[New content] There are ▲ creators, in view of the above The problem and the missing are the collection of relevant materials. After the evaluation and consideration of the evening party, and the many years of experience accumulated from the miscellaneous trips, the design and the modification of the card connector were designed. The main purpose of the creation is that the fourteen pins of the conductive terminal set are respectively arranged on the base, and the other five are placed on the base, and the arrangement is arranged, and the money is shot-supported. The length of the pin is longer than the length of the other four pins. When the pin is pushed, the grounding point on the memory card and the pin with the grounding circuit can be preferentially connected first. The secret circuit can be used at the contact point. Side by side Acupuncture, through the _ long_ column of each terminal and the chronograph card contact terminal _ sequence, can simplify the use of Xuan, in order to reduce the assembly and working hours, the problem of preferentially forming a ground loop. Ways: In order to achieve the above objectives and effects, the technical means and structure used in this creation, we have a complete understanding of the characteristics of this creation and the characteristics and miscellaneous ^ ^ Lee fully understand. The first, second and third figures are composed of the card joints of the author's creation M336594; among them, the exploded view and the partial combination map, it can be clearly seen from the figure that the connector is made of insulating seat 1. Conductive terminal group 2 and transition strips 3 The insulating base body i has a pedestal u, a wire == an empty portion 15', and a top portion of the base 13 is formed for storage. 匕 "Thinking the space of the valley. The conductive terminal group 2 has fourteen pins, the forest pins have a flat soldering portion 2 i, and the remote adapter portion 2 i (4) has a contact portion 2 2 ' wherein the second pin is to the second Ten pins (number Μ 2 to A1 〇) are provided in the pedestal 11 'Asian ambassadors are set on the pedestal ii The contact portion 2 2 of the inner pin extends toward the base 13 and the first pin, the tenth pin to the fourteenth pin (numbered as a hole, A 1 1~A; [4) is set in The base portion i 3 and the contact portion 2 2 of the pin disposed in the base u extend toward the base 11 to form a relative arrangement of the pin structure. The pushing device 3 is disposed in the insulating base 1 One side of the arm 丄 2 is provided for the preset memory card to be pressed by the second-cycle (four), and the pushing device 3 has a sliding seat 31' and is formed inside the sliding seat 31-side. The guide rod 3 3 q moves the position of the guide groove 3 2 ' away from the guide groove 3 2 and the other side is provided with a pushing portion for the memory card to push 3 4 'and the sliding seat 3丄 and the base 1 i Connected;; elastic element 3 5. 10 M336594 Therefore, when the creation is assembled, the fourteen pins of the conductive terminal group 2 are respectively placed in the base ii and the base i 3 of the base 1 so that the contact portions of the pins 2 2 They are all located at the hollow portion 丄5 of the insulating base i and extend toward the accommodating space 丄6 to form a mechanical pick-up structure, and the turning device 3 is assembled to the inner side arm of the insulating base body 1! 2, the upper end of the element 3 5 is respectively abutted on the 'month shifting seat 3 1 and the end surface of the base 1 1 ' and the guide rod 3 end is fixed on the arm 1 2 'the other end is positioned on the sliding seat 31 In the guide groove 3 2 , finally, the shielding case 4 is covered on the insulating seat block, and the shielding case 4 is pressed on the guide bar 3 3 to complete the overall assembly of the present invention. Please also refer to the third, fourth and fifth riding instructions. This is the partial combination drawing of the creation, the specification of the memory card contacts, and the description of the pins and connectors. It can be clearly seen from the figure that the card of this creation The connector mainly uses the memory card 5 of the MMS Pr〇-Hg 〇uo specification. In response to the large capacity and high transmission efficiency, the contact point on the memory card 5 is inevitably increased, so as shown in the fourth and fifth figures. For the ten contacts (pinl~piniQ) on the original MS memory card 5, add the direct four points (Pinll~pinl4), so it will be renewed at the D ΑΤΑ Pin (Pin3~pin5, pin7) of the material. Add four side-by-side data pins (Pinll~Pini4); in addition, the Memory Card Association specification points out that when the memory card 5 is inserted into the card connector, the entire electronic device is ineffective or even permanent due to the sudden strong surge. Damage, so the vss Pin (pini 〇) on the memory card 5 must be contacted with the ground terminal in the card connector (ie, the first pin Ai or the tenth port 11 M336594 ί « pin A 1〇) to form a ground. The circuit can continue to communicate with other terminals for data transmission. Therefore, four signal transmission terminals (ie, the tenth pin A 1 1 to the fourteenth pin A 14) are added to the card connector of the present invention, and are arranged side by side in opposite directions, but in order to cope with The V § s P i η specified in the Memory Card Association specification requires a 'priority contact' problem. Therefore, the arrangement position of the first pin A 1 is changed, so that the first pin A 1 having the ground loop function is disposed on the base 13 At the same time, the length of the first pin • A 1 is designed to be shorter. When the memory card is inserted, the SSP i η of the memory card 5 is preferentially brought into contact with the first pin A; [form a ground loop, and then After sequentially contacting the other pins 'the needle 5 insertion position, the fine terminal (ie, the sixth pin A 6) contacts the pin 6 contact on the memory card 5 to check whether the memory card 5 is pushed in. In place 'can only transfer data in the memory card. Therefore, when the memory card 5 is pushed in by the accommodating space χ 6, the sliding portion 31 of the slip _ seat 31 is first touched, and then the sliding seat 31 is displaced backward, so that the sliding seat 31 can be driven. The guide rod 3 3 slides in the guide groove 3 2 when the memory card 5 is fully seated: the rear guide rod 3 3 is positioned in the guide groove 32 and the elastic member 35 is in a compressed state. Further, the contacts of the memory card 5 and the contact portion 2 of the f-terminal group 2 are electrically connected to each other to transmit data; if the memory is to be withdrawn, the memory card 5 only needs to be pressed again to make the positioning state When the guide rod 3 3 slides again, the elastic restoring force of the three elements 35 can cause the sliding portion of the sliding seat 3 i to be 2 out of the card 5 to exit the insulating seat 1 , so the present invention The device 3 can be used to pass the memory card 5 twice to make the guide rod 3 3 in the guide groove 3 2 to generate a cycle of 12 M336594 slip and grain action, but this part is not the creation of this The focus is on this, so only a brief description is given in this manual for understanding. In order to prevent the user from inserting the memory card of other specifications or re-inserting the memory card, the terminal is squeezed, and the creation can be used to prevent the memory card from being reversed. The stagnation part 14 is disposed in front of the conductive terminal group 2 • the front side of the splicing unit 2 2, and the surface of the stagnation unit 丨 4 has a slant surface, and the card 5 is pushed on the memory card 5, and the card 5 is first connected to the stagnation unit 1 4. The memory card 5 can be lifted up and forwarded simultaneously by the I material surface, and can be electrically connected to the conductive terminal group 2. If the memory card 5 is inadvertently inserted, the front end of the memory card 5 will be made. The end angle directly shouts the stagnation unit 1 4, and the stylus 5 cannot be moved forward, thereby preventing the memory card 5_ pushing and causing damage to the conductive terminal group 2. This structural design prevents the user from accidentally putting the memory card 5 reverse insertion, causing the conductive terminal group 2 to be damaged or 疋5 own} Sika 5 can not be pulled out. The main protection of this creation is that the terminal arrangement and the contact sequence can be used for the contacts on the memory card side by side. The conductive terminal group 2 in the card connector has a total of fourteen pins. The base 1! of the insulating base 1 is provided with nine pins A 2 to A 1 , and the contact portions 2 2 of the nine pins 2 to 1 1 are extended toward the base 13 and the base The worker 3 is provided with five pins A, a 11 to A14, ^W»A1, A1i~a14: ^_22 extending toward the base 1 1 to form a relatively row-shaped listening structure, and the base 1 is 3 The pin on which the brace grounding circuit is "the length is shorter than the other four pins A 1 1~A 14. When the memory card 5 is pushed in, the memory of the memory card 5 on the 13 M336594 vssp 1 n Contact with the lion A l with grounding loop to form a ground loop, and then carefully slap the foot, and finally the cymbal pedestal pin A 6 contacts the P in 6 contact on the memory card 5 to ensure that the memory card 5 pushes the person In place, the advantage of this design is that the side-by-side design of the conductive terminal sets and the length-to-length arrangement between the terminals can control the memory card contact terminals. The order is to simplify the number of terminals used (only • the legs), which in turn reduces assembly costs and man-hours, and solves the problem of prioritizing the formation of ground loops. • Only the above detailed description is for this creation. The description of the embodiments is not intended to limit the scope of the patent application, and all other variations and modifications of the scales that are not included in the spirit of the present invention should be included in the present disclosure. In the scope of patents, in summary, the card connector of this creation has significant power enhancement in use, and it is in line with the new, creative and progressive patent requirements, and the application of the silk law, hope that the trial committee will grant the case as soon as possible.
