The measuring wire is welded with the conductive base block; the conductive base block is fixed at a lower jaw of the crocodile clip body and is used as a lower platform for clamping a cable wiring terminal; and the conductive upper-portion block is fixed at an upper jaw of the crocodile clip body and is used for clamping a conductive upper support body of the cable wiring terminal. A groove is arranged at the conductive upper-portion block; and a projection block is arranged at the conductive moving block, wherein the groove is cooperated with the projection block. Rotating pin holes are arranged at the conductive upper-portion block and the conductive moving block; and the rotating pin is inserted into the rotating pin hole. According to the invention, the provided crocodile clip has the advantages of simple principle, convenient usage, reliable working, improved reliability of detected data, and improved product quality. The crocodile clip can be universally applied to circuit detection of a cable used in an electrical circuit and a crimping wiring terminal in other industries.
Description
Technical field
The present invention relates to a kind of cable connecting terminal conductivity detection crocodile clip, belong to electric detection apparatus technical field.
Background technology
Railcar is because single-unit length is long, and vehicle mesohigh equipment disperses, and vehicle operating is in the state of jolting for a long time in addition, is the reliability of guaranteeing to be electrically connected, and the two ends of mesohigh equipment room cable adopt cold pressing connection terminal to connect.Equipment installation, cable distribution, terminal compression joint are complete all will to be detected afterwards to all cables, uses conventional crocodile clip clamping cable connecting terminal to be connected to cable tester in the past and detects.Conventional crocodile clip all has sharp metal sawtooth, when there is following defective in the crocodile clip clamping cable termination period of the day from 11 p.m. to 1 a.m: the metal sawtooth of (1) crocodile clip is applicable to clamp the multiply copper core of cable, and be not suitable for the parallel metal surface of clamping as binding post, so conventional crocodile clip is connected the risk that existence comes off with binding post in testing process; (2) the metal sawtooth of crocodile clip and cable termination sub-surface are Multi-contact, and contact resistance is large, affects testing result; (3) when connecting and remove crocodile clip, the metal sawtooth that crocodile clip is sharp can destroy the metal coating of cable termination sub-surface, and there is the oxidation risk in impaired place, and affects outward appearance.
Summary of the invention
Goal of the invention: technical problem to be solved by this invention is, but a kind of clamping different-thickness simple in structure, low contact resistance, the firm cable connecting terminal of clamping conductivity detection crocodile clip is provided.
Technical scheme: adopt following technical scheme for solving the problems of the technologies described above the present invention: a kind of cable connecting terminal conductivity detection crocodile clip, it comprises slotted line, crocodile clamp, conduction sole piece, conduction upper mass, conduction motion block, rotational pin, slotted line and the welding of conduction sole piece, the conduction sole piece is fixed on the upper lower platform as the clamping cable connecting terminal of lower crocodile of crocodile clamp, and the conduction upper mass is fixed on the upper crocodile of crocodile clamp upward as clamping cable termination electronic conduction upper support body; The conduction upper mass is provided with a groove, and the conduction motion block is provided with a projection, and groove cooperates with projection; Conduction upper mass, conduction motion block all are provided with the rotation pin-and-hole, and rotational pin inserts and rotates in the pin-and-hole.
Described conduction motion block is processed with the cylinder of a projection, and the conduction sole piece is provided with a circular hole, and the cylinder of projection is corresponding with circular hole.
Beneficial effect: (1) is of the present invention simple in structure, and conduction sole piece, conduction upper mass, conduction motion block, rotational pin, crocodile clamp are easy to assembly.(2) conduction motion block small cylinder is selected the 6mm diameter, and during use, crocodile clip can cover present railcar all size round cable binding post.(3) the conduction sole piece can be selected copper material, excellent conductivity, and conduction upper mass, conduction motion block can be selected steel or aluminium, adopt casting structure, process cheap.(4) machine work making assembling parts is on probation in the present invention, and result of use has obtained confirmation.
Description of drawings
Fig. 1 is the structural representation that cable connecting terminal of the present invention is used the conductivity detection crocodile clip.
Fig. 2 is the structural representation of conduction upper mass among the present invention.
Fig. 3 is the structural representation of conduction motion block among the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done further explanation.
As shown in Figure 1 to Figure 3, cable connecting terminal of the present invention comprises slotted line 1, crocodile clamp 2, conduction sole piece 3, conduction upper mass 4, conduction motion block 5, rotational pin 6 with the conductivity detection crocodile clip, slotted line 1 and 3 welding of conduction sole piece, specifically can weld with scolding tin, the conduction sole piece is communicated with the cable detection device port; Conduction sole piece 3 is fixed on the upper lower platform as the clamping cable connecting terminal of lower crocodile of crocodile clamp 2, guarantees to conduct electricity sole piece and cable connecting terminal interplanar to have large contact area, reduce contact resistance; Conduction upper mass 4 is fixed on the upper crocodile of crocodile clamp 2 upward as clamping cable termination electronic conduction upper support body; Conduction upper mass 4 is provided with a groove 41, and conduction motion block 5 is provided with a projection 51, and groove 41 cooperates with projection 51, and groove 41 is convenient to projection 51 combinations with conduction motion block 5; Conduction upper mass 4, conduction motion block 5 all are provided with and rotate pin-and-hole 7, and rotational pin 6 inserts and rotates in the pin-and-hole 7.
The ingenious utilization conduction of the present invention motion block links structure with conduction upper mass strand, conduction motion block and conduction upper mass are relatively rotated, the in opposite directions plane of the conduction motion block that makes crocodile clip and conduction sole piece is with the different adjustment of binding post thickness, guarantee that the in opposite directions plane of conducting electricity motion block and conducting electricity sole piece is in parastate, and compress in opposite directions.The small cylinder of the conduction motion block of crocodile clip embeds in the cable connecting terminal circular hole, and crocodile clip can not break away from from binding post in the testing process.Because crocodile clip conduction sole piece and binding post plane contact have reduced contact resistance, improve the whole detection precision.
The present invention is designed to the great advantage simple and ingenious structure, for different specification size cable connecting terminal highly versatile.
The above only is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
