Description

Technical Field

[0001] The utility model relates to an electric connector, and more specifically, to a structure of a hardware terminal and a movable terminal of an electric connector (a plug connector or a receptacle connector (socket 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 utility model is to provide a connector which has no expansion field interference and has few restrictions on the shape, detailed structure and size of the product.

[0011] Another object of the present invention is to provide bending portions 10-2-B, 10-2-B', 10-2-B" with appropriate shapes and positions to solve the problem of lead burning or the problem of resin position selection when filling resin.

[0012] Another object of the present invention is to provide a connector using a drawing process without interference of the expansion field.

[0013] Another object of the present invention is to further increase the mounting pitch relative to the actual pitch of the terminals by optimizing the arrangement of the signal terminals and the like.

[0014] Another object of the present invention is to make it easy to check the mounting state through the through hole 10-5-PH and the like.

[0015] However, this is just one example of the effect, and the effects brought about by the configuration of the present invention are of course not limited to this.

[0017] [Technical means to solve the problem]

[0018] According to the utility model, an electrical connector is provided, which is an electrical connector combined with a mating connector, and is characterized by comprising:

[0019] The housing comprises: a base portion; a first wall portion protruding from the upper surface of the base portion; a second wall portion protruding from the upper surface of the base portion and intersecting the first wall portion; a third wall portion protruding from the upper surface of the base portion, intersecting the second wall portion and facing the first wall portion; and a fourth wall portion protruding from the upper surface of the base portion, intersecting the first wall portion and the third wall portion and facing the second wall portion;

[0048] Preferably, a third cutout portion is formed in the third mounting portion.

[0049] The connecting portion of the movable terminal is inserted into the third cut portion and positioned.

[0050] [Effects of the utility model]

[0051] According to the utility model, since there is no expansion field interference, the constraints on the shape, detailed structure and size of the product are reduced.

[0052] For example, Fig.12a , Figure 12b Comparative examples (from the chronological order of production, Figure 12b The shape is preferred, so that it is partially bent as Fig.12a manufactured as shown). Figure 12b Did not Fig.12a The hardware 100 is fully unfolded, and only the part inside the dotted line A (spread) is unfolded. Figure 12bThere is a constraint that the guide part 100-G cannot touch the connecting part 100-C at the dotted line B. That is, when unfolded into the unfolded field, the interval of the dotted line B portion becomes narrow, and it becomes impossible to produce or is limited in reducing the width depending on the situation.

[0053] Furthermore, even if it is not necessarily only the guide portion 100-G within the dotted line B, there are also limitations on the manufacturing size of other parts. Figure 12b The expansion pattern does not touch (no expansion field interference), then Figure 12b Proper bending to make Fig.12a Three-dimensional shape.

[0054] In contrast, in the connector of the present invention, Figure 12b Generally, a metal sheet is bent to make a hardware (also used as a power terminal). Figures 3 to 6 (a) Figure 6 (b) (first embodiment), Figures 9 to 11 (Second embodiment) The number of common hardware 10-1 and power terminal 10-2 is greatly reduced.

[0055] Furthermore, it also has the effect of reducing the width of the product (connector). Figure 12b In the method shown in (Comparative Example), the minimum width required to manufacture all structures is Figures 3 to 6 (a) Figure 6 (b) (first embodiment), Figures 9 to 11 The method of (Second Embodiment) can be further reduced.

[0056] In addition, Fig.13 In (a), (b), and (c), the lead is prevented from burning by the bent portions 10-2-B, 10-2-B', and 10-2-B". Although not limited to this, Fig.13 In the shape of (a), the lead enters the space where it rises and then falls, which prevents the lead from spreading to other parts unnecessarily. Fig.13 (b) and Fig.13 In the shape of (c), the lead enters the space of the portion where there is a height difference between the connecting portion 10-2-C' or 10-2-C" and the bending portion 10-2-B' or 10-2-B", which can prevent the lead from unnecessarily diffusing to other portions.

[0057] Furthermore, it can be observed that the first curved surface 10 - 1 - B1 , the second curved surface 10 - 1 - B2 , and the third curved surface 10 - 1 - B3 are continuously formed without being cut, which can be achieved by manufacturing the hardware 10 - 1 by, for example, a stretching process.

[0058] In particular, there is a first outer connecting surface 10-1-D1 between the first curved surface 10-1-B1 and the second curved surface 10-1-B2, forming curved surfaces that are continuous with each other. In particular, there is a second outer connecting surface 10-1-D2 between the second curved surface 10-1-B2 and the third curved surface 10-1-B3, forming curved surfaces that are continuous with each other. This structure is slightly difficult to obtain in the forging (press) process, but can be obtained through the stretching process.

[0059] In addition, it can be observed that the signal terminals 10-3 are arranged in two mixed ways (as an example, the signal terminals 10-3 of one type with the same shape are arranged in two ways by simply changing the direction). Figure 1 In the embodiment, the signal terminals 10-3 run in the length direction (X direction) of the connector 10, and the mounting portions 10-3-M are alternately arranged in a manner that they are once located on the outside in the width direction of the connector and once located on the inside in the width direction of the connector (seen through the through hole 10-5-PH). In addition, among the multiple mounting portions 10-3-M located on the inside in the width direction (Y direction) of the connector 10, the mounting portions 10-3-M of the signal terminals 10-3 arranged on the first wall portion 10-5-W1 and the mounting portions 10-3-M of the signal terminals 10-3 arranged on the third wall portion 10-5-W3 are also arranged in a zigzag shape. As a result, the mounting pitch does not necessarily have to be the pitch of the signal terminals 10-3 (the mounting pitch is approximately twice the pitch of the signal terminals 10-3), so many signal terminals 10-3 can be placed in a narrow space.

[0060] It can be easily confirmed through the through holes 10 - 5 -PH that the mounting portions 10 - 3 -M of the signal terminals 10 - 3 are arranged in a zigzag shape.

[0061] 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.

[0062] 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

[0076] 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.

[0077] Figure 1 It is a perspective view of an example of a plug connector 10 in the electrical connector according to the present invention.

[0078] In this specification, the electrical connector may be referred to as the plug connector 10, as the case may be, as the case may be, as the case may be, as the case may be, as the case may be, as the case may be, as the case may be, as the case may be, as the case may be, as the case may be, as the case may be, as the case may be, as the case may be, as the case may be, as the case may be, both the plug connector 10 and the receptacle connector (not shown) (or an assembly thereof).

[0079] exist Figure 1 , a fitting 10 - 1 (also referred to as a fitting terminal), a power terminal 10 - 2 , a signal terminal 10 - 3 , and a housing 10 - 5 (a mold portion) of the plug connector 10 are shown as an example.

[0080] The fitting 10-1 is a metal structure for supplementing the strength of the connector 10. The power terminal 10-2 can input / output a power electrical signal. The signal terminal 10-3 can input and output a data signal.

[0081] exist Figure 1 In the embodiment, the hardware 10 - 1 and the power terminal 10 - 2 are manufactured separately.

[0082] In addition, for example, the signal terminal 10-3 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 10 - 3 is 60.

[0083] The housing 10-5 has a base portion 10-5-B. The housing 10-5 has a wall portion protruding from the upper surface of the base portion, and the metal fittings 10-1, power terminals 10-2, signal terminals 10-3, etc. are formed on the wall portion.

[0084] The wall portion is generally formed by four parts, including a first wall portion 10-5-W1, a second wall portion 10-5-W2, a third wall portion 10-5-W3, and a fourth wall portion 10-5-W4. Figure 1As shown, it can be seen that the first wall portion 10-5-W1-the second wall portion 10-5-W2-the third wall portion 10-5-W3-the fourth wall portion 10-5-W4 are connected in the order, and the fourth wall portion 10-5-W4 is connected to the first wall portion 10-5-W1 again. Figure 1 In the figure, the connector is roughly rectangular, the first wall portion 10-5-W1 and the third wall portion 10-5-W3 are side walls, and the second wall portion 10-5-W2 and the fourth wall portion 10-5-W4 are end walls.

[0085] The housing 10-5 (mold part) of the plug connector 10 is preferably made of plastic material, such as liquid crystal polymer (LCP). In addition, the housing 10-5 can be formed of an insulator including resin and epoxy resin, but is not limited to this. The hardware terminals 10-1 and signal terminals 10-3 of the plug connector 10 are preferably made of metal material, although not limited to this, but can also be copper, and the copper alloy can be plated with gold (nickel base).

[0086] It can be seen that the signal terminals 10-3 are arranged in two mixed ways (as an example, the signal terminals 10-3 of one type with the same shape are arranged in two ways by simply changing the direction). Figure 1 In the embodiment, the signal terminals 10-3 run in the length direction (X direction) of the connector 10, and the mounting portions 10-3-M are alternately arranged in a manner of being located once on the outside in the width direction of the connector and once on the inside in the width direction of the connector (seen through the through hole 10-5-PH). In addition, among the multiple mounting portions 10-3-M located on the inside in the width direction (Y direction) of the connector 10, the mounting portions 10-3-M of the signal terminals 10-3-M provided on the first wall portion 10-5-W1 and the signal terminals 10-3-M provided on the third wall portion 10-5-W3 are also arranged in a zigzag shape. Therefore, the mounting pitch is not necessarily the same as the pitch of the signal terminals 10-3 (the mounting pitch is approximately twice the pitch of the signal terminals 10-3), so many signal terminals 10-3 can be placed in a narrow space.

[0087] Figure 2 Observed from below Figure 1 A perspective view of the plug connector 10 is shown.

[0088] Figure 2 Observed from below Figure 1The figure of the plug connector 10 shown in the figure can further confirm the appearance of the hardware 10-1 and the power terminal 10-2 being separated. In particular, it can be seen that in the end wall portion, the mounting portion 10-1-M2 at the substrate (not shown) of the hardware 10-1 is divided into two parts, and the mounting portion 10-2-M of the power terminal 10-2 exists between the two parts. In order to avoid confusion with the first mounting portion 10-1-M1, the second mounting portion 10-1-M2, and the third mounting portion 10-1-M3 of the hardware 10-1, the mounting portion 10-2-M of the power terminal 10-2 (movable terminal) is also referred to as the "connection portion 10-2-M" (of the substrate (not shown)). Of course, the target substrate to which the first mounting portion 10-1-M1, the second mounting portion 10-1-M2, the third mounting portion 10-1-M3 of the hardware 10-1 and the connection portion 10-2-M of the movable terminal 10-2 (power terminal) are installed (connected) is preferably the same substrate.

[0089] There is a second cutout portion 10-CA2 (see below) as a gap between the two second mounting portions 10-1-M2. Figure 3 , Figure 5 , Figure 6 (a) Figure 6 (b)). From another point of view, the second cutout portion 10-CA2 may be formed between one second mounting portion 10-1-M2 to form two second mounting portions 10-1-M2.

[0090] Also, as an example, as described above, the signal terminals 10-3 are one type of signal terminals 10-3 of the same shape, but Figure 2 The situation where only the directions are changed and arranged into two types is better shown in FIG. Although not limited to this, it is observed that Figure 2 , the signal terminals 10-3 run in the length direction (X direction) of the connector 10, and the mounting portions 10-3-M are alternately arranged in a manner of being located once on the outside in the width direction (Y direction) of the connector and once on the inside in the width direction of the connector (seen through the through hole 10-5-PH). In particular, among the plurality of mounting portions 10-3-M located on the inside in the width direction (Y direction) of the connector 10, it can be easily confirmed through the through hole 10-5-PH that the mounting portions 10-3-M of the signal terminal 10-3 provided on the first wall portion 10-5-W1 and the mounting portions 10-3-M of the signal terminal 10-3 provided on the third wall portion 10-5-W3 are arranged in a zigzag shape.

[0091] Figure 3 It is a detailed representation located in Figure 1 Figure 10-1 and the movable terminal 10-2 at the lower left end of the hardware terminal 10-1.

[0092] The fitting terminal 10-1 refers to the fitting 10-1, and the movable terminal 10-2 refers to the power terminal 10-2. The power terminal 10-2 moves in the contact portion 10-2-T (the portion that makes electrical contact with the power terminal of the mating connector (not shown)) and its vicinity, while the fitting 10-1 (fitting terminal) hardly moves. Therefore, it is also called the "movable terminal". As a general name, it is called the fitting terminal 10-1 / movable terminal 10-2. As an example, the fitting terminal 10-1 typically functions as a simple fitting 10-1 that is not powered or does not transmit signals, and the movable terminal 10-2 functions as a powered power terminal 10-2, but it is not necessarily limited to this.

[0093] For ease of explanation, Figure 3 Parts other than the fitting 10-1 and the power terminal 10-2 on one side (the signal terminal 10-3, the housing 10-5 (mold part), the fitting 10-1 and the power terminal 10-2 on the other side, etc.) are omitted.

[0094] exist Figure 3 In the embodiment, the fitting 10-1 (fitting terminal) has a first wall portion 10-5-W1 (refer to Figure 1 ) (especially corresponding to the upper and outer sides thereof) of the first covering portion 10-1-C1, corresponding to the second wall portion 10-5-W2 (refer to Figure 1 ) (especially corresponding to the upper and outer sides thereof) of the second covering portion 10-1-C2, corresponding to the third wall portion 10-5-W3 (refer to Figure 1 ) (especially corresponding to its upper and outer sides) of the third covering portion 10-1-C3.

[0095] The first covering portion 10 - 1 -C1 has a first curved surface 10 - 1 -B1 having a curvature (ie, having a curvature) at an upper portion, and has a first mounting portion 10 - 1 -M1 of a substrate (not shown) at a lower portion.

[0096] Likewise, the third covering portion 10 - 1 -C3 has a third curved surface 10 - 1 -B3 having a curvature at the upper portion, and has a third mounting portion 10 - 1 -M3 of a substrate (not shown) at the lower portion.

[0097] Furthermore, the second covering portion 10-1-C2 has a second curved surface 10-1-B2 having a curvature at the upper portion, and has a second mounting portion 10-1-M2 on a substrate (not shown) at the lower portion, and this second mounting portion 10-1-M2 is divided into two parts, leaving some gaps (second cutting portion 10-CA2) between the two parts, and there is a connecting portion 10-2-M of the power terminal 10-2 (to be described below).

[0098] For reference, the second incision portion 10-CA2 is Figure 3It may also look like "a space between a second mounting portion 10-1-M2 and a connecting portion 10-2-M" and "a space between another second mounting portion 10-1-M2 and a connecting portion 10-2-M", but strictly speaking, Figure 6 (a) Figure 6 As shown in (b), there is a cut space called the second cut portion 10-CA2 between the second mounting portion 10-1-M2, and the connecting portion 10-2-M of the movable terminal 10-2 is positioned in this (cut) space called the second cut portion 10-CA2.

[0099] In addition, there are first inner guides 10-1-G11 and second inner guides 10-1-G12 further inside the first curved surface 10-1-B1 (inside the width direction of the connector), which guide terminals and other components so that a mating connector (not shown) can be easily connected to the plug connector 10.

[0100] Similarly, there are first inner guides 10-1-G31 and second inner guides 10-1-G32 further inside the third curved surface 10-1-B3 (inside the width direction of the connector), which also guide the terminals and other components so that the mating connector (not shown) can be easily connected to the plug connector 10.

[0101] In addition, there is an inner guide portion 10-1-G2 further inside the second curved surface 10-1-B2 (inner in the longitudinal direction of the connector), which also serves to guide components such as terminals so that a mating connector (not shown) can be easily connected to the plug connector 10.

[0102] Figure 4 Yes Figure 3 The figure shows the direction of the hardware terminal 10-1 and the movable terminal 10-2 being reversed.

[0103] Figure 4 Although shown with Figure 3 The same objects are shown again with the directions reversed in order to more clearly show the shapes of other components (such as the power terminal 10 - 2 , etc.).

[0104] with Figure 3 The contents described in the figure are the same as those described in the figure. The first covering portion 10-1-C1 of the fitting 10-1 includes a first curved surface 10-1-B1, a first inner guide portion 10-1-G11, a second inner guide portion 10-1-G12, and a first mounting portion 10-1-M1. In addition, the third covering portion 10-1-C3 of the fitting 10-1 includes a third curved surface 10-1-B3, a first inner guide portion 10-1-G31, a second inner guide portion 10-1-G32, and a third mounting portion 10-1-M3.

[0105] Furthermore, in the second covering portion 10-1-C2 of the hardware 10-1, although its angle is Figure 4 It is not clear, but (refer to Figure 3 ) There is a second curved surface 10-1-B2, an inner guide portion 10-1-G2, and a second mounting portion 10-1-M2.

[0106] Furthermore, it can be observed that the first curved surface 10-1-B1, the second curved surface 10-1-B2, and the third curved surface 10-1-B3 are continuously formed without being cut, which can be achieved by manufacturing the hardware 10-1 by, for example, a stretching process.

[0107] In particular, there is a first outer connecting surface 10-1-D1 between the first curved surface 10-1-B1 and the second curved surface 10-1-B2, forming curved surfaces that are continuous with each other. In particular, there is a second outer connecting surface 10-1-D2 between the second curved surface 10-1-B2 and the third curved surface 10-1-B3, forming curved surfaces that are continuous with each other. This structure is slightly difficult to obtain in the forging process, but can be obtained through the stretching process.

[0108] In addition, Figure 4 In the embodiment, the shape of the power terminal 10-2 can be more easily confirmed. For example, the power terminal 10-2 is separated from the metal fitting 10-1. Of course, although the power terminal 10-2 is not in direct contact with the metal fitting 10-1, Figure 1 , Figure 2 The housing 10 - 5 (mold portion) shown keeps the relative positional relationship between the power terminal 10 - 2 and the fitting 10 - 1 fixed.

[0109] The power terminal 10 - 2 includes a first connection portion 10 - 2 - C1 extending in the width direction of the connector 10 and a second connection portion 10 - 2 - C2 extending from the first connection portion 10 - 2 - C1 in the length direction of the connector 10 .

[0110] There are contact portions 10-2-T on both sides of the first coupling portion 10-2-C1. The contact portions 10-2-T are portions that electrically contact power terminals of a mating connector (not shown).

[0111] One end of the second connection part 10-2-C1 (inward in the length direction of the connector) is connected to the first connection part 10-2-C1, and the other end includes a bent part 10-2-B and a connecting part 10-2-M. The structure of the bent part 10-2-B has an effect of preventing lead from burning.

[0112] Compared to the case where the fitting 10 - 1 (fitting terminal) hardly moves, the power terminal 10 - 2 moves at the contact portion 10 - 2 -T and the vicinity thereof, and therefore is also referred to as a “movable terminal”.

[0113] Figure 5 Observed from below Figure 3 , Figure 4 Figure 10-1 and movable terminal 10-2.

[0114] like Figure 3 , Figure 4 As described above, the first covering portion 10 - 1 - C1 , the second covering portion 10 - 1 - C2 , and the third covering portion 10 - 1 - C3 of the hardware 10 - 1 can be identified.

[0115] In addition, if Figure 4 As described above, the first connecting portion 10-2-C1, the second connecting portion 10-2-C2, the contact portion 10-2-T, the bending portion 10-2-B, and the connecting portion 10-2-M of the power terminal 10-2 (movable terminal) can be confirmed.

[0116] Furthermore, it can be further confirmed that the fitting 10-1 and the power terminal 10-2 are separated. In particular, in the end wall portion, the mounting portion 10-1-M2 at the base plate (not shown) of the fitting 10-1 is divided into two parts, and the connecting portion 10-2-M of the power terminal 10-2 exists between the two parts. There is a cutout portion 10-CA2 as a gap between the mounting portion 10-1-M2 of the fitting 10-1 and the connecting portion 10-2-M of the power terminal 10-2.

[0117] Figure 6 (a) Figure 6 (b) is to facilitate the confirmation of Figures 3 to 5 The figure shows the hardware terminal 10-1 and the movable terminal 10-2 separately.

[0118] The hardware 10 - 1 includes a first covering portion 10 - 1 - C1 , a second covering portion 10 - 1 - C2 , and a third covering portion 10 - 1 - C3 .

[0119] The first covering portion 10 - 1 -C1 of the fitting 10 - 1 includes a first curved surface 10 - 1 -B1 , a first inner guide portion 10 - 1 -G11 , a second inner guide portion 10 - 1 -G12 , and a first mounting portion 10 - 1 -M1 .

[0120] The second covering portion 10 - 1 -C2 of the fitting 10 - 1 has a second curved surface 10 - 1 -B2 , an inner guide portion 10 - 1 -G2 , and a second mounting portion 10 - 1 -M2 (divided into two).

[0121] The third covering portion 10 - 1 -C3 of the fitting 10 - 1 has a third curved surface 10 - 1 -B3 , a first inner guide portion 10 - 1 -G31 , a second inner guide portion 10 - 1 -G32 , and a third mounting portion 10 - 1 -M3 .

[0122] The first curved surface 10 - 1 - B1 , the second curved surface 10 - 1 - B2 , and the third curved surface 10 - 1 - B3 are formed continuously without being cut, which can be achieved by, for example, manufacturing the hardware 10 - 1 using a stretching process.

[0123] The power terminal 10 - 2 includes a first connection portion 10 - 2 - C1 extending in the width direction of the connector 10 , and a second connection portion 10 - 2 - C2 extending from the first connection portion 10 - 2 - C1 in the length direction of the connector 10 .

[0124] There are contact portions 10-2-T on both sides of the first coupling portion 10-2-C1. The contact portions 10-2-T are portions that electrically contact power terminals of a mating connector (not shown).

[0125] One end of the second connection part 10-2-C2 (inner side in the length direction of the connector) is connected to the first connection part 10-2-C1, and the other end has a bent part 10-2-B and a connecting part 10-2-M. The structure of the bent part 10-2-B has an effect of preventing lead from burning.

[0126] Figure 7 Representation and Figure 1 A plug connector 10 (also referred to as 10 ′) according to a different embodiment (second embodiment).

[0127] If Figures 1 to 6 (a) Figure 6 The example shown in (b) is called the first embodiment, and then Figures 7 to 11 The other example shown is called the second embodiment.

[0128] Figure 7 and Figure 1 The shapes of the fitting 10-1 and the power terminal 10-2 are almost the same, but the connection portion 10-2-M of the power terminal 10-2 is different. Figure 1 Located in the second wall portion 10-5-W2 (end wall in the length direction of the connector), but Figure 7 The middle part moves somewhat toward the first wall portion 10-5-W1 (side wall of the connector).

[0129] Although not limited to this, this is not only for Figure 7 The left lower end of the metal fitting 10-1 and the power terminal 10-2, and for Figure 7 The same applies to the fitting 10-1 and the power terminal 10-2 at the upper right end.

[0130] Figure 8 yes Figure 7 A bottom perspective view of another embodiment (second embodiment) of the present invention.

[0131] In addition, although Figure 2 The shapes of the fitting 10-1 and the power terminal 10-2 are almost the same, but the connection portion 10-2-M of the power terminal 10-2 is Figure 2 Located in the second wall portion 10-5-W2 (end wall in the length direction of the connector), but Figure 8 The middle part moves somewhat toward the first wall portion 10-5-W1 (side wall of the connector).

[0132] Although not limited to this, this is not only for Figure 8 The left lower end of the metal fitting 10-1 and the power terminal 10-2, and for Figure 8 The same applies to the fitting 10-1 and the power terminal 10-2 at the upper right end.

[0133] Whether the connection portion 10-2-M is biased toward the right end wall or the left end wall can be changed as needed.

[0134] In addition, there are differences in the following aspects: Figure 2 The installation part 10-1-M2 of the middle hardware 10-1 was divided into two parts. Figure 8 , a mounting portion 10 - 1 - M2 formed of one part is shown.

[0135] Fig. 9 It is a detailed representation located in Figure 7 Figure 10-1 and the movable terminal 10-2 at the lower left end of the hardware terminal 10-1.

[0136] The fitting terminal 10-1 refers to the fitting 10-1, and the movable terminal 10-2 refers to the power terminal 10-2. The power terminal 10-2 moves at the contact portion 10-2-T and its vicinity with respect to the fitting 10-1 (fitting terminal), and is therefore also referred to as a "movable terminal". As a general name, it is referred to as the fitting terminal 10-1 / movable terminal 10-2. For example, the fitting terminal 10-1 typically functions as a simple fitting 10-1 that is not powered or does not transmit signals, and the movable terminal 10-2 functions as a powered power terminal 10-2, but this is not necessarily limited to this.

[0137] For ease of explanation, Fig. 9 Parts other than the fitting 10-1 and the power terminal 10-2 on one side (the signal terminal 10-3, the housing 10-5 (mold part), the fitting 10-1 and the power terminal 10-2 on the other side, etc.) are omitted.

[0138] with Figure 3 Similar to what is described in Fig. 9 In the embodiment, the fitting 10-1 (fitting terminal) has a first wall portion 10-5-W1 (refer to Figure 7) on the upper side and the outer side of the first covering portion 10-1-C1, and the second wall portion 10-5-W2 (refer to Figure 7 ) on the upper side and the outer side of the second covering portion 10-1-C2, and the third wall portion 10-5-W3 (refer to Figure 7 )’s upper and outer sides correspond to the third covering portion 10-1-C3.

[0139] The first covering portion 10-1-C1 has a first curved surface 10-1-B1 with curvature at the upper part, and a first mounting portion 10-1-M1 at the lower part of the substrate (not shown), wherein the first mounting portion 10-1-M1 is divided into two parts, and there is a gap (first cut portion 10-CA1) between the two parts, and there is a connection portion 10-2-M of the power terminal 10-2 (described below). It can be seen that Figure 3 The position in (first embodiment) is slightly different.

[0140] The second covering portion 10 - 1 -C2 has a second curved surface 10 - 1 -B2 having a curvature at the upper portion, and has a second mounting portion 10 - 1 -M2 at the substrate (not shown) at the lower portion.

[0141] Likewise, the third covering portion 10 - 1 -C3 has a third curved surface 10 - 1 -B3 having a curvature at the upper portion, and has a third mounting portion 10 - 1 -M3 at the substrate (not shown) at the lower portion.

[0142] exist Fig. 9 In the embodiment, the cut-out portion 10-CA1 exists in the first mounting portion 10-1-M1, and therefore, the connecting portion 10-2-M (the mounting portion at the substrate (not shown)) of the movable terminal exists on the lower side of the first covering portion 10-1-C1. This is an example, and the following embodiments can also be implemented: the cut-out portion exists in the third mounting portion 10-1-M3, and therefore, the connecting portion 10-2-M (the mounting portion at the substrate (not shown)) of the movable terminal exists on the lower side of the third covering portion 10-1-C3.

[0143] In addition, Figure 3 As in the case of the first embodiment, there are a first inner guide portion 10-1-G11, a second inner guide portion 10-1-G12, an inner guide portion 10-1-G2, a first inner guide portion 10-1-G31, and a second inner guide portion 10-1-G32. This serves to guide components such as terminals so that a mating connector (not shown) can be easily coupled to the plug connector 10.

[0144] Fig.10 Yes Fig. 9 The figure shows the direction of the hardware terminal 10-1 and the movable terminal 10-2 being reversed.

[0145] Fig.10Although shown with Fig. 9 The same objects are shown again with the directions reversed in order to more clearly show the shapes of other components (such as the power terminal 10 - 2 , etc.).

[0146] with Fig. 9 The contents described in the figure are the same as those described in the figure. The first covering portion 10-1-C1 of the fitting 10-1 includes a first curved surface 10-1-B1, a first inner guide portion 10-1-G11, a second inner guide portion 10-1-G12, and a first mounting portion 10-1-M1. In addition, the third covering portion 10-1-C3 of the fitting 10-1 includes a third curved surface 10-1-B3, a first inner guide portion 10-1-G31, a second inner guide portion 10-1-G32, and a third mounting portion 10-1-M3.

[0147] Furthermore, in the second covering portion 10-1-C2 of the hardware 10-1, although its angle is Fig.10 It is not clear, but (refer to Fig. 9 ) There is a second curved surface 10-1-B2, an inner guide portion 10-1-G2, and a second mounting portion 10-1-M2.

[0148] Furthermore, it can be observed that the first curved surface 10 - 1 - B1 , the second curved surface 10 - 1 - B2 , and the third curved surface 10 - 1 - B3 are continuously formed without being cut, which can be achieved by manufacturing the hardware 10 - 1 by, for example, a stretching process.

[0149] In particular, Fig.10 In Fig. 9 It is easier to confirm the shape of the power terminal 10-2. As an example, the power terminal 10-2 is separated from the hardware 10-1. Of course, although the power terminal 10-2 and the hardware 10-1 are not in direct contact, Figure 7 , Figure 8 The housing 10 - 5 (mold portion) shown keeps the relative positional relationship between the power terminal 10 - 2 and the fitting 10 - 1 fixed.

[0150] The power terminal 10-2 has a first connection portion 10-2-C1 and a second connection portion 10-2-C2. The first connection portion 10-2-C1 is elongated in the width direction of the connector 10, and the second connection portion 10-2-C2 is elongated from the first connection portion 10-2-C1 in the length direction of the connector 10 and then elongated in the width direction of the connector 10 (i.e., it is in the form of Shape or shape).

[0151] There are contact portions 10-2-T on both sides of the first coupling portion 10-2-C1. This contact portion 10-2-T is a portion that electrically contacts a power terminal of a mating connector (not shown).

[0152] One end of the second connection portion 10-2-C1 (inward in the length direction of the connector) is connected to the first connection portion 10-2-C1 and bent into The lead is shaped, and then has a bent portion 10-2-B and a connecting portion 10-2-M toward the other end. According to the structure of the bent portion 10-2-B, it has the effect of preventing lead from burning.

[0153] Compared to the case where the fitting 10 - 1 (fitting terminal) hardly moves, the power terminal 10 - 2 moves at the contact portion 10 - 2 -T and its vicinity, and therefore is also referred to as a “movable terminal”.

[0154] Fig.11 Observed from below Fig. 9 , Fig.10 A three-dimensional view of the hardware terminal 10-1 and the movable terminal 10-2.

[0155] like Fig. 9 , Fig.10 As described above, the first covering portion 10 - 1 - C1 , the second covering portion 10 - 1 - C2 , and the third covering portion 10 - 1 - C3 of the hardware 10 - 1 can be identified.

[0156] In addition, if Fig.10 As described above, the first connecting portion 10-2-C1, the second connecting portion 10-2-C2, the contact portion 10-2-T, the bent portion 10-2-B, and the connecting portion 10-2-M of the power terminal 10-2 (movable terminal) can be confirmed.

[0157] Furthermore, the appearance of the metal fitting 10-1 and the power terminal 10-2 being separated can be further confirmed. In particular, in the side wall portion, the mounting portion 10-1-M1 at the substrate (not shown) of the metal fitting 10-1 is divided into two parts, and the connecting portion 10-2-M of the power terminal 10-2 exists between the two parts. There is a cutout portion 10-CA1 (first cutout portion) as a gap between the mounting portion 10-1-M1 of the metal fitting 10-1 and the connecting portion 10-2-M of the power terminal 10-2.

[0158] Of course, the second connection portion may be bent not only toward the first mounting portion 10 - 1 - M1 but also toward the third mounting portion 10 - 1 - M3 .

[0159] exist Figures 1 to 6 (a) Figure 6 The first embodiment shown in (b) and Figures 7 to 11 In the second embodiment shown, the direction (position) of the connection portion 10-2-M of the movable terminal is different and can be appropriately selected according to the circuit pattern formed on the substrate. That is, the degree of freedom of the pattern is increased.

[0160] exist Figures 1 to 6 (a) Figure 6 The first embodiment shown in (b) and Figures 7 to 11 In the second embodiment shown, there is only one connection portion 10-2-M of the movable terminal, but it is not limited to this. Even if they are combined, there are two or more connection portions (for example, (i) one on the second mounting portion 10-1-M2 side, one on the first mounting portion 10-1-M1 side (a total of 2), or (ii) one on the second mounting portion 10-1-M2 side, one on the first mounting portion 10-1-M1 side, and one on the third mounting portion 10-1-M3 side (a total of 3)). In this case, the mounting strength becomes higher and the mounting balance becomes better.

[0161] Fig.12a and Figure 12b Representation and Figures 1 to 6 (a) Figure 6 (b) (first embodiment) and Figures 7 to 11 (Second Embodiment) A connector fitting 100 according to a different comparative example.

[0162] Fig.12a The hardware 100 of the comparative example is different from the first and second embodiments in that the hardware and the power terminal are not separated but formed as one (that is, the hardware also serves as the power terminal). Also, although not limited to this, differences can be observed in the following aspects: Figure 3 , Figure 4 , Fig. 9 , Fig.10 Compared with the case where the first curved surface 10-1-B1, the second curved surface 10-1-B2, and the third curved surface 10-1-B3 are continuously formed without being cut (for example, by a stretching process), in Fig.12a In the comparative example, a cutout portion CA is formed (for example, produced by a forging process).

[0163] Will Fig.12a The hardware 100 of the comparative example is partially unfolded, as shown in FIG. Figure 12b shown.

[0164] Figure 12b Did not Fig.12a The hardware 100 is fully unfolded, and only the part inside the dotted line A (expanded) is unfolded. Assume that the part outside the dotted line A (expanded) is like Fig.12a The same three-dimensional shape.

[0165] From the chronological order of production, it can be understood as Figure 12b The shape is preferred, so that it is partially bent as Fig.12a Before bending Figure 12bThere is a constraint that the guide part 100-G cannot touch the connecting part 100-C in the dotted line B. That is, when unfolded into the unfolded field, the interval of the dotted line B portion becomes narrow, and it becomes impossible to produce or is limited in reducing the width depending on the situation.

[0166] Furthermore, even if it is not necessarily only the guide portion 100-G within the dotted line B, there are also limitations on the manufacturing size of other parts. Figure 12b The expansion pattern does not touch (no expansion field interference), then Figure 12b Proper bending to make Fig.12a Three-dimensional shape.

[0167] Different from this, the connector of the utility model is different from the one using Fig.12a , Figure 12b Compared with connectors with hardware, there is no field interference, so there are fewer constraints on the shape, detailed structure and size of the product. Figure 12b Generally, the constraints when bending a metal sheet to make a hardware (also used as a power terminal) are in the manufacturing process such as Figures 3 to 6 (a) Figure 6 (b) Figures 9 to 11 The hardware 10-1 and power terminal 10-2 shown are greatly reduced.

[0168] Furthermore, it also has the effect of reducing the width of the product (connector). Figure 12b In the manner shown, the minimum width required to manufacture all structures is Figures 3 to 6 (a) Figure 6 (b) Figures 9 to 11 can be further reduced in this way.

[0169] Fig.13 (a), (b), and (c) are diagrams of modified examples of the bending portion 10-2-B.

[0170] exist Figure 6 (a) Figure 6 In (b), the power terminal 10-2 is cut along the CC' line to obtain Fig.13 That is, there is a bent portion 10-2-B that rises from the connecting portion 10-2-C2 and then descends again, and there is a connecting portion 10-2-M that extends from the bent portion 10-2-B. Fig.13As shown in (a), the heights of the connecting portion 10-2-C2 and the connecting portion 10-2-M are almost the same. Of course, even if the bending portion 10-2-B rises and then falls, the present invention is not limited to the case where the heights (the height of the connecting portion 10-2-C2 and the height of the connecting portion 10-2-M) are the same. By making the amount of rise greater or less than the amount of fall, it is also possible to have a bending portion 10-2-B having a different shape than the figure.

[0171] Fig.13 (b) is a diagram showing a bent portion 10-2-B' in which the bent portion is slightly deformed to form a different shape.

[0172] The difference is that the bent portion 10-2-B' does not rise from the connecting portion 10-2-C2' but only (slightly) descends. The mounting portion 10-2-M' extending from the connecting portion 10-2-C2' to form the substrate (not shown) is the same.

[0173] Fig.13 (c) is a diagram of the bending portion 10-2-B" in which the bending portion is deformed into another shape in a different manner.

[0174] The difference is that the bent portion 10-2-B" is not formed by rising from the connecting portion 10-2-C2" but only descending (almost vertically). The mounting portion 10-2-M" extending from the connecting portion 10-2-C2" to form the substrate (not shown) is the same.

[0175] according to Fig.13 (b) and Fig.13 The shape of (c) can also be like Fig.13 The shape of (a) prevents lead from burning. Although not limited to this, Fig.13 In the shape of (a), the lead enters the space where it rises and then falls, which prevents the lead from spreading to other parts unnecessarily. Fig.13 (b) and Fig.13 In the shape of (c), the lead enters the space of the portion where there is a height difference between the connecting portion 10-2-C' or 10-2-C" and the bending portion 10-2-B' or 10-2-B", which can prevent the lead from being unnecessary diffused to other portions.

[0176] However, this is just one example of the effect, and the effects brought about by the configuration of the present invention are of course not limited to this.

[0177] In addition, although Fig.13 The modified examples of (a), (b), and (c) are based on Figure 6 (a) Figure 6 The following description is based on the embodiment (b) of the present invention (first embodiment), but the same principle can also be applied to Figures 9 to 11Embodiment (second embodiment). It can be seen that for the second embodiment, only the case where the second connection portion 10-2-C2 is further bent is considered. Of course, the second connection portion may be bent not only toward the first mounting portion 10-1-M1, but also toward the third mounting portion 10-1-M3.

[0178] In addition, for example, the above-mentioned matters explained with respect to the plug connector 10 can also be applied to a receptacle connector (not shown) (socket connector) within the limit that they are not arranged in nature.

[0179] The embodiments of the present invention are described above with reference to the accompanying drawings, but the present invention is not limited to the embodiments, and can be manufactured in various forms different from each other. It can be understood by those with ordinary knowledge in the technical field to which the present invention belongs that the present invention can be implemented in other specific forms without changing the technical ideas or essential features of the present invention. Therefore, the embodiments described above should be understood as illustrative in all aspects and not restrictive.
