According to an embodiment of the present invention, as shown in fig. 1B and 5B, the tab 165 of the conductive terminal 16 of the outermost other electrical connector module (the rightmost electrical connector module in fig. 1B and 5B) of the electrical connector extends from the bottom wall 116 of the housing 11 of the outermost other electrical connector module. Correspondingly, the electrical connector further comprises an end sealing cap 9, said end sealing cap 9 being adapted to seal a tab 165 extending from the bottom wall 116 of the housing 11 of said outermost further electrical connector module to protect the various components inside the electrical connector from the external environment.
However, in alternative embodiments, such as the embodiment illustrated in fig. 5B, the contact extension 165 of the second electrical connector module 10 on the right side may be omitted, i.e. the right side end face of the second electrical connector module 10 on the right side itself may be closed, in which case no separate end sealing cap 9 need be provided.
According to some embodiments of the present invention, the inner wall of the housing 11 may be provided with a protrusion 122 extending between the fixing arm 146 and the driving arm 144 of the elastic clip 14, as shown in fig. 3B and 4A, to serve to position the fixing arm 146 and the driving arm 144 of the elastic clip 14.
In the embodiment of fig. 3A and 3B, the free end 147 of the fixing arm 146 and the other end 162 of the main body portion 161 of the conductive terminal 16 are both inserted into the through hole 142. And the inner wall of the housing 11 is provided with a notch 124, and the other end 162 of the main body 161 of the conductive terminal 16 is fixed in the notch 124 after passing through the through hole 142.
Further, on the side of the housing 11 opposite to the notch portion 124, there is formed a housing portion 126 for housing the first contact portions 164A, 164B and the second contact portion 165 of the conductive terminal 16, and in the illustrated embodiment, the housing portion 126 penetrates through the housing 11 in the thickness direction thereof.
As further shown in fig. 3A, the accommodating portion 126 includes a partition wall 128, and the one end 163 of the main body portion 161 of the conductive terminal is connected to the first contact portions 164A, 164B and the second contact portion 165 through the partition wall 128.
As further shown in fig. 3B, a guide slot 130 is formed in a side wall of the insertion channel 114 opposite the fixed arm 146 of the spring clip 14 extending generally perpendicular to the side wall to receive the free end of the movable arm 141.
According to some embodiments of the present invention, referring to fig. 2, the driving member 18 has a cylindrical shape, and a U-shaped recess 132 and a boss 134 are formed on a side wall of the housing 11, the boss 134 having a concave arc-shaped top surface.

In the embodiment illustrated in fig. 3A, the driving element 18 is in the form of a button column having a barbell shape, that is, the button column includes a middle thin rod body 181, first contact portions 182 and second contact portions 183 having thick ends, so that the thicker first contact portions 182 facilitate the pressing by the operator, and the thicker second contact portions 183 increase the contact area of the driving element 18 with the elastic clip 14 when the driving element 18 contacts the elastic clip 14, facilitating the pressing operation.
Having described the structure of the individual components of the electrical connector in detail above, the individual use states of the electrical connector according to the embodiments of the present invention are further described below in conjunction with the above description.
Fig. 3A and 3B show a perspective schematic view and a front schematic view, respectively, of the electrical connector module of fig. 2 in a state in which the wires are not inserted, with the cover 12 of fig. 2 removed for clarity of illustration. In a state where the driving member 18 is not pressed, the driving arm 144 pushes the driving member 18 outward (in the left direction in the drawing) due to the elastic force inside the elastic clip 14, and the movable arm 141 blocks the insertion passage 114, resulting in that the through hole 142 of the elastic clip 14 is not aligned with the insertion passage 114 of the housing 11, and at this time, the wire 2 cannot be inserted into the electrical connector module 10 through the insertion passage 114.
Fig. 4A and 4B show a perspective schematic view and a front schematic view, respectively, of the electrical connector module of fig. 2 with the conductors inserted, wherein the cover 12 of fig. 2 is also removed for clarity of illustration. Fig. 4C is an enlarged view of a portion of fig. 4A, in which the insertion of the wire into the through hole to make contact with the conductive terminal is clearly shown.
As shown in fig. 4A to 4C, by pressing the driving member 18 toward the inside of the accommodation space of the housing 11 (i.e., toward the right in the drawing), the driving arm 144 moves the movable arm 141 to the right so that the through hole 142 of the spring clip 14 is aligned with the insertion passage 114 of the housing 11, and at this time, the wire 2 can be inserted into the through hole 142 of the spring clip 14 through the insertion passage 114 of the housing 11. Then, the driving member 18 is released, and the movable arm 141 is moved toward the left side by the elastic force, thereby closing the insertion passage 114, while elastically clamping the wire 2 inserted into the housing 11 on the conductive terminal 16, and maintaining the wire 2 electrically connected to the conductive terminal 16.
Therefore, by utilizing the electric connector module, the electric connector can be formed by modularized assembly, so that electric connection among different numbers of wires is realized, the connection is convenient, the number of parts is reduced, and the manufacturing cost is saved.
Next, a method of electrically connecting a plurality of wires using the above-described electrical connector will be briefly described.

The selected corresponding number of electrical connector modules are then stacked upon one another such that the conductive terminals 16 of one electrical connector module are in electrical contact with the conductive terminals 16 of an adjacent other electrical connector module to form an electrical connector. It should be noted that this process may be performed by the user or may be performed by the provider according to the needs of the user, i.e. the provider may provide the pre-assembled components to the user.
The drive element 18 of each electrical connector module is then operated to drive the spring clip 14 to open its respective insertion channel 114;
next, the wires 2 with the wire stripper terminals are respectively inserted into the insertion channels 114 of each electrical connector module;
finally, the actuating element 18 of each electrical connector module is released to actuate the spring clip 14 to close its respective insertion channel 114 while resiliently clamping the wire 2 inserted into the housing 11 against the conductive terminal 16, maintaining the wire 2 in electrical connection with the conductive terminal 16.
In the connection process, any crimping tool is not needed, the electric connection between any number of wires can be realized only by pressing the button, the operation is convenient, and the wires are inserted into the through holes and reliably electrically contacted with the conductive terminals under the action of elastic force, so that the whole electric connection is reliable and stable.
Although 2-way electrical connectors and 4-way electrical connectors are described above, respectively, it will be understood by those skilled in the art that the 2-way electrical connectors and 4-way electrical connectors described above are provided as examples only, and that a suitable number of electrical connector modules 10 may be selected to be assembled to form a multiple electrical connector to achieve electrical connection between any number of wires, depending on the needs of the application.
It should also be noted that while the spring clip and the conductive terminal are described as two separate components in the above embodiments, it should be understood that the two components may be integrally formed, i.e., the spring clip and the conductive terminal may be formed as a single unitary component.
Although the present invention has been described with reference to the accompanying drawings, the examples disclosed in the drawings are intended to illustrate preferred embodiments of the invention and are not to be construed as limiting the invention.
Although a few embodiments of the present general inventive concept have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the general inventive concept, the scope of which is defined in the claims and their equivalents.
