Abstract
Description
Technical Field
[0001] This utility model relates to the field of electromagnetic valve technology, and in particular to a guide self-fixing terminal and mounting base. Background Technology
[0002] Solenoid valves are a common switching control component in vehicles. The coil winding of a solenoid valve is typically wound around an injection-molded mounting base, on which mounting pin terminals are inserted.
[0003] For example, 4. Figure 5 As shown, this is a commercially available pin terminal 3 and mounting base 4. The pin segment is L-shaped and is inserted into the pre-drilled terminal socket on the mounting base 4 from the rear end. During assembly, the tail of the pin terminal 3 needs to be clamped. Due to the short clamping part, the clamping stability is poor, and sometimes the pin terminal 3 will wobble, causing damage to the terminal socket on the mounting base 4. This results in the subsequent terminal socket not being able to fix the pin terminal 3, causing the pin terminal 3 to shake. Consequently, the insertion holding force does not meet the requirements. When winding the enameled wire, the pin terminal 3 will wobble (5 turns). The tension applied during the winding action will exacerbate the up-and-down and left-and-right swaying of the pin terminal 3, causing the terminal to back up and further exacerbate the insufficient holding force. This can easily lead to the scrapping of the wound product and the breakage of the enameled wire, thereby affecting product quality and corporate profits.
[0004] Therefore, it is necessary to provide a guide-type self-fixing terminal and a mounting base to solve the above-mentioned technical problems. Utility Model Content
[0005] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a guide self-fixing terminal and mounting base that can help improve product quality.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: The self-fixing guide terminal includes: a pin terminal body, on which a customer mating end, an injection molded part usage end, and a functional connection end are provided; the functional connection end is bent at a 90-degree angle and located at the tail of the pin terminal body.
[0007] Preferably, the edges of the injection molded part at the usable end are chamfered.
[0008] Preferably, the edges of the functional end are chamfered.
[0009] A mounting base adapted to a pin terminal body includes: a mounting base body, on which a plug socket is integrally provided, and the plug socket has a guide fixing groove and an insertion hole.
[0010] Preferably, the number of sockets is two.
[0011] Preferably, the openings of the guide fixing groove and the insertion hole are chamfered.
[0012] Compared with the prior art, the present invention has the following beneficial effects: (1) By setting up a pin terminal body including a customer pairing end, an injection molded part usage end and a functional connection end, and by designing the injection molded part usage end and the functional connection end separately, and changing the front insertion installation of the pin terminal to the rear insertion installation, the clamping stability and connection stability of the pin terminal body are increased, which can effectively reduce the possibility of the mounting seat being damaged by insertion, and thus help improve product quality. (2) By chamfering the edges of the injection molded part's use end and the functional use end, this utility model can help improve product quality. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments. Example
[0016] like Figure 1-3 As shown, this utility model provides a guide-type self-fixing terminal and a mounting base. The guide-type self-fixing terminal includes: a pin terminal body 1, on which a customer mating end 11, an injection molded part usage end 12, and a functional connection end 13 are provided. The customer mating end 11 is located on the front side of the pin terminal body 1, and its end is a pointed tip. The injection molded part usage end 12 is located at the tail of the pin terminal body 1 and is used to insert into the injection molded mounting base. The functional connection end 13 is also located at the tail of the pin terminal body 1 and is bent at 90 degrees. It is also inserted into the injection molded mounting base.
[0017] Furthermore, the mounting base includes a mounting base body 2, which is paired with the pin terminal body 1. It is made of plastic and is used for winding the coil in the solenoid valve. Specifically, the mounting base body 2 has an integrally formed plug-in seat 21, which has a guide fixing groove 22 and an insertion hole 23. The guide fixing groove 22 matches the functional end 13, and the insertion hole 23 matches the injection molded part's user end 13. There are two plug-in seats 21, used for mounting two pin terminal bodies 1.
[0018] In use, the injection-molded end 12 and functional connection end 13 at the tail of the pin terminal body 1 are inserted into the mounting base in the solenoid valve. Compared with the traditional method where both the pin terminal 3 and the mounting base 4 are inserted, this method clamps the front end of the pin terminal body 1, inserts the injection-molded end 12 into the insertion hole 23 on the mounting base body 2, and continues to move backward, so that the functional end 13 is inserted into the guide fixing groove 22 on the mounting base body 2. During insertion, the clamping part of the pin terminal body 1 is longer, which makes it less likely to cause the pin terminal body 1 to wobble, and the insertion sides of the injection-molded end 12 and the functional end 13 are relatively smooth. Compared to the tip of the pin terminal 3, it is less likely to damage the insertion hole 23 and guide fixing groove 22 of the mounting body 2. The guide fixing groove 22 helps to fix the pin terminal body 1 (the functional end 13 is fixed in the guide fixing groove 22), which strengthens the connection stability between the pin terminal body 1 and the mounting body 2, thereby meeting the requirements of pin holding force. When winding enameled wire, the tension applied by the winding action will not cause the pin terminal body 1 to shake or move back, thus ensuring that the insertion holding force meets the requirements and ensuring the quality of the winding product. This is conducive to improving product quality, reducing scrap, and thus improving efficiency.
[0019] By setting up a pin terminal body 1 that includes a customer pairing end 11, an injection molded part usage end 12, and a functional connection end 13, and by designing the injection molded part usage end 12 and the functional connection end 13 separately, and changing the front insertion type of the pin terminal to the rear insertion type, the clamping stability and connection stability of the pin terminal body 1 are increased, which can effectively reduce the possibility of the mounting seat being damaged by insertion, thereby helping to improve product quality. Example
[0020] like Figure 1 As shown, the edges of the injection molded part's user end 12 and functional user end 13 are chamfered, and the openings of the guide fixing groove 22 and the insertion hole 23 are also chamfered. This reduces the possibility of damage to the insertion hole 23 and the guide fixing groove 22 when the injection molded part's user end 12 is inserted into the insertion hole 23, and when the functional user end 13 is inserted into the guide fixing groove 22, which helps to improve product quality.
[0021] By chamfering the edges of the injection molded part's user end 12 and functional user end 13, product quality can be improved.
[0022] Working principle: During use, the injection-molded end 12 and functional connection end 13 at the tail of the pin terminal body 1 are inserted into the mounting base in the solenoid valve. Compared with the traditional method where both the pin terminal 3 and the mounting base 4 are inserted, this method clamps the front end of the pin terminal body 1, inserts the injection-molded end 12 into the insertion hole 23 on the mounting base body 2, and continues to move backward, so that the functional end 13 is inserted into the guide fixing groove 22 on the mounting base body 2. During insertion, the clamping part of the pin terminal body 1 is longer, which makes it less likely to cause the pin terminal body 1 to wobble, and the insertion sides of the injection-molded end 12 and the functional end 13 are smoother. The slippery surface (compared to the tip of the pin terminal 3) makes it less likely to damage the insertion hole 23 and guide fixing groove 22 of the mounting body 2. The guide fixing groove 22 helps to fix the pin terminal body 1 (the functional end 13 is fixed in the guide fixing groove 22), which strengthens the connection stability between the pin terminal body 1 and the mounting body 2, thereby meeting the requirements of pin holding force. When winding enameled wire, the tension applied by the winding action will not cause the pin terminal body 1 to shake or move backward, thus ensuring that the insertion holding force meets the requirements and ensuring the quality of the winding product. This is conducive to improving product quality, reducing scrap, and thus improving efficiency.
