Description
Technical field
The present invention relates to a kind of attachment structure, especially a kind of connector attachment structure of anti-strike-through belongs to solar energy company
Connect the technical field of device.
Background technology
Solar DC connector is mainly used in photovoltaic combiner box, terminal box, and the photovoltaic apparatus such as inverter, electric energy is defeated
Go out to use just have associated components as transport vehicle, photovoltaic system with DC connector be between confluxing, the equipment such as inversion
Or play transmission electric current, the interface unit of safeguard protection between load device.Solar energy connector needs outer protection shell
Destruction of the external material such as dust and aqueous vapor to solar energy connector is prevented, when specifically used, the company of solar energy connector is constituted
Joint needs to be assemblied on seal box, while, it is necessary in seal box encapsulating.In seal box during encapsulating, in seal box
Connection cephalic par there is gap, glue can be entered in connector by glue.And after glue enters in connector, can be even
Solidified in joint, cause connector can not dismantle or use, influence the normal use or replacing of connector.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art to connect knot there is provided a kind of connector of anti-strike-through
Structure, its compact conformation can be prevented effectively from glue and enter in connector, it is ensured that the normal use or replacing of connector.
The technical scheme provided according to the present invention, the connector attachment structure of the anti-strike-through, including seal box and peace
Loaded on the connector on the seal box；The connector includes connection plastic housing and is installed on inserting in the connection plastic housing
Pin, contact pin is located in seal box；It is used to seal contact pin with being connected plastic housing joint portion with being connected the joint portion of plastic housing and being provided with contact pin
The sealing-plug in gap, the sealing-plug is located in seal box.
The sealing-plug is inserted in along contact pin in the end of connection plastic housing, and sealing-plug is tapered, and sealing-plug is installed on connection modeling
After in shell, the external diameter of sealing-plug is tapered into along the direction that contact pin points to connection plastic housing.
The contact pin is with being connected plastic housing in coaxial distribution, and the end of connection plastic housing is stretched into seal box, and stretches into seal box
Interior connection plastic housing is fastenedly connected by locking nut with seal box.
Advantages of the present invention：The joint portion gap between contact pin and connection plastic housing is sealed using sealing-plug, so that in sealing
In box during encapsulating, glue can not be again introduced into by joint portion gap in connection plastic housing, so as to ensure that the normal of connector is used
Or change, compact conformation is safe and reliable.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is the structural representation of sealing-plug of the present invention.
Description of reference numerals：1- seal boxes, the connectors of 2- first, the connectors of 3- second, the locking nuts of 4- first, 5- second
Locking nut, 6- sealing-plugs, the contact pins of 7- first and the contact pins of 8- second.
Embodiment
With reference to specific drawings and examples, the invention will be further described.
As depicted in figs. 1 and 2：Enter in order to be able to be prevented effectively from glue in connector, it is to avoid the normal of influence connector makes
With or change, the present invention includes seal box 1 and the connector that is installed on the seal box 1；The connector includes connection
Plastic housing and the contact pin being installed in the connection plastic housing, contact pin are located in seal box 1；In contact pin and the joint portion for being connected plastic housing
Provided with the sealing-plug 6 for sealing contact pin with being connected plastic housing joint portion gap, the sealing-plug 6 is located in seal box 1.
Specifically, seal box 1 is square or rectangular-shaped, and one or more connectors are installed on seal box 1, when there is multiple companies
During joint, connector is located at the same side or same one end of seal box 1, and the contact pin of connector is located in seal box 1, connection plastic housing
Main body is located at outside seal box 1.Gap of the contact pin with being connected plastic housing joint portion is sealed by sealing-plug 6, so that when in seal box 1
During encapsulating, glue can not by contact pin be connected plastic housing joint portion gap enter connector connection plastic housing in, so as to
The usage amount of glue is reduced, also avoids energy glue from entering connection plastic housing and influence the normal use or replacing of connector.
Further, the sealing-plug 6 is inserted in along contact pin in the end of connection plastic housing, and sealing-plug 6 is tapered, sealing-plug 6
After being installed in connection plastic housing, the external diameter of sealing-plug 6 is tapered into along the direction that contact pin points to connection plastic housing.
In the embodiment of the present invention, there is the sealing-plug mounting hole of insertion sealing-plug in sealing-plug 6, pass through sealing-plug mounting hole
It can be enclosed on contact pin, and be retracted into along the length direction of contact pin in connection plastic housing, to realize between sealing contact pin and connection plastic housing
Joint portion gap.During 6 tapered structure of sealing-plug, the installation of sealing-plug 6 can be conveniently realized.The contact pin is with being connected plastic housing in same
Axle be distributed, connection plastic housing end stretch into seal box 1, and the connection plastic housing stretched into seal box 1 by locking nut with it is close
Jacket 1 is fastenedly connected.
In Fig. 1, two connectors, respectively the first connector 2 and the second connector 3 are mounted with seal box 1, the
One connector 2 includes the first connection plastic housing and the first contact pin 7 being installed in the first connection plastic housing, the second connector 3
Including the second connection plastic housing and the second contact pin 8 being installed in the second connection plastic housing, the connection of the first connector the 2, the 3rd
First 3 be in parallel distribution, and the joint portion between the first contact pin 7 and the first connection plastic housing is sealed by sealing-plug 6 in the first connector 2
Gap, the joint portion gap between the second contact pin 8 and the second connection plastic housing is sealed in the second connector 3 by sealing-plug 6.First
Connector 2 is fastenedly connected by the first locking nut 4 and seal box 1, and the second connector 3 passes through the second locking nut 5 and sealing
Box 1 is fastenedly connected；When needing to change the first connector 2 or the second connector 3, it is only necessary to unclamp the first locking nut 4 or the
Two locking nuts 5.
The present invention seals the joint portion gap between contact pin and connection plastic housing using sealing-plug 6, so as to be filled in seal box 1
During glue, glue can not be again introduced into by joint portion gap in connection plastic housing, so that ensure the normal use or replacing of connector,
Compact conformation, it is safe and reliable.
