Description

Technical Field

[0001] This utility model generally relates to the field of electrical equipment, and more specifically to an electrical connector. Background Technology

[0002] The main steps involved in assembling existing electrical connectors are to first pre-install the terminals of the transmission module into the housing, and then push the terminals to fix them in a preset position. For terminals such as those with a beveled end or a bent portion in the insertion section, assembly is achieved by forcibly pushing the terminals. Because the terminal end is beveled or the insertion section of the terminal has a bent portion, when the terminal is subjected to a hard pushing force, a reverse force will be generated and act on the molded part of the transmission module. The molded part will be affected by the reverse force and will shift outward, ultimately leading to abnormal assembly and poor contact. In severe cases, it will affect the signal transmission of the connector. Utility Model Content

[0003] To overcome the aforementioned deficiencies in the prior art, this utility model proposes an electrical connector, comprising: a housing including a base and a sidewall extending from the base; and at least one transmission module inserted into the housing, the transmission module including a molded part and at least one terminal embedded in the molded part, wherein the transmission module further includes at least one guiding component formed on the end face of the molded part, the guiding component including at least one guiding block, and the housing further includes at least one group of guiding grooves formed in the sidewall, the group of guiding grooves including at least one guiding groove for receiving a corresponding guiding block, wherein the guiding block includes at least one guiding surface located at an end and a guiding surface located on the side, and the guiding groove has a mating surface complementary to the shape of the guiding surface, and wherein the guiding surface includes an arcuate segment connected to the top surface of the guiding block and a beveled segment connected to the arcuate segment for positioning and correcting the insertion of the transmission module, and the mating surface includes an arcuate surface and a bevel connected to each other for mating with the arcuate segment and the beveled segment of the guiding surface. Accordingly, guidance and positioning correction can be achieved during the insertion of the transmission module, thereby improving insertion accuracy.

[0004] Furthermore, the inclined section of the guide surface extends inward from top to bottom. This allows for a reduction in the size of the guide block while achieving guidance and positioning correction.

[0005] Furthermore, the guiding surfaces are formed on both opposite sides of the guiding block. This improves the guiding effect on the transmission module.

[0006] Furthermore, the guide block includes a stop portion extending from the guide surface at the side of the guide block, and the guide groove includes a stop groove recessed from the mating surface and conforming to the shape of the stop portion. Accordingly, locking of the transmission module insertion can be achieved, thereby further improving insertion accuracy.

[0007] Furthermore, the electrical connector includes multiple transmission modules. For a portion of these transmission modules, the stop portion of the guide block of the guide assembly is formed on one of the two sides of the guide block, and for another portion of these transmission modules, the stop portion of the guide block of the guide assembly is formed on the other side of the two sides of the guide block. This prevents mis-insertion of different types of transmission modules.

[0008] Furthermore, the alignment component includes a first alignment block and a second alignment block, with the first alignment block positioned in front of the second alignment block, and the first and second alignment blocks offset from each other in a height direction perpendicular to the insertion direction. This improves the alignment effect on the transmission module, thereby further enhancing insertion accuracy.

[0009] Furthermore, the second guide block includes a stop portion extending from the guide surface at a side portion of the second guide block, and the guide groove for receiving the second guide block in the at least one guide groove includes a stop groove recessed from the mating surface and conforming to the shape of the stop portion, wherein the stop portion is positioned at the rear portion of the second guide block. Accordingly, locking of the transmission module insertion can be achieved, thereby further improving insertion accuracy.

[0010] Furthermore, the electrical connector includes multiple transmission modules. For a portion of these transmission modules, the stop portion of the second guide block of the guiding assembly is formed on one of the two sides of the second guide block. For another portion of these transmission modules, the stop portion of the second guide block of the guiding assembly is formed on the other side of the two sides of the second guide block. This prevents mis-insertion of different types of transmission modules.

[0011] Furthermore, the guide surface also includes a vertical section connected to the inclined section, the vertical section being parallel to the insertion direction and perpendicular to the end face of the molded part, wherein the guide block and the guide groove are both dovetail-shaped. This enables more precise locking.

[0012] Furthermore, the vertical segment is connected to the end face of the molded part. This improves the lateral stability of the transmission module within the housing. Attached Figure Description

Regarding the drawings, directional terms such as “top,” “bottom,” “inner,” “outer,” “upper,” “lower,” “front,” and “rear” are used with reference to the orientation of the drawings described.

It should be understood that other embodiments can be used, and structural or logical changes can be made without departing from the scope of the present invention. Therefore, the following detailed description should not be construed as limiting, and the present invention is defined by the appended claims.

[0039] like Figure 1 As shown, this utility model proposes an electrical connector 100. The electrical connector 100 generally includes a housing 1 and at least one transmission module 2 that is inserted into the housing 1. As... Figure 2 As shown, the housing 1 may include a base 11 and a sidewall 12 extending from the base 11. Figure 3 As shown, the transmission module 2 may include a molded part 21 and at least one terminal 22 embedded in the molded part 21. Specifically, the terminal 22 typically includes a plug section, a pin section, and a connecting section connecting the plug section and the pin section. The connecting section of the terminal 22 is held inside the molded part 21. The plug section of the terminal 22 extends from the front of the molded part 21 along the plugging direction X to the outside of the molded part 21, and the pin section extends from the bottom of the molded part 21 to the outside of the molded part 21 along the height direction Y. Figure 2 and Figure 3As shown, the transmission module 2 may further include at least one guiding component 23 formed on the end face of the molded part 21. It should be noted that the so-called end face is the surface located at the end of the molded part 21 in the height direction Y, which is perpendicular to the insertion direction X. The guiding component 23 may include at least one guiding block, and the housing 1 may further include at least one group of guiding grooves formed in the sidewall 12, each group of guiding grooves including at least one guiding groove 13 for receiving a corresponding guiding block. Figure 4 As shown, the guide block may include at least one guide surface 231 located at an end (such as the front end in the insertion direction) and a guide surface 232 located on the side. The guide groove 13 may have a mating surface 131 complementary to the shape of the guide surface 232. The guide surface 232 may include an arcuate segment 2321 connected to the top surface of the guide block and a beveled segment 2322 connected to the arcuate segment 2321 for positioning and correcting the insertion of the transmission module 2. The mating surface 131 may include an arcuate surface and a bevel connected to each other for mating with the arcuate segment 2321 and the beveled segment 2322 of the guide surface 232. In this invention, a guide block with this shape is particularly advantageous for guiding and correcting the positioning during the insertion process of the transmission module 2. During the insertion of the transmission module 2, the end of the guide block with at least one guide surface 231 is first inserted into the corresponding guide groove 13. Because of the presence of the guide surface 231, the end of the guide block itself has a tapered shape. Therefore, even if the transmission module 2 has a certain degree of offset, the end of the guide block can be inserted into the corresponding guide groove 13 without requiring perfectly precise alignment. The guide surface 231 mentioned here can be in the form of a bevel, but this invention is not limited to this; for example, it can also be in the form of an arc surface. As the front end of the guide block is inserted into the corresponding guide groove 13, the portion of the guide block with the guide surface 232 is also inserted into the corresponding guide groove 13. Because of the presence of the arc segment 2321 and the bevel segment 2322 of the guide surface 232, the guide block has a tapered shape. Compared with conventional guide blocks that are usually rectangular, the arc segment 2321 and the bevel segment 2322 can better transmit force, thereby achieving a better guiding effect.

[0040] In one embodiment, the inclined segment 2322 of the guide face 232 extends inwardly from top to bottom. This causes at least a portion of the guide block to have a shape or tendency to taper from top to bottom, thereby ensuring a compact size of the guide block. However, the invention is not limited to this; for example, the inclined segment 2322 of the guide face 232 may also extend outwardly from top to bottom, thereby causing at least a portion of the guide block to have a shape or tendency to expand from top to bottom.

[0041] In one embodiment, guide surfaces 232 can be formed on both opposite sides of the guide block. Accordingly, having guide surfaces 232 on both sides of the guide block along the lateral direction Z not only provides good guiding effect from both sides, thus achieving a superposition of guiding effects, but also makes the structure more stable. Of course, the present invention is not limited to this; for example, it is also feasible to provide a guide surface 232 only on one side of the guide block (i.e., with an arc segment 2321 and a slope segment 2322) and other forms of guide surfaces (e.g., conventionally, only a single planar segment) on the other side.

[0042] In one embodiment, combined Figure 5 and Figure 6 As shown, the guide block may include a stop portion 233 extending from the guide surface 232 on the side of the guide block, and the guide groove 13 includes a stop groove 132 recessed from the mating surface 131 and conforming to the shape of the stop portion 233. Accordingly, when the transmission module 2 is inserted into place, the stop portion 233 of the guide block is inserted into the stop groove 132 and abuts against the side wall of the stop groove 132, thereby achieving final positioning and locking to prevent over-insertion. In this invention, the number of stop portions 233 is not limited. For example, stop portions 233 may be provided on both opposite sides of the guide block, or stop portions 233 may be provided only on one side of the guide block.

[0043] In one embodiment, reference Figure 5 In cases where the electrical connector 100 includes multiple transmission modules 2, and these transmission modules 2 may be of different types, the stop portion 233 of the guide block of the guide assembly 23 of a portion of the transmission modules 2 (i.e., one type of transmission module) can be formed on one side of the two sides of the guide block, and the stop portion 233 of the guide block of the guide assembly 23 of another portion of the transmission modules 2 (i.e., another type of transmission module) can be formed on the other side of the two sides of the guide block. This design serves as a foolproof mechanism. In other words, since the electrical connector 100 may be equipped with different types of transmission modules 2, and since the stop portions 233 of the different types of transmission modules 2 are positioned differently, misinsertion of the transmission modules 2 can be prevented. That is, if an incorrect type of transmission module 2 is inserted, the guide block of that transmission module 2 cannot be fully inserted into the corresponding guide slot 13. More specifically, the electrical connector 100 may include two types of transmission modules, and these two types of transmission modules are arranged alternately with each other, in which case adjacent guiding blocks in two adjacent transmission modules have a radially symmetrical shape (e.g., Figure 5 As shown in the second guide block 23B), and correspondingly, adjacent guide slots in two adjacent guide slot groups also have radially symmetrical shapes (e.g., as shown in the second guide block 23B). Figure 6 (As shown).

[0044] In one embodiment, the guiding component 23 may include two guiding blocks, namely, a first guiding block 23A and a second guiding block 23B, such as... Figure 5 As shown, the first guide block 23A is positioned in front of the second guide block 23B, that is, in front of it in the insertion direction X, and the first guide block 23A and the second guide block 23B are staggered relative to each other in the height direction Y. Accordingly, since guide blocks are provided at both the front and rear of the transmission module 2, the guiding effect can be superimposed, thereby further improving the insertion accuracy. Correspondingly, the guide slot group also has two guide slots. During the insertion process of the transmission module 2, the first guide block 23A and the second guide block 23B are respectively inserted into these two guide slots. Of course, this invention is not limited to this. For example, the transmission module 2 may have one guide block or more than two guide blocks, and the multiple guide blocks do not necessarily have to be arranged in a straight line in the insertion direction X; they can also be arranged in a staggered distribution.

[0045] Specifically, when the guiding component 23 of the transmission module 2 has a first guiding block 23A and a second guiding block 23B, the second guiding block 23B may include the aforementioned stop portion 233, and the guiding groove 13 in at least one guiding groove 13 for receiving the second guiding block 23B may include the aforementioned stop groove 132. In this case, flexible guidance and dynamic correction can be achieved by the first guiding block 23A, and rigid verification and final locking can be achieved by the stop portion of the second guiding block 23B. The two work together to provide a solution for error prevention and offset prevention. More specifically, the stop portion 233 may be positioned at the rear of the second guiding block 23B. Accordingly, by setting the guiding block with the stop portion 233 at the relatively rear of the transmission module 2, the transmission module 2 can be guided during a relatively longer insertion stroke, that is, the transmission module can be guided more fully.

[0046] Furthermore, when the electrical connector 100 includes multiple transmission modules 2, the stop portion 233 of the second guide block 23B of the guide assembly 23 of a portion of the transmission modules 2 can be formed on one of the two sides of the second guide block 23B, and the stop portion 233 of the second guide block 23B of the guide assembly 23 of another portion of the transmission modules 2 can be formed on the other side of the two sides of the second guide block 23B. This prevents mis-insertion of different types of transmission modules.

[0047] In one embodiment, the guide surface 232 may further include a vertical segment 2323 connected to the inclined segment 2322. The vertical segment 2323 is parallel to the insertion direction X and perpendicular to the end face of the molded part 21. The guide block and the guide groove are both dovetail-shaped. Specifically, the vertical segment 2323 is connected to the end face of the molded part 21. In other words, the curved segment 2321, the inclined segment 2322, and the vertical segment 2323 are arranged sequentially from the top to the bottom of the guide block, allowing the guide block to have a shape that first tapers and then remains constant (wherein, the inclined segment 2322 extends inwardly from the top to the bottom). In this case, during the alignment of the transmission module 2, the inclined segment 2322 can perform guiding and coarse adjustment, while the vertical segment 2323, as the final positioning reference, fits tightly with the vertical segment in the mating surface of the corresponding guide groove, eliminating all gaps and degrees of freedom caused by the inclined surface, thereby achieving precise locking with zero gap in the lateral direction Z. This vertical segment 2323 design provides a larger contact area and friction, which greatly enhances the lateral stability of the transmission module in the housing. It can effectively resist vibration, impact or insertion and extraction forces during use, prevent the transmission module from shaking slightly, and thus ensure the long-term stability and conductivity reliability of the terminal connection.

[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
