Further, the magazine terminals 23a, 23b, the contact portions 9Ga, m are in contact with the external electrode core, and (10) the 'fixing portions 92a, 92b are connected to the fixed substrate 4 (). This acts as a terminal for transmitting the signal between the relay circuit 10 and the signal circuit. The insulating portion 25 has a rectangular parallelepiped shape and is made of a resin. The insulating portion Μ and the spring terminals 23a and 23b are integrally formed. Thereby, the spring terminal & 23b is fixed to the socket body 21 by the insulating portion so as not to be electrically connected to the socket body 21. In more detail, the spring portion 9U and the spring portion 91 and the insulating portion 25 are formed. The side surface on the positive side in the y-axis direction and the side on the negative side in the y-axis direction are drawn out, and the fixing portions 92a and 92b are provided.

As shown in Fig. 2 and Fig. 2, the holding members 70 to 73 are fitted to the concave portions 8A to 83, respectively. Further, the spring end portions zJa, 23b are in contact with the external electrodes 16a, 16b, and the spring terminals 23a, 23b are external to each other. The electrode 14 201243409 16a, 16b is crimped. Further, the 'plug 〇 is pressed by the spring terminals 23a, 23b toward the positive side in the y-axis direction. By this, the plug 1 〇 is fixed to the socket 2 〇. As shown in Fig. 7, the receiving connector u and the transmitting connector lb are respectively provided at both ends of the optical fiber 50. In addition, the receiving device is used for the receiving and receiving system of the connector. The connector 1a includes a receiving circuit board 40a and a photodiode 12a. The transmitting connector lb includes a transmitting circuit board 40b and a VCSEL 12b, thereby receiving the signal from the transmitting connector lb via the optical fiber 5 The signal is transmitted by the connector la. (Effect) As explained below, according to the connection丨, a high SN ratio can be obtained. In more detail, the contact portions 90a, 90b* are crimped to the external electrodes l6a, i6b. Therefore, the contact areas of the contact portions 90a, 90b and the external electrodes are compared. In the case of such non-crimping, the contact area is large, so that the resistance between the contact portion 90b and the external electrodes 16a, 16b is also lower than the resistance value of the uncompressed case, thereby passing through the socket 2 from the plug 10. (The current value of the electric signal transmitted by the M main circuit unit 3 becomes large. Therefore, the SN ratio can be obtained according to the connector. According to the socket 20, the plug 1 is fixed to the socket 20 by the holding members 7A to 73, so that the fitting force of the plug 10 and the socket 2 can be made strong. Hereinafter, description will be made with reference to the drawings. Fig. 8(a) is a view for explaining the fitting force of the case where the plug 1A and the socket 2 are fitted at the four corners of the plug 1A. The figure is used to illustrate the fitting force of the plug and socket 220 in the case where the plug 21 is to be joined. As shown in Fig. 8(a), the plug 10 and the socket 2 are embedded in the four corners of the plug (7) 15 201243409. As shown in Fig. 8(b), the plug 21〇 and the socket 22 are at the two ends of the end of the plug in the negative direction of the X-axis direction and the positive direction of the X-axis direction of the plug 2丨〇. In the case where the two portions other than the end portion of the side are fitted, the ease of detachment of the plug ι, 2 〇 when the optical fibers 5 〇, 250 are pulled in the positive direction of the two-axis direction is compared. When the optical fiber 50 is pulled in the positive direction side in the two-axis direction, the fulcrum of the end portion on the negative side in the X-axis direction of the fulcrum-type plug 10, 210 is S° where F1 is the optical fiber 5〇, 25〇2 The force of pulling in the positive direction of the axial direction, F2 is the force applied to the plugs 1〇, 21〇 by fitting. u is the length from the point where the force is applied to the optical fibers 5 〇, 250 to the fulcrum s, and L2 is the point at which the end plug 1 〇 and the socket 2 〇 are fitted from the positive side in the X-axis direction of the socket 2 至 to the fulcrum The length eL3 is the moment from the point where the plug 210 and the socket 22 are fitted to the end portion on the negative side in the direction of the parent axis of the socket 22, and the fulcrum degree (4) is the moment of the force running clockwise around the fulcrum S. For example, the torque of the force running clockwise around the fulcrum S. As shown in Fig. 8 (4), when the optical fiber 5 is pulled toward the positive side in the two-axis direction by the force of F1, the moment of the force running clockwise around the fulcrum S is F1L1. At this time, the torque of the counterclockwise force is F2L2n Μ# by the plug ‘’ odt „ 兴 sp庄 (9) fitting with the fulcrum s as the center. The moment of the hour hand movement is as shown in the formula (1). '", M1=F1L1-F2L2·.. (1) m oyojrrj When the special fiber 250 is pulled in the z-axis direction jy, the F1U is operated clockwise from the center of the point s, which is the same as in the case of Fig. 8(4). It is made by the peasant 210^2 2 0, and the enthusiasm of the sturdy squirrel ▲ and 才. 乂 ' ', " the counterclockwise force of the force is the coffee 16 201243409 Therefore, the fulcrum s centered on the clockwise operation The torque of the force is expressed by the formula (2). β M2 = F1L1 - F2L3 (2) Here, from Fig. 8(a) and Fig. 8(b), since L2 > L3 is established, the comparison formula (1) After the formula (2), M1 < M2. Therefore, as shown in Fig. 8 (a), when the plug 1 〇 and the socket 20 are fitted at the four corners, the moment at which the plug is detached from the socket is small. That is, the plug 10 The plug 210 is less likely to be detached from the socket, and the plug 1 〇 has a strong fitting force with the socket 20. Further, according to the socket 20, even if the plug 丨〇 is fitted to the four corners of the socket 10 to increase the fitting force, it is also possible to seek The height of the connector * is lowered. In more detail, the holding members 7A to 73 are not located at the four corners of the opening of the socket 20 as shown in Figs. 5 and 6. Therefore, the magazine terminals a, 23b are disposed. When viewed in the z-axis direction, it is in the shape of a zigzag extending in the y-axis direction. The holding members 71 and 73 are in contact with the spring terminals 23a and the coffee. In order to avoid the situation, the magazine terminals 2杌23 may be considered. It is placed in the y-axis direction [I # is inverted U-shaped. However, in this case, the length of the socket 20 in the Z-axis direction becomes long, and the height of the socket 2 can not be lowered. Here, the spring terminals 23a, 23b have the following configuration =, and the magazine member has a sub-shape from the vicinity of the midpoint in the y-axis direction. In other words, when the spring member 93a is viewed in the direction of the positive direction, it is curved toward the positive side of the X-axis square center in the direction of the y-glazed direction, z-axis side. Similarly, the spring member is positively oriented. When viewed from the direction side, the negative side of the direction toward the X-axis and the glaze direction is toward the negative side of the direction. Thereby, the spring members 93a, 93b, which are opposed to the holding members 71, 17 201243409 73 located at the position closest to the spring terminal 23a, are bent toward the direction away from the holding member. As a result, the spring members 93a and 93b are restrained from coming into contact with the 73 of the protection member 3, and the height of the socket 2 can be reduced. Further, the spring member 23', the spring-like portion 23a, the "folded portion of the character" is located on the positive side of the y-axis direction or the side of the negative side of the y-axis direction of the side m or the side η. Therefore, the spring portion 91a can be made The length of 91b is sufficient ^, even if the spring terminals 23a, 23b are largely displaced, it is not easy to produce plastic: shape. That is, 'the spring terminals 23a, 23b can obtain high elasticity. As shown in Fig. 5' by the socket body 21 The notches A to D become the structures in which the end portions of the holding members 70 to 73 are 7 〇 a 7 y a 79 a 7*5 λ i are not in contact. 57h '73a _ the core body 21 is notched A to D, as shown in FIG. As shown in FIG. 6, the trapezoidal shape in which the width in the direction of η and the x-axis is narrowed as viewed from the side, and the socket 20 is rectangular in comparison with the notches A to D, the socket body 2 is The area becomes larger 'so the strength of the socket body 21 becomes $. The end portions 7〇3, 713, 723, 73 of the holding members 70 to 73 are wider than the end portions, and are called (10)... axial direction axis: this 'even if the areas of the notches A to D become smaller', the holding members 70 to 73 can be embedded. To gaps A to D. The inlet members 70 to 73 have a hook shape which is connected to the end portion of the socket body 21, and 73b as a starting point. Therefore, the holding members 7A to 73, the length of the portion acting as a spring is long, so that plastic deformation is caused even if it is largely eliminated. That is, high elasticity can be obtained. Further, as shown in Fig. 5, in the holding members 70 to 73, the end portions 7〇a to Da are largely displaced from the socket main body 2 when 18 201243409 70 to 73 are largely displaced. Therefore, the more the plastic deformation of the holding member is, the more the displacement is not greatly changed. The positive direction side is press-fitted into the y-axis direction by the contact portions 90a, 90b to be fixed to the socket body 21. The insertion portion 90a, _ < the front end can be mechanically inclined to be inclined to the elastic member 93a, respectively, at an angle of about 45. . Therefore, the contact portions 9〇a, 9〇b are introduced into the head 10. The contact portions 90a, 90b are displaced in the axial direction by the spring member 93a. Here, as shown in Fig. 5, an insulating portion 25 is provided on the side of the contact portion 9A, which is in the negative direction of the axis direction of the crucible. Therefore, if the contact portion 9A, _ is largely displaced, it abuts against the insulating portion 25β, so that the plastic deformation is less likely to be displaced. In the socket 20, as shown in Figs. i and 2, the fixing member - the skin press-fitting hole 41. Therefore, when the plug 1 is inserted and removed from the socket 2, the plug is lifted in the positive direction of the z-axis direction, whereby the socket 20 is surely applied even if the stress is applied to the socket 20 on the positive side in the z-axis direction. Since it is mounted on the circuit board 4, it does not fall off from the circuit board 40. As shown in FIG. 2, when viewed from the positive side (upper side) in the z-axis direction, the socket body 21 is in the shape of a plug 1 ,, so that the plug 1 〇 is not easily detached from the socket 2 ' 'Enhanced plug 1 〇 and socket 2 The chimerism of 〇. Fig. 9 is a view showing a front end portion of the pin group type item E used when the plug 〇 is inserted and removed from the socket 2 。. In the connector, since the prop e-plug 10 is inserted and removed from the socket 20, the hand does not need to touch the optical fiber 50 or the like during the insertion and removal. Since the stress on the optical fiber 5 能 can be alleviated, no burden is placed on the optical fiber 5 〇 201243409, and the smash is prevented from being broken. More specifically, by embedding the L-shaped props J (4., M, N) of the circle 9 into the recess U, V of the plug 1 (refer to Fig. 2 and the circle 3), the actor α The plug 10 is inserted and removed from the socket 20. When the plug 10 is inserted into the socket 20, the plug 10 is clamped with the finger 1 c + and the E is inserted from the positive side of the z-axis direction of the socket body 21. As shown by the circle 2, it is confirmed that the plug 1 () and the socket 20 are fitted through the notches M, N, so that the efficiency of the fitting work is improved. Further, the metal cover 33 and the metal member 8 are connected to the socket body 2! Therefore, the ground potential is the same potential. Thereby, the connector 遮 entirely blocks the noise from the outside, and the connection H 1 can exert a shielding effect. By the shielding effect, the ESD resistance (electrostatic discharge) of the circuit component 31 can be achieved. Improved resistance to em). Further, the EMC of the external electrical interface can be increased. The metal member 18 and the socket body 21 are made of metal, and are respectively connected to a ground conductor (not shown) of the circuit board 40. Therefore, a large current caused by static electricity is guided to the ground through the metal member 18, the socket body 2, and the ground conductor of the circuit board 4. As shown in Figs. 1 and 2, the plug 10 is in contact with the socket 20 through metal holding members 70 to 73. Therefore, it is less likely to cause wear between the plug 1A and the holding members 7A to 73, and the contact deviation due to the variation of the shape of the plug 1 and the holding members 7A to 73 can be prevented. Since the plug 10 and the socket 2Q are fixed by fitting the metal member 18 to the socket body 21, they are fitted. The guest gel has a strong feeling and can be actually felt by sound and feeling. (Other embodiments) 20 201243409 The connector assembly configured as described above is not limited to the above embodiment. Therefore, the connector 1 can be changed within the scope of its gist. In the present embodiment, the photoelectric conversion element of the socket body 21 is the light receiving element 12' but may be a light emitting element. The light-emitting element converts the electrical signal output from the circuit unit 3 into an optical signal and outputs it to the optical fiber 5 。. At this time, the IC 32 of the circuit unit 30 functions as a drive circuit. 1 (: 32 is electrically connected to the pin terminal..., 23b, and generates an electrical signal to the light emitting element. Here, the IC 32 outputs a current value corresponding to the amount of light of the light emitting element. Therefore, when the amount of light of the light emitting element is small, IC32 The electric rolling nickname having a weak current value is output. Therefore, there is a problem that the SN ratio becomes low after the noise is mixed into the electric signal. In this case, the plug 10 and the socket 2 are crimped to be effective. Further, the external electrodes 16a, 16b For the spring terminal, the spring terminals 23a, 23b provided in the socket 2 are replaced by plate-shaped external electrodes. In this case, the 卩 electrodes 16a, 16b are from the y-axis direction (horizontal direction and the optical fiber is the father In the direction of observation, a U-shaped leaf spring is in contact with the socket 2A. Fig. 10 is a schematic configuration diagram of a transceiver system 100a using a connector of another embodiment, as shown in Fig. 1 The SERDES device 99 may be provided by the connector ia and the communication connector lb. The SERDES device 99 is configured on the circuit substrate 4 〇e SERDES device 99 converts the serial signal into a parallel signal, and converts the parallel signal into a serial Signal. Since the distance between the driving circuit and the SERDES device is narrowed, the optical transmission characteristics are improved. In the connector 1, the metal cover 33 and the socket body 21 are integrated, thereby making the connector 1 resistant to ESD and EMC as a whole. In addition, the number of parts is reduced to reduce the cost, and the number of steps is reduced. 21 201243409 The production time can be shortened. Although the socket 20 is provided with four holding members, it is also possible to protect more than one. In the case of the plural: five inlays... (a), one or two: the contact method is provided with a plurality of notches in the socket body 21. In the socket 20, although two spring terminals are provided, the spring terminals are only one =. Even if - The spring terminal ' can be connected to the external electrodes 16a, 16b or the circuit board (illustration) as long as it has a fixing portion at both ends thereof. The optical fiber 50 and the light receiving element 12 of the flat type (not mounted on the plug H) may be plural. This can increase the transmission capacity. Further, the optical fiber 5 〇 and the light receiving element 12 may be arrayed. It is also possible to select such an optical fiber for the organic optical waveguide path or for the purpose of use. The optical fiber 50 may be a quartz optical fiber P〇F (Plastic Optical Fiber). Transfer path. Further, the metal member 18 and the metal cover 33 may not be made of metal. This month is useful in connectors, especially where it provides a connector that achieves a high SN ratio.
