Description

Internal combination of phone accessories {INNER ASSEMBLY OF MOBILE PHONE ACCESSORIES}

The present invention relates to an internal assembly of a mobile phone accessory, and more particularly, an electrical connection between an LED (Light Emitting Diode) and a mobile phone input / output connector (IO connector), which is easy to carry for an accessory and emits light in case of emergency, without soldering. To an internal combination of mobile phone accessories.

Accessories for mobile phones typically include dedicated and portable chargers, wired and wireless earphones (necklaces, wire telescopic), hands-free kits (talkers), talking couplings, light emitting antennas and accessories that operate on call connection, various dolls, and cross-stitch mobile phone straps. It is leading the new trend of mobile phones with numerous ideas and cute character goods such as mobile phone cover, mobile phone ringtone player, hidden camera detection accessories and so on.

In particular, these products have a novel design that harmonizes with mobile phones, and some of them combine functionality to entertain mobile phone users.

Functional accessories include battery chargers, dancing dolls that work when the call is connected, and removable LED lights on the phones.

Mobile phone equipped with a removable LED lamp according to the prior art, as disclosed in the Republic of Korea Utility Model Registration No. 261265 in 2002, a separate high-intensity light-emitting semiconductor (LED) in the earphone connector that is already mounted on the upper side of the conventional mobile phone ) It is designed to connect and use the lamp. It is a flashlight function that can be used in emergency. It can be used immediately in case of emergency. It can be used immediately by simply connecting to the earphone connector of the mobile phone currently used without any complicated device or equipment.

However, in the conventional mobile phone, the user has a disadvantage in that it is easy to lose as it is a small item with the inconvenience of having to separately carry a detachable LED lamp.

In addition, since the conventional LED lamp inserts its earphone connector into the earphone connection socket, the light is relatively weak because the earphone operating voltage is used, and the part where the earphone connection socket is connected is not an exclusive circuit for power supply but an audio circuit. Therefore, there is a disadvantage in that an overload of the circuit may damage the audio circuit as a result.

In addition, even when a conventional LED lamp is connected to a cell phone string using a string, since the connection terminal of the earphone connector and the like look ugly, it does not match the design of the cell phone at all, thus losing its function as an accessory.

Therefore, in consideration of these problems, the applicant filed a dual application on February 5, 2003, as a mobile phone accessory patent and utility model, and filed a PCT application.

As shown in FIG. 1, the mobile phone accessory 20 according to the present applicant has a high-brightness LED (I) on an input / output connector 40 having an 18-pin, 22-pin, and 24-pin standard structure conforming to the technical standard of a conventional mobile phone 10. By connecting 30), the light source can be emitted from the battery mounted on the mobile phone 10 in a dark place or a place where there is no light at night can be used as a flashlight replacement.

The connection terminal of the input / output connector 30 of the mobile phone accessory 20 is detachably connected to the input / output socket provided in the groove formed at the bottom of the mobile phone 10.

Since the mobile phone accessory 20 receives battery power directly according to the connection, the mobile phone 10 can emit powerful lights while minimizing the electrical load on the internal circuit of the mobile phone 10, and has a streamlined design and various colors. It is kept in the cases (21, 27) and easy to carry, has attracted the spotlight as a high quality accessory product that can harmonize with the mobile phone (10).

The following problems were found during the mass production of these small products.

That is, the LED 30 has a device characteristic that light is generated when a lead wire having a relatively long length is a positive electrode (+), a lead wire having a short length is a cathode (−), and a current flows in a forward direction.

However, due to the characteristics of a small product, it is very inconvenient to connect the respective lead wires of the LED and the input / output connector to the same internal mounting space, and the assembly work is very difficult.

In other words, in order to connect the same polarity of the lead wires with the LED and I / O connectors facing each other in a narrow internal mounting space, lead wire cutting and soldering is required to cut different lengths of LED lead wires to the same length beforehand. Work must be involved.

However, the assembling worker does not easily check the polarity of the LED after the cutting of the lead wires with the naked eye, and the defect rate continues because soldering is performed based on his memory.

In order to solve the above problems, the present invention provides an input / output connector having lead wires of different lengths and various types of lead wires that are bent and formed with holes, such that LEDs and input / output connectors face horizontally without cutting and soldering lead wires. The purpose of the present invention is to provide an internal combination of mobile phone accessories that can maintain a stable electrical connection and simplify the assembly work of mobile phone accessories.

In addition, another object of the present invention is to provide an internal combination of the mobile phone accessories that can be firmly fixed when the removable input coupled to the input and output socket provided in the groove formed on the bottom of the mobile phone by providing a link-type spring.

The mobile phone accessory 20 has an outer body case 27 that forms an LED hole 28 so that the light emitting head (part) of the LED 30 can protrude to the outside, and a ring to which the mobile phone strap 23 is connected. It has the cover case 21 which has a fixed end so that 22 may be fastened.

The insertion end 21 a of the cover case 21 is fitted into the insertion hole 29 of the body case 27, and is fitted with an LED 30, an input / output connector 40, and a first inner body part 24. ), The link spring 25, the second inner body 26 provides a space to be coupled.

The link spring 25 is a kind of locking member, and is bent and formed from a material of high elastic wire.

The link spring 25 is bent downward at both ends of the intermediate portion 25a to be closer to the 'c' shape, and then, both sides of the wire bent to the 'b' shape, respectively, based on the side shape. 25b and 25c are formed, and the protruding bending end 25d similar to the semicircle ring shape is integrally formed at each end thereof.

The link spring 25 is coupled to wrap the upper and both sides of the input and output connector 30 along the bending direction of the wire, both sides thereof to firmly secure the input and output connector 30 to the input and output socket of the mobile phone 10. An elastic force is generated at the protruding bent end 25.

The first inner body portion 24 and the second inner body portion 26 are coupled in the vertical direction to partially wrap the LED 30, the input / output connector 40, the link-type spring 25 coupled as described above, One assembly module 50 is made. The assembly module 50 is mounted to the inside of the outer body case 27 through the insertion hole 29 by a fixing means such as an adhesive or an interference fit method.

In this case, the light emitting head of the LED 30 protrudes to the outside through the LED hole 28, the connection terminal 49 of the input / output connector 40 in the opposite direction to the outside of the insertion hole 29 It protrudes as much as it can be inserted into the input / output socket of 10).

The cover case 21 and the body case 27 are assembled as one small accessory product when the insertion end 21a is fastened to the insertion hole 29.

As shown in FIG. 3, the LEDs 30 extend in the axial direction inside the light emitting heads where light is output, respectively, and have a relatively short length of the anode LED lead wires 31 having a relatively long length. The cathode LEDless line 32 is provided.

The anode LED lead wire 31 and the cathode LEDless wire 32 are formed of a conductive material having an elastic force of a predetermined size.

The anode LED lead wire 31 has a first supporting jaw 33a which protrudes slightly in both side directions at the center of its length, and similarly, the second supporting jaw 33b is also formed in the cathode LEDless wire 32. . The first and second supporting jaws 33a and 33b of the lead wires 31 and 32 serve as stoppers for maintaining a constant height between the LED 30 and the printed circuit board (PCB).

The anode LED lead wire 31 of the LED 30 provided in the present invention has a 'b' shaped tip portion 35 that is bent in a direction perpendicular to the longitudinal direction, and has the same shape as the cathode LEDless wire 32. Of the tip portion 34 is bent.

The input / output connector 40 corresponding thereto is molded to have the positive connector lead wire 41 and the negative connector lead wire 42 having different lengths in a straight line so that the LED 30 and the input / output connector 40 are horizontally and facing each other. Is produced in a way.

That is, the positive connector lead wire 41 is short in length, and the negative connector lead wire 42 is long in length. These connector lead wires 41 and 42 are formed of an energizing material having an elastic force of a predetermined size.

The short length of the positive electrode connector lead wire 41 is eccentric from the side of the input / output connector 40 corresponding to the long length of the positive electrode LED lead wire 31 by a predetermined distance h downward from the axis of the input / output connector 40. It is physically fixed at the position and is connected to the connecting terminal 49 so as to electrically conduct the positive pole DC power supply.

The long negative electrode lead wire 42 is eccentric in the same manner as the positive electrode connector lead wire 41 and is physically and electrically coupled to the corresponding place of the short negative electrode LED lead wire 32.

In particular, the other end of the positive electrode connector lead wire 41 and the negative electrode connector lead wire 42 has ring portions 44 and 45 formed with holes having a predetermined inner diameter.

As in the hook method, the tip portion 35 of the positive LED lead wire 31 is inserted into the hole of the ring portion 45 of the positive electrode connector lead wire 41, and the ring portion 44 of the negative electrode connector lead wire 42 and the negative electrode in the same manner. The tip portion 34 of the LED lead wire 32 is inserted to maintain the electrical contact relationship with each other.

Meaning that the length and length of the connector lead wires 41 and 42 of the input / output connector 40 and the LED lead wires 31 and 32 of the LED 30 correspond to each other means that the anode LED lead wire 31 having the longer lead wire length is The sum of the lengths of the LED-connected wires 31 and 41 coupled to the positive lead wire lead 41 having the shorter lead wire length, and the negative lead wire lead 42 with the negative lead LED wire 32 having the shorter lead wire length are longer. ) Means that the sum of the lengths of the LED-connected wires 32 and 42 is equal to each other. As a result, the input / output connector 40 and the LED 30 can be disposed to face each other.

In addition, a plurality of protrusions 48 are formed on the upper surface of the input / output connector 40, and the protrusions 48 are formed on the inner surface of the first inner body portion 24 to have a larger volume corresponding to the spring diameter. When coupled to the recessed groove 24a, it serves to support and fix the linked spring 25 interposed in the remaining empty space (see FIG. 5).

Accordingly, the axial direction of the LED 30 and the input / output connector 40 coincides with the assembly reference line c.

As mentioned above, the positive connector lead wire 41 and the negative connector lead wire 42 are fixed eccentrically from the shaft center of the input / output connector 40, and the tip portions 34 and 35 of the LED lead wires 31 and 32 are connected to the connector. Due to the relationship that is constrained to the ring portions 44 and 45 of the lead wires 41 and 42, respectively, bending deformation occurs slightly within the limits of the elastic limit, so that the restoring force f corresponding to the elastic force is generated by the lead wire 31. 32, 41, 42) to make the mutual contact relationship more confidential.

Accordingly, in the present invention, the lead wires 31 and 32 of the LED 30 and the lead wires 41 and 42 of the input / output connector 40 can be hermetically and electrically connected to each other without soldering, and can be easily and quickly. Assembly work can be performed.
