Description

Technical Field

[0001] This utility model relates to an electrical connector. Background Technology

[0002] In the existing connector terminal assembly process, the terminals are usually pre-installed and then fixed in a preset position by the equipment. For terminals with an arc-shaped bend at one end, the equipment uses a pushing force to forcefully push the terminal for assembly. Because the end of the terminal has an arc-shaped bend, when this end of the terminal is subjected to a hard pushing force, a reverse force will be generated and act on the die molding component. The molding component will be affected by the reverse force and will shift outward, resulting in abnormal terminal 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 provides an electrical connector, comprising: a housing having an internal space and an open side communicating with the internal space; and a plurality of wafers arranged side-by-side and capable of being inserted into the internal space of the housing along a first direction to connect to the housing, each wafer including a terminal group and a molded part fixedly sleeved on the terminal group, the terminal group including a plurality of terminals arranged side-by-side, each terminal having a protruding arcuate bend, the wafer further including two anti-deviation members disposed on two opposite side end faces of the molded part, the anti-deviation members including a main step portion extending outward from the corresponding side end face along a second direction perpendicular to the first direction for insertion into a corresponding rectangular through hole formed on the housing, the main step portion including an elongated main step portion body and an edge formed on the main step portion body along the... A first protrusion at the front end in the first direction and a second protrusion formed at the rear end of the main step body along the first direction, the first protrusion and the second protrusion protrude in opposite directions in a third direction perpendicular to the first direction and the second direction, wherein the protrusion direction of the first protrusion is opposite to the protrusion direction of the arcuate bend of the terminal. The length of the main step body in the first direction is less than the length of the rectangular through hole in the first direction, and the width of the main step body in the second direction is less than the width of the rectangular through hole in the second direction. After the main step body is inserted into the corresponding rectangular through hole, the front end of the main step body abuts against one short side of the rectangular through hole, the first protrusion abuts against one long side of the rectangular through hole, and the second protrusion abuts against the other short side and the other long side of the rectangular through hole. Accordingly, it is possible to prevent the molded part from shifting during the terminal assembly process, thereby preventing poor terminal contact and improving the signal transmission quality of the electrical connector.

[0004] Furthermore, the first protrusion includes a first inclined surface arranged adjacent to the front end face of the front end of the main step body. Accordingly, the arrangement of the first inclined surface not only improves the ease of insertion of the main step into the rectangular through hole, but also facilitates rotation with the first protrusion as a fulcrum.

[0005] Furthermore, the second protrusion includes a second inclined surface arranged on the rear end face away from the rear end of the main step body. Accordingly, the arrangement of the second inclined surface can facilitate the correct positioning of the wafer.

[0006] Furthermore, the height of the main step portion body in the second direction gradually increases from the front end to the rear end of the main step portion body. Accordingly, the gradual change in the height of the main step portion body can guide the insertion of the wafer, thereby improving insertion convenience.

[0007] Furthermore, the main step portions of the two anti-displacement components of the wafer are staggered in the first direction. This improves assembly accuracy and stability.

[0008] Furthermore, the anti-deviation component also includes at least one auxiliary step extending outward from the corresponding side end along the second direction. The at least one auxiliary step is positioned on the same side as the main step. Each auxiliary step includes an elongated auxiliary step body and an auxiliary step protrusion formed at the front or rear end of the auxiliary step body along the first direction and protruding along the third direction. The height of the auxiliary step body in the second direction is less than the height of the main step body in the second direction. Accordingly, this multi-step structure improves the accuracy and convenience of assembly.

[0009] Furthermore, the plurality of wafers includes a first group of wafers and a second group of wafers, which are arranged alternately. At least one auxiliary step portion of each wafer in the first group is positioned on a first side of a main step portion, and the auxiliary step portion protrudes at the front end of the auxiliary step portion body and protrudes in the same protruding direction as the first protrusion of the main step portion. Similarly, at least one auxiliary step portion of each wafer in the second group is positioned on a second side of the main step portion, and the auxiliary step portion protrudes at the rear end of the auxiliary step portion body and protrudes in the same protruding direction as the second protrusion of the main step portion. This improves the applicability of the anti-deviation component design to different types of wafers.

[0010] Furthermore, the main step portion is formed at the corresponding side end face at the edge portion in the third direction. This increases the design space for the anti-deviation component, providing the possibility of providing more auxiliary step portions.

[0011] Furthermore, the housing includes a plurality of terminal mounting slots, each having an open end in the first direction, allowing one terminal of the plurality of wafers to be inserted into the terminal mounting slot. This enables isolation of the individual terminals, thereby improving signal transmission quality.

[0012] Furthermore, the sidewall of the arcuate bend facing the terminal in the terminal mounting groove includes an abutment portion, a recessed clearance portion relative to the abutment portion, and a third inclined surface connecting the abutment portion and the clearance portion, wherein the clearance portion is adjacent to the open end of the terminal mounting groove. Accordingly, during assembly, the terminal first enters the section of the terminal mounting groove with the clearance portion. Because this section has more space, the terminal will not be squeezed and deformed by the inner wall of the terminal mounting groove. Then, the terminal continues to move along the first direction and is guided by the third inclined surface when it contacts it until it finally reaches the section of the terminal mounting groove with the abutment portion for complete assembly. This not only reduces the time the terminal is subjected to compression deformation but also facilitates terminal insertion and reduces the risk of terminal deformation, thereby improving the signal transmission quality of the connector.

[0013] Furthermore, the terminals of the chip are signal terminals or ground terminals. This improves structural adaptability. Attached Figure Description

[0051] The technical solutions of the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0052] In the following detailed description, reference is made to the accompanying drawings, which form a part of this specification, in which specific embodiments of the present invention are illustrated by way of example. 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. Since the components of the embodiments of the present invention can be positioned in many different orientations, the directional terms are for illustrative purposes only and are not intended to be limiting. 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.

[0053] refer to Figure 1 This invention provides an electrical connector 100. The electrical connector 100 generally includes a housing 1 and a plurality of wafers 2. The housing 1 has an internal space and an open side communicating with the internal space. The plurality of wafers 2 are arranged side-by-side and can be inserted into the internal space of the housing 1 along a first direction X to connect to the housing 1.

[0054] refer to Figures 2 to 5 Each chip 2 may include a terminal group 21 and a molded part 22 fixedly sleeved on the terminal group 21, wherein the terminal group 21 includes a plurality of terminals 211 arranged side by side, and each terminal 211 has a protruding arc-shaped bend 211a.

[0055] The wafer 2 may also include two anti-deviation members 23 disposed on two opposing side faces S of the molded member 22. Each anti-deviation member 23 includes a main step portion 231 extending outward from the corresponding side face S along a second direction Y perpendicular to the first direction X, for insertion into a corresponding rectangular through-hole H formed on the housing 1. In other words, the two anti-deviation members 23 extend outward from opposite sides of the wafer 2 to engage with the rectangular through-hole H on the housing 1.

[0056] The main step portion 231 may include an elongated main step portion body 2311, a first protrusion 2312 formed at the front end of the main step portion body 2311 along the first direction X, and a second protrusion 2313 formed at the rear end of the main step portion body 2311 along the first direction X. The first protrusion 2312 and the second protrusion 2313 protrude in opposite directions in a third direction Z perpendicular to the first direction X and the second direction Y. That is, the first protrusion 2312 and the second protrusion 2313 are respectively formed on opposite long sides of the main step portion body 2311 and at two nearly opposite ends. The protrusion direction of the first protrusion 2312 is approximately opposite to the protrusion direction of the arc-shaped bend portion 211a of the terminal, that is, they have approximately opposite extension trends. Based on this, during the terminal assembly process, the terminal may be subjected to a hard pushing force, causing the molded part to be affected by a reverse force and shift outward.

[0057] The length of the main stepped portion 2311 in the first direction X is less than the length of the rectangular through hole H in the first direction X, and the width of the main stepped portion 2311 in the second direction Y is less than the width of the rectangular through hole H in the second direction Y. For example... Figure 8 As best shown, after the main step portion 231 is inserted into the corresponding rectangular through hole H, the front end of the main step portion body 2311 abuts against one short side of the rectangular through hole H (i.e., Figure 8 On the upper short side of the rectangular through-hole H shown in the figure, the first protrusion 2312 abuts against one long side of the rectangular through-hole H (i.e., Figure 8 The second protrusion 2313 abuts against the other short side of the rectangular through-hole H shown in the figure (i.e., the left long side of the rectangular through-hole H), and the second protrusion 2313 abuts against the other short side of the rectangular through-hole H (i.e., the left long side of the rectangular through-hole H). Figure 8 The rectangular through-hole H shown in the image is located on the lower short side and the other long side (i.e., Figure 8 On the right long side of the rectangular through hole H shown in the figure.

[0058] In one embodiment, the first protrusion 2312 may include a first inclined surface S1 arranged adjacent to the front end face of the front end of the main step body 2311. The first inclined surface S1 is inclined at an angle relative to the front end face of the main step body 2311, the angle being between 0 and 90 degrees, preferably between 45 and 60 degrees.

[0059] In one embodiment, the second protrusion 2313 may include a second inclined surface S2 disposed at the rear end face away from the rear end of the main step body 2311. In other words, the second inclined surface S2 is disposed at the front end of the second protrusion 2313 and spaced apart from the rear end face of the main step body 2311. The second inclined surface S2 is inclined at an angle relative to the rear end face of the main step body 2311, the angle being between 0 and 90 degrees, preferably 45 degrees.

[0060] During terminal assembly, especially when the main step portion 231 is inserted into the corresponding rectangular through hole H, the main step portion 231 will rotate around the first protrusion 2312 as a fulcrum through the first inclined surface S1 (such as along...). Figure 7 Rotate in the direction of the arrow shown, so that the second protrusion 2313 abuts against the other short side and the other long side of the rectangular through hole H, and rotate the wafer 2 as a whole to the correct position through the second inclined surface S2, that is, the length direction of the wafer 2 is parallel to the first direction X, so that after assembly, the main step portion 231 can abut against the four sides of the rectangular through hole H to achieve a firm assembly.

[0061] In one embodiment, the height of the main step body 2311 in the second direction Y can gradually increase from the front end to the rear end of the main step body 2311. Of course, the present invention is not limited to this, and the height of the main step body 2311 in the second direction Y can also remain constant.

[0062] In one embodiment, the main step portions 231 of the two anti-displacement components 23 of the wafer 2 can be staggered in the first direction X. Of course, the present invention is not limited to this, and the main step portions 231 of the two anti-displacement components 23 of the wafer 2 can also be aligned with each other.

[0063] In one embodiment, the anti-deviation component 23 may further include at least one auxiliary step portion 232 extending outward from the corresponding side end face S along the second direction Y, such as Figures 2 to 4 As shown, only one auxiliary step portion 232 is illustrated; however, the number of auxiliary step portions 232 can also be multiple. At least one auxiliary step portion 232 is located on the same side of the main step portion 231. Each auxiliary step portion 232 may include an elongated auxiliary step portion body 2321 and an auxiliary step portion protrusion 2322 formed at the front or rear end of the auxiliary step portion body 2321 along the first direction X and protruding along the third direction Z. The height of the auxiliary step portion body 2321 in the second direction Y is less than the height of the main step portion body 2311 in the second direction Y. In particular, in the case of multiple auxiliary step portion protrusions 2322, the height of these auxiliary step portion bodies 2321 decreases progressively in the direction away from the main step portion 231.

[0064] Specifically, the plurality of wafers 2 may include a first group of wafers and a second group of wafers, the first group of wafers and the second group of wafers being arranged alternately to each other. For example... Figure 1 As illustrated, the first group of wafers and the second group of wafers each comprise five wafers, which are arranged alternately one after another. Of course, the number of wafers is not limited to this.

[0065] like Figure 2As best illustrated, at least one auxiliary step portion 232 of each wafer 2 in the first group of wafers can be positioned on a first side of the main step portion 231, and the auxiliary step portion 232 has an auxiliary step portion protrusion 2322 formed at the front end of the auxiliary step portion body 2321 and protruding in the same protruding direction as the first protrusion 2312 of the main step portion 231. At least one auxiliary step portion 232 of each wafer 2 in the second group of wafers can be positioned on a second side of the main step portion 231 (opposite to the first side), and the auxiliary step portion 232 has an auxiliary step portion protrusion 2322 formed at the rear end of the auxiliary step portion body 2321 and protruding in the same protruding direction as the second protrusion 2313 of the main step portion 231.

[0066] In one embodiment, the main step portion 231 may be formed at the edge portion of the corresponding side end face S in the third direction Z, such as in Figure 2 The wafers arranged in the first group of wafers shown.

[0067] In one embodiment, the housing 1 may include a plurality of terminal mounting slots 11, each terminal mounting slot 11 having an open end in the first direction X, such that one terminal 211 of the plurality of wafers 2 can be inserted into the terminal mounting slot 11. In other words, the terminal mounting slots 11 and the terminals 211 are arranged in a one-to-one correspondence. Of course, the present invention is not limited to this; for example, a through-type terminal mounting slot may be provided for all terminals of each wafer, that is, the terminal mounting slots 11 and the terminals 211 are arranged in a one-to-many manner.

[0068] Specifically, the sidewall 111 of the arcuate bend 211a facing the terminal 211 of the terminal mounting groove 11 may include an abutment portion 1111, a relief portion 1112 recessed relative to the abutment portion 1111, and a third inclined surface S3 connecting the abutment portion 1111 and the relief portion 1112, wherein the relief portion 1112 is adjacent to the open end of the terminal mounting groove 11. In other words, the abutment portion 1111, the third inclined surface S3, and the relief portion 1112 of the sidewall 111 are arranged sequentially in the first direction X.

[0069] In addition, the terminal 211 of the chip 2 can be either a signal terminal or a ground terminal.

[0070] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model.
