A kind of relay connection sheet comprising the contact portion for being electrically connected with external equipment, the solidus portion for being electrically connected with relay coil enameled wire and the mounting portion fixed for connection sheet installation；The solidus portion includes substrate, the first lug for winding for enameled wire and the second lug for compressing enameled wire the end of a thread, the substrate is connect with contact portion and mounting portion respectively, the first lug and the second lug are located at the side of substrate, and the first lug is equipped with the limiting section for preventing coiling to be detached from.When assembling relay, the end of a thread of coil can be wrapped in the first lug to pre-bend by worker, and the end of a thread of coil is placed on the second lug position；Last bending first lug compresses coiling, and the second lug of bending compresses the end of a thread, so can not only be electrically connected coil and connection sheet, and the connection reliability of the two is larger, the end of a thread not readily disengages from connection sheet.
Description
Technical field
The utility model relates to relay, especially a kind of relay connection sheet.
Background technique
Existing relay includes that plastic cap and plastic cap cooperatively form the shell of accommodating cavity, are located in accommodating cavity body
Bobbin, be wrapped in bobbin coil, the iron core being located in bobbin, the first spring covered on iron core, by first
The first copper sheet that bolt is fixed on plastic cap, the second copper sheet being fixed on plastic cap by the second bolt and it is located at the first bronze medal
Contact between piece and the second copper sheet.The connection sheet of relay is fixed on bobbin, and the end of a thread of coil is welded by welding procedure
It connects in connection sheet, to form the electric connection of coil and connection sheet and the fixation of coil the end of a thread.The connection type of enameled wire
Wire bonding process are increased, increase the production cost of relay, and solder joint is easy to fall off, the stability of connection is poor.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of relay connection sheets, reduce being produced into for relay
This, provides the reliability that coil is connect with connection sheet.
In order to solve the above technical problems, the technical solution of the utility model is: a kind of relay connection sheet comprising be used for
The contact portion that is electrically connected with external equipment, the solidus portion for being electrically connected with relay coil enameled wire and for connection sheet
Fixed mounting portion is installed；The solidus portion includes substrate, the first lug for winding for enameled wire and for compressing enamel-cover
Second lug of line the end of a thread, the substrate are connect with contact portion and mounting portion respectively, and the first lug and the second lug are located at
The side of substrate, the first lug are equipped with the limiting section for preventing coiling to be detached from.When assembling relay, worker can be by coil
The end of a thread be wrapped in the first lug to pre-bend, the end of a thread of coil is placed on the second lug position；Last bending first lug
Coiling is compressed, the second lug of bending compresses the end of a thread, so coil and connection sheet can be not only electrically connected,
And the connection reliability of the two is larger, and the end of a thread not readily disengages from connection sheet.
As an improvement, the mounting portion is bent to form by the root of connection sheet in 90 °.
As an improvement, the limiting section includes positioned at the first protrusion of first lug side and positioned at the first lug other side
The second protrusion, the first protrusion forms First Transition face with first lug side, and the second protrusion forms the with the second lug side
Two transition faces.
As an improvement, First Transition face is staggered with the second transition face.
As an improvement, the spacing between the first lug and the second lug is 0.7 ~ 1.0mm.
Brought beneficial effect is the utility model compared with prior art:
Enameled wire is wrapped in first lug, forms the electric connection of coil and connection sheet, saves bonding wire craft；Utilize first
Lug bending compresses coiling, is compressed the end of a thread using the second lug, increases the reliability of the two connection；First lug side limit
The design in position portion can further prevent coiling to be detached from.
Detailed description of the invention
Fig. 1 is the schematic diagram of connection sheet and bobbin cooperation.
Fig. 2 is connection sheet schematic diagram.
Fig. 3 is enlarged drawing at the A of Fig. 2.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings of the specification.
As shown in Figure 1, 2, a kind of relay connection sheet, is mounted on bobbin 2, and connects with the coil 3 on bobbin 2
It connects.Connection sheet 1 includes contact portion 11 for being electrically connected with external equipment, be used for and relay coil enameled wire is electrically connected
Solidus portion 12 and fixed mounting portion 13 is installed for connection sheet 1；Contact portion 11, solidus portion 12 and mounting portion 13 are by copper sheet one
Body punch forming.As shown in figure 3, the solidus portion 12 includes substrate 125,121 and of first lug for winding for enameled wire
For compressing second lug 122 of enameled wire the end of a thread；The substrate 125 is connect with contact portion 11 and mounting portion 13 respectively, substrate
Mounting groove is formed between 125 side and the side of contact portion 11, the first lug 121 and the second lug 122 are located at substrate
125 side and it is located in mounting groove, spacing between the first lug 121 and the second lug 122 is 0.7 ~ 1.0mm, is made
It is with enough winding spaces；The first lug 121 is equipped with the limiting section for preventing coiling to be detached from, and the limiting section includes
Positioned at the first protrusion 123 of 121 side of first lug and the second protrusion 124 positioned at 121 other side of first lug, the first protrusion
123 form First Transition face with 121 side of first lug, and the second protrusion 124 and 122 side of the second lug form the second transition
Face, First Transition face are staggered with the second transition face；The design of 121 side limiting section of first lug can further prevent coiling de-
From.The mounting portion 13 is bent to form by the root of connection sheet in 90 °, and when installation, mounting portion 13 is inserted into the jack of bobbin
It is interior.
When assembling relay, the end of a thread of coil can be wrapped in the first lug 121 to pre-bend by worker, the line of coil
Head is placed on 122 position of the second lug；Last bending first lug 121 compresses coiling, bends the second lug 122 for the end of a thread pressure
Tightly, so coil and connection sheet can be not only electrically connected, and the connection reliability of the two is larger, the end of a thread is not
It is easily separated from connection sheet.
