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

[0016] 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.

[0017] like Figures 1 to 5 As shown, a patch-type 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 slots 22 are symmetrically provided on both sides of the front surface. Inserts 4 are inserted into the slots 22. The inserts 4 include L-shaped patches 41 that extend from the bottom surface of the housing 2.

[0018] Through the above scheme, several terminals 3 are inserted into 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 housing 2 is inserted with a plate 41, which fixes the housing 2 to the circuit board 1. This 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.

[0019] 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 circuit board 1 is provided with positioning holes 11 and fixing areas 12. The positioning pins 21 are inserted into the positioning holes 11, and the patch 41 is attached to the fixing area 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 patch 41 protrudes from the bottom of the outer shell 2. Then, the positioning pins 21 of the outer shell 2 are aligned with the positioning holes 11 and inserted. At the same time, the patch 41 is also attached to the fixing area 12. Then, the terminals 3 and the patch 41 are soldered to the circuit board 1 to complete the installation of the socket, which is convenient and firm.

[0020] like Figure 2 and Figure 4As 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.

[0021] 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.

[0022] like Figure 2 and Figure 4 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 connection.

[0023] 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.

[0024] like Figure 2 and Figure 5As shown, in one specific embodiment of the improvement, the insert 4 also includes a connecting post 42 that is connected to the upper side of the patch 41 and is vertically arranged, and a locking block 43 connected to the connecting post 42. The side of the locking block 43 is provided with a protrusion 44.

[0025] Specifically, patch 41 is located on the lower left side of connecting post 42, and locking block 43 is located on the upper right side of connecting post 42, so that there is a slot between patch 41, connecting post 42 and 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 upper surface of patch 41 is attached to the bottom surface of outer shell 2, and patch 41 is coplanar with the lower bottom surface of welding section 36 to avoid one end being raised and affecting welding. At the same time, there are two outward protrusions 44 on the left and right sides of locking block 43. Locking block 43 is adapted to slot 22, and the left and right inner sidewalls of slot 22 have grooves adapted to protrusions 44. When locking block 43 is inserted into slot 22, protrusions 44 are precisely embedded in the grooves, realizing the insertion of patch 4 and outer shell 2, preventing patch 4 from loosening and improving the firmness of structural connection.

[0026] like Figure 5 As shown, in one specific embodiment of the improvement, the top surface of the card block 43 is provided with a hook 45.

[0027] 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.

[0028] like Figure 3 As shown, in one specific embodiment of the improvement, the front end of the patch 41 is provided with a U-shaped notch 46.

[0029] Specifically, when the positioning post 21 is inserted into the positioning hole 11, it can help the patch 41 fit precisely into the fixing area 12. The area of ​​the fixing area 12 is larger than the area of ​​the patch 41. During soldering, the design of the notch 46 can prevent solder paste from overflowing, and at the same time increase the area of ​​solder paste climbing on the side, ensuring the quality of soldering and improving the stability of the connection.

[0030] 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.
