Description

Technical Field

[0001] This invention relates to an electrical connector and an electrical connector assembly, and more particularly to a compact electrical connector and an electrical connector assembly. Background Technology

[0002] Electrical connectors are applicable to a variety of fields. They typically include plug-type connectors and socket-type connectors, which are mated together to form an electrical connector assembly, thereby enabling the transmission of current and signals. To facilitate the mating of plug and socket connectors, guide posts are usually provided on both lateral sides of the plug connector housing, while receiving slots are correspondingly provided on both lateral sides of the socket connector housing. The interaction between the guide posts and receiving slots facilitates the mating of the plug and socket connectors.

[0109] In the following, exemplary embodiments will be described in detail with reference to the accompanying drawings. Although this disclosure is open to various modifications and alternatives, specific embodiments thereof are shown by way of example in the drawings. However, this disclosure should not be construed as limiting itself to the embodiments set forth herein, but rather, this disclosure is intended to cover all modifications, equivalents, and alternatives that fall within the spirit and scope of the embodiments.

[0110] The following will refer to the appendix Figure 1 and attached Figure 2 To illustrate the electrical connector 10 according to this application, in conjunction with reference to... Figure 1 and Figure 2 The diagram illustrates a schematic structure of a plug-type electrical connector 10, which mainly includes a housing 100 and a set of conductive terminals 200. According to one embodiment, the set of conductive terminals 200 may include power terminals 210, signal terminal group 220, and detection terminals 230. The signal terminal group 220 is typically arranged in an array. However, the detection terminals 230 can be omitted depending on the actual application requirements of the connector. Similarly, depending on the actual application requirements of the connector, the power terminals 210 may include a high-voltage side power terminal 210a and a low-voltage side power terminal 210b, and may also include a ground terminal 210c. The ground terminal 210c used to mate with the high-voltage side power terminal 210a can be referred to as the high-voltage side ground terminal; the ground terminal 210c used to mate with the low-voltage side power terminal 210b can be referred to as the low-voltage side ground terminal.

[0111] according to Figure 1 and Figure 2 In the embodiment shown, the housing 100 is typically formed of an insulating material and includes a base 110 and a guide portion 120. However, the housing can also be formed of other suitable materials, for example, by molding plastic and metal portions together. The base 110 is provided with a plurality of terminal channels 112 (for simplicity, only some of the terminal channels 112 are shown in the figures), which extend from the rear surface 116 of the base 110 to its front surface 115, as described in conjunction with the accompanying drawing. Figure 4 As shown, the terminal channel 112 is formed in an inverted U-shape with an open bottom at the rear surface 116, and in the form of a slot at the front surface 115, including a first portion 112a located at the upper part and a second portion 112b located at the lower part, and a third portion 112c located between the first portion 112a and the second portion 112b, as shown. Figure 1 As shown, the first portion 112a and the second portion 112b are relatively narrow, while the third portion 112c is relatively wide. This facilitates the insertion of the conductive terminal 200 and also provides positioning and support for the conductive terminal 200. Alternatively, a shoulder or protrusion can be provided on the inner wall of the terminal channel 112 to assist in the positioning and support of the conductive terminal 200. Figure 2 As shown, each conductive terminal 200 is inserted into a corresponding terminal channel 112 on the rear surface 116 of the base 110, and the contact end 201 of each conductive terminal 200 extends from the front surface 115 of the base 110 after passing through the terminal channel 112.

[0112] In addition, the base 110 may also be provided with a compartment 118, such as Figure 1 and Figure 2 As shown, the compartment 118 extends forward from the front surface 115 of the base 110 and communicates with the corresponding terminal channel 112 (e.g. Figure 4 (As shown in the diagram). A signal terminal group 220, consisting of multiple signal terminal arrays, is disposed in the compartment 118. (As shown in the diagram). Figure 1 As shown, the compartment 118 and the terminal channel 112 can also be connected via multiple spacer slots 1182. Thus, each row of signal terminals can be inserted from the terminal channel 112 through the rear surface 116 of the base 110 and then passed through the respective spacer slots 1182 to be accommodated in the compartment 118. The spacer slots 1182 can be, for example, elongated slots extending from top to bottom, allowing an entire row of signal terminals to pass through. Figure 1 As shown, the low-voltage side power supply terminal 210b is provided on the left side of the adjacent signal terminal group 220, and the high-voltage side power supply terminal 210a is provided on the right side of the adjacent signal terminal group 220, but this is not a limitation.

[0113] In addition, refer to Figure 1 and Figure 2 As shown, the electrical connector 10 according to this application is further provided with a guide portion 120, which can move along the transverse direction of the base 110. Figure 1The guide portion 120 may be disposed on both sides of the base 110 (in the left-right direction), or it may be disposed on only one side, for example, only on the left or right side. In other embodiments, the guide portion 120 may also be disposed laterally along the base 110 at the middle of the base or at a position slightly off-center from the middle of one side. Figure 1 The front-to-back direction extends forward to form the mating end 121. Figure 2 (As shown in the diagram), the distance D from the mating end 121 to the front surface 115 of the base 110 is greater than the distance d1 from the contact end 201 of each conductive terminal 200 to the front surface 115, and also greater than the distance d1 along the spacer 118. Figure 1 The distance d2 extending forward from the front surface 115 in the front-rear direction. That is, the guide portion 120 extends the greatest distance from the front surface 115 of the base 110, so that the electrical connector 10 and the mating electrical connector 30 (in Figure 12 , 13 (As shown in the diagram) During docking, the guide portion 120 can serve a guiding function. To better achieve this guiding function, the mating end 121 of the guide portion 120 is also provided with a guiding slope 121a. (See diagram) Figure 1 and Figure 2 As shown, guide slopes 121a can be provided at both the upper and lower ends of the mating end 121, but this is not a limitation. For example, guide slopes 121a can be provided on both the left and right sides of the mating end 121.

[0114] The guide portion 120 also has a mounting groove 124 on its side for inserting the conductive terminal 200. Figure 1 and Figure 2 The diagram shows that both sides of the guide portion 120 are provided with mounting grooves 124. However, depending on actual needs, mounting grooves 124 can also be provided on only one side of the guide portion 120. The mounting grooves 124 are connected to the terminal channel 112, so that after the conductive terminal 200 is inserted into the terminal channel 112, part of it is disposed in the terminal channel 112 and part is disposed in the mounting grooves 124, such as... Figure 2 As shown in the figure.

[0115] The guide portion 120 can be a partition with a certain thickness, or it can be two partitions spaced apart, with an insulator filling between the two partitions. It is not limited to these limitations, as long as the creepage distance between the conductive terminal 200 located on the side of the guide portion 120 and its adjacent conductive terminal is sufficient. According to this application, the guide portion 120 provides guidance when the electrical connector 10 mates with the mating electrical connector 30. Simultaneously, since a mounting groove 124 is provided on one or both sides of the guide portion 120, the conductive terminal 200 can be inserted into the mounting groove 124. Therefore, while achieving the guiding function, the guide portion 120 does not increase the overall lateral width of the electrical connector 10, and through the thickness of the guide portion 120, the conductive terminals 200 on both sides of the guide portion 120 can meet the creepage distance requirements.

[0116] like Figure 1 and Figure 2 As shown, the top of the guide portion 120 is also provided with a groove 123 extending in the front-rear direction. Figure 7 , Figure 8 , Figure 11 , Figure 12 The groove 123 is also shown in the diagram (and will not be described again hereafter). The groove 123 can extend rearward from the top of the guide portion 120 to the top of the base 110, but is not limited thereto. Similarly, a groove 123 extending in the front-rear direction can be provided at the bottom of the guide portion 120. The groove 123 can extend rearward from the bottom of the guide portion 120 to the bottom of the base 110, but is not limited thereto. The groove 123 can further increase the creepage distance between the conductive terminals 200.

[0117] In addition, refer to Figure 7 As shown, the Figure 7 This diagram illustrates the structure of an electrical connector 10 according to another embodiment. The guide portion 120 includes a first guide portion 120a disposed at the right end of the base 110 and a second guide portion 120b disposed at the left end of the base 110. According to this embodiment, Figure 7 The left side of the base 110 is provided with a low-voltage side power terminal 210b, while the right side of the base is provided with a high-voltage side power terminal 210a. Based on safety regulations, the higher the voltage, the greater the creepage distance. Therefore, the width of the first guide portion 120a is greater than the width of the second guide portion 120b, thus satisfying the creepage distance requirements of both the high-voltage side power terminal 210a and the low-voltage side power terminal 210b.

[0118] Back to the appendix Figure 1 and attached Figure 2The base 110 is also provided with a support arm 117, which extends forward from the front surface 115 of the base 110, and the distance D between the mating end 121 of the guide portion 120 and the front surface 115 of the base 110 is also greater than the distance D along the support arm 117. Figure 1 The distance d3 extending forward from the front surface 115 in the front-back direction. Figure 2 (As shown in the diagram) to ensure that the guiding function of the guide portion 120 is not interfered with. Considering that the grounding terminal 210c on the high-voltage side is typically large, this support arm 117 can be used to support the grounding terminal 210c on the high-voltage side, but is not limited thereto. Specifically, as... Figure 1 and Figure 2 As shown, a slot 1171 can be provided on either side of the support arm 117, in conjunction with reference to the reference. Figure 4 After the high-voltage side grounding terminal 210c is inserted into the terminal channel 112 from the rear surface 116 of the base 110, part of the high-voltage side grounding terminal 210c is located in the terminal channel 112 and part is inserted into the slot 1171 so that the grounding terminal 210c can be better positioned and supported by the support arm 117.

[0119] In addition, such as Figure 8 As shown, the Figure 8 To illustrate the structure of the electrical connector 10 according to another embodiment, in the illustrated embodiment, the grounding terminal 210c can be divided into a first grounding terminal 210c1 and a second grounding terminal 210c2 according to actual needs. The first grounding terminal 210c1 and the second grounding terminal 210c2 can be spaced apart along the vertical direction, such as... Figure 8 As shown, but not limited to this, it can also be set at intervals along the left and right directions to meet different grounding requirements.

[0120] Return to the reference appendix Figure 1 and attached Figure 2 The electrical connector 10 may also be equipped with a detection terminal 230 as needed, but the detection terminal 230 can be omitted depending on actual requirements. Figure 1 and Figure 2 In the illustrated embodiment, the detection terminal 230 is also disposed in the compartment 118 and located beside the signal terminal group 220. A partition wall 1181 (e.g., between the detection terminal 230 and the signal terminal group 220) is provided between them. Figure 1 A partition wall 1181 extending vertically is provided between the detection terminals 230 (e.g., a partition wall 1181). Figure 1 The spacer 1181 extends along the left and right sides. The spacer 1181 can protect the signal terminals and the detection terminals 230, and can also further increase the creepage distance.

[0121] Next, refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 Description of an electrical connector 10 according to another embodiment, wherein Figure 3 and Figure 4 Both images show the conductive terminal 200 not assembled into the housing 100. Figure 3 This is a view taken from the front of the electrical connector 10, and Figure 4 This is a view taken from the rear of the electrical connector 10; Figure 5 The diagram shows the conductive terminal 200 assembled into the housing 100, while Figure 6 The structure of the power terminal 210 and the detection terminal 230 according to this embodiment is shown. In this embodiment, the detection terminal 230 is no longer disposed in the compartment 118, but is integrated with the power terminal 210 at the same potential, for example, by being connected as a single unit through insert molding. Since the power terminal 210 and the detection terminal 230 at the same potential do not require consideration of creepage distance, they can be directly integrated. Preferably, when the current carried by the high-voltage side power terminal 210a is less than the current carried by the low-voltage side power terminal 210b, the detection terminal 230 and the high-voltage side power terminal 210a at the same potential can be integrated. This is because the cross-sectional area of ​​the low-current power terminal 210 is smaller, thus providing sufficient space for the detection terminal 230, thereby further optimizing the use of limited space. Furthermore, according to this embodiment, since the detection terminal 230 and the power terminal 210 at the same potential are connected as a single unit through insert molding, the width of the electrical connector 10 in the left-right direction can be further reduced.

[0122] like Figure 6 As shown, the detection terminal 230 may be located below and in front of the high-voltage side power supply terminal 210a, but is not limited thereto. The distance between the contact end of the detection terminal 230 and the front surface 115 of the base 110 is less than the distance between the contact end of the high-voltage side power supply terminal 210a and the front surface 115 of the base 110.

[0123] The remaining structure of the electrical connector 10 in this embodiment is the same as... Figure 1 and Figure 2 The electrical connector shown in the figure has the same structure and will not be described again.

[0124] Next, please refer to the appendix. Figure 9 and attached Figure 10 The structure of the electrical connector 10 according to another embodiment is described. In this embodiment, the base 110 is further provided with a second support arm 119, which is located between the support arm 117 and the guide portion 120 located on the right side of the base 110. Similarly, the distance D between the mating end 121 of the guide portion 120 and the front surface 115 of the base 110 (in...) Figure 2(As shown in the diagram) is also greater than the distance d4 that the second support arm 119 extends from the front surface 115 in the front-rear direction (in Figure 9 (As shown in the diagram) to ensure that the guiding function of the guide portion 120 is not interfered with. Furthermore, in this embodiment, a mounting groove 124 is provided on the right side of the right guide portion 120 away from the second support arm 119, and a portion of the front surface 115 of the protruding base 110 of the power terminal 210 is disposed in the mounting groove 124, while no mounting groove or power terminal is provided on the left side of the right guide portion 120; a second slot 1191 is provided on the left side of the second support arm 119 away from the right guide portion 120, and a portion of the front surface 115 of the protruding base 110 of the power terminal 210 is inserted into the second slot 1191, that is, the power terminal 210 is partially located in the terminal channel 112 and partially inserted into the second slot 1191. In this embodiment, the provision of the second support arm 119, and the provision of the power terminal 210 on the left side of the second support arm 119 and the right side of the guide portion 120 respectively, provides a more sufficient creepage distance, meeting the requirements for high creepage distances.

[0125] The remaining structure of the electrical connector 10 in this embodiment is the same as... Figure 1 and Figure 2 The structure of the electrical connector shown in the figure or Figure 3 The electrical connector shown in the figure has the same structure and will not be described again.

[0126] Then refer to the appendix Figure 11 and attached Figure 12 According to another embodiment of the electrical connector 10, in this embodiment, the base 110 is further provided with a third support arm 113, which is located at a position corresponding to the low-voltage side power terminal 210b. Similarly, the distance D between the mating end 121 of the guide portion 120 and the front surface 115 of the base 110 is (in...) Figure 2 (As shown in the diagram) is also greater than the distance d5 that the third support arm 113 extends forward from the front surface 115 in the front-rear direction (in Figure 12(As shown in the diagram) to ensure that the guiding function of the guide portion 120 is not interfered with. Furthermore, in this embodiment, third slots 1131 are provided on both the left and right sides of the third support arm 113. The low-voltage power terminal 210b is partially inserted into the terminal channel 112 and partially into the third slot 1131 on the left side, while the low-voltage ground terminal 210c is partially inserted into the terminal channel 112 and partially into the third slot 1131 on the right side. According to this embodiment, by mounting a single low-voltage power terminal 210b and a single low-voltage ground terminal 210c on both sides of the third support arm 113, the length of the electrical connector 10 in the left-right direction can be effectively reduced. For example, in high-current applications on the low-voltage side, if the standard low-voltage side power terminal 210b consists of two plate-shaped terminals, assuming its rated current carrying capacity is M amperes, and if the rated current of the high-current application on the low-voltage side of the electrical connector is 4.5*M amperes, then four standard low-voltage side power terminals 210b and a single plate low-voltage side power terminal 210b can be used. Similarly, the low-voltage side ground terminal 210c is used. Using the above structure, mounting the single plate low-voltage side power terminal 210b and the single plate low-voltage side ground terminal 210c on both sides of the third support arm 113 not only meets the practical application requirements for high current, but also effectively reduces the length of the electrical connector 10 in the left-right direction compared to using five standard low-voltage side power terminals and five standard low-voltage side ground terminals to achieve the same application requirements.

[0127] The remaining structure of the electrical connector 10 in this embodiment is the same as... Figure 1 and Figure 2 The structure of the electrical connector shown in the figure or Figure 3 The electrical connector shown in the figure has the same structure and will not be described again.

[0128] The following text will refer to the appendix. Figure 13 and attached Figure 14 According to the description of the electrical connector assembly 1 of this application, the electrical connector assembly 1 includes a plug-type electrical connector 10, which can be the type described above corresponding to the attached... Figure 1 -Appendix Figure 12 The illustrated embodiment includes an electrical connector 10. Furthermore, the electrical connector assembly 1 also includes a mating electrical connector 30, through which power and signal transmission can be accomplished via the mating of the electrical connector 10 and the mating electrical connector 30. (See attached image.) Figure 13 The image shows the electrical connector 10 and the mating electrical connector 30 before they are mated together, while the attached... Figure 14 The diagram shows the electrical connector 10 and the mating electrical connector 30 after they are mated together.

[0129] Combined with reference to the appendix Figure 15 and attached Figure 16The diagram illustrates a schematic structure of a mating electrical connector 30, which also includes a mating housing 300 and mating conductive terminals 400. After the mating electrical connector 30 mates with the electrical connector 10, the mating conductive terminals 400 and conductive terminals 200 form electrical contact to achieve power and signal transmission. The mating housing 300 is also provided with mating terminal channels, and the mating conductive terminals 400 are correspondingly disposed in each mating terminal channel. Corresponding to the conductive terminals 200 of the electrical connector 10, the mating conductive terminals 400 may also include mating power terminals 410, mating signal terminal groups 420, and mating detection terminals 430. The mating signal terminal groups 420 are usually arranged in an array. Of course, the mating detection terminals 430 may be omitted depending on the different embodiments of the electrical connector 10. Similarly, corresponding to the electrical connector 10, the mating power terminals 410 may include high-voltage side mating power terminals 410a and low-voltage side mating power terminals 410b, and may also include mating ground terminals 410c. The grounding terminal 410c includes: a grounding terminal on the low-voltage side corresponding to the grounding terminal on the low-voltage side and a grounding terminal on the high-voltage side corresponding to the grounding terminal on the high-voltage side.

[0130] Furthermore, corresponding to the structure of the electrical connector 10, the mating electrical connector 30 may further include: a guide receiving portion 330, which communicates with the mating terminal channel and is used to receive the guide portion 120 of the electrical connector 10; and a conductive terminal receiving portion 340, which communicates with the mating terminal channel and is used to receive the conductive terminal 200 of the electrical connector 10. Based on the specific structure of the electrical connector 10, the mating electrical connector 30 may further include: a support arm receiving portion 350, which is used to receive the support arm 117 of the electrical connector 10; and a signal terminal group mating portion 360, which is used to mate with the signal terminal group 220 of the electrical connector 10 to achieve mating, and when the electrical connector 10 and the mating electrical connector 30 are mated, the signal terminal group mating portion 360 is housed in the compartment 118 of the electrical connector 10.

[0131] In the appendix Figure 15 and attached Figure 16 In this embodiment, only one support arm receiving portion 350 is provided. Of course, corresponding to other different embodiments of the electrical connector 10, the mating electrical connector 30 may also be provided with a second support arm receiving portion and a third support arm receiving portion to receive the second support arm 119 and the third support arm 113 of the electrical connector 10 respectively, and is not limited thereto.

[0132] like Figure 15 and Figure 16As shown, the guide receiving portion 330, the conductive terminal receiving portion 340, and the support arm receiving portion 350 are all disposed on the mating surface 320 of the mating housing 300 and extend from the mating surface 320 toward the interior of the mating housing 300. Clearly, the shape and size of the guide receiving portion 330, the conductive terminal receiving portion 340, and the support arm receiving portion 350 match the shape and size of the corresponding guide portion 120, the conductive terminal 200, and the support arm 117. Furthermore, the type of the mating conductive terminal 400 in each conductive terminal receiving portion 340 also corresponds to the type of the corresponding conductive terminal 200 in the mating electrical connector 10.

[0133] When the electrical connector 10 is provided with a detection terminal 230, the mating electrical connector 30 is also provided with a corresponding detection terminal mating part 370, such as... Figure 15 As shown, the detection terminal mating part 370 is used to mate with the detection terminal 230 of the electrical connector 10 to achieve docking, and when the electrical connector 10 and the docking electrical connector 30 are docked, the detection terminal mating part 370 is housed in the compartment 118 of the electrical connector 10.

[0134] According to this application, the electrical connector 10 has a guide portion 120 arranged laterally in the housing 100, and the power terminals 210 are disposed on both sides or one side of the guide portion 120. Therefore, the guide post disposed in the housing in the prior art can be eliminated, effectively reducing the lateral dimension of the electrical connector 10, while still meeting the creepage distance requirements. In addition, the support arm 117, the second support arm 119, and the third support arm 113 of the electrical connector 10 not only provide support and positioning for the corresponding conductive terminals 200 and ensure the creepage distance requirements of adjacent conductive terminals 200, but also enhance the strength of the housing 100.

[0135] Next, refer to Figure 17 and Figure 18 This description describes a variant embodiment of the plug-type electrical connector according to this application, first referring to... Figure 17 As shown in the schematic diagram, Figure 17 The diagram shows a plug-type electrical connector 10. In this variant embodiment, a signal terminal group 220 is disposed at the other end of the housing 100 opposite to the guide portion 120, and a guide post 130 is disposed at the top of the compartment 118 in which the signal terminal group 220 is housed. That is, according to Figure 17 The variant embodiment shown has the longitudinal direction of the housing 100 as the direction in which each terminal extends (i.e., Figure 17 The longitudinal direction shown in the figure is the front-back direction, and the direction perpendicular to this longitudinal direction is the transverse direction of the housing 100 (i.e., the longitudinal direction is the front-back direction). Figure 17 (as shown in the left-right direction), then one end of the housing 100 along its transverse direction (e.g.) Figure 17The left end of the housing 100 is provided with a guide post 130 at the top of the compartment 118, and the other end of the housing 100 along its transverse direction (e.g.) Figure 17 The right end of the connector 10 is provided with a guide part 120. When the plug-type electrical connector 10 is mated with the mating connector, both the guide post 130 and the guide part 120 can play a guiding role.

[0136] like Figure 17 As shown, the guide post 130 can be semi-cylindrical with a semi-conical front end to facilitate insertion and mating without significantly increasing the overall height of the housing 100. However, this is not a limitation; the guide post 130 can also be cylindrical with a conical front end. The semi-conical or conical front end of the guide post 130 can extend forward along the top surface of the compartment 118 beyond its front surface, thus providing guidance when the electrical connector 10 begins to mate with the mating electrical connector.

[0137] The top surface of the compartment 118 for accommodating the signal terminal group 220 is typically lower than the vertical height of the low-voltage side power terminal 210b, ground terminal 210c, and the base 110 of the housing 100. Therefore, the guide post 130, located at the top of the compartment 118, can better utilize this height difference, achieving a guiding function without increasing or excessively increasing the overall height dimension of the electrical connector 10. Furthermore, compared to the aforementioned embodiment, since the guide portion 120 on one side is omitted, the lateral dimension of the electrical connector 10 can also be effectively reduced (i.e., Figure 17 (The dimensions in the left and right directions are shown in the figure). Of course, this is not a limitation, and the guide post 130 is not necessarily located on the top surface of the compartment 118. Figure 2 When the compartment 118 of the signal terminal block 220 shown is positioned in the middle, the guide post 130 can also be directly mounted on the top surface of the base 110.

[0138] In addition, such as Figure 18 As shown, the Figure 18 The rear side of this variant embodiment of the plug-type electrical connector 10 is shown, as in the foregoing embodiment, such as Figure 1 and Figure 2 As shown, the guide portion 120 extends from the front surface 115 of the base 110 along... Figure 1 The front-to-back direction extends forward to form the mating end 121. Figure 2 (as shown in the image), while according to Figure 18 In the variant embodiment shown, the guide portion 120 can extend forward from the rear surface 116 of the base 110 of the housing 100 all the way beyond the front surface 115 of the base 110. Similarly, the guide portion 120 extends from the front surface 115 of the base 110 (in contrast to the respective conductive terminals 200 and the compartment 118). Figure 17(As shown in the figure) the extension distance is the maximum, so that the guide part 120 can play a guiding role when the electrical connector 10 mates with the mating electrical connector.

[0139] The other structures of the guide portion 120, housing 100 and each conductive terminal 200 are the same as those in the aforementioned embodiments, and repeated content will not be described again.

[0140] Next, refer to Figure 19 The following description of the solder joint arrangement of the high-voltage side power terminal 210a according to this application is applicable to the aforementioned [application / representation]. Figures 1-16 The various embodiments shown are also applicable to [the following]: Figures 17-18 The variant embodiment shown.

[0141] like Figure 19 As shown, for example, the solder feet 212 of the three high-voltage side power terminals 210a are arranged in a non-aligned manner, that is, the solder feet 212 of the three high-voltage side power terminals 210a are staggered. In this way, the distance between the solder feet 212 of adjacent high-voltage side power terminals 210a changes from a straight line when they are aligned to an oblique line (as shown). Figure 19 (As shown by the dashed line in the image), this can increase the creepage distance. Of course, it is not limited to... Figure 19 The solder joint arrangement shown is not limited to any staggered arrangement that increases creepage distance. For example, the distance between the solder joints 212 of the high-voltage side power terminals 210a on both sides could be relatively smaller, while the distance between the solder joints 212 of the middle high-voltage side power terminals 210a could be relatively larger. Or, as shown... Figure 20A and Figure 20B As shown, the solder feet 212 of different high-voltage side power terminals 210a are staggered along their longitudinal direction. For example, the solder feet 212 of the middle high-voltage side power terminal 210a are closer to the front (or rear) side of the housing 100, while the solder feet 212 of the high-voltage side power terminals 210a on both sides are closer to the rear (or front) side of the housing 100. The staggered distance can be increased according to specific needs. Figure 20B Compared to Figure 20A The offset distance between the solder feet 212 of the middle high-voltage side power terminal 210a and the solder feet 212 of the high-voltage side power terminals 210a on both sides has been increased. Figure 20A and Figure 20B The diagram shows that each high-voltage side power terminal 210a has three solder feet 212, but this is not a limitation and each terminal may also have two solder feet 212.

[0142] The following text is in the format of Figure 17 The following description illustrates the bottom structure of the plug-type electrical connector 10 using a variant embodiment of the electrical connector shown as an example. The bottom structure described below is also applicable to the aforementioned... Figures 1-12The electrical connectors 10 of the various embodiments shown are as follows. Figure 21 As shown, the bottom surface 114 (i.e., the surface to be mounted with the PCB) of the base 110 of this plug-type electrical connector 10 has a plurality of spaced-apart protrusions 140 and a plurality of recesses 150. The recesses 150 are lower than the bottom surface 114, that is, the recesses 150 extend from the bottom surface 114 toward the top surface of the base 110. The protrusions 140 are formed / distributed on each of the recesses 150 respectively, and may be flush with or higher than the bottom surface 114. The protrusions 140 and recesses 150 may be evenly distributed on the entire bottom surface 114 of the base 110, or they may be distributed only on a portion of the bottom surface 114. The solder feet of each conductive terminal 200 extend from between adjacent protrusions 140, so that when the electrical connector 10 is mounted on the PCB, the contact area with the PCB can be increased by the protrusions 140, and the strength of the housing 100 can also be increased. Furthermore, the creepage distance between the various conductive terminals 200 can be increased by the arrangement of the protrusions 140 and the recesses 150, and the flatness of the housing 100 can be adjusted during the molding process.

[0143] Next, refer to Figure 22 This describes a variant embodiment of the socket-type mating electrical connector according to this application, wherein the socket-type mating electrical connector 30 is... Figure 17 The plug-type electrical connectors 10 shown are mated together. For example... Figure 22 As shown, the mating electrical connector 30 and Figure 17 Correspondingly, the plug-type electrical connector 10 shown has a mating housing 300 at one end (e.g.) Figure 22 A guide receiving portion 330 is formed at the left end shown in the diagram. This guide receiving portion 330 communicates with the mating terminal channel and is used to receive the guide portion 120 of the electrical connector 10. At the opposite end of the mating housing 300 (e.g., Figure 22 The right end shown in the figure forms a signal terminal group mating part 360, which is used to mate with the signal terminal group 220 of the electrical connector 10 to achieve docking, and when the electrical connector 10 and the docking electrical connector 30 are docked, the signal terminal group mating part 360 is received in the compartment 118 of the electrical connector 10. According to Figure 22 In the illustrated embodiment, a guide post receiving portion 380 is provided above the signal terminal assembly mating portion 360. This guide post receiving portion 380 can be integrally formed with the mating housing 300, and the guide post receiving portion 380 forms a groove 382 opening towards the signal terminal assembly mating portion 360. When the mating connector 30 mates with the electrical connector 10, the guide post 130 of the electrical connector 10 can extend into the groove 382. According to... Figure 22 In the illustrated embodiment, the groove 382 is semi-circular, but it is not limited to this and can be formed in other shapes, as long as it can engage with the guide post 130.

[0144] The other structures and arrangements of the mating connector 30 are the same as those described above. Figures 13-16 The structure and configuration of the shown electrical connector 30 are the same, and the repeated content will not be described again.

[0145] Figure 23 A schematic diagram of the bottom structure of a variant embodiment of an electrical connector 30 of a corresponding socket type according to this application is shown. The bottom structure described below is also applicable to the aforementioned embodiment. Figures 13-16 The various embodiments of the mating electrical connector 30 are shown. For example... Figure 23 As shown, a plurality of spaced-apart protrusions 392 are formed on the bottom surface 390 (i.e., the surface that mounts to the PCB) of the mating housing 300 of the mating connector 30; that is, the protrusions 392 extend from the bottom surface 390 of the mating housing 300. The protrusions 392 may be evenly distributed across the entire bottom surface 390 of the mating housing 300, or they may be distributed only on a portion of the bottom surface 390. Figure 23 In the illustrated embodiment, the protrusions 392 are distributed only on a portion of the docking housing 300 near the docking end. The strength of the docking housing 300 can be increased by the various protrusions 392.

[0146] Next, refer to Figure 24 The bottom surface of the electrical connector 10 and the mating electrical connector 30 after mating according to this application is shown as follows: Figure 24 As shown, the bottom surface of the electrical connector 10 can be electrically connected to the first printed circuit board (PCB) 11, and the first printed circuit board 11 is provided with a first gap 11a. The first gap 11a can be provided at the position on the first printed circuit board 11 corresponding to the high-voltage side power terminal 210a to increase the creepage distance. Figure 24 Two first gaps 11a are shown, but this is not a limitation; other numbers of first gaps 11a may also be provided. According to an embodiment not shown, the bottom surface of the mating electrical connector 30 may also be connected to the second printed circuit board 31, and similarly, a suitable number of second gaps 31a may also be provided on the second printed circuit board 31 at positions corresponding to the high-voltage side power terminals to increase the creepage distance.

[0147] Choose a location, such as Figure 24As shown, the bottom surface of the mating connector 30 is electrically connected to the second printed circuit board 31 at the portion corresponding to the high-voltage side power terminal 210a, while the bottom surface of the mating connector 30 is electrically connected to the flexible busbar 32 at the portion corresponding to the low-voltage side power terminal 210b and the ground terminal 210c. The flexible busbar 32 is then electrically connected to the rigid busbar 33. In this embodiment, the low-voltage side power terminal 210b needs to carry a large current, and the larger the current, the thicker the printed circuit board to which it is electrically connected. This arrangement avoids the high cost associated with directly connecting the low-voltage side power terminal 210b to the printed circuit board, which would increase the thickness of the printed circuit board. Furthermore, by connecting the bottom surface of the mating connector 30 at the portion corresponding to the low-voltage side power terminal 210b to the flexible busbar 32, which is then electrically connected to the rigid busbar 33, assembly tolerance issues can be overcome, thus facilitating installation.

[0148] According to an embodiment not shown, similarly, the portion of the bottom surface of the electrical connector 10 corresponding to the high-voltage side power terminal 210a can also be electrically connected to the first printed circuit board 11, while the portion of the bottom surface of the electrical connector 10 corresponding to the low-voltage side power terminal 210b and the ground terminal 210c can be electrically connected to a flexible busbar, which is then electrically connected to a rigid busbar.

[0149] According to yet another embodiment (not shown), the bottom surface of the mating electrical connector 30 is directly electrically connected to the rigid busbar 33 at the portion corresponding to the low-voltage side power terminal 210b and the ground terminal 210c, or is only electrically connected to the flexible busbar 32. Similarly, the bottom surface of the electrical connector 10 at the portion corresponding to the low-voltage side power terminal 210b and the ground terminal 210c can be directly electrically connected to the rigid busbar, or is only electrically connected to the flexible busbar.

[0150] According to another embodiment (not shown), the bottom surface of the mating electrical connector 30, at the portion corresponding to the high-voltage side power terminal 210a, can be directly electrically connected to the rigid busbar 33, or only electrically connected to the flexible busbar 32, or first electrically connected to the flexible busbar 32, which is then electrically connected to the rigid busbar 33. Similarly, the bottom surface of the electrical connector 10, at the portion corresponding to the high-voltage side power terminal 210a, can be directly electrically connected to the rigid busbar, or only electrically connected to the flexible busbar, or first electrically connected to the flexible busbar, which is then electrically connected to the rigid busbar. (Refer to the following...) Figure 24The following details are illustrated using the bottom-mounted configuration of the electrical connector 30 as an example; these details also apply to the bottom-mounted configuration of the electrical connector 10. The flexible busbar 32 is separated by a partition 36, dividing it into a portion corresponding to the low-voltage power terminal 210b and a portion corresponding to the grounding terminal 210c to prevent short circuits. Correspondingly, two rigid busbars 33 are electrically connected to the two portions of the flexible busbar 32. Furthermore, a spacer protrusion 35 connected to the partition 36 is provided to enhance the strength of the partition 36. The spacer protrusion 35 is laterally (along...) Figure 24 The left-right dimension is greater than its longitudinal dimension (along the left-right direction). Figure 24 (The dimensions in the front-to-back direction). The partition wall 36 and the spacer protrusion 35 can be provided on the bottom surface 390 of the mating housing 300. Furthermore, as... Figure 24 As shown, a sleeve 34 is also provided outside the flexible busbar 32 to ensure the structural integrity of the flexible busbar 32 and to achieve electrical insulation. The sleeve 34 can be a heat-shrinkable sleeve, but is not limited to this. Of course, other methods can also be used to prevent short circuits between adjacent flexible busbars 32, and there are no restrictions here. For example, adjacent flexible busbars can achieve electrical insulation through insulating spacers.

[0151] In practical applications, the mating conductive terminals on the bottom surfaces of the mating electrical connectors 30 and 10, and the connection methods between the conductive terminals and the outside, can be adjusted according to the requirements of the application. When it is necessary to prevent short circuits between adjacent busbars, different methods can also be selected to achieve electrical insulation between adjacent busbars.

[0152] Since the features of the invention can be embodied in various forms without departing from the nature of the invention, it should also be understood that the above embodiments are not limited to any of the details described above, unless otherwise stated, and should be broadly interpreted as falling within the scope defined by the appended claims. Therefore, all modifications and alterations falling within the scope and limits of the claims or equivalents thereof should be covered by the appended claims.
