Description

Connector with a locking member

Technical Field

The utility model relates to a connector.

Background

An electronic connector is a conductor device for connecting electrical lines. The component can be used as a terminal for connecting different elements in a circuit system, or can be used for providing power and data connection between different circuit systems and devices. It is widely used in various electric lines to connect or disconnect electric circuits. Such connections may be temporary and convenient to plug and unplug, or may be permanent junctions between electrical devices or cables.

Fig. 1 shows a connector 1 as prior art. In assembly, the two rows of inner terminals 2a, 2b of the connector 1 are inserted into the pre-formed insulators 3a, 3b, respectively, and then into the socket body 4. However, since the insulating members 3a, 3b are elements formed separately from the inner terminals 2a, 2b, dimensional errors are easily generated at the time of production due to process or design problems, and thus cannot be tightly fitted with the inner terminals 2a, 2b, for example, the inner diameters of the insulating members 3a, 3b are larger than the outer diameters of the inner terminals 2a, 2b so that there is a large gap between them in a state where the inner terminals 2a, 2b are inserted into the insulating members 3a, 3 b. The shield 5 of the connector 1 is monolithic, and can provide only crosstalk shielding between the inner terminals 2a and 2b, but cannot shield interference such as crosstalk from the outside.

Detailed Description

Other advantages and technical effects of the present invention will be apparent to those skilled in the art from the disclosure of the present specification, which are described in the following embodiments. The present invention is not limited to the following embodiments, and various other embodiments may be implemented or applied, and various modifications and changes may be made without departing from the spirit of the present invention.

Hereinafter, specific embodiments of the present invention will be described in detail based on the drawings. The drawings are for simplicity and clarity and are not intended to be drawn to scale, reflecting the actual dimensions of the structures described. To facilitate understanding, identical reference numerals have been used, where possible, to designate identical elements that are common to the figures. The figures are not drawn to scale and may be simplified for clarity. Elements and features of one embodiment may be beneficially incorporated in other embodiments without further recitation. In the drawings, the x-y-z spatial coordinate axes are labeled for ease of understanding, however, this is not intended to limit the scope of the present application.

Hereinafter, an example of the connector according to the present invention will be described with reference to fig. 2 to 8.

As shown in fig. 2A to 2D, the exemplary connector 100 may include a socket body 110, a plastic housing body 120, and a shield 130. The plastic housing body 120 may be detachably mounted to the socket body 110. The socket body 110 may include at least two rows of conductive inner terminals 111 therein, and a first end 111a of each conductive inner terminal 111 may extend from an end surface 110a of the socket body 110 into the receiving cavity 121 of the plastic housing body 120, and a second end 111b may extend from the other surface 110b of the socket body 110. By way of example, the drawing shows the case where the connector 100 includes 2 rows by 2 columns, i.e., 4 conductive inner terminals 111, but it is contemplated that the connector 100 may include other numbers of conductive inner terminals 111 as well (e.g., 2 or more rows and each row may include any other number).

The term "row" of the present disclosure refers to, for example, in fig. 2A, a plurality of conductive inner terminals 111 arranged in the width direction (x direction in the drawing) of the plastic case body 120 at the side of the opening of the plastic case body 120. The term "row" refers to, for example, in fig. 2A, a plurality of conductive inner terminals 111 arranged in the height direction (z direction in the drawing) of the plastic case body 120 at the side of the opening of the plastic case body 120. It is understood that the conductive inner terminals 111 of the same row have the same length, and the conductive inner terminals 111 of different rows have different lengths. For the conductive inner terminal 111 on the inner side, the length of each of the first end 111a and the second end 111b is smaller than that of the conductive inner terminal 111 on the outer side.

The shield 130 may include an inter-terminal shield plate 131 and an outer shield plate 132. The inter-terminal shield plate 131 may space the second ends 111b of the conductive inner terminals 111 of different rows from each other, and the outer shield plate 132 may be disposed outside the outermost row of the conductive inner terminals 111.

The connector 100 may further include an insulating layer 140 and a conductive outer terminal 150. The insulating layer 140 may cover the first end 111a of each conductive inner terminal 111. The number of the conductive outer terminals 150 may correspond to the number of the conductive inner terminals 111. The conductive outer terminals 150 may abut against the end surface of the socket body 110, be positioned in the receiving cavities 121 of the plastic housing body 120, and each surround the corresponding conductive inner terminal 111. The conductive outer terminal 150 may be sleeved outside the insulating layer 140.

In the example shown in fig. 2A-2D, the connector 100 is a right angle connector. In the case of a card edge connector, the conductive inner terminal 111 may be an L-shaped terminal in which the first end 111a is at right angles to the second end 111 b. The second end 111b of the conductive inner terminal 111 protrudes from the bottom surface of the socket body 110. That is, the other surface 110b of the socket body 110 may be a bottom surface. A right-angle type connection via the conductive inner terminal 111 can thereby be realized.

However, it is contemplated that the present invention is not limited to right angle connectors and that the connector 100 may be any other angle connector.

Each of the above components will be described in further detail below with reference to fig. 3 to 8.

Fig. 3 is a perspective view illustrating the socket body 110 of the connector 100. For clarity, the conductive inner terminal 111 is not shown in fig. 3. The socket body 110 may be formed with various materials (conductive or non-conductive material, preferably conductive material, and more preferably zinc alloy) via a molding process (e.g., die casting, etc.). As one example, a case where the end face 110a of the connector 100 is formed with the cylindrical passage 112 is shown here, but it is conceivable that the end face may not include the passage 112 but be formed with only a through hole.

Referring back to fig. 2B and 2D, a passage 113 through which the second end 111B of the conductive inner terminal 111 passes may be formed at the other surface 110B of the socket body 110. The other side 110b shown in the drawing is the bottom surface of the socket body 110, i.e., the case of a right-angle connector. However, it is contemplated that the other side 110b can be other sides or opposing sides. Preferably, the channels 113 may be formed as open grooves distributed in a row as shown in fig. 2B, which extend to the rear end of the socket body 110, so that the conductive inner terminals 111 are mounted into the socket body 110 from the rear side of the socket body 110. Further preferably, in addition, as shown in fig. 2D, an insertion groove 114 into which the shield member 130 is inserted may be formed on the other surface 110b of the socket body 110 to facilitate mounting the shield member 130 into the socket body 110 and dismounting the shield member 130 from the socket body 110.

Fig. 4 is a perspective view illustrating the conductive outer terminal 150 of the connector 100. Preferably, the conductive outer terminal 150 may be, for example, a metal sleeve. As a preferred example, fig. 4 shows one non-limiting example of the conductive outer terminal 150, wherein the conductive outer terminal 150 may include an insertion portion 151 and an exposed portion 152. The insertion portion 151 may be connected to the end surface 110a of the connector 110 by, for example, insertion. For example, in the case where the end surface 110a is formed with a cylindrical passage 112 (as shown in fig. 3), the insertion portion 151 may be inserted into the passage 112 and fixed in place, as shown in fig. 5. In the case where the conductive inner terminal 111 is coated with the insulating layer 140, the insertion portion 151 may surround the insulating layer 150. The diameter of the exposed portion 152 may be larger than that of the insertion portion 151, and the exposed portion 152 is disposed in the receiving cavity 121 of the plastic case body 120 described below with reference to fig. 6.

Fig. 6 is a perspective view showing the plastic housing body 120 of the connector 100. One end of the plastic housing body 120 may include a fitting structure or a snap-fit structure to fit or snap-fit with a corresponding structure on the sidewall or end surface 110a of the socket body 110, thereby being detachably mounted to the socket body 110. The plastic case body 120 defines therein a receiving cavity 121 for receiving the first end 111a of the conductive inner terminal and a conductive outer terminal 150 described later. After the plastic housing body 120 is mounted to the socket body 110, the first end 111a of the conductive inner terminal, an insulating layer 140 described below, and a conductive outer terminal 150 fitted over the insulating layer 140 are located in the receiving cavity 121.

Fig. 7A shows a schematic view of a conductive inner terminal 111 of the connector 100. Fig. 7A shows a case where the conductive inner terminal 111 is an L-shaped terminal, but the conductive inner terminal 111 may have other angles or have a curvature. Fig. 7A schematically shows only 1 column and 2 rows for 2 conductive inner terminals 111, but it is conceivable that the case of other columns and/or more rows of conductive inner terminals 111 may be similar.

Fig. 7B shows a schematic diagram after an insulating layer 140 is formed on the conductive inner terminal 111 shown in fig. 7A. The insulating layer 140 may be formed on a part or all of the conductive inner terminal 111 by various molding methods including, but not limited to, insert molding (insert molding), dip molding, spray molding, and the like, for example. As an example, the insulating layer 140 may be clad on the first end 111a of each conductive inner terminal 111. The term "wrapped" in this context is intended to mean tightly wrapped with substantially no gaps or only very small gaps therebetween.

The insulating layer 140 of fig. 7B is merely an example, and other shapes or types of insulating layers 140 may be formed in other portions of the conductive inner terminal 111. For example, the insulating layer 140 may also be formed on the second end 111b of the conductive inner terminal 111.

Fig. 8 is a perspective view illustrating the shield 130 of the connector 100. Further, fig. 2B and 2D respectively show a state in which the shield 130 is mounted in place.

As shown in fig. 8, the shield 130 may include an inter-terminal shield plate 131 and an outer shield plate 132.

The inter-terminal shield plate 131 may be used to be positioned between adjacent rows of conductive inner terminals 111 for providing shielding (e.g., crosstalk shielding) between the adjacent rows of conductive inner terminals 111, and the outer shield plate 132 may be used to be positioned outside the outermost row of conductive inner terminals 111 (the outer shield plate 132 shown in fig. 8 is used to be positioned outside the outermost conductive inner terminal 111) for providing shielding (e.g., crosstalk shielding) of the conductive inner terminals 111 from the outside. Optionally, the shield 130 may further include a connection portion 133 for connecting the inter-terminal shield plate 131 and the outer shield plate 132. Preferably, the connection part 133 may be fitted with the other surface 110b of the socket body 110 so as to be fixed in place. For example, as shown in FIG. 2B, the connection 133 may abut a structure provided on an inner wall of the channel 113, thereby being fixed in place. Further, the connecting portion 133 may be located not only on the side surface of the inter-terminal shield plate 131 shown in fig. 8 but also on the bottom surface, for example, across between the bottom surface of the inter-terminal shield plate 131 and the bottom surface of the outer shield plate 132. At this time, the connection parts 133 are fitted with corresponding structures on the bottom surface of the socket body 110, for example, are fitted into corresponding grooves, to be fixed in place.

For example, as shown in fig. 2B and 2D, when the shield 130 is mounted to the connector 100, for example, by being inserted into the receptacle body 110 from the other face 110B of the receptacle body 110, the inter-terminal shield plates 131 may be inserted into the slots 114 and between the two rows of conductive inner terminals 111. The connecting portion 133 may abut against an inner wall of the channel 113. The outer shield plate 132 may be located outside the outermost row of conductive inner terminals 111. Thus, the inter-terminal shield plate 131 can provide shielding between different rows of the conductive inner terminals 111, and the outer shield plate 132 provides shielding between the conductive inner terminals 111 and the outside. The outer shield 132 may also shield the notch 115 at the rear end (also referred to as an end face) of the receptacle body 110, thereby acting as a rear wall of the connector 100. In this way, the outer shield plate 132 can provide electromagnetic shielding to the outside while protecting the conductive inner terminal 111 on the inside.

Fig. 8, 2B and 2D only show an example where the connector 100 includes two rows of terminals and the shield 130 has 1 inter-terminal shield plate 131 and 1 outer shield plate 132, but it is contemplated that the shield 130 may include two or more inter-terminal shield plates 131 depending on the actual terminal arrangement. Generally, the number of inter-terminal shield plates 131 is less than 1 than the number of rows of conductive inner terminals 111.

Further, the length (z direction in fig. 8) of the inter-terminal shield plate 131 depends on the length of the second end 111b of the conductive inner terminal 111 inside its insertion position, as shown in fig. 2D. Preferably, the inter-terminal shield plate 131 extends to the sidewall of the channel 113 where the corresponding inner conductive inner terminal 111 is located to completely separate the second ends 111b of the conductive inner terminals 111 at both sides thereof. The outer shield plate 132 may extend in a length direction to a sidewall of the top of the socket body 110. In this case, the outer shield plate 132 may abut against a sidewall of the top of the socket body 110 in the height direction and abut against a sidewall of the passage 113 in which the outermost row of the conductive inner terminals 111 is located in the length direction of the socket body 110.

Preferably, as shown in fig. 8, 2B and 2D, the inter-terminal shielding plate 131 and the outer shielding plate 132 may be parallel to each other. Further preferably, the inter-terminal shielding plate 131 and the outer shielding plate 132 may be parallel to the end surface 110a and/or parallel to the second end 111a of the conductive terminal 111. However, it should be understood that the arrangement angle of the inter-terminal shielding plate 131 and the outer shielding plate 132 depends on the orientation of the second end 111a of the corresponding conductive inner terminal 111. Depending on the type of connector, in particular, the orientation of the conductive inner terminal 111, the arrangement angles of the inter-terminal shield plates 131 and the outer shield plates 132 can be adjusted accordingly.

Through the exemplary connector 100 of the present invention, at least the following advantageous technical effects can be achieved:

by providing the shield member 130 including the inter-terminal shield plate 131 and the outer shield plate 132, it is possible to realize shielding between the conductive inner terminals 111 from each other, and to realize shielding between the conductive inner terminals 111 and the outside, and it is possible to obtain a better shielding effect and improve the electromagnetic shielding performance of the connector 100.

By coating the insulating layer 140 on the conductive inner terminal 111, it is possible to make the connector terminal structure more stable and reduce the occurrence of loosening or even falling off of the insulating layer 140, compared to the case where an insulating member is formed separately and is fitted over the conductive inner terminal 111.
