Description
Technical field
The present invention relates to a kind of interference electric connecting sheet.
Background technology
In the application in high-energy or high-power field, all seldom use single monomer as the ultracapacitor and the battery of energy-storage travelling wave tube.Along with the progress of science and technology, personalized electronic product increases day by day, for the scope of application of these energy storage products of bigger lifting, generally all is assembled into module and uses.In the assembling process of module, brace is a key factor, it not only is related to the size of contact resistance, and the assembling process of brace influences the performance of module to a great extent, the assembly environment temperature of brace has certain requirement, but but this ambient temperature has very big influence to the performance of module, and machining accuracy and the assembly tool to connecting hole also has higher requirement simultaneously, and assembled condition is relatively harsher.
Be illustrated in figure 1 as traditional electric connecting sheet structure, respectively there is a connecting hole 2 on the corresponding both sides that connect energy storage monomer pole place on brace body 1, are used for brace is enclosed within pole.The connection of existing mode energy storage monomer is divided into the gap connection and is connected two kinds with interference.The gap ease of connection realizes, connects defective unreliable, that easily get loose but exist.Adopt the interference connected mode, connect reliably, compact dimensions has obtained using widely in environment that vibration is arranged and locking demanding field.The faying face that interference is connected to adopts interference fit, generally can only utilize the principle of expanding with heat and contracting with cold of metal, assembles by the mode of hot charging or cold charge.In connection procedure, cause the monomer performance to change because the too high or temperature drop of temperature rise is crossed conference, and change and have uncertainty; Secondly, need accurately control the precision of connecting hole when adopting such hot charging or cold charge mode to connect, increase difficulty of processing; The 3rd, need respectively the energy storage monomer before the installation and brace is lowered the temperature respectively or the intensification preliminary treatment, influenced production efficiency, increased installation cost; In addition, if it is bad that effect is installed, loose contact or other problems appear between brace and the energy storage monomer, may this situation be not easy when mounted to find, but in the energy-storage module use during heavy-current discharge, both might be because brace and the bad serious problems that occur of contacting of energy storage monomer, the situation that energy-storage module maybe can occur burning.
Therefore, adopting the performance of module of the electric connecting sheet assembling of present structure is that the accurate control of forward each link guarantees that the carelessness of any one operation will influence the stability of whole energy-storage module.
Summary of the invention
The purpose of this invention is to provide a kind of interference electric connecting sheet, with solve existing brace interference in connecting the problems such as instability that caused of the hot charging that must adopt or cold charge connected mode.
For achieving the above object, the present invention adopts following technical scheme: a kind of interference electric connecting sheet, comprise two connecting holes that are used for pushing up with the perforation brace of the corresponding suit of energy storage monomer pole the bottom surface that brace body and both ends thereof are provided with respectively, described connection hole offers a breaking joint that runs through hole wall and hole outside end face and bottom surface, perforation brace top.
Described two connection holes offer at least one from the straight joint of hole wall to the bottom surface, perforation brace top of the body extension of inboard, hole.
Electric connecting sheet of the present invention is provided with breaking joint in the connection hole makes the connecting hole can elastic dilatation at the seam place, does not need monomer and brace are carried out preliminary treatment, has saved the time, has improved production efficiency, has reduced cost; Simultaneously breaking joint the requirement on machining accuracy that can reduce connecting hole is set, can carry out the adaptivity adjustment between connecting hole and the pole, improved crimping dynamics and applying degree between them; In addition, can be connected on the monomer by simple frock or equipment, realize that the normal temperature between each monomer connects, the harmful effect of having avoided traditional connected mode that monomer and module performance are caused, can combine more closely by the contact-making surface friction between each monomer, thereby reduce contact resistance.
Being provided with of straight joint can make installation more simple and convenient, realizes better effects if.

Embodiment
Be specific embodiments of the invention below, but the application that does not limit the present invention in any way.
As shown in Figures 2 and 3 for the structural representation of interference electric connecting sheet specific embodiment of the present invention, comprise the connecting hole 2 that is used for pushing up the bottom surface that brace body 1 and both ends thereof are provided with respectively with the perforation brace of the corresponding suit of energy storage monomer pole, two connection holes offer a breaking joint 3 that runs through hole wall and hole outside end face and bottom surface, perforation brace top, the straight joint of present embodiment extends to the side of brace body, and connect the connecting hole side, form the single radial cut brace.Breaking joint 3 shown in Figure 2 is positioned on the extended line at two connecting hole centers, and this structure is the structure of relatively optimizing; 3 of breaking joints shown in Figure 3 are positioned at any place of this brace ring bodies outside.
Be depicted as the structural representation of second kind of embodiment of electric connecting sheet of the present invention as Fig. 4～6, be with Fig. 2～3 differences, the brace of present embodiment runs through hole wall and hole outside end face and connects the breaking joint 3 of bottom surface, brace top except that being provided with one, also be provided with a non-perforation straight joint 4 towards the body center position, form two opening braces at it.Breaking joint 3 shown in Figure 4 and straight joint 4 all are positioned on the extended line at two connecting hole centers, and brace assembles the expansionary force maximum that can bear when stressed, and is not yielding, so the actual effect effect of this structure is ideal; Straight joint 4 shown in Figure 5 is on the extended line at two connecting hole centers, and the position of breaking joint 3 does not overlap with the extended line of straight joint 4; Straight joint 4 shown in Figure 6 and breaking joint 3 be not all on the extended line at two connecting hole centers.
