Description

Technical Field

[0001] This utility model relates to the field of electrical auxiliary equipment, and in particular to a device for mounting terminals. Background Technology

[0002] New energy electric vehicles are equipped with an increasing number of electronic devices, and the in-vehicle circuit system is becoming more and more complex. Among them, relays play an important role in the power distribution and signal control of the entire vehicle circuit. The connection between the male terminal of the relay and the female terminal of the wiring harness enables current transmission, and the four wiring harnesses are led out independently (see Chinese patent document CN218351382U).

[0003] During vehicle operation, relays and wiring harnesses vibrate, causing the female terminals to loosen, resulting in intermittent circuitry and affecting the vehicle's overall electrical control. Furthermore, plugging and unplugging wiring harnesses requires individual operation, which is time-consuming and laborious. To achieve secure terminal connections and facilitate easy insertion and removal, the technical solutions described in Chinese patent document CN220368179U address these problems. However, when the female terminal and locking mechanism are inserted together into the cavity and terminal hole of the housing, and the insertion and removal directions of the female terminal and locking mechanism are aligned with the axial direction of the cavity and terminal hole, vibrations from the vehicle body cause the combined force of multiple wiring harnesses to pull the female terminal axially. The pull-out force of the female terminal forces the locking mechanism to move axially as well, making the locking mechanism easy to unlock and causing the female terminal to loosen or even detach. Summary of the Invention

[0004] In order to overcome the defect in the prior art where the female terminal is easy to fall off because the insertion and removal directions of the locking component and the female terminal are the same, this utility model proposes a terminal mounting module in which the insertion and removal direction of the locking component is perpendicular to the insertion and removal direction of the female terminal, so that the female terminal is securely locked and will not fall off.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a terminal mounting module, comprising a housing and a locking member inserted inside the housing, the housing having multiple through holes for accommodating female terminals, and the housing also having a locking cavity for inserting the locking member, the direction of the locking cavity being perpendicular to and intersecting with the axial direction of the through holes.

[0006] Preferably, the locking member includes an end and a locking arm, the end being connected to the locking arm, and the outer side of the locking arm being provided with at least one flange or protrusion for blocking the female terminal.

[0007] Preferably, the outer side of the locking arm is provided with at least one flange and at least one protrusion, with the flange and protrusion spaced apart from each other.

[0008] Preferably, the end portion comprises two, which are spaced apart and parallel to each other; a tongue is provided between the two ends and is connected to the end portion; a recess is provided on the outer side of the tongue; the lock cavity is divided into a lock channel for inserting the lock arm and an intermediate channel for inserting the tongue, the direction of the lock channel is perpendicular to and intersects the axis of the through hole, and the inner sidewall of the intermediate channel is provided with protrusions corresponding to the recess.

[0009] Preferably, the outer edge of the tongue is provided with a barb, and the inner wall of the middle channel is provided with a groove corresponding to the barb.

[0010] Preferably, the tongue is also provided with a guide rail, and correspondingly, a track is cut out in the middle channel, and the locking member generates linear displacement along the track through the guide rail.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by setting the direction of the locking cavity to be perpendicular to the axis of the terminal through hole, when the female terminal becomes loose, the insertion and extraction force of the female terminal is applied vertically to the locking member in the locking cavity. The locking member blocks the movement of the female terminal and realizes the locking function, so that the female terminal is firmly and securely fixed in the terminal through hole and will not fall off, thus preventing the female terminal from becoming loose and further ensuring the continuous connection of the relay circuit.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; however, this utility model can also be implemented in other ways different from those described herein. Therefore, this utility model is not limited to the specific embodiments disclosed in the following specification.

[0024] like Figure 1 As shown, the terminal mounting module consists of a housing 1 and a locking component 2. The locking component 2 is inserted inside the housing 1. Both the housing and the locking component are made of plastic.

[0025] like Figure 2 and Figure 3 As shown, the housing is generally square, with four through holes 1.1 and one locking cavity 1.2 inside. The through holes accommodate female terminals and wire harnesses, and are arranged vertically. A port 1.3 is located on the front of the housing 1, and port 1.3 communicates with the through holes 1.1. The locking cavity is used to insert the locking component, and is arranged longitudinally, with the direction of the locking cavity perpendicular to the axis of the through holes.

[0026] like Figure 4 As shown, the lock cavity 1.2 consists of a central channel 1.4 and two locking channels 1.5, with the locking channels 1.5 located beside the central channel 1.4. The central channel is used to insert the latch of the lock piece, and the locking channels are used to insert the lock arm of the lock piece. The locking channels 1.5 intersect with the through hole 1.1. A track 1.6 is cut into the central channel 1.4, and protrusions 1.7 and grooves 1.8 are provided on the inner wall of the central channel 1.4. The protrusions restrict the displacement of the lock piece.

[0027] like Figure 5 and Figure 6As shown, the locking element 2 consists of an end piece 2.1, a locking arm 2.2, and a tongue piece 2.3. The locking arms and the tongue piece are spaced apart. The locking arms are used to lock the female terminal, and the tongue piece serves as a guide and limiter. The end piece 2.2 connects two locking arms 2.2 and a tongue piece 2.3. The tongue piece is located in the middle, and the locking arms are located on both sides of the tongue piece and are parallel to each other. The end piece has a transverse layout, while the locking arms and the tongue piece are arranged longitudinally. The direction of the locking arms and the tongue piece is consistent with the direction of the locking cavity. The direction of the locking element and the locking cavity is defined as longitudinal. The outer surface of the locking arm 2.2 is provided with two flanges 2.4, two protrusions 2.5, and four notches 2.6. The two protrusions 2.5 are located between two adjacent notches 2.6. The flanges and protrusions are spaced apart. One flange 2.4 is located at the end piece 2.1, and the other flange 2.4 is located between two notches 2.6. The flanges and protrusions together block the shoulder of the female terminal. The outer edge of the tongue 2.3 is provided with a barb 2.7 and a recess 2.8, and a square hole 2.9 is opened in the middle of the tongue 2.3, which causes a slight deformation of the outer edge of the tongue. The barb 2.7 is close to the end 2.1, and the recess 2.8 is away from the end 2.1. A guide rail 2.10 is provided on one side of the tongue 2.3. The guide rail 2.10 cooperates with the track 1.6 of the locking cavity 1.2, and the locking member 2 is linearly displaced along the track 1.6 through the guide rail 2.10.

[0028] like Figure 7 As shown, the locking element 2 is inserted into the locking cavity 1.2 of the housing 1 and is in a locked state. The tongue 2.3 is inserted into the middle channel 1.4 of the locking cavity 1.2, and the locking arm 2.2 is inserted into the locking channel 1.5 of the locking cavity 1.2. The recess 2.8 of the tongue 2.3 accommodates the protrusion 1.7 of the middle channel 1.4. The protrusion restricts the movement of the locking element, thereby positioning the locking element. The guide rail 2.10 of the locking element 2 is embedded in the track 1.6 of the housing 1.

[0029] like Figure 8 As shown, the lock piece 2 is inserted into the lock cavity 1.2 of the housing 1 and is in the unlocked state. The barb 2.7 of the tongue 2.3 abuts against the groove 1.8 of the middle channel 1.4, and the groove restricts the lock piece from leaving the lock cavity.

[0030] like Figure 9 As shown, the female terminal 5 and the wire harness 4 are inserted into the through hole 1.1 of the housing 1 of the terminal mounting module. The female terminal 5 and the wire harness 4 are connected to the relay 3 through the terminal mounting module. The male terminal 3.1 of the relay 3 is inserted into the female terminal 5.

[0031] like Figure 10 As shown, when the locking member is in the locked position, the flange 2.4 and the protrusion 2.5 of the locking arm 2.2 of the locking member 2 block the shoulder of the female terminal 5, thereby restricting the movement of the female terminal. The insertion and removal direction of the female terminal is axial (vertical), while the movement direction of the locking member is longitudinal. The insertion and removal direction of the female terminal and the movement direction of the locking member are perpendicular to each other, and the female terminal is firmly locked by the locking member.

[0032] like Figure 11 As shown, when the lock is in the unlocked position, the flange 2.4 and the protrusion 2.4 of the locking arm 2.2 of the lock 2 leave the shoulder of the female terminal 5. The female terminal does not encounter any obstruction, so the female terminal is unlocked.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
