Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In the description of the present disclosure, it is to be understood that the terms "center", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships used when the terminal is used.
Liquid sealing at the terminal opening or slot has been a difficult point in seal design, for example: side keys, a headset hole, and a USB (Universal Serial Bus) hole, etc. Wherein, to the sealed design of keyway department of installation side key on the center, can adopt silica gel stopper or contact pin (also called pin needle) formula structure, block up liquid such as external environment's water and get into in the center from side key installation department. However, the pin needle scheme has great process difficulty and high cost. As shown in fig. 1, in the silicone plug sealing scheme, the silicone plug 20 is located on the side of the baffle 12 of the middle frame 10, the silicone plug 20 leaves an avoiding channel 21 for the wires 30, and liquid in the external environment easily flows through the avoiding channel 21 along the direction of an arrow, and enters the main board compartment 11 near the central area of the middle frame 10 along the routing path of the wires 30, so that a gap of corrosion or short circuit is caused to the main board devices, and the sealing effect is still not ideal. In order to further improve the sealing effect at the position of the side key, the following technical scheme is provided in the disclosure.
Referring to fig. 2 and 3, an embodiment of the present disclosure provides a side key structure of a mobile terminal, including:
a middle frame 110, the middle frame 110 having a side key mounting groove 114 and a baffle plate 112 formed to be upwardly protruded, the baffle plate being adjacent to the side key mounting groove 114;
a conductive line 200 of the side key circuit, extending from a first surface of the blocking plate 112 to a second surface through an end surface, wherein the first surface is a surface of the blocking plate 112 close to the side key installation groove 114, the second surface is a surface of the blocking plate 112 far away from the side key installation groove 114, and the end surface is a surface connected between the first surface and the second surface;
and an elastic sealing member extending at least from a first surface of the baffle 112 to an end surface of the baffle 112, wherein a liquid seal is formed at the first surface and the end surface of the baffle 112 through which the lead 200 passes.
In the embodiments of the present disclosure, "liquid-tight" generally refers to a seal that can at least restrict a gap where liquid such as water passes through the wire, but is not limited to only being able to seal the liquid.
The elastic sealing element can be made of elastic rubber materials. Such as silica gel.
Without limitation, the conducting wire of the side key circuit can pass through the elastic sealing element and the baffle plate, and after the liquid seal is formed, at least no gap exists between the elastic sealing element and the conducting wire and between the conducting wire and the baffle plate. Alternatively, the wire may also pass through the elastic sealing element, and at least no gap is formed between the elastic sealing element and the wire and between the elastic sealing element and the baffle.
The lead of the side key circuit can be a wiring harness or a flat cable. For example, the side key circuit lead is a flexible and foldable cord such as a PI (Polyimide) cord or an LCP (Liquid Crystal Polymer) cord. The wiring harness may contain one or more flexible wires.
For another example, the side key Circuit lead is a Flexible Printed Circuit (FPC) cable. The sealing can be more simply and conveniently formed by adopting the FPC wiring mode.
The bezel 112 is positioned adjacent to the side key mounting slots 114, and typically the side key mounting slots 114 are located on the outside of the bezel 112. The proximity setting includes: the blocking plate is spaced apart from the side key mounting groove or, as shown in fig. 3, the blocking plate 112 forms a portion of the wall of the side key mounting groove 114.
In the embodiment of the disclosure, the elastic sealing element is distributed along the wire routing path, and when the elastic sealing element is compressed, the elastic sealing element can be in close contact with the baffle plate so as to fill gaps where dust, water and the like easily pass in the wire routing path, and prevent the water, the dust and the like from entering the middle frame from the gaps where the wires pass. In contrast, the first surface of the baffle is farther away from the center of the middle frame, and the second surface is closer to the center of the middle frame, so that if the sealing effect is not ideal, liquid or dust in the external environment can firstly enter the main board bin of the middle frame from the first surface of the baffle, through the end face of the baffle, and then through the second surface of the baffle. The elastic sealing elements are respectively in close contact with the first surface and the end face of the baffle plate and respectively form liquid seal, even if the liquid seal effect of the elastic sealing elements on the first surface is not ideal enough, the liquid seal of the elastic sealing elements and the end face can further prevent liquid, dust and the like from continuously entering the middle frame, and the multiple liquid seal mode is formed at different positions of the wiring path of the lead, so that the sealing stability and the sealing effect of the elastic sealing elements are further improved; the risk of corrosion or short circuit of the main board device in the middle frame is reduced.
In other alternative embodiments, the resilient seal comprises:
a first seal 120;
a second seal 160 located between the first seal 120 and the baffle 112;
the second sealing member 160 covers the end face and at least part of the first surface of the baffle plate 112 in a bending manner;
the surface of the second sealing member 160 facing the first sealing member 120 has a first receiving groove, and the conducting wire extends from the first surface of the baffle plate to a second surface through the end face along the first receiving groove;
the first and second seals cooperate to form a fluid tight seal at the first surface and the end face of the baffle through which the wire passes.
The first sealing element and the second sealing element can be pressed against each other to form a tight contact, so that a liquid seal can be formed better.
Referring to fig. 2 to 4, since both the first and second seals 120 and 160 have elasticity, both upper and lower surfaces of the wire 200 are better protected by the elastic seal when passing between the first and second seals 120 and 160. After the elastic sealing member is compressed, the gap where the lead wire 200 passes through disappears, thereby performing a liquid sealing function.
In a particular example, the first seal and the second seal are two physically separable, split pieces. When the device is installed, the second sealing element can be covered on the baffle in a bending mode, wherein the lead is placed in the first accommodating groove, and then the first sealing element is covered on the lead, so that the first sealing element is embedded in the first accommodating groove. As shown in fig. 4, the second seal 160 at the bottom cooperates with the baffle 112 to fill the gap between the wire 200 and the baffle 112 and form a fluid-tight seal at the bottom of the wire 200. The first seal 120 at the top is fitted with the second seal 160, and there is no gap between the first seal 120 and the lead 200, and between the second seal 160 and the lead 200. In addition, the first sealing member 120 may also be fitted into the battery cover to fill a gap between the lead wire 200 and the battery cover plate when the terminal is integrally assembled. Therefore, no gap is left at the passing part of the lead 200, and the sealing effect on the lead 200 is improved.
In a non-limiting manner, the width of the part of the wire, which is located in the first accommodating groove, is less than or equal to the width of the first accommodating groove, so that the wire is ensured not to be exposed out of the first accommodating groove, and the wire is bent when the terminal is assembled, and the damage to the wire is further reduced.
In a specific example, the first sealing element and the second sealing element may also be a one-piece structure, for example, two ends of the first sealing element and the second sealing element are connected, a gap is formed in a middle portion between the two ends, a wire may pass through the gap, after a subsequent wire passes through the gap, the two ends of the elastic sealing element may be pinched to exert force on a center of the elastic sealing element, and a middle portion of the one-piece elastic sealing element may be opened to facilitate insertion of the wire. The integral structure can reduce the installation process of the elastic sealing element.
The first receiving groove may be only located on a portion of the surface of the second sealing member 160 facing the first sealing member 120, or may be located on the entire surface of the second sealing member 160 facing away from the baffle 112, as shown in fig. 5, two sides of the entire surface of the second sealing member 160 facing away from the baffle 112 are arched to form a first receiving groove 161, and the first receiving groove 161 receives the conductive wire 200, so as to limit the conductive wire 200 from being separated, and suppress the conductive wire 200 from moving relative to the elastic sealing member.
The second seal member passes the end face of the baffle plate at least from the first surface of the baffle plate, so that when the second seal member is compressed, the second seal member can form liquid seal at least at the first surface and at the end face of the baffle plate respectively. The second seal 160 is illustratively shown in fig. 3 and 5 as extending from the first surface of the baffle 112, past the end surface of the baffle 112, and to the second surface of the baffle 112.
In other alternative embodiments, the second seal is U-shaped; the second sealing member covers the baffle plate through the U-shaped opening toward the end surface.
As shown in fig. 3 and 5, a fixing groove 162 is formed at a side of the second sealing member 160 facing the barrier 112, the fixing groove 162 is formed to match the barrier 112 in shape, and the width of the fixing groove 162 may be equal to or slightly less than the thickness of the barrier 112 so that the second sealing member 160 is firmly fixed to the barrier 112. Fig. 5 exemplarily shows that the second sealing member 160 formed with the fixing groove 162 has a U-shape, and it is understood that the second sealing member 160 may have other shapes.
In practical applications, the second sealing member 160 may be made of a material with specific elasticity, for example, the second sealing member 160 is a rubber member. The width of the fixing groove 162 is slightly smaller than the thickness of the baffle 112, so that when the second sealing member 160 is installed on the baffle 112, the baffle 112 can be in interference fit with the fixing groove 162, and this installation mode is favorable for enhancing the connection strength between the second sealing member 160 and the baffle 112.
In other alternative embodiments, the second seal 160 is bonded to the baffle 112. The bonding may further strengthen the connection between the second seal 160 and the baffle 112.
In a specific example, an adhesive layer is arranged between the second sealing element and the baffle plate, and the second sealing element covers the baffle plate by using the structure of the second sealing element, so that the reliability of connection of the second sealing element and the middle frame is further improved by the adhesive layer.
The adhesive layer may be formed by curing an adhesive or may be a double-sided tape.
In other alternative embodiments, the elastomeric seal further comprises: sealing the ribs;
the sealing rib is arranged on the first sealing element and protrudes towards the inside of the first accommodating groove; the sealing rib is matched with the second sealing element to form liquid seal at the position where the lead passes through; and/or the presence of a gas in the atmosphere,
the sealing rib is arranged on the second sealing element and is positioned in the first accommodating groove; the sealing rib is matched with the first sealing element to form liquid seal at the position where the lead passes through.
In practical application, under the effect of the pressing force of the battery cover, the sealing rib further increases the contact pressure between the elastic sealing element and the lead, namely, the sealing rib can press the lead more tightly relative to the first sealing element, so that the lead is contacted with the elastic sealing element more tightly, and the sealing effect of the elastic sealing element is further enhanced.
When the sealing rib 140 is disposed on the first sealing member 120, as shown in fig. 4, the sealing rib 140 and the first sealing member 120 may be of a one-piece structure. For example: the plastic can be molded or machined integrally.
When the sealing rib is arranged on the second sealing element, the sealing rib and the second sealing element can be of a one-piece structure. For example: the plastic can be integrally formed by molding or machining.
