Description

A kind of comb-type ground connection copper lug

Technical field

The connector that the utility model is related to a kind of to connect with electrical equipment for cable, and in particular to a kind of comb-type connects Ground copper lug.

Background technology

In electric substation, in order to meet the consistent requirement of whole station reference voltage, need to realize whole station voltage one point earth. The method for realizing one point earth before exactly sets in master control room mother short to all protections, measurement, metered voltage progress N on observing and controlling cabinet Ground connection.To meet the requirement of national security regulation, need to use 16mm²Ground wire, since the jack in terminal block can only It is inserted into 4mm²Line, so the method for traditional handicraft is 16mm²Ground wire end insulated hull peel off, copper wire is divided into 4 Wisp is inserted into terminal block, and cable trailer is then carried out crimping ground connection using copper lug.Conventional method there are the drawbacks of： （1）Ground wire insulated hull peels off a point bundle type and is attached in terminal block moulding unsightly.（2）Ground wire is inserted into terminal block in a point bundle When fracture there may be copper wire or copper wire be bent the case where, cause copper wire not reach with terminal block real contact area and want The 16mm asked².（3）Cable insulation wrapper peel off average mark bundle the technological level of installation personnel is required it is high, and Production Time at This is higher.

Patent Office of the People's Republic of China is open on 03 22nd, 2017（It accuses）A CN206041008U patents, entitled one kind Terminal block, the utility model propose a kind of terminal block, including ontology, are provided on the side wall of ontology for being pacified with electrical box Fixed mounting portion is filled, parallel arranged is provided with partition in the ontology, and lug plate, the wiring are provided between adjacent partition Piece is flat shim, and the mounting portion is embedded in the side wall of the ontology.When the sectional area of ground wire is excessive, also need by Ground wire is divided into multiply and goes to connect with the terminal block.

Utility model content

The purpose of the utility model is to overcome above-mentioned deficiencies existing in the prior art, and provide a kind of structure design conjunction The comb-type of reason is grounded copper lug, solves the problems, such as that the jack use space in terminal block is limited, and manufacturing cost is low, uses It is convenient, it improves work efficiency, while handsome in appearance.

The technical scheme in the invention for solving the above technical problem is：A kind of comb-type ground connection copper lug, including with Further include the insert row for being caught in terminal block, the line storehouse is connect with insert row, is had on the insert row in the line storehouse of connection ground wire Latch.The line storehouse is common copper lug line storehouse, on insert row the size length of latch through design can close and firm be caught in terminal On row, so that, thicker ground wire is not connect with terminal block again without being divided into several stocks, can directly be connect with line storehouse, Latch is caught in terminal block again.

Further, the insert row is parallel with the axial direction in line storehouse.

Further, the insert row has multiple latches, latch to be generally aligned in the same plane.

Further, there are four latches for the insert row.

Further, the line storehouse is closed line storehouse, and line storehouse is hollow cylindrical.

Further, the line storehouse is the aperture lines storehouse of arc.

Further, the insert row fixes the intermediate position in online storehouse.

Further, the latch is vertically fixed on the end of insert row far from the position in line storehouse, the tangent line of latch and line storehouse It is parallel.

Further, the length of the latch is less than the length of insert row.

The utility model compared with prior art, has the following advantages and effect：

（1）The voltage circuit ground connection operation of ground wire becomes simple；

（2）It eliminates conventional method and there may be the ground connection substandard requirement of cross-sectional area；

（3）Manufacturing cost is low, handsome in appearance.

Fig. 2 is the overlooking structure diagram of the utility model embodiment.

Fig. 3 is the side structure schematic view of the utility model embodiment.

In figure：Line storehouse 1, insert row 2, latch 3.

Specific implementation mode

The utility model is described in further detail below in conjunction with the accompanying drawings and by embodiment, and following embodiment is pair The explanation of the utility model and the utility model is not limited to following embodiment.

Embodiment.

Referring to Fig. 1 to Fig. 3, a kind of comb-type ground connection copper lug includes for connecting the line storehouse 1 being grounded and for being caught in The insert row 2 of terminal block, line storehouse 1 are fixedly connected with integrated molding with insert row 2.

Line storehouse 1 is the aperture lines storehouse of arc, and insert row 2 is located at the intermediate position in line storehouse 1, and insert row 2 and the axial direction in line storehouse 1 are flat Row.

There are latch 3, latch 3 to be vertically fixed on the end of insert row 2 far from the position in line storehouse 1, latch there are four being set on insert row 2 3 is parallel with the tangent line in line storehouse 1, and the width of latch 3 is of same size with insert row 2, there is the line of rabbet joint between latch 3 and latch 3, the line of rabbet joint Width is of same size with latch 3, and latch 3 is in the same plane；The length of latch 3 is less than the length of insert row 2, and latch 3 Size length through design can close and firm be caught in corresponding terminal block.

16mm²Ground wire connect with line storehouse 1, the latch on insert row 2 is caught in terminal block.

Furthermore, it is necessary to illustrate, the specific embodiment described in this specification, the shape of parts and components is named Claiming etc. can be different, described in this specification above content is only to the utility model structure example explanation. The equivalence changes or simple change that all structure, feature and principles according to described in the utility model patent concept are done, are wrapped It includes in the protection domain of the utility model patent.Those skilled in the art of the present invention can be to described Specific embodiment does various modifications or additions or substitutes by a similar method, without departing from the knot of the utility model Structure or beyond the scope defined by this claim, all should belong to the protection range of the utility model.
