When the electrical connector is produced, the preformed conductive terminal is embedded in the shell of the housing, and then injection molding is performed to obtain the desired electrical connector.

[0004] However, after the conductive terminal is plastic-molded in the shell, the entire shell encloses the conductive terminal, so the assembly status of the conductive terminal in the shell cannot be visually detected, which easily causes the conductive terminal to tilt and affects the normal use of the electrical connector.

DETAILED DESCRIPTION

[0031] The following will be combined with the attached Figure 1 To Attachment Fig. 9 The technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] It should be noted that if the directions involved in the embodiments of the present invention are based on those shown in the drawings, if a certain posture changes, the directional indication will also change accordingly.

[0033] Existing electrical connectors usually include a shell and conductive terminals. After the shell is plastic-molded, the conductive terminals are enclosed in the entire shell, so the assembly status of the conductive terminals in the shell cannot be visually detected, which easily causes the conductive terminals to tilt and affects the normal use of the electrical connector.

[0034] In view of this, the inventor provides an electrical connector, aiming to solve the problem that the conductive terminals in the housing cannot be visually inspected in the existing electrical connector, resulting in the conductive terminals being tilted and unable to be promptly checked, thus affecting the normal use of the electrical connector.

[0035] An electrical connector according to the technical solution, such as Figure 1As shown, it includes a conductive terminal 1 and a shell 2, the shell 2 has a hollow inner cavity 21, the hollow inner cavity 21 is arranged inside the shell 2, the conductive terminal 2 is arranged in the hollow inner cavity 21, and part of the conductive terminal 2 is exposed from the bottom of the shell 2 and extends away from the bottom of the shell 2, which is the pin of the conductive terminal 2. The pin is used for welding with an external device, such as a circuit board, and the circuit board has a corresponding welding groove that cooperates with the pin for welding, so that the electrical connector and the circuit board are electrically connected. It can also be used in other household appliances or mobile devices, as long as there are components on the external device that can cooperate with the electrical connector for electrical connection.

[0036] Also like Figure 1 As shown, the housing 2 is provided with an inspection window 22 ; the inspection window 22 is communicated with the hollow inner cavity 21 ; a part of the conductive terminal 2 is exposed through the inspection window 22 .

[0037] It should be understood that a part of the conductive terminal 2 is exposed through the inspection window 22, so that production personnel can visually observe the assembly of the conductive terminal 2, and prevent the occurrence of tilted conductive terminals without timely detection.

[0038] In actual production, the conductive terminals 2 are usually arranged in an array in the shell 1. In order to better observe the assembly status of each conductive terminal 2, each conductive terminal 2 has an inspection window 22 corresponding to the shell 1. Such a design makes it convenient to observe the assembly status of each conductive terminal without missing any conductive terminal 2.

[0039] In this embodiment, the adjacent conductive terminals 2 are arranged in the hollow inner cavity 21 in a staggered manner. Figure 1 As shown, the inspection windows 22 arranged adjacent to this are arranged in a staggered manner up and down.

[0040] It should be understood that the staggered arrangement of the conductive terminals 2 in this embodiment is to bury more conductive terminals 2 in the limited space of the housing 2, so that the electrical connector can support the use of devices with large current or high-speed signal transmission. In addition, the staggered arrangement of the conductive terminals is conducive to preventing the welding points of the conductive terminals 2 between adjacent conductive terminals 2 that are too densely distributed from being connected together, thereby avoiding short circuits in the electrical connector.

[0041] However, in order to observe the assembly status of the conductive terminals 2 arranged in a staggered manner, the inspection windows 22 arranged adjacent to the conductive terminals 2 are arranged in a staggered manner, so that the production personnel can observe the assembly status of each conductive terminal 2 more conveniently.

[0042] For the convenience of observation, further Figure 3 As shown, the lateral width D of the inspection window 22 is greater than the lateral width d of the conductive terminal 1; both sides of the detected portion of the conductive terminal 1 are exposed in the inspection window 22, so that the distribution of the conductive terminal 2 in the inspection curtain 22 can be fully observed.

[0043] Detailed, such as Figure 4 As shown in the figure, the innermost line of the side wall of the inspection window 22 is defined as the first reference line A; the outermost line of the side of the conductive terminal 2 is defined as the second reference line B; from the front view direction, the first reference line A is parallel to the second reference line B. It should be noted that the front view direction is as shown in the figure. Figure 4 The paper shown is viewed from top to bottom.

[0044] In actual usage scenarios, such as Figure 4 In the illustrated embodiment, the cross-section of the inspection window 22 is rectangular, and the cross-section of the conductive terminal 2 is also rectangular. The conductive terminal 2 is disposed in the hollow inner cavity 21. In this embodiment, the first reference line A is parallel to the second reference line B on the conductive terminal 2. Thus, by looking directly at the inspection window 22 from the outside of the inspection window 22, the assembly condition of the conductive terminal 2 disposed in the hollow inner cavity 21 can be observed. As long as the first reference line A is parallel to the second reference line B on the conductive terminal 2, it indicates that the conductive terminal 2 is well assembled and will not be tilted to affect the normal use of the electrical connector.

[0045] In other usage scenarios, such as Figure 5 In the embodiment shown, the cross section of the inspection window 22 is a trapezoid that is enlarged outside and narrow inside, and the conductive terminal 2 is exposed at the narrow part of the inspection window 22. In this embodiment, the innermost side of the side wall of the inspection window 22 is the first reference line A. It should be noted that the first reference line A must be parallel to the central axis C of the inspection window 22. In this embodiment, the central axis C is the longitudinal center symmetry line of the electrical connector, that is, the distances from the longitudinal sides of the electrical connector to the central axis C are equal. In addition, the outermost line of the side of the conductive terminal 2 is defined as the second reference line B. From the outer side 222 of the inspection window 22, the conductive terminal 2 can be observed from the inspection window 22 at a straight-on angle. When the first reference line A and the second reference line B are parallel, it means that the conductive terminal 2 is well assembled in the housing 1 and the conductive terminal 2 will not be tilted.

[0046] In other usage scenarios, such as Figure 6As shown, the cross-section of the inspection window 22 is a parallelogram, and the conductive terminal 1 is arranged in the hollow inner cavity 21. Similarly, the innermost side of the side wall of the inspection window 22 is the first reference line A, and the outermost line of the side of the conductive terminal 2 is the second reference line B. It should be noted that the first reference line A must be parallel to the central axis C.

[0047] This design is to enable the conductive terminal 1 to be visually observed when looking at the inspection window 22 from a straight-on angle. When the first reference line A and the second reference line B are parallel, it means that the conductive terminal 2 is well assembled in the housing 1 and the conductive terminal 2 is not tilted.

[0048] In other usage scenarios, such as Figure 7 As shown, the cross section of the inspection window 22 is rectangular, and a partial area of ​​the conductive terminal 1 is exposed in the inspection window 22 . It should be noted that the partial area of ​​the conductive terminal 2 includes at least one side of the conductive terminal 2 .

[0049] When looking straight at the inspection window 22 from the outside of the inspection window 22, only a part of the conductive terminal 1 can be seen. At this time, the innermost side of the side wall of the inspection window 22 is the first reference line A, and the outermost line of the side of the conductive terminal 2 is the second reference line B. However, when the first reference line A and the second reference line B are parallel, it means that the conductive terminal 2 is well assembled in the housing 1 and the conductive terminal 2 is not tilted.

[0050] It should be noted that the first reference line A is parallel to the central axis C, and for better inspection, the distance between the first reference line A and the second reference line B is at least 1 mm to 3 mm.

[0051] In addition, the above inspection method can also be implemented by scanning with a computer device, such as CCD, etc. The positions of the first reference line A and the second reference line B are preset on the computer, and the assembly status of the conductive terminal 1 can be checked by scanning the first reference line A and the second reference line B to see whether they are parallel.

[0052] Further, such as Figures 8 to 9 As shown, the shell 2 has a first part 23 and a second part 24; the first part 23 and the second part 24 are integrally connected; the thickness of the first part 23 is smaller than the thickness of the second part 24; and the first part 23 has a structure 25 to prevent deformation.

[0053] Detailed, such as Fig. 9As shown, the structure 25 for preventing deformation includes a groove portion 251 and an edge portion 252 ; the groove portion 251 and the edge portion 252 are arranged adjacent to each other.

[0054] It should be understood that in this embodiment, the groove 251 is a long strip-shaped groove that is recessed inward from the surface of the first part 23, and there are at least two grooves 251. The edge 252 is formed between the two grooves 251. The edge 252 in this embodiment can strengthen the strength of the first part 23 and prevent the first part 23 from bending during use.

[0055] In some other embodiments, the groove 251 includes a plurality of grooves 251, and the plurality of grooves 251 are arranged in an array on the first part 23 to increase the strength of the first part 23 and prevent the first part 23 from bending during use.

[0056] Furthermore, the electrical connector also has a fixed terminal 3, which is used for fixing and positioning the electrical connector when it is connected to other devices.

[0057] An electrical connection device includes the electrical connector described above, and uses the electrical connector whose conductive terminals 1 have been inspected to see if they are well assembled, so that the electrical connection device is not easily unusable due to a defective electrical connector.

[0058] According to the disclosure and teaching of the above description, the technical personnel in the field to which the utility model belongs can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
