Spot-welded is carried out with the anode or cathode of the salient point and battery；However in the prior art, the salient point of setting is all
It is arc-shaped shape setting, the area of battery and bump contacts is too small after welding, and use for a long time in this way is easy to produce fever
The phenomenon that.And in subsequent detection process, because the junction between salient point and battery is too small, in the detection process, inspection
The case where survey personnel are difficult to find salient point and whether battery is not in rosin joint, desoldering, the welding that not can guarantee battery pack is qualified
Rate.Therefore, it is necessary to be improved further existing connection terminal to solve the above problems.
Utility model content
In view of this, the utility model is in view of the existing deficiencies of the prior art, main purpose is to provide a kind of electronic work
The battery plus-negative plate connection terminal of tool is improved by the weld part welded together to the anode or cathode with battery,
The phenomenon that previous use for a long time is easy to produce fever can not only be efficiently solved, and is also possible that testing staff more holds
The case where easily whether there is rosin joint, desoldering between detection weld part and the anode and cathode of battery.
To achieve the above object, the utility model is using following technical solution:
A kind of battery plus-negative plate connection terminal of electric tool, the connection terminal include main part, lead division and weldering
Socket part, the main part, lead division and weld part are integrally formed flaky textures；The weld part is equipped with salient point, this is convex
The top surface of point is equipped in the top surface of the salient point in planar structure setting and multiple eats tin hole.
As a preferred embodiment: the tin hole of eating is the multiple circular through holes for being uniformly threaded through salient point top surface.
As a preferred embodiment: the weld part is that upward bending is formed in the side of main part.
As a preferred embodiment: the weld part is equipped with isolation channel, which is divided into the first sheet body for welding portion
With the second sheet body.
As a preferred embodiment: the salient point be respectively spacing be arranged in it is multiple on the first sheet body and the second sheet body.
As a preferred embodiment: the end two sides of the lead division set to the concave fluted to form a plug division.
As a preferred embodiment: being equipped with location hole on the main part and lead division.
The utility model has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technology
Known to scheme: by the way that the top surface of salient point to be arranged in planar structure, salient point being enabled to connect with the positive or negative pole of battery
Contact area it is bigger；It can not only guarantee the reliability of its conducting electric current when long-time uses in this way, but also can
To prevent between salient point and battery because long-time uses the case where generating heat；In addition worn on salient point it is multiple eat tin hole, one
It is more secured that aspect can be improved the welding between weld part and anode or cathode, on the other hand can allow testing staff can
Easily to observe the case where whether there is rosin joint, desoldering between salient point and battery in the bottom of salient point.
For the structure feature and effect for more clearly illustrating the utility model, come with reference to the accompanying drawing with specific embodiment pair
The utility model is described in detail.

Specific embodiment
It please refers to shown in Fig. 1 to Fig. 2, it to be a kind of that show the specific structures of the preferred embodiment of the utility model
The battery plus-negative plate connection terminal of electric tool, the connection terminal include main part 10, lead division 20 and weld part 30.
Wherein, the main part 10, lead division 20 and weld part 30 are integrally formed flaky texture, the weld part
30 be that upward bending is formed in the side of main part 10.The end two sides of the lead division 20 set to the concave fluted 21 with shape
At a plug division 22, it can be directly plugged into the circuit board of electric tool using the plug division 22 and connection is connected, without progress
Connection is connected with conducting wire in welding.Location hole 11 is equipped on the main part 10 and lead division 20.
In the present embodiment, the weld part 30 is equipped with salient point 31, and the top surface of the salient point 31 is arranged in planar structure,
The top surface of salient point 31 is arranged in planar structure, the contact area for enabling to salient point 31 to connect with anode or cathode
It is bigger；It can not only guarantee the reliability of its conducting electric current when long-time uses in this way, but also salient point can be prevented
Because long-time uses the case where generating heat between 31 and anode or cathode.
The weld part 30 is equipped with isolation channel 32, which is separated into the first sheet body 301 and second for weld part 30
Sheet body 302；By being separated the first sheet body 301 and the second sheet body 302, compared in the past only with the connection of a sheet body
For terminal, the drop between weld part 30 and battery can reduce, can further reduce weld part 30 and anode
Or cathode welding when there are rosin joints, desoldering the case where.
The salient point 31 be respectively spacing be arranged on the first sheet body 301 and the second sheet body 302 it is multiple；The salient point 31
Top surface be equipped with it is multiple eat tin hole 311, tin hole 311 is eaten by setting, in salient point 31 and when welding battery, tin liquor can
It is flowed into and eats in tin hole 311 and flowed out to bottom；On the one hand the welding that can be improved between weld part 30 and battery is more firm
Gu on the other hand can allow testing staff can be easily in the bottom of salient point 31 observation salient point 31 and anode or cathode
Between whether there is rosin joint, desoldering the case where；If tin liquor then will not be to eating tin hole 311 because of the case where there are rosin joints, desoldering
Bottom outflow.
It says in more detail, the salient point 31 is rounded planar structure, and the tin hole 311 of eating is uniformly to be threaded through
Multiple circular through holes of 31 top surface of salient point；The planar structure of certain salient point 31 can also be rectangular planar or ellipse
Circular planar, similarly, which can also carry out the transformation of various shapes according to actual needs.
The above descriptions are merely preferred embodiments of the present invention, not makees to the technical scope of the utility model
Any restrictions, therefore any trickle amendment made by the above technical examples according to the technical essence of the present invention, equivalent change
