Description

Technical Field

[0001] This utility model relates to an electrical connector. While not limited to electrical connectors, it relates to, for example, a socket connector that is combined with a mating connector, i.e., a plug 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 referred to as a jack connector. Such plug and receptacle connectors can be formed by arranging terminals in a mold section. The plug 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 into account.

[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

[0009] [The problem that the utility model aims to solve]

[0010] The technical problem to be solved by this utility model is to provide a structure that forms the connector housing through multiple injection moldings instead of a single injection molding, and that enhances the bonding force between the continuously injection molded parts in such multiple injection moldings.

[0011] Another technical problem that this invention aims to solve is to improve the strength of the connector without increasing its overall length.

[0012] In addition, it is necessary to make the connector easy to manufacture without increasing the length of the connector separately.

[0013] The technical issues of this utility model are not limited to those mentioned above, and other technical issues not mentioned can be clearly understood by those skilled in the art based on the following description.

[0014] [Technical means to solve the problem]

[0015] According to this utility model, an electrical connector is provided that is coupled to a mating connector and connected to a substrate, characterized in that the electrical connector comprises:

[0016] Metal terminals, signal terminals, housing,

[0017] The housing includes at least two half-body parts and a connecting part that connects the half-body parts to each other.

[0018] The signal terminal is provided at the half-body portion along the length of the electrical connector.

[0019] The two halves are connected to the connecting portion by a single insert molding process, forming a rectangular housing having a first wall, a second wall, a third wall, and a fourth wall. The first wall extends along the length direction of the electrical connector, the second wall extends along the width direction of the electrical connector, the third wall extends along the length direction of the electrical connector, and the fourth wall extends along the width direction of the electrical connector.

[0020] The metal terminal includes a first covering portion covering the first wall portion, a second covering portion covering the second wall portion, and a third covering portion covering the third wall portion.

[0021] A joint portion at the first cover portion is formed in the width direction of the electrical connector and is in close contact with the connecting portion.

[0022] The half-body portion is formed using the first insert molding, and the connecting portion is formed using the second insert molding after the first insert molding.

[0023] According to this utility model, an electrical connector is provided that is coupled to a mating connector and connected to a substrate, characterized in that the electrical connector comprises:

[0024] Metal terminals, signal terminals, housing,

[0025] The housing includes at least two half-body parts and a connecting part that connects the half-body parts to each other.

[0026] The signal terminal is provided at the half-body portion along the length of the electrical connector.

[0027] The two halves are connected to the connecting portion by a single insert molding process, forming a rectangular housing having a first wall, a second wall, a third wall, and a fourth wall. The first wall extends along the length direction of the electrical connector, the second wall extends along the width direction of the electrical connector, the third wall extends along the length direction of the electrical connector, and the fourth wall extends along the width direction of the electrical connector.

[0028] The metal terminal includes a first covering portion covering the first wall portion, a second covering portion covering the second wall portion, and a third covering portion covering the third wall portion.

[0029] A joint portion at the second cover portion is formed along the length direction of the electrical connector and is in close contact with the connecting portion.

[0030] The half-body portion is formed using the first insert molding, and the connecting portion is formed using the second insert molding after the first insert molding.

[0031] Preferably, the shape of the joint is a protruding shape, a recessed shape, a through-hole shape, or a curved shape.

[0032] Preferably, the first covering portion, the second covering portion, and the third covering portion are each formed into an inverted U-shape having an outer covering portion and an inner covering portion.

[0033] The joining portion is formed on the outer covering portion and the inner covering portion, respectively.

[0034] The outer joint portion formed on the outer cover portion and the inner joint portion formed on the inner cover portion are opposite to each other.

[0035] Preferably, one of the at least two halves is L-shaped.

[0036] Preferably, the connecting portion formed by the secondary insert molding has at the end... Shaped to allow engagement with one of the at least two halves and the metal terminal.

[0037] Preferably,

[0038] For the connecting part The ends of the shape,

[0039] Two lateral extensions extend along the length of the electrical connector. The portion of the lateral extension located outside the width direction of the electrical connector is referred to as the first extension, and the portion located inside the width direction of the electrical connector is referred to as the second extension.

[0040] An extension in the longitudinal direction extends in the width direction of the electrical connector, and when said that extension in the longitudinal direction is referred to as the third extension,

[0041] The first extension is combined with either the first wall portion or the third wall portion, which is a sidewall; the second extension is part of the central island portion; and the third extension connects the first extension and the second extension.

[0042] [Effects of the utility model]

[0043] According to this utility model, the inner joint portion 20-1-IJ not only has a protrusion ( Figure 6 The right side of 20-1-IJ also has a recessed part ( Figure 6 (The left side of 20-1-IJ). It can be confirmed that the resin constituting the connecting portion 20-5-C is filled in such a recess. That is, since resin 20-5-C is injected into the recess of the inner connecting portion 20-1-IJ during secondary insert molding, the bonding force between the connecting portion 20-5-C (part of the housing 20-5) and the metal 20-1 is further enhanced compared to the case without the corresponding recess.

[0044] In particular, in this invention, since the primary insert molding (half-body portion 20-5-H, which is part of the housing 20-5) and the secondary insert molding (connecting portion 20-5-C, which is part of the housing 20-5) are performed separately and sequentially, the rigidity and inherent bonding strength of the housing 20-5 itself (formed by combining multiple components) or the bonding strength between the housing 20-5 (especially the connecting portion 20-5-C) and the metal 20-1 are more important than in the case where the housing is formed as a whole from a single resin component. Because the primary and secondary insert molding processes are separated, the shape freedom of the housing 20-5 becomes higher, and the shape freedom of the metal 20-1 or signal terminal 20-3 also becomes higher. However, conversely, there may be some loss in the durability of the housing 20-5 itself or the bonding strength between the housing 20-5 and the metal 20-1, etc. However, this utility model, through the recessed / protruding (projecting) structure of the inner joint 20-1-IJ and the connecting part 20-5-C as described above, has the effect of compensating for the insufficient durability of the housing 20-5 itself or the insufficient bonding strength between the housing 20-5 and the metal 20-1, etc. (The same applies to the outer joint 20-1-OJ, which will be described below). That is, the inner joint 20-1-IJ (or the outer joint 20-1-OJ) of this utility model is particularly useful when the housing 20-5 is formed by primary insert molding and secondary insert molding (or even more than three times).

[0045] In other words, it can be argued that a larger connector size would have been required to achieve the same bonding strength ("rigidity within the housing" or "bonding strength between the housing (whole or part) and the metal"), but can now be manufactured smaller. In particular, the same level of bonding strength ("rigidity within the housing" or "bonding strength between the housing (whole or part) and the metal") can be achieved while shortening the connector's length (rather than its width).

[0046] Additionally, if necessary, the protrusion of the inner mating portion 20-1-IJ can further enhance the fitting force (adhesion force) with the mating connector (not shown).

[0047] Similarly, the outer joint 20-1-OJ not only has a protrusion ( Figure 6 The right side of the 20-1-OJ also has a recessed part ( Figure 6 (The left side of 20-1-OJ). It can be confirmed that such a protrusion enters and engages with the resin constituting the connecting part 20-5-C. That is, since the protrusion of the outer connecting part 20-1-OJ enters and engages with the resin 20-5-C during the secondary insert molding, the bonding force between the connecting part 20-5-C (part of the housing 20-5) and the metal 20-1 is further enhanced compared to the case without the corresponding protrusion.

[0048] Although not targeted Figure 5 The inner joint 20-1-IK shown (inside the second cover 20-1-C2) Figure 5 (In the example, there are 2 locations) which will be described in detail, but the inner joint 20-1-IK also follows the same principle. Figure 6 The inner joint 20-1-IJ shown has a recessed / protruding structure with a similar cross-section. Similarly, by inserting the connecting part 20-5-C into the recess of the inner joint 20-1-IJ, the bonding force between the housing 20-5 (especially the connecting part 20-5-C) and the metal 20-1 is improved.

[0049] exist Figures 7a to 7g In the first variation, through

[0050] (i) The recessed structure of the connecting part 20-5-C (correspondingly, the protruding structure of the outer connecting part 20-1-OJ of the metal 20-1).

[0051] (ii) The protruding structure of the connecting part 20-5-C (correspondingly, the recessed structure of the inner connecting part 20-1-IJ of the metal 20-1).

[0052] (iii) The structure of the narrow portion 20-5-CN of the connecting portion 20-5-C (correspondingly, the structure of the half-body portion 20-5-H filling the corresponding narrow portion 20-5-CN) Figure 7c (The structure shown by the dashed quadrilateral)

[0053] This results in improved rigidity or bonding strength within the housing 20-5 and / or between the housing 20-5 and the metal 20-1.

[0054] It can be seen that the second variation ( Figures 8a to 8g ) does not have the first variant example ( Figures 7a to 7g The second variation possesses "the additional bonding force obtained by wrapping the narrow portion 20-5-CN with the half-body portion 20-5-H". Conversely, since the shapes of the connecting portion 20-5-C and the half-body portion 20-5-H are simpler in the second variation, they are easier to manufacture. For example, it can be considered that the physical properties of the resin used in manufacturing the connecting portion 20-5-C or the half-body portion 20-5-H, or the manufacturing time, are less restricted compared to the first variation.

[0055] The advantage of the third variation is that, compared to the case in the second variation where fine-tuning force was originally required to create the protruding / recessed structure of the outer joint 20-1-OJ of the metal 20-1, it is easier to manufacture the perforation (i.e., the groove 20-1-OJ) that does not require fine-tuning force.

[0056] In the fourth variation, the connecting portion 20-5-C is embedded in the groove 20-1-J itself, the outer side of the groove 20-1-J (in the width direction of the connector 20), and the inner side of the groove 20-1-J (in the width direction of the connector 20). Compared with the third variation, this can be seen as a factor that can further improve the bonding strength.

[0057] The effects of this utility model are not limited to the examples above, and more diverse effects are included in this specification. Attached Figure Description

[0103] The advantages and features of this invention, as well as the methods of achieving them, 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.

[0104] Figure 1 This is a perspective view of an example of the socket connector 20 in the electrical connector according to the present invention.

[0105] In this specification, the term "electrical connector" may be used as a plug connector (not shown), or as a jack connector 20 (also referred to as a "socket connector"), or as both (or an assembly thereof) of a plug connector (not shown) and a jack connector 20.

[0106] exist Figure 1 The example shown includes a metal 20-1 (also called a metal terminal), a signal terminal 20-3, an auxiliary terminal 20-4, and a housing 20-5 (mold part) of a socket connector 20. However, it is not limited to this, but... Figure 1 In the example, metal 20-1 can also be used as power terminal 20-1.

[0107] Metal 20-1 is a metal structure used to supplement the strength of connector 20. Power terminal 20-1 allows for input and output of power signals. As described above, in Figure 1In this example, metal 20-1 can also serve as a power terminal. However, this invention does not preclude metal 20-1 from being formed separately from the power terminal (for example, auxiliary terminal 20-4 alone can also be a power terminal).

[0108] Signal terminal 20-3 can input and output data signals.

[0109] Figure 1 The auxiliary terminal 20-4 shown can function as a power supply terminal and also as a signal terminal.

[0110] Therefore, in Figure 1 In the example,

[0111] Only metal 20-1 can function as a power supply terminal.

[0112] Metal terminal 20-1 does not function as a power supply terminal; only auxiliary terminal 20-4 can function as a power supply terminal.

[0113] -Metal 20-1 and auxiliary terminal 20-4 can also work together as power terminals.

[0114] Alternatively, for example, signal terminal 20-3 can also consist of four pins that allow a current of 0.3 A, and can function as a power supply terminal by allowing a current exceeding 0.3 A, such as 5 A. However, having four pins is just one example. For reference, in Figure 1 In the example, there are 68 signal terminals 20-3.

[0115] The housing 20-5 has a base 20-5-B. The housing 20-5 has a wall portion protruding from the upper surface of the base 20-5-B, and metal 20-1 (which may also serve as a power terminal), signal terminal 20-3, auxiliary terminal 20-4, etc. are formed on the wall portion.

[0116] The wall is generally formed by four parts, including the first wall part 20-5-W1, the second wall part 20-5-W2, the third wall part 20-5-W3, and the fourth wall part 20-5-W4. For example... Figure 1 As shown, it can be observed that the wall portion 20-5-W1 is connected in the order of first wall portion 20-5-W2, second wall portion 20-5-W4, and third wall portion 20-5-W3, with the third wall portion 20-5-W3 again connected to the first wall portion 20-5-W1. Figure 1 In the middle, the connector 20 is roughly rectangular, with the first wall portion 20-5-W1 and the third wall portion 20-5-W3 as side walls, and the second wall portion 20-5-W2 and the fourth wall portion 20-5-W4 as end walls.

[0117] The housing 20-5 (molding part) of the socket connector 20 is preferably made of plastic, such as liquid crystal polymer (LCP). Alternatively, the housing 20-5 may be formed of an insulator including resin and epoxy resin, but is not limited thereto. The metal 20-1, signal terminal 20-3, and auxiliary terminal 20-4 of the socket connector 20 are preferably made of metal, although not limited thereto; for example, copper may be used, and the copper alloy may be gold-plated (with a nickel underlayer).

[0118] When viewed with reference to a sidewall (e.g., the third wall portion 20-5-W3), it can be seen that the signal terminals 20-3 are arranged in two different ways (as an example, signal terminals 20-3 of the same shape of the same type are arranged in two different ways by only changing their orientation). That is, although not limited to this, Figure 1 The signal terminals 20-3 are arranged alternately along the length (X direction) of the connector 20, such that the mounting portion 20-3-M is located once on the outside of the connector width direction and once on the inside of the connector width direction (visible through the through hole 20-5-PH (also called the "inspection window")) (see reference). Figure 3 Furthermore, among the plurality of mounting portions 20-3-M located inside the connector 20 in the width direction (Y direction), the mounting portion 20-3-M of the signal terminal 20-3 provided on the third wall portion 20-5-W3 and the mounting portion 20-3-M of the signal terminal 20-3 provided on the first wall portion 20-5-W1 are arranged in a zigzag pattern (this also refers to...). Figure 3 Therefore, since the pitch of signal terminal 20-3 is not necessarily equal to the mounting pitch (the mounting pitch is approximately twice the pitch of signal terminal 20-3), many signal terminals 20-3 can be placed in a narrow space.

[0119] Figure 1 The label indicates a housing 20-5 (socket housing), but the housing 20-5 includes, for example, three parts: a half-body portion 20-5-H (referred to as 20-5-H1 when distinguished from the other side), a half-body portion 20-5-H (referred to as 20-5-H2 when distinguished from one side), and a connecting portion 20-5-C (described below). The half-body portion 20-5-H1 and the half-body portion 20-5-H2 are also referred to as half-body portion 20-5-H when there is no need to distinguish them. Half-body portion 20-5-H sometimes refers only to one of the half-body portions on one side / the other side, and sometimes both are referred to collectively. These structures will be discussed below. Figure 2 This will be explained in detail later.

[0120] Furthermore, the central island portion 20-5-I refers to the portion that rises upwards from the center of the connector 20.

[0121] Figure 2This indicates the half-body portion 20-5-H on one side.

[0122] When there is no need to distinguish between the two halves 20-5-H1 and 20-5-H2, they are also referred to as halves 20-5-H.

[0123] exist Figure 2 The image shows a state where the metal 20-1 in connector 20 is omitted and a signal terminal 20-3 is provided on one half-body 20-5-H. This does not indicate the manufacturing sequence, but is shown for ease of explanation of the structure.

[0124] Right now, Figure 2 The half-body portion 20-5-H (i.e., 20-5-H1) shown is approximately... The shape is that of a character, and it has a first wall part 20-5-W1 and a second wall part 20-5-W2.

[0125] exist Figure 2 Not shown in the diagram, but the other half, 20-5-H (i.e., 20-5-H2), is roughly shaped like... It has an L-shaped shape and a third wall portion 20-5-W3 and a fourth wall portion 20-5-W4.

[0126] The mounting portions 20-3-M of the signal terminals 20-3 are arranged alternately in a zigzag pattern, one on the outer side and one on the inner side, in the width direction of the connector 20.

[0127] Figure 3 This indicates the connecting part 20-5-C.

[0128] While not limited to this, the connecting part 20-5-C can be formed as an integral part (as...). Figure 3 The resin part shown is a component of a structure, such as... Figure 3 As shown.

[0129] That is, it can be regarded as (i) Figure 2 The approximate shape shown The half of the character shape, 20-5-H1.

[0130] (ii) Figure 2 Not shown in the image, but roughly in the shape of The other half of the character shape is 20-5-H2.

[0131] (iii) Figure 3 The connecting part 20-5-C shown is combined to form the housing 20-5.

[0132] In (iii), it can be considered that the connecting portion 20-5-C includes at the end. The shape. Specifically... Figure 3 The right side of the middle The shape (the right side portion of the entire connecting part 20-5-C) and the first half-body part 20-5-H1 (i.e., Figure 2 The half-body portion 20-5-H1 shown on one side) and Figure 1 The metal 20-1 on the right side is bonded. Figure 3 The middle left side appears The shape (the left side of the entire connecting part 20-5-C) and the second half of the body 20-5-H2 (i.e., with) Figure 2 The half-body portion 20-5-H1 shown corresponds to the other half-body portion 20-5-H2 (not shown) and Figure 1 The metal on the left side is 20-1 combined.

[0133] Figure 4 Indicates and Figure 3 The connecting part 20-5-C has a slightly different shape.

[0134] exist Figure 3 The diagram illustrates the case where the connecting part 20-5-C is a single component, but... Figure 4 The text is not limited to this, indicating that the connecting part 20-5-C can also be made of three components.

[0135] That is, in Figure 4 China (and) Figure 3 (The situations differ), as shown in the following examples:

[0136] (i) The first connecting part 20-5-C1 on the right (a part of the connecting part 20-5-C).

[0137] (ii) The second connecting part 20-5-C2 on the left (a part of the connecting part 20-5-C).

[0138] (iii) A third connecting part (not shown) (part of connecting part 20-5-C, connecting the first connecting part 20-5-C1 and the second connecting part 20-5-C2, the shape of which can be determined by...) Figure 3 The three components (inferred) are combined to form the connecting part 20-5-C.

[0139] The term (i) can also be considered as approximately shape.

[0140] Of course, (ii) can also be considered as approximate. shape.

[0141] Although Figure 3 Also available Figure 4 That's also possible, but Figure 3 In this case, connector 20 is formed using secondary insert molding. Figure 4In this case, connector 20 requires three insert molding processes to form, therefore, it is preferable to use... Figure 3 The situation.

[0145] (ii) The half-body portion 20-5-H1 on one side and the half-body portion 20-5-H2 on the other side are manufactured by first insert molding (also known as one-time insert molding, one-time molding, first molding).

[0146] (iii) After that, the connecting part 20-5-C is manufactured by second insert molding (also known as secondary insert molding, secondary molding, or second molding).

[0147] Thus, a connector 20 is manufactured having a metal 20-1, a signal terminal 20-3, and (if an auxiliary terminal 20-4 is required) a housing 20-5 (i.e., 20-5-H1, 20-5-H2, 20-5-C).

[0148] Next, in such Figure 4 In the form shown,

[0149] (i) Metal 20-1, signal terminal 20-3 and auxiliary terminal 20-4 are positioned by a carrier (not shown) (auxiliary terminal 20-4 may be absent depending on the situation).

[0150] (ii) The half-body portion 20-5-H1 on one side and the half-body portion 20-5-H2 on the other side are manufactured by first insert molding (also known as one-time insert molding, one-time molding, first molding).

[0151] (iii) After the first insert is formed, the first connecting part 20-5-C1 and the second connecting part 20-5-C2 are manufactured by the second insert forming (also known as secondary insert forming, secondary molding, or second molding).

[0152] (iv) After the second insert is formed, the third connector (not shown) is manufactured by the third insert forming (also known as the third insert forming, the third molding, or the third molding).

[0153] Thus, a connector 20 is manufactured having a metal 20-1, a signal terminal 20-3, and (if an auxiliary terminal 20-4 is required) a housing 20-5 (i.e., 20-5-H1, 20-5-H2, 20-5-C).

[0154] Although Figure 3 situation, Figure 4 Both are acceptable, but for ease of manufacturing, the preferred option is... Figure 3 The situation.

[0155] exist Figure 3 China and in Figure 4 In the middle, the end of the connecting part 20-5-C has shape.

[0156] The end of the connecting part 20-5-C has The meaning of shape is,

[0157] (i) may also mean having at the right end Shape and has at the left end A component shaped like a single resin block (i.e., where the connecting part 20-5-C is integral), such as Figure 3 As shown,

[0158] (ii) may also mean having at the right end A separate part of shape 20-5-C1 and having at the left end Another separate component 20-5-C2, a component consisting of two or more resin blocks (i.e., where the connecting part 20-5-C is not integral), such as Figure 4 As shown.

[0159] That is, regardless of as stated in (i) Figure 3 Is the connecting part 20-5-C a single piece or as described in (ii)? Figure 4 The connecting part 20-5-C is not a single piece; the ends of the connecting part 20-5-C each have... shape.

[0160] At this time, In the shape, two lateral extensions extend along the length of the connector 20, connecting this... Of the two extensions in the transverse direction of the shape, the portion located outside the width direction of the connector 20 is called the first extension, and the portion located inside the width direction of the connector 20 is called the second extension.

[0161] exist In the shape, one longitudinal extension extends in the width direction of the connector 20, and when said longitudinal extension is referred to as the third extension,

[0162] The first extension is combined with the side wall, namely the first wall portion 20-5-W1 or the third wall portion 20-5-W3, the second extension is part of the central island portion 20-5-I, and obviously the third extension connects the first extension and the second extension.

[0163] Figure 5 yes Figure 1 A magnified view of a portion of the image.

[0164] Although Figure 1 Most of the components shown are presented as is, but the focus will be further on metal 20-1.

[0165] Observe metal 20-1, it has

[0166] - The first covering portion 20-1-C1 that covers the end portion of the first wall portion 20-5-W1,

[0167] - The second covering portion 20-1-C2 covering the second wall portion 20-5-W2,

[0168] - The third covering part 20-1-C3 that covers the end portion of the third wall part 20-5-W3,

[0169] - The bottom 20-1-B forms the base surface.

[0170] - Island covering section 20-1-I, which covers the end portion of the central island section 20-5-I.

[0171] Furthermore, an inner joining portion 20-1-IJ (also referred to as 20-1-IJ1 when distinguishing it from the joining portion of the third covering portion 20-1-C3) exists on the inner side of the first covering portion 20-1-C1. Figure 5 (In the example, there is 1 instance).

[0172] An inner joint 20-1-IK also exists on the inner side of the second cover 20-1-C2 (in... Figure 5 There are two examples).

[0173] On the inner side of the third covering part 20-1-C3 (although not visible from the angle), there is an inner joining part 20-1-IJ at a position corresponding to the inner joining part 20-1-IJ of the first covering part 20-1-C1 (also referred to as 20-1-IJ3 when distinguishing it from the joining part of the first covering part 20-1-C1 (see reference)). Figure 6 ))(exist Figure 5 (In the example, there is 1 instance).

[0174] On the outer side of the third covering part 20-1-C3, there is an outer joint part 20-1-OJ (in Figure 5(In the example, there is 1 instance).

[0175] Figure 6 For along Figure 5 The side profile shown is taken from line AA'.

[0176] Figure 5 The presence of line AA' indicates a side profile taken along line AA', as shown in the image. Figure 6 As shown.

[0177] Figure 6 The range shown is not the full width of connector 20, but only represents the third cover portion 20-1-C3 and the island cover portion 20-1-I, which are part of it.

[0178] For reference only. Figure 6 The metal 20-1 shown in the cross section is the metal 20-1 near the first wall portion 20-5-W1, the second wall portion 20-5-W2, and the third wall portion 20-5-W3 (i.e., the metal that mainly covers the second wall portion 20-5-W2), but the metal 20-1 observed from a distance is the metal on the other side (i.e., the metal 20-1 near the third wall portion 20-5-W3, the fourth wall portion 20-5-W4, and the first wall portion 20-5-W1) (i.e., the metal that mainly covers the fourth wall portion 20-5-W4).

[0179] Observing this AA' section, we can see the inner joint 20-1-IJ (more precisely, the inner joint 20-1-IJ3 of the third cover 20-1-C3) and the outer joint 20-1-OJ.

[0180] The inner joint 20-1-IJ not only has a protrusion ( Figure 6 The right side of 20-1-IJ also has a recessed part ( Figure 6 (The left side of 20-1-IJ). It can be confirmed that the resin constituting the connecting portion 20-5-C is filled in these recesses. That is, since resin 20-5-C is injected into the recesses of the inner connecting portion 20-1-IJ during secondary insert molding, the bonding force between the connecting portion 20-5-C (part of the housing 20-5) and the metal 20-1 is further enhanced compared to the case without the corresponding recesses.

[0181] In particular, in this invention, since the primary insert molding (half-body portion 20-5-H, which is part of the housing 20-5) and the secondary insert molding (connecting portion 20-5-C, which is part of the housing 20-5) are performed separately and sequentially, the rigidity and inherent bonding strength of the housing 20-5 itself (formed by combining multiple components) or the bonding strength between the housing 20-5 (especially the connecting portion 20-5-C) and the metal 20-1 are more important than in the case where the housing is formed as a whole from a single resin component. Because the primary and secondary insert molding processes are separated, the shape freedom of the housing 20-5 becomes higher, and the shape freedom of the metal 20-1 or signal terminal 20-3 also becomes higher. However, conversely, there may be some loss in the durability of the housing 20-5 itself or the bonding strength between the housing 20-5 and the metal 20-1, etc. However, this utility model, through the recessed / protruding (projecting) structure of the inner joint 20-1-IJ and the connecting part 20-5-C as described above, has the effect of compensating for the insufficient durability of the housing 20-5 itself or the insufficient bonding strength between the housing 20-5 and the metal 20-1, etc. (The same applies to the outer joint 20-1-OJ, which will be described below). That is, the inner joint 20-1-IJ (or the outer joint 20-1-OJ) of this utility model is particularly useful when the housing 20-5 is formed by primary insert molding and secondary insert molding (or even more than three times).

[0182] In other words, it can be argued that a larger connector size would have been required to achieve the same bonding strength ("rigidity within the housing" or "bonding strength between the housing (whole or part) and the metal"), but can now be manufactured smaller. In particular, the same level of bonding strength ("rigidity within the housing" or "bonding strength between the housing (whole or part) and the metal") can be achieved while shortening the connector's length (rather than its width).

[0183] Additionally, if necessary, the protrusion of the inner mating portion 20-1-IJ can further enhance the fitting force (adhesion force) with the mating connector (not shown).

[0184] Similarly, the outer joint 20-1-OJ not only has a protrusion ( Figure 6 The right side of the 20-1-OJ also has a recessed part ( Figure 6 (The left side of 20-1-OJ). It can be confirmed that such a protrusion enters and engages with the resin constituting the connecting part 20-5-C. That is, since the protrusion of the outer connecting part 20-1-OJ enters and engages with the resin 20-5-C during the secondary insert molding, the bonding force between the connecting part 20-5-C (part of the housing 20-5) and the metal 20-1 is further enhanced compared to the case without the corresponding protrusion.

[0185] For reference, Figure 6 In the cross-section, the inner joint 20-1-IJ and the outer joint 20-1-OJ are observed at the same time (that is, in the length direction of connector 20, the position of the inner joint 20-1-IJ overlaps with the position of the outer joint 20-1-OJ).

[0186] However, this invention is not limited to this, and the inner joint portion 20-1-IJ and the outer joint portion 20-1-OJ may be arranged in an alternating manner (i.e., in the longitudinal direction of the connector 20, the positions of the inner joint portion 20-1-IJ and the outer joint portion 20-1-OJ do not overlap) (for example, see below). Figures 7a to 7g ).

[0187] Although not targeted Figure 5 The inner joint 20-1-IK shown (inside the second cover 20-1-C2) Figure 5 (In the example, there are 2 locations) which will be described in detail, but the inner joint 20-1-IK also follows the same principle. Figure 6 The inner joint 20-1-IJ shown has a recessed / protruding structure with a similar cross-section. Similarly, by inserting the connecting part 20-5-C into the recess of the inner joint 20-1-IJ, the bonding force between the housing 20-5 (especially the connecting part 20-5-C) and the metal 20-1 is improved.

[0188] Figures 7a to 7g This represents the first variation of the present invention.

[0189] Figures 1 to 6 The embodiments (also known as the basic embodiments) and Figures 7a to 7g The main difference in the embodiment (also known as the first variant) lies in the position of the outer joint 20-1-OJ.

[0190] Figure 7a The location of the outer joint 20-1-OJ is shown.

[0191] Figure 7b The location of the inner joint 20-1-IJ (strictly speaking, the inner joint 20-1-IJ3 of the third cover 20-1-C3) is shown.

[0192] Figure 7c Only the connecting part 20-5-C is shown, while other parts are omitted.

[0193] Figure 7d Represented as a bottom-view 3D diagram.

[0194] Figure 7e This is a cross-sectional view viewed from above (marked with BB' and CC' lines).

[0195] Figure 7fThis is a side cross-section view along line BB'.

[0196] Figure 7g This is a side cross-sectional view along line CC'.

[0197] That is, in Figure 7a The outer joint 20-1-OJ is seen in the middle. Figure 7b The inner joint 20-1-IJ (strictly speaking, the inner joint 20-1-IJ3 of the third covering part 20-1-C3) is visible. Figures 1 to 6 In the embodiment (basic embodiment), the position of the inner joint 20-1-IJ overlaps with the position of the outer joint 20-1-OJ in the length direction of the connector 20, but unlike this, in Figures 7a to 7g In the first modified example, the positions of the inner joint 20-1-IJ and the outer joint 20-1-OJ do not overlap in the length direction of the connector 20, but are staggered.

[0198] Figure 7f It is along Figure 7e The side cross-section view taken by line BB' shows that the outer joint 20-1-OJ protrudes into the connecting part 20-5-C (from the perspective of the connecting part 20-5-C, the outer joint 20-1-OJ can be called the protrusion). This protrusion strengthens the bond between the connecting part 20-5-C and the metal 20-1.

[0199] Figure 7g It is along Figure 7e The side cross-sectional view taken by line CC' shows that a portion of the connecting part 20-5-C enters the inner joint part 20-1-IJ (from the perspective of the connecting part 20-5-C, the inner joint part 20-1-IJ can be called a recess). This recess strengthens the bonding force between the connecting part 20-5-C and the metal 20-1.

[0200] Of course, with Figure 6 Related, and similar to the above, in Figure 7g In the view of the mating connector (not shown) from the perspective of the mating connector (not the connection portion 20-5-C), the inner engagement portion 20-1-IJ of the connector 20 is a protrusion. Therefore, if necessary, the protrusion of the inner engagement portion 20-1-IJ can further enhance the fitting force (adhesion force) with the mating connector (not shown). The component of the mating connector (not shown) that engages with this protrusion can be a recessed shape or a simple planar shape, and in either case, the fitting force becomes stronger.

[0201] about Figure 7a , Figure 7c , Figure 7e Additional points to mention are Figure 7aThe dashed quadrilateral part, Figure 7c The dashed quadrilateral part and Figure 7e The dashed quadrilateral portion. This is not related to... Figures 1 to 6 The differences in the embodiments are not the same, but also apply to the same implementations. Figures 1 to 6 Part of the embodiments, Figures 1 to 6 The text does not provide sufficient explanation, therefore... Figure 7a , Figure 7c , Figure 7e The explanation is provided below.

[0202] exist Figure 7a In the middle, at the dotted quadrilateral section (not the connecting part 20-5-C), a portion of the half-body part 20-5-H can be seen.

[0203] exist Figure 7c As can be seen, the connecting portion 20-5-C does not have a uniform thickness along the length of connector 20; instead, it thins in the middle and then thickens (for reference, if the thickness were roughly the same, it would be as described below). Figure 8c (as shown)

[0204] Therefore, in Figure 7e As can be seen from the upper cross-sectional view, the outermost part of the dashed quadrilateral is the cross-section of metal 20-1, the innermost part is the half-body part 20-5-H, and the innermost part is the connecting part 20-5-C.

[0205] In this way, since the thin part of the connecting part 20-5-C (narrow part 20-5-CN) is sandwiched by the half part 20-5-H, the overall rigidity and bonding force are improved.

[0206] That is, in Figures 7a to 7g In the first variation, through

[0207] (i) The recessed structure of the connecting part 20-5-C (correspondingly, the protruding structure of the outer connecting part 20-1-OJ of the metal 20-1).

[0208] (ii) The protruding structure of the connecting part 20-5-C (correspondingly, the recessed structure of the inner connecting part 20-1-IJ of the metal 20-1).

[0209] (iii) The structure of the narrow portion 20-5-CN of the connecting portion 20-5-C (correspondingly, the structure of the half-body portion 20-5-H filling the corresponding narrow portion 20-5-CN) Figure 7c (The structure shown by the dashed quadrilateral)

[0210] This results in improved rigidity or bonding strength within the housing 20-5 and / or between the housing 20-5 and the metal 20-1.

[0211] The effects of (i) to (iii) are in Figures 1 to 6 The same applies to the basic implementation.

[0212] and Figures 1 to 6 Compared to the basic implementation, Figures 7a to 7g The first variation is even better in that the "part of the outer joint 20-1-OJ that exerts the bonding force on the connecting part 20-5-C" and the "part of the inner joint 20-1-IJ that exerts the bonding force on the connecting part 20-5-C" are distributed along the length of the connector 20, thus enabling a more uniform bonding force.

[0213] That is, in Figures 1 to 6 In the basic embodiment, the bonding force is concentrated in one place (strictly speaking, the overlapping portion in the length direction of connector 20), whereas in... Figures 7a to 7g In the first variation, the bonding force is distributed in two places (i.e., the parts that do not overlap in the length direction of the connector 20), so each has its own advantages and disadvantages and the effects are slightly different.

[0214] In short, Figures 1 to 6 In the basic embodiment, since (i) and (ii) overlap in the length direction of the connector 20, they have the effect of concentrating the bonding force in one place.

[0215] exist Figures 7a to 7g In the first variation, since (i) and (ii) do not overlap in the length direction of the connector 20, the bonding force is distributed in two places, thus achieving the effect of uniform bonding force.

[0216] This can be appropriately selected according to the required specifications or application of connector 20.

[0217] Figures 8a to 8g This represents a second variation of the present invention.

[0218] Figures 7a to 7g The embodiments (also known as the first variant) and Figures 8a to 8g The main difference between the embodiments (also known as the second variation) is whether the connecting portion 20-5-C has a narrow portion 20-5-CN.

[0219] Figures 8a to 8g and Figures 7a to 7g Most of the content corresponds, omitting explanations of similar parts and focusing primarily on the differences.

[0220] observe Figure 8c From the dashed quadrilateral portion, it can be seen that it does not have [a certain characteristic]. Figure 7c The narrow section 20-5-CN exists at the dashed quadrilateral portion. That is, with... Figure 7cThe thickness of the connecting portion 20-5-C varies, with some sections initially thinning and then thickening (i.e., the narrower section (i.e., 20-5-CN)). Figure 8c The middle part does not have such a part; within the dashed quadrilateral, the thickness of the connecting part 20-5-C is approximately the same (of course, although the part with metal 20-1 is thinner, it is still the same as...). Figure 7c The narrow section (20-5-CN) differs.

[0221] By comparison Figure 7e The dashed quadrilateral and Figure 8e This difference can also be seen in the dashed quadrilateral. That is, it can be seen that the second variation ( Figures 8a to 8g There is no first variant () Figures 7a to 7g The second variation possesses "the additional bonding force obtained by wrapping the narrow portion 20-5-CN with the half-body portion 20-5-H". Conversely, since the shapes of the connecting portion 20-5-C and the half-body portion 20-5-H are simpler in the second variation, they are easier to manufacture. For example, it can be considered that the physical properties of the resin used in manufacturing the connecting portion 20-5-C or the half-body portion 20-5-H, or the manufacturing time, are less restricted compared to the first variation.

[0222] Other than that, the situation is similar to that of the first variation.

[0223] Figures 9a to 9g This represents the third variation of the present invention.

[0224] Figures 8a to 8g The embodiments (also known as the second variation) and Figures 9a to 9g The main difference between the embodiments (also known as the third variation) is that Figure 8a The outer joint of metal 20-1, 20-1-OJ, originally protruded inwards, but... Figure 9a The middle part becomes a groove 20-1-OJ (through hole) that partially penetrates the outer wall of the metal 20-1. Figure 9a The components are also with Figure 8a The same, can be called the outer joint 20-1-OJ or the groove 20-1-OJ.

[0225] Figures 9a to 9g and Figures 8a to 8g Most of the content corresponds, omitting explanations of similar parts and focusing primarily on the differences.

[0226] observe Figure 9c It can be seen that (with) Figure 9a The groove 20-1-OJ of the metal 20-1 corresponds to the groove 20-1-OJ. A protrusion 20-5-C-OJ is formed at the connecting part 20-5-C. This protrusion 20-5-C-OJ is exposed to the outside and is... Figure 9a 3D image Figure 9fAs can be seen from the side cross-section.

[0227] The advantage of this third variation is that, compared to the case in the second variation where fine-tuning force was originally required to create the protruding / recessed structure of the outer joint 20-1-OJ of the metal 20-1, it is easier to manufacture the perforation (i.e., the groove 20-1-OJ) that does not require fine-tuning force.

[0228] Regarding the bonding force, there may be differences depending on the depth or size of the protrusion / recess structure of the outer bonding portion 20-1-OJ in the second variation, the thickness of the metal 20-1 in the third variation, or the degree to which the size of the groove 20-1-OJ is set.

[0229] Figures 10a to 10d This represents the fourth variation of the present invention.

[0230] In the fourth variation, the shape of one end half is different from that of the basic embodiment and the first to third variations.

[0231] That is, in the basic embodiment and the first to third modifications, one of the halves is " The shape of the character is " The shape is "I". In the fourth variation, the half part is two "I" shapes.

[0232] Furthermore, by examining the connecting portion 20-5-C... Figure 10a With the omitted connecting part 20-5-C Figure 10b A comparison reveals that, in the fourth variation, the connecting part 20-5-C is... Figure 10a The “ shown The shape is "", while the opposite side (illustration omitted) is "". The shape of the character "".

[0233] Observe the diagram omitting the connecting part 20-5-C. Figure 10b It can be seen that the outer side of the third cover 20-1-C3 is curved and also has a groove 20-1-J.

[0234] This curved section corresponds to groove 20-1-J. Figure 10a It cannot be seen from the center; observe its side profile, i.e. Figure 10c and Figure 10d Then it will be as follows.

[0235] exist Figure 10b The side cross-section shown is taken along line HH'. Figure 10c In the image, we see a portion that is broken due to the groove 20-1-J of metal 20-1, and the broken portion is filled with a connecting portion 20-5-C. This is consistent with the third modified example (…). Figures 9a to 9gThe difference lies in the fact that, in the fourth variation, the connecting portion 20-5-C is embedded in the groove 20-1-J itself, the outer side of the groove 20-1-J (in the width direction of the connector 20), and the inner side of the groove 20-1-J (in the width direction of the connector 20). Compared with the third variation, this can be seen as a factor that can further improve the bonding strength.

[0236] On the other hand, along Figure 10b The side profile view taken by line II' shown, i.e. Figure 10d In the image, the break due to the groove 20-1-J of metal 20-1 is not visible. This is because line HH' crosses groove 20-1-J, while line II' does not. Nevertheless, in Figure 10d The outer side of the third cover portion 20-1-C3 is also curved, and the connecting portion 20-5-C is embedded on the outer side (in the width direction of connector 20) of this curved portion and the inner side (in the width direction of connector 20) of the groove. In addition, compared with the basic embodiment and the first to third modified examples, this can be regarded as a factor that can further improve the bonding force.

[0237] Although the basic embodiments ( Figures 1 to 6 ), First variant ( Figures 7a to 7g ), second variation ( Figures 8a to 8g ), third variation ( Figures 9a to 9g ), Fourth variation ( Figures 10a to 10d The present invention has been described, but it is not limited to the various embodiments described. The respective components can be combined where there is no contradiction in their nature.

[0238] For example, the shape of the half-body in the fourth modification can also be applied to the basic embodiment, the first to third modifications (without violating their nature).

[0239] Additionally, for example, the structure in which the position of the inner joint 20-1-IJ overlaps with the position of the outer joint 20-1-OJ (in the length direction of the connector 20) in the basic embodiment can also be applied to the first to fourth modifications (without violating its nature).

[0240] Additionally, for example, the foregoing descriptions of the jack connector 20 may also apply to plug connectors (not shown) (socket connectors) to the extent that they are not contradictory in nature.

[0241] These variations are exemplary, and other variations are also possible.

[0242] 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.
