New description: [New technical field] This is a signal connector, especially a signal connector made of a metal body and an insulating body group I. The signal connector can improve the traditional signal. In the assembly, the connector needs to insert a plurality of connection terminals into the insulating body one by one to enhance the production yield of the signal connector. [Prior Art] By button, the connector refers to all connected components and their accessories on the electronic signal and power supply. It is a bridge for all signals, and its quality will affect the reliability of current and signal transmission. It is also closely related to the operation of electronic systems. In the past, when manufacturing a signal connector, the manufacturer usually separately designed the components of the signal connector. This can increase the flexibility of the module. However, during the assembly of the signal connector, the assembler needs Inserting a plurality of connection terminals one by one into the signal connector, since the configuration of each part is minute and precise, the insertion action will greatly affect the efficiency of the production process, and the signal connector is also easy because of the failure of the insertion operation. As a result, the connection terminals are bent, which in turn affects the overall yield. For the manufacturer of the signal connector, there are undoubtedly many disadvantages in the assembly of the signal connector. Referring to Figure 1, there is a three-dimensional diagram of a conventional signal connector. The four-signal connection n 1 is composed of an insulating body and a metal casing n. The insulating body further includes a plurality of first-connections.

The metal sheet 115 can be folded toward the rear opening. In order to shield the rear opening 'only', the manufacturer usually assembles the insulating base body and the metal casing 11 and then folds the gold M mf. Therefore, after the first 示, the metal piece 115 is in a state of riding. The first connecting terminal 103 and the second connecting terminal 105 are also in a state of being bent, and the first and second connecting terminals 105 are also bent. As shown in FIG. 1 , one end surface of the tongue plate 101 is recessed. a plurality of grooves lGla and a slit (not shown), and the configurations of the grooves 1Q1a and the scales respectively The two connecting terminals 丨〇5 and one end of the first connecting terminal 丨 (10) are matched with each other, and a position of the adjacent end of the two opposite sides of the tongue plate 1 〇1 is respectively provided with a protruding portion l lb; the first insulating body 107 is opened a plurality of first jacks and second jacks 107b, wherein the first jacks 107a and the second jacks i7b extend through both end faces of the first insulator 107, and the configurations thereof are respectively The connecting terminal 103 and the second connecting terminal 1〇5 are matched, and a position of the end surface of the first insulator 1〇7 adjacent to the two corresponding sides is respectively recessed with a plugging groove 1〇7c, and the configuration is on the tongue plate 101. The protrusions l〇1b are matched; the second insulator 1〇9 is provided with a plurality of fixing grooves 109a, and the front opening 丨丨丨 and the rear opening of the metal housing 11 communicate with each other to form an accommodation. a space 113, and a position of the two corresponding sides adjacent to the rear opening is provided with a fitting portion 117, and the rear metal piece 115 is provided with a fitting hole intestine, the configuration of which matches the fitting portion 117, The assembly process of the signal connector is as follows: M405078 (1) Insert the first-connection terminal 1〇3 into the tongue plate 1 1 is inserted into the slot and has one end exposed on the tongue plate 101 adjacent to the other end. (2) Inserting the protrusions 1 lb 1 on the corresponding sides of the tongue plate 101 into the first insulator 107 In the slot i〇7c, the other ends of the first connecting terminals are simultaneously inserted into the first jacks 11a. (3) One of the second connecting terminals 1〇5 is terminated by the first insulator The other end face of the 1 through 7 passes through the second insertion hole l〇7b and is received in the recess 101a of the tongue plate 1〇1. (4) bending the first connection terminals 103 and The other end of the second connection terminal 1〇5 is parallel to the other end surface of the first insulator 107 and passes through the fixing slots i〇9a of the second insulator 109.

(6) After the metal casing η, the metal piece 115 is bent in the direction of the rear opening, and the fitting hole 115a and the fitting portion 117 are engaged with each other to prevent the insulating seat from slipping off from the rear opening. As can be seen from the above, when the signal connector 1 is assembled, the first connection terminal 103 and the second connection terminal 1〇5 are required to pass through the first insertion holes 1〇7a and the second insertion holes 107b one by one. The steps are not only complicated but also require a high degree of patience of the assembler. Otherwise, it is easy to fail and affect the production yield of the signal connector 1.
