Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile electrical connection, in particular to an electrical connection component and a connector. Background Art

Since the temperature sensor is not in direct contact with the terminal, heat transfer will inevitably be lost and delayed to a large extent, resulting in a slow temperature response speed. In addition, the detection accuracy may also be insufficient due to poor fit between the temperature sensor and the terminal, and temperature changes cannot be well monitored. Utility Model Content

[0030] Housing 30 Cable 40 DETAILED DESCRIPTION
[0031] The preferred embodiments of the present disclosure are described below in conjunction with the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present disclosure and are not used to limit the present disclosure. In addition, the embodiments and features in the embodiments of the present disclosure may be combined with each other if no conflict occurs.
[0032] like Figures 1 to 6 As shown, the present disclosure provides an electrical connection assembly according to a preferred embodiment, comprising: a stamped terminal 10 and a temperature sensor 20. The stamped terminal 10 comprises a socket body 101, a transition portion 102 connected to the socket body 101, and a crimping portion 103 connected to the transition portion 102. The transition portion 102 is provided with a snap portion. The temperature sensor 20 is snap-fitted and mounted to the transition portion 102 with the snap portion. The centerline A2 of the temperature sensor 20 intersects the axis A1 of the socket body 101. It is understood that the socket body 101 is used to plug into a matching male terminal, and the crimping portion 103 is used to crimp with one end of the cable 40.
[0033] More specifically, in one embodiment, if Figure 1 As shown, the center line A2 of the temperature sensor 20 is perpendicular to the axis A1 of the jack body 101. It can be understood that in other embodiments, such as Figure 2 and Figure 3 As shown, the centerline A2 of the temperature sensor 20 can be arranged at an acute angle or an obtuse angle with the axis A1 of the jack body 101. In the present disclosure, the installation angle of the temperature sensor 20 can be determined based on the actual installation conditions of the stamped terminal 10, thereby enhancing the compatibility of the installation between the temperature sensor 20 and the stamped terminal 10.
[0034] Specifically, if Figure 4 As shown, the transition portion 102 is configured as a semi-open receiving cavity, and the locking portion is configured as a pair of spring tabs 104 stamped from the two side walls of the receiving cavity. The spring tabs 104 are bent to clamp the temperature sensor 20. Thus, the temperature sensor 20 is installed by clamping with the spring tabs 104, which also facilitates subsequent installation and removal of the temperature sensor 20.
[0035] More specifically, the extension direction of the spring 104 is parallel to the center line A2 of the temperature sensor 20. It can be understood that Figures 1 to 3 In the three different installation methods shown, the extension direction of the spring piece 104 is parallel to the center line A2 of the temperature sensor 20. This facilitates forming the corresponding spring piece 104 when stamping the terminal 10.
[0036] More specifically, if Figure 4 As shown, additional spring pieces 105 extend from both sides of the bent end of the spring piece 104, and the paired additional spring pieces 105 are arranged circumferentially around the temperature sensor 20. Thus, the temperature sensor 20 can be more firmly mounted on the transition portion 102 of the stamped terminal 10.
[0037] In some embodiments, as Figures 5 and 6 As shown, the butt end of the jack body 101 is divided into a plurality of first elastic arms 106 by an axially extending slot, and a metal cylinder 108 is sleeved on the butt end. The metal cylinder 108 has second elastic arms 107 opened one by one at the positions corresponding to the plurality of first elastic arms 106. The free end of each first elastic arm 106 protrudes out of the opening on the metal cylinder 108 for opening the second elastic arm 107 and abuts against the butt edge of the metal cylinder 108.
[0038] More specifically, the plurality of second elastic arms 107 are embedded and extend toward the axis of the metal cylinder 108 , and the free end of each second elastic arm 107 abuts against the free end of the corresponding first elastic arm 106 .
[0039] Thus, the second elastic arm 107 can press the first elastic arm 106, providing a certain positive pressure to the docking end of the stamping terminal 10, which can effectively maintain the stability of the plugging and unplugging force of the socket body 101 of the stamping terminal 10, and the first elastic arm 106 abuts against the docking edge of the metal cylinder 108 and is clamped between the docking edge and the second elastic arm 107, which can effectively prevent the metal cylinder 108 from falling off from the docking end of the stamping terminal 10.
[0040] Another aspect of the present disclosure provides a connector comprising
[0041] housing 30, and
[0042] According to the electrical connection assembly described in any of the above embodiments, the electrical connection assembly is inserted into the housing 30 .
[0043] According to the electrical connection assembly and connector disclosed herein, the temperature sensor is directly mounted on the transition portion of the stamped terminal through the snap-fit portion, which not only shortens the heat transfer distance between the temperature sensor and the stamped terminal, but also facilitates installation and disassembly; and the center line of the temperature sensor is arranged to intersect with the axis of the jack body, thereby enhancing the adaptability of the installation between the temperature sensor and the stamped terminal.
[0044] Although the preferred embodiments of the present disclosure have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concepts. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present disclosure.
[0045] Obviously, those skilled in the art may make various changes and modifications to the embodiments of the present disclosure without departing from the spirit and scope of the embodiments of the present disclosure. Thus, if such changes and modifications of the embodiments of the present disclosure fall within the scope of the claims of the present disclosure and their equivalents, the present disclosure is intended to include such changes and modifications.
[0046] It should also be understood that in the embodiments herein, the term "and / or" merely describes an association between associated objects, indicating that three possible relationships exist. For example, "A and / or B" could represent: A alone, A and B simultaneously, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

The description of the above embodiments is only used to help understand the methods and core ideas of this article. At the same time, for those skilled in the art, based on the ideas of this article, there will be changes in the specific implementation methods and application scope.
