Technical Field

[0001] The utility model relates to the technical field of signal line connection, in particular to a waterproof quick-connect device for connecting a signal line and a sensing probe. Background Art

[0002] As the power grid structure becomes increasingly complete, the application scenarios of electrical equipment become more and more complex, and the normalization of outdoor, coastal and offshore working conditions poses new challenges to the reliability of equipment wiring. In order to meet the needs of power grid development, the waterproof performance of the wiring of a single signal line directly derived from the primary equipment body needs to be further improved.

[0003] At present, the wiring of the live display probe position of existing combination electrical appliances is relatively difficult. The induced voltage signal of the built-in probe passing through the metal flange hole needs to be led out. The lead wire needs to be reliably connected in a limited space and the insulation between the lead wire and the hole wall must be ensured.

[0004] In the prior art, this position still uses the traditional clevis bolt crimping method, which has the following shortcomings:

[0005] 1. The traditional wiring method cannot achieve reliable insulation with the flange. When using the above wiring method, it is very easy to cause the wire head to overlap with the hole wall during wiring. At the same time, the water vapor in the threading tube is easy to condense in the wiring hole during evaporation, causing the insulation performance of the wiring to decrease or lose, resulting in signal reduction or loss.

[0006] 2. The traditional wiring method is not convenient enough. Since the wiring operation is carried out in a deep hole with a small diameter, the wiring steps are cumbersome, and direct wiring inspection is impossible. It needs to be verified through additional tests. The overall efficiency is low and does not meet the existing wiring needs. Utility Model Content

[0007] The purpose of the utility model is to overcome the shortcomings of poor insulation reliability and complicated wiring operation in the prior art, and to provide a waterproof quick-connect device for connecting a signal line and a sensing probe, which has a reasonable design, a simple structure, is easy to operate, and has a good waterproof effect. It can not only reduce the difficulty of wiring, but also ensure the reliability of wiring, and is suitable for promotion.

[0008] The utility model is realized by the following technical scheme: a waterproof quick-connect device for connecting a signal line and an induction probe, comprising a metal flange, a pipe joint, a signal line core and a signal line shielding layer, the pipe joint is connected to the metal flange, and a locking rubber pad is arranged between the pipe joint and the metal flange; a sealing rubber platform A which can be installed in the pipe joint hole is arranged on the top side of the locking rubber pad, a sealing rubber platform B which can be installed in the metal flange hole is arranged on the bottom side of the locking rubber pad, and threading holes are opened on the locking rubber pad, the sealing rubber platform A and the sealing rubber platform B; the locking rubber pad, the sealing rubber platform A and the sealing rubber platform B constitute a complete locking seal, and the pipe joint, the locking seal and the metal flange are fastened and pressed together; one end of the signal line core is connected to a banana plug for plugging the induction probe after passing through the locking seal through the pipe joint, and the signal line shielding layer is fastened to the pipe joint by a fixing bolt; the banana plug is located in the metal flange hole, and the connecting end of the banana plug and the signal line core is embedded in the bottom of the sealing rubber platform B.

[0009] A further improvement of the utility model is that the induction probe is insulated from the metal flange through an insulating fixing sleeve.

[0010] A further improvement of the utility model is that a metal pressure pad is provided at the connection end between the banana plug and the core of the signal line.

[0011] A further improvement of the present invention is that both the sealing glue platform A and the sealing glue platform B are of cone-shaped structure.

[0012] A further improvement of the utility model is that the pipe joint, the locking seal and the metal flange are connected as one by fastening and pressing through connecting bolts.

[0013] A further improvement of the utility model is that a slot is provided on the bottom side of the sealant stage B, and the connecting end of the banana plug and the signal line core is installed in the slot.

Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0021] Please refer to the attached Figure 1-3 , combined with a specific embodiment, it is described as follows: The utility model describes a waterproof quick-connect device for connecting a signal line and a sensing probe, comprising a metal flange 3, a pipe joint 7, a signal line core 8 and a signal line shielding layer, the pipe joint 7 is connected to the metal flange 3, and a locking rubber pad 6 is arranged between the pipe joint 7 and the metal flange 3.

[0022] The top side of the locking rubber pad 6 is provided with a sealing rubber platform A601 which can be installed in the hole of the pipe joint 7, and the bottom side of the locking rubber pad 6 is provided with a sealing rubber platform B602 which can be installed in the hole of the metal flange 3. The locking rubber pad 6, the sealing rubber platform A601 and the sealing rubber platform B602 are provided with threading holes.

[0023] The locking rubber pad 6, the sealing rubber base A601 and the sealing rubber base B602 form a complete locking seal, and the pipe joint 7, the locking seal and the metal flange 3 are fastened and pressed together by the connecting bolts 10 to form a detachable structure.

[0024] One end of the signal line core 8 passes through the locking seal through the pipe joint 7 and is connected to a banana plug 4 for plugging the sensing probe 1. The signal line shielding layer is fastened to the pipe joint 7 by a fixing bolt 9. The banana plug 4 is located in the hole of the metal flange 3, and the connection end of the banana plug 4 and the signal line core 8 is embedded in the bottom of the sealant platform B602.

[0025] Specifically, the sensing probe 1 is insulated from the metal flange 3 by the insulating fixing sleeve 2 .

[0026] The working principle of the utility model: after the pipe joint 7, the locking seal and the metal flange 3 are tightened and pressed, the banana plug 4 can be plugged into the induction probe 1. Since the sealing glue station B602 wraps the connection end of the banana plug 4 and the signal line core 8 at its bottom, the wiring insulation is ensured, and the banana plug 4 and the metal flange 3 and the pipe joint 7 are also well insulated through the locking rubber pad 6. At the same time, by squeezing the hole wall of the metal flange 3 and the pipe joint 7, the threading hole can be used for locking, thereby ensuring the waterproofness of the wiring. In addition, the signal line shielding layer is fixed on the pipe joint 7, thereby realizing the reliable grounding of the signal line shielding layer.

[0027] In one embodiment, a metal pressure pad 5 is provided at the connection end between the banana plug 4 and the signal line core 8. By using the metal pressure pad 5, the banana plug 4 can be pressed into the induction probe 1 better.
