Therefore, they should not be construed as limitations on the embodiments of this application.

[0015] In order to better understand the above-mentioned objectives, technical solutions and advantages of this application, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings, and to understand in detail how to solve the problems raised in the background art.

[0016] like Figures 1 to 4 As shown, a straight-plug right-angle socket includes a housing 2 and a plurality of terminals 3 installed inside the housing 2. The rear end of the bottom surface of the housing 2 is provided with a positioning post 21 and the two sides of the front are symmetrically provided with slots 22. Inserts 4 are inserted into the slots 22. The inserts 4 include a fixing post 41 that is placed below the housing 2 and is vertically arranged.

[0017] Through the above scheme, several terminals 3 are installed on the housing 2. The positioning post 21 enables accurate insertion between the housing 2 and the circuit board 1 and assists in the precise soldering of the terminals 3 on the circuit board 1. Furthermore, the insert 4 with fixing post 41 is inserted into the housing 2. The fixing post 41 fixes the housing 2 to the circuit board 1, which can prevent the terminals 3 from becoming loose or falling off when there is vibration or external impact, thus improving the stability and firmness of the socket installation.

[0018] In this embodiment, the socket is installed on the circuit board 1, that is, the outer shell 2 is placed on top of the circuit board 1, and the terminals 3 are soldered and fixed to the circuit board 1. The outer shell 2 and the circuit board 1 are initially fixed. The circuit board 1 is provided with positioning holes 11 and fixing holes 12. The positioning pin 21 is inserted into the positioning hole 11 to limit and position, while the fixing pin 41 is inserted into the fixing hole 12 and soldered and fixed to the circuit board 1. The outer shell 2 and the circuit board 1 are further reinforced to avoid affecting the soldering of the terminals 3. The outer shell 2 is made of plastic and is injection molded, while the terminals 3 are made of metal and are formed by cutting, bending and other processes. In actual installation, firstly, several terminals 3 are inserted into the outer shell 2 and fixed. Then, the insert 4 is inserted from front to back into the slots 22 on both sides of the front of the outer shell 2, so that the fixing pin 41 protrudes downward from the bottom of the outer shell 2. Then, the positioning pin 21 of the outer shell 2 is aligned with the positioning hole 11 and inserted. At the same time, the fixing pin 41 is also inserted into the fixing hole 12. Then, the terminals 3 and the fixing pin 41 are soldered to the circuit board 1 to complete the installation of the socket, which is convenient and firm.

[0019] like Figure 1 and Figure 2As shown, in one specific embodiment of the improvement, the diameter of the positioning hole 11 is larger than the diameter of the fixing hole 12.

[0020] Specifically, the positioning hole 11, positioning post 21, fixing hole 12, and fixing post 41 are cylindrical and there are two of each. The diameter of the positioning hole 11 is larger than the diameter of the fixing hole 12, which makes the diameter of the positioning post 21 larger than the diameter of the fixing post 41. When the outer shell 2 is installed on the circuit board 1, it can prevent the outer shell 2 from being misinstalled or installed incorrectly, thus playing a foolproof role. Of course, in actual production, the diameters of the two positioning posts 21 can also be set to be one large and one small, so that there will be a significant difference, which can further prevent the outer shell 2 from being installed backwards.

[0021] like Figure 2 and Figure 3 As shown, in one specific embodiment of the improvement, the terminal 3 includes an upper spring piece 31 and a lower spring piece 32 arranged opposite to each other. Both the upper spring piece 31 and the lower spring piece 32 include an abutting section 33, an elastic section 34 fixedly connected to the abutting section 33, an insertion section 35 fixedly connected to the elastic section 34, and a welding section 36 fixedly connected to the insertion section 35. The welding section 36 is L-shaped and located outside the housing 2.

[0022] Specifically, the upper spring piece 31 and the lower spring piece 32 are symmetrically arranged vertically, and the elastic segment 34 is inclined towards the center of the insertion cavity 37, so that the contact area can be increased after the plug is inserted into the socket, thereby enhancing the connection effect. The elastic segment 34 and the outer shell 2 are either an integral structure or a separate structure. The integral structure is formed by in-mold injection molding of the outer shell 2 to improve the strength of the connection structure. In this embodiment, a separate structure is adopted. The separate structure achieves insertion by setting a slot in the outer shell 2 that is compatible with the elastic segment 34, that is, the width and height of the elastic segment 34 are greater than the width and height of the abutment segment 33 and the elastic segment 34. The structural design of the elastic segment 34 is used to fasten it to the outer shell 2, so as to achieve complete embedding of the terminal 3 and prevent the terminal 3 from loosening or falling off. The welding segment 36 is L-shaped and is bent relative to the tail end of the elastic segment 34 and placed outside the outer shell 2. This allows the upper part of the welding segment 36 to fit against the rear end face of the outer shell 2 and form front and rear limit for the installation of the terminal 3, which is conducive to the rapid installation of the terminal 3. Furthermore, the elastic segment 34 of the upper spring piece 31 is longer than the elastic segment 34 of the lower spring piece 32, so that the welding segments 36 of the upper spring piece 31 and the lower spring piece 32 are distributed front and back, forming a matching structure with one long and one short.

[0023] like Figure 3 As shown, in one specific embodiment of the improvement, the front ends of the two abutting sections 33 are bent upward and downward respectively, and the upper spring piece 31 and the lower spring piece 32 together form a plug-in cavity 37 for electrical connection.

[0024] Specifically, the front end of the outer shell 2 has a socket for inserting a plug and a cavity communicating with the socket, which enables the plug to be connected to the socket; the front end of the abutting section 33 of the upper spring 31 is bent upward, and the front end of the abutting section 33 of the lower spring 32 is bent downward. There is a gap between the upper and lower elastic sections 34, which together form a plug-in cavity 37. The abutting section 33 and the elastic section 34 are housed in the cavity. The cavity can provide space for the abutting section 33 and the elastic section 34 to extend or deform elastically, so that the plug is not obstructed when inserted into the plug-in cavity 37 and is difficult to insert. In addition, the two abutting sections 33 can also clamp the plug from top to bottom to ensure the stability of the connection.

[0025] like Figure 2 and Figure 4 As shown, in one specific embodiment of the improvement, the insert 4 further includes an L-shaped connecting block 42 connected to the fixing post 41 and a locking block 43 connected to the connecting block 42. The side of the locking block 43 is provided with protrusions 44.

[0026] Specifically, the fixing post 41 is located at the front end of the connecting block 42, and the tail end of the connecting block 42 is connected to the lower rear end of the locking block 43, so that there is a slot between the connecting block 42 and the locking block 43. The outer shell 2 is provided with a matching insert structure, so that the insert can be embedded into the slot. The fixing post 41 extends downward from the bottom surface of the outer shell 2. At the same time, there are two outward protrusions 44 on the left and right sides of the locking block 43. The locking block 43 is compatible with the slot 22, and the left and right inner sidewalls of the slot 22 have grooves that are compatible with the protrusions 44. When the locking block 43 is inserted into the slot 22, the protrusions 44 are precisely embedded in the grooves, realizing the insertion of the insert 4 and the outer shell 2, preventing the insert 4 from loosening and improving the firmness of the structural connection.

[0027] like Figure 4 As shown, in one specific embodiment of the improvement, the top surface of the card block 43 is provided with a hook 45.

[0028] Specifically, there are three hooks 45. The hooks 45 are positioned from front to back along the width of the outer shell 2. The upper inner side wall of the slot 22 is provided with a hook groove that matches the hooks 45, which is conducive to the accurate and quick insertion of the insert 4. At the same time, it can also limit the insertion 4 in front and back, further improving the firmness of the structural connection.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
