Description

Technical Field

[0001] The utility model relates to an electric connector, and more specifically, to an electric connector in which a mold part comprises a first mold part having a protrusion and a recess, and a second mold part surrounding the first mold part on four sides, for example. 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 may also be referred to as a receptacle connector. Such a plug connector and a socket connector may be formed by arranging terminals in a mold portion. The plug connector and the socket connector may be fastened to each other to form an electrical connector assembly.

[0003] As electronic devices become smaller, it is also true that connectors are required to be smaller and have a lower profile. However, there is a certain degree of limitation in reducing the pitch or making the parts smaller to miniaturize and lower the profile of the connector.

[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 even by a smaller force than before.

[0005] In addition, it is more difficult to produce the desired shape in a mold for manufacturing a miniaturized connector at one time. Also, as the connector is miniaturized, it is becoming increasingly difficult to confirm whether the connector terminals are properly mounted on the substrate or in a state where they can be normally mounted. Utility Model Content

[0085] As an example, in Figure 11 and 2 show a fitting 10 - 1 (which may also serve as a power supply terminal), a signal terminal 10 - 3 , and a housing 10 - 5 (a mold portion) of the plug connector 10 .

[0086] The fitting 10-1 may be a metal structure for supplementing the strength of the connector 10. The fitting 10-1 functions as a power terminal and can input and output power electrical signals. The signal terminal 10-3 can input and output data signals.

[0087] However, this is just an example and is not limited thereto. For example, the fitting 10 - 1 may also serve as a power terminal and may be made of a separate component.

[0088] In addition, for example, the signal terminal 10-3 may be composed of a plurality of pins 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. Figure 1 The number of pins of the middle signal terminal is 36.

[0095] Furthermore, the mounting portion 10-3IM of the signal terminal 10-3I can be recognized through the inspection window 10-IW. Of course, it can also be checked with the naked eye through the inspection window 10-IW, but if the connector 10 of the present invention is a very small connector used in a small electronic device such as a smart phone, for example, it is preferable to use the inspection window 10-IW in order to perform visual confirmation (machine vision) through a camera or other device. Through the inspection window 10-IW, it can be confirmed whether the inner mounting portion 10-3IM is properly installed.

[0096] Figure 3 yes Figure 1 10 is a bottom view of the plug connector 10.

[0102] It can be seen that Figures 1 to 4 The plug connector 10 is reversed upside down (reversed in the Z direction) and Figures 5 to 8 The socket connector 20 is combined with the structure.

[0103] As an example, in Figure 52 shows a fitting 20 - 1 (which may also serve as a power terminal), a signal terminal 20 - 3 , and a housing 20 - 5 (mold portion) of the receptacle connector 20 .

[0104] The hardware 20-1 can be a metal structure used to supplement the strength of the connector 20. The hardware functions as a power terminal and can also input and output power electrical signals. The signal terminal 20-3 can input and output data signals. Figure 1 The hardware 10 - 1 and the signal terminal 10 - 3 of the plug connector 10 are fastened.

[0105] but, Figure 5 The formation and arrangement shown are only examples and are not limited thereto. For example, the fitting 20 - 1 may also be made in a manner that it also serves as a power terminal, or may be made of a separate component.

[0106] In addition, for example, the signal terminal 20-3 may be composed of a plurality of pins 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. Figure 5 The number of pins is 36.

The housing 20-5 has a wall portion protruding from the upper surface of the base portion, and the hardware 20-1, the signal terminal 20-3, etc. are formed on the wall portion. In addition, the housing 20-5 has a center island portion protruding from the upper surface of the base portion. The center island portion, which is a part of the housing 20-5, is partially covered by the hardware 20-1.

[0108] 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 hardware 20-1 and signal terminal 20-3 of the socket connector 20 are preferably made of metal material, although not limited to this, but can also be copper, and the copper alloy can be gold-plated (nickel base).

[0109] The hardware 20 - 1 may also be made of the same or similar material as the signal terminal 20 - 3 .

[0110] Figure 6 yes Figure 5 A front view of the socket connector 20 is shown.

[0113] Furthermore, the mounting portion 20-3IM of the signal terminal 20-3I can be recognized through the inspection window 20-IW. Of course, it can also be checked with the naked eye through the inspection window 20-IW, but if the connector 20 of the utility model is a very small connector used in a small electronic device such as a smart phone, for example, it is preferable to use the inspection window 20-IW in order to perform visual confirmation (machine vision) through a device such as a camera. Through the inspection window 20-IW, it can be confirmed whether the inner mounting portion 20-3IM is properly installed.

[0114] Figure 7 yes Figure 5 1 is a bottom view of the socket connector 20.

[0115] like Figure 5 and Figure 6 As shown in the description, it can be observed that the mounting portion 20-3OM of the signal terminal 20-3O (hereinafter referred to as the outer signal terminal) is arranged on the outer side of the connector 20 (the outer side in the Y direction), and the mounting portion 20-3IM of the signal terminal 20-3I (hereinafter referred to as the inner signal terminal) is arranged on the inner side of the connector 20 (the inner side in the Y direction).

[0116] Figure 8 yes Figure 5 1 is a side view of the socket connector 20.

[0120] The number of pins of the signal terminal 10-3 can be changed as required. Figures 1 to 4 There is no particular difference.

[0121] However, in Fig. 9 In the embodiment, the mold part 10-5 is not formed from a single resin block from the beginning, but is formed twice, that is, the first mold part 10-5-1 is formed by insert molding, and then the second mold part 10-5-2 is formed by insert molding in a shape that partially surrounds the first mold part 10-5-1. In this way, the mold part 10-5 is formed by at least two insert moldings.

[0122] Fig.10 yes Fig. 9 10 is a front view of the plug connector 10.

[0123] exist Fig. 9 As shown in Fig.10 Two types of signal terminals 10-3 are used at the same time, one signal terminal 10-3O is arranged with its mounting portion 10-3OM facing the outside of the connector and the other signal terminal 10-3I is arranged with its mounting portion 10-3IM facing the inside of the connector.

[0125] Furthermore, the mounting portion 10-3IM of the signal terminal 10-3I can be recognized through the inspection window 10-IW. Of course, it can also be checked with the naked eye through the inspection window 10-IW, but if the connector 10 of the utility model is a very small connector used in a small electronic device such as a smart phone, for example, it is preferable to use the inspection window 10-IW in order to perform visual confirmation (machine vision) through a device such as a camera. Through the inspection window 10-IW, it can be confirmed whether the inner mounting portion 10-3IM is installed normally.

[0126] Here, too, by forming the first mold section 10 - 5 - 1 and then forming the second mold section 10 - 5 - 2 on the basis of the first mold section 10 - 5 - 1 , it can be seen that the mold section 10 - 5 is formed as a whole.

[0133] This might look similar to Figure 3 There are differences, but in the present invention, Figures 1 to 4 does not necessarily mean that the mold portion 10-5 is formed by one-time molding and should be regarded as Fig.12 Likewise, the mold section 10 - 5 may be formed by multiple moldings.

[0134] Fig.13 It is a three-dimensional view of another example of a socket connector in the electrical connector according to the present invention.

[0138] However, in Fig.13 In the embodiment, the mold part 20-5 is not formed from one resin block from the beginning, but is formed twice, that is, the first mold part 20-5-1 is formed by insert molding, and then the second mold part 20-5-2 is formed by insert molding in a shape that partially surrounds the first mold part 20-5-1. In this way, the mold part 20-5 is formed by at least two insert moldings.

[0143] Furthermore, the mounting portion 20-3IM of the signal terminal 20-3I can be recognized through the inspection window 20-IW. Of course, it can also be checked with the naked eye through the inspection window 20-IW, but if the connector 20 of the utility model is a very small connector used in a small electronic device such as a smart phone, for example, it is preferable to use the inspection window 20-IW in order to perform visual confirmation (machine vision) through a device such as a camera. Through the inspection window 20-IW, it can be confirmed whether the inner mounting portion 20-3IM is properly installed.

[0144] Here, too, by forming the first mold section 20 - 5 - 1 and then forming the second mold section 20 - 5 - 2 on the basis of the first mold section 20 - 5 - 1 , it can be seen that the mold section 20 - 5 is formed as a whole.

[0145] And, if Fig.14 As shown, a plurality of inspection windows 20-IW are arranged in a zigzag (chidori) shape. When arranged in this way, the pitch is doubled in the installation of the signal terminals. That is, if the pitch between the signal terminals in the length direction of the connector 20 is A, the mounting portion 20-3IM of one signal terminal 20-3I faces the inside of the connector 20, while the mounting portion 20-3OM of another adjacent signal terminal 20-3O faces the outside of the connector 20, so in fact, the pitch between the inner mounting portions 20-3IM is 2A, and the pitch between the outer mounting portions 20-3OM is also 2A.

[0146] In this way, a wider space can be used as the pitch during installation compared to the actual pitch of adjacent terminals. At the same time, due to the presence of a vertical through hole in the height direction (Z direction), namely the inspection window 20-IW, the installation status of the inner mounting part 20-3IM can be easily confirmed by a camera or the like.

[0147] Of course, the zigzag arrangement is one example, and of course slight variations of the arrangement are possible.

[0148] Fig.15 yes Fig.13 3D images of the socket connector 20 at different angles.

[0149] like Fig.13 and Fig.14 As shown in the description, it can be observed that the mounting portion 20-3OM of the signal terminal 20-3O (hereinafter referred to as the outer signal terminal) is arranged on the outer side of the connector 20 (the outer side in the Y direction), and the mounting portion 20-3IM of the signal terminal 20-3I (hereinafter referred to as the inner signal terminal) is arranged on the inner side of the connector 20 (the inner side in the Y direction).

[0150] Here, too, the first mold section 20 - 5 - 1 is formed, and the second mold section 20 - 5 - 2 is formed on the basis of the first mold section 20 - 5 - 1 , so that the mold section 20 - 5 is formed as a whole.

[0151] Fig.16 yes Fig.13 1 is a bottom view of the socket connector 20.

[0152] like Fig.15As shown in the description, it can be observed that the mounting portion 20-3OM of the outer signal terminal 20-3O is arranged on the outer side of the connector 20 (outer side in the Y direction), and the mounting portion 20-3IM of the inner signal terminal 20-3I is arranged on the inner side of the connector 20 (inner side in the Y direction).

[0153] Furthermore, it can be seen that the mold part 20-5 is formed as a whole by forming the first mold part 20-5-1 and then forming the second mold part 20-5-2 on the basis of the first mold part 20-5-1.

[0154] This might look similar to Figure 7 There are differences, but in the present invention, Figures 5 to 8 does not necessarily mean that the mold portion 20-5 is formed by one-time molding and should be regarded as Fig.16 Likewise, the mold section 20 - 5 may be formed by multiple moldings.

[0155] Fig.17 It means in the formation Figures 13 to 16 FIG. 1 is a diagram of a process of manufacturing a socket connector 20 , a preparation step of a signal terminal 20 - 3 and a hardware 20 - 1 .

[0156] As used to make Fig.14 In the first step of the socket connector 20 shown, the signal terminal 20-3 is arranged to be attached to the carrier. Fig.14 , six signal terminals 20 - 3 are arranged in a row in the −Y direction, and six signal terminals 20 - 3 are arranged in a row in the +Y direction.

[0157] exist Fig.17 On the left side, the outer signal terminal 20-3O among the six signal terminals 20-3 is attached to the signal terminal carrier 20-3O-C. In addition, the inner signal terminal 20-3I among the six signal terminals 20-3 is attached to the signal terminal carrier 20-3I-C. This is for example Fig.14 In the diagram, six signal terminals 20 - 3 are arranged in a row in the -Y direction.

[0158] In addition, Fig.17 On the right side of FIG. 2 , it can be seen that the hardware 20 - 1 is prepared in a state of being attached to the hardware carrier 20 - 1 -C.

[0159] Fig.18 It means in the formation Figures 13 to 16 FIG. 2 is a diagram of a process of manufacturing the socket connector 20, wherein the first mold portion 20-5-1 is prepared in a step.

[0160] like Fig.17 As shown on the left side, it can be seen that the first mold part 20-5-1 is formed by the first insert molding in a state where six signal terminals are arranged. Fig.18 In the embodiment, a protrusion 20-5-1P is formed on the left side of the first mold part 20-5-1 and a recess 20-5-1G is formed on the right side of the first mold part 20-5-1. Fig.18 It is not obvious in the figure, but for example, it can be formed by a depression corresponding to the protrusion 20-5-1P.

[0161] Fig.19 It means in the formation Figures 13 to 16 FIG. 2 is a diagram of a process of manufacturing the socket connector 20 , in which a carrier is removed after preparing the first mold part 20 - 5 - 1 .

[0162] Fig.19 and Fig.18 The same, but it can be seen that the carrier 20-3I-C of the inner signal terminal 20-3I is removed. This is to manufacture the layout except Fig.19 There is space for the six signal terminals 20 - 3 in other columns other than the six signal terminals 20 - 3 in one column shown.

[0163] Fig. 20 It means in the formation Figures 13 to 16 FIG. 1 is a diagram of a process of manufacturing the socket connector 20, wherein two first mold parts 20-5-1 are arranged.

[0164] Prepare two Fig.19 The "combination of the first mold part 20-5-1 and the carrier 20-3O-C" is made as shown in Fig. 20 Arrange as shown.

[0165] Fig. 20 The specific shape of the first mold part 20-5-1 shown in FIG. Figure 23 to Figure 24 Described in more detail in .

[0166] Fig.21 It means in the formation Figures 13 to 16 FIG. 1 is a diagram showing the steps of arranging two first mold parts 20 - 5 - 1 and additionally arranging a hardware fitting 20 - 1 in a process of manufacturing a socket connector 20 .

[0167] A protrusion 20-5-1P is formed at one end and a recess 20-5-1G is formed at the other end at the first mold portion 20-5-1.

[0168] exist Fig.21 It can be seen that in Fig. 20 Two additional first hardware 20-1 are arranged beside the two first mold parts 20-5-1. At this time, the first mold part 20-5-1 and the first hardware 20-1 are in a state of being attached with carriers 20-30-C and 20-1-C respectively.

[0169] Fig. 22It means in the formation Figures 13 to 16 FIG. 2 is a diagram showing a step of insert molding the second mold part 20 - 5 - 2 in a process of manufacturing the socket connector 20 , in which the first mold part 20 - 5 - 1 and the hardware 20 - 1 are arranged.

[0170] and Fig.21 In comparison, Fig. 22 As can be seen from the figure, the second mold part 20-5-2 is added. In the process of forming the second mold part 20-5-2 by insert molding, when the ejected resin blends with the protrusion 20-5-1P and the recess 20-5-1G existing in the first mold part 20-5-1, the second mold part 20-5-2 is formed in a state of being strongly combined with the first mold part 20-5-1.

[0171] And, as in Fig. 22 As can be seen in FIG. 2 , the second mold section 20 - 5 - 2 surrounds the first mold section 20 - 5 - 1 on three sides, for example. Fig. 22 As shown, the inspection window 20-IW part has less contact, so it is not necessary to surround the entire three surfaces. In this way, for example, by surrounding the three surfaces, the first mold part 20-5-1 and the second mold part 20-5-2 are more strongly combined.

[0172] Enclosing three faces is one example, for example, Fig.24 As will be described later, it is more preferable to add concave portions 20-5-1G2, 20-5-1G3, and 20-5-1G4 in the longitudinal direction to surround the four surfaces.

[0173] Figures 17 to 22 The present invention is related to the manufacturing steps of the socket connector 20 , but can also be applied to the manufacturing of the plug connector 10 .

[0174] Fig.23 yes Fig. 20 A top view of a specific example of the first mold part 20-5-1 is shown.

[0175] exist Fig.23 Two first mold parts 20-5-1 are arranged in the middle. Fig. 20 The carrier 20-3O-C is shown.

[0176] exist Fig. 20 and Fig.23 , the position of the protrusion 20-5-1P is shown slightly differently, but it is sufficient to have the protrusion 20-5-1P at one end and the recess 20-5-1G at the other end based on the length direction (X direction) of the first mold part 20-5-1. That is, whether the protrusion 20-5-1P is located on the right or left side, the recess 20-5-1G can be on the opposite side. However, depending on the embodiment, the recess 20-5-1G may also be additionally present. For example, observing the later-described Fig. 27As can be seen from the example, one end has a protrusion 20-5-1P and the other end has a recess 20-5-1G, but the presence of another recess 20-5-1G at one end is not excluded.

[0177] And, in Fig. 20 and Fig.23 In the figure, the position of the protrusion 20-5-1P in the Y direction is also shown slightly differently, but it can be slightly biased towards the +Y direction, slightly biased towards the -Y direction, or located in the middle part.

[0178] Fig.24 yes Fig.23 A three-dimensional view of the first mold part 20-5-1 is shown.

[0179] Fig.24 Representation and Fig.23 The same object, but when viewed in a stereoscopic view, it can be seen that additional recesses 20-5-1G2, 20-5-1G3, 20-5-1G4 may also be present.

[0180] If Fig.23 The recess 20-5-1G mentioned in the figure is called the first recess, and it can be called the second recess 20-5-1G2, the third recess 20-5-1G3, the fourth recess 20-5-1G4, etc.

[0181] It can be seen that, in addition to the first recess 20-5-1G, the second to fourth recesses 20-5-1G2, 20-5-1G3, and 20-5-1G4 formed additionally extend in the length direction (Y direction) of the connector 20. In this way, the reason for forming the additional recesses 20-5-1G2, 20-5-1G3, and 20-5-1G4 in the length direction is to form a plurality of recesses in the second insert molding (i.e., from the Fig.21 The state transitions to Fig. 22 In the process of simultaneously forming the second mold portion 20-5-2, the resin solution constituting the second mold portion 20-5-2 is filled in the corresponding recesses 20-5-1G2, 20-5-1G3, and 20-5-1G4.

[0182] Although the resin solution is also filled in the first recess 20-5-1G, the resin solution is also additionally filled and cured in the second to fourth recesses (recesses in the length direction) 20-5-1G2, 20-5-1G3, 20-5-1G4, so that a second mold part that substantially surrounds the first mold part 20-5-1 as a whole (i.e., surrounds the first mold part 20-5-1 on four sides) can be formed. This improves the fastening strength of the first mold part 20-5-1 and the second mold part 20-5-2 and helps to enhance the overall strength of the connector 20.

[0183] For reference, it is not necessary to surround all parts of the four surfaces when surrounding the four surfaces. For example, the part where the inspection window 20-IW is formed may be skipped and surrounded (refer to Fig.16 In addition, Fig.24 In the embodiment, the second concave portion 20-5-1G2 in the longitudinal direction is formed continuously in a row with respect to the entire longitudinal direction, but it is not necessary to form it "entirely" with respect to the longitudinal direction. In addition, even if the second concave portion 20-5-1G2 is composed of two concave portions formed in the longitudinal direction (for example, there is no concave portion in the middle part, etc.). This is also true for the third concave portion 20-5-1G3 and the fourth concave portion 20-5-1G. However, considering strength, etc., the case where it is continuous in the entire longitudinal direction is a preferred example.

[0184] exist Fig.24 In the first mold part 20-5-1, there is one long recess 20-5-1G2 in the outer wall portion, and two long recesses 20-5-1G3 and 20-5-1G4 in the inner wall portion, but the number is not limited. Since the ejection (i.e., the second ejection) in the second insert molding for manufacturing the second mold part 20-5-2 is a recess for good fixation, the required number can be made in consideration of the required strength or size, etc. However, if there is at least one on the inner wall and at least one on the outer wall, a certain degree of fixing force can be provided. The pattern of the second ejection filling the outer wall recess 20-5-1G2 can be Fig.13 , Fig.15 Waiting for confirmation.

[0185] For reference, Figures 17 to 24 The illustration is about the receptacle connector 20 , but the plug connector 10 can also be made using basically the same principles.

[0186] Fig.25 Another example of the plug connector 10 according to the present invention is shown.

[0187] This is similar to Figure 2 It is similar to that shown in , but it can be seen that a plurality of mounting portions 10-3IM are exposed in one inspection window 10-IW instead of having one mounting portion in one inspection window 10-IW.

[0188] For reference, it is also possible to assume that all the inner mounting parts 10-3IM are included in one inspection window 10-IW, but in this case, the strength of the connector 10 is weakened, so it is not preferred. The reason is that there is a high possibility that various problems in use may occur, such as the part of the mold part supporting the signal terminal array arranged in the longitudinal direction (X direction) may be bent.

[0189] Therefore, if Fig.25As shown, it is preferable to set one inspection window 10-IW in one signal terminal column and another inspection window 10-IW in another signal terminal column. However, this is not limited to this. For example, by using other methods, it is also possible to have one inspection window 10-IW for every two or three signal terminals 10-3.

[0190] in addition, Fig.25 The mold portion 10 - 5 shown may also be formed by multiple insert molding (for example, by a first mold portion 10 - 5 - 1 and a second mold portion 10 - 5 - 2 ).

[0191] Fig.26 Another example of the receptacle connector 20 according to the present invention is shown.

[0192] Fig.26 is with Fig.25 The plug connector 10 corresponds to the socket connector 20 .

[0193] Fig.26 and Figure 6 The socket connector 20 shown in FIG. 1 is similar to the socket connector 20 shown in FIG. 1 , but it can be seen that a plurality of mounting portions 20 - 3IM are exposed in one inspection window 20 -IW instead of having one mounting portion in one inspection window 20 -IW.

[0194] Fig.26 The mold portion 20 - 5 shown may also be formed by multiple insert molding (eg, by a first mold portion and a second mold portion).

[0195] Fig. 27 Another example of the first mold part 20 - 5 - 1 according to the present invention is shown.

[0196] Fig. 27 and Fig.24 Generally similar, but the main differences are as follows.

[0197] exist Fig.24 In the embodiment, the second recesses 20-5-1G2 are connected to form one in the length direction of the connector. Fig.24 The same is true for the third recess 20-5-1G3 and the fourth recess 20-5-1G4.

[0198] On the contrary, in the example showing the modification Fig. 27 It can be observed that the second recess 20-5-1G2 is not formed as one connected in the longitudinal direction of the connector, but is formed as a plurality of separated ones in the longitudinal direction. Fig. 27 The second concave portions 20-5-1G2 are shown as 7, but are not limited thereto, and generally, any number of concave portions 20-5-1G2 is sufficient. Fig. 27In the embodiment, the third recess 20-5-1G3 and the fourth recess 20-5-1G4 are also divided into a plurality of portions along the length direction of the connector.

[0199] Furthermore, it is sufficient as long as one end has a protrusion 20-5-1P and the other end has a recess 20-5-1G. Fig. 27 As shown, it can be seen that except for the protrusion 20-5-1P ( Fig. 27 The protrusion on the upper right side of the upper part) and the concave part 20-5-1G ( Fig. 27 In addition to the concave portion on the left side of the upper part), it is not ruled out that there are other concave portions 20-5-1G ( Fig. 27 the concave part on the upper right side).

[0200] 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, and those with ordinary knowledge in the technical field to which the present invention belongs can understand that the technical concept or essential features of the present invention can be implemented in other specific forms without changing them. Therefore, the embodiments described above should be understood as illustrative in all aspects and not restrictive.
