the circumferential surface of the (10) (four) phase, when the additional force acts, the occurrence of buckling at the end of the coil spring is suppressed, and the life of the coil spring is prolonged.

The rubber sheet 134 is formed of an electrically insulating rubber material such as a kick, a synthetic rubber knee, and the like, and is sandwiched between a pair of upper pin plates 112 and 114. The rubber plate 134 is provided with a holding hole 13.6 for holding the probe pin 130, and defines a holding hole 136; the elastic holding portion 138 is a part of the rubber plate 134 and is located at the mounting hole; 122, 124 The inner portion is attached to the attachment holes 122 and 124 of the pair of upper pin plates 2 and 4, and protrudes slightly inward in the radial direction. The outer peripheral surface of the base portion side of the probe pin 130 is elastically held by the elastic grip portion 138 of the rubber sheet bundle 34, and the both side portions held by the elastic grip portion 138 are guided and held by the pair of upper pins. The attachment holes 122, 124 of the plates 112, 114 are guided to the guide holes 128 of the protection plate 1A6 at the front end side thereof. In this embodiment, both end portions of the probe pin 13A are formed into a tapered tapered shape, and the distal end portion of the tapered portion on the base side is housed in the coil as shown in FIG. 3 and FIG. In the end portion of the spring 132, the tapered surface abuts against the end surface of the coil spring 132. According to the above configuration, when a predetermined force or more is applied to the probe pin (3) in the direction indicated by the arrow p in the arrow (p), the coil spring 132 is compressed and the probe pin (10) is applied. Move to the lower direction of the axis, 'When the force is released, the coil spring force probe pin UG moves to the upper position in the axial direction and returns to the original position." When the probe is inserted, the probe pin 13° The upper holes 128, the p-shaped attachment holes 122, 124 of the p-type, and the guide holes 128 of the protective plate 106 are guided to a stable movement in the axial direction. ^, In the mode, as shown in Fig. 3, the coil spring 132盥 is formed into a body. The coil spring 132 can be formed of high strength with 318170 12 1323785 • conductive metal wire. The lead wire 14 extending from the coil spring 132 is led out to the outside through the lead-out hole 142 formed in the wiring board 116, and the front end of the lead wire 140 thus led out is soldered at the terminal provided on the wiring board 116. The isoelectric connection is fixed. By using the coil spring 132 which is just integrated with the lead wire, the electrical connection failure between the coil spring 132 and the lead wire 14 can be eliminated. This inspection jig 102 is used as will be described later. That is, as shown in Fig. i, 'the positional relationship of the printed road board 14 to be inspected is positioned on the upper side of the inspection jig 1〇2 using a positioning jig (not shown), and is mounted to push the protection board from the protection board. 106 protruding (four) probe material (10) before the end. In this way, the coil spring 132 is compressed, and the elastic force of the coil spring is used to force the probe pin 130 to be elastically pushed to the predetermined terminal portion of the printed circuit board 144, so that the terminal portion and the probe are The pin 13 () is indeed electrically connected. Therefore, the inspection of the printed wiring board 144 can be performed as desired by using the inspection jig (4) constructed as described above. • When the old probe pin 13 that has worn out, etc., is replaced with a new one, the tip end of the probe pin 13 that protrudes from the protective plate (10) is clamped (not shown) to Pull out in the clamped state. Since the probe insert 130 is linear and is only elastically held by the elastic grip portion 38 of the rubber sheet 134, the probe pin 130 can be easily removed from the pin plate by the pull-out method as described above. 104 removed. In addition, when the new probe pin 130 is mounted, the probe pin 13 is inserted into the upper pin plate 112, U4 of one of the pair of pin plates 104 through the guide hole I" of the protective plate 1〇6. It is sufficient to attach the holes 122, 124, and by inserting, the base side is covered by a rubber sheet (9)

In the above-described embodiment, in order to make the explanation simple and easy to understand, it is explained that a probe pin is attached from the stitch board 1〇4 applied to the inspection jig 1〇2, but the actual inspection jig is used. A plurality of, for example, 1000 to 5000 probe pins 13 are attached to the pin plate 1〇4, and in the case where a plurality of probe pins 130 are attached as described above, Since the probe pin 130 itself is attached to the pin plate 104, the interval between the probe pins 130 can be reduced, so that it can be conveniently applied to the inspection of a highly equipped printed circuit board. " ^ Figure 4 shows another embodiment of the connection structure of the coil spring and the lead. In this embodiment, the coil spring 132A and the lead u 〇 A are formed as different individual 'coil springs 132A' are formed by a common wire spring formed by conductive metal wires; for example, they are formed by enameled wires. The end portion is formed into a flange shape by press working, for example, and the flange head portion 152 is electrically connected to the end portion of the coil = spring 132A as shown in Fig. 4 . In this embodiment, the flange head portion 152 of the lead 140A is received in the receiving hole 118 of the lower pin plate 110, and the lead wire 140 extending from the flange head portion is led out through the wiring board 116. The hole 142 is led out to the outside, and the coil spring 132A is interposed between the flange head portion 152 and the probe pin 130. By using the above-described connection structure, the coil spring 132A can be surely electrically connected to the flange head shape 152 of the lead 140A. Figure 5 is a representation of the coil spring of the probe pin. 318170 14 !323785 Another embodiment. In this embodiment, the structure of the coil spring 132A and the lead wire 140A is substantially the same as that of the structure shown in Fig. 4, and only the probe pin 130B is corrected. In the probe pin 13B of the embodiment, the needle script body 162 having an elongated cylindrical shape is provided, and one end portion of the needle script body 162 is provided with a small-diameter protrusion 164 that protrudes outward in the axial direction. The outer diameter of the small-diameter protrusion 164 is smaller than the outer diameter of the needle script body 62. A shoulder portion 166 is provided between the needle script body 162 and the small-diameter protrusion portion ι64. Further, the small-diameter protrusion portion 16 is externally The diameter of the coil spring 丨3 2 A is small, and the small-diameter protrusion 丨 64 is inserted into the coil spring 132A and supports the inner peripheral surface of the end portion thereof. Further, the distal end portion of the small-diameter projection 64 is formed so as to be easily inserted into the coil spring 3 in a tapered shape, and the other end portion of the needle script body 162 is formed into a tapered shape as described above. In this embodiment, the shoulder portion 16 6 of the probe pin 13 functions as a spring receiving portion. Since the end portion of the coil spring 132A is received by the shoulder portion 166, the probe pin 130B and the coil spring 132A are The abutment between the ends _ the support is relatively stable. The wear of the coil spring 132A caused by the above movement of the probe pins 13 is suppressed. Further, since the small-diameter projection 164 of the probe pin 13A supports the inner peripheral surface of the end portion of the coil spring 132A, the occurrence of the curvature in the end portion of the coil spring 132A is suppressed. The life of the coil spring 132A can be extended. As described above, the embodiment of the inspection jig of the printed wiring board of the present invention will be described. However, the present invention is not limited to the embodiment, and various modifications and corrections are possible without departing from the scope of the invention. For example, in the above-described embodiment, although the pair of upper stitch plates 318170 15 have the rubber sheets 134 at intervals of the milk 785 112, 114, the present invention is not limited to this configuration, and for example, one of the upper pin plates 114 may be used. Occasionally, the rubber sheet 134 is sandwiched between the upper side pin plate 112 and the lower side pin plate 11 (). In the case of the above configuration, it is preferable to attach the upper side pin plate 112 to the hole. The inner diameter of 122 is substantially equal to the inner diameter of the receiving hole 118 of the lower pin plate 11 。.
