An electrical connector (20) includes: a mold part (20-5), a power terminal (20-1), and a plurality of terminals (20-3). The power supply terminal (20-1) includes: a first wall portion (20-1-W1) formed on the end side in the longitudinal direction of the electrical connector and joined to the first wall portion; a second end wall portion (20-1-W2) formed on one end side in the width direction of the electrical connector and joined to the second wall portion; and a third end wall portion (20-1-W3) formed on the other end side in the width direction of the electric connector and joined to the fourth wall portion, and an open hole (H) formed at the intermediate lower end of the first end wall portion (20-1-W1).

Description

Electric connector
Technical Field
The present utility model relates to an electrical connector. More particularly, the present utility model relates to an open hole for a power terminal.
Background
Generally, in the case where substrates are connected to each other, two connectors connected to each substrate by a method such as soldering (welding) are used, and the two connectors may be connected to each other. Here, one of the two connectors is a plug connector (plug connector), and the other is a socket connector (socket connector). The receptacle connector may also be referred to as a receptacle (receptacle) connector. Such plug and receptacle connectors may be formed by arranging terminals at the mold portions. The plug connector and the receptacle connector may be secured to one another to form an electrical connector assembly.
With the trend of miniaturization of electronic devices, miniaturization and low-profile of connectors are a trend. However, there is a limit to some extent in reducing the pitch or making parts smaller to miniaturize and lower the back of the connector in practice.
On the other hand, there is also an aspect in that it is difficult to secure durability of the connector as compared with the prior art while the connector is miniaturized. The reason is that the components are easily broken or deformed even with smaller forces than before.
In addition, as one of the deformations, if the metal terminals are kept in a specific shape at all times during the bonding between connectors or in a state of having been bonded, plastic deformation may occur. The term "plastic deformation" as an inverse of elastic deformation means a state in which deformation is maintained without returning to the original pattern of the material even when the load applied to the material is removed. The reason for this is that all materials are typically elastic but deform the pattern when stress is generated. There is also a need for terminals of connectors that are progressively finer to prevent such plastic deformation.
In addition, there is a case where a resin mold (housing) of the connector is manufactured by insert molding, and in this case, whether the housing is molded as it is determined according to the fluidity of the resin, and therefore there is also a necessity to improve the fluidity of the resin.

Detailed Description
Advantages and features of the present utility model, methods of accomplishing the same, and the like, will become apparent by reference to the accompanying drawings and the embodiments described in detail. However, the present utility model is not limited to the embodiments disclosed below, but is implemented in various forms different from each other, and the embodiments are provided only for the purpose of fully completing the disclosure of the present utility model and fully conveying the scope of the present utility model to those having ordinary skill in the art to which the present utility model pertains, and the present utility model is defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.
Fig. 1 is a view showing an example of a plug connector in an electrical connector according to the present utility model.
In fig. 1, a power terminal (10-1), a signal terminal (10-3), and a housing (10-5) of a plug connector (10) and a mold part are shown as an example.
The power supply terminal (10-1) may be a metal structure for supplementing the strength of the connector (10), and may be capable of inputting and outputting a power supply electric signal. The signal terminal (10-3) is capable of inputting and outputting a data signal.
However, this is an example and is not limited thereto. For example, the power terminal (10-1) may also be made separately from the power terminal by a separate fitting.
In addition, for example, the signal terminal (10-3) may be composed of four PINs (PINs) which allow a current of 0.3A, and may be a terminal which allows a current exceeding 0.3A, for example, 5A, to function as a power supply terminal. However, the number of pins is four as an example.
The housing (10-5) has a base portion. The housing (10-5) has a wall portion protruding from the upper surface of the base portion, and a power supply terminal (10-1), a signal terminal (10-3), and the like are formed in the wall portion.
The housing (10-5; the mould part) of the plug connector (10) is preferably of plastics material, for example liquid crystal polymer (Liquid Crystal Polymer, LCP). The case (10-5) may be formed of an insulator including a resin, an epoxy resin, or the like, but is not limited thereto. The power supply terminal (10-1) and the signal terminal (10-3) of the plug connector (10) are preferably made of metal, but not limited thereto, may be made of copper, for example, and may be gold-plated (nickel-plated) with a copper alloy.
Fig. 2 is a diagram illustrating a portion of fig. 1.
In fig. 2, a first protrusion (F1), a second protrusion (F2), a third protrusion (F3), and the same plane part (F4) are shown, all of which are part of the housing (10-5).
Fig. 2 shows a lower end (G) which is a part of the power supply terminal (10-1).
Fig. 3 is a view showing a part of fig. 2 in further enlarged form.
Fig. 3 shows a first projection (F1), a second projection (F2), a third projection (F3), and the same plane portion (F4), which are the same as fig. 2, but are also denoted as F1 (10-5), F2 (10-5), F3 (10-5), and F4 (10-5) in the meaning of being part of the housing (10-5). Hereinafter, it will be understood that the first protruding portion (F1) and the first protruding portion (F1 (10-5)) refer to the same object.
Fig. 3 shows a lower end portion (G) which is similar to fig. 2, but is also denoted as G (10-1) in the meaning of being a part of the power supply terminal (10-1). Hereinafter, it will be understood that the lower end (G) and the lower end (G (10-1)) refer to the same objects.
The first protrusion (F1), the second protrusion (F2), and the third protrusion (F3) form the bottom of the housing (10-5), and are not necessarily, but are, for example, the same height as each other. The same height means that reference to the Z-axis on the figure is considered.
On the other hand, the same plane part (F4) is formed lower than the first protruding part (F1). The lower end (G) of the power terminal (10-1) is formed at the same height as the same plane (F4). That is, the lower end portion (G) has the same height as the same plane portion (F4), and the first protruding portion (F1), the second protruding portion (F2), and the third protruding portion (F3) are formed higher than the lower end portion (G) and the same plane portion (F4).
Typically, (i) the lower end portion (G) and the same plane portion (F4) are the same height, (ii) the first protrusion (F1), the second protrusion (F2), and the third protrusion (F3) are higher than the lower end portion (G) and the same plane portion (F4), and (iii) the first protrusion (F1), the second protrusion (F2), and the third protrusion (F3) are the same height as each other. However, the conditions under (iii) are preferable, but not required. As an example, the following structure may be used: only the second protruding part (F2) and the third protruding part (F3) are higher than the lower end part (G) (precisely the upper surface of the lower end part) of the power terminal (10-1), and the first protruding part (F1) is at the same height as the lower end part (G).
Specifically, in the lower end portion (G), the housing (10-5) has: a second protruding part (F2) which is connected to the lower end part on one side of the electric connector (10) in the width direction and on the outer side of the electric connector (10) in the length direction, has a step difference with the upper surface of the lower end part (G), and is formed to be high; and a third protruding part (F3) which is connected to the lower end part (G) on the other side of the width direction of the electric connector (10) and the outer side of the length direction of the electric connector (10), has a step difference with the upper surface of the lower end part (G), and is formed to be high.
The reason why the structure is as described in (i) to (iii) (or (i), (ii)) is to form a gap so as not to directly contact with the upper surface of the power terminal of the mating connector (20) as described below with reference to fig. 5 and the like.
On the other hand, fig. 3 shows a first extension (E1) and a second extension (E2) of a terminal movable piece as a power supply terminal (10-1). Further, the third extension (E3) (outer extension) is shown extending toward both ends of the power supply terminal (10-1) in the connector longitudinal direction.
Specifically, the power supply terminal (10-1) has: a lower end (G); a first extension (E1) that extends upward from one side in the width direction of the electrical connector (10) in the lower end (G); a second extension (E2) extending upward from the other side of the electric connector (10) in the width direction in the lower end (G); and a third extension (E3) extending upward from the outer side of the electric connector (10) in the length direction in the lower end (G).
Fig. 4 is a view in which the power supply terminal (10-1) in fig. 3 is omitted.
In order to more clearly show the content illustrated in fig. 3, the power supply terminal (10-1) is omitted from fig. 4. Of course, the lower end portion (G) which is a part of the power supply terminal (10-1) is omitted.
Although fig. 3 also shows the first projecting portion (F1) and the same plane portion (F4), the step difference between the first projecting portion (F1) and the same plane portion (F4) can be confirmed in fig. 4. The first protruding part (F1) is higher and the same plane part (F4) is lower based on the Z-axis direction.
Fig. 5 is a diagram showing a state in which the plug connector (10) is coupled with the receptacle connector (20) as a counterpart connector.
Fig. 5 shows the situation of cutting along the AA line shown in fig. 3.
Unlike fig. 1 to 4, fig. 5 shows a state in which the plug connector (10) is coupled to the mating connector (20; receptacle connector (receptacle connector)) after being turned upside down in the Z-axis direction.
In fig. 5, the lower end (G) of the power terminal (10-1) of the plug connector (10) is opposite to the upper end of the power terminal (20-1) of the mating connector (20), but is spaced apart with a space (D). The reason for forming such a space (D) is that (not shown in fig. 5 itself but shown) the protruding portions (F1, F2, F3) of the housing (10-5) of fig. 3, 4 are in contact with the power supply terminal (20-1) of the counterpart connector (20) and/or the housing (20-5). That is, the protruding portions (F1, F2, F3) of the housing (10-5) of the plug connector (10) are in contact with the power supply terminal (20-1) of the mating connector (20) and/or the housing (20-5), but the interval (D) is generated because the lower end portion (G) of the power supply terminal (10-1) of the plug connector (10) is formed lower than the protruding portions (F1, F2, F3) (in the direction of the-Z axis in FIGS. 3, 4, and the plug connector (10) is turned upside down so as to be in the direction of the +Z axis in FIG. 5).
In other words, such a space (D) is not a space of such an extent that it is unavoidable even after the coupling between connectors, but a space due to intentional formation of a step (height difference) between the "protruding portion (F1, F2, F3)" and the "same plane portion (F4) and the lower end portion (G)".
For reference, fig. 5 shows a case where the power terminal (10-1) of the plug connector (10) overlaps with a part of the power terminal (20-1) of the receptacle connector (20), but this is for convenience of illustration, and is not actually overlapped, and the first extension (E1) and the second extension (E2) of the terminal movable piece, which are annular shapes of the power terminal (10-1) in fig. 5, are bent sideways in the width direction.
On the other hand, fig. 5 shows two avoidance portions (S) denoted as S. The avoidance part (S) is a space for the end parts of the extension parts (E1, E2) to move to accommodate the end parts of the extension parts (E1, E2) when the extension parts (E1, E2) bend to the outer sides in the width direction. In fig. 5, the corresponding avoidance portion (S) faces a part of the case (10-5; the mold portion) to the outside in the width direction, and faces the first extension portion (E1) or the second extension portion (E2) to the inside in the width direction.
Fig. 6 is a view showing a state of cutting along the BB line shown in fig. 3.
Unlike fig. 1 to 4, fig. 6 also shows a state in which the plug connector (10) is coupled to the mating connector (20; receptacle connector (receptacle connector)) after being turned upside down in the Z-axis direction. Which is also the same as in the case of fig. 5.
In fig. 6, the lower end (G) of the power terminal (10-1) of the plug connector (10) is opposite to the upper end of the power terminal (20-1) of the mating connector (20), but is spaced apart with a space (D). The reason for forming such a space (D) is that the protruding parts (F1, F2, F3) of the housing (10-5) are in contact with the power supply terminal (20-1) of the mating connector (20) and/or the housing (20-5). That is, the protruding portions (F1, F2, F3) of the housing (10-5) of the plug connector (10) are in contact with the power supply terminal (20-1) of the mating connector (20) and/or the housing (20-5), but the interval (D) is generated because the lower end portion (G) of the power supply terminal (10-1) of the plug connector (10) is formed lower than the protruding portions (F1, F2, F3) (in the Z-axis direction in FIGS. 3, 4, and in the +Z-axis direction in FIG. 6 where the plug connector (10) is turned upside down.
In other words, such a space (D) is not a space of such an extent that it is unavoidable even after the coupling between connectors, but a space due to intentional formation of a step (height difference) between the "protruding portion (F1, F2, F3)" and the "same plane portion (F4) and the lower end portion (G)".
As can be seen from fig. 3 to 6, a step is formed between the lower end portion (G) of the power supply terminal (10-1) (to be precise, the upper surface of the lower end portion) and the other surfaces (F1, F2, F3) of the housing (10-5). Therefore, the step is not in direct contact with the upper surface of the power terminal (20-1) and forms a space (D) when being combined with the mating connector (20). Further, a portion of the same plane portion (F4) that is in contact with the power supply terminal (10-1) is rounded to be further closely supported by the power supply terminal (10-1) so as to prevent the power supply terminal (10-1) from coming off.
By such a space (D), plastic deformation of the power supply terminal (10-1) is prevented. At the same time, plastic deformation of the power supply terminal (20-1) of the mating connector (20) is prevented.
The protruding portions (F1, F2, F3) are preferably all higher than the lower end portion (G), but there may be an embodiment in which only the protruding portions (F2, F3) are higher than the lower end portion (G). On the other hand, the same plane portion F4 is preferably at the same height as the lower end portion G of the power terminal 10-1 and the upper surface thereof.
As described above, the interval (D) is generated when the plug connector (10) and the mating connector (20) are coupled (fitted).
The lower end portion (G) of the power terminal (10-1) of the plug connector (10) itself is in contact with the power terminal (20-1) of the mating connector (20), but another portion of the power terminal (10-1) is in contact with the housing (20-1) of the mating connector (20) and/or the power terminal (20-1) depending on its position. Similarly, the upper surface of the power terminal (20-1) of the mating connector (20) is in contact with the housing (10-5) of the plug connector (10).
The same plane portion (F4), the second protruding portion (F2), and the third protruding portion (F3) are preferably processed in a curved shape when viewed from above. This is to be supported in close contact with the power supply terminal (10-1). For example, if it is a right angle pattern instead of a curve, the adhesion is lowered and thus may be easily dropped.
Fig. 7 is a diagram showing a receptacle connector (20; receptacle connector) according to the present utility model.
The receptacle connector (20) is a mating connector from the perspective of the plug connector (10). Of course, the plug connector (10) is a mating connector from the perspective of the receptacle connector (20).
The receptacle connector (20) of fig. 7 is fitted to the plug connector (10) shown in fig. 1 to be coupled. Of course, in order to perform such coupling, the plug connector (10) of fig. 1 is turned upside down and fitted with the receptacle connector (20) of fig. 7, or the receptacle connector (20) of fig. 7 is turned upside down and fitted with the plug connector (10) of fig. 1.
Fig. 7 shows, as an example, a power terminal (20-1), a signal terminal (20-3), and a housing (20-5) of the receptacle connector (20), and a mold portion.
The power supply terminal (20-1) may be a metal structure for supplementing the strength of the connector (20), and may input and output a power supply electric signal. Of course, the power supply terminal (20-1) may be separated into a separate hardware and power supply terminal. The signal terminal (20-3) is capable of inputting and outputting a data signal. Which are fastened to the power supply terminal (10-1) and the signal terminal (10-3) of the plug connector (10) of fig. 1, respectively.
However, the formation and arrangement shown in fig. 7 is an example and is not limited thereto. For example, the hardware (20-1) may be formed separately from the power supply terminal (20-1).
In addition, for example, the signal terminal (20-3) may be composed of four pins which allow a current of 0.3A, and may be a terminal which allows a current exceeding 0.3A, for example, 5A, to function as a power supply terminal. However, the number of pins is four as an example.
The housing (20-5) has a base portion. The housing (20-5) has a wall portion protruding from the upper surface of the base portion, and a power supply terminal (20-1), a signal terminal (20-3), and the like are formed in the wall portion. In addition, the housing (20-5) has a central island (center island portion) (20-5I) protruding from the upper surface of the base portion. A portion of this central island (20-5I) as part of the housing (20-5) is covered by the power supply terminal (20-1).
The housing (20-5; the mould part) of the receptacle connector (20) is preferably of plastics material, for example liquid crystal polymer (Liquid Crystal Polymer, LCP). The case (20-5) may be formed of an insulator including a resin, an epoxy resin, or the like, but is not limited thereto. The power supply terminal (20-1) and the signal terminal (20-3) of the receptacle connector (20) are preferably made of metal, but not limited thereto, and may be made of copper, for example, and gold plating (nickel under layer) may be performed on copper alloy.
The power terminal (20-1) may be formed of separate hardware and power terminals, and the hardware may be made of the same or similar material as the power terminal (20-1) and the signal terminal (20-3).
Fig. 8 is a view schematically showing the case (20-5) removed in fig. 7.
By removing the housing (20-5), the structure and arrangement relationship of the metal power supply terminal (20-1) and the signal terminal (20-3) can be made clearer.
In particular, an extension portion (20-1E) of a part of the power supply terminal (20-1) extending in the longitudinal direction (X direction) of the connector (20) covers a part of the central island portion (20-5I) (see FIG. 7).
On the right side of the extension (20-1E) in the figure, an additional extension for reinforcing strength in case of a long connector (20) is shown.
Fig. 9 is a perspective view of the power terminal (20-1) of the receptacle connector (20).
The power supply terminal (20-1) shown in fig. 9 is formed by deep drawing (deep drawing).
The deep drawing process is also called deep shrinkage process, and is a process of forming a container-like product having a seamless space bottom surface by closely adhering an outer peripheral portion of a plate to an inner side by a punch (punch) and a die (dies) in the press process of a plate material. In the machining, since the flange portion may be deformed by a compressive force in the circumferential direction, the material may be machined while being suppressed by the deformation suppressing plate. The present utility model relates to a method for processing a product molded from an iron-metal plate into a seamless bowl or barrel pattern by using a die and a punch, and is widely used for small-sized parts such as electric parts to large-sized parts such as a body of an automobile or a main body of an airplane.
For example, if the power terminal (20-1) is manufactured by deep drawing, the power terminal (20-1) may be manufactured in a shape as shown in fig. 9, for example, with a smooth bent portion (20-1B).
However, if the deep drawing method is not applied, but the sheet material is simply cut and bent, the shape like the bent portion (20-1B) cannot be formed, and only the shape in which both the cut portion and the bent portion are exposed like the extension portion (20-1E) shown in fig. 9 can be formed. (of course, this means that, as shown in FIG. 8, the extension portion (20-1E) is a part of the power terminal (20-1), but for convenience of explanation, and if the deep drawing method is not used, the bent portions (20-1B) on the right and left sides in the width direction of the power terminal (20-1) of FIG. 9 cannot be formed into a circle, and as in the extension portion (20-1E) should be cut open.) it is easy to know that the rigidity and elasticity of the whole of the power terminal (20-1) are weakened, assuming that the bent portion (20-1B) cannot be formed as in FIG. 9 and should be cut open.
However, if the metal plate is processed by deep drawing, there is a slight limitation in forming the resin housing (20-5) between the electrical connectors (20). That is, after the power supply terminal (20-1) is manufactured, the resin is flowed in and solidified in a state where the metal power supply terminal (20-1) and the signal terminal (20-3) are arranged at the position suitable for the mold according to insert molding, so that the corresponding resin becomes the housing (20-5), but if the power supply terminal (20-1) manufactured by the deep drawing method has no cut portion or the cut portion is small, the inlet into which the resin is to be injected is limited. For example, if the bent portion (20-1B) is a cut portion unlike fig. 9, the resin can be easily injected with the corresponding cut portion, but this is not the case in the same structure as fig. 9.
In order to solve such a problem, an open hole (H) is formed in the center portion of the end wall of fig. 9 in the power supply terminal (20-1) of the electrical connector (20) according to the present utility model.
In fig. 9, the power supply terminal (20-1) is enlarged to have three end wall portions. The connector comprises a first end wall part (20-1-W1) formed on the end part side in the length direction of the connector (20), a second end wall part (20-1-W2) formed on the two end parts side in the width direction of the connector (20), and a third end wall part (20-1-W3).
The first end wall portion (20-1-W1), the second end wall portion (20-1-W2), and the third end wall portion (20-1-W3) of the power supply terminal (20-1) correspond to the positions of the first wall portion (W1), the second wall portion (W2), and the fourth wall portion (W4) of the housing (20-5) of fig. 10, which will be described later, respectively.
Of these, the open hole (H) is preferably formed in the first end wall portion (20-1-W1). Further, it is preferable that the first end wall portion (20-1-W1) is formed at a middle lower end (i.e., a middle in the left-right direction (Y direction), a lower end in the up-down direction (Z direction)). It is considered that, when the power supply terminal (20-1) manufactured by deep drawing is used for insert molding at the time of forming at this position, the resin is injected through the corresponding open hole (H), and the corresponding resin uniformly spreads sideways around the open hole as the center.
Assuming that the open hole (H) is located at the first end wall portion (20-1-W1) not at the position shown in fig. 9 but rather at the right or left side, the resin injected for insert molding (to be later referred to as the case (20-5)) is highly likely to spread unevenly.
On the other hand, in fig. 9, the second end wall portion (20-1-W2) and the third end wall portion (20-1-W3) are not formed with open holes (H). The reason for this is that it is considered that if the open hole is in the second end wall portion (20-1-W2) and/or the third end wall portion (20-1-W3), it is difficult to uniformly inject the resin in bilateral symmetry (based on the width direction).
Fig. 10 is an enlarged view of a part of fig. 7, and is a view of the additional housing (20-5) of fig. 9.
The result of insert molding the power supply terminal (20-1) of fig. 9 (and the signal terminal (20-3), not shown) is shown in fig. 10.
After insert molding, the housing (20-5; a resin mold) covers a part of the open hole (H). The reason for this is that it is not necessary to continue to open the corresponding open holes (H) after the injection of the resin is completed. Moreover, the overall strength of the housing (20-5) can be increased only by covering the corresponding portions.
The embodiments of the present utility model have been described with reference to the above drawings, but the present utility model is not limited to the embodiments, and can be manufactured in various forms different from each other, and it will be understood by those skilled in the art to which the present utility model pertains that the present utility model can be implemented in other specific forms without changing the technical ideas or essential features of the present utility model. The above described embodiments are, therefore, to be considered in all respects only as illustrative and not restrictive.
