Abstract
Description
Technical Field
[0001] This utility model relates to an electrical connector that is combined with a mating connector. Background Technology
[0002] Typically, when substrates are interconnected, two connectors are used to connect to each substrate via methods such as soldering. These two connectors can be connected to each other. Here, one of the two connectors is a plug connector, and the other is a receptacle connector. The receptacle connector can also be called a receptacle connector. Such plug connectors and receptacle connectors can be formed by arranging terminals in a mold section. The plug connectors and receptacle connectors can be fastened together to form an electrical connector assembly.
[0003] With the trend towards miniaturization in electronic devices, the miniaturization and lower back profile of connectors is also a trend. However, in reality, there are certain limitations in reducing pitch or making parts smaller to achieve miniaturization and lower back profile of connectors.
[0004] On the other hand, while connectors are miniaturized, there are also aspects where ensuring their durability is more difficult than before. This is because the smaller components are more susceptible to breakage or deformation even under smaller forces.
[0005] Furthermore, as a type of deformation, plastic deformation may occur if the metal terminals maintain a specific shape during the connection process or while already connected between connectors. Plastic deformation, the opposite of elastic deformation, refers to a state where the material does not return to its original shape and remains deformed even after the load applied to it is removed. This is because all materials are generally elastic, but their shape deforms under stress. For the increasingly miniaturized connector terminals, there is a need to prevent this type of plastic deformation.
[0006] Furthermore, there are cases where resin molds (housings) for connectors are made using insert molding. In such cases, the correct molding of the housing depends on the fluidity of the resin, thus necessitating the improvement of resin fluidity.
[0007] In addition, when manufacturing terminals made of metal, there are usually limitations on the structure of the terminal itself and the resin mold depending on the manufacturing method (e.g., whether deep drawing is used), so it is necessary to take this point into consideration.
[0008] In addition, in insert molding and other processes, it is necessary to consider the issue of resin injection molding covering metal materials. Utility Model Content

[0084] The advantages and features of this invention, as well as the methods for achieving these advantages and features, will become apparent from the accompanying drawings and the embodiments described in detail below. However, this invention is not limited to the embodiments disclosed below, but is implemented in various different forms, and these embodiments are provided only to complete the disclosure of this invention and to fully convey the scope of the invention to those skilled in the art to which it pertains, and this invention is defined only by the scope of the claims. Throughout the specification, the same reference numerals refer to the same constituent elements.
[0085] Figure 1 This is a perspective view of an example of a plug connector (10) in an electrical connector according to the present invention.
[0086] In this specification, the term "electrical connector" may be used as "plug connector (10)" as appropriate, "socket connector (not shown)" (also called "socket connector") as appropriate, or "both plug connector (10) and socket connector (not shown) (or an assembly thereof) as appropriate.
[0087] exist Figure 1 As an example, the diagram shows the fittings (10-1) (also called fitting terminals), signal terminals (10-3), and housing (10-5; mold part) of the plug connector (10). While not limited to this, Figure 1 In the example, the fitting (10-1) can also serve as a power terminal (10-1).
[0088] The fitting (10-1) is a metal structure used to supplement the strength of the connector (10). The power terminal (10-1) allows for the input and output of power signals. As described above, in Figure 1 In this example, the fitting (10-1) also serves as the power terminal (10-1). However, this invention does not preclude the fitting (10-1) and the power terminal (10-1) from being formed separately.
[0089] The signal terminal (10-3) can input and output data signals.
[0090] exist Figure 1 In the process, the fittings (10-1) and the power terminals (10-1) are not separated and are made as one piece.
[0091] Alternatively, for example, the signal terminal (10-3) can also consist of four pins that allow a current of 0.3A, and can function as a power supply terminal by allowing a current exceeding 0.3A, such as 5A. However, having four pins is just one example. For reference, in Figure 1 In the example, there are 24 signal terminals (10-3).
[0092] The housing (10-5) has a base (10-5-B). The housing (10-5) has a wall portion protruding from the upper surface of the base portion, and hardware (10-1), power terminal (10-1), signal terminal (10-3), etc. are formed on the wall portion.
[0093] The wall is generally formed by four parts, including the first wall (10-5-W1), the second wall (10-5-W2), the third wall (10-5-W3), and the fourth wall (10-5-W4). For example... Figure 1 As shown, the components are connected in the following order: first wall portion (10-5-W1) - second wall portion (10-5-W2) - third wall portion (10-5-W3) - fourth wall portion (10-5-W4), with the fourth wall portion (10-5-W4) connecting to the first wall portion (10-5-W1) again. Figure 1 In the connector, it is roughly rectangular, with the first wall (10-5-W1) and the third wall (10-5-W3) as side walls, and the second wall (10-5-W2) and the fourth wall (10-5-W4) as end walls.
[0094] The housing (10-5; mold part) of the plug connector (10) is preferably made of plastic, such as liquid crystal polymer (LCP). Alternatively, the housing (10-5) may be formed of an insulator including resin and epoxy resin, but is not limited thereto. The power terminal (10-1) and signal terminal (10-3) of the plug connector (10) are preferably made of metal, but are not limited thereto; for example, copper may be used, and the copper alloy may be gold-plated (with a nickel underlayer).
[0095] When viewed with reference to a sidewall (e.g., the first wall portion (10-5-W1)), it can be seen that the signal terminals (10-3) use a mixture of two arrangements (as an example, signal terminals (10-3) of the same shape of one type are arranged in two different ways only by changing their orientation). That is, although not limited to this, Figure 1As the signal terminals (10-3) move along the length direction (X direction) of the connector (10), the mounting portions (10-3-M) are arranged alternately, one time on the outside of the connector width direction and the other time on the inside of the connector width direction (visible through the through hole (10-5-PH)). Furthermore, for the multiple mounting portions (10-3-M) located inside the connector (10) width direction (Y direction), the mounting portions (10-3-M) of the signal terminals (10-3) on the first wall portion (10-5-W1) and the mounting portions (10-3-M) of the signal terminals (10-3) on the third wall portion (10-5-W3) are also arranged in a sawtooth pattern. Therefore, since the mounting pitch is not necessarily based on the pitch of the signal terminals (10-3) (the mounting pitch is approximately twice the pitch of the signal terminals (10-3)), many signal terminals (10-3) can be placed in a narrow space.
[0096] Figure 2 Will Figure 1 The plug connector (10) is disassembled and shown.
[0097] If Figure 1 The plug connector (10) is disassembled and shown, as follows: Figure 2 Generally, but with the general Figure 2 Compared to manufacturing the parts separately and then assembling them, there is a preferred manufacturing sequence as shown below. The parts can be... Figure 2 It can be understood as a conceptual diagram used to help understand the structure.
[0098] exist Figure 1 The document describes the power terminal (10-1) (fittings), signal terminal (10-3), and housing (10-5) (mold part). However, the housing (10-5) is not a single piece of material. Figure 2 The shell (10-5) is divided into at least three parts. That is, the shell (10-5) includes a left half (10-5-L), a right half (10-5-R) (half-body wall part (10-5-H)), and a shell end (10-5-E) (body wall part).
[0099] Although it is shown as the left half (10-5-L) / right half (10-5-R) when distinguishing left / right, the left half (10-5-L) and / or the right half (10-5-R) may be referred to as the half-wall portion (10-5-H) when it is not necessary to clearly distinguish left / right.
[0100] Although only by Figure 2 Not explicitly shown, but as an example
[0101] - To position multiple signal terminals (10-3), a single injection molding process (called the first injection molding, also known as the first insert molding) is performed to create the resin left half (10-5-L).
[0102] -Also, the right half of the resin body (10-5-R) is injection molded in a single injection molding process to position multiple signal terminals (10-3).
[0103] - To make the left half (10-5-L), right half (10-5-R), and power terminal (10-1) positioned, a second injection molding (called the second injection molding or the second insert molding) is performed to form the resin shell end (10-5-E).
[0104] As a result, we can obtain the following: Figure 1 A typical plug connector (10), and Figure 2 The structure of this plug connector (10) is shown in disassembly for ease of understanding.
[0105] In Figure 3 The following explanation will be provided, but if... Figure 2 As shown, if the parts are manufactured separately and assembled, it may be difficult to securely fix the joints between them. Therefore, in this invention, the joints are secured securely by determining the order, such as in a single injection molding or a two-stage injection molding process, as described above. The following will describe the connection structure (i.e., the detailed structure of the joints) between the left half (10-5-L), the right half (10-5-R), and the end (10-5-E) of the housing (10-5).
[0106] In the left half (10-5-L) and right half (10-5-R), "left" and "right" are arbitrarily named and do not need to be strictly adhered to. As described above, one or both of them may be referred to as the half-wall part (10-5-H) as needed.
[0107] Furthermore, in the left half (10-5-L) and right half (10-5-R), the term "half" is arbitrarily used and does not necessarily mean "half"; it is sufficient to imply that it constitutes a part. For example, the left half can exist in two columns, and the right half can also exist in two columns. In this case, although strictly speaking it is not a "half" (i.e., 1 / 2) but rather a 1 / 4 block, as mentioned above, the term "half" is not limited to precisely referring to half.
[0108] exist Figure 2 In the middle, the body wall (10-5-E) has an H shape, and specifically, when... Figure 2Based on the reference, the body wall portion (10-5-E) is a single piece (whole piece) that connects the right side portion to the left side portion of the connecting portion (10-5-EC) located in the middle. The body wall portion (10-5-E) is shaped to connect the body wall portions (10-5-E) located near the power terminal (10-1), and the body wall portions (10-5-E) near the power terminal (10-1) are connected by resin to strengthen the bonding force in the secondary insert molding. (The space next to the connecting portion (10-5-EC) (next to the connector (10) in the width direction) is configured as a through hole (10-5-PH) (see reference) Figure 1 It can also be used for visual (camera) inspection, etc.
[0109] Of course, it is not limited to Figure 2 As shown in the diagram, although the possibility of the body wall portion (10-5-E) being in this utility model is not excluded... Figure 2 The middle is separated into two parts, one on the left and one on the right, without a connecting part (10-5-EC), but as shown in the example Figure 2 The present invention will be described based on a typical illustrated example (i.e., an example in which there is a connecting part (10-5-EC) and the body wall part (10-5-E) is a single piece).
[0110] This utility model is a connector (10) formed by the following:
[0111] The half-body wall (10-5-H) provides for multiple signal terminals (10-3) to be arranged along the length of the connector (10);
[0112] The main body wall (10-5-E) is connected to both ends of the half-body wall (10-5-H).
[0113] At this time, the body wall portion (10-5-E) has a base (10-5-B) extending from the wall portion (e.g., the fourth wall portion (10-5-W4)), and a connecting portion (10-5-EC) is formed that extends in the length direction (X direction) of the connector (10) and connects the bases (10-5-B) of the body wall portion (10-5-E) to each other.
[0114] At this time, the half-body wall (10-5-H) is formed by first insert molding (first injection molding) and the body wall (10-5-E) is formed by second insert molding (second injection molding).
[0115] The connecting portion (10-5-EC) is formed simultaneously with the second insert molding (second injection molding) that forms the body wall portion (10-5-E).
[0116] exist Figure 2In the example, the thickness of the base (10-5-B) is the same as the thickness of the connecting part (10-5-EC).
[0117] Moreover, at least two (in the half-body wall portion (10-5-H)) Figure 2 The left half (10-5-L) and the right half (10-5-R) are arranged opposite each other in the width direction (Y direction), and the connecting part (10-5-EC) is located between different half wall parts (e.g., the left half (10-5-L) and the right half (10-5-R)).
[0118] The phrase "at least two hemispheres (10-5-H)" means not limited to, for example, the following. Figure 2 As shown in the diagram, the two halves of the wall (10-5-H) extend in the length direction (X direction) and can interact with... Figure 2 The illustrations differ, for example, showing four or six half-wall portions (10-5-H) extending in the length direction (X direction). Furthermore, although the term "half-wall portion (10-5-H)" is used, it does not necessarily mean "half-body" in the precise sense of half.
[0119] Figure 3 This is a diagram showing a portion of the half-body wall (10-5-H) (particularly the left half-body (10-5-L)).
[0120] Figure 3 The image shows a portion of the left half of the body (10-5-L), and it is... Figure 2 The left half of the body (10-5-L) is shown in a different orientation on the diagram. The left half (10-5-L) and / or the right half (10-5-R) are also referred to as the half-wall portion (10-5-H).
[0121] In Figure 3 When the direction is taken as the reference, it can be seen that the left side of the figure is the outer side of the width direction of the plug connector (10), while the right side of the figure is the inner side of the width direction of the plug connector (10).
[0122] As Figure 3 The shown components include the engagement hole (H1), the first engagement post (C1), and the... Figure 4 The other constituent elements described herein will be discussed below.
[0123] Figure 4 This is a diagram showing a portion of the body wall (10-5-E) (the end of the shell).
[0124] Figure 4 The image shows the end of the shell (10-5-E) (also called the body wall), in which... Figure 2The left side of the diagram is shown by changing its orientation.
[0125] In Figure 4 When the direction is taken as the reference, it can be seen that the left side of the figure is the inner side of the length direction of the plug connector (10), while the right side of the figure is the outer side of the length direction of the plug connector (10).
[0126] As Figure 4 The second engaging post (C2), the third engaging post (C3), and the fourth engaging post (C4) shown are... Figure 3 The components shown (engaging hole (H1), first engaging post (C1), etc.) are combined as detailed below.
[0127] As mentioned above, the premise is... Figure 1 The plug connector (10) (which mates with a jack connector not shown),
[0128] Figure 1 The plug connector (10) is not as Figure 2 The housing (10-5) shown is an injection molded part, comprising at least three separate blocks.
[0129] At this time, the present invention is a connector (10) formed by the following:
[0130] The half-body wall portion (i.e., the left half-body portion (10-5-L) and / or the right half-body portion (10-5-R)) provides for multiple signal terminals (10-3) to be arranged in the length direction (X direction);
[0131] The main body wall (i.e., the shell end (10-5-E)) is connected to both ends of the half-body wall (i.e., the left half-body (10-5-L) and / or the right half-body (10-5-R)).
[0132] At this point, the half-body wall portion (left half-body portion (10-5-L) and / or right half-body portion (10-5-R)) includes:
[0133] The engagement hole (H1) is formed by opening in the height direction (Z direction) and length direction (X direction) of the connector (10); and
[0134] The first engaging post (C1) partially closes the engaging hole (H1) along the length direction (X direction) of the connector (10).
[0135] Furthermore, the body wall portion (shell end (10-5-E)) includes:
[0136] The second locking post (C2) protrudes along the length direction (X direction) of the connector (10);
[0137] The third locking post (C3) extends from the second locking post (C2) in the height direction (Z direction).
[0138] Furthermore, the second engaging post (C2) and the third engaging post (C3) of the main body wall (shell end (10-5-E)) are located at the engaging hole (H1) of the half-body wall (left half-body (10-5-L) and / or right half-body (10-5-R)).
[0139] As observed Figure 3 and Figure 4 It is understood that the structure is not one in which the half-wall portion (e.g., the left half-body portion (10-5-L)) and the main body portion (the shell end portion (10-5-E)) are manufactured separately and then joined together. This is because even if they were to be manufactured separately and their posts (C1, C2, C3) were to be fitted together, they could not be fitted together through the engagement hole (H1) (i.e., since both parts are entirely ring-shaped, they cannot be separated and fitted together after manufacturing). Therefore, it is preferable that the half-wall portion (10-5-H) (the left half-body portion (10-5-L) and / or the right half-body portion (10-5-R)) is formed using a first insert molding (first injection molding) and the main body portion (the shell end portion (10-5-E)) is formed using a second insert molding (second injection molding).
[0140] Figure 4 The second locking post (C2) and the third locking post (C3) and Figure 3 The first locking post (C1) is connected.
[0141] The first engaging post (C1) is shaped to intersect the extending directions of the second engaging post (C2) and the third engaging post (C3). Specifically, the first engaging post (C1) extends in the Y direction, the second engaging post (C2) extends in the X direction, and the third engaging post (C3) extends in the Z direction, with the Y direction intersecting both the X and Z directions. That is, the internal engaging shape causes the resin posts to intersect in the X-axis / Y-axis directions.
[0142] Moreover, such as Figure 4 As shown, the body wall (housing end (10-5-E)) also includes a fourth engaging post (C4) protruding in the length direction of the connector (10), and the fourth engaging post (C4) is connected to the third engaging post (C3) in the length direction (X direction) of the connector (10).
[0143] in addition, Figure 4 The fourth card joint column (C4) and Figure 3 The first locking post (C1) is connected.
[0144] This structure allows for the joining of two structures. Figure 3 The middle image shows the left half of the body (10-5-L) and in Figure 4 The middle diagram shows the shell end (10-5-E) and illustrates their assembly, but the right half (10-5-R) is also assembled to the shell end (10-5-E) in the same manner. Furthermore, for convenience, the shell end (10-5-E) is... Figure 4 Only one side is shown in the figure, but the two sides of the end of the housing (10-5-E) are joined in the same way.
[0145] That is, as in Figure 2 As can be seen from what we see, this combination appears in roughly four places. Figure 2 Based on this, the four locations are the left side of the left half (10-5-L) and the shell end (10-5-E), the right side of the left half (10-5-L) and the shell end (10-5-E), the left side of the right half (10-5-R) and the shell end (10-5-E), and the right side of the right half (10-5-R) and the shell end (10-5-E).
[0146] In addition, Figure 3 and Figure 4 In the example, the case in which there is a locking hole (H1) and a first locking post (C1) in the left half (10-5-L) (i.e., the half wall) and a second locking post (C2), a third locking post (C3) and a fourth locking post (C4) in the end of the housing (10-5-E) (i.e., the body wall) is described, but it is not necessary to be limited to this.
[0147] For example, conversely, it can also be Figure 3 The engaging hole (H1) and the first engaging post (C1) shown in the diagram are located at the end of the housing (10-5-E) (i.e., the body wall). Figure 4 The second locking post (C2), the third locking post (C3), and the fourth locking post (C4) shown in the figure are located in the left half (10-5-L) and / or the right half (10-5-R) (i.e., the half-body wall portion).
[0148] Figure 5 Will Figure 3 The half-body wall portion (10-5-H) shown (especially the left half-body portion (10-5-L)) is slightly reoriented and re-illustrated.
[0149] Figure 6 The diagram shows Figure 2 Part of the body wall (10-5-E) (shell end) shown.
[0150] This utility model relates to a connector (10) formed by the following (see reference). Figure 5 and Figure 6): Half-body wall portion (10-5-H) (i.e., left half-body portion (10-5-L) and / or right half-body portion (10-5-R)), for multiple signal terminals (10-3) to be arranged in the length direction (X direction) of connector (10);
[0151] The main body wall (i.e., the shell end (10-5-E)) is connected to both ends of the half-body wall (10-5-H) (left half-body (10-5-L) and / or right half-body (10-5-R)).
[0152] Reference Figure 5 The half-wall portion (10-5-H) has a skirt portion (SK) extending from the wall portion (e.g., the first wall portion (10-5-W1)) and a column portion (CC) (joint column) protruding to the upper surface of the skirt portion (SK).
[0153] On the other hand, refer to Figure 6 The body wall portion (10-5-E) (i.e., the shell end) has a base (10-5-B) extending from the wall portion (e.g., the fourth wall portion (10-5-W4)).
[0154] A portion of the base (10-5-B) covers a portion of the skirt (SK) of the half-wall portion (10-5-H) and connects with the column portion (CC) (joining column). This column portion (CC) is related to the engaging shape of the lower end face (lower end portion).
[0155] The posts (CC) are formed at both ends of the signal terminals (10-3). That is, in Figure 5 Only one column (CC) at one end of the half-wall (10-5-H) is shown in the figure, but a column (CC) also exists at the other end (not shown) of the half-wall (10-5-H) shown in the figure.
[0156] It is preferable that the half-body wall (10-5-H) is formed by first insert molding (first injection molding) and the body wall (10-5-E) is formed by second insert molding (second injection molding).
[0157] Although not limited to this, but Figures 5 to 6 In this example, the upper surface of the column (CC) is exposed. That is, Figure 5 The column (CC) and Figure 6 The bonding column hole (CCH) matches, at which point the upper surface of the column (CC) is not covered by resin but exposed.
[0158] On the other hand, although Figure 5 and Figure 6The embodiment is characterized by a column portion (CC) (joining column) on the half-body wall portion (10-5-H) side and a joining column hole (CCH) on the main body wall portion (10-5-E) side, but it is not limited to this. On the contrary, it is also possible to have a joining column hole (CCH) on the half-body wall portion (10-5-H) side and a column portion (CC) (joining column) on the main body wall portion (10-5-E) side.
[0159] Figure 7 Observing from a slightly different angle Figure 4 The body wall portion (10-5-E) shown (shell end).
[0160] Reference Figure 3 and Figure 7 The following explains the connection relationships between the components.
[0161] This utility model relates to a connector (10) formed from the following:
[0162] The half-body wall (10-5-H) provides space for multiple signal terminals (10-3) to be arranged along the length (X direction) of the connector (10).
[0163] The main body wall (10-5-E) is connected to both ends of the half-body wall (10-5-H).
[0164] At this time, the half-body wall portion (10-5-H) has an engagement groove (G1) formed recessed at one end in the longitudinal direction (X direction) of the connector (10) (see reference). Figure 3 The engagement slot (G1)).
[0165] Furthermore, the body wall portion (10-5-E) has an engaging portion (P1) that protrudes at one end in the longitudinal direction (X direction) of the connector (10) (see reference). Figure 7 The engaging part (P1)).
[0166] For reference, Figure 4 The diagram shows part of the fourth locking post (C4) and its connection to the center. Figure 7 The diagram shows that the engaging portions (P1) are arranged side-by-side with each other in the width direction (Y direction) of the connector (10), and Figure 4 The fourth card joint column (C4) and Figure 4 and Figure 7 The engaging parts (P1) can be joined together or slightly separated. Figure 4 and Figure 7 The diagram shows an example in which at least a portion of the fourth engaging post (C4) and the engaging part (P1) are connected to each other in the width direction (Y direction) of the connector (10).
[0167] Right now, Figure 7The engaging part (P1) of the body wall (10-5-E) is located Figure 3 The engaging groove (G1) of the half-body wall (10-5-H), and as Figure 7 As shown, the engaging portion (P1) has a root portion, and the vertical length (D2) of any other portion of the connector (10) that is farthest from the root portion in the longitudinal direction is set to be longer than the vertical length (D1) of the root portion. This structure is related to the engaging shape of the side portion.
[0168] exist Figure 7 In the example, any other part (non-root portion, represented by D1 in the vertical length diagram) relative to the root portion (the part with D2 in the vertical length diagram) is the terminal portion, but it is not necessarily limited to this terminal portion. That is, since the reason for making D1 and D2 (but D2 is longer than D1) different is to firmly fix the half-body wall portion (10-5-H) and the main body wall portion (10-5-E), when the case of D2>D1 is taken as a premise, the portion of length D2 (non-root portion) does not necessarily need to be the terminal portion. Figure 7 (The left end of the middle), as long as it is any part on the left side starting from the root.
[0169] The half-wall portion (10-5-H) is formed by first insert molding (first injection molding), and the main body wall portion (10-5-E) is formed by second insert molding (second injection molding).
[0170] Moreover, the side of the engaging part (P1) is exposed on the surface of the connector (10).
[0171] On the other hand, Figure 3 and Figure 7 The figure shows an engaging groove (G1) in the half-body wall portion (10-5-H). Figure 3 In the case where the body wall (10-5-E) has an engaging portion (P1), Figure 7 ),
[0172] However, it is not necessary to limit it to this. As an example, the opposite could be that the half-body wall (10-5-H) has an engaging part (P1) and the main body wall (10-5-E) has an engaging groove (G1).
[0173] Figure 8 yes Figure 1 The top surface of the plug connector (10) shown is illustrated.
[0174] Figure 9 yes Figure 1 and Figure 8 The bottom surface of the plug connector (10) shown is illustrated.
[0175] Figure 10 yes Figure 1 , Figure 8 , Figure 9 Partial side view of the plug connector (10) shown.
[0176] Refer to together Figures 8 to 10 The following describes one feature of this utility model.
[0177] exist Figure 8 The middle figure shows the power terminal (10-1), signal terminal (10-3), signal terminal mounting part (10-3-M), half-body wall part (10-5-H), main body wall part (10-5-E), and main body wall connecting part (10-5-EC) as described above.
[0178] exist Figures 8 to 10 The examples of single-injection and double-injection molding shown in the illustrations remain unchanged, but the various features of this utility model are intended to be improved through... Figures 8 to 10 One feature of this utility model is not significantly related to whether it involves primary or secondary injection molding, but rather focuses on the height of the components (power terminal (10-1) and housing (10-5)). This will be explained below.
[0179] Figure 9 It is viewed from the opposite side of the Z direction. Figure 8 That is, if Figure 8 It is the upper surface pattern Figure 9 This is the bottom surface view (bottom surface view).
[0180] exist Figure 9 The dotted line in the middle represents the part where the transport track (not shown) connects to the plug connector (10), namely the transport track grounding part (TRC).
[0181] The plug connector (10) has:
[0182] The shell (10-5) includes side walls (10-5-W1, 10-5-W3), end walls (10-5-W2, 10-5-W4), and a base (10-5-B);
[0183] Power terminal (10-1) (fittings), mounted on end wall (10-5-W2, 10-5-W4);
[0184] The signal terminal (10-3) has a contact portion (in contact with a mating connector (jack connector) not shown) and a mounting portion (10-3-M), and is arranged on each side wall (10-5-W1, 10-5-W3).
[0185] Moreover, such as Figure 10As shown, at least a portion of the lowermost end face of the power terminal (10-1) (e.g., the mounting portion of the power terminal (10-1-M)) is located at a position higher than the lowermost end face (10-5-BL) of the base (10-5-B) of the housing (10-5).
[0186] At least a portion of the lowermost end face of the power terminal (10-1) (e.g., the mounting portion of the power terminal (10-1-M)) is located at a position higher than the lowermost end face (10-5-BL) of the base bottom (10-5-B) of the housing (10-5), and is the portion that repeats the end wall (10-5-W2, 10-5-W4) in the length direction (X direction) of the connector (10).
[0187] On the other hand, at least a portion of the lowermost end face of the power terminal (10-1) (e.g., the mounting portion (10-1-M) of the power terminal) is located at a position higher than the lowermost end face (10-5-BL) of the base (10-5-B) of the housing (10-5), and is a portion that does not overlap with the mounting portion (10-3-M) of the signal terminal (10-3) in the length direction (X direction) of the connector (10).
[0188] The signal terminals (10-3) of the sidewalls (10-5-W1, 10-5-W3) are arranged alternately along the length (X direction) of the connector (10), therefore, the mounting portions (10-3-M) of the signal terminals (10-3) exist in two directions of the sidewalls (10-5-W1, 10-5-W3). That is, observe Figure 8 It can be seen that, taking the first wall portion (10-5-W1) as a reference, the mounting portion (10-3-M) is located on the outer side of the first wall portion (10-5-W1). Figure 8 The left side of the middle section protrudes once and is inside the first wall portion (10-5-W1). Figure 8 The lower middle side protrudes once, and then repeats in the same way thereafter.
[0189] Furthermore, at least a portion of the mounting portion (10-1-M) of the power terminal (10-1) (or the lowermost end face of the power terminal (10-1)) is located at a position higher than the lowermost end face of the base (10-5-B) of the housing (10-5), and has a portion that repeats between the mounting portions (10-3-M) in both directions of the connector (10) along the length direction (X direction) and the mounting portions (10-3-M) of the sidewalls (10-5-W1, 10-5-W3). This is achieved through... Figure 9 Further explanation is needed, which means that for at least... Figure 9 The portion corresponding to the grounding section (TRC) of the conveyor track shown should meet the following requirements. Figure 10The relationship shown is (i.e., there is a height difference H). Specifically, "between the mounting portions (10-3-M) in two directions of the sidewalls (10-5-W1, 10-5-W3) along the length direction (X direction) of the connector (10)" refers to... Figure 9 The part corresponding to the grounding section (TRC) of the transport track shown in the diagram.
[0190] like Figure 9 As shown, the reason for setting the grounding part (TRC) of the transport track is that it is located on the bottom surface of the resin, compared to the mounting part (10-1-M) of the power terminal (10-1). Figure 10 The structure below the 10-5-BL ensures the guide path portion in the four-column stretch structure (deep stretch structure) so that the metal surface (i.e., the power terminal (10-1) of the connector (10)) is not sheared off during the transfer of the connector (10). To this end, it is necessary to ensure the step difference between the power terminal mounting surface (10-1-M) and the mold (housing (10-5)). In summary, the transfer track grounding portion (TRC) is a step structure to prevent contact with the transfer track (not shown).
[0191] For reference, the term "four columns" refers to the case where the signal terminals (10-3) are arranged in a zigzag pattern on the first wall portion (10-5-W1) as two columns (i.e., the mounting portion is not one column but two columns), and the case where the signal terminals (10-3) are arranged in a zigzag pattern on the third wall portion (10-5-W3) as another two columns (i.e., the mounting portion is not one column but two columns), thus representing a total of four columns.
[0192] Figure 11 It is Figure 1 A portion of the plug connector (10) is shown in magnification.
[0193] Figure 12 Is it changing the angle? Figure 11 A portion of it is shown in enlarged form.
[0194] Among the various features of this utility model, it is intended to be achieved through Figure 11 , Figure 12 The features of this utility model are described below.
[0195] The plug connector (10) of this utility model includes:
[0196] The shell (10-5) includes side walls (10-5-W1, 10-5-W3) and end walls (10-5-W2, 10-5-W4), a base (10-5-B), and a skirt (SK) extending in the width direction from the side walls;
[0197] Power terminals (10-1) are mounted on the end walls (10-5-W2, 10-5-W4);
[0198] Signal terminals (10-3) span and are installed across and on each side wall (10-5-W1, 10-5-W3) and skirt (SK).
[0199] At this time, the signal terminal (10-3) includes a mounting part (10-3-M), a contact part (10-3-C), and a tail part (10-3-E).
[0200] The upper surface of the tail (10-3-E) is exposed above the skirt (SK), and at least a portion of it that connects with the skirt (SK) is higher than the upper surface of the skirt (SK) (see reference). Figure 12 wait).
[0201] Furthermore, the two parts that meet in the length direction (X direction) are positioned higher than the upper surface of the skirt (SK), and the part that meets in the width direction (Y direction) is on the same surface. (See reference...) Figure 12 This can be seen from the fact that the tail (10-3-E) bulges upward compared to the upper surface of the skirt (SK), which extends outward in the width direction of the connector (10) as part of the housing (10-5). More precisely, it can be seen that the tail (10-3-E) is higher than the skirt (SK) in the left and right (X direction) directions, while the height of the tail (10-3-E) is the same as the height of the skirt (SK) in the width direction (Y direction).
[0202] To further explain, the reason why the upper surface of the tail (10-3-E) is preferably exposed is for probe inspection. Moreover, the reason why the height difference is preferred is that when the probe approaches and contacts from above for inspection, if it is on the same surface (at the same height), it is difficult to distinguish and / or easy to contact both the metal part and the mold part.
[0203] Furthermore, the distal end face of the tail (10-3-E) is not exposed. For example... Figure 12 As seen in the image, the end face of the tail (10-3-E) (in the width direction (+Y direction) of the connector) is blocked by resin as part of the housing (10-5) (i.e., not exposed).
[0204] The reason for adopting this configuration is referred to Figure 13 To illustrate.
[0205] Figure 13 This is a comparative example used to illustrate a feature of this utility model.
[0206] The reason is that, assuming the end face (e.g., copper material) of the assumed tail (10-3-E) is exposed during observation. Figure 13 (Comparative example) In the case of Figure 13During the soldering process of the mounting part (10-3-M`), etc., there are Figure 13 The mounting section (10-3-M`) and Figure 13 There is a concern that the connector may be discarded due to a short circuit at the tail (10-3-E`). In particular, given the current miniaturization of connectors, this concern about short circuits cannot be ignored.
[0207] Moreover, even if it is not necessarily caused by welding, even if there is no problem in the welding, moisture may be present around the mounting part, which may cause a short circuit and lead to the device being discarded.
[0208] That is, because the distance between the exposed metal (copper, etc.) not being installed and the adjacent mounting parts is short, there is a risk of solder bridging or dendrite formation in high humidity environments, and this risk needs to be reduced. Figures 11 to 12 The structure of this utility model can greatly reduce, for example, Figure 13 The concern about short circuits is shown in the (comparative example).
[0209] Returning to the present invention Figure 11 , Figure 12 Please provide an explanation.
[0210] The tail (10-3-E) is not mounted to the substrate (not shown). The mounting part (10-3-M) on the opposite side of the tail (10-3-E) (in the width direction (Y direction) of the connector (10)) is mounted to the substrate (not shown).
[0211] Furthermore, the lowest end face of the tail (10-3-E) is higher than the lowest end face of the skirt (SK). This is consistent with the above description that the tail (10-3-E) is not mounted to the substrate (not shown).
[0212] In summary, Figures 11 to 12 One feature of the present invention shown is that although the upper surface of the tail (10-3-E) is exposed, the end face is not exposed, and there is also a step for probe inspection.
[0213] For example, the same principles described for the plug connector (10) may also apply to the socket connector (not shown) to the extent that they are not contradictory in nature.
[0214] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the described embodiments and can be manufactured in various different forms. Furthermore, those skilled in the art will understand that the present invention can be implemented in other specific forms without altering its technical concept or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not as limiting.
