For OT terminal.OT terminal is also referred to as round cold end terminal, can be easily achieved chain type bridge joint, closely adjacent in terminating wire position
When, it can improve insulation safety degree and prevent conducting wire bifurcated, be widely used on the market.
During making OT terminal, need to carry out closure sealing to one end of OT terminal its cylindrical tail portion.Current
Technique generally first carries out pre-determined bit closure using silica gel, then realizes firm closure to silica gel position injection molding epoxy resin again,
Finally the silica gel to help out is taken out again.But such a set of process flow is more complicated, expends working hour；And it infuses
It is inconsistent so as to cause the hole depth of OT terminal it is easy to appear the thickness of injection molding is inconsistent when moulding epoxy resin；Third, using note
The mode of modeling epoxy resin is also difficult to ensure the consistent of OT terminal leakproofness.
Utility model content
The purpose of the utility model is to provide a kind of OT terminal, solve in the prior art by the way of being molded epoxy resin
The technics comparing for blocking OT terminal is complicated, it is difficult to the problem of guaranteeing hole depth consistency and sealing consistency.
To solve the above problems, the utility model provides a kind of OT terminal, the OT terminal includes disc-shaped head, tail portion
And lid of blocking up.Tail portion has channel in cylindrical shape and inside, and disc-shaped head is integrally engaged in one end of tail portion.
Lid of blocking up is plugged in channel made of punching press and by way of interference fit, and lid of blocking up is located at tail portion and disc-shaped head
One end of engagement.
According to an embodiment of the present invention, lid of blocking up is plugged in channel by way of welding or riveting.
According to an embodiment of the present invention, lid of blocking up is metal cover.
According to an embodiment of the present invention, disc-shaped head and the tail portion are all made of tin plating nickel, copper, copper nickel plating, cold
Roll one of carbon steel material.
According to an embodiment of the present invention, tail portion includes inner ring body and outer ring body, and inner ring body uses epoxy resin material
And the filling inside in outer ring body, one end and disc-shaped head of outer ring body integrally engage.
Another aspect according to the present utility model, the utility model further provide for OT terminal described in any of the above embodiments and exist
Application on temperature sensor, wherein one end of the temperature-sensitive wire rod of the temperature sensor is equipped with thermistor, temperature-sensitive wire rod
One end is inserted into and is packaged in the channel of tail portion, and thermistor contacts lid of blocking up.
Compared with prior art, the technical program has the advantage that
The utility model is blocked by the way of being blocked up lid made of the punching press by interference fit in the logical of OT terminal tail portion
In road, realizes and block OT terminal.Lid of blocking up in the fabrication process individually batch stamped, blocking up for stamping out can cover it
Size especially thickness is more accurate than more consistent, in this way after lid of blocking up blocks in the channel of tail portion, it is ensured that institute
State the consistency of the hole depth of OT terminal and the consistency of sealing.Second, lid of blocking up directly is blocked by the way of interference fit
In the channel of tail portion, eliminates and assisted in traditional technology by silica gel and need to remove the numerous of silica gel again after completion of the injection-moulding
General labourer's sequence, it is simple and quick.

Specific embodiment
It is described below and is served only for disclosing the utility model so that those skilled in the art can implement the utility model.With
Embodiment in lower description is only used as illustrating, it may occur to persons skilled in the art that other obvious deformations.It is retouched following
The basic principle of the utility model defined in stating can be applied to other embodiments, deformation scheme, improvement project, equivalent program
And other are without departing from other schemes of the spirit and scope of the utility model.
As shown in Figure 1, the utility model provides a kind of OT terminal, also referred to as round cold end terminal.The OT terminal includes circle
Sheet head 10, tail portion 20 and lid 30 of blocking up.
Disc-shaped head 10 is used for wiring, and disc-shaped head 10 is using nickel, copper is tin plating, copper nickel plating, one in cold-rolled carbon steel
Kind material.For example, disc-shaped head 10 can use SPCC material, wherein SPCC indicate generally with cold rolling carbon steel sheet and
Steel band, chemical component and mechanical performance are equivalent to Chinese trade mark Q195 and Q215A.
Tail portion 20 has channel 201 in cylindrical shape and inside.Disc-shaped head 10 is integrally engaged in tail portion 20
One end.Similarly, tail portion 20 uses one of tin plating nickel, copper, copper nickel plating, cold-rolled carbon steel material.For example, tail portion 20 can be with
Using SPCC material.
Further, tail portion 20 includes inner ring body 21 and outer ring body 22, and the use epoxy resin material of inner ring body 21 is simultaneously filling
In the inside of outer ring body 22, that is to say, that inner ring body 21 be first it is filling inside outer ring body 22 by the epoxy resin of liquid, so
Solid epoxy resin is formed using hot setting afterwards, to be engaged in inside outer ring body 22.One end of outer ring body 22 and circle
Sheet head 10 integrally engages.
