Fig. 2 is the partial structural diagram of the electrical connection module of one embodiment of the application.It please refers to shown in Fig. 2, the electricity
Connection component 20 includes first terminal 21 and Second terminal 22.The first terminal 21 and Second terminal 22 are conducting element,
Selective connection (electrical connection) is realized by engagement and disconnection between the two.The manufacture material of any one in the two can with it is existing
The manufacture material of Bonding Pad is identical, such as can also use a variety of conductive golds using single metals such as copper, iron, titaniums
Belong to the alloy formed according to predetermined ratio.In addition, any one in the two can be single layer structure, or multilayer conductive metal
It is sequentially overlapped the composite layer to be formed.
The first terminal 21 includes the first noumenon 211 and is recessed inwardly setting from the side of the first noumenon 211
Groove 212.The Second terminal 22 includes that the second ontology 221 and extending outwardly from the side of second ontology 221 is set
The protrusion 222 set.
Referring to Fig. 2, described raised 222 are sticked in groove 212, the first terminal 21 and Second terminal are realized with this
Electrical connection between 22, at this point, the first noumenon 211 and the second ontology 221 can be with face contacts.And by described raised 222 from
It is extracted in groove 212, the disconnection being electrically connected between the first terminal 21 and Second terminal 22 can be realized, at this point, described
One ontology 211 and the second ontology 221 completely disengage contact.
It can be seen from the above, being realized between first terminal 21 and Second terminal 22 by means of the engaging of protrusion 222 and groove 212
Electrical connection, without using conducting resinl, in this, when first terminal 21 and Second terminal 22 disconnect electrical connection, without using going
Except the removal liquid of conducting resinl, removal liquid damage first terminal 21 and Second terminal 22 can be avoided.In addition, raised 222 He
This implementation itself having conducive to heavy industry operation that is connected together of groove 212, can promote heavy industry operation and realize 21 He of first terminal
Yield when being electrically connected between Second terminal 22.
Please continue to refer to Fig. 2, the groove 212 can be the blind hole being opened on the first noumenon 211, in order to ensure
The structural strength of first terminal 21 and the above-mentioned fastness being connected together, the depth of the groove 212 can be the first noumenon 211
The half of thickness.
In addition, the shape of the groove 212 and protrusion 222 can exactly match, when protrusion 222 and the engaging of groove 212,
Maximum face contact is realized between the two.
Further, the groove 212 can be using the small but internal big design that is open, i.e., the maximum of the described groove 212
Radial dimension is greater than the radial dimension of the groove 212 opening, and specifically, the first terminal 21 is set in the opening of groove 212
It is equipped with blocking portion 213, the blocking portion 213 is extended towards the center that groove 212 is open.By Second terminal 22 towards
When one terminal 21 pushes, deformation occurs due to the extruding of protrusion 222 for the blocking portion 213, is equivalent to the opening hair of the groove 212
Raw deformation, after protrusion 222 enters groove 212, which restores deformation, and is placed in protrusion 222 and the second ontology
Between 221, in this, the blocking portion 213 is abutted against with the protrusion 222 being inserted in groove 212, stops the protrusion with this
222 exit from groove 212, to be conducive to improve the stability of electrical connection.
In this application, the quantity for the groove 212 that each first terminal 21 is included can be set according to actual needs
It sets, however it is not limited to one shown in Fig. 2, such as can also be three shown in Fig. 3, accordingly, institute in each Second terminal 22
State protrusion 222 quantity it is identical with the quantity of the groove 212 on each first terminal 21 and correspond engage.
In addition, the application does not limit the opening shape of the groove 212 yet, for example, refering to Fig. 3, along perpendicular to first end
The direction of visual lines of son 21, the shape that the groove 212 is open can be rectangle, and certainly, the opening of the groove 212 may be
Round or other polygons.
Incorporated by reference to shown in Fig. 4, the electrical connection module 20 can also include the first sealing 23 and the second sealing 24.First
