Description

Technical Field

[0001] The present utility model relates to an electrical connector. More specifically, the present utility model relates to the structure of a receptacle connector (socket connector) combined with a plug connector and their combination (assembly). Background Art

[0002] Generally, when substrates are interconnected, two connectors connected to each substrate by methods such as soldering are used, and the two connectors can be connected to each other. Here, one of the two connectors is a plug connector, and the other is a socket connector. The socket connector is also referred to as a receptacle connector. Such a plug connector and a socket connector can be formed by arranging terminals in a mold part. The plug connector and the socket connector can be fastened to each other to form an electrical connector assembly.

[0003] With the trend of miniaturization of electronic devices, miniaturization and low-profile of connectors are trends. However, in fact, there are certain limitations in reducing the pitch or making parts smaller to miniaturize and low-profile the connectors.

[0004] On the other hand, while the connectors are miniaturized, it is also difficult to ensure the durability of the connectors compared to before. The reason is that due to the small size of the components, even a smaller force than before can easily cause them to break or deform.

[0005] In addition, as a type of such deformation, during the combination process between connectors or in the combined state, if the terminals made of a metal material always maintain a specific shape, plastic deformation may occur. Plastic deformation, as the opposite concept of elastic deformation, means that even if the load applied to the material is removed, the material will not return to its original shape and will remain in the deformed state. The reason is that all materials generally have elasticity, but when stress is generated, the shape will be deformed. For the terminals of the gradually miniaturized connectors, there is also a need to prevent such plastic deformation.

[0006] Moreover, there is a case where a resin mold (housing) of a connector is made by insert molding. At this time, whether the housing is correctly molded is determined according to the fluidity of the resin, so there is also a need to improve the fluidity of the resin.

[0007] In addition, generally when making terminals made of a metal material, there are also limitations on the structure of the terminals themselves and the resin mold according to the manufacturing method (for example, whether the deep drawing method is used), so there is also a need to consider this point.

[0008] In addition, in insert molding and the like, it is also necessary to consider the problem points regarding the resin injection covering the metal material. Summary of the Utility Model

[0009] [Problems to be Solved by the Utility Model]

[0010] The technical problem to be solved by the present utility model is to solve the problem of low conductivity of the terminals produced by deep drawing processing.

[0011] In addition, another problem of the present utility model is to solve the problem of possible lead combustion when the power supply terminals (metal fittings terminals) are made into multiple blocks.

[0012] In addition, another problem of the present utility model is to make the strength of fastening with the mating connector (elastic force of the fastening part) adjustable.

[0013] In addition, another problem of the present utility model is to make the manufacturing / processing easier.

[0014] The technical problems of the present utility model are not limited to the above-mentioned technical problems, and for those of ordinary skill in the art, other technical problems not mentioned can be clearly understood according to the following description.

[0059] When the plug connector is combined with the jack connector, the first movable contact part and the second movable contact part respectively contact the central island covering part of the jack connector.

[0060] [Effects of the utility model]

[0061] According to the present utility model, due to the complex shape of the first metal fitting terminal 20-11, it is suitable to be processed by deep drawing. Therefore, if a material with high workability is used, the conductivity is somewhat poor, and thus there may be a situation where it is difficult to pass a large current. (This is not limited to this, but even if the workability is somewhat reduced compared to the first metal fitting terminal 20-11), if the second metal fitting terminal 20-12 is made of another material with better conductivity and the two 20-11 and 20-12 are used together, it has the effect of having the workability of the first metal fitting terminal 20-11 as it is and having high conductivity as a whole for the first metal fitting terminal 20-11 and the second metal fitting terminal 20-12.

[0062] The shape of the second metal fitting terminal 20-12 is simpler than that of the first metal fitting terminal 20-11. Therefore, it can also be manufactured by other processing methods other than deep drawing. Even in the case of deep drawing the second metal fitting terminal 20-12, since the processing degree is lower compared to the first metal fitting terminal 20-11, the above effects brought by using materials with different conductivities to each other are still produced.

[0063] In summary, by adding the shape of the second fitting terminal 20-12 as a contact terminal made of another material to the first fitting terminal 20-11 fabricated by deep drawing process, the second fitting terminal 20-12 made of another material (a material with better conductivity) is added to compensate for the shortcomings of the first fitting terminal 20-11 that is difficult to handle high current alone, and thus high current can be handled as a whole.

[0064] On the other hand, if the first connection part covering part 20-5-B1 and the second connection part covering part 20-5-B2 (which are parts of the housing 20-5) cover the first connection part 20-12-B1 and the second connection part 20-12-B2 (which are parts of the second fitting terminal 20-12), when the bottom surfaces of the first connection part 20-12-B1 and the second connection part 20-12-B2 (that is, the bottom surfaces when observed in the -Z direction, rather than the surfaces shown in Figure 3 are used as the mounting parts for mounting on a substrate (not shown), it has the effect of preventing lead burning. Figure 3 That is, if the first connection part covering part 20-5-B1 and the second connection part covering part 20-5-B2 (which are parts of the housing 20-5) do not exist, solder may flow in through the gap between the first fitting terminal 20-11 and the second fitting terminal 20-12 shown in

[0065] or through the other side of the second fitting terminal 20-12 (which is the opposite side of the connector length direction of this gap), which will have an adverse impact on the completion degree of the connector 20. Figure 3 That is, if the first connection part covering part 20-5-B1 and the second connection part covering part 20-5-B2 (which are parts of the housing 20-5) do not exist, solder may flow in through the gap between the first fitting terminal 20-11 and the second fitting terminal 20-12 shown in

[0066] In addition, according to the Figure 7 deformation example, since the elastic force provided by the central island part covering part 20-12-CI is smaller than that in the case of Figure 3 , the fastening with the mating connector (plug connector 10) can become easier. Of course, it can be seen that this is also related to the combination state with the housing 20-5. Therefore, rather than simply saying that the elastic force increases / decreases, it is more rigorous to say that the elastic force becomes different (adjustable).

[0067] In addition, since the number of bent parts (inverted U-shaped parts) is less than that in the structure of Figure 3 compared with the structure of Figure 7 , the manufacturing / processing difficulty can become easier.

[0068] However, this is just an example of the effect. Of course, the effects brought by the constitution of the present utility model are not limited to this.

[0069] The effects of the present utility model are not limited by the above-exemplified content, and more diverse effects are included in this specification. Description of the Drawings

[0110] With reference to the accompanying drawings and the embodiments to be described in detail below, the advantages, features, and the methods for achieving them of the present utility model will become apparent. However, the present utility model is not limited to the embodiments disclosed below, but can be implemented in various different forms, and the present embodiments are provided only to make the disclosure of the present utility model complete and to fully convey the scope of the utility model to those of ordinary skill in the technical field to which the present utility model pertains, and the present utility model is only defined by the scope of the claims. Throughout the specification, the same reference signs refer to the same components.

[0111] Figure 1 It is a top surface perspective view of an embodiment of a jack connector 20 and a plug connector 10 in an electrical connector according to the present utility model.

[0112] In this specification, the term "electrical connector" may, depending on the circumstances, use the term "plug connector 10", may, depending on the circumstances, use the term "jack connector 20 (also referred to as a'socket connector')", and may, depending on the circumstances, use the term for both the plug connector 10 and the jack connector 20 (or their assembly).

[0113] The socket connector 20 is also referred to as the jack connector 20.

[0114] Figure 1 The jack connector 20 of is a structure that is fitted and combined with the plug connector 10.

[0115] In Figure 1 As an example, the power terminal 20-1 (also referred to as a fitting terminal), the signal terminal 20-3, and the housing 20-5 (mold part) of the jack connector 20 are shown.

[0116] The power terminal 20-1 is a metal structure for supplementing the strength of the connector 20 and can input and output power electrical signals. In Figure 1 In the example of, the fitting terminal (power terminal) 20-1 of the present utility model includes a first fitting terminal 20-11 and a second fitting terminal 20-12 as separate parts. The first fitting terminal 20-11 and the second fitting terminal 20-12 may be made of different materials.

[0117] The signal terminal 20-3 can input and output data signals. In Figure 1 In the example of, the signal terminal 20-3 of the present utility model includes separate first signal terminal 20-31 and second signal terminal 20-32 with different shapes from each other.

[0118] However, this is just an example and is not limited thereto.

[0119] In addition, for example, the signal terminal 20-3 may also be composed of four pins (PINs) that can withstand a current of 0.3 A, and can be a terminal that can withstand a current exceeding 0.3 A, such as 5 A, to function as a power supply terminal. However, the number of pins being four is just an example. For reference, in Figure 1 in the example of

[0120] the housing 20-5 has a base portion 20-5-B. The housing 20-5 has a wall portion protruding from the upper surface of the base portion, and power terminals 20-1, signal terminals 20-3, etc. are formed on the wall portion. In addition, the housing 20-5 not only has a (peripheral) wall portion protruding from the base portion, but also has an island portion 20-5-I (central island portion) (in the middle).

[0121] The wall portion is generally formed of four parts, including a first wall portion 20-5-W1, a second wall portion 20-5-W2, a third wall portion 20-5-W3, and a fourth wall portion 20-5-W4. As Figure 1 shown, it can be observed that they are connected in the order of the first wall portion 20-5-W1 - the second wall portion 20-5-W2 - the third wall portion 20-5-W3 - the fourth wall portion 20-5-W4, and the fourth wall portion 20-5-W4 is connected to the first wall portion 20-5-W1 again.

[0122] The housing 20-5 (mold portion) of the socket connector (jack connector) 20 is preferably made of plastic, such as Liquid Crystal Polymer (LCP). In addition, the housing 20-5 can be formed of an insulator including resin and epoxy resin, etc., but is not limited thereto. The power terminals 20-1 and signal terminals 20-3 of the plug connector 20 are preferably made of metal. Although not limited thereto, it can be, for example, copper, and the copper alloy can also be gold-plated (with a nickel underlayer).

[0123] A plurality of signal terminals 20-3 are provided at the first wall portion 20-5-W1 and the third wall portion 20-5-W3 that extend in the X direction (the length direction of the jack connector 20).

[0124] Figure 2 is Figure 1 a top view and a partially enlarged view of the jack connector 20 and the plug connector 10.

[0125] Through Figure 2 the top view of Figure 1 the fitting terminals 20-1, signal terminals 20-3, housing 20-5, etc. shown in the perspective view of

[0126] The hardware terminal 20-1 includes a first hardware terminal 20-11 and a second hardware terminal 20-12.

[0127] The signal terminal 20 - 3 includes a first signal terminal 20 - 31 and a second signal terminal 20 - 32 .

[0128] The shell 20-5 includes a base portion 20-5-B, a central island portion 20-5-I, a first wall portion 20-5-W1, a second wall portion 20-5-W2, and a third wall portion 20-5-W3.

[0129] Figure 3 is Figure 1 , Figure 2 In the receptacle connector 20, the housing 20-5 and the signal terminal 20-3 are virtually removed and only the hardware terminal 20-1 on one side is shown separately.

[0130] exist Figure 3 Again, it is stated Figure 1 The upper right side or Figure 2 The power terminal (fitting terminal) 20-1 at the upper right end.

[0131] The second fitting terminal 20 - 12 is spaced apart from the first fitting terminal 20 - 11 in the length direction of the receptacle connector 20 and is arranged inside.

[0132] exist Figure 3 In the embodiment, the first hardware terminal 20-11 in the power terminal (hardware terminal) 20-1 includes a first covering portion 20-11-C1 covering the first wall portion 20-5-W1, a second covering portion 20-11-C2 covering the second wall portion 20-5-W2, and a third covering portion 20-11-C3 covering the third wall portion 20-5-W3. Moreover, when observing the upper surface, there is a bottom (bottom surface) 20-11-B of the power terminal 20-1 surrounded by the first covering portion 20-11-C1, the second covering portion 20-11-C2, and the third covering portion 20-11-C3.

[0133] Furthermore, a central island covering portion 20-11-CI may be additionally formed as necessary.

[0134] In addition to the first hardware terminal 20-11, the second hardware terminal 20-12 is also shown. Figure 3 When observed in the middle, it includes covering the first wall portion 20-5-W1 (refer to Figure 1 , Figure 2The fourth covering part 20-12-C4 that covers , the fifth covering part 20-12-C5 that covers the third wall part 20-5-W3, and the central island part covering part 20-12-CI that covers the central island part 20-5-I. The fourth covering part 20-12-C4 and the central island part covering part 20-12-CI are connected by the first connecting part 20-12-B1, and the central island part covering part 20-12-CI and the fifth covering part 20-12-C5 are connected by the second connecting part 20-12-B2.

[0135] For reference, in Figure 1 or Figure 2 the first connecting part 20-12-B1 and the second connecting part 20-12-B2 of Figure 3 cannot be seen, and it can be known that they are covered by the housing 20-5 (specifically, observing Figure 2 , they are covered by the first connecting part covering part 20-5-B1 and the second connecting part covering part 20-5-B2 that are part of the housing 20-5 and are not exposed).

[0136] Thus, if the first connecting part 20-12-B1 and the second connecting part 20-12-B2 (which are part of the second fitting terminal 20-12) are covered by the first connecting part covering part 20-5-B1 and the second connecting part covering part 20-5-B2 (which are part of the housing 20-5), then when installing the bottom surface of the first connecting part 20-12-B1 and the second connecting part 20-12-B2 (that is, the bottom surface when observed in the -Z direction of Figure 3 instead of the surface shown in Figure 3 ) as the mounting part for the substrate (not shown), it has the effect of preventing lead burning.

[0137] That is, if there is no first connecting part covering part 20-5-B1 and second connecting part covering part 20-5-B2 (which are part of the housing 20-5), then solder may flow in through the gap between the first fitting terminal 20-11 and the second fitting terminal 20-12 shown in Figure 3 , or through the other side of the second fitting terminal 20-12 (which is the opposite side of the connector length direction of this gap), which will have an adverse effect on the completion degree of the connector 20.

[0138] In addition, in Figure 3 the additional central island part covering part 20-11-CI of the first fitting terminal 20-11 and the central island part covering part 20-12-CI of the second fitting terminal 20-12 are shown, but the present invention is not limited to Figure 3 the illustration of Figure 3In another example different from the figure, there is no additional central island covering portion 20-11-CI, and the corresponding portion may also be in a flat form like the bottom 20-11-B. As another example, there may be no additional central island covering portion 20-11-CI, and the central island covering portion 20-12-CI of the second fitting terminal 20-12 is in a form that covers the end portion of the central island 20-5-I (that is, the end portion of the central island 20-5-I is not in the area of ​​the first fitting terminal 20-11, but in the area of ​​the second fitting terminal 20-12).

[0139] That is, the central island covering portion 20-12-CI of the second fitting terminal 20-12 may cover the end portion of the central island 20-5-I or may cover a portion other than the end portion.

[0140] Figure 4 is Figure 1 , Figure 2 In the plug connector 10, the housing 10-5 and the signal terminal 10-3 are virtually removed, and only the hardware terminal (power terminal) 10-1 on one side is shown separately.

[0141] exist Figure 4 Two movable contact portions 10 - 1 -C are shown in FIG.

[0142] However, the number of movable contact portions 10-1-C is not limited to two. Moreover, the movable contact portion 10-1-C is shown to be formed in the area corresponding to the second fitting terminal 20-12 (when combined with the receptacle connector 20), but it is not excluded that it is additionally formed in the area corresponding to the first fitting terminal 20-11.

[0143] Will Figure 4 The hardware terminal 10-1 is turned upside down and Figure 3 When the hardware terminal 20-1 is combined, the two movable contact parts 10-1-C contact both sides of the central island cover part 20-12-CI to supply power.

[0144] Of course, in Figure 1 In the condition also shown in FIG. 1 , the plug connector 10 is turned upside down and combined with the receptacle connector 20. Figure 2 The same is true in .

[0145] The first hardware terminal 20 - 11 and the second hardware terminal 20 - 12 may be made of different materials.

[0146] More specifically, the first fitting terminal 20-11 has a relatively complex shape, while the second fitting terminal 20-12 has a relatively simple shape. In such a case, a structure without a notch (without a cut section) like the first fitting terminal 20-11 is preferably processed by deep drawing, and for this purpose, a material with high workability is required. However, among materials with high workability, there are materials with poor electrical conductivity. Therefore, if it is desired to function smoothly as a power supply terminal, better electrical conductivity is needed. Thus, the second fitting terminal 20-12 is made of a material with better electrical conductivity than the first fitting terminal 20-11 alone, so as to pursue efficiency from the perspective of electrical conductivity.

[0147] That is, due to the complex shape of the first fitting terminal 20-11, it is suitable to be processed by deep drawing. Therefore, if a material with high workability is used, the electrical conductivity is somewhat poor, and there may be a situation where it is difficult to pass a large current. (This is not limited to this, but even if the workability is somewhat reduced compared to the first fitting terminal 20-11), if the second fitting terminal 20-12 is made of another material with better electrical conductivity and these two 20-11 and 20-12 are used together, the workability of the first fitting terminal 20-11 can be maintained as it is, and at the same time, the overall electrical conductivity of the first fitting terminal 20-11 and the second fitting terminal 20-12 is also high.

[0148] Since the shape of the second fitting terminal 20-12 is simpler than that of the first fitting terminal 20-11, it can also be made by other processing methods rather than deep drawing. Even in the case of deep drawing the second fitting terminal 20-12, since the processing degree is lower compared to the first fitting terminal 20-11, the above-mentioned effect brought by using materials with different electrical conductivities still occurs.

[0149] In summary, by using the first fitting terminal 20-11 made by deep drawing processing, adding the shape of the second fitting terminal 20-12 as a contact terminal of another material, thus adding the second fitting terminal 20-12 of another material (a material with better electrical conductivity) to make up for the shortcomings of the first fitting terminal 20-11 that is difficult to handle high current alone, and then the overall can handle high current.

[0150] Figure 5 It is a top view showing the state where the jack connector 20 and the plug connector 10 are combined.

[0151] Related to Figure 5 the XYZ coordinate system, from the perspective of the jack connector 20, it is the same as the coordinate system shown in Figure 1 , Figure 2 , Figure 3 and from the perspective of the plug connector 10, it is in Figure 1 , Figure 2 ,Figure 4 In the coordinate system shown, the plug connector 10 is combined with its top and bottom reversed.

[0152] That is, in Figure 5 the state of combination shown, the surface of the plug connector 10 is not the upper surface of the plug connector 10 shown in Figure 1 or Figure 2 but the bottom surface seen in the -Z direction with Figure 1 as a reference.

[0153] In order to observe the cut surface in Figure 6 described below, a line AA' is marked in Figure 5 ..

[0154] Figure 6 is a cross-sectional view showing the cut surface along the line AA' in the state of combination as shown in Figure 5 ..

[0155] Figure 6 shows a state in which the plug connector 10 is arranged above and the jack connector 20 is arranged below and they are combined with each other.

[0156] That is, compared with the XYZ coordinate system of Figures 1 to 4 , in Figure 5 the coordinate system of the jack connector 20 remains the same, while the plug connector 10 is in a state of being combined with its top and bottom reversed.

[0157] In Figure 6 the movable contact portion 10-1-C of the power terminal (metal fitting terminal) 10-1 of the plug connector 10 is in contact with the central island portion covering portion 20-12-CI of the second metal fitting terminal (second power terminal) 20-12 of the jack connector 20 to supply power.

[0158] The reasons and effects for separately forming the first metal fitting terminal 20-11 and the second metal fitting terminal 20-12 are as described above.

[0159] Moreover, in Figure 6 the lower surfaces of the first connection portion 20-12-B1 and the second connection portion 20-12-B2 are used as mounting surfaces for a substrate (not shown), and the first connection portion covering portion 20-5-B1 and the second connection portion covering portion 20-5-B2, which are part of the housing 20-5, are formed on the upper surfaces of the first connection portion 20-12-B1 and the second connection portion 20-12-B2.

[0160] Although not limited thereto, the effect of preventing lead combustion during installation by forming the first connection portion covering portion 20-5-B1 and the second connection portion covering portion 20-5-B2 is as described above.

[0161] Moreover, asFigure 6 As shown in Figure 5 in the cross-section along the AA' line of , the fourth covering portion 20-12-C4, the fifth covering portion 20-12-C5, and the central island portion covering portion 20-12-CI of the second fitting terminal 20-12 are each in an inverted U shape when observed in the cross-section in the width direction of the jack connector 20 (i.e., the cross-section along the AA' line).

[0162] Figure 7 FIG. is a diagram showing a modified example of the present utility model.

[0163] Figure 7 The first fitting terminal 20-11 and the second fitting terminal 20-12 of Figure 3 are different in shape from both of .

[0164] In Figure 7 the modified example of , the central island portion covering portion 20-12-CI has a central island portion end covering portion 20-12-CI' that extends in the length direction of the jack connector 20 (in the -X direction in Figure 7 ) and covers the end (the outermost end) of the central island portion 20-5-I. The central island portion end covering portion 20-12-CI' can also be regarded as a part of the central island portion covering portion 20-12-CI.

[0165] At this time, as Figure 7 shown, it can be seen that a part of the bottom 20-11-B of the first fitting terminal 20-11 is avoided (a part of the central portion is cut compared to Figure 3 ), and the central island portion end covering portion 20-12-CI' is located in this avoided space.

[0166] Therefore, the central island portion end covering portion 20-12-CI' overlaps with the first covering portion 20-11-C1 and the third covering portion 20-11-C3 of the first fitting terminal 20-11 in the length direction of the jack connector (i.e., the X direction). As shown in one example of the overlap in the length direction Figure 7 when expressing the same situation differently, it can also be expressed as in Figure 7 in the cross-section cut in the width direction along the BB' line in , in the cross-section in the corresponding width direction, the cross-section of the central island portion end covering portion 20-12-CI', the cross-section of the first covering portion 20-11-C1, and the cross-section of the third covering portion 20-11-C3 are simultaneously observed.

[0167] On the other hand, in Figure 3As can be seen from the example, the central island portion covering portion 20-12-CI does not overlap with the first covering portion 20-11-C1 and the third covering portion 20-11-C3 of the first metal fitting terminal in the length direction (i.e., the X direction) of the jack connector. When expressing the same situation differently, non-overlapping in the length direction (i.e., Figure 3 This situation can also be expressed as in Figure 3 In a certain plane cut in the width direction in

[0168] In Figure 7 In the case of a modified example, it can be obtained by performing deep drawing on the central island portion end covering portion 20-12-CI', or can also be obtained by other processing. If it is other processing that is not deep drawing, then as described above, the effect of the basic embodiment of "for the second metal fitting terminal 20-12, a material with good processability may not be selected so as to sacrifice conductivity" is normally exerted. On the other hand, differently, even if deep drawing is performed to obtain the central island portion end covering portion 20-12-CI', since the processing area or degree of the central island portion end covering portion 20-12-CI' is lower than the overall processing degree of the first metal fitting terminal 20-11, it can also have the effect of "for the second metal fitting terminal 20-12, it is not necessary to sacrifice the conductivity to a very large extent in order to improve the processability" (that is, in the selection of the material of the second metal fitting terminal 20-12, it may be necessary to use a material with slightly higher processability even if sacrificing conductivity slightly, but compared with the case of the material selection of the first metal fitting terminal 20-11, the degree of restriction is small).

[0169] In Figure 7 Of course, the cross-section along the AA' line is also the same as or similar to that of Figure 5 Or Figure 6 In this case, in the cross-section along the AA' line, when observing the fourth covering portion 20-12-C4, the fifth covering portion 20-12-C5, and the central island portion covering portion 20-12-CI of the second metal fitting terminal 20-12 in the cross-section in the width direction of the jack connector 20 (i.e., the cross-section along the AA' line), they are respectively in an inverted U shape.

[0170] On the other hand, in Figure 7 In the central island portion end covering portion 20-12-CI', there is a cut portion 20-12-CA, so the processability is improved and the shape of the central island portion end covering portion 20-12-CI' is easily formed.

[0171] Figure 8 FIG. [FIGURE NUMBER] shows another modified example of the present utility model.

[0172] In Figure 3 the center island portion covering part 20-12-CI is a single block, while in Figure 8 a modified example, the center island portion covering part 20-12-CI is divided into two blocks, namely the first center island portion covering part 20-12-CI1 and the second center island portion covering part 20-12-CI2.

[0173] Of course, it can thus be seen that the second metal fitting terminal 20-12 itself is divided into two blocks.

[0174] It is not limited thereto, but according to Figure 8 a modified example, compared with the situation of Figure 3 , since the elastic force provided by the center island portion covering part 20-12-CI is smaller, the fastening with the mating connector (plug connector 10) can become easier. Of course, it can be seen that this is also related to the combined state with the housing 20-5. Therefore, rather than simply saying that the elastic force increases / decreases, it is more accurate to say that the elastic force becomes different (adjustable).

[0175] In addition, since the number of bent parts (inverted U-shaped parts) is less than that of Figure 3 the structure of Figure 8 , the manufacturing / processing difficulty can become easier.

[0176] In addition, for example, regarding the foregoing matters described for the jack connector (socket connector) 20, they can also be applied to the plug connector 10 within the limit that their natures do not conflict.

[0177] The embodiments of the present utility model have been described above with reference to the accompanying drawings. However, the present utility model is not limited to the described embodiments and can be manufactured in various different forms. Those with ordinary knowledge in the technical field to which the present utility model belongs can understand that other specific forms can be implemented without changing the technical idea or essential features of the present utility model. Therefore, the embodiments described above should be understood as illustrative in all aspects and not restrictive.
