Specific embodiment
The core of the present invention be provide a kind of earth detector, this earth detector can under different operating modes safety
Efficiently implement detection of electrical leakage.
In order that those skilled in the art more fully understand the present invention program, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
Refer to Fig. 1 to Fig. 3, the detection of the earth detector that Fig. 1 is provided by a kind of specific embodiment of the present invention
The structural representation of terminal part；The installation of the earth detector that Fig. 2 is provided by a kind of specific embodiment of the present invention connects
The structural representation that head divides；The control terminal of the earth detector that Fig. 3 is provided by a kind of specific embodiment of the present invention
Partial structural representation.
In a specific embodiment, earth detector provided by the present invention, including detection terminal, insulation extension rod with
And the control terminal with detection terminal wireless communications, it is connected with erection joint between detection terminal and insulation extension rod；Detection terminal
Including body 11, the middle part of body 11 is provided with detection module 111, and the leading section of body 11 can be opened and closed to be provided with clamp 112,
It is connected with return unit 113 between two caliper inner ends of clamp 112；Control terminal includes palm machine 13, palm machine 13 is provided with aobvious
Display screen 131 and keyboard 132.
During assembling uses, under general operating mode, staff only needs on clamp 112 clip to corresponding cable, you can
Implement the detection of electrical leakage of corresponding cable by the wireless cooperation between detection terminal and control terminal；When needing to higher position or not
When easily directly the equipment of the enforcement special station of operation or cable implement detection of electrical leakage, by erection joint, detection terminal is reliably pacified
It is loaded on the front end of insulation extension rod, so that staff can extend rod rear end by gripping insulation and deliver to relatively detection terminal
The detection station of high position implements detection of electrical leakage.Described earth detector disclosure satisfy that the power equipment of high-order or special station
Or cable detection of electrical leakage operation, it is to avoid the work high above the ground of staff or step on the dangerous larger operation such as bar operation, thus
Greatly reduce the labor intensity of staff, improve detection of electrical leakage safety, and its operating process is simple and easy to do, detection effect
Rate is higher.
Additionally, return unit 113 can provide suitable reset clamping force for the caliper of clamp 112, to ensure clamp 112
Stable fully clamping adaptation between two calipers.
Further, erection joint includes front connector 121 and coaxial package in the rear joint 122 at front connector 121 rear portion,
The leading section of front connector 121 has along its axially extended front screw 123, and the rearward end of detection terminal has and front screw 123
The stud 114 of screw thread cooperation, the rearward end of rear joint 122 have along its axially extending and with insulation extension rod screw thread cooperation after
Screw 124.During practical operation, this kind of screw thread structure that is connected can effectively ensure that erection joint and detection terminal and prolongation
Assembly reliability between bar, and the dismounting of screw connection structure is relatively simple, can improve the behaviour of earth detector further
Make efficiency.
More specifically, locking hole 125 is had on the leading section side wall of rear joint 122, the middle part both sides setting of front connector 121
There is the bayonet lock 126 being adapted to locking hole 125 clamping.During assembling, bayonet lock 126 is snapped in locking hole 125, so that front connector 121
To between rear joint 122 reliable clamping assembling fixing it is ensured that the assembling intensity of whole erection joint and its related counterpart and reliability
Property.
Additionally, locking hole is " l " shape hole.After this kind " l " shape hole makes bayonet lock 126 snap in vertically in locking hole 125, then
Turn an angle circumferentially opposed between rear joint 122 and front connector 121, so that the radial direction that bayonet lock 126 snaps in locking hole 125 is prolonged
In exhibition section, thus avoiding bayonet lock 126 after the completion of assembling that axially opposing movement or dislocation will not be occurred and between locking hole 125 even de-
The phenomenon such as fall.
On the other hand, the sidepiece of detection terminal has side screw 115, is fitted with and this side screw 115 spiral shell in side screw 115
The regulation spanner 116 of stricture of vagina cooperation, the inner end adjusting spanner 116 is matched with the caliper inner end of clamp 112.Practical operation
When, when needing to open clamp 112 under larger angle or special operation condition demand, staff screws regulation spanner 116, so that its
Stretch in body 11 and the caliper inner end contacts side surfaces with clamp 112, continue to screw regulation spanner 116 so as to pincers afterwards
Internal end applies horizontal force, so that caliper overcomes the reset force of return unit 113 to be flared to suitable angle, to implement
Corresponding operation, after the completion for the treatment of operation, reversely screwing regulation spanner 116 makes it disengage with the caliper of clamp 112, you can make pincers
Body resets in the presence of return unit 113.
In addition, return unit 113 is spring.The structure of spring is simple and active force conduction is uniform and stable.Can effectively ensure that
The reliability of the related folding operation process of clamp 112 and working performance.
Additionally, the caliper leading section of clamp 112 has curved guiding surface 116.This curved guiding surface 116 can make cable more suitable
Freely sliding and snap between two calipers of clamp 112, and detach described earth detector after the completion of operation can make cable by leading
Skid off the jaw of clamp 112 at cambered surface 116, thus improving the operating efficiency of described earth detector further, reduce it
Operation easier.
In summary, in the present invention provide earth detector, include detection terminal, insulate extension rod and with detection
The control terminal of terminal wireless connection, is connected with erection joint between described detection terminal and described insulation extension rod；Described detection
Terminal includes body, and the middle part of described body is provided with detection module, and the leading section of described body can be opened and closed to be provided with clamp,
It is connected with return unit between two caliper inner ends of described clamp；Described control terminal includes palm machine, and described palm machine is provided with
Display screen and keyboard.During assembling uses, under general operating mode, staff only needs on clamp clip to corresponding cable, that is,
