Description

A kind of socket joint type multitester probe

The utility model is a kind of multitester probe by socket join structure conversion measuring head, and it can adapt to the needs of various situations in the measurement.

Traditional multitester probe often runs into following two problems in measurement: the one, be difficult to adapt to the measurement of compact apparatus, particularly for the electronic equipment of miniaturization, it is very clumsy that its measuring head will seem, is easy to make short circuit between adjacent contact, causes and measure mistake or damage tested components and parts; The 2nd, can not carry out measuring point locking, easily cause measuring point slippage or loose contact, also decentralized measure energy easily makes the measurement can not be free and relaxed.In order to overcome the shortcoming of traditional multitester probe, Chinese patent ZL95219079 provides a kind of multitester probe of interchangeable measuring head, it has a movable refill that is contained on the penholder, its two ends have different measuring heads, and this movable refill has been realized the transposing of two ends measuring heads by screw thread on the penholder and hinge arrangement.Like this, just there have been 3～4 kinds of different measuring heads available in a pair of test pencil.Moreover, the situation that this patent also can not lock at intensive, the tiny characteristics of measuring point in the integrated circuit and measuring point and designed latch hook formula measuring head, the exhausted formula measuring head of measuring point edge, pin locate mode and measured first-class.Though this test pencil has solved the problem of above-mentioned traditional test pencil from principle, its structure is not really desirable, and part also comes with some shortcomings.Comparatively complicated such as: the transposing structure of measuring head, and operating cost time, inconvenience, can not reach quick transposing, operation condition freely.In addition, the structure specific aim of measuring head is strong excessively, so versatility is poor, the survey heavy current installation of can not holding concurrently simultaneously, also is unfavorable for the use habit that keeps traditional test pencil probe-type to measure.

The purpose of this utility model is in order to overcome the shortcoming of prior art, to provide a kind of simple in structure, easy to use, and can keep the socket joint type multitester probe of traditional measurement custom.

For achieving the above object, solution of the present utility model is as follows: it is made of the measuring pen and the measurement pen cap; Described measuring pen comprises that the main chaining pin that insulation penholder and are contained in this insulation penholder constitutes, and the syringe needle of described main chaining pin stretches out the front end of last words written before one's death bar, and this syringe needle front end is small-sized epiconus body, is provided with a necking segment in the middle part of this syringe needle; The described measurement pen cap is made of an insulating sleeve and a secondary chaining pin or a latch hook mechanism that is contained in this insulating sleeve front end, in described insulating sleeve, be provided with a conductor inner sleeve that matches with insulation penholder front end, the afterbody of the front end of this conductor inner sleeve and secondary chaining pin or latch hook is coupled as one, the middle part also is provided with a necking segment, the necking segment snap-fit on this necking segment and the main chaining pin head.

By above-mentioned solution as can be seen, measuring pen of the present utility model has adopted a kind of probe-type structure of miniaturization, the very thin dexterity of its chaining pin head, complete measurement requirement applicable to the miniaturized electric subset, during operation, still keep the probe-type of traditional test pencil to measure custom, usable range is wide, the influence that not tested dot structure changes, easy to operate, flexible.In order to satisfy the needs of various situations in the measurement, the utility model has adopted the conversion that can realize measuring head with the measurement pen cap that measuring pen connects together, its mapped structure is simple, processing ease, and after the socket, still can keep the globality of measuring pen and the measurement custom of probe-type preferably.By the conversion of measuring head, make the measurement range of this test pencil widen, the survey heavy current installation of can holding concurrently can also carry out the measuring point locking simultaneously.Therefore, superiority of the present utility model is that measurement range is wide, adapts to widely, simple in structure, easy to operate, flexible, meets the measurement custom of traditional test pencil, is easy to apply.

Describe its structure in detail according to embodiment below.

Fig. 1, one-piece construction cut-open view of the present utility model.

Fig. 2, the cut-open view of measuring pen.

Fig. 3, one of cut-open view of the measurement pen cap (the measurement pen cap of hook mechanism with lock).

Fig. 4, two (with the measurement pens cap of traditional chaining pin) of the cut-open view of the measurement pen cap.

Referring to Fig. 2, sequence number (1) is the insulation penholder of described measuring pen, and (2) are main chaining pins, and the syringe needle front portion of this main chaining pin is a small-sized epiconus body (2-1), and the syringe needle middle part is provided with the described strength section (2-2) that contracts.In order to adapt to the measurement of forceful electric power, further protect epiconus body (2-1), at the head of insulation penholder a conductor segment (3) with main chaining pin electric connection can be set.When measuring pen and the socket of measuring pen cover, as shown in Figure 1, this conductor segment (3) can be used as a split point of main chaining pin.The afterbody of described main chaining pin is electrically connected with lead (5) by contact (4).

Referring to Fig. 4, sequence number (6) is the insulating sleeve of the described measurement pen cap, and (7) are described secondary chaining pins.In order to adapt to the measurement of forceful electric power, this pair chaining pin has adopted the chaining pin head of traditional test pencil.Sequence number (8) is the described conductor inner sleeve that is located in the insulating sleeve, the afterbody of this inner sleeve have one with described insulation penholder on conductor segment (5) the tapered sleeve section (8-1) of sleeve contact matching mutually, the inner sleeve middle part also is provided with a necking segment (8-2), necking down (2-2) snap-fit on this necking down and the main chaining pin head.When this measurement pen cap and measuring pen connected together, as shown in Figure 1, conductor inner sleeve (8) electrically contacted with main chaining pin (2) by described necking down (8-2) and tapered sleeve section (8-1).When measuring heavy current, the electric current of the main chaining pin of process can flow to secondary chaining pin (7) by above-mentioned two contact points, thereby has avoided the damage of heavy current to main chaining pin head, protection epiconus body (2-1).

Referring to Fig. 4, have the function of measuring point locking in order to make measuring pen, at the front end of the insulation pen cap (6) described latch hook mechanism can be set, this latch hook mechanism is by hook-shaped chaining pin (9), the chaining pin pillar (6-1) that extends and be located at stage clip (10) formation in the insulation pen cap.When this measurement pen cap and measuring pen connect together, pull insulating sleeve and make it prolong penholder to retreat, then hook-shaped chaining pin head stretches out, and it is hooked in measure on the pin, loosen hand-power then, and then resilience under the effect of the pressure bullet of insulating sleeve forms the measuring point locking.
