Description

Technical Field

[0001] The utility model relates to an electrical connector, and more specifically, to a structure of a receptacle connector (socket connector) combined with a plug connector as a mating connector. Background Art

[0002] Generally, in the case where substrates are connected to each other, two connectors connected to each substrate by a method 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 called 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] As electronic devices become smaller, connectors are becoming smaller and lower-profile. However, there is a certain degree of limitation in reducing the pitch or making the parts smaller to make connectors smaller and lower-profile.

[0004] On the other hand, as connectors become smaller, it is more difficult to ensure the durability of connectors than before. This is because the components are smaller and are more likely to be damaged or deformed even with less force than before.

[0005] In addition, as a type of deformation, if the metal terminal maintains a specific shape during the connection process between connectors or in the connected state, plastic deformation may occur. The so-called plastic deformation is the opposite concept of elastic deformation, which means that even if the load applied to the material is removed, the material will not return to its original shape and remain deformed. The reason is that all materials are usually elastic, but when stress is generated, the shape will be deformed. For the terminals of the increasingly miniaturized connectors, there is also a need to prevent this plastic deformation.

[0006] Furthermore, when a resin mold (housing) of a connector is manufactured by insert molding, whether the housing is properly molded depends on the fluidity of the resin. Therefore, there is a need to improve the fluidity of the resin.

[0007] Furthermore, when a terminal is usually made of a metal material, there are restrictions on the structure of the terminal itself and the resin mold depending on the manufacturing method (for example, whether to use a deep drawing method), so there is also a need to consider this point.

[0008] In insert molding, etc., there is also a need to consider the problem of the resin molded object covering the metal material. Utility Model Content

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

[0010] The technical problem to be solved by the present invention is to further reduce the manufacturing complexity by not using one-time molding to form a connector 20 with a complex shape (and / or a very small shape), or to make it easier to operate even a more complex structure (or a smaller structure) than before during manufacturing.

[0011] Another problem is to manufacture a connector 20 having a complex shape (and / or a very small shape) without using a single molding process, and to manufacture a connector 20 having a high overall strength by firmly combining separately manufactured components.

[0012] Another problem is to easily form a complex shape and / or a small shape with a relatively small number of insert molding times and to improve the strength of the connection.

[0013] Another problem is to manufacture a plurality of signal terminals 20 - 3 of the same shape and reuse and arrange them repeatedly to improve manufacturing efficiency.

[0014] Another problem is to make the width of the connector 20 smaller.

[0015] The technical issues of the present invention are not limited to the above-mentioned technical issues, and other technical issues not mentioned can be clearly understood by ordinary technicians according to the following description.

[0017] According to the utility model, an electrical connector is provided.

[0018] The electrical connector is mounted on a substrate and combined with a mating connector, comprising:

[0021] The left half body is a component in which the plurality of first terminals and the first fitting are integrated with a first shell as a shell of the left half body.

[0022] The right half body is a component in which the plurality of second terminals and the second fittings are integrated with a second shell as a shell of the right half body.

[0023] The left half body portion and the right half body portion are arranged in abutment with each other and are connected to each other through an additional molding.

[0024] Preferably, the left half body is a component in which the plurality of first terminals and the first fitting are integrated with the first housing formed by a first insert molding.

[0025] The right half body is a component in which the plurality of second terminals and the second fittings are integrated with the second housing formed by the first insert molding.

[0026] The left half body portion and the right half body portion are arranged in abutment with each other and are combined with each other by the additional molded object formed by the second insert molding.

[0027] Preferably, the left half body and the right half body are Shape or shape.

[0028] Preferably, when the left half body portion abuts against the right half body portion,

[0029] One end of the first terminal arrangement portion of the left half body is in contact with the second hardware arrangement portion of the right half body,

[0030] One end of the second terminal arrangement portion of the right half body is in contact with the first fitting arrangement portion of the left half body.

[0031] Preferably, there are receiving grooves on both sides of the first terminal arrangement portion of the left half body and on both sides of the second terminal arrangement portion of the right half body,

[0032] The additional molded object is received and combined in the receiving groove.

[0033] Preferably, when the left half body portion abuts against the right half body portion,

[0034] In the width direction of the electrical connector, the receiving groove of the left half body portion and the receiving groove of the right half body portion are arranged side by side.

[0035] Preferably, the additional molded object spans and is connected to the left half body portion and the right half body portion.

[0036] Preferably, an outer through hole penetrating in the width direction of the electrical connector is present at a portion where the left half body portion and the right half body portion are connected via the additional molded article.

[0037] Preferably, an inner through hole penetrating in the width direction of the electrical connector is present at a portion where the left half body portion and the right half body portion are connected via the additional molded article.

[0038] Preferably, the inner through holes are arranged side by side in the width direction of the electrical connector.

[0039] [Effects of the utility model]

[0040] According to the utility model, since the connector 20 having a complex shape (and / or a very small shape) can be manufactured without utilizing one-time molding, and can be manufactured separately into a left half and a right half, the following effects are produced: it can be considered that the complexity of manufacturing becomes lower, or even a more complex structure (or a smaller structure) than before can be more easily operated during manufacturing.

[0041] In addition, while the connector 20 having a complex shape (and / or a very small shape) is not manufactured by one-time molding and is divided into a left half and a right half, the additional molded object 20-5-2 can be firmly combined through the structure of the fixing portion (upper fixing portion and / or lower fixing portion), thereby manufacturing a connector 20 with high overall strength.

[0042] Made by first insert molding Figure 3a , Figure 3b state, and is made into the same as the Figure 3c The same state (finished state) can be easily made into complex shapes and / or small shapes through relatively few insert molding times, and in order to improve the strength of the combination, the shape, shape and / or upper and lower fixing parts.

[0043] exist Figure 3c In the embodiment, the plurality of signal terminals 20-3 are arranged in a zigzag shape, and the signal terminals 20-3 having only different arrangements but the same shape can be manufactured and used, thereby improving the manufacturing efficiency. Figure 5 The signal terminal 20-3 at the cutting surface is Figure 6 The signal terminals 20 - 3 at the cut surface can use the same terminals with only different arrangement directions, so the manufacturing efficiency is higher.

[0044] Observe the modified example of the present invention Figure 8 The signal terminal 20-3' has a bent portion 20-3-B' at the upper portion of the mounting portion 20-3-M'. Since the bent portion 20-3-B' is bent inward in the width direction of the connector 20, the corresponding portion becomes vertical (compared to the case where there is no corresponding bent portion). Figure 7The size of the connector 20, strictly speaking, the width of the connector 20, can be made smaller compared with the example of FIG.

[0045] However, this is just an example of the effect, and the effect brought about by the configuration of the present invention is of course not limited to this.

[0046] The effects of the present invention are not limited to the above-mentioned examples, and more various effects are included in this specification. BRIEF DESCRIPTION OF THE DRAWINGS

[0094] The advantages and features of the present invention, as well as methods for achieving the same, will become clear with reference to the accompanying drawings and the embodiments to be described in detail. However, the present invention is not limited to the embodiments disclosed below, but is implemented in various forms that are different from each other, and the present embodiments are provided only to make the disclosure of the present invention complete and to fully convey the scope of the present invention to those with ordinary knowledge in the technical field to which the present invention belongs, and the present invention is defined only by the scope of the claims. Throughout the entire specification, the same reference symbols refer to the same constituent elements.

[0095] Figure 1 It is a top perspective view of an embodiment of a receptacle connector 20 in an electrical connector according to the present invention.

[0096] In this specification, the electrical connector may be referred to as a plug connector (not shown) as appropriate, as appropriate, as a receptacle connector 20 (also called a "socket connector") as appropriate, or as a plug connector (not shown) and the receptacle connector 20 (or an assembly thereof) as appropriate.

[0097] The socket connector 20 is also referred to as a receptacle connector 20 .

[0098] Figure 1 The receptacle connector 20 is configured to be mated with a plug connector (not shown).

[0099] As an example, in Figure 1 2 shows the power terminal (metal fitting) 20-1, the signal terminal 20-3, and the housing 20-5 (mold portion) of the receptacle connector 20. In addition, an additional molded object 20-5-2 (for example, a second insert object) is also shown.

[0100] 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. The signal terminal 20-3 can input and output data signals.

[0101] However, this is an example and the present invention is not limited thereto. For example, the power terminal 20 - 1 may be manufactured by separating the metal fitting and the power terminal into separate parts.

[0102] exist Figure 1 In the figure, the fitting 20 - 1 is a power terminal and the terminal 20 - 3 is a signal terminal, but the present invention is not limited thereto. The fitting 20 - 1 may not be a power terminal and the terminal 20 - 3 may be a mixed signal terminal and a power terminal.

[0103] In addition, for example, the signal terminal 20-3 may also be composed of four pins (PIN) that allow a current of 0.3A, and may be a terminal that allows a current exceeding 0.3A, such as 5A, to function as a power supply terminal. However, the number of pins being four is an example. For reference, Figure 1 In the example, the number of signal terminals 20 - 3 is 16.

[0104] The housing 20-5 has a base portion 20-5-B (see Figure 2 The housing 20-5 has a wall portion protruding from the upper surface of the base portion 20-5-B, and the power terminal 20-1, the signal terminal 20-3, etc. are formed on the wall portion. In addition, the housing 20-5 not only has a wall portion (at the edge) protruding from the base portion, but also has an island portion 20-5-I (central island portion) (in the middle).

[0105] The wall portion is generally formed by 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. Figure 1 As shown, it can be observed that 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 are connected in the order, and the fourth wall portion 20-5-W4 is connected to the first wall portion 20-5-W1 again.

[0106] The housing 20-5 (mold part) of the socket connector 20 is preferably made of plastic material, such as liquid crystal polymer (LCP). In addition, the housing 20-5 can be formed of an insulator including resin and epoxy resin, but is not limited to this. The power terminal 20-1 and the signal terminal 20-3 of the plug connector 20 are preferably made of metal material, although not limited to this, but can also be copper, and the copper alloy can also be plated with gold (nickel base).

[0107] A plurality of signal terminals 20 - 3 are provided on the first wall portion 20 - 5 -W1 and the third wall portion 20 - 5 -W3 extending in the X direction (the longitudinal direction of the receptacle connector 20 ).

[0108] Figure 2 yes Figure 1 A top view of the jack connector 20 is shown.

[0109] Figure 1 and Figure 2 The jack connector 20 shown can be roughly divided into two parts (i.e., Figure 3a The left half 20-LH and the right half 20-RH). However, in Figure 1 , Figure 2 In the figure, only the combination of the left half body 20-LH and the right half body 20-RH is shown, so it may be slightly difficult to distinguish, but it will be described later. Figure 3a to Figure 3c Its specific composition is described.

[0110] Therefore, in Figure 2 In the figure, the shell (mold part) 20-5 is divided into a left half shell 20-5L and a right half shell 20-5R for marking.

[0111] In addition, Figure 2 In the figure, the central island portion 20-5-I is also divided into the central island portion 20-5L-I of the left half and the central island portion 20-5R-I of the right half and marked.

[0112] In addition, Figure 2In the figure, the base 20-5-B of the shell is also divided into a base 20-5L-B of the left half and a base 20-5R-B of the right half for marking.

[0113] Furthermore, an additional molded object 20-5-2 is also shown.

[0114] As mentioned above, Figure 2 The left half body 20-LH and the right half body 20-RH are combined, so it is slightly difficult to grasp the structure. Figure 3a to Figure 3c Elaborate in detail.

[0115] Figure 3a is formed Figure 2 (or Figure 3c ) of the jack connector 20 before the stage.

[0116] from Figure 2 The additional molding 20-5-2 is removed and the state in which the left half 20-LH and the right half 20-RH are separated in space is Figure 3a .

[0117] Of course, this is for conceptual purposes only. In actual manufacturing, Figure 3a After the process, it is also completed Figure 2 Connector 20.

[0118] exist Figure 3a In the figure, it can be seen that the housing 20-5L of the left half body 20-LH is combined with a hardware (and / or power terminal) 20-1 and a signal terminal 20-3. It can be seen that the left half body 20-LH is roughly in the shape of ".

[0119] Although not limited to this, the housing 20-5L is insert-molded (first insert-molded) by placing the metal fitting 20-1 and the signal terminal 20-3 at predetermined positions through the carrier, thereby obtaining Figure 3a The left half of the body is 20-LH.

[0120] In addition, Figure 3a In the figure, it can be seen that the housing 20-5R of the right half body 20-RH is combined with a hardware (and / or power terminal) 20-1 and a signal terminal 20-3. It can be seen that the right half body 20-RH is roughly in the shape of ".

[0121] As in the case of the left half 20-LH, although not limited thereto, the metal fitting 20-1 and the signal terminal 20-3 are located at a predetermined position by means of the carrier, and the housing 20-5R is insert-molded (first insert-molded), so that Figure 3a The right half of the body is 20-RH.

[0122] For reference, the formation of the left half body 20-LH is also referred to as the first insert molding, and the molding of the right half body 20-RH is also referred to as the first insert molding, but this does not mean that the two must be exactly the same insert molding or performed in exactly the same sequence. It means that it only needs to be performed before the second insert molding (manufacturing the additional molded product 20-5-2) described later.

[0123] For reference, although it is called the first insert molding and the second insert molding, the present invention is not necessarily limited to insert molding. However, in order to make a connector of a specific shape or a connector of a very small size, insert molding is very suitable, or it refers to a situation that can be achieved only by insert molding. As an example, the connector 20 of the shape shown in the figure is preferably formed by insert molding (the left half body 20-LH and the right half body 20-RH are formed by the first insert molding, and the additional molded object 20-5-2 is formed by the second insert molding).

[0124] The left half body 20 -LH has a hardware arrangement portion MA and a terminal arrangement portion TA. The right half body 20 -RH also has a hardware arrangement portion MA and a terminal arrangement portion TA.

[0125] For reference, although also about Figure 1 It has been described that the hardware 20-1 is a power terminal and the terminal 20-3 is a signal terminal as a typical example, but it is not limited to this. It can also be a form in which the hardware 20-1 is not a power terminal in the hardware arrangement part MA and the terminal 20-3 is a mixture of a signal terminal and a power terminal in the terminal arrangement part TA.

[0126] exist Figure 3a In the figure, the left half body 20-LH is in the "" shape" and the right half body 20-RH is in the "" shape" in order to make the "" shape" and the "" shape" match each other (refer to Figure 3b ).

[0127] Therefore, if the shape of the left half body 20 -LH and the shape of the right half body 20 -RH are combined and matched with each other, thereby expressing the outer shape of the connector 20 as a whole, it can also be slightly deformed thereby.

[0128] Also, although the expression is done with "shape" and "shape", the structure is slightly changed, so it can be seen that it becomes " Shape and Shape" is also acceptable. Below, for the convenience of explanation, even if " Shape and It can be used to express "shape" and "shape", and can also be used to mean "shape" and "shape".

[0129] Figure 3a is Figure 2In the state where the additional molding 20-5-2 is removed, the corresponding part has upper and lower ( Figure 3a The receiving groove AC is a through groove (in the Z direction).

[0130] It can be seen that there are two AC-Ls in the left half 20-LH and two AC-Rs in the right half 20-RH. Of course, two are just an example, and the structure and number can be changed as needed.

[0131] Since the connector 20 having such a complex shape (and / or a very small shape) can be manufactured without utilizing a one-time molding, and can be manufactured separately into a left half and a right half, the following effect is produced: it can be considered that the complexity of manufacturing is further reduced, or even a more complex structure (or a smaller structure) than before can be more easily handled during manufacturing.

[0132] Figure 3b yes Figure 3a The next stage is to form Figure 2 (or Figure 3c ) of the jack connector 20 before the stage.

[0133] Will Figure 3a The left half body 20-LH and the right half body 20-RH separated from each other are combined to form a Figure 3b Of course, this is only abutment, and it is not the state where the left half body 20-LH and the right half body 20-RH are connected. In order to connect the left half body 20-LH and the right half body 20-RH, Figure 3b The additional molded object 20-5-2 is formed in the state (for example, by a second insert molding), and the result is as follows Figure 3c (or Figure 2 ) as shown.

[0134] As an example, the metal fittings 20-1 and the signal terminals 20-3 fixed by a carrier (not shown) are formed into the housing 20-5L of the left half body 20-LH by one insert molding. Similarly, the metal fittings 20-1 and the signal terminals 20-3 fixed by another carrier (not shown) are formed into the housing 20-5R of the right half body 20-RH by one insert molding (not necessarily formed at the same time as the left half body), and by moving these carriers (not shown), as shown in FIG. Figure 3b As shown, the left half body 20 -LH is brought into contact with the right half body 20 -RH.

[0135] like Figure 3bAs shown, specifically, the left half body 20-LH and the right half body 20-RH are abutted, and one end of the terminal arrangement portion TA of the left half body 20-LH abuts against the hardware arrangement portion MA of the right half body 20-RH, and it is best if one end of the terminal arrangement portion TA of the right half body 20-RH abuts against the hardware arrangement portion MA of the left half body 20-LH.

[0136] like Figure 3b As shown, if the left half body 20-LH and the right half body 20-RH are in contact, it can be seen that in addition to the additional molding 20-5-2, it is Figure 3c (or Figure 2 )Connector 20 having the same appearance.

[0137] exist Figure 3b In the figure, fixing parts 20-5L-OH, 20-5L-IH, 20-5R-IH, and 20-5R-OH are shown. Due to the existence of these fixing parts, an additional molded object 20-5-2 is added thereto (for example, by secondary insert molding), thereby completing the connector 20.

[0138] Fixed part 20-5L-OH, 20-5L-IH, 20-5R-IH, 20-5R-OH Figure 3b 4 types (8 pieces) are shown in FIG. 1 , but below (in the -Z direction) the corresponding 4 types of fixing parts 20-5L-OH, 20-5L-IH, 20-5R-IH, 20-5R-OH (i.e., the upper fixing part), there are also Figure 4 The additional four fixing portions 20-5L-OL, 20-5L-IL, 20-5R-IL, 20-5R-OL (ie, lower fixing portions) are shown.

[0139] However, this is just an example, and a variation in which only the upper fixing portion or only the lower fixing portion exists is possible.

[0140] The connector 20 having such a complex shape (and / or a very small shape) is not manufactured by a one-time molding but is divided into a left half and a right half. At the same time, the additional molding 20-5-2 (described later) can be firmly combined through the structure of the fixing part (upper fixing part and / or lower fixing part), thereby manufacturing a connector 20 with overall high strength.

[0141] Figure 3c yes Figure 3b The next stage, while showing the jack connector 20 is completed, Figure 3c In addition to the differences in schematic symbols, Figure 2 same.

[0142] exist Figure 3c In, for ( Figure 3bThe upper fixing parts 20-5L-OH, 20-5L-IH, 20-5R-IH, 20-5R-OH and (shown in Figure 3b Not specified but Figure 4 The lower fixing parts 20-5L-OL, 20-5L-IL, 20-5R-IL, 20-5R-OL (shown in the figure) form an additional molded object 20-5-2, showing the completed jack connector 20.

[0143] That is, made by the first insert molding Figure 3a , Figure 3b state, and is made into the same as the Figure 3c The same state (finished state) can be easily made into complex shapes and / or small shapes through relatively few insert molding times, and in order to improve the strength of the combination, the shape, shape and / or upper and lower fixing parts.

[0144] Figure 3c The connector 20 shown in FIG. Figure 2 The shapes shown are the same.

[0145] but, Figure 3c The lines AA', BB' and CC' are marked as reference lines for observing the cross section. Figures 4 to 6 The cross section is explained in this article.

[0146] Figure 4 It means along Figure 3c A stereogram of a cross section taken along line AA'.

[0147] Along Figure 3c The line AA' is cut from Figure 3c The cut surface is observed from the left side to the right side, showing Figure 4 Shape shown.

[0148] As mentioned earlier, in Figure 3b Only the upper fixing parts 20-5L-OH, 20-5L-IH, 20-5R-IH, and 20-5R-OH are seen, and the lower fixing parts below them (-Z direction) are not seen. Figure 4 In the cross section, not only the four upper fixing parts 20-5L-OH, 20-5L-IH, 20-5R-IH, and 20-5R-OH are seen, but also the four lower fixing parts 20-5L-OL, 20-5L-IL, 20-5R-IL, and 20-5R-OL are seen. An additional molded object 20-5-2 is molded where these eight fixing parts exist (for example, by secondary insert molding).

[0149] The upper fixing part and the lower fixing part are part of the housing 20-5 (20-5L or 20-5R), and are preferably made of resin. The additional molded article 20-5-2 is also preferably made of resin, and can be the same material as the housing 20-5, or can be other types of resin.

[0150] By molding (forming) an additional molded article 20-5-2 which interposes such fixing parts 20-5L-OH, 20-5L-IH, 20-5R-IH, 20-5R-OH, 20-5L-OL, 20-5L-IL, 20-5R-IL, 20-5R-OL, the left half 20-LH and the right half 20-RH are firmly combined.

[0151] Figure 5 It means along Figure 3c A cross-section of line BB'.

[0152] Along Figure 3c The line BB' is cut from Figure 3c The cut surface is observed from the left side to the right side, showing Figure 5 Shape shown.

[0153] observe Figure 5 , it can be seen that the signal terminals 20 - 3 of the same shape are arranged in the same direction. Figure 3c In the embodiment, the plurality of signal terminals 20 - 3 are arranged in a zigzag shape, and the signal terminals 20 - 3 having only different arrangements but the same shape can be manufactured and used, thereby improving the manufacturing efficiency.

[0154] Figure 6 It means along Figure 3c A cross-section of line CC'.

[0155] Along Figure 3c The line CC' is cut from Figure 3c The cut surface is observed from the left side to the right side, showing Figure 6 Shape shown.

[0156] observe Figure 6 , it can be seen that the signal terminals 20-3 of the same shape are arranged in the same direction. However, it can be seen that Figure 6 The signal terminal 20-3 at the cutting surface is in the same direction as Figure 5 The signal terminals 20-3 at the cutting surface are in different directions. Figure 3c Overlooking Figure 1 By observing them, we can know their positional relationship.

[0157] exist Figure 3cIn the embodiment, the plurality of signal terminals 20-3 are arranged in a zigzag shape, and the signal terminals 20-3 having only different arrangements but the same shape can be manufactured and used, thereby improving the manufacturing efficiency. Figure 5 The signal terminal 20-3 at the cutting surface is Figure 6 The signal terminals 20 - 3 at the cut surface can use the same terminals with only different arrangement directions, so the manufacturing efficiency is higher.

[0158] However, (1) Figure 5 The two terminals on the cut surface have the same shape, (2) Figure 6 The two terminals on the cut surface have the same shape, (3) Figure 5 The two terminals of the cutting surface are Figure 6 The two terminals (i.e., a total of four terminals) on the cut surface of the same shape is an example and is not necessarily limited to this. That is, even if the manufacturing efficiency is reduced, signal terminals of different shapes can be used in (1), (2), and / or (3) as needed.

[0159] Figure 7 Yes means Figure 6 Part of the diagram.

[0160] Although not limited to this, Figure 7 For example, the signal terminal 20 - 3 has no bent portion at the upper portion of the mounting portion 20 - 3 -M (which has only a small groove).

[0161] That is, there is no bent portion, and the distance in the width direction between the width direction outermost portion (lower outer portion) 20 - 3 -OL and the width direction outer portion (upper outer portion) 20 - 3 -OH of the signal terminal 20 - 3 is L1.

[0162] Figure 8 It is an example of the present invention. Figure 7 FIG. 1 is a diagram of a modified example of .

[0163] In the modified example of the present invention Figure 8 In the figure, at the upper part of the mounting part 20-3-M', there is a bent portion 20-3-B' which bends inward in the width direction of the connector 20. Therefore, the distance in the width direction between the outermost portion in the width direction (lower outer portion) 20-3-OL' of the signal terminal 20-3' and the outer portion in the width direction (upper outer portion) 20-3-OH' located above the bent portion 20-3-B' is L2.

[0164] According to a modified example of the present invention Figure 8 An example of Figure 7Compared with the case of L2, the width of the connector 20 can be reduced to twice the difference between L2 and L1 (ie, (L2-L1)*2.

[0165] In addition, for example, the aforementioned matters described with respect to the receptacle connector 20 (socket connector) can also be applied to a plug connector (not shown) within the limit not contradictory in nature.
