Description
Technical field
The present invention relates to a kind of elastic wire folders.
Background technique
Electrical wire clip or connecting terminal are used to form electrical contact or electrical connection, i.e., in an osculating element and an opposite contact
A kind of conductive connection is formed between element.Electrical wire clip using very extensive, need to hold in elevator, electric power, traffic, automation etc.
The field of son connection can all use electrical wire clip.
In the patent of Patent No. DE19817927C1, a kind of electrical wire clip is disclosed, which includes one basic
The terminal spring being in U-shape and a L-shaped metalwork, L shape metalwork have one and the vertically disposed square of conductor direction of insertion
Shape opening, conductor to be connected can be inserted into the opening.U-shaped terminal spring is arranged in said opening with the end of side leg, so that
Before the spring circular arc of terminal spring backward is located at the opening along conductor direction, and one has been inserted by the clamping leg of terminal spring
Conductor be pressed on the edge of the opening, so that terminal spring and metalwork form a spring force clamping connection mechanism.
One disadvantage of above-mentioned patent is: needing to open terminal spring using additional operational instrument can just insert conductors into
To between terminal spring and metalwork, but when operational instrument being utilized to open terminal spring, it may result in the sliding of terminal spring, even make
The end of the side leg of terminal spring is skidded off from the opening, in this way when be inserted into conductor, cannot ensure conductor and metalwork it
Between reliably contact.
In the patent of Patent No. US7083463B2, disclose a kind of electrical wire clip, the electrical wire clip include a terminal spring and
One metalwork, terminal spring have one to clamp leg and a contact leg, and metalwork has a conductive rod piece (conductor bar
Piece), the conductor clamping that the elastic force between leg and conductive rod piece will be inserted is clamped, the contact leg of terminal spring has one to lead to
For being inserted into conducting wire, the one end for simultaneously clamping on leg extends across through-hole in hole.Clamping leg has a maintaining part, the extension side of maintaining part
Parallel to the direction of insertion substantially with conducting wire, parallel with the direction of conductive rod piece simultaneously, conductive rod piece is inserted into along with conducting wire
Through-hole is inserted into contrary direction, so that conductive rod piece is firmly clamped in and is clamped between leg and maintaining part.
In above-mentioned patent, the hardness of terminal spring is higher, when conducting wire is inserted into clamping leg and conductive rod piece, it is also desirable to first use
Other tool open clamp leg, are then again inserted into conducting wire, this makes electrical wire clip inconvenient using existing.Furthermore the terminal end
Moulding process it is more complex.
Summary of the invention
The main purpose of the present invention is to provide a kind of elastic wire folder, single cord or stranded conductor or added with cold end
The thin stranded conductor of head can be inserted directly between terminal spring and metalwork, open electrical wire clip without using additional tool.
It is another object of the present invention to provide a kind of elastic wire folder, the clamping legs of the terminal spring of elastic wire folder
Surface forms a reinforcing rib, and when conducting wire, which is inserted into, to be clamped between leg and metalwork, reinforcing rib can play the role of guiding, to keep away
Exempt to shift when conducting wire insertion；In addition, clamping contact of the leg with conducting wire becomes Multi-contact or line from traditional single-contact
Contact improves the stability of clamping conducting wire；When the conductor size of insertion is identical, be provided with reinforcing rib clamps what leg occurred
Deformation wants small compared with the clamping leg of not reinforcing rib, thus improve terminal spring service life and electrical wire clip it is reliable
Property.
It is another object of the present invention to provide a kind of terminal springs for electrical wire clip, and the shape of the terminal spring is similar to G
Shape, when which is used for electrical wire clip, single cord or stranded conductor or can be direct added with the thin stranded conductor of cold end head
It is inserted between terminal spring and metalwork, without using additional tool to open electrical wire clip.
It is another object of the present invention to provide a kind of terminal spring for electrical wire clip, the clamping leg surfaces of the terminal spring
A reinforcing rib is formed, reinforcing rib can play the role of guiding conducting wire, improve stability when terminal spring clamps conducting wire, and have
Conducive to the service life for improving terminal spring.
To achieve the above objectives, the present invention provides a kind of elastic wire folder, including G shape terminal spring, metalwork and insulation
Shell, the terminal spring and the metalwork are set in the insulation crust, and the insulation crust has wiring inlet, the gold
Belonging to part has a rail-engaging part, and the terminal spring has one to clamp leg, a supporting leg and one keep leg, and the supporting leg is by the folder
Tight leg is connected with the holding leg, and the holding leg is upwardly extended from the side of the supporting leg, and the clamping leg is diagonally downward
Extend to the upper end for keeping leg, the supporting leg has a through-hole, and the rail-engaging part is suitable for from the lower section of the supporting leg
Be inserted into the clampings leg and the holding leg across the through-hole, thus the terminal spring pass through the clamping leg with it is described
The elastic force between leg is kept to be sandwiched in the rail-engaging part.
When conducting wire is inserted into from the wiring inlet, the conducting wire is inserted into the folder under the guidance of the wiring inlet
Between tight leg and the rail-engaging part, so that the elastic force generated using the clamping leg deformation, is tightly clipped in institute for the conducting wire
It states and clamps between leg and the rail-engaging part.For traditional electrical wire clip, the leg that clamps of terminal spring is usually across the logical of supporting leg
Hole is contacted with rail-engaging part, at this moment since the contact point for clamping leg and the rail-engaging part of terminal spring is far from wiring inlet, is led
The length of line insertion end is longer.And in the present invention, the clamping leg of the terminal spring and the contact point of the rail-engaging part are separate
The supporting leg, the contact point is closer to the wiring inlet, therefore the length of the conducting wire insertion end is correspondingly smaller,
To conducting wire insertion when be not susceptible to deformation, so if insertion conducting wire be single cord or be stranded conductor or
When being the thin stranded conductor added with cold end head, it can not be directly inserted into the electrical wire clip by additional tool.
In addition, the terminal spring of G shape is compared with the terminal spring of U-shaped, G shape terminal more convenient with the connection type of metalwork
Spring does not need to connect terminal spring with metalwork by riveting, and only utilizes the clamping leg and the elasticity kept between leg
The terminal spring can reliably be connect by power with the metalwork.In addition, the terminal spring phase of G shape terminal spring and other shapes
