[0002] At present, with the development of the new energy vehicle industry, the sales of new energy vehicles continue to rise. Various car manufacturers are competing to produce and launch various new models and update their products. However, as demand continues to rise, competition increases, profits decrease, and cost reduction follows. Therefore, a simple structure is required to achieve automation and modular production to achieve the goal of efficient production, so as to control costs while ensuring reliable quality.

[0003] The vehicle sockets in the prior art generally have two structural forms.

[0004] The main processes corresponding to the first structural form are as follows: cutting the cable and stripping off the insulation layer at the cable end → crimping the cable and the copper contact terminal (the copper contact terminal is used to be inserted by the plug pin) → attaching the temperature sensor to the corresponding copper contact terminal → installing the copper contact terminal into the socket body and locking it → then inserting the seals → installing and fixing the socket body.

[0005] The main processes corresponding to the second structural form are as follows: cutting the cable and stripping off the insulation layer at the cable end → assembling the electronic components on the electrical adapter board or PCB board → installing the electronic components and adding various matching structural parts to fix them to the socket body → then inserting the seals respectively → installing and fixing the socket body.

[0006] The first structural form has a complicated assembly process and a large number of fixed structural parts.

DETAILED DESCRIPTION

[0028] The utility model is further described below in conjunction with the accompanying drawings.

[0029] The utility model has an efficient assembly vehicle socket structure, such as Figures 1 to 6 As shown, it includes a socket body 1, in which a socket conductive terminal 4 is arranged, the front part of the socket conductive terminal 4 is a cylindrical structure, the rear end of the socket conductive terminal 4 is closed, and the front part of the socket conductive terminal 4 is used to adapt to the pin of the charging plug to insert and connect, so as to achieve electrical connection. Figures 1 to 6As shown, the vehicle socket structure of the utility model further includes a cable assembly 3, the cable assembly 3 includes a cable 31 and a cable terminal 32, and the end of the cable 31 is conductively connected to the cable terminal 32. Specifically, as shown in FIG. Figure 7 and Figure 8 As shown, the cable terminal 32 is a sheet metal structure, and the cable terminal 32 is formed with a conductive clamp 322. The end of the cable 31 is stripped of the insulation layer to form a bare wire end 311. The conductive clamp 322 clamps the bare wire end 311, thereby forming a reliable conductive connection. Figures 6 to 8 As shown, the front end of the cable terminal 32 is formed with an elastic contact portion 321, and the rear end of the socket conductive terminal 4 is formed with a terminal bottom surface 401, as shown in FIG. Figure 2 and Figure 3 As shown, the elastic contact portion 321 contacts and connects the corresponding terminal bottom surface 401; Figure 1 and Figure 2 As shown, the vehicle socket structure of the utility model also includes a rear cover shell 2, such as Figure 5 As shown, a cable jack 201 is formed in the rear cover shell 2. Figure 2 and Figure 4 As shown, the cable terminal 32 is disposed in the corresponding cable jack 201, as shown in FIG. Figure 1 and Figure 2 As shown, the rear cover shell 2 is adapted to be covered on the rear end of the socket body 1. Relatively, the rear end of the socket body 1 is inserted into the bottom of the rear cover shell 2, and the rear cover shell 2 is buckled with the protrusions on the outer wall of the socket body 1, thereby fixing the socket body 1 and the rear cover shell 2.

[0030] The cable 31 and the socket conductive terminal 4 of the utility model are not rigidly connected, but the cable 31 and the socket conductive terminal 4 are (indirectly) contact-connected, so the cable assembly 3 can be pre-made, and in the process of assembling the vehicle socket, the cable 31 of each cable assembly 3 can be passed through the cable jack 201, and then the cable terminal 32 is inserted from front to back into the corresponding cable jack 201, and the cable terminal 32 and the rear cover shell 2 are assembled into an assembly module; each socket conductive terminal 4 is respectively inserted into the socket body 1 to form an assembly module, avoiding obstruction of the cable 31 during the installation of the socket conductive terminal 4, so that the socket conductive terminal 4 can be quickly and accurately installed in place, which is beneficial to the conductivity of the vehicle socket and the charging plug. The connection is good, and since the process of inserting each socket conductive terminal 4 will not be hindered by the cable 31, it is convenient to use automated equipment to insert the socket conductive terminal 4 into the socket body 1, which is conducive to improving assembly efficiency and reducing labor costs; in the final assembly process, it is only necessary to install and connect the rear cover shell 2 with the socket body 1, so that each elastic contact part 321 can contact and connect the corresponding terminal bottom surface 401, that is, modular assembly is conducive to improving assembly efficiency, and then the elastic contact part 321 maintains an elastic deformation state, and the conductive connection of all cables 31 and the corresponding socket conductive terminal 4 can be completed at the same time, that is, the elastic contact structure is used to optimize the transition connection between the socket conductive terminal 4 and the cable 31. The cable assembly 3 can be assembled by an automated terminal crimping machine to achieve precision and efficiency. The elastic restoring force of the elastic contact portion 321 is applied to the corresponding terminal bottom surface 401, which is conducive to making the cable terminal 32 and the socket conductive terminal 4 have good conductive contact, and improves the tolerance of the parts of the vehicle socket. For example, if there is an error in the socket body 1 and the terminal bottom surface 401 is offset forward, the elastic contact portion 321 is elastically deformed to contact the terminal bottom surface 401, so the above error can be offset. Since the vehicle socket structure of the utility model avoids the need to use an electrical adapter board or a PCB board structure, the material cost of the vehicle socket structure of the utility model is relatively low.

[0031] Furthermore, if Figure 7 As shown, the elastic contact portion 321 is arranged in an arch shape, so that the front end of the arch contacts the bottom surface 401 of the terminal, and the rear end of the arch is connected to the body of the cable terminal 32 as a whole, which can also be understood as follows. Figure 3 As shown, the elastic contact portion 321 is in the shape of an inverted English letter "U". When the elastic contact portion 321 undergoes elastic deformation, it is equivalent to the elastic narrowing of the opening of the "U" shape. The above-mentioned elastic contact portion 321 has a simple structure, is easy to manufacture, and has a strong elastic deformation ability.

[0032] Furthermore, if Figure 5 As shown, a card slot 2011 is formed at the front end of the cable jack 201. Figure 8As shown, the cable terminal 32 is formed with a positioning head 324, which is made by folding a flat plate structure, and the rear end of the elastic contact portion 321 is connected to the front end of the positioning head 324 as a whole, as shown in FIG. Figure 4 and Figure 5 As shown, the positioning head 324 is adapted to be inserted into the slot 2011, so that when the cable terminal 32 is inserted backward into the cable jack 201, as the positioning head 324 is inserted into the bottom of the slot 2011, the cable terminal 32 is blocked and limited, and the slot 2011 also prevents the cable assembly 3 from rotating, thereby reliably positioning the cable assembly 3 and preventing the elastic contact portion 321 from shifting when the cable 31 is pulled backward.

[0033] Furthermore, if Figure 6 and Figure 7 As shown, the cable assembly 3 includes a sealing sleeve 33, and the sealing sleeve 33 is adapted to be arranged outside the cable 31. Figure 2 and Figure 3 As shown, the sealing sleeve 33 is arranged in the cable socket 201, so the sealing sleeve 33 closes the gap between the inner wall of the cable socket 201 and the insulating layer of the cable 31, preventing water from entering the inner cavity of the vehicle socket from the rear side of the vehicle socket, which is beneficial to the safety of electricity use. During this period, the sealing sleeve 33 can include three convex rings, and the three convex rings elastically contact the inner wall of the cable socket 201 respectively to form a multi-level water retaining structure. The sealing sleeve 33 can be made of silicone rubber.

[0034] Furthermore, if Figure 8 As shown, the cable terminal 32 is formed with a wire holding portion 323, as shown in FIG. Figure 7 As shown, the front end of the sealing sleeve 33 is clamped between the cable 31 and the wire holding portion 323, so that the conductive clamp 322 is located at the front side of the wire holding portion 323, and the conductive clamp 322 is located at the rear side of the positioning head 324. It should be noted that Figure 7 The wire gripping portion 323 and the conductive clamping portion 322 are only shown in the unwrapped state (i.e., the open state). The wire gripping portion 323 is used to simultaneously fix the cable 31 (including the insulating layer) and the sealing sleeve 33 to the cable terminal 32, which helps to simplify the assembly process.

[0035] Furthermore, if Figure 2 and Figure 4 As shown, the vehicle socket structure of the utility model also includes a temperature sensor assembly 5, such as Fig. 9 As shown, the temperature sensor assembly 5 includes a sensor connecting wire 501, a temperature sensing element, and a housing 51 for abutting against the rear end of the power transmission socket 6. The housing 51 seals and covers the end of the sensor connecting wire 501 and the temperature sensing element. The housing 51 can be integrally formed by a low-pressure injection molding process using silicone rubber. Figure 5 As shown, a positioning groove 202 is formed in the rear cover shell 2. Figure 4As shown, the capsule 51 is inserted into the corresponding positioning groove 202 from front to back, thereby preventing the capsule 51 from shifting. Figure 2 As shown, the vehicle socket structure includes a power transmission socket 6 and a power transmission line 7. The end of the power transmission line 7 is welded to the rear end of the power transmission socket 6. The shell 51 is attached to one side of the rear end of the power transmission socket 6. The power transmission line 7 is used to transmit the charging current. Therefore, during the charging process, the power transmission socket 6 will generate a large amount of heat. The above heat is transferred to the temperature sensing element through the shell 51, so that the temperature sensing element can monitor the temperature of the power transmission socket 6. The shell 51 has the function of sealing and waterproofing, simplifies the assembly process, and is conducive to more sensitive and reliable temperature sensing; avoid the use of the traditional structure of fixing the temperature sensing element to the monitoring point by binding, which has a complex process and is easy to fall off, and the temperature feedback is not sensitive.

[0036] Furthermore, if Fig. 9 As shown, the outer portion of the enclosure 51 is formed with a transverse rib 511 for contacting and connecting the inner wall of the positioning groove 202, so when the enclosure 51 is inserted into the positioning groove 202, the transverse rib 511 is substantially perpendicular to the insertion direction, and the transverse rib 511 is relatively squeezed by the inner wall of the positioning groove 202, which significantly increases the friction between the enclosure 51 and the inner wall of the positioning groove 202, which is conducive to the stable installation of the enclosure 51. Thermal conductive silicone grease can be provided between the enclosure 51 and the power transmission socket 6, which is conducive to heat transfer and reliable monitoring of the temperature sensor assembly 5.

[0037] like Figure 2 and Figure 3 As shown, the vehicle plug-in structure also includes an inner pressure cover 8, which is clamped between the socket body 1 and the rear cover shell 2. First, the power transmission line 7 is passed through the rear cover shell 2, and then the card gap of the inner pressure cover 8 is clamped to the power transmission socket 6, and the power transmission socket 6 is inserted into the socket body 1. Then, the socket body 1 and the rear cover shell 2 are assembled together, and the inner pressure cover 8 is clamped and positioned. Figure 2 As shown, after assembly is completed, the inner pressure cover 8 is against the bottom surface 401 of the terminal, and the inner pressure cover 8 is against the front end of the sealing shell 51, thereby preventing the sealing shell 51, the power transmission socket 6 and the socket conductive terminal 4 from shifting forward and backward.

[0038] For example, all electrode cable assemblies and electronic components with a current less than 10A can be installed in the rear cover shell 2 to facilitate modular assembly.

[0039] In summary, the advantages of the vehicle socket structure of the utility model are:

[0040] (1) It is conducive to improving the degree of automated production and reducing labor costs.

[0041] (2) Simple structure, easy assembly and low material cost.

[0042] (3) To facilitate "modular" assembly production, it is efficient and flexible with low labor costs.
