Connector

This creation is about a connector. The function of the connector is to electrically connect different electronic components, especially cables, circuit boards, etc., in a simple plug-in process, and the connection is removable or unpluggable.

There are a number of different types of connectors available, which can be attributed to a number of different conditions of use, which in turn have different requirements for the connector, wherein non-essential requirements are usually ignored in order to reduce costs. Plug-ins are usually produced in large quantities, so even small cost differences are important.

Among them, the connector is often valued to prevent moisture from invading the inside of the connector itself, as well as the tightness of the space inside the plug-in combination (two or more interconnected connectors), usually used for maneuvering. The connector in the vehicle engine room must meet this sealing requirement.

The sealing construction of a connector typically results in higher costs or increased assembly costs and, in turn, increases the price of a single connector.

The main purpose of this creation is to provide a connector that is low in production cost and sealed.

This purpose can be achieved by applying the first item of the patent scope of this creation, this creation The connector preferred embodiment is described in other sub-items.

The basic concept of the creation is to use a relatively elastic material to achieve the seal of the connector. During the assembly process, when the component for transmitting signals or supplying power is placed in the casing, the casing can be It is compressed by a suitable mechanism to abut against the electronic component under pre-stress and thereby form a seal in the gap between the electronic components.

Accordingly, the connector of the present invention comprises (at least) a contact element having an electrically conductive connection to (at least) one of the conductors of the cable at (at least) one end thereof and (at least) a region surrounding the contact element and the cable a housing outside the segment, the connector being characterized in that the housing has (at least) a receptacle extending in the direction of the long axis of the connector for receiving the contact element and the cable section, and (at least) in the cable section The segment has (at least) a slit opening (the length of which is preferably a multiple of its width), the opening extending from the receiving portion to the outer side of the outer casing, and also having a mechanism for compressing the outer casing within the cable section, The outer casing is pressed against the cable section.

Wherein, the slit opening has a width when the outer casing is not subjected to an external force, and is reduced when compressed, and the degree of deformation is preferentially reduced to zero, that is, the slit is opened in the connector, and the shape is changed. The housing can then be completely closed.

Since the outer periphery of the cable section has a slit opening in the outer casing (the opening is gradually closed during the compression process), the outer casing or the cable outer casing material can be prevented from forming a wavy or wrinkled fault on the contact surface between the outer casings. This fault will have a negative impact on the tightness of the contact points.

The priority is that the outer dimension of the cable section (preferably the outer diameter) is larger than the inner dimension (preferably the inner diameter) in the cable section of the receiving section, thereby making up for the elastic material on the cable. Deformation (compression) caused by the outer casing over the extent of the segment.

In addition, the creation preferably has an assembly opening, the opening extending from the receiving portion to the outside The outer side of the housing, and the connector can be assembled from its side by the contact element and the cable section, wherein one or a section of the opening can be particularly preferably a slit opening.

In addition, the contact element can be fixed to the inside of the housing from the lateral direction (especially in the radial direction) by a latching connection, whereby the contact element can be stably located in the housing, which is inserted into the connector and the corresponding connector. The group has advantages and simplifies the assembly process of the connector. The advantage of the locking connector of the present connector is that since the outer casing is composed of a relatively variable (especially elastic) material, compression can be used to create the sealed state of the present invention; this variability of the outer casing is particularly It is elastically applied to the latching connection, for example, the slit and the assembly opening are deformed to a narrow shape on a section such that when the contact element is loaded, this section is temporarily enlarged.

In addition, the contact element can also be fixed inside the housing in the direction of the long axis, thereby assisting in generating the insertion or extraction force generated when the connector and another corresponding connector are inserted or removed; at this time, the contact element In the direction of the major axis, in particular, a snap-fit can be achieved and is achieved by the same mechanism as the laterally fixed latching connection, such as causing, for example, a slit or a partial reduction of the assembly opening (at least) a projection, a projection Cooperating with (at least) a protrusion on the contact element, that is to say in contact with each other.

In a preferred embodiment of the present connector, the outer casing has an inner casing having a receiving portion, a slit or an assembly opening, and a (single or multi-piece) outer casing surrounding the inner casing .

The outer box can be preferentially used or has the function of compressing the inner box. Therefore, when the connector is assembled, the outer box can be slid in the plugging direction to the inner box, and the contact surface between the inner box and the outer box is When slidingly contacting each other, it gradually becomes larger in the plugging direction, so that the inner box is compressed when the outer box is slipped. Of course, the contact surface of the outer box may additionally have a gradually increasing characteristic.

The outer box can be preferentially in a tubular configuration, and the inner box can be completely covered except the plug end and the cable end, wherein the outer box can be slipped by the plug end of the connector when the connector is assembled, and the outer box can be easily The inner box produces a compression effect.

In a preferred embodiment of the present invention, the longitudinal section of the inner box (preferably along the plane of symmetry on the symmetrical connector) has a U-shaped cross section with a cable-side open end on at least one section, one The inner casing having such a cross section in the axial direction can constitute a receiving portion and an opening, and the use of plastic as a material can reduce the cost and simplify the production, wherein the U-shaped cross section is characterized in that the two wings have a lower rigidity against the pressure, and The required variability of the outer casing is sealed to the cable section.

Such an inner box having a U-shaped cross section can accommodate more than one contact element (preferably in a flat arrangement) particularly on the same longitudinal plane (isolated with spacers if necessary).

When more than two contact elements are to be inserted into the outer casing, it is preferred to have two (or more) U-shaped segments on a longitudinal plane such that the inner casing forms an E-shaped end with a cable-side open end on at least one of the segments. section.

At the same time, at least two contact elements (separated by spacers) are mounted in parallel in the longitudinal faces of the two E-sections.

In order to further improve the sealing performance of the original connector, the outer box extends beyond the inner box at the cable end of the connector and forms a flange, and the outer box and the inner box form a groove formed beside the flange ( At least a portion can be filled with a filler (especially a watering block).

For the purpose of achieving the above-mentioned purpose and effect of the above-mentioned use, the preferred embodiments are described in the following, and the details are as follows: For the embodiment of the present application, please refer to the first figure. As shown in the fourth figure, the connector shown in the drawings comprises a two-piece housing having an inner box 1 and an outer box 2.

The outer casing 2 is a tubular structure having a square cross section and completely accommodates the inner casing 1 when the connector is assembled.

The inner box 1 constitutes a total of four accommodating portions 3 which pass through the entire inner casing 1 along the axial direction of the connector. When the connector is assembled, the metal contact elements 4 are mounted in the accommodating portion 3 and one is a press-fit device 5) a section of electrically and mechanically connected cable 6 comprising a wire and a film covering the wire, the wire being connected to the associated contact element 4; the cable 6 can also have an outer wire and a An insulating layer separating the outer wire from the inner wire, the axially parallel receiving portion 3 (this axial direction is the same as the plugging direction when the connector is not shown in the corresponding connector plug) a circular cross section (without a fixed diameter), in the radial direction, a long strip-shaped assembly opening 7 is formed in each of the accommodating portions 3, which extends completely to the end of the cable 6 of the inner box 1, but does not extend to reach the plug end; The longitudinal plane of the accommodating portion 3, which is arranged in a stack as shown in the two figures in the inner casing 1, is an E-shaped cross section, wherein the open end formed by the flank of the cross section is the end of the cable 6, and the opening 7 is assembled in the inner casing 1. The section of the inner box 1 in the section in which it is located may be referred to as a double E-type configuration.

The unit formed by the contact element 4 and the section of the cable 6 can be placed by means of the assembly opening 7, which can be achieved by parallel movement.

The fourth and fifth figures show the state before the inner box 1 and the contact element 4 and the cable 6 connected thereto are assembled, and the sixth figure shows the state of the same assembly in the middle step of the assembly process, where the contact element 4 And the cable 6 section is placed in the accommodating portion 3, as can be seen from the fourth to sixth figures, the assembly opening 7 is wrapped around the cable 6 section in the compression section 8 of the inner casing 1, and the compression zone is The outer diameter of the segment 8 is small, and the thinner section of the assembly opening 7 in the compression section 8 exhibits a slit opening 7 configuration and is narrowed and completely sealed when the compression section 8 is compressed; likewise, In the blocking section 9, the assembly opening 7 is also thinner than the outer diameter of the contact element 4 on the corresponding section, respectively, so that when the contact element 4 is placed, the inner casing 1 must be at this section and at the slit opening 7 It can be temporarily expanded, which can be achieved by the elastic material used in the inner casing 1. The inner casing 1 can also be made of a thermoplastic elastomer, in particular, so as to have elastic properties, which can also be produced by injection or other thermoforming techniques.

The two latching sections 9 of the assembly opening 7 are each formed by two latching projections which are inclined relative to the outer side of the associated inner casing 1 so that the contact element 4 can be easily inserted in the axial direction of the connector. The section of the contact element 4 which is assigned to each of the assembly openings 7 between the two latching sections 9 respectively forms a circumferential projection 10 , whereby the contact element 4 can be snap-fitted in the axial direction; The portion 3 has a smaller diameter than the adjacent segments within the limits of the blocking section 9.

In order to isolate the receptacle 3 and the contact element 4 placed therein from the outside of the cable 6 of the connector, the compression section 8 of the inner box 1 is squeezed by the displacement of the outer casing 2 when the plug-in end is assembled. At this time, the compression section 8 at least partially has a surface area gradually increasing in the direction of the end of the cable 6. By this compression, the inner box 1 is pressed in the section of the cable 6 in the compression section 8, as shown in the third figure. Show that When the slit opening 7 (i.e., the assembly opening 7 located in the compression section 8) is compressed, it is sealed as completely as possible so that a complete seal is formed between the cable 6 section and the compression section 8, and the cable 6 outer membrane The deformation also causes the slit opening 7 to be in close contact within the compression section 8, and the film is also made of a relatively resilient material.

The outer casing 2 is longer than the inner casing 1, whereby a larger flange can be formed at the end of the connector cable 6, and the flange and the cable 6 end of the inner casing 1 together form a recess 11, this one The groove 11 can be filled with a watering block (not shown), thereby improving the sealing of the cable 6 end and the mechanical combination between the components of the connector; in this case, via the inner box The sealing effect produced by the compression of the compression section 8 can have the function of preventing the pouring block from penetrating into the receptacle 3 before hardening.

In summary, the present invention has achieved the intended use and effect, and is more desirable and practical than the prior art. However, the above embodiments are only specifically described for the preferred embodiment of the present invention.
