[Previous technology] For most connectors used for the purpose, the closed structure of the housing is designed to prevent stuns, usually the cross-section structure of the interface is designed to be left-right symmetrical, and the special structure with asymmetric upper and lower is usually in Under the condition of ensuring sufficient terminal docking space, the design of the lower side contour of the housing section of the connector is recessed to the inside of the housing. In order to enhance the physical robustness of the closed structure of the housing and make the contour shape more beautiful, The bottom of the housing is often designed with special geometric curves that meet good mechanical and aesthetic properties. The shape of the cross-section of the lower housing of a common connector is generally a two-corner in the lower part of the cross-sectional profile of the connector is recessed inward to form a recessed portion, which becomes an inverted "convex" -shaped structure. After the device is fixed to the circuit board, the bottom surface of the shielding sleeve of the case and the circuit board surface are often incompletely contacted, and the recessed contour part is easy to be inserted in the mating connector due to the lack of sufficient external strengthening support. In the process of connecting, it causes cracks and damage; in addition, it is poor; some electronic products sometimes need to adjust the height of the interface of the connector soldered to the circuit board relative to the circuit board. At this time, the bottom of the connector needs to be adjusted. Adding an insulating gasket to the circuit board, the extra process makes the assembly difficult, and increases the cost. In addition, in order to make the connector and the mating connector have sufficient clamping force, it is necessary to provide a sufficient number of clamping springs on the closed housing structure. In the conventional connectors, the The number is small and it is often difficult to provide sufficient holding power. [New content] The main purpose of this creation is to provide a more secure connector with a housing support #, the insulating body and shield housing of the connector have a combined support structure for f, and the support arm of the combined structure insulation body Cooperate with the support pins of the shield case to protect the snap part of the shield case from being damaged; and the thickness of the support arm of the insulating body can be adjusted to adjust the height between the connector and the circuit board.

At the position corresponding to the terminal portion on the rear end surface of the body, a terminal insertion portion is provided in the recess, and the insertion portion is provided with a plurality of insertion holes corresponding to the terminal grooves of the terminal portion. The insertion holes can be used for funneling and setting. Conductive terminal. In combination installation, a number of conductive terminals are embedded in the terminal insertion holes. The terminal's conductive portion is set at the terminal portion of the front body, and then the terminal portion of the insulated body combined with the terminal is closed by a shielded housing. The bottom end of the housing is inserted until the bottom edge touches the front face of the body. The inner side of the supporting arm of the insulating case closely fits the outer edge of the shielding case. The height of the supporting arm of the case is slightly lower than the front edge of the shielding case. , The inner side of at least one pair of pins of the shield case is firmly pressed against the outer side of the case support arm, and the at least one pair of case pins is inserted into a preset through hole on the circuit board. The enclosed shell provides sufficient support. At this time, the back card on the shielding case is inserted into the insulating body, that is, the engagement between the shielding case and the insulating body is realized, and then the bottom cover of the connector is bent down to a right angle to shield the connector. At the bottom, the connectors that make up the creation. The insulation body of the connector provided by this creation has special support to ensure that the shell's retaining structure is not damaged by the crack; the positioning pillars located at the bottom of the body are now connected! !! Money positioning with circuit board. [Embodiment] H First, the curved inner surface of the support is closely pressed against the curved surface of the outer side of the casing, relying on the elastic supporting force of the support arm itself, and the plug-in chat provided with the soldering of the circuit board socket firmly.

The insert piece 13 is inserted into the fixed slot 203 on the insulating body 2 and inserts into the body guide block 21 in the guide groove 17 for the same positioning and guide function. The pressing surface 130 on the bottom surface of the shield housing 1 closely contacts the front surface 26 of the body. The back check cards ι8 and 12 are respectively inserted into the back check slot 22 and the main body slot 25; then, the rear shield surface 105 (rear bending piece) of the housing is bent downwards, that is, the office constituting the specific embodiment of this creation Mentioned connector 4. As shown in FIGS. 7 and 8, the connector 4 of this embodiment cuts the κ holding piece Π on the upper shielding surface M2687Ji ,, ra, and the T shielding surface has 2 holding pieces 15 enough to hold the w to ensure the connection. The connector 4 has sufficient insertion and holding force between the connector 4 and the mating connector. The insulating body at the bottom of the connector is provided with two positioning posts for fixing the connector 4 to the circuit board 5, and the positioning posts 02 can be inserted into the positioning holes 55 on the circuit board 5 for reinforcing the connector. 4 and the circuit board 5. The circuit board 5 is provided with pin jacks 51, 52 corresponding to the pins of the connector 4 for accommodating the connector 4; ， 丨 ... ⑽ as shown in the figure, 'The pin is firmly soldered to the circuit board 5, the support bottom surface 200 and the support side 201 of the support arm are closely attached to the lower outer surface 14 of the housing, and the support arm of the housing is insulated at the same time. The lower side 204 of 20 is pressed against the surface of the circuit board 5. The inner side of the housing pin 16 of the connector 4 is pressed against the outer side of the support arm 20. The pin "is inserted into the pin socket 51 of the circuit board 5 and It is firmly welded, so the support arm 20, the surface of the circuit board 5 and a pair of pins 16 welded to the circuit board 5 together provide sufficient inward pre-supporting force for the lower recess 14 of the connector 4, namely, It is to provide a firm pre-supporting force for the closed shell of the connector 4 so as to provide sufficient internal pressure protection for the connector shell to ensure that the connector is in the process of mating with the mating connector. Even under the condition of large outward squeezing force, the concave wall surface of the shell can be supported by sufficient external force without being easily damaged; at the same time, the thickness of the shell support arm can be adjusted to adjust the connector welding as required. After the circuit board, the connector interface and circuit The height of the connector can be easily adjusted. As shown in Figure 13, the connectors 4 on the lower side of the connector are engaged with each other, and 12 are staggered and damaged. At the same time, it can be adjusted to affect the electronics. The stability of the product's use. Λ 冓 milk / Lianyi 4 The two bottom reinforcement tabs 13 on the two engaging shells on the bottom surface are inserted into the fixed plugs provided on the insulating body, respectively, so that the casing can be prevented from forming. The two metal pieces on the bottom surface are displaced up and down due to external force, and the engagement structure (dovetail groove in this embodiment) is caused by the upper and lower phases.
