Patent Description:
An electronic device such as a smartphone may include a housing which forms the exterior of the electronic device. The housing of the electronic device may be commonly made of a metal or plastic material. For example, a part of the housing may be made of a metal member to protect the exterior of the electronic device, and another part of the housing may be made of a plastic member to reduce weight and to facilitate manufacturing.

In addition, the housing of the electronic device may include a metal material so as to implement an aesthetic appearance, and may include a plastic material such that the metal material part may be partially used as an antenna of the electronic device.

Document <CIT> describes a composite housing for electronic devices, emphasizing a seamless integration of different materials, such as metals and polymers. It focuses on structural improvements, particularly the side members connecting the front and rear plates of the device.

In general, an electronic device may include an exterior housing made of a metal material having a higher specific gravity or density, such as titanium or steel use stainless (SUS), than normal metal materials. If such a metal material having a higher specific gravity or density is used, the amount of raw material used per the same volume may increase, and the cost for manufacturing the electronic device may increase.

In addition, the metal material such as titanium or stainless steel has a higher specific gravity or density than other metal materials and may thus increase the weight of the electronic device, and is difficult to process, thereby increasing the time and cost to fabricate the housing.

In addition, the electronic device may include a housing which has a heterojunction of a metal having a high specific gravity or density (for example, titanium or stainless steel) and a metal having a low specific gravity or density (for example, magnesium or aluminum). However, the housing having a heterojunction may be difficult to obtain by a method such as welding due to a difference in melting point between the metal materials, and the junction surface may widen or bend due to a difference in thermal expansion coefficient when the housing is fabricated by a diecasting process.

In other words, according to an embodiment, the first conductive material and the third conductive material <NUM> may be fixed in a coupled state by the injection-molded insulator <NUM>.

According to an embodiment, as the first coupling structure <NUM> is formed in the concave-convex structure, the middle member <NUM> and the outer member <NUM> are connected to each other without an additional connection member.

According to an embodiment, the insulator <NUM> of the middle member <NUM> may correspond to a material for adhering the outer member <NUM> and the middle member <NUM> and/or the inner member <NUM> and the middle member <NUM>.

For example, the first coupling structure <NUM> formed between the first conductive material of the outer member <NUM> and the third conductive material <NUM> of the middle member <NUM> may be adhered by being surrounded by the insulator <NUM>. According to an embodiment, the second coupling structure <NUM> formed between the second conductive material of the inner member <NUM> and the third conductive material <NUM> of the middle member <NUM> may be adhered by being surrounded by the insulator <NUM>.

<FIG> is a partial perspective view illustrating a coupling structure of an inner member and a middle member of an electronic device according to various embodiments.

Referring to <FIG>, the outer member <NUM> may be connected to the middle member <NUM> while having the first coupling structure <NUM>, and the inner member <NUM> may be connected to the middle member <NUM> while having the second coupling structure <NUM>.

According to an embodiment, the inner member <NUM> may be coupled to the third conductive material <NUM> of the middle member <NUM>. For example, the inner member <NUM> may form a protrusion <NUM> and the third conductive material <NUM> of the middle member <NUM> may form a hall <NUM>. According to an embodiment, the inner member <NUM> may be coupled to the middle member <NUM> by inserting the protrusion <NUM> of the inner member <NUM> into the hall <NUM> of the third conductive material <NUM>.

According to an embodiment, the electronic device <NUM> may form the second coupling structure <NUM> by including an additional connection member in a state in which the inner member <NUM> and the middle member <NUM> are coupled to each other. For example, the additional connection member may correspond to a welding material.

For example, the first conductive material of the outer member <NUM> may have a melting point of a first temperature, and the second conductive material of the inner member <NUM> may have a melting point of a second temperature. According to an embodiment, the third conductive material <NUM> of the middle member <NUM> may have a melting point of a third temperature.

According to an embodiment, the first conductive material of the outer member <NUM> may correspond to a material having a melting point substantially different from that of the second conductive material of the inner member <NUM>. According to an embodiment, the second conductive material of the inner member <NUM> may correspond to a conductive material having a melting point different from that of the first conductive material <NUM> of the middle member <NUM> within a first range.

According to an embodiment, the melting point of the first temperature of the first conductive material may have a temperature higher than that the melting point of the second temperature of the second conductive material.

According to an embodiment, the melting point of the third temperature of the third conductive material <NUM> may have a difference from the melting point of the second temperature of the second conductive material within a first range.

According to an embodiment, as the melting point of the first temperature and the melting point of the second temperature have different temperatures, it may be substantially difficult that the first conductive material of the outer member <NUM> and the second conductive material of the inner member <NUM> are electrically connected to each other by welding. For example, in case that there is a difference between the melting point of the first temperature and the melting point of the second temperature, a bubble may be generated in a welding region of the second conductive material of the inner member <NUM> having a lower melting point and thus an adhesion defect between the first conductive material of the outer member <NUM> and the second conductive material of the inner member <NUM> may occur.

Meanwhile, according to an embodiment, as the melting point of the second temperature and the melting point of the third temperature have a difference within a first range, the second conductive material of the inner member <NUM> may be electrically connected to the third conductive material <NUM> of the middle member <NUM> by welding.

However, the second coupling structure <NUM> formed between the inner member <NUM> and the middle member <NUM> is not limited to the welding.

For example, the electronic device <NUM> may transmit and/or receive a signal in a designated frequency, based on an electrical path including the second coupling structure <NUM> configured to electrically connect the inner member <NUM> and the middle member <NUM>.

For example, the first point <NUM> may correspond to a point in which the second coupling structure <NUM> is formed, by which the second conductive material of the inner member <NUM> and the third conductive material <NUM> of the middle member <NUM> in <FIG> are connected to each other.

According to an embodiment, the first point <NUM> may be formed at <NUM> to <NUM> points inside the electronic device <NUM>, but is not limited thereto. For example, the first point <NUM> may be formed at more than <NUM> points. The first point <NUM> may be formed at less than <NUM> points.

According to an embodiment, the electronic device <NUM> may include a PCB (<NUM> in <FIG>) disposed in a space at which the inner member <NUM> is formed, and a ground (not shown) and a wireless communication circuit (not shown) may be disposed on the PCB <NUM>.

For example, the third conductive material <NUM> of the middle member <NUM> may be electrically connected to the ground of the PCB <NUM> disposed on the inner member <NUM> through the first point <NUM>.

According to an embodiment, the multiple conductive materials inside the electronic device <NUM> may be electrically connected to the wireless communication circuit in the PCB <NUM>. For example, the third conductive material <NUM> of the middle member <NUM> may be electrically connected to the wireless communication circuit of the PCB <NUM> through a second point <NUM>. By way of example, the second point <NUM> may correspond to a point in which the PCB <NUM> is directly connected to the middle member <NUM> while not connected to the inner member <NUM> or the outer member <NUM>.

According to an embodiment, using the third conductive material <NUM> electrically connected to the outer member <NUM> being electrically connected to the PCB <NUM>, the electronic device <NUM> may use the outer member <NUM> and the third conductive material <NUM> of the middle member <NUM> as an antenna.

According to an embodiment, the electronic device <NUM> may transmit and/or receive a signal in a designated frequency using the first point <NUM> in which the middle member <NUM> and the inner member <NUM> are connected to each other and the second point <NUM> in which the middle member <NUM> and the PCB <NUM> are connected to each other.

For example, the second conductive material of the inner member <NUM> may directly face the insulator <NUM> of the middle member <NUM> and may be formed inside the electronic device <NUM>. In addition, according to an embodiment, the insulator <NUM> of the middle member <NUM> and the third conductive material <NUM> of the middle member <NUM> may directly face each other and may be formed inside the electronic device <NUM>.

According to an embodiment, a surface where the inner member <NUM> and the middle member <NUM> are in contact and a surface where the middle member <NUM> and the each configuration are in contact may be formed to have a predetermined inclination.

For example, a first interface <NUM> wherein the second conductive material of the inner member <NUM> and the insulator <NUM> of the middle member <NUM> are in contact may be formed to be slanted having a first angle θ1 with reference to a first axis (e.g., the z-axis). Accoding to an embodiment, a second interface <NUM> wherein the insulator <NUM> of the middle member <NUM> and the third conductive material <NUM> of the middle member <NUM> are in contact may be formed to be slanted having a second angle θ2 with reference to the first axis (e.g., the z-axis).

According to an embodiment, the first angle θ1 formed by the first interface <NUM> and/or the second angle θ2 formed by the second interface <NUM> may be formed within a range of -<NUM> degrees to +<NUM> degrees. For example, the first angle θ1 formed by the first interface <NUM> and/or the second angle θ2 formed by the second interface <NUM> may be +<NUM> degrees. For another example, the first angle θ1 formed by the first interface <NUM> and/or the second angle θ2 formed by the second interface <NUM> may be -<NUM> degrees.

However, the first angle θ1 and the second angle θ2 are described as -<NUM> degrees to +<NUM> degrees, but are not limited thereto. For example, the first angle θ1 may be formed to be about <NUM> degrees or less, and the second angle θ2 may be formed to be about <NUM> degrees or more.

According to an embodiment, as the first interface <NUM> is formed to be slanted by the first angle θ1 and/or the second interface <NUM> is formed to be slanted by the second angle θ2, the manufacturing difficulty of the electronic device <NUM> may be reduced compared to a case in which the first interface <NUM> and/or the second interface <NUM> is not formed to be slanted. For example, in case that the first interface <NUM> is formed to be slanted by the first angle θ1 and/or the second interface <NUM> is formed to be slanted by the second angle θ2, the inner member <NUM> and the middle member <NUM> may be easily taken out in a process of being manufactured by a diecasting method compared to a case in which the first interface <NUM> and/or the second interface <NUM> is not formed to be slanted.
