Abstract
The utility model provides a protective testing rod with a concealed probe, which belongs to the technical field of electronic components. The utility model mainly comprises a rod body and a testing probe with one end arranged in the rod body and the other end extended outside the rod body. The utility model is characterized in that the rod body is provided with an elastic returning mechanism and an insulating protecting cover connected with the elastic returning mechanism, and the testing probe is sheathed in the insulating protecting cover. The probe overcomes the resistance of the elastic returning mechanism and extends towards the welding point to be tested in the protecting cover to complete the testing. The utility model has the advantages of accurate pointing, high stability and safety and can replace the existing naked centre type testing probe.
Description
The utility model relates to the testing tool of electronic equipment.
The measuring sonde of existing test electronic devices and components is the exposed shape of top formula, when measuring, because miniaturization day by day, the densification of electronic devices and components, distance between each solder joint or each the electric pin is very little, the test probe poor stability of top formula slides easily, makes probe run into the solder joint that should not contact or draw foot, cause test data inaccurate, or take place to connect the pin short circuit, burn out components and parts even have an accident.
For overcoming a fast shortcoming, Chinese patent ZL92216594.7 (No. the 19th, Patent Gazette for Utility Models the 9th volume) discloses a kind of " anti-slip complementary type contact ", it is characterized in that changing the top formula structure of tradition probe into be complementary type with solder joint concave structure form, contact is withheld and make it unlikely slip on solder joint during test.Though this complementary type contact can solve sliding problem, its contact that is exposed shape also can be run into the contiguous place that should not brush up against and causes test inaccurate or connect phenomenon such as pin short circuit equally when test because of waving inclined to one side material or rocking.
The purpose of this utility model provide a kind of test contact accurately, good stability, the built-in protection type prod of safe and reliable probe.
Formation of the present utility model comprises that a prod barred body and one one end are located in the barred body; the other end is stretched the test probe outside barred body; also be provided with an elastic recoil mechanism and an insulation protective jacket that is connected with this elastic recoil mechanism in described barred body, described test probe is sleeved in the insulation protective jacket.The external part of this protective sleeve is longer than the external part of test probe, and the test lead of test probe is contained in protective sleeve.When test, withhold earlier on the survey solder joint by the protective sleeve front end of insulativity, with contiguous solder joint formation insulativity packing; In protective sleeve, stretch to tested solder joint by probe again and finish test, fundamentally avoided false touch.
Described probe can be by being realized by the version of insulation protective jacket with respect to probe movement to the motion of stretching to of measuring point: it is affixed with barred body to pop one's head in; one end and the elastic recoil mechanism of insulation protective jacket join; press down barred body and make insulation protective jacket overcome the elastic force of elastic recoil mechanism and in barred body, bounce back, touch mutually with measuring point up to probe.
Also can insulation protective jacket and barred body is affixed, probe joins with elastic recoil mechanism, and be provided with one radially operating knob stretch outside barred body, make probe stretch to measuring point to finish measurement by pressing down operating knob with respect to the protective sleeve motion.
The accurate positioning of the utility model measuring point, contact stabilization is good, probe be built in finish in the insulation protective jacket measurements, test finish the back along with the release of slightly putting forth effort freely return in insulation protective jacket, safety, reliably.
Provide embodiment below in conjunction with accompanying drawing.But and the content of utility model is not limited in described embodiment.
Fig. 1 is the structural representation of embodiment 1
Fig. 2 is the structural representation of two-segment type protective sleeve
Fig. 8 is the test mode synoptic diagram
Fig. 4 is the structural representation of embodiment 2
Embodiment 1:
Referring to Fig. 1, the barred body of present embodiment is connected and composed by upper shell 2, lower house 5 usefulness screw rods 3, and probe 6 is fixed on the screw rod 3, and upper end and lead 1 join.Elastic recoil mechanism 4 can adopt the common version as flexure strip, spring and so on, and what select for use in the present embodiment is the stage clip of being convenient to install, and apical grafting is between screw rod 3 and insulation protective jacket 7.Insulation protective jacket 7 can be made by the rigid plastic tubing, and the length of its external part slightly is longer than probe 6, and the test lead of probe is ensconced in the protective sleeve.The front end of protective sleeve with make transparence for well, so that see the contact condition of probe and test point intuitively.Perhaps open a watch window 8 for now looking in its end.
Also protective sleeve 7 can be designed to two-segment type,, can simply adopt stationary fit to connect and compose referring to Fig. 2.The advantage of the protective sleeve of this two-segment type is except that can damaging the replacing, and also the situation of visual measured point is selected suitable protective sleeve front end for use.
Consider the abrasion or the damage of protective sleeve leading section, a spacing swivel nut 9 can be set in barred body, regulate the elongation of protective sleeve 7 by the position of Adjusting bolt Adjusting screw 9 and be longer than probe 6.
At first be that protective sleeve 7 is withheld on the measured point during measurement; referring to Fig. 3; slightly put forth effort on barred body again; 7 of protective sleeves overcome the resistance of stage clip 4 and move upward with respect to probe and barred body under the effect of the reacting force of measured point; promptly bounce back in barred body, just the barred body band the direction motion of the past measured point of probe until touching mutually with the measured point.
Embodiment 2:
The structure of present embodiment is basic identical with embodiment 1.Different is that its protective sleeve 7 is fixed in the barred body, and referring to Fig. 4, probe 11 and operating knob 12 and stage clip 4 that stretch barred body outside that radially be provided with by one join.By making probe 11 descending the touching mutually of resistance that overcome stage clip 4 finish test by operating knob 12 down with the measured point.
Claims (6)
1, the built-in protection type prod of a kind of probe; comprise that prod barred body and one one end are located in the barred body, the other end stretches out the test probe outside barred body; it is characterized in that also being provided with in the described barred body elastic recoil mechanism and an insulativity protective sleeve that is connected with this elastic recoil mechanism, described test probe is sleeved in the insulativity protective sleeve.
2, the built-in protection type prod of probe as claimed in claim 1 is characterized in that described insulation protective jacket and barred body are affixed, the probe with elastic recoil mechanism join and be provided with one radially operating knob stretch outside barred body.
