Detailed Description

In order to make the technical solution of the present application better understood by those skilled in the art, the technical solution of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, shall fall within the scope of the present application.

In the description of the present utility model, it should be understood that the terms "upper," "lower," and the like indicate an orientation or a positional relationship, and are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

In the present specification, each embodiment is described in a progressive manner, and each embodiment focuses on a difference from other embodiments, and the same or similar parts between the embodiments are referred to each other.

It should be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation. The term "comprising" an element defined by the term "comprising" does not exclude the presence of other identical elements in a process, method, article or apparatus that comprises the element.

As shown in fig. 1 to 5, the capacitance probe module 100 according to an embodiment of the present utility model mainly includes a case 10, a connection assembly 30, and a connection member 40, wherein an installation space is formed inside the case 10, a first panel 11 is used for fixing a battery to be tested, and a second panel 12 is used for fixing the connection assembly 30.

In this embodiment, the installation space in the case 10 is regular, so in order to avoid knotting, the connecting member 40 is made of a hard conductor, preferably a copper bar, and has good electrical conductivity.

When copper bars or other rigid conductors are used as the connection members 40, for convenience of connection, a bus bar 20 is provided in the case 10 for providing a connection relay between the battery to be tested and the connection assembly 30.

As shown in fig. 5, a plurality of grooves 21 are provided on the busbar 20, the width of which is the same as the width of the copper bar, the depth of which can be set to be the same as the thickness of the copper bar, and third mounting holes 22 are provided in the grooves 21 for determining the mounting positions of the copper bar, so as to avoid the situation that the copper bar is not mounted in place, such as deflection.

Further, two bus bars 20 are provided in the case 10 for increasing the number of detectable batteries. Of course, when the case 10 is large in volume and there are more detectable batteries, the number of the bus bars 20 may be further increased.

Because the box 10 is provided with the plurality of groups of connecting components 30, more copper bars need to be placed in the box 10, care needs to be taken that bending processing is needed when copper bars or other conductors are used as connecting pieces, contact between the copper bars or other conductors is avoided, and short circuits and other conditions are avoided.

It is easily understood that aluminum or other conductive materials may be used instead of the copper bars, or conventional wires may be used for connection, and the present embodiment is not limited, but the connection member 40 may be used to directly connect the assembly 30 and the battery to be tested without using the bus bar 20.

In the present embodiment, a plurality of sets of connection members 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 assembly 30 comprises a socket and a plug 32, wherein the socket is fixed on the box body 10 and can be quickly plugged with the plug 32, so that the operation time is further reduced, and the operation efficiency is improved. Moreover, on the premise of not causing interference, the gap between adjacent sockets can be reduced as much as possible, and the space of the box body 10 is fully utilized, so that the number of the connecting assemblies 30 is increased, and the number of the detectable batteries is further increased.

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

Preferably, the first mounting hole 3111 and the second mounting hole 3112 are respectively formed on the upper and lower sides of the socket body 311, and in order to avoid the excessive thickness of the socket body 311 affecting the mountable number, in this 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 they are parallel and do not interfere with each other, and at the same time, a short circuit condition generated under the coaxial condition can be avoided.

Preferably, to increase the detectable number of batteries, the number of the first and second mounting holes 3111 and 3112 on the single receptacle body 311 may be increased to increase the detectable number of the single set of connection assemblies 30 and the total number of the detectable batteries.

Of course, the connecting member 40 may be welded or otherwise fixed to the socket body 311, not limited to the screw fixing method.

In this embodiment, the sleeve 312 and the socket body 311 are detachable, and the sleeve 312 does not have excessive supporting function, so that the buckles 3113 are arranged on two 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 assembled and disassembled when needed, so that the usability is improved. It is understood that, in addition to the detachable fixing manner, the sleeve 312 and the socket body 311 may be integrally formed.

In particular to the connection assembly 30, which is fixed using a screw assembly consisting of a spacer screw 34 and a fixing screw 33. Referring specifically to fig. 1, 3 and 4, the socket body 311 is fixed to the case 10 by using the spacer screw 34, and then the plug 32 is fixed to the socket body 311 by using the fixing screw 33.

It is conceivable that the length of the spacer section of the spacer screw 34 is the same as the distance between the fixed ends of the socket body 311 and the plug 32 when the spacer screw is in the correct fixing position, so as to avoid the situation that the fixing effect is poor due to the fact that the socket is not in place or the screwing distance of the fixing screw 33 is insufficient.

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

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

Further, since the cross-sectional shape of the insertion groove 3121 of the sleeve 312 is rectangular in the present embodiment, the terminal in the plug 32 has a plate-like structure at least at the insertion end thereof, and of course, a rigid conductor connector having the same structure as the copper bar may be used, which is not limited in the present embodiment.
