Abstract
The utility model discloses a middle joint with enhanced water resistance. The middle joint comprises a middle joint body and is characterized in that insulating sleeves protruding out of two ends of the middle joint body are arranged at two ends of the middle joint body, are communicated with the inner part of the middle joint body and are made of elastic material. According to the middle joint with the enhanced water resistance, the mounting is convenient, the operations of installation workers are simple, and the operation requirement is low; and the electrical structure of an original product is not changed, and the original electrical performance is not lowered.
Description
Technical field
The utility model relates to a kind of electric cable fitting, particularly a kind of transition joint.
Background technology
Transition joint is a kind of accessory that installing cables usually uses, and field of employment commonly used is buried or worker's well.Because these local physical features are lower, often can be flooded in rainy season or than wet weather, therefore, the requirement of waterproof measure is very high, otherwise can cause serious consequence.At present; the structure of normally used transition joint body as shown in Figure 1; it is comprised of external protection, shielded-plate tube, stress cone and insulating barrier; its waterproof is to process like this: after the shielded-plate tube place that two cables that need to connect are inserted into transition joint inside fixes, respectively the two ends of cable body and transition joint are tightly wrapped to realize water-tight with water blocking tape.Because transition joint itself has certain thickness; therefore external protection and the cable body of transition joint have certain vertical range; water blocking tape must twine multilayer could realize preferably water-tight, and this operates in narrow and small operating space the workman is very large test.And water blocking tape or waterproof gasket cement etc. are aging or fit bad with cable body and cause water to enter the transition joint body interior, and the accident that causes transition joint to puncture happens occasionally.Therefore, necessity is improved existing transition joint structure.
The utility model content
The purpose of this utility model is to provide a kind of transition joint that strengthens water resistance, and this transition joint is easy to use, and water resistance is good.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of transition joint that strengthens water resistance, comprise the transition joint body, and it is characterized in that, be provided with the insulating sleeve at outstanding two ends at the two ends of transition joint body, insulating sleeve is connected with the transition joint body interior.
Preferred version is that described insulating sleeve refers to the insulating sleeve that elastomeric material is made.The elastic pressure that elastomeric material forms is conducive to the applying between waterproof material and the cable body, more is conducive to waterproof effect.
Described insulating sleeve refers to the insulating sleeve that adopts rubber to make.
The external diameter of described insulating sleeve is less than the external diameter of transition joint body.Such scheme not only is conducive to save material, and insulating sleeve is not too thick also is conducive to the operation of digging.
Described transition joint refers to the ferrule sleeve that is comprised of external protection, shielded-plate tube, stress cone and insulating barrier; Described insulating sleeve is positioned at the two ends of transition joint body and is connected with insulating barrier.Be conducive to like this fixing of insulating sleeve and strengthen intensity.
Preferred version is that described insulating sleeve and insulating barrier are one-body molded.Be conducive to like this processing and manufacturing.
The transition joint of enhancing water resistance of the present utility model is to use like this: during installation, the insulating sleeve that to give prominence to two ends is first dug, two cables that needs are connected are after the transition joint body is in place, junction at cable and transition joint body two ends coats the waterproof sealing clay, then turn down insulating sleeve, cover on the lute in.The caoutchouc elasticity enclasping force press seal clay of insulating sleeve is close to cable body, thereby reaches the effect of water blockoff.In order to add strong pressure, can also tighten with band (or larynx hoop) in the insulation rubber tube outside.
The utility model possesses following outstanding advantages and effect with respect to prior art:
1, the transition joint of enhancing water resistance of the present utility model is easy for installation, and the installer's is simple to operate, and requiring of operation is low;
2, the transition joint of enhancing water resistance of the present utility model is reasonable in design ingenious, takes full advantage of the caoutchouc elasticity enclasping force and strengthens water plugging effect;
3, the transition joint of enhancing water resistance of the present utility model increases outstanding insulating sleeve at the transition joint two ends, does not change original product electrical structure, does not reduce original electric property.
Description of drawings
Fig. 1 is the structural representation of the present transition joint body that uses;
Fig. 2 is the structural representation of the transition joint of enhancing water resistance of the present utility model;
Wherein, 1 is that stress cone, 2 is that shielded-plate tube, 3 is that insulating barrier, 4 is that external protection, 5 is insulating sleeve.
Embodiment
Below in conjunction with embodiment the utility model is described in further detail, but execution mode of the present utility model is not limited to this.
Embodiment one
The structure of the transition joint of enhancing water resistance of the present utility model as shown in Figure 2; be comprised of transition joint body and insulating sleeve 5: the transition joint body is comprised of external protection 4, shielded-plate tube 2, stress cone 1 and insulating barrier 3, and insulating sleeve 5 is positioned at the two ends of transition joint body and is connected with insulating barrier 3.The insulating sleeve that insulating sleeve 5 adopts rubber to make.The external diameter of insulating sleeve 5 is less than the external diameter of transition joint body.
The transition joint of enhancing water resistance of the present utility model is to use like this: the insulating sleeve 5 that will give prominence to first transition joint body two ends is dug, two cables that needs are connected are after the transition joint body is in place, junction at cable and transition joint body two ends coats the waterproof sealing clay, then turn down insulating sleeve 5, cover on the lute in.The caoutchouc elasticity enclasping force press seal clay of insulating sleeve is close to cable body, thereby reaches the effect of water blockoff.In order to add strong pressure, can also tighten with band (or larynx hoop) in the insulation rubber tube outside.
Embodiment two
The present embodiment and embodiment one difference only be, insulating sleeve 5 is one-body molded with insulating barrier 3.
Embodiment three
The present embodiment and embodiment one difference only be, insulating sleeve 5 adopts other insulation elastomeric materials of nonrubbers to make.
Above-described embodiment is the better execution mode of the utility model; but execution mode of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection range of the present utility model.
