Description

Technical Field

[0001] The utility model belongs to the technical field of electrical connectors, and particularly relates to a connector with a locking piece. Background Art

[0002] Electrical connectors are widely used. For special scenarios, suitable connectors need to be matched. Currently, connectors with a pitch of 2.0 mm do not have a locking piece assembly, and the terminal retention force is low. Existing side-mounted locking piece connectors have a complex structure, low manufacturing efficiency, high manufacturing cost, and the outer width dimension exceeds the customer requirements. As shown in Figure 1 and Figure 2 the existing side-mounted locking piece connector is shown. Since the side of the locking piece is provided with a connecting portion and also includes a clamping portion, the overall size of the locking piece is large and it cannot adapt to a narrow space. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is how to reduce the product size, especially in the width direction.

[0004] To achieve the above object, the utility model provides the following technical solutions:

[0005] A connector with a locking piece, comprising a pin socket and a connector sheath that are inserted and matched with each other. The connector sheath includes a sheath body and a locking piece. A space for the locking piece to be embedded is provided at the bottom of the sheath body, and the bottom of this space is open. The locking piece is inserted from the bottom of the sheath body, and the locking piece is clamped and matched with the sheath body.

[0006] Preferably, the locking piece includes a blocking portion, and the locking piece is provided with a blocking portion for preventing the terminal from slipping out corresponding to each terminal chamber on the sheath body.

[0007] Preferably, the depth of the space of the sheath body for the locking piece to be embedded is greater than or equal to the height of the locking piece, so that the locking piece does not protrude from the outer surface of the sheath body after being clamped into the space of the sheath body.

[0008] Preferably, buckles are provided at both ends of the locking piece in the length direction, and clamping positions for the buckles on the locking piece to be clamped into are provided at both ends of the space of the sheath body.

[0009] Preferably, the buckle is provided on one side of the end of the locking piece in the length direction, and a notch for the position where the buckle is located to contract inward is provided inside the locking piece on the inner side of the buckle.

[0010] Preferably, barbs are provided on the terminal, an elastic tongue piece extending into the terminal chamber and blocking the terminal from retracting when the terminal is inserted into the terminal chamber is provided on the sheath body, and a tool hole for facilitating the touching of the barb or the elastic tongue piece is provided on one side of the sheath body.

[0011] Preferably, the clamping position is a long groove in the horizontal direction, and the corresponding buckle is also strip-shaped.

[0012] Preferably, the long groove is a through groove communicating inside and outside.

[0013] Preferably, the lock piece is integrally injection-molded from a plastic material.

[0014] The beneficial effects of the present utility model are as follows: the lock piece of the present utility model is arranged at the bottom, so that there are baffles on both sides of the lock piece to protect the lock piece and prevent the lock piece from turning outwards or being accidentally unlocked. By placing the lock piece at the bottom of the sheath body, the size of the sheath body can be made smaller, so that the final external dimensions of the sheath body and the needle seat can meet the size requirements of customers.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0022] Please refer to Figures 3 - 6The figure shows a connector with a locking plate, including a needle hub 1 and a connector cover that are pluggable with each other. The cover cooperates with the needle hub 1 to achieve the functions of assembly, fixing, and unlocking. The needle hub 1 can cooperate with the wire end connector to connect the circuit and signal. This structure is prior art and will not be elaborated in detail here. The needle hub 1 has an undercut that can cooperate with the lock of the cover. This is an internal lock structure that can provide greater locking force, is more stable, and has a lower possibility of mislocking. The connector cover includes a cover body 2 and a locking plate 3. The bottom of the cover body 2 is provided with a space 21 for the locking plate 3 to be embedded, and the bottom of the space 21 is open. The locking plate 3 is installed from the bottom of the cover body 2 and is snap-fitted with the cover body 2. The cover body 2 has cavities corresponding to the number of applied positions, in this example, 5 positions, for installing terminals 4. The bottom surface of the cover body 2 is grooved to connect the various cavities and provide installation space for the locking plate 3. The locking piece 3 includes a stop portion 31. Each terminal cavity on the sheath body 2 is provided with a stop portion 31 to prevent the terminal from sliding out. In this embodiment, the locking piece 3 is arranged at the bottom, so that there are baffles on both sides of the locking piece to protect the locking piece and prevent the locking piece from turning outward or being locked incorrectly. In this embodiment, the locking piece 3 is divided into the same number of positions as the mating sheath by connecting ribs 32, and the connecting ribs 32 also have a supporting function. In this embodiment, by placing the locking piece 3 at the bottom of the sheath body 2, the size of the sheath body 2 can be made smaller, so that the final external dimensions of the sheath body 2 and the needle seat 1 can meet the customer's size requirements. The locking piece 3 in this embodiment is made of plastic material and is integrally injection molded.

[0023] The depth of the space in the sheath body 2 for the locking piece 3 to be embedded is greater than or equal to the height of the locking piece 3 , so that the locking piece 3 does not protrude from the outer surface of the sheath body 2 after being inserted into the space in the sheath body 2 .

[0024] The locking piece 3 is provided with a snap 33 at both ends of the length direction, and the space of the sheath body 2 is provided with a snap position 22 for the snap 33 on the locking piece 3 to snap into. The snap position 22 is a long horizontal groove, and the corresponding snap 33 is also in the shape of a long strip. The long groove is a through groove that communicates inside and outside. The hook-shaped features on both sides of the locking piece 3 can cooperate with the left and right grooves on the sheath body 2. The sheath has grooves on the left and right sides for the locking piece 3 to hook, which plays the role of fixing the locking piece 3 and preventing it from falling off. The function of the long groove can also prevent the locking piece 3 from rotating in the sheath body 2, so that the locking piece 3 can better lock the terminal.

[0025] The buckle 33 is located on one side of the lengthwise end of the locking plate 3, and a notch 34 is provided on the inner side of the locking plate 3 to allow the buckle to retract inward. The notches 34 on both sides of the locking plate 3 provide space and flexibility for the buckles on both sides, allowing the locking plate 3 to be installed and removed from the protective cover body 2.

[0026] The terminal 4 is provided with a barb 41, and the housing body 2 is provided with an elastic tongue 23 that extends into the terminal cavity and prevents the terminal from retracting when inserted into the cavity. A tool hole is provided on one side of the housing body 2 to facilitate access to the barb or elastic tongue. Each cavity contains an elastic tongue that hooks onto the hard barb on the terminal. Pressing the tongue with a pick allows the terminal to be removed from the housing.
