Claims
- 1. A connecting apparatus adapted to be electrically connected with a device to be tested, the device having a plurality of electrode portions, the connecting apparatus comprising:
- a base plate, one face of said base plate including a conductive portion formed thereon;
- a plurality of probes, each electrically connecting said electrode portions and said conductive portion; and
- an assembling equipment for assembling said probes in parallel into said base plate,
- wherein each probe includes a deformed portion, a needle front portion continuous with one end of said deformed portion, said needle front portion having a needle tip to be pressed against each of the electrode portions of the device; and a needle tail portion continuous with the other end of said deformed portion, and
- wherein said assembling equipment is provided with a retraction preventive portion for preventing said probes from retracting, and an elastically deformable needle presser portion to be in contact with said deformed portions or said needle tail portions of said probes, and said probes bring said tail end portions into contact with said retraction preventive portion.
- 2. A connecting apparatus according to claim 1, wherein each of said probes has an outside region extending in an arc-like shape to contact said conductive portion when each of said electrode portions is pressed by each of the needle tips.
- 3. A connecting apparatus according to claim 2, wherein a portion of each of said outside regions in contact with said conductive portion is adapted to shift along the probe toward said needle tip side as said electrode portion is pressed by said needle tip with greater force.
- 4. A connecting apparatus according to claim 3, wherein said assembling equipment is provided with one or more covers assembled into said base plate and has a recess extending in the arranging direction of said probes and said retraction preventive portion, said recess opening at the side of said base plate, said assembling equipment being further provided with one or more needle pressers having said needle presser portion extending in the arranging direction of said probes.
- 5. A connecting apparatus according to claim 2, wherein said assembling equipment is provided with one or more covers assembled into said base plate and has a recess extending in the arranging direction of said probes and said retraction preventive portion, said recess opening at the side of said base plate, said assembling equipment being further provided with one or more needle pressers having said needle presser portion extending in the arranging direction of said probes.
- 6. A connecting apparatus according to claim 1, wherein each of said probes includes a rear end face in contact with said retraction preventive portion.
- 7. A connecting apparatus according to claim 1, wherein said assembling equipment is provided with one or more covers assembled into said base plate and has a recess extending in the arranging direction of said probes and said retraction preventive portion, said recess including an inner face and an opening at the side of said base plate, said assembling equipment being further provided with one or more needle pressers having said needle presser portion extending in the arranging direction of said probes.
- 8. A connecting apparatus according to claim 7, wherein each of said one or more covers is further provided with a plurality of slots arranged at intervals in the longitudinal direction of each of said one or more needle pressers, said plurality of slots opening at the sides of said base plate and said device to be tested communicating with said recess, and
- wherein the needle front portion of each probe penetrates said slot to project its needle tip out of said slot.
- 9. A connecting apparatus according to claim 7, wherein said retraction preventive portion includes the inner face of said recess.
- 10. A connecting apparatus according to claim 7, wherein each of said one or more covers is further provided with a plurality of slots opening at the side of said base plate, each of said slots including an end face and communicating with said recess and arranged at intervals in the longitudinal direction of each of said one or more needle pressers, and
- wherein each probe is received in said slot at a part of said deformed portion.
- 11. A connecting apparatus according to claim 10, wherein said retraction preventive portion includes the inner face of said recess or the end face of each of said slots.
- 12. A connecting apparatus according to claim 7, wherein said assembling equipment is further provided with a stopper disposed in each of said covers so as to form said retraction preventive portion.
- 13. A connecting apparatus comprising:
- a base plate having a plurality of conductive portions on one face;
- a plurality of probes for electrically connecting electrode portions of a device to be tested and said conductive portions, respectively; and
- an assembling equipment for assembling said probes in parallel into said base plate,
- wherein each probe is provided with a curved deformed portion, a needle front portion continuous with one end of said deformed portion and having a tip end to be pressed against each of the electrode portions of the device to be tested, and a needle tail portion continuous with the other end of said deformed portion, and
- wherein said assembling equipment includes a retraction preventive portion for preventive said probes from retracting, and an elastically deformable needle presser portion in contact with said probes so as to bring at least a part of each of said deformed portions or said needle tail portions into contact with said conductive portions, respectively, said probes bringing said tail end portions into contact with said retraction preventive portion.
