Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a position holding device and a connector assembly. Background Art

[0002] With the rapid rise and popularization of new energy vehicles, the types of various vehicle connectors are gradually increasing. With the continuous maturity of technology, the performance requirements for connectors are also continuously improved and gradually increased; the connector position assurance (CPA) is an essential functional structure, which can effectively improve the vibration performance and other functional reliabilities of the connector.

[0003] For example, the position holding device provided by Chinese Patent CN219350867U includes a frame-shaped main body, an auxiliary pressing feature arranged inside the frame-shaped main body. By pressing the auxiliary pressing feature, the unlocking of the male and female ends of the connector can be realized, and guiding grooves arranged on both sides of the frame-shaped main body. Groove / protrusion features for positioning the pre-installed position and the locked position of the position holding device are arranged on the inner wall of the guiding grooves. By pushing the position holding device, its position switching on the female end can be realized. When it is necessary to unlock the male and female ends, first, it is necessary to push the position holding device in the reverse direction to switch the position holding device from the locked position to the pre-installed position, and then press the auxiliary pressing feature to unlock the male and female ends. With the miniaturization of the connector, whether it is the process of pushing the position holding device or the process of pressing the auxiliary pressing feature, the force actually applied by the operator is concentrated on the auxiliary pressing feature. Such a design has a poor operating feel, and when the operator applies a large force, there is also a risk of direct separation of the male and female ends, resulting in a decrease in safety. Summary of the Utility Model

[0004] In view of this, the purpose of the present utility model is to provide a position holding device and a connector assembly to solve the technical problems mentioned in the background art.

[0005] In order to achieve the above purpose, the technical solution adopted by the present utility model is: a position holding device, which is slidably arranged on the connector and has a pre-installed position and a locked position.

Clamping plates that can be flipped relative to the main body are symmetrically arranged on both sides of the main body, and locking features for locking the sliding position of the position holding device are arranged on the clamping plates.

[0006] In some embodiments, sliding grooves that are slidably matched with the connector are further arranged on both sides of the main body.

[0007] In some embodiments, the locking feature is a locking hole, and a locking post is provided on the connector and is adapted to the locking hole. When the position holding device is in the locked position, flipping the buckle plate can cause the locking post to be snapped into the locking hole.

[0008] In some embodiments, the locking hole is a through hole or a blind hole.

[0009] In some embodiments, at least one limiting bump protrudes from the bottom of the main body, and a limiting sliding groove that is slidably engaged with the limiting bump is provided on the connector. When the position holding device is in the pre-installed position and the locked position, the limiting bump abuts against the first end and the last end of the limiting sliding groove respectively.

[0011] A connector assembly of the present utility model includes a connector and the above-mentioned position holding device. The position holding device is slidably disposed on the connector and has a pre-installed position and a locked position.

[0012] In some embodiments, sliding grooves are further provided on both sides of the main body, and sliding rails that are slidably engaged with the sliding grooves are provided on the connector.

[0013] In some embodiments, the locking feature is a locking hole, and a locking post that is adapted to the locking hole is provided on the side wall of the sliding rail. When the position holding device is in the locked position, flipping the buckle plate can cause the locking post to be snapped into the locking hole.

[0014] In some embodiments, at least one limiting bump protrudes from the bottom of the main body, and a limiting sliding groove that is slidably engaged with the limiting bump is provided on the connector. When the position holding device is in the pre-installed position and the locked position, the limiting bump abuts against the first end and the last end of the limiting sliding groove respectively.

It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present invention.

[0027] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way a limitation on the present invention or its application or use.

[0028] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the specification.

[0029] In all the examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0030] A position holding device is slidably disposed on the connector 2 and has a pre-installed position and a locked position. Figure 2and Figure 3 Schematic diagrams of the state of the position holding device when it is in the pre-installed position and the locked position respectively; further, as Figure 1 As shown, the position holding device 1 includes a frame-shaped main body 10 and an auxiliary pressing feature 20 arranged on the inner side of the main body 10. It should be noted that the frame-shaped main body 10 and the auxiliary pressing feature 20 arranged on the inner side of the main body are relatively conventional prior arts in the field and will not be described in detail here. For details, please refer to Chinese patent CN219350867U. The main improvement of the utility model is to improve the existing guide grooves arranged on both sides of the frame-shaped main body and the grooves / protrusions arranged on the inner wall of the guide grooves for positioning the pre-installed position and the locked position of the position holding device, so as to optimize the operating feel and avoid the risk of direct separation of the male end and the female end due to the operator's strong force, and the safety is effectively improved, as follows:

[0031] like Figure 1 As shown, the position holding device 1 of the present invention is symmetrically provided with buckle plates 30 that can be flipped relative to the main body 10 on both sides of the main body 10, and the buckle plates 30 are provided with locking features that can lock the sliding position of the position holding device 1. Specifically, the locking feature is a locking hole 301, and the locking hole 301 is a through hole or a blind hole. Correspondingly, as shown in FIG. Figure 4 As shown, the connector 2 is provided with a locking column 4 that matches the locking hole 301. When the position holding device 1 is in the locking position, the locking column 4 can be locked in the locking hole 301 by flipping the buckle plate 30. That is, the sliding position of the position holding device 1 on the connector can be locked by the buckle plate 30, so that when the position holding device 1 needs to be pushed in the reverse direction, it is only necessary to flip the buckle plate 30 in advance to separate the position holding device 1 from the connector, and it is no longer necessary to apply a large force to the position holding device 1, thereby optimizing the operating feel and avoiding the risk of direct separation of the male end and the female end due to the operator's large force, thereby effectively improving the safety.

[0032] In one embodiment, if Figures 1-4 As shown, both sides of the main body 10 are also provided with slide grooves 101 that slide with the connector 2, and the connector 2 is provided with slide rails 3 that slide with the slide grooves 101. The locking column 4 is specifically arranged on the side walls of the slide rails 3. When the position holding device 1 is installed on the connector 2, the slide grooves 101 arranged on both sides of the main body 10 are embedded in the slide rails 3, and the position holding device 1 can slide freely on the slide rails 3. When it is necessary to lock the sliding position of the position holding device 1, the flip buckle plate 30 can make the locking column 4 clamped in the locking hole 301, thereby realizing effective locking of the position holding device 1.

[0033] Furthermore, if Figures 1-4As shown, in order to limit the extreme installation position of the position holding device 1 on the connector 2, at least one limiting bump 102 is protrudingly provided at the bottom of the main body 10, and a limiting chute 5 that slidably cooperates with the limiting bump 102 is provided on the connector 2. When the position holding device 1 is in the pre-installed position and the locked position, the limiting bump abuts against the first end and the last end of the limiting chute 5 respectively, so as to limit the installation position of the position holding device 1 on the connector 2, prevent the position holding device 1 from falling off the connector 2 when in the pre-installed position, and prevent damage to the position holding device 1 and the connector 2 caused by excessive pushing when the position holding device 1 is pushed from the pre-installed position to the locked position.

[0034] In one embodiment, the buckle plate 30, the auxiliary pressing feature 20 and the main body 10 are integrally injection molded, so as to reduce the manufacturing cost of the position holding device 1 of the present utility model.

[0035] The present utility model further provides a connector assembly, as Figure 2 and Figure 3 shown, including the connector 2 and the above-mentioned position holding device 1. The connector assembly of the present utility model can lock the sliding position of the position holding device 1 on the connector through the buckle plate 30. Thus, when it is necessary to push the position holding device 1 in the reverse direction, only need to flip the buckle plate 30 in advance to separate the position holding device 1 from the connector, without the need to apply a large force to the position holding device 1, so as to optimize the operation feel and avoid the risk of direct separation of the male end and the female end caused by the operator applying a large force, and effectively improve the safety.
