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 this utility model is to overcome the deficiencies in the prior art to be connected 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 utility model, the connector attachment structure of the anti-strike-through, including seal box with
And it is installed on the connector on the seal box；The connector includes connection plastic housing and is installed in the connection plastic housing
Contact pin, contact pin is located in seal box；It is provided with and is combined for sealing contact pin with connection plastic housing in the joint portion of contact pin and connection plastic housing
The sealing-plug in portion 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.
Advantage of the present utility model：The joint portion gap between contact pin and connection plastic housing is sealed using sealing-plug, so that
In seal box during encapsulating, glue can not be again introduced into by joint portion gap in connection plastic housing, so as to ensure the normal of connector
Using or change, compact conformation is safe and reliable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model sealing-plug.
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 utility model is described in further detail.
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 utility model 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 knot for being connected plastic housing
Conjunction portion, which is provided with, is used to seal contact pin with being connected the sealing-plug 6 in plastic housing joint portion gap, and the sealing-plug 6 is 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 utility model embodiment, there is the sealing-plug mounting hole of insertion sealing-plug in sealing-plug 6, pacified by sealing-plug
Dress hole can be enclosed on contact pin, and is retracted into along the length direction of contact pin in connection plastic housing, to realize sealing contact pin with being connected plastic housing
Between 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 coaxial distribution, the end of connection plastic housing is stretched into seal box 1, and the connection plastic housing stretched into seal box 1 passes through locking nut
It is fastenedly connected with seal box 1.
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 utility model seals the joint portion gap between contact pin and connection plastic housing using sealing-plug 6, so that in seal box 1
During interior encapsulating, glue can not be again introduced into by joint portion gap connection plastic housing in so that ensure connector normal use or
Change, compact conformation is safe and reliable.
