Detailed ways

In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

In the description of the present invention, it should be understood that the terms "upper" and "lower" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

The embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referenced to each other.

It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions. The phrase "includes an element defined by ..." does not exclude the existence of other identical elements in the process, method, article or device including the element".

As shown in Figures 1 to 5, a volumetric formation probe module 100 according to an embodiment of the utility model mainly includes a box body 10, a connecting component 30 and a connecting member 40, wherein an installation space is formed inside the box body 10, and its first panel 11 is used to fix the battery to be tested, and the second panel 12 is used to fix the connecting component 30.

In this embodiment, the installation space in the box 10 is regular as a whole, so in order to avoid knotting, the connector 40 is made of a hard conductor, preferably a copper busbar, which has good conductivity.

When a copper busbar or other hard conductor is used as the connector 40 , a busbar 20 is provided in the box 10 to facilitate the connection, so as to provide a connection relay between the battery to be tested and the connection assembly 30 .

As shown in FIG5 , a plurality of grooves 21 are provided on the busbar 20 , the width of which is the same as the width of the copper busbar, and the depth of which can also be set to be the same as the thickness of the copper busbar, and a third mounting hole 22 is opened in the groove 21 to determine the installation position of the copper busbar to avoid deflection and other inadequate installation situations.

Furthermore, two busbars 20 are provided in the box 10 to increase the number of batteries that can be detected. Of course, when the box 10 is larger and more batteries can be detected, the number of busbars 20 can be further increased.

Since multiple groups of connection components 30 are arranged on the box 10, more copper bars need to be placed in the box 10. Therefore, it should be noted that when using copper bars or other conductors as connectors, they need to be bent and ensure that they do not touch each other to avoid short circuits.

It is easy to imagine that in addition to the copper busbar, aluminum or other conductive materials can also be used, or traditional wires can be used for connection. This embodiment is not limited. Of course, the connection component 30 and the battery to be tested can be directly connected using the connector 40 without using the busbar 20.

In this embodiment, a plurality of connection components 30 are arranged in an array on the second panel 12 in a direction perpendicular to the first panel 11, thereby increasing the number of detectable batteries and improving the detection efficiency. The connection component 30 includes a socket and a plug 32. The socket is fixed on the box 10 and can be quickly plugged with the plug 32, thereby further reducing the operation time and improving the operation efficiency. In addition, under the premise of not causing interference, the gap between adjacent sockets can be minimized to make full use of the space of the box 10 to increase the number of connection components 30, thereby increasing the number of detectable batteries.

Specifically, the socket mainly includes a socket body 311, a sleeve 312 and a terminal 313. The socket body 311 is fixed on the second panel 12, the sleeve 312 is arranged outside the box 10 and has a slot 3121, and the terminal 313 extends between the socket body 311 and the sleeve 312. A mounting hole is arranged at one end of the socket body 311 located in the mounting space of the box 10, and the terminal 313 and the connector 40 are fixed by screws.

Preferably, a first mounting hole 3111 and a second mounting hole 3112 are respectively provided on the upper and lower sides of the socket body 311, and in order to prevent the socket body 311 from being too thick and affecting the number of installations, in the present embodiment, the first mounting hole 3111 and the second mounting hole 3112 are staggered in the length direction of the socket body 311, so that the two are parallel and do not interfere with each other, and at the same time can avoid the short circuit caused in the coaxial case.

Preferably, in order to increase the number of detectable batteries, the number of first mounting holes 3111 and second mounting holes 3112 on a single socket body 311 may be increased to increase the number of detectable batteries of a single connection assembly 30 and the total number of detectable batteries.

Of course, in addition to the screw fixing method, the connecting member 40 can also be fixed to the socket body 311 by welding or other methods, which is not limited in this embodiment.

In this embodiment, the sleeve 312 and the socket body 311 are detachable, and the sleeve 312 does not bear too much support, so buckles 3113 are set on both sides of the panel of the socket body 311, and the sleeve 312 can be fixed to the socket body 311 through the buckles 3113, and can be quickly disassembled and assembled when needed, which improves ease of use. It is understandable that in addition to the detachable fixing method, the sleeve 312 and the socket body 311 can also be integrally formed.

Specifically, the connection assembly 30 is fixed by a screw assembly consisting of a spacer screw 34 and a fixing screw 33. Specifically, as shown in FIGS. 1, 3, and 4, the socket body 311 is first fixed to the box body 10 using the spacer screw 34, and then the plug 32 is fixed to the socket body 311 using the fixing screw 33.

It can be imagined that the length of the isolation column section of the isolation column screw 34 is the same as the distance between the fixed ends of the socket body 311 and the plug 32 when they are in the correct fixed position, avoiding the situation where the fixing effect is poor due to improper insertion or insufficient screwing of the fixing screw 33.

Preferably, an open mounting groove 321 is provided on the plug 32 for fixing the fixing screw 33, which is easier for the staff to operate.

Of course, the plug 32 and the socket may be fixed together without screws and only by plugging, and this embodiment is not limited thereto.

Furthermore, since the cross-sectional shape of the slot 3121 of the sleeve 312 in this embodiment is rectangular, the terminal in the plug 32 is a plate-like structure at least at its plug-in end. Of course, a rigid conductor connector with the same structure as the copper busbar can also be used, and this embodiment is not limited.

It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. The foregoing description of specific exemplary embodiments of the utility model is for the purpose of illustration and illustration. These descriptions are not intended to limit the utility model to the precise form disclosed, and it is obvious that many changes and variations can be made based on the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the utility model and its practical application, so that those skilled in the art can implement and utilize various different exemplary embodiments of the utility model and various different options and changes.
