[0002] A rectangular electrical connector is a component used to connect different parts of an electronic device or system, usually for transmitting power, data or signals. Rectangular electrical connectors can have different numbers and types of pins and are widely used in industrial equipment, automotive, aerospace and consumer electronics, etc.

[0003] The bent rectangular electrical connector is used for horizontal soldering on the circuit board, and its pins are bent 90 degrees, and the free ends of the pins are inserted into the soldering holes of the circuit board for soldering and fixing. However, the bent rectangular electrical connector has many pins, and the pins are easily skewed by external forces, and the skewed pins cannot correspond to the soldering holes on the circuit board, so the pins cannot be directly inserted into the soldering holes. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an auxiliary mounting bracket of a bent and inserted rectangular electrical connector in view of the deficiencies of the prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] The upper part of the bracket body is provided with horizontal steps, and each of the steps is provided corresponding to each row of the vertical sections;

[0008] The vertical sections are provided with vertically penetrating limiting holes at the projection positions corresponding to the steps, and the limiting holes are used to insert the vertical sections;

[0009] The horizontal sections are each provided with a horizontal limiting groove at a projection position corresponding to the step, and the limiting groove is used to snap into the horizontal section;

[0010] The top opening of the limiting hole is a bell mouth, and the limiting groove is communicated with the corresponding bell mouth.

[0011] Furthermore, the hole diameter of the limiting hole and the slot width of the limiting slot are slightly larger than the outer diameter of the pin.

[0012] Furthermore, the diameter of the limiting hole is not larger than the diameter of the welding hole.

[0013] Furthermore, the bracket body is in the shape of an elongated strip, and the limiting holes and the limiting grooves are evenly spaced and fully distributed on the corresponding steps.

[0014] Furthermore, the bottom of the limiting groove is a semicircular groove.

[0015] Furthermore, the bottom surface of the bracket body is horizontal, and the hole positions of the limiting holes on the bottom surface of the bracket body correspond one-to-one to the positions of the welding holes.

[0016] Furthermore, after the bent rectangular electrical connector is installed on the circuit board, the height of the horizontal section from the circuit board is consistent with the height of the bottom of the corresponding limiting groove from the bottom surface of the bracket body.

[0017] Furthermore, after the bent rectangular electrical connector is installed on the circuit board, the height of the top surface of the step is slightly higher than the height of the corresponding horizontal section.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] The limit holes of the utility model can realize the position calibration of the vertical section of the pin, and the arrangement of the limit holes on the horizontal bottom surface of the bracket body is consistent with the arrangement of the welding holes on the circuit board for installing the rectangular electrical connector. Therefore, the utility model can make the vertical section of the pin conveniently inserted into the welding hole of the circuit board to achieve quick installation.

[0020] The height of the bottom of the limit groove of the utility model from the bottom surface of the bracket body is consistent with the height of the horizontal section of the corresponding pin from the circuit board after the rectangular electrical connector is installed on the circuit board. Therefore, after the utility model is installed on the circuit board together with the rectangular electrical connector, the bottom surface of the bracket body fits the circuit board, the bracket body can support and limit the pins, the limit hole is used to limit the vertical section of the pin, and the limit groove is used to limit the horizontal section of the pin, which can avoid the risk of short circuit of the pins of the rectangular electrical connector when in use.

[0021] The bracket body of the utility model can also be set to a long strip shape, and the limiting holes and limiting grooves are evenly spaced and distributed on the corresponding steps. In this case, one specification of this embodiment can be suitable for the auxiliary installation of rectangular electrical connectors of various specifications, and rectangular electrical connectors with the same number of rows of pins and consistent pin spacing can all use the same specification bracket body. When it is necessary to cooperate with the rectangular electrical connector for installation, a suitable length can be cut from the bracket body.

[0022] The utility model has two usage modes: first, the pins of the rectangular electrical connector are first installed on the bracket body, at which time the vertical section of the pin is calibrated and can be conveniently inserted into the welding hole of the circuit board; second, the bracket body is first attached to the circuit board, the limiting hole is aligned with the welding hole, and then the vertical section of the pin is inserted into the limiting hole from the bell mouth, and the vertical section will also be directly inserted into the welding hole of the circuit board.

[0031] In order to better understand the present invention, the content of the present invention is further clearly described below in conjunction with the embodiments and drawings, but the protection content of the present invention is not limited to the following embodiments. In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0032] like Figure 1The schematic diagram of the bent and plugged rectangular electrical connector is shown in FIG. 1 . The rectangular electrical connector 1 includes a connector body 12 and pins 11. The pins 11 are all bent by 90°. The bent horizontal sections 111 are all vertically connected to the connector body 12. The bent vertical sections 112 are all used to be inserted into the welding holes of the circuit board. The pins 11 are mostly arranged in 1-5 rows, and the pins 11 in each row are evenly spaced. Assuming that the number of rows of pins 11 is n, the horizontal sections 111 are correspondingly distributed on n horizontal planes, and the vertical sections 112 are correspondingly distributed on n vertical planes.

[0033] Example 1: See Figure 1-Figure 4 The purpose of this embodiment is to provide an auxiliary mounting bracket for a bent-insertion rectangular electrical connector. The bracket body 2 includes a block-shaped bracket body 2, on which n steps 21 (n is the number of rows of pins 11) are arranged, each step 21 is arranged corresponding to the vertical section 112 of each row of pins 11, the top surface of the step 21 is horizontal, and is perpendicular to the vertical section 112 of the pin 11, and the height of the top surface of the step 21 is slightly higher than the height of the corresponding horizontal section 111.

[0034] Each step 21 is provided with a plurality of through-limiting holes 23 in the vertical direction. The limiting holes 23 are used to insert the vertical sections 112 of the pins 11. Therefore, the projection position of the vertical sections 112 of the pins 11 on the step 21 corresponds to the position of the limiting holes 23. The aperture of the limiting holes 23 is slightly larger than the outer diameter of the pins 11, and the aperture of the limiting holes 23 is not larger than the aperture of the welding hole on the circuit board for installing the pins 11. The axes of all the limiting holes 23 on the same step 21 are coplanar, and the plane is parallel to the side of the connector body 12 facing the pins 11. The center distance between two adjacent limiting holes 23 on the same step 21 is consistent with the center distance between adjacent pins 11 in the same row, so that the vertical sections 112 of all the pins 11 can pass through the corresponding limiting holes 23. At the same time, the top opening of the limiting holes 23 is a bell mouth 22, which is more convenient for the vertical sections 112 of the pins 11 to be inserted into the limiting holes 23 from top to bottom.

[0035] A limiting groove 24 is arranged horizontally on each step 21, and the limiting groove 24 is arranged one-to-one with the limiting hole 23. The projection position of the horizontal section 111 of the pin 11 on the step 21 corresponds to the position of the limiting groove 24. The width of the limiting groove 24 is slightly larger than the outer diameter of the pin 11, and the bottom of the limiting groove 24 is a semicircular groove. The axis of the limiting groove 24 is perpendicular to the side of the connector body 12 facing the pin 11, and one end of the limiting groove 24 is connected to the bell mouth 22, and the other end extends toward the connector body 12 and passes through the corresponding step 21. When the vertical section 112 of the pin 11 is inserted into the limiting hole 23, the horizontal section 111 of the pin 11 is correspondingly inserted into the limiting groove 24.

[0036] The bottom surface of the bracket body 2 is a horizontal plane, and the arrangement of the upper limit holes 23 on the bottom surface of the bracket body 2 is consistent with the arrangement of the welding holes on the circuit board for installing the rectangular electrical connector. Therefore, when the vertical sections 112 of the pins 11 pass through the limit holes 23, the limit holes 23 can realize the position calibration of the vertical sections 112 of the pins 11, so that the vertical sections 112 of the pins 11 can be easily inserted into the welding holes of the circuit board.

[0037] Therefore, the utility model has two usage modes: 1. First, the pin 11 of the rectangular electrical connector 1 is installed on the bracket body 2. At this time, the vertical section 112 of the pin 11 is calibrated and can be easily inserted into the welding hole of the circuit board; 2. First, the bracket body 2 is attached to the circuit board so that the limiting hole 23 is aligned with the welding hole, and then the vertical section 112 of the pin 11 is inserted into the limiting hole 23 from the bell mouth 22. The vertical section 112 will also be directly inserted into the welding hole of the circuit board.

[0038] The height of the bottom of the limiting groove 24 from the bottom surface of the bracket body 2 is consistent with the height of the horizontal section 111 of the corresponding pin 11 from the circuit board after the rectangular electrical connector 1 is installed on the circuit board. Therefore, after the utility model is installed on the circuit board together with the rectangular electrical connector 1, the bottom surface of the bracket body 2 fits the circuit board, the bracket body 2 can support the pin 11, the limiting hole 23 can limit the vertical section 112 of the pin 11, and the limiting groove 24 can limit the horizontal section 111 of the pin 11, which can avoid the risk of pin short circuit when the rectangular electrical connector is in use.

[0039] Example 2: See Figure 5 Compared with the embodiment 1, the auxiliary mounting bracket of the bent-insertion rectangular electrical connector provided in this embodiment mainly makes the following improvements: the bracket body 2 is long and has a length greater than 10 cm, and each step 21 of the bracket body 2 is covered with limiting holes 23 according to the center distance of the vertical segments 112 of the pins 11, and each limiting hole 23 is correspondingly provided with a bell mouth 22 and a limiting groove 24. When it is necessary to cooperate with the rectangular electrical connector 1 for installation, the bracket body 2 can be cut to a suitable length.

[0040] One specification of this embodiment can be suitable for auxiliary installation of rectangular electrical connectors of various specifications, and rectangular electrical connectors with the same number of rows of pins 11 and consistent spacing of the pins 11 can all use the same specification of the bracket body 2. This embodiment is also more suitable for mass production.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
