Abstract
The utility model discloses a test needle with cylindrical measuring head, including sleeve pipe, elasticity set up in the cylindrical measuring head of sleeve pipe one end, cylindrical measuring head includes the edge the reference test bar that sleeve pipe length direction slided and sets up, and set up the measuring head of reference test bar tip, the measuring head is the cylinder setting, just V -arrangement recess, syntropy setting have been seted up with great ease to the test face of measuring head crossing setting of between adjacent sidewalls between the V -arrangement recess, just edge's circumference equipartition all around of the test face of measuring head has the inclined plane. This structural design through the V -arrangement recess of seting up with great ease, effectively increases the frictional force that the face was tested to the measuring head for can with the stable contact of solder joint, in addition, measuring head that the cylinder set up has increased the area of measuring head test face, makes with the solder joint contact more reliable and more stablely.
Description
Technical field
This utility model relates to circuit board testing technical field, particularly relates to a kind of testing needle with cylindrical measuring head.
Background technology
Under prior art when solder joint bigger on pcb board is tested, sphere convex shape is the most all become due to solder joint, therefore common test pin is difficult to reliable and stable contacting, and when test, is easy to so that needle section sideslip bending because the area of needle section test surfaces is less.
Utility model content
This utility model provides one can be effectively increased syringe needle test surfaces area, improves the testing needle of measuring stability.
For reaching this purpose, this utility model by the following technical solutions:
A kind of testing needle with cylindrical measuring head, including sleeve pipe, the cylindrical measuring head that is flexibly set in described sleeve pipe one end, described cylindrical measuring head includes the reference test bar arranged along the slip of described casing length direction, and it is arranged on the measuring head of described reference test bar end, described measuring head is that cylinder is arranged, and the test surfaces of described measuring head offers v-depression in length and breadth, adjacent wall between the described v-depression arranged in the same direction intersects setting, and the edge of the test surfaces of described measuring head is evenly distributed in inclined plane.
Wherein, the diameter of described measuring head is more than the diameter of described reference test bar.
Wherein, described inclined plane is set to four and intersects setting successively.
Wherein, the other end of described sleeve pipe is provided with fixing bar.
The beneficial effects of the utility model: this utility model includes sleeve pipe, is flexibly set in the cylindrical measuring head of described sleeve pipe one end, described cylindrical measuring head includes the reference test bar arranged along the slip of described casing length direction, and it is arranged on the measuring head of described reference test bar end, described measuring head is that cylinder is arranged, and the test surfaces of described measuring head offers v-depression in length and breadth, adjacent wall between the described v-depression arranged in the same direction intersects setting, and the edge of the test surfaces of described measuring head is evenly distributed in inclined plane.This structure designs, and by the v-depression offered in length and breadth, is effectively increased the frictional force of measuring head test surfaces, make it possible to stably contact with solder joint, additionally, the measuring head that cylinder is arranged, add the area of measuring head test surfaces so that contact more reliable and more stable with solder joint.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of testing needle with cylindrical measuring head of this utility model.
Fig. 2 is the axonometric drawing of cylindrical measuring head in Fig. 1.
Detailed description of the invention
Shown in 1 to accompanying drawing 2 and further illustrate the technical solution of the utility model by detailed description of the invention below in conjunction with the accompanying drawings.
A kind of testing needle with cylindrical measuring head, including sleeve pipe 1, the cylindrical measuring head that is flexibly set in described sleeve pipe 1 one end, described cylindrical measuring head includes the reference test bar 21 arranged along the slip of described sleeve pipe 1 length direction, and it is arranged on the measuring head 22 of described reference test bar 21 end, described measuring head 22 is arranged in cylinder, and the test surfaces of described measuring head 22 offers v-depression 23 in length and breadth, adjacent wall between the described v-depression 23 arranged in the same direction intersects setting, and the edge of the test surfaces of described measuring head 22 is evenly distributed in inclined plane 24.
It is further preferred that the diameter of described measuring head 22 is more than the diameter of described reference test bar 21.This structure designs, it is possible to be effectively increased the area of the test surfaces of measuring head 22, improves measuring stability.
It is further preferred that described inclined plane 24 is set to four and intersects setting successively.Preferably, inclined plane 24 is the chamfering being arranged at cylinder test surfaces end, the design of this structure, it is possible to make to form sharp cusp between the v-depression 23 of edge, it is simple to effectively contact with solder joint.
It is further preferred that the other end of described sleeve pipe 1 is provided with fixing bar 3.As preferably, this structure is identical with ordinary elasticity testing needle structure, and is provided with the spring slided for reference test bar 21 in sleeve pipe 1, does not repeats at this.
Know-why of the present utility model is described above in association with specific embodiment.These descriptions are intended merely to explain principle of the present utility model, and can not be construed to the restriction to this utility model protection domain by any way.Based on explanation herein, those skilled in the art need not pay performing creative labour can associate other detailed description of the invention of the present utility model, within these modes fall within protection domain of the present utility model.
