In this embodiment, the protective cover 500 is removably sleeved on the mount portions 120 and the fasteners 400, the protective cover 500 is partially located between the mount portions 120 and the clamp component 300, the terminal 220 is located in the recess 512, and the installation slot S is formed between the protective cover 500 and the clamp component 300 for the insertion of the circuit board 20, such that during the process of the circuit board 20 inserted into the installation slot S to be aligned with the terminal 220, the protective cover 500 can separate the circuit board 20 from the terminal 220 for preventing the circuit board 20 from hitting the terminal 220, thereby ensuring the terminal 220 not to be damaged by the circuit board 20.
Moreover, the light permeable structure 521 of the second positioning portion 520 of the protective cover 500 can help a user to observe the alignment situation of the feeding terminal 21 of the circuit board 20 and the contact portion 221 of the terminal 220 for facilitating accurate alignment between them. Furthermore, the light permeable structure 521 of the second positioning portion 520 is the magnifier structure, which further facilitates the accurate alignment between the feeding terminal 21 of the circuit board 20 and the contact portion 221 of the terminal 220.
Note that the light permeable structure 521 is not restricted to being merely located at the second positioning portion 520 of the protective cover 500; in some other embodiments, another portion of the protective cover (e.g., one of the connection portions 530) may also have the light permeable structure. Moreover, the light permeable structure 521 of the protective cover 500 is not restricted to being the magnifier structure and may be modified to be merely permeable for light but without magnifying capability in some other embodiments. In one embodiment, the entire protective cover may be made of light permeable material. Alternatively, in another one embodiment, the protective cover may not have the light permeable structure, and the alignment between the feeding terminal of the circuit board and the contact portion of the terminal may be performed after the protective cover is removed.
In this embodiment, the fasteners 400 are located in the protective cover 500 and constrained by the first positioning portion 510 and the second positioning portion 520, such that the fasteners 400 can be properly maintained on the mount portions 120 of the seat body 100 in advance before the electrical connector 10 is assembled with the circuit board 20 for preventing the fasteners 400 from becoming lost.
In addition, before the electrical connector 10 is assembled with the circuit board 20, not only the fasteners 400 but also the clamp component 300 and the elastic component 600 in the electrical connector 10 are integrated onto the seat body 100. Therefore, during the installation of the circuit board 20 onto the seat body 100, the aforementioned components do not need to be mounted individually onto the seat body 100, thereby improving the installation efficiency of the circuit board 20.
Note that the elastic component 600 is an optional component and may be omitted in some other embodiments. In such a case, after the protective cover is removed, the fasteners may be screwed into the threaded holes of the clamp component while keeping contacting the sides of the mount portions located farther away from the clamp component, such that the fasteners can move the clamp component towards the circuit board via threaded structures for allowing the clamp component and the mount portions to clamp the circuit board together.
In this embodiment, the grip portions 532 of the protective cover 500 can facilitate fingers of the user to grip and move the protective cover 500 for removing the protective cover 500. Note that the grip portions of the protective cover are optional structures; in some other embodiments, the protective cover may not have the grip portions but have structures for increasing the friction between the fingers and the protective cover, such as protrusion-recess structures. Alternatively, in another embodiment, the protective cover may have both the grip portions and the protrusion-recess structures.
In this embodiment, the fasteners 400 are sequentially disposed through the through holes 121 of the mount portions 120 and the positioning holes 23 of the circuit board 20 and then are screwed into the threaded holes 314 of the clamp component 300 for fixing the circuit board 20 in position. Compared to a conventional case that the fasteners are sequentially screwed into threaded holes of the support parts and disposed through the clamp component and the positioning holes of the circuit board for fixing the circuit board in position, this embodiment can prevent the support parts from being deformed and damaged after the fasteners are screwed into the support parts.
Note that the quantities of the mount portions 120 of the seat body 100, the threaded holes 314 of the clamp component 300 and the fasteners 400 are not restricted and each may be modified to be one in some other embodiments.
According to the electrical connector as discussed in the above embodiments, the protective cover is removably sleeved on the mount portions and the fasteners, the protective cover is partially located between the mount portions and the clamp component, the terminal is located in the recess, and the installation slot is formed between the protective cover and the clamp component for the insertion of the circuit board, such that during the process of the circuit board inserted into the installation slot to be aligned with the terminal, the protective cover can separate the circuit board from the terminal for preventing the circuit board from hitting the terminal, thereby ensuring the terminal not to be damaged by the circuit board.
Moreover, the light permeable structure of the second positioning portion of the protective cover can help a user to observe the alignment situation of the feeding terminal of the circuit board and the contact portion of the terminal for facilitating accurate alignment between them. Furthermore, the light permeable structure of the second positioning portion is the magnifier structure, which further facilitates the accurate alignment between the feeding terminal of the circuit board and the contact portion of the terminal.
In this embodiment, the fasteners are located in the protective cover and constrained by the first positioning portion and the second positioning portion, such that the fasteners can be properly maintained on the mount portions of the seat body in advance before the electrical connector is assembled with the circuit board for preventing the fasteners from becoming lost.
In addition, before the electrical connector is assembled with the circuit board, not only the fasteners but also the clamp component and the elastic component in the electrical connector are integrated onto the seat body. Therefore, during the installation of the circuit board onto the seat body, the aforementioned components do not need to be mounted individually onto the seat body, thereby improving the installation efficiency of the circuit board.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present disclosure. It is intended that the specification and examples be considered as exemplary embodiments only, with a scope of the disclosure being indicated by the following claims and their equivalents.
