[0001] This application relates to the technical field of connectors, and in particular, to a small connector applied to automotive glass. Background Art
[0002] Currently, small connectors generally refer to miniaturized components used for physical and electrical connections inside or between electronic devices. They play a crucial role in modern electronic devices because with the development of technology, devices tend to be miniaturized and lightweight, and the requirements for connectors are also increasing day by day.
[0003] As an important part of a vehicle, automotive glass not only provides vision protection for passengers but also plays a key role in the safety and comfort of the vehicle. The windshield of most vehicles is usually laminated glass and is equipped with electric heating wires, which can be used for rapid defrosting and defogging of the glass. For this reason, corresponding circuits need to be set around the automotive glass to meet the above requirements, and various types of connectors also need to be set on the automotive glass to achieve signal connection between wires.
[0004] In the related art, for small connectors, due to the relatively small space in the welding area of automotive glass electrical components, the connectors used are also relatively small in size. After the female terminal and the male terminal are inserted and fixed to each other, affected by their insertion structure, it is very easy for the two to become detached when subjected to external pulling force, resulting in poor connection reliability between the two. Summary of the Utility Model
[0005] This application provides a small connector applied to automotive glass, which has the effect of not being easily detached due to external pulling force and having a more stable and reliable connection.

The first bending member and the second bending member are both penetrated with locking holes arranged oppositely; the end of the female plug is bent and formed with a plugging groove for the first bending member and the second bending member to be inserted into the female plug; a locking block is arranged on the inner side wall of the plugging groove, and the locking block is used to be inserted into the locking hole to limit the male plug from detaching from the plugging groove; welding members located outside the plugging groove are also arranged on the first bending member and the second bending member, and the male plug is fixedly arranged on the glass through the welding members.
[0008] Preferably, a guiding inclined surface is inclinedly arranged on the side wall of the locking block facing the plugging direction of the male plug; when the male plug is inserted into the plugging groove, the guiding inclined surface is used to guide the locking block to be inserted into the locking hole.
[0009] Preferably, insertion surfaces are provided at the ends of the first bending member and the second bending member away from the welding member, and the insertion surfaces are inclined; the insertion surfaces are used to contact the guiding inclined surfaces and guide the first bending member and the second bending member to cross over the locking block.
[0010] Preferably, the first bending member and the second bending member are also provided with communicating relief holes, and the relief holes are located at the connection between the male plug and the welding member; when the male plug and the female plug are inserted and fixed to each other, the relief holes are located outside the insertion groove.
[0011] Preferably, a crimping block is integrally formed on the inner side wall of the insertion groove, and the locking block is arranged on the crimping block; the crimping block is used to press the male plug against the inner side wall of the insertion groove.
[0012] Preferably, a deformation groove is recessed on the side wall of the crimping block facing away from the insertion groove.
[0013] Preferably, a chamfer is provided on the side wall of the crimping block facing the insertion direction of the male plug.
[0014] In summary, the present application includes at least one of the following beneficial technical effects:
[0015] Through the mutual insertion and cooperation of the locking block and the locking hole, the male plug can be locked on the female plug, effectively preventing the male plug from disengaging from the insertion groove.

Detailed implementation manners
[0022] The present application will be further described in detail below with reference to the accompanying drawings.
[0023] An embodiment of the present application discloses a small connector applied to an automotive glass.
[0024] Referring to Figure 1 and Figure 2 , the small connector applied to the automotive glass includes a male plug 1 and a female plug 2. The male plug 1 includes a first bending member 10 and a second bending member 11 formed by stamping and folding a metal plate or strip. Locking holes 3 are formed through the first bending member 10 and the second bending member 11 and are arranged oppositely. The end of the female plug 2 is bent and formed with an insertion slot 20 for inserting the first bending member 10 and the second bending member 11 into the female plug 2.
[0025] As shown in Figure 2 and Figure 3 , a pressing block 6 is integrally formed on the inner side wall of the insertion slot 20, and a locking block 21 located in the insertion slot 20 is integrally formed on the pressing block 6. The pressing block 6 is used to press the male plug 1 inserted into the insertion slot 20 against the inner side wall of the insertion slot 20. A deformation groove 60 is recessed on the side wall of the pressing block 6 facing away from the insertion slot 20. When the male plug 1 is inserted into the insertion slot 20, the deformation groove 60 can provide a deformation space for the pressing block 6, so as to ensure that the male plug 1 can be smoothly inserted into the insertion slot 20. A chamfer 61 is provided on the side wall of the pressing block 6 facing the insertion direction of the male plug 1, and the setting of the chamfer 61 can further ensure that the male plug 1 is smoothly inserted into the insertion slot 20.
[0026] As shown in Figure 2 and Figure 3 , as the male plug 1 is inserted into the insertion slot 20, the locking hole 3 will gradually approach the locking block 21. When the locking hole 3 moves to be directly opposite to the locking block 21, the locking block 21 will be inserted into the locking hole 3 under the restoring force of the pressing block 6. Through the mutual insertion and cooperation of the locking block 21 and the locking hole 3, the male plug 1 can be locked on the female plug 2, effectively preventing the male plug 1 from disengaging from the insertion slot 20. The connection reliability and firmness when the male plug 1 and the female plug 2 are inserted into each other are improved.
[0027] As shown in Figure 2 and Figure 3As shown, on the side wall of the locking block 21 facing the direction of insertion of the male plug 1 into the insertion slot 20, a guiding inclined surface 22 is inclinedly arranged. When the male plug 1 is inserted into the insertion slot 20, the guiding inclined surface 22 is used to guide the locking block 21 to smoothly insert into the locking hole 3.
[0028] As Figure 2 , Figure 3 shown, a welding part 4 located outside the insertion slot 20 is also fixedly arranged on the first bending part 10 and the second bending part 11. The male plug 1 is fixedly arranged on the glass through the welding part 4. The welding part 4 can further increase the contact area between the male plug 1 and the glass surface, thereby ensuring that the male plug 1 is fixed on the glass more stably and firmly.
[0029] As Figure 2 , Figure 3 shown, insertion surfaces 12 are integrally formed at one ends of the first bending part 10 and the second bending part 11 away from the welding part 4. The insertion surfaces 12 are inclinedly arranged, and the insertion surfaces 12 are used to contact the guiding inclined surface 22 and guide the ends of the first bending part 10 and the second bending part 11 to smoothly cross over the locking block 21.
[0030] As Figure 2 , Figure 3 shown, the first bending part 10 and the second bending part 11 are also penetrated with communicating relief holes 5, and the relief holes 5 are located at the connection between the male plug 1 and the welding part 4. When the male plug 1 and the female plug 2 are inserted and fixed to each other, at this time, the side of the relief hole 5 away from the insertion surface 12 will be located outside the insertion slot 20. The setting of the relief holes 5 facilitates bending the first bending part 10 and the second bending part 11. By appropriately bending the connection between the male plug 1 and the welding part 4, it can better adapt to the installation work in a narrow space.
[0031] The implementation principle is as follows: As the male plug 1 is inserted into the insertion slot 20, the locking hole 3 will gradually approach the locking block 21. When the locking hole 3 moves to be directly opposite to the locking block 21, the locking block 21 will be inserted into the locking hole 3 under the restoring force of the crimping block 6. Through the mutual insertion and cooperation of the locking block 21 and the locking hole 3, the male plug 1 can be locked on the female plug 2, effectively preventing the male plug 1 from disengaging from the insertion slot 20. The connection reliability and firmness when the male plug 1 and the female plug 2 are inserted into each other are improved.
[0032] The welding part 4 can further increase the contact area between the male plug 1 and the glass surface, thereby ensuring that the male plug 1 is fixed on the glass more stably and firmly. The setting of the relief holes 5 facilitates bending the first bending part 10 and the second bending part 11. By appropriately bending the connection between the male plug 1 and the welding part 4, it can better adapt to the installation work in a narrow space and ensure that the male plug 1 can be smoothly installed on the glass.
[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
