     This application is a Continuation Application of application Ser. No. 16/838,247 filed in United States on Apr. 2, 2020, which is a Division of Application of application Ser. No. 15/708,627, which is a Continuation Application of application Ser. No. 14/149,239. The prior applications are herewith incorporated by reference in its entirety. 
    
    
     BACKGROUND 
     Technical Field 
     The disclosure relates to a battery module, and particularly to a continuable power module in which the number of the batteries thereof can be increased or reduced according to user&#39;s requirements. 
     Related Art 
     Due to the invention of batteries, the power of electric appliances is no longer dependent on the supply mains, such that the electric appliances can be operated in different occasions and environments, thereby significantly increasing the usefulness of the electric appliances. 
     However, even batteries with the same voltage may be of different sizes and/or shapes, so that the user finds it difficult to choose the proper battery for their device. For instance, for two electric razors operating at 6 volts, the batteries used might be different due to the difference between the brands or the receiving spaces for the batteries. 
     In addition, the voltage requirements for different electric appliances may not be the same, and the voltage provided by a single battery is fixed, such that several batteries are connected to each other in a head-to-tail manner firstly to meet the operation voltage of the electric appliance, and then the connected batteries are connected electrically to the electric appliance. In view of this, since there is no structure for fastening one battery with another, a battery receiving groove with enough structural strength is essential for the electric appliance, so that the batteries received and positioned within the electric appliance can be connected electrically to each other and drive the electric appliance. 
     Additionally, the batteries are separated from outer circumstances via the battery receiving groove, such that water or dust will not make influence to the electrical connections of the batteries; conversely, when the batteries are not received in the battery receiving groove, there is no any waterproof or dustproof design for the electrical connections of the batteries.

     DETAILED DESCRIPTION 
     Hereinafter, for convenience, the term “electric device” is substantially the same as the term “electronic device”; and the term “electric appliance” is substantially the same as the term “electronic appliance”.

The continuable power module  100  includes at least one battery  20  capable of being received in a battery receiving groove of an electric appliance so as to offer electricity for the electric appliance. Additionally, the operating voltages for different electric appliances would not be the same, so that the number of the batteries  20  for operating the electric appliances is adjustable case by case. Hereinafter, for ease of reading and recognition, battery  20  is the generic term of battery  20   a  and battery  20   b ; that is, although some figures and some paragraphs only mention about battery  20   a , it is also applicable for battery  20   b  and battery  20 . 
     Please refer to  FIG.  1   ,  FIG.  2    and  FIG.  4   , in which the battery  20  includes a main body  21 , a first electrode terminal  221  (i.e., a first terminal member), a second electrode terminal  231  (i.e., a second terminal member), and a conducting terminal  232 . In this embodiment, the main body  21  is approximately formed as a round cylinder, but embodiments of the disclosure are not limited thereto; the structure of the main body  21  can also be a cuboid, a triangular cylinder and so forth for correspondingly receiving in the battery receiving groove. That is, the outer diameter of the battery  20  is approximately equal to the inner diameter of the battery receiving groove. Additionally, although the heights of the batteries  20  shown in the features are the same, but embodiments of the disclosure are not limited thereto; that is, the heights of the batteries  20  can be different for correspondingly receiving the battery cores  201  with different voltages, or can be the same for receiving the battery cores  201  with different voltages. Here, the battery core  201  can be the battery core of a dry cell, an alkaline cell or a lithium cell, but embodiments of the disclosure are not limited thereto; for instance, the battery core  201  can also be the battery core of a rechargeable cell. Here, the number of the battery cores  201  is not limited in the main body  21  of each battery  20 . Additionally, in some embodiments, the battery core  201  is connected electrically to the aforementioned terminals via conducting wires or circuit boards with the aiding of welding, packaging and connecting means so forth, instead of directly connected electrically to the aforementioned terminals. 
     The main body  21  has a connecting end  22  (i.e., a male terminal body) and a continuing end  23  (i.e., a female terminal body) respectively defined at two ends thereof. The first electrode terminal  221  is disposed at the connecting end  22 , and the second electrode terminal  231  is disposed at the continuing end  23 . The structure of the second electrode terminal  231  matches with the structure of the first electrode terminal  221 , such that the first electrode terminal  221  of the battery  20   b  is connected electrically to the second electrode terminal  231  of the battery  20   a . The first electrode terminal  221  and the second electrode terminal  231  are respectively connected electrically to the battery core  201 ; that is, one end of the first electrode terminal  221  of the battery  20   b  which is exposed out of the main body  21  can be connected to one end of the second electrode terminal  231  of the battery  20   a  which is exposed out of the main body  21 , while the other end of the first electrode terminal  221  of the battery  20   b  and the other end of the second electrode terminal  231  of the battery  20   a  are respectively connected to the corresponding battery cores  201  of the battery  20   a  and the battery  20   b . Here, the first electrode terminal  221  can be the positive terminal, and the second electrode terminal  231  can be the negative terminal, but embodiments of the disclosure are not limited thereto; that is, the electric potential of the first electrode terminal  221  is different from that of the second electrode terminal  231 . As shown in  FIG.  4   , the first electrode terminal  221  is connected electrically to the positive terminal of the battery core  201 , and the second electrode terminal  231  is connected to the negative terminal of the battery core  201 . For convenience, hereinafter, the first electrode terminal  221  is defined as the positive terminal and the second electrode terminal  231  is defined as the negative terminal. 
     The conducting terminal  232  includes a secured end  2321  (i.e., a secured terminal member) and a free end  2322  (i.e., a free terminal member); namely, two ends of the conducting terminal  232  are respectively the secured end  2321  and the free end  2322 . The secured end  2321  is disposed at the continuing end  23 , while the free end  2322  is detachably connected to the first electrode terminal  221 . For each battery  20   a ,  20   b , the conducting terminal  232  is connected electrically to the first electrode terminal  221  via the free end  2322 , such that the continuing end  23  of one battery  20   a  is connected to the connecting end  22  of another battery  20   b  to form a series connection for increasing the outputted voltage. In this embodiment, the first electrode terminal  221 , the second electrode terminal  231 , and the conducting terminal  232  are secured in the main body  21  via plastic injection molding techniques; that is, when the aforementioned terminals are manufactured and the corresponding relationships therebetween are built, the main body  21  of the battery  20  can be produced by plastic injection molding with the aforementioned terminals being embedded in the main body  21 ; but embodiments of the disclosure are not limited thereto, those who are skilled in the art might apply other techniques to dispose the aforementioned terminal in the main body  21 . Additionally, being embedded in the main body  21 , the aforementioned terminals can also be disposed in the space defined in the main body  21 , as shown in  FIG.  3 D . 
     Please refer to  FIG.  3 A , in which in one implementation aspect, the connecting end  22  includes a positioning portion  22   a , and a positioning structure  22   b . The positioning portion  22   a  is recessed at a center of the connecting end  22  for receiving the first electrode terminal  221  and the free end  2322  of the conducting terminal  232 , while the positioning structure  22   b  is annularly disposed at an inner wall of the positioning portion  22   a . Here, the positioning structure  22   b  is an internal threading structure, but embodiments of the disclosure are not limited thereto; in some cases, the positioning structure  22   b  can be an engaging groove or structures similar thereto. As shown in  FIG.  3 A , in one embodiment, an exposed length L of the first electrode terminal  221  is approximately equal to the height H of the wall surface of the continuing end  22  having the positioning structure  22   b  (i.e., the height of the male terminal body). 
     The continuing end  23  includes a limiting portion  23   a , a void  23   b , and a limiting structure  23   c . The continuing end  23  further includes an extension portion  34 ′ and a tunnel  23   d . The extension portion  34 ′ is protruding from a middle portion of the continuing end  23 , and the tunnel  23   d  is recessed from a middle portion of the extension portion  34 ′ for receiving the second electrode terminal  231  and the secured end  2321 . The limiting portion  23   a  is protruded from a center of the continuing end  23 , and the structure thereof is matched with the structure of the positioning portion  22   a  of the connecting end  22 . The void  23   b  is located at a center of the limiting portion  23   a  for receiving the second electrode terminal  231  and the secured end  2321  of the conducting terminal  232 . That is, the void  23   b  is for receiving the extension portion  34 ′ along with the second electrode terminal  231  and the secured end  2321 . Hence, a surrounding groove (i.e., an outer portion of the void  23   b ) is formed between an inner wall of the limiting portion  23   a  and an outer wall of the extension portion  34 ′. The limiting structure  23   c  is annularly disposed at an outer wall of the limiting portion  23   a  for correspondingly matching with the positioning structure  22   b  of the connecting end  22 . Here, the limiting structure  23   c  is an external threading structure so as to threading with the positioning structure  22   b , but embodiments of the disclosure are not limited thereto; in some cases, the limiting structure  23   c  can be an engaging block or other structures so as to be detachably connected to the positioning structure  22   b . As shown in  FIG.  3 A  to  FIG.  3 D , in one embodiment, an end portion of the extension portion  34 ′ is substantially flushed with an end portion of the secured end  2321  (i.e., the secured terminal member), the second electrode terminal  231  (i.e., the second terminal member) is separated from the secured end  2321  by the extension portion  34 ′, an end portion of the second electrode terminal  231  is not flushed with the end portion of the extension portion  34 ′, the second electrode terminal  231  is enclosed by the extension portion  34 ′, and one end of the tunnel  23   d  is closed. As shown in  FIG.  3 C , in one embodiment, one end of the void  23   b  is closed. 
     Via the matching between the positioning portion  22   a  and the limiting portion  23   a  and the matching between the positioning structure  22   b  and the limiting structure  23   c , the continuing end  23  of the battery  20   a  is connected and fastened with the connecting end  22  of the battery  20   b , and the free end  2322  is received in the surrounding groove. 
     Please refer to  FIG.  3 B , in which in one implementation aspect, the connecting end  22  includes a limiting portion  22   a ′, a void  22   b ′, and a limiting structure  22   c ′. The limiting portion  22   a ′ is protruded from a center of the connecting end  22 . The void  22   b ′ is located at a center of the limiting portion  22   a ′ for receiving the first electrode terminal  221  and the free end  2322  of the conducting terminal  232 . The limiting structure  22   c ′ is annularly disposed at an outer wall of the limiting portion  22   a ′. Here, the limiting structure  22   c ′ is an external threading structure, but embodiments of the disclosure are not limited thereto; the limiting structure  22   c ′ can also be an engaging block. The continuing end  23  includes a positioning portion  23   a ′ and a positioning structure  23   b ′. The continuing end  23  further includes an extension portion  34 ′ and a tunnel  23   d ′. The extension portion  34 ′ is protruding from a middle portion of the continuing end  23 , and the tunnel  23   d ′ is recessed from a middle portion of the extension portion  34 ′ for receiving the second electrode terminal  231  and the secured end  2321 . The positioning portion  23   a ′ is recessed at a center of the continuing end  23  for receiving the second electrode terminal  231  and the secured end  2321  of the conducting terminal  232  and correspondingly matches with the limiting portion  22   a ′ of the connecting end  22 . That is, the positioning portion  23   a ′ is for receiving the extension portion  34 ′ along with the second electrode terminal  231  and the secured end  2321 . Hence, a peripheral groove  23   c ′ is formed between an inner wall of the positioning portion  23   b ′ and an outer wall of the extension portion  34 ′. The positioning structure  23   b ′ is annularly disposed at an inner wall of the positioning portion  23   a ′ so as to correspondingly match with the limiting structure  22   b ′ of the connecting end  22 . Here, the positioning structure  23   b ′ is an internal threading structure, but embodiments of the disclosure are not limited thereto; the positioning structure  23   b ′ can also be an engaging groove so as to correspondingly match with the engaging block. Similarly, via the matching between the positioning portion  23   a ′ and the limiting portion  22   a ′ and the matching between the positioning structure  23   b ′ and the limiting structure  22   c ′, the continuing end  23  of the battery  20   a  is connected and fastened with the connecting end  22  of the battery  20   b , and the free end  2322  is received in the peripheral groove  23   c ′ (not shown). As shown in  FIG.  3 B , in one embodiment, an exposed length L of the first electrode terminal  221  is less than the height H of the wall surface of the continuing end  22  having the limiting structure  22   c ′ (i.e., the height of the male terminal body). 
     Please refer to  FIG.  4    again, in which in this embodiment, the first electrode terminal  221  is a thin rod-like structure, and the second electrode terminal  231  is a circular groove structure which has a receiving space (that is the space defined in the second electrode terminal  231 ) for correspondingly receiving the first electrode terminal  221 . The secured end  2321  of the conducting terminal  232  is a ring structure disposed around the outer periphery of the second electrode terminal  231 . In other words, the second electrode terminal  231  and the secured end  2321  of the conducting terminal  232  are disposed concentrically. The conducting terminal  232  is made of conductive material, such as metal, conductive rubber, conductive polymer, etc. The free end  2322  of the conducting terminal  232  is a flexible stripe structure, so that the free end  2322  of the conducting terminal  232  is movably leant against the first electrode terminal  221 . As shown in  FIG.  3 A , the free end  2322  is detachably in contact with a middle portion of the first electrode terminal  221 . As shown in  FIG.  3 A , the free end  2322  has an inclined portion  2322   b  and a bent portion  2322   a  connected to the inclined portion  2322   b , the bent portion  2322   a  is detachably in contact with an outer wall of the first electrode terminal  221  in a point-contact manner. As shown in  FIG.  3 A , the bent portion  2322   a  is a V-shaped structure, and a bottom portion of the V-shaped structure is detachably in contact with the outer wall of the first electrode terminal  221  in the point-contact manner. As shown in  FIG.  3 A , in one embodiment, the bottom portion of the V-shaped structure has a curved surface. As shown in  FIG.  3 A , in one embodiment, the inclined portion  2322   b  is connected to a tail portion  2322   c  of the bent portion  2322   a , and an obtuse angle is between the tail portion  2322   c  and the inclined portion  2322   b . Here, the number of the conducting terminal  232  is two, and the two free ends  2322  of the two conducting terminals  232  are respectively leant against the two sides of the first electrode terminal  221 ; but, it is understood that the number of the conducting terminal  232  is not limited thereto. 
     Please refer to  FIG.  3 A , in which when the battery  20   a  is not connected to another battery  20   b , the free end  2322  of the conducting terminal  232  is leant against the first electrode terminal  221 , such that the conducting terminal  232  is connected electrically to the first electrode terminal  221  via the free end  2322 . Therefore, the positive terminal and the negative terminal of the battery  20   a  are respectively defined at the secured end  2321  of the conducting terminal  232  and the second electrode terminal  231 . Please refer to  FIG.  4   , in which when the continuing end  23  of the battery  20   a  is connected to the connecting end  22  of the battery  20   b , the free end  2322  of the conducting terminal  232  of the battery  20   b  is detached from the first electrode terminal  221  and leant against an outer periphery of the secured end  2321  of the conducting terminal  232  of the battery  20   a , such that the second electrode terminal  231  of the battery  20   a  is connected electrically to the first electrode terminal  221  of the battery  20   b . Under this arrangement, the positive terminal and the negative terminal are respectively at the secured end  2321  of the conducting terminal  232  and the second electrode terminal  231  of the battery  20   b . Similarly, when the battery  20   a  is detached from the battery  20   b , the free end  2322  of the conducting terminal  232  of the battery  20   b  is again leant against the first electrode terminal  231  thereof, such that the conducting terminal  232  thereof is connected electrically to the first electrode terminal  231  via the free end  2322 . 
     Based on the above, when the batteries  20   a  is connected to the battery  20   b  via a series connection, the continuing end  23  of the battery  20   a  is connected to the connecting end  22  of the battery  20   b ; meanwhile, the second electrode terminal  231  of the battery  20   a  is correspondingly connected to the first electrode terminal  221  of the battery  20   b . Under this arrangement, a number of batteries  20  are connected electrically to each other via a series connection, so that the voltages of the continuable power module  100  are increased.

The second embodiment is generally similar to the first embodiment, except that the continuable power module  300  of the second embodiment further has a base member  10  connectable with the battery  20 . In this embodiment, the structure of the base member  10  matches with the structure of the battery  20  so as to be round cylindered, but embodiments of the disclosure are not limited thereto; the structure of the base member  10  can also be a cuboid, a triangular cylinder and so forth for correspondingly receiving in the battery receiving groove; that is, the outer diameter of the base member  10  is approximately equal to the inner diameter of the battery receiving groove.

The linking end  12  is disposed at one side of the base body  11 . The first contacting terminal  121  is disposed at the linking end  12 , and the structure of the first contacting terminal  121  is substantially the same as that of the second electrode terminal  231  and matches with the structure of the first electrode terminal  221  of the battery  20 , such that the first contacting terminal  121  of the base member  10  is connected electrically to the first electrode terminal  221  of the battery  20 . The second contacting terminal  122  is disposed at the linking end  12  of the base body  10  and connected electrically to the first contacting terminal  121 . Here, the structure of the linking end  12  is substantially the same as the structure of the continuing end  23  of the battery  20 ; in other words, the structure of the linking end  12  of the base member  10  is corresponding to the structure of the connecting end  22  of the battery  20 . Similarly, the structures of the first contacting terminal  121  and the second contacting terminal  122  are generally similar to the structures of the second electrode terminal  231  and the secured end  2321  of the conducting terminal  232  respectively; certainly, when the linking end  12  of the base member  10  is connected electrically to the connecting end  22  of the battery  20 , the first contacting terminal  121  and the second contacting terminal  122  of the linking end  12  are respectively matched with the first electrode terminal  221  and the free end  2322  of the conducting terminal  232  of the battery  20 , the detail connection mechanism between the battery  20  and the base member  10  is substantially similar to that between a number of batteries  20  so as to be omitted here. 
     Please refer to  FIG.  5 B , in which in one implementation aspect, the base member  10 ′ includes a base body  13  and a receiving end  14 . The receiving end  14  is disposed at one side of the base body  13 , and the structure thereof matches with the connecting end  22  of the battery  20  so as to receive the first electrode terminal  221  and the free end  2322  of the conducting terminal  232  of the battery  20 . Here, the receiving end  14  has a containing groove (that is, the space defined inside the receiving end  14 ), to receive the first electrode terminal  221  and the free end  2322  of the conducting terminal  232 . Under this arrangement, when the battery  20  is connected to the base member  10 , the positioning portion  22   a  of the battery  20  is enclosed by the base member  10 , such that the free end  2322  of the conducting terminal  232  received in the positioning portion  22   a  is not detached from the first electrode terminal  221  via the outside affections, the electrical connection between the first electrode terminal  221  and the free end  2322  of the conducting terminal  232  being maintained within the receiving end  14 . 
     Please refer to  FIG.  5 A  again, in which in one implementation aspect, the base member  10  has a fixing portion  10   a  disposed at a periphery of the base body  11 , so that the base member  10  can be fastened with the battery receiving groove of the electric appliance. In this embodiment, the fixing portion  10   a  is a locking-connecting structure which has threaded patterns so as to be fastened with the battery receiving groove, but embodiments of the disclosure are not limited thereto. In one embodiment, the base member  10  is formed as a cone structure, and the diameter is gradually decreased from the bottom thereof toward the linking end thereof with an elastic rubber ring fitted thereover (not shown), so that the base member  10  is capable of closely attaching with the battery receiving groove via the elasticity of the elastic rubber ring; additionally, the elastic rubber ring also provides a function of waterproofing which avoids liquids or dusts from entering into the battery receiving groove and influencing the operation of the electric appliance. 
     In one implementation aspect, a first waterproof member  10   b  made of elastic material is adjacently disposed to the fixing portion  10   a  of the base member  10  and around the periphery of the base member  10  so as to be capable of proving a function of waterproofing; for example, the first waterproof member  10   b  can be a rubber washer, but embodiments of the disclosure are not limited thereto. 
     Please refer to  FIG.  5 A  again, in which commonly, the diameter (the cross-sectional area), of one end of the base body  11  which is opposite to the linking end  12  thereof is larger than that of the linking end  12 , such that when the fixing portion  10   a  has correspondingly been fastened with the battery receiving groove of the electric appliance, parts of the base member  10  are still exposed out of the battery receiving groove and the battery  20  can be exchanged conveniently. In this embodiment, the base member  10  is an adapting member and does not have the function of providing electricity (namely, the base member  10  does not have the battery core  201 ), but embodiments of the disclosure are not limited thereto; in some embodiments, the base member  10  has the battery core  201  disposed therein (as shown in  FIG.  6   ), and the battery core  201  is connected electrically to the first contacting terminal  121  and the second contacting terminal  122  and capable of providing electricity as the battery  20  does. 
     Furthermore, please refer to  FIG.  2   ,  FIG.  3 A ,  FIG.  4    and  FIG.  6   , in which in order to be capable of waterproofing, following features are introduced into the disclosure. 
     Please refer to  FIG.  4    and  FIG.  6   , in which a second waterproof member  31  is disposed between the battery  20  and the base member  10  and between the battery  20   a  and the battery  20   b . In one implementation aspect, the second waterproof member  31  is fitted over and fastened on the linking end  12  of the base member  10  and the continuing end  23  of the battery  20   a ; while in another implementation aspect, the second waterproof member  31  is disposed at the connecting end  22  of the battery  20   b  (not shown). Based on this, when the battery  20   a  is connected to the battery  20   b  or the base member  10 , moist will not enter into the spaces between the batteries  20   a ,  20   b  or between the battery  20   a  and the base member  10  from the gaps therebetween, such that the leak of electricity is prevented. Here, the second waterproof member  31  is a waterproof washer, and preferably made of rubber, but embodiments of the disclosure are not limited thereto. 
     Please refer to  FIG.  2   ,  FIG.  3 A  and  FIG.  4   , in which the second electrode terminal  231  further has at least one waterproof elastomer  32  assembled in the receiving space thereof. In detail, the waterproof elastomer  32  is fastened in the receiving space of the second electrode terminal  231  and is made of soft material with flexible character, such as foam, silica gel or latex, but embodiments of the disclosure are not limited thereto. Please refer to  FIG.  3 E  and  FIG.  3 F , in which the waterproof elastomer  32  is substantially a hollow cylinder structure made of elastic materials with fluids (liquids or gases), being filled therein. The waterproof elastomer  32  includes an elastomer body  321 , and a channel  322  is opened at a center thereof. The channel  322  has a plurality of protruding portions  323  defined annularly around an inner wall thereof and radially protruded inward along the cross-sectional plane of the middle segment of the waterproof elastomer  32  to block moist from moving from one end of the channel  322  toward the other end of the channel  322 , such that the waterproof elastomer  32  is watertight. Please refer to  FIG.  3 F  again, in which when the first electrode terminal  221  of the battery  20   a  is connected electrically to the second electrode terminal  231  of the battery  20   b , the first electrode terminal  221  is passing through the elastomer body  32  via the channel  322  and connected electrically to the second electrode terminal  231 ; at the same time, the protruding portions  323  of the elastomer body  321  is pressed outwardly toward a direction perpendicular to the inserting direction of the first electrode terminal  221  by the first electrode terminal  221 , so that the elastomer body  321  is closely attached with the receiving space of the second electrode terminal  231  and the moist cannot enter into the receiving space from the gap between the elastomer body  321  and the receiving space. Additionally, as shown in  FIG.  3 F , due to the pressure caused by the first electrode terminal  221  and the circumstances, the middle part of one end of the elastomer body  321  which is exposed outside (that is, one end far from the battery core  201 ), is recessed inward, and the outer periphery thereof is not compressed because of the increasing of the pressure inside the elastomer body  321 . Furthermore, as shown in  FIG.  3 E  and  FIG.  3 F , the second electrode terminal  231  has a terminal inserting portion  2311  and an abutting wall  2312 . The terminal inserting portion  2311  is recessed at the center part of the receiving space of the second electrode terminal  231  and provided for electrically connecting with the first electrode terminal  221 ; while the abutting wall  2312  is substantially the bottom of the receiving space which is capable of blocking and abutting the elastomer body  321  from pressing the terminal inserting portion  2311 . That is, in  FIG.  3 E  and  FIG.  3 F , the terminal inserting portion  2311  is recessed at the center part of the receiving space of the second electrode terminal  231 , but embodiments of the disclosure are not limited thereto, the terminal inserting portion  2311  can be disposed at the bottom of the receiving space or closely attaching with the inner wall of the receiving space. It is understood that, as shown in  FIG.  3 E  and  FIG.  3 F , when the first electrode terminal  221  is connected electrically to the second electrode terminal  231 , the first electrode terminal  221  is attached with the bottom and the inner wall of the terminal inserting portion  2311  of the second electrode terminal  231 , but embodiments of the disclosure are not limited thereto, the first electrode terminal  221  also can be only attached with the bottom or the inner wall of the terminal inserting portion  2311 . As shown in  FIGS.  3 E and  3 F , in one embodiment, a bottom surface of the terminal insertion portion  2311  is a curved surface. Moreover, a space within the receiving space of the abutting portion  2312  is greater than a space within the terminal inserting portion  2311 . 
     As shown in  FIG.  3 A , when the battery  20   a  is not connected to the battery  20   b , the second electrode terminal  231  of the battery  20   a  is substantially protected by the waterproof elastomer  32  so that moist cannot enter into the receiving space of the second electrode terminal  231 . As shown in  FIG.  4   , when the first electrode terminal  221  of the battery  20   b  is connected to the second electrode terminal  231  of the battery  20   a , the waterproof elastomer  32  is extruded and the channel  322  thereof is opened by the first electrode terminal  221 , such that the first electrode terminal  221  is smoothly inserted into the bottom of the receiving space of the second electrode terminal  231  (that is, the first electrode terminal  221  is attached with the terminal inserting portion  2311  of the second electrode terminal  231 ), and the electrical connection between the battery  20   a  and the battery  20   b  is achieved. Similarly, when the first electrode terminal  221  is pulled out from the second electrode terminal  231 , the waterproof elastomer  32  in the receiving space of the second electrode terminal  231  is resiliently moved back to an original position thereof due to the elasticity. 
     Please refer to  FIG.  2   ,  FIG.  3 A  and  FIG.  4   , in which the secured end  2321  of the conducting terminal  232  of the continuing end  23  has a flexible folding member  33  fitted thereover in which the structure thereof is substantially similar to a blast pipe or a shock absorber and capable of being folded and telescoped. As shown in  FIG.  3 A , when the battery  20   a  is not connected to the battery  20   b , the secured end  2321  of the conducting terminal  232  is enclosed by the flexible folding member  33 , thereby preventing the moist from contacting the secured end  2321  of the conducting terminal  232 . Additionally, as shown in  FIG.  4   , when the continuing end  23  of the battery  20   a  is connected to the connecting end  22  of the battery  20   b , the flexible folding member  33  of the battery  20   a  is compressed inward along the length direction of the secured end  2321  of the conducting terminal  232  of the battery  20   a  along with the pushing of the free end  2322  of the conducting terminal  232  of the battery  20   b  and the secured end  2321  of the conducting terminal  232  of the battery  20   a  is exposed out from the flexible folding member  33 , so that the free end  2322  of the conducting terminal  232  of the battery  20   b  is leant against and connected electrically to the secured end  2321  of the conducting terminal  232  of the battery  20   a . Similarly, when the continuing end  23  of the battery  20   a  is detached from the connecting end  22  of the battery  20   b , the flexible folding member  33  of the battery  20   a  is moved resiliently to the original position thereof, due to the elasticity. 
     Briefly, when the battery  20   a  is not connected to the battery  20   b , the waterproof elastomer  32  blocks the moist from entering into the second electrode terminal  231  and prevents from events of leaking electricity; while the flexible folding member  33  has the function of separating the secured end  2321  of the conducting terminal  232  from the circumstance, such that the moist cannot contact the secured end  2321  of the conducting terminal  232 , thereby event of leaking electricity being prevented. When the battery  20   a  is connected to the battery  20   b , the waterproof elastomer  32  of the battery  20   a  is extruded and the channel  322  thereof is opened by the first electrode terminal  221  of the battery  20   b , such that the first electrode terminal  221  of the battery  20   b  is inserted into the second electrode terminal  231  of the battery  20   a  to achieve the electrical connection therebetween; simultaneously, the flexible folding member  33  of the battery  20   a  is compressed inward along the length direction of the secured end  2321  of the conducting terminal  232  of the battery  20   a  along with the pushing of the free end  2322  of the conducting terminal  232  of the battery  20   b  and the secured end  2321  of the conducting terminal  232  of the battery  20   a  is exposed out from the flexible folding member  33 , so that the free end  2322  of the conducting terminal  232  of the battery  20   b  is connected electrically to the secured end  2321  of the conducting terminal  232  of the battery  20   a . Under this arrangement, the battery  20   a  and the battery  20   b  are connected electrically to each other. Conversely, when the battery  20   a  is detached from the battery  20   b , the waterproof elastomer  32  of the battery  20   a  is resiliently moved back to an original position thereof along with the departing of the first electrode terminal  221  of the battery  20   b  due to the elasticity; meanwhile, the flexible folding member  33  of the battery  20   a  is also resiliently moved back to the original position thereof along with the departing of the free end  2322  of the conducting terminal  232  of the battery  20   b.    
     It is understood that the disclosure is not limited with the embodiments having the second waterproof member  31 , the waterproof elastomer  32  and/or the flexible folding member  33 ; in some embodiments, the disclosure does not have the aforementioned waterproof members, as shown in  FIG.  3 C . 
     It is also understood that in order to prevent the second electrode terminal  231  from contacting the secured end  2321  of the conducting terminal  232  (in the case of the base member  10  capable of providing electricity, to prevent the first contacting terminal  121  from contacting the second contacting terminal  122 ), which would lead the short circuit, the extension portion  34 ′ is disposed between the second electrode terminal  231  and the secured end  2321  of the conducting terminal  232  (or between the first contacting terminal  121  and the second contacting terminal  122 ), for separation (in this embodiment, the extension portion  34 ′ may be insulated and called an insulating member  34 ).
