[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0034] Please refer to Figure 1-Figure 4 , is a heat dissipation and anti-loosening connector 100 described in an embodiment, which includes a connecting base 10, the connecting base 10 is provided with a first plug hole 11; a terminal 20, the terminal 20 has a first connecting end and a second connecting end opposite to each other, the first connecting end is inserted into the first plug hole 11 and fixed; and a fixing member 30, the fixing member 30 is assembled with the connecting base 10, and the fixing member 30 is provided with a second plug hole 31, and the second connecting end is inserted into the second plug hole 31 and fixed.

[0035] The implementation of the embodiment of the utility model will have the following beneficial effects: in the heat dissipation and anti-loosening connector 100 of the present solution, the terminal 20 can be assembled and matched with the connecting base 10 and the fixing member 30 respectively to achieve installation and fixation. Specifically, the terminal 20 has a first connecting end and a second connecting end relative to each other, the connecting base 10 is provided with a first plug hole 11 and the fixing member 30 is also provided with a second plug hole 31. During installation, the first connecting end and the second connecting end are respectively inserted into the first plug hole 11 and the second plug hole 31 in the corresponding position, so that both ends of the terminal 20 can be limited by the hole wall and installed and positioned. Compared with the single-end fixed installation method of the prior art, the terminal 20 of the present solution has better installation stability and is not easy to shift and loosen under the influence of factors such as vibration, thereby ensuring that the heat dissipation and anti-loosening connector 100 is in good contact in the installed state and ensuring the signal transmission performance of the heat dissipation and anti-loosening connector 100.

[0036] In the present application, according to the different structural shapes of the terminal 20, the heat dissipation and anti-loosening connector 100 can be specifically divided into two types: vertical and horizontal.

[0037] Specifically, in the vertical heat dissipation and anti-loosening connector 100, in one embodiment, the terminal 20 is set to an L-shaped bending structure, the first connection end is an end of the long section of the terminal 20 away from the short section, and the second connection end is an end of the short section of the terminal 20 away from the long section. When the heat dissipation and anti-loosening connector 100 is in the installed state, the long section of the terminal 20 is arranged horizontally and the short section is arranged vertically. This structural arrangement form can be applied to the occasion where the circuit board is installed below the heat dissipation and anti-loosening connector 100.

[0038] In order to further improve the installation stability of the first connection end in the first plug hole 11, a clamping protrusion 21 is protruded from the outer wall of the first connection end, and the clamping protrusion 21 is clamped with the hole wall of the first plug hole 11. For example, the cross section of the terminal 20 is rectangular, and the upper and lower parts of the two side surfaces in the width direction of the terminal 20 are both protruded with clamping protrusions 21, that is, the outer periphery of the terminal 20 has a total of four clamping protrusions 21 for clamping with the hole wall of the first plug hole 11, thereby greatly improving the assembly firmness of the terminal 20 and the connection base 10, and preventing the first connection end from moving and loosening in the first plug hole 11.

[0039] In one embodiment, both ends of the fixing member 30 in the length direction are provided with first hooks 32, and both inner walls in the width direction of the connecting seat 10 are provided with first slots 12, and the first hooks 32 are snap-connected with the first slots 12. By snapping the two sets of first hooks 32 on both sides with the first slots 12, the fixing member 30 and the connecting seat 10 can be assembled and fixed, and the terminal 20 is installed and positioned to ensure that the overall structure of the heat dissipation and anti-loosening connector 100 is stable.

[0040] It should be noted that the first slot 12 is set as a two-level slot structure, that is, the first hook 32 will first pass over the first-level slot when it is pushed downward at least into the connecting seat 10. The fixing member 30 and the connecting seat 10 can be pre-installed and fixed by engaging with the first-level slot. At this time, the freedom of the column terminal 20 will not be completely constrained, which facilitates the adjustment of the position of the terminal 20. Then, the first hook 32 is pushed and finally engaged with the second-level slot, so that the fixing member 30 and the connecting seat 10 can be finally assembled and fixed.

[0041] Further, in another embodiment, both ends of the fixing member 30 in the length direction are provided with positioning stopper columns 33 and positioning blocks 34, and both sides of the connecting seat 10 in the width direction are provided with positioning slots 13, and the positioning stopper columns 33 are correspondingly abutted against the inner walls on both sides of the connecting seat 10 in the width direction, and the positioning blocks 34 are engaged in the corresponding positioning slots 13. When the fixing member 30 and the connecting seat 10 are assembled, the fixing member 30 is pushed toward the connecting seat 10 from bottom to top, and the first hook 32 is engaged with the first slot 12, and the positioning block 34 is simultaneously engaged in the corresponding positioning slot 13, so as to realize the installation limit in the vertical direction; at the same time, the two positioning stopper columns 33 are respectively inserted into the connecting seat 10 and abut against the two inner side walls in the width direction of the connecting seat 10, so as to form horizontal positioning, prevent the fixing member 30 and the connecting seat 10 from being lateral displacement and loosening, and further improve the stability of the assembly structure.

[0042] In addition, in one embodiment, the bottom surface of the fixing member 30 is further provided with a support foot. The support foot is specifically a cylinder, which is provided with two and spaced apart. When the heat dissipation and anti-loosening connector 100 is assembled with the circuit board, the end of the support foot supports the board surface of the circuit board to improve the installation stability of the heat dissipation and anti-loosening connector 100.

[0043] The outer wall of the connection base 10 is also provided with a second hook 14 extending in the same axial direction as the support foot. The second hook 14 is used to engage with the hole on the circuit board, so that the heat dissipation and anti-loosening connector 100 has a higher connection strength and better stability with the circuit board.

[0044] See also Figures 5 to 7In another embodiment, the heat dissipation and anti-loosening connector 100 adopts a horizontal structure, in which case the terminal 20 is set to a straight structure, and the fixing member 30 includes a first fixing plate 30a and a second fixing plate 30b arranged in a stacked manner, and the first fixing plate 30a and the second fixing plate 30b are both provided with a second jack 31 in alignment. That is, the first fixing plate 30a is provided with a second jack 31, and the second fixing plate 30b is also provided with a second jack 31, and the second jack 31 on the first fixing plate 30a is aligned with the second jack 31 on the second fixing plate 30b.

[0045] The second fixing plate 30b is disposed between the first fixing plate 30a and the connecting seat 10, the connecting seat 10 has a connecting column 15, the first fixing plate 30a is provided with a connecting through hole 31a, and the connecting column 15 is inserted into the connecting through hole 31a. When the stacked first fixing plate 30a and the second fixing plate 30b move toward the connecting seat 10, the connecting column 15 can be automatically inserted into the connecting through hole 31a, so that the first fixing plate 30a, the second fixing plate 30b and the connecting seat 10 are assembled and fixed as a whole, the installation method is simple, and the connection reliability is high.

[0046] Further, the second fixing plate 30b is provided with a third hook 31b on both sides of the length direction, the second fixing plate 30b is provided with a fourth hook 32b on at least one side of the width direction, the second slot 16 is provided on both sides of the width direction of the connecting seat 10, the third slot 17 is provided on at least one side of the thickness direction of the connecting seat 10, the third hook 31b is engaged in the second slot 16, and the fourth hook 32b is engaged in the third slot 17. On the basis of the above embodiment, by engaging the third hook 31b with the second slot 16 and the fourth hook 32b with the third slot 17, the second fixing plate 30b can be further assembled and fixed with the connecting seat 10, thereby improving the overall connection stability of the fixing member 30 and the connecting seat 10, and ensuring that the first fixing plate 30a and the second fixing plate 30b can provide stable support and positioning for the terminal 20 of the straight structure.

[0047] In another embodiment, the second fixing plate 30b is further provided with a limiting groove 33b, and the inner wall of the connecting seat 10 is further provided with a limiting protrusion 18, and the limiting groove 33b is fixedly engaged with the limiting protrusion 18. With the limiting protrusion 18 being engaged with the limiting groove 33b, the connection strength between the second fixing plate 30b and the waist part of the connecting seat 10 can be further improved, thereby helping to improve the overall assembly strength and structural stability of the fixing member 30 and the connecting seat 10.

[0048] In actual work, since the terminal 20 is made of metal, a large amount of heat will be generated when it is powered on for a long time. If the heat accumulates in a closed space for a long time, it is easy to affect the service life of the terminal 20 due to overheating. Based on this, in one embodiment, a heat dissipation groove 40 is formed at one end of the connection seat 10 facing the fixing member 30, and the part of the terminal 20 located between the first connection end and the second connection end is suspended in the heat dissipation groove 40. Therefore, the heat generated by the terminal 20 can be dissipated from the notch of the heat dissipation groove 40 to the external environment in a timely manner, which helps the terminal 20 to dissipate heat and cool down in a timely and effective manner.

[0049] In one embodiment, both outer walls on both sides of the width direction of the connection base 10 are provided with inclined convex parts 19. For example, the inclined convex parts 19 are formed into a triangular plate structure, which can enhance the structural strength of the connection base 10 on the one hand, and can also be used as a pressing part on the other hand, so as to facilitate the downward pressure of the hand when the heat dissipation and anti-loosening connector 100 is assembled with the circuit board, and facilitate the heat dissipation and anti-loosening connector 100 and the circuit board to be assembled as one.

[0050] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
