In charging operation, cable need to require fasten, the prior art, which is unable to satisfy, to be wanted by biggish electric current to fitting contact surface
It asks.It is loosened at cable connection, short circuit easily occurs, causes safety problem.2, at high cost: as shown in Fig. 2, existing cable connector
Whole non-dismountable, maintenance cost is higher, and entire power grid establishes the higher cost needed.3, it has a single function: disposable connection,
Once accident occur needs replacement comprehensively.4, mechanical strength is low: as shown in Fig. 1, number of terminals used in cable connection is 1
Only, mechanical strength is inadequate.5, terminal is without plating, and for a long time using oxidizable, service life is short.6, flood control humidity resistance compared with
Difference can not adapt to wet environment.
Summary of the invention
In order to solve the problems, such as cable connecting terminal in the prior art, the present invention provides a kind of highly-safe, mechanical strength
35kV prefabricated cable transition joint high, of good performance.
Realize the technical solution of the object of the invention are as follows:
A kind of 35kV prefabricated cable transition joint, including shell, interior of shell from outside to inside successively include external shielding layer,
The crimp type terminal of insulating layer, inner conducting layer and connecting cable, it is characterised in that: the shell both ends are equipped with integral type stress cone,
The shell is equipped with the insulating plug for being communicated to shell inner conducting layer；The end that the crimp type terminal can be linked together by two
Son composition is first terminal and Second terminal；The first terminal and Second terminal are separately connected two sections of cables.
The first terminal and Second terminal are bolted.
Described kind of 35kV prefabricated cable transition joint shell and two sections of cables are fixed by fixed frame.
The first terminal and Second terminal and two sections of cables are in the same horizontal position.
The first terminal and the interconnecting piece of Second terminal all have 45° angle, and interconnecting piece mutual cooperation makes two ends of crimping
Son is in the same horizontal position with two sections of cables.
The stress cone and shell are integral type or split type.
The first terminal and Second terminal surface are equipped with electroplated layer.
The invention has the benefit that
The present invention integrally can be dismantled and be repaired, and it can be used repeatedly for the accessories such as crimp type terminal and bolt, reduce maintenance
Cost.
The present invention is using hermetically sealed, therefore waterproof, humidity resistance are preferable, can adapt to different construction environments.
The interconnecting piece of first terminal and Second terminal in the present invention all has 45° angle, and interconnecting piece mutual cooperation makes to crimp
Two terminals and two sections of cables are in the same horizontal position, are then connected and sealed with insulating plug shell and terminal, greatly
The set-up time is shortened, and quick and easy for installation.

Specific embodiment
Fig. 1-Fig. 8 is to explain the present invention, but the present invention is not limited in Fig. 1-range shown in Fig. 8.
As depicted in figs. 1 and 2, cable intermediate joint in the prior art,
A kind of 35kV prefabricated cable transition joint, including shell, interior of shell successively include external shielding layer from outside to inside
1, the crimp type terminal 4 of insulating layer 2, inner conducting layer 3 and connecting cable, it is characterised in that: answered equipped with integral type at the shell both ends
Power cone, the shell are equipped with the insulating plug 5 for being communicated to shell inner conducting layer；The crimp type terminal can be connected to one by two
The terminal composition risen, is first terminal and Second terminal；The first terminal and Second terminal are separately connected two sections of cables 6.
The present invention is connected first terminal with Second terminal by bolt 7, and passes through the fixed transition joint and two of fixed frame 8
The cable at end not only ensure that bonding strength but also can determine and correct the direction of cable.
First terminal and Second terminal and two sections of cables are in the same horizontal position.
Preferably, first terminal and the interconnecting piece of Second terminal all have 45° angle, and interconnecting piece mutual cooperation makes crimping two
Terminal and two sections of cables are in the same horizontal position, are then connected and sealed with insulating plug shell and terminal, greatly shorten
Set-up time, and it is quick and easy for installation.
