DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figures 1 to 4 A terminal fixing structure is shown, which includes a fixing base 10, a terminal body 11 and a fixing cover 12, wherein the fixing base 10 can be fixedly installed on a connector housing 20, and a mounting groove 101 and a buckle groove 102 are also provided on the fixing base 10, the terminal body 11 can be a male or female terminal, and the terminal body 11 can be fixed in the mounting groove 101 by the fixing cover 12, specifically, limiting arms 121 extend from opposite sides of the fixing cover 12, and a first buckle 122 matching the buckle groove 102 is provided at the far end of the limiting arm 121, and the two limiting arms 121 can be clamped on opposite sides of the terminal body 11, and the fixing cover 12 and the bottom of the mounting groove 101 further limit the other opposite sides of the terminal body 11, so as to fix the terminal The sub-body 11 is fixed in the mounting groove 101, that is, the fixed cover 12, the two limiting arms 121 and the bottom of the mounting groove 101 together form a clamp structure and respectively position the four sides of the terminal body 11, so as to fix the terminal body 11 in the mounting groove 101, and a plug-in portion 111 is provided at one end of the terminal body 11, and the plug-in portion 111 is correspondingly connected to the corresponding male or female terminal, and the other end can be connected to the wire 112; in this embodiment, since the relative position of the terminal body 11 and the connector housing 20 is fixed, it is very convenient to align the male and female terminals and connect the wire 112 to the terminal body 11, that is, the structure of the present application is conducive to automated production, thereby improving production efficiency.

[0023] In some embodiments, a mounting through hole 21 for accommodating the fixing seat 10 is provided on the connector housing 20, and a panel 107 is also provided on the fixing seat 10, and the outer dimensions of the panel 107 are larger than the aperture of the mounting through hole 21, so that the fixing seat 10 can partially pass through the mounting through hole 21 while the panel 107 cannot pass through the mounting through hole 21, and the outer side surface of the fixing seat 10 is also provided with a second buckle 103 that cooperates with the edge of the mounting through hole 21, and the second buckle 103 can pass through the mounting through hole 21 with the fixing seat 10, and the second buckle 103 will undergo a certain elastic deformation when passing through the mounting through hole 21, and the second buckle 103 will recover and block the fixing seat 10 from exiting the mounting through hole 21 after passing through, while the panel 107 can block the fixing seat 10 from passing through the mounting through hole 21 as a whole, so the second buckle 103 and the panel 107 cooperate to fix the fixing seat 10 on the connector housing 20.

[0024] In some embodiments, a plurality of limiting ribs 104 are also formed on the outer side surface of the fixing seat 10. The limiting ribs 104 can be distributed around the fixing seat 10, and the limiting ribs 104 gradually protrude and extend from the open end of the mounting groove 101 on the fixing seat 10 to the closed end. During installation, the limiting ribs 104 pass through the mounting through hole 21 with the fixing seat 10 and the limiting ribs 104 gradually press against the inner wall of the mounting through hole 21, thereby fixing the fixing seat 10 to the mounting through hole 21. Such a structural design can not only accurately locate the position of the fixing seat 10 in the connector housing 20 / mounting through hole 21, but also limit the fixing seat 10 from continuing to move along its axial direction through the friction between the limiting ribs 104 and the inner wall of the mounting through hole 21, so as to avoid the problem that the spacing between the second buckle 103 and the panel 107 is greater than the thickness of the connector housing 20, causing the fixing seat 10 to slide relative to the connector housing 20 along its axial direction.

[0025] In some embodiments, an anti-foolproof protrusion 22 is also provided on the inner side of the mounting hole 21, and an anti-foolproof notch 105 is formed on the upper side of the fixing seat 10 to give way to the anti-foolproof protrusion 22, the purpose of which is to ensure that the fixing seat 10 is placed on the mounting hole 21 in the correct posture.

[0026] In some embodiments, a contoured positioning groove 106 matching the outer surface of the terminal body 11 is formed in the installation groove 101 to position the terminal body 11 in the installation groove 101 and also to avoid installing the wrong type of terminal body 11 on the fixing seat 10.

[0027] In some embodiments, the two limiting arms 121 are mirror-imaged and arranged on opposite sides of the fixed cover 12. Specifically, the limiting arms 121 include a limiting section 123 and an extension section 124 extending sequentially. The inner side of the limiting section 123 can abut the side of the terminal body 11. The two limiting sections 123 cooperate to fix the relative position of the terminal body 11 and the fixed cover 12. The extension section 124 is bent outward from the connection between it and the limiting section 123, and a first buckle 122 is formed at the far end of the extension section 124. The purpose is to give way to the first buckle 122 to ensure that the first buckle 122 can be buckled into the buckle groove 102, so that the fixed cover 12 is fixed to the fixing seat 10 and holds the terminal body 11 tightly.

[0028] In some embodiments, at least one boss 125 is disposed on the inner side of the fixing cover 12 , and the boss 125 can abut against the side of the terminal body 11 to form a heat dissipation gap between the terminal body 11 and the fixing cover 12 to ensure the heat dissipation performance of the terminal body 11 .

[0029] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
